clearance<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The blanking gap Z is the difference in the size of the working part between the blanking die and the concave die. The blanking gap has a great influence on the blanking process. Its size directly impacts the quality of the punched part and also has a significant impact on the die life. The blanking gap is the most important process parameter to ensure a reasonable blanking process. In actual production, the value of the reasonable clearance is determined by experimental methods. Since there is no absolute reasonable clearance value and the specific requirements of each industry are not the same, each industry and even each company has its own blanking clearance table, which is often chosen by referring to the relevant blanking clearance table when determining specific clearance value. Generally speaking, a smaller reasonable clearance is good for improving the quality of the punched part, while a larger reasonable clearance is good for improving the lives of the die. Therefore, a larger reasonable clearance should be used to ensure the quality of the punched part.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, the double-sided clearance Z for punching can be calculated according to the following formula:<\/p>\n\n\n\nZ=mt\n\n\n\n<p class=\"wp-block-paragraph\">m\u2014\u2014\u2014\u2014Coefficient, see table below;<br>t\u2014\u2014\u2014\u2014Sheet thickness, mm.<\/p>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">Machinery manufacturing and automobile, tractor industry m value<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>\u0627\u0633\u0645 \u0627\u0644\u0645\u0627\u062f\u0629<\/td><td>m value<\/td><\/tr><tr><td>08 steel, 10 steel, brass, pure copper<\/td><td>0.08~0.10<\/td><\/tr><tr><td>Q235, Q255, 25 steel<\/td><td>0.1~0.12<\/td><\/tr><tr><td>45 steel<\/td><td>0.12~0.14<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\">The m-value of the electrical instrumentation industry<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>Material Type<\/td><td>\u0627\u0633\u0645 \u0627\u0644\u0645\u0627\u062f\u0629<\/td><td>m value<\/td><\/tr><tr><td>Metal Material<\/td><td>Aluminum, pure copper, pure iron<\/td><td>0.04<\/td><\/tr><tr><td>Metal Material<\/td><td>Hard aluminum, brass, 08 steel, 10 steel<\/td><td>0.05<\/td><\/tr><tr><td>Metal Materials<\/td><td>Tin-phosphor bronze, beryllium alloy, and chrome steel<\/td><td>0.06<\/td><\/tr><tr><td>Metal Materials<\/td><td>Silicon steel sheet, spring steel, high carbon steel<\/td><td>0.07<\/td><\/tr><tr><td>Non-metallic materials<\/td><td>Paper cloth, leather, asbestos, rubber, plastic cardboard, adhesive cardboard, adhesive sheet, mica sheet<\/td><td>0.02<br>0.03<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-3-determination-of-working-part-size-of-convex-and-concave-dies\">3. <strong>Determination of working part size of convex and concave dies<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">In blanking operation, the size and accuracy of the working part of the die is the primary factor affecting the tolerance level of the size of the blanked part, and the reasonable clearance of the die also depends on the size of the working part of the die and its tolerance to ensure. Therefore, when determining the size of the working part of the convex and concave dies and their manufacturing tolerances, it is necessary to take into account the law of punching deformation, tolerance grade of the punched part, die wear, and manufacturing characteristics.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Basic principles of punching convex and concave die size calculation<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">When punching, the diameter of the hole determines the size of the convex die, and the clearance is obtained by increasing the size of the concave die. In the case of drop, the profile size determines the size of the concave die, and the clearance is obtained by reducing the size of the convex die. As the concave die wears out, it increases the size of the drop part, and the convex die wears out, it decreases the size of the punched part. In order to improve the die life, the size of the concave die should be made to the minimum limit size of the drop part and the size of the convex die to the maximum limit size of the punched part when making a new die.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Method to ensure the clearance of punching die<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Specify the dimensions and tolerances of the convex die and concave die separately and manufacture them separately. The clearance requirement is ensured by the size and manufacturing tolerance of the convex and concave dies. This processing method provides interchangeability of convex and concave dies, short manufacturing cycle time, and is easy to manufacture in batches.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The clearance is ensured by the method of single-matching the convex and concave dies to each other. After machining, the convex and concave dies must be matched to each other and are not interchangeable. Usually, the concave die is chosen as the reference die for drop parts and the convex die is chosen as the reference die for punching parts. The dimensions and tolerances are marked on the part diagram of the benchmark die, and the part diagram of the matching non-benchmark die is marked with the same basic dimensions as the benchmark die, but no tolerance is marked, and the punching clearance is matched according to the actual dimensions of the benchmark die, and the clearance value is guaranteed to be within Z<sub>\u062f\u0642\u064a\u0642\u0629<\/sub>~Z<sub>\u0627\u0644\u0623\u0639\u0644\u0649<\/sub>.

Crank presses are divided into open presses and closed presses according to the structural characteristics of the machine body. The open type press worktable is open in the front, left, and right side, which is easy to install and adjust the die and operation, but the rigidity is poor, the tonnage is 25kN~4MN, the figure below shows several types of open type press; the closed type press is frame type processing, open in front and back, the rigidity is better, the tonnage is more than 1. 6MN.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"554\" height=\"227\" src=\"https:\/\/hecter.cn\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"http:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-8.png\" alt=\"Types of open type presses\" class=\"wd-lazy-fade wp-image-2242\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-8.png 554w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-8-150x61.png 150w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-8-300x123.png 300w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-8-18x7.png 18w\" sizes=\"(max-width: 554px) 100vw, 554px\" \/><figcaption>Types of open type presses<\/figcaption><\/figure><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Although there are more types of crank presses, the working principle is basically the same. Simply put, it is to increase the force and change the form of motion through the crank structure (crank linkage mechanism, crank elbow mechanism, etc.) and use the flywheel to store and release energy to make the crank press produce large working pressure to complete the stamping operation. The following is an example of JB23-63 crank press to explain its structure and movement principle. JB23-63 crank press belongs to open type tiltable press, see the figure below.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img class=\"wd-lazy-fade\" decoding=\"async\" width=\"554\" height=\"331\" src=\"https:\/\/hecter.cn\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"http:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-9.png\" alt=\"JB23-63 crank press structure and principle of motion1-Motor; 2-Pinion pulley; 3-Large pulley; 4-Pinion gear; 5-Large gear; 6-Clutch.7-Crankshaft; 8-Brake; 9-Linkage; 10-Slider; 11-Upper die; 12-Lower die13-Pad; 14-Table; 15-Body\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-9.png 554w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-9-150x90.png 150w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-9-300x179.png 300w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-9-18x12.png 18w\" sizes=\"(max-width: 554px) 100vw, 554px\" \/><figcaption>JB23-63 crank press structure and principle of motion<br>1-Motor; 2-Pinion pulley; 3-Large pulley; 4-Pinion gear; 5-Large gear; 6-Clutch.<br>7-Crankshaft; 8-Brake; 9-Linkage; 10-Slider; 11-Upper die; 12-Lower die<br>13-Pad; 14-Table; 15-Body<\/figcaption><\/figure><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">When the press is in motion, motor 1 transmits the motion to the large pulley 3 through the V-belt, and then to the crankshaft 7 through the pinion 4 and large gear 5. The upper end of the connecting rod 9 is mounted on the crankshaft, and the lower end is connected to the slider 10 to change the rotational motion of the crankshaft into the reciprocating linear motion of slider, and the highest position of the slider 10 is called the upper stop (dead) position, while the lowest position is called the lower stop (dead) position. Due to the need for production process, slider sometimes moves and sometimes stops, so it is equipped with clutch 6 and brake 8. Since the press has short time for process operation during the whole working time cycle, most of the time is no-load empty range. In order to make the motor load evenly and use equipment energy effectively, thus the flywheel is equipped and the big belt pulley takes off the pulley action at the same time.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the press is working, the upper die 11 of the used die is mounted on the slider, and the lower die 12 is mounted directly on table 14 or with pad 13 on the table surface, it can get the suitable closing height. At this time, the material is placed between the upper and lower dies, that is, it can be punched or another deformation process to make the workpiece.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-key-points-of-punching-die-design-and-application\"><strong>The key points of punching die design and application<\/strong><strong><\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The punching process is completed by punching die, which is the key to ensure the shape, size, and accuracy of the blanked parts. Therefore, the punching process of the sheet material depends largely on the design of an economic, reasonable, and practical punching die.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-1-punching-processability\"><strong>1. Punching processability<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Need to carefully analyze the punching process of the parts, so that the developed processing technology and die structure can meet the needs of processing. For example, for the punching process of the plate with sharp corners, the process can generally be arranged by using the principle that two straight lines intersect to form a sharp corner. In figure (b) below, a straight edge of the convex die intersects with one side of the strip to obtain the workpiece shown in figure (a) below; in figure (d) below, the strip is fed from the right to the left, one side of the profile is punched out first, and then the workpiece is punched out to obtain the workpiece shown in figure (c) below. If the workpiece is to be punched in a single pass, the working parts such as cam and concave dies are often inserted to facilitate subsequent maintenance and replacement.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"542\" height=\"116\" src=\"https:\/\/hecter.cn\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"http:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-10.png\" alt=\"Punching of sharp-edged plate parts\" class=\"wd-lazy-fade wp-image-2244\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-10.png 542w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-10-150x32.png 150w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-10-300x64.png 300w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-10-18x4.png 18w\" sizes=\"(max-width: 542px) 100vw, 542px\" \/><figcaption>Punching of sharp-edged plate parts<\/figcaption><\/figure><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Another example is that for the dense holes on the plate material, the punching process is poor parts punching, if the one-time punching is not strong enough concave die, and the punched parts are prone to hole edge material convex deformation, at this time, the available interval position, only half of the concave die, the first time with the stopper pin B blocking material, punching a few holes I, the second time with the stopper pin A blocking material, punching a few holes II.

Such as processing 2.5 mm thick 20 steel made of punching parts processing, if the roughness Ra requirements are not less than 0.8 ~ 1. 6\u03bcm, and processing hole accuracy up to IT9 level, then the use of ordinary punching die simply can not meet the requirements, at this time, the need to use precision punching or the use of extrusion light processing technology.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-3-punching-sequence-of-a-single-process-punching-die\">3. <strong>Punching sequence of a single process punching die<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">When a single process punching die is used to process plate material, the punching sequence should be reasonably arranged, mainly with the following principles.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>First drop the material before punching or notching, and the positioning reference of the subsequent processes should be consistent to avoid positioning errors and size chain conversion.<\/li><li>When punching holes of different sizes and close to each other, in order to reduce the deformation of the holes, the larger holes should be punched first and then the smaller ones.<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-4-progressive-die-punching-sequence\"><strong>4. Progressive die punching sequence<\/strong><strong><\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">When using a progressive die to process sheet material, the arrangement of punching sequence is mainly based on the following principles.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Punch or notch first, and drop or cut off last. The first punched hole can be used as the positioning hole for the subsequent process, and when the positioning is also required high, the process hole (generally two) can be punched specifically for positioning.<\/li><li>When using fixed distance side edge, the cutting process of fixed distance side edge is arranged to be carried out at the same time as the first punching, so as to control the feeding distance. When two fixed pitchside edges are used, they can be arranged as one in front of the other or side by side.<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-5-the-relationship-between-production-volume-and-processing-accuracy\">5. <strong>The relationship between production volume and processing accuracy<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">It is necessary to carefully analyze and take into account the relationship between the production volume and processing accuracy of the punched processed parts, so as to determine the appropriate die type and design the corresponding die structure. For example, a simple punching die as shown in the figure below can be used for punching parts with small production volume and low processing accuracy. The convex die 2 and concave die 3 are positioned on the upper and lower templates by the mounting plate 4 where the hole types correspond to each other, and the rubber sleeve 1 is used to press and dematerialize the material. However, if the processing accuracy is high, even if the production batch is not large, a guide plate die or die holder-guided punching die should be used.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-6-force-of-mold-structure\">6. <strong>Force of mold structure<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The working parts of the designed die and the force of the die structure need to be carefully analyzed so that measures can be taken during the design process or the structure of the die can be designed to be improved. For example, for the punching of small holes such as plates&nbsp;or pipes, the working conditions of the convex die are poor, and it is easy to break after the force is applied. In other words, the thickened part of the small die 3, the unloading plate 5 and the guide bush 4 are sliding together to play a guiding role, and the clearance between the working part of the die and the guide bush should be slightly larger to improve the die life.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img class=\"wd-lazy-fade\" decoding=\"async\" width=\"554\" height=\"170\" src=\"https:\/\/hecter.cn\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"http:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-12.png\" alt=\"Simple punching die                                   Self-guiding of small convex  1-Rubber sleeve; 2-Convex die;             1-Gasket plate; 2-Fixed plate; 3-Small convex 3-Concave die; 4-Mounting plate                           4-Guide sleeve; 5-Discharge plate\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-12.png 554w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-12-150x46.png 150w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-12-300x92.png 300w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-12-18x6.png 18w\" sizes=\"(max-width: 554px) 100vw, 554px\" \/><figcaption> Simple punching die                                   Self-guiding of small convex <br> 1-Rubber sleeve; 2-Convex die;             1-Gasket plate; 2-Fixed plate; 3-Small convex <br>3-Concave die; 4-Mounting plate                           4-Guide sleeve; 5-Discharge plate<\/figcaption><\/figure><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">For example, when punching the various notches shown below in the shear or fallen semi-finished products, since the punching notch is not a closed structure, the horizontal&nbsp;pressure on the side of the die and concave die edge will not be balanced to cancel each other, in order to eliminate the lateral force may cause the notched die to shift and lead to uneven punching clearance and other effects, or make the notched die skewed or even broken and other fatal defects, therefore, in the mold design, the following processing methods are usually used.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"513\" height=\"117\" src=\"https:\/\/hecter.cn\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"http:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-13.png\" alt=\"Various shapes of notches\" class=\"wd-lazy-fade wp-image-2247\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-13.png 513w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-13-150x34.png 150w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-13-300x68.png 300w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-13-18x4.png 18w\" sizes=\"(max-width: 513px) 100vw, 513px\" \/><figcaption>Various shapes of notches<\/figcaption><\/figure><\/div>\n\n\n\n<ul class=\"wp-block-list\"><li>Reinforce the strength and rigidity of the notched convex mold<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example, increase the part size and choose high strength&nbsp;to&nbsp;die material to make it resist the frequent action of lateral force.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Set the positioning part corresponding to the punching notch<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Block 5 as shown in Figure (a) below.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img class=\"wd-lazy-fade\" decoding=\"async\" width=\"554\" height=\"207\" src=\"https:\/\/hecter.cn\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"http:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-14.png\" alt=\"Method to eliminate the influence of side internal forceConcave die; 2-Notched convex die; 3-Top bar; 4-Discharge plate; 5-Barrier\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-14.png 554w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-14-150x56.png 150w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-14-300x112.png 300w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/image-14-18x7.png 18w\" sizes=\"(max-width: 554px) 100vw, 554px\" \/><figcaption>Method to eliminate the influence of side internal force<br>Concave die; 2-Notched convex die; 3-Top bar; 4-Discharge plate; 5-Barrier<\/figcaption><\/figure><\/div>\n\n\n\n<ul class=\"wp-block-list\"><li>Anti-bias load structure<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">To reduce the lateral force on the slot in the blanking plate 3, guide pin 1 and guide pin 2 are designed on the upper die.

The general-purpose die structure is simple, and the operation of the corresponding upper and lower dies can be changed simply in the same die to realize the punching of parts of different shapes and sizes. Therefore, it is useful for production organization and management, shortening the production cycle of parts and reducing manufacturing costs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following figure (a) shows the universal blanking die structure where the upper and lower die holders are connected into a single die holder. Figures (b) and (c) below show the separate structure of the upper and lower die holders, mostly open-type dies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The C-shape punching dies&nbsp;shown in (a) below have a high coaxiality because the concave die hole and the guide bushing assembly hole on the C-shape holder are machined in one clamping.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The convex die 5 in the die is both the convex die for the punching process and is guided by the guide sleeve 4 mounted in the hole in the die holder 1, and the head also acts as a die handle to connect with the press slide. To ensure the accuracy of the punching die, the convex die 5 and the inner hole of the guide sleeve 4 should be machined to a clearance fit of H6\/h5 with a coaxiality of no more than 0.003mm; the concave die 2 is mounted directly in the lower hole of the die holder. The unloading plate 3 is fixed in the middle of the die holder with screws.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The entire die has a compact structure and good processing performance. Different shapes of the shaft and hole parts can be punched by changing the die shank convex die 5, concave die 2, and unloading plate 3 (working size and shape change).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Figure (b) below shows another general-purpose drop and punch die structure that can punch square, rectangular, and other shapes. The whole set of dies is very versatile.

The general installation principle of the punching die on the press is: first fix the upper die on the press slide, and then adjust the fixed lower die according to the position of the upper die. In the process of die installation, the press must be adjusted accordingly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The installation of the punching die is divided into two types: unguided punching die and guided punching die. The installation methods are as follows.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-1-installation-of-unguided-die\">1. Installation of unguided die<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The installation of unguided punching dies is more complicated, and the methods are as follows.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Before die installation, check the press and die.<\/li><li>Check the installation condition of the punching die. The closing height of the punching die must match the loading height of the press. The closing height of the die must be measured before installation. If the closing height of the die is too small to meet the above requirements, add a ground flat pad on the press table to make it meet the above requirements before mounting the die.<\/li><li>Place the punching die at the center of the press, see the figure below. The upper and lower dies are padded with pad 3.<\/li><li>Loosen the nut on press slide 4 and turn the press flywheel by hand or pry bar to lower the press slide to contact with the upper die plate 6 and make the die shank of the punch enter the die shank hole of the slide.<\/li><li>After the height of the slider is adjusted, fasten the die shank to the press slider.<\/li><li>Adjust the clearance of the convex and concave dies, i.e., pad the edge of the concave die with a cardboard1 or copper sheet equal to the thickness of the one-sided clearance value of the convex and concave dies, and adjust the clearance of the convex and concave dies with the transillumination method and make it even.<\/li><li>After the gap is adjusted, insert bolt 10 into the groove of the press table and fasten the lower die to the press by means of pressure block 8, pad 9, and nut 7. Note that the tightening of the bolts should be done symmetrically and in a staggered manner.<\/li><li>Start the press for test punching. In the process of test punching, if the die clearance needs to be adjusted, loosen the nut 7 slightly and use a hand hammer to gently hammer the lower die in the direction of adjustment according to the distribution of the die clearance until the die clearance is suitable.<\/li><\/ul>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img class=\"wd-lazy-fade\" decoding=\"async\" width=\"453\" height=\"264\" src=\"https:\/\/hecter.cn\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"http:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/sb6_\u526f\u672c.png\" alt=\"Installation and adjustment of unguided blanking die1 -Cardboard; 2 -Concave die; 3 -Spacer; 4 -Press slide5-Convex die; 6-Upper template; 7-Nut; 8-Press block9-Pad; 10-T-bolt\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/sb6_\u526f\u672c.png 453w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/sb6_\u526f\u672c-150x87.png 150w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/sb6_\u526f\u672c-300x175.png 300w, https:\/\/hecter.cn\/wp-content\/uploads\/2021\/06\/sb6_\u526f\u672c-18x10.png 18w\" sizes=\"(max-width: 453px) 100vw, 453px\" \/><figcaption>Installation and adjustment of unguided blanking die<br>1 -Cardboard; 2 -Concave die; 3 -Spacer; 4 -Press slide<br>5-Convex die; 6-Upper template; 7-Nut; 8-Press block<br>9-Pad; 10-T-bolt<\/figcaption><\/figure><\/div>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-2-installation-method-of-guided-punching-die\">2. Installation method of guided punching die<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The installation and adjustment of guided punching die are more convenient and easier than that of unguided die due to the guide pillar and guide bush guidance.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Make the technical preparation, cleaning of the die and press table, and inspection of the press before installation according to the installation requirements of unguided punching dies.<\/li><li>Put the closed die on the press table.<\/li><li>Separate the upper die from the lower die and pad the upper die with a wooden block or pad iron.<\/li><li>Lower the press ram to the lower pole and adjust it to make contact with the upper plane of the upper die plate.<\/li><li>Fasten the upper die and lower die to the press slider and pressure table respectively, with the screws fastened symmetrically and in a staggered manner. The slider should be adjusted so that when it is on the upper pole, the convex die does not escape from the guide plate or the guide sleeve does not fall farther than 1\/3 of the length of the guide column.<\/li><li>After fastening firmly, carry out test punching, and transfer to formal production after passing the test punching.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-quality-and-precision-of-sheet-blanking\">The quality and precision of sheet blanking<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The quality of the sheet blanking process refers to the quality of the cut-off surface, size and shape accuracy, etc. The surface roughness of the punched parts is generally below Ra12.5\u03bcm, and the specific values can be found in the table
