为了提高钢丝绳的寿命,提高其许用负荷能力,减轻钢丝绳重量,人们在降低股内丝间接触应力上想了很多很好办法。其中之一是在工艺上比较简单的办法是拔制法,即将拧好的线接触普通绳股,再经一道拉模拔制加工,使丝表面塑性变形达到丝问实现面接触的加工方 In order to improve the life of wire rope, improve its allowable load capacity, reduce the weight of wire rope, people think of a lot of good ways to reduce the contact stress between the wire. One of the simplest methods in the process is the drawing method, which is about to screw a good line of contact ordinary rope shares, and then a drawing process, so that the surface of the wire to achieve plastic deformation of silk asked to achieve surface contact with the processing side
