两根互绕扁螺旋钢丝的剪切机构设计

Shearing mechanism design of two mutually twisted flat screw wires

两根互绕扁螺旋钢丝的剪切作业是菱形金属网编织机设计中的关键一环。在此 ,基于左右两把剪刀的剪切平面相对于主传动平面成± 45° ,以及与变结构相结合的设计理念 ,设计出了两根互绕扁螺旋钢丝的剪切机构。该种剪切机构具有力放大功能 。

The shearing work of two mutually twisted flat screw wires is a key link in the design of rhombic metal mesh weaving machines. At here, based upon designing idea of the shearing planes of left and right two shears are at ±45°with respect to main transmission plane and the combination with changeable structure, the shearing mechanism of two mutually twisted flat screw wires was designed. This kind of shearing mechanism possesses force-magnifying function, and the comparatively larger relative error of flat screw wire will not affect the shearing work.
