M\u00e1quinas de corte<\/h2>\n\n\n\n

De acordo com diferentes m\u00e9todos de transmiss\u00e3o, as m\u00e1quinas de corte s\u00e3o divididas em tipo de transmiss\u00e3o mec\u00e2nica e tipo de transmiss\u00e3o hidr\u00e1ulica. As m\u00e1quinas de corte com espessura de corte inferior a 10 mm s\u00e3o, em sua maioria, acionadas mecanicamente, e aquelas com espessura de corte superior a 10 mm s\u00e3o, em sua maioria, acionadas hidraulicamente.<\/p>\n\n\n\n

According to the orientation of the upper blade to the lower blade, the shearing machine can be divided into flat blade shearing and oblique blade shearing. When cutting with a flat blade, the sheet material touches the full length of the upper and lower cutting edges together, resulting in large shearing force, high power consumption, and large oscillation. However, the cutting quality is better, and the cut sheet is relatively straight without distortion. <\/p>\n\n\n\n

The transmission method of the flat-blade shearing machine is mostly mechanical transmission, which is mostly used for small shearing machines and thin plate cutting. Oblique blade cutting is a method of gradual shearing, so the instantaneous shearing scale is smaller than the width of the sheet. The cutting quality of the oblique blade is not as good as that of the flat blade, and there is distortion and deformation. However, the cutting force and energy consumption are smaller than flat-blade cutting, so it is used in large and medium-sized shearing machines.<\/p>\n\n\n\n

The shear is divided into the linear type and swing type according to the movement method of its knife holder. The straight-line structure is relatively simple (it looks like a guillotine gate, so it is also called a guillotine shearing machine), and it is convenient to manufacture. The blade has a rectangular cross-section and all four sides can be used as blades, so it is more durable. The knife holder of the swing beam shear moves around a fixed point during cutting. The advantage is that the conflict and wear between the upper and lower cutting blades are small, the blade deformation is small, and the cutting accuracy is high. <\/p>\n\n\n\n

However, the swing tool post accepts positive and negative alternating torque during the cutting process, so the width of the tool post cannot be too large. Therefore, the pendulum structure is mainly used for shears with a plate thickness greater than 6mm and a plate width not greater than 4000mm.<\/p>\n\n\n\n

After cutting, the shearing machine should be able to ensure the straightness and parallelism requirements of the cutting surface of the sheared sheet and minimize the distortion of the sheet to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, and the lower blade is fixed on the workbench. <\/p>\n\n\n\n

There is a supporting ball installed on the workbench to prevent the sheet from being scratched when sliding on it. The back gauge is used for positioning the plate, and the position is adjusted by the motor. The pressing cylinder is used to compress the sheet to prevent the sheet from moving during cutting. The guardrail is a safety device to prevent work-related accidents. The return journey generally relies on nitrogen, which is fast and has little impact.<\/p>\n\n\n\n

O came na extremidade esquerda do exc\u00eantrico aciona o \u00eambolo do tanque de \u00f3leo de prensagem para retornar a press\u00e3o ao p\u00e9 de prensagem e pressionar a folha antes de cortar. Ao retornar, o calcador \u00e9 devolvido pela for\u00e7a da mola.<\/p>\n\n\n\n

The hydraulic shearing machine is a new type of shearing machine that is different from the ordinary shearing machine. Because of the numerical control, its operation is more streamlined, and the efficiency of the workers is further improved. Numerical control hydraulic shearing machine refers to the technology that realizes the motion control of one shearing machine or multiple shearing machines with digital instructions composed of numbers, characters, and symbols. <\/p>\n\n\n\n

CNC hydraulic shears generally use general-purpose or special-purpose computers to achieve digital program control, which usually controls mechanical quantities such as position, angle, and speed, and switches related to the direction of mechanical energy flow. The production of CNC hydraulic shearing machines relies on the emergence of data carriers and binary data operations.<\/p>\n\n\n\n

Por muito tempo, o aperfei\u00e7oamento t\u00e9cnico das m\u00e1quinas de corte mec\u00e2nicas foi lento. Embora algumas empresas tenham feito melhorias no ajuste da folga da l\u00e2mina da m\u00e1quina de corte mec\u00e2nica e conseguido um ajuste r\u00e1pido, isso ainda causa mais danos do que benef\u00edcios. \u00c9 f\u00e1cil danificar a m\u00e1quina-ferramenta e isso ser\u00e1 eliminado em pouco tempo. A m\u00e1quina de corte mec\u00e2nica adota uma estrutura de embreagem tipo chave de resist\u00eancia e uma transmiss\u00e3o de engrenagem aberta e adota aparelhos el\u00e9tricos mais avan\u00e7ados (pedal, interruptor manual) para opera\u00e7\u00e3o, baixo ru\u00eddo, f\u00e1cil opera\u00e7\u00e3o e manuten\u00e7\u00e3o.
