Electro-hydraulic control multi-cylinder linkage bending machine

Abstract

The invention discloses an electro-hydraulic control multi-cylinder linkage bending machine which mainly comprises oil cylinders, wall plates, connecting beams, an oil tank, sliding blocks, a workbench, a mould, a hydraulic system, an electrical system, a numerical control system and the like. The single equipment comprises one hydraulic assembly and two synchronous blocks; two grating scales are respectively arranged on two sides of the machine; the synchronous operation of the sliding blocks is detected, data is fed back to the numerical control system, and four oil cylinders are controlled by servo valves to bend synchronously downwards. Due to the adoption of the device, the cost of the materials needed by the synchronous bending of two cylinders is saved greatly, the product bending effect is improved, and the difficulty of purchasing the raw materials (steel) is reduced.

Description

technical field [0001] The invention relates to the field of bending machines, in particular to an electro-hydraulic control multi-cylinder linkage bending machine. Background technique [0002] Bending machines are used to bend and shape sheet metal materials, and have the characteristics of economy, safety, high efficiency, energy saving, and environmental protection. Therefore, countries all over the world attach great importance to the development of bending machines. At present, bending machines at home and abroad The machine generally adopts two-cylinder bending, and sometimes when the length is as large as ten meters, it adopts two-machine four-cylinder linkage bending, but because the length is too long and the span of the two wall panels is too large, the upper and lower sides of the workbench and the slider are changed. If it is too large, it will also cause the middle of the slider to bend back and forth, which often fails to meet the requirements for the angu...

If it is too large, it will also cause the middle of the slider to bend back and forth, and often the angular size and straightness of the processed sheet cannot meet the requirements
