检验成品或半成品钢丝机械性能(拉伸、弯曲、扭转)的试样,过去各有关厂都是人工用手矫直后,再送到专门的剪切机上剪取,劳动强度大,效率低。一九六三年五月份,青岛钢厂钢丝绳分厂试制成功一台能连续矫直和切断0.6～1.2毫米直径钢丝的纲丝矫直、切断机,经过一年多的试验,证明用机械矫直比用手工矫直提高效率三倍半, Test the finished or semi-finished steel wire mechanical properties (tensile, bending, torsion) of the sample, in the past all the relevant plants are manually hand straightening, and then sent to a special shear cut, labor-intensive, low efficiency. In May 1963, the pilot plant of Qingdao Steel Wire Rope Factory successfully trial-produced a wire straightening and cutting machine capable of continuously straightening and cutting 0.6-1.2 mm diameter steel wire. After more than one year of trial, it was proved that mechanical straightening Directly compared with manual straightening to improve efficiency three and a half,
