摘　　要：针对不旋转钢丝绳的生产要求,对可调式锥型预变形器进行结构和工艺设计。辊轮材质选择GCr15,轴采用50Cr。以18×7+FC-7.15 mm钢丝绳为例,对可调式锥型预变形器进行预变形器角度、前盘锥头处直径、最小中心距、中盘和后盘锥头处直径、辊轮尺寸等参数进行计算。股绳压弯量大小通过滑块装置调整,各股变形量一致,从而保证钢丝绳的捻制质量,提高了工作效率。预变形器经试用,捻制出符合标准的18×7类不旋转钢丝绳。According to production requirements of non-rotating wire ropes,structure and process design of adjustable cone pre-deformer is carried out.The material of roller is GCr15,and shaft is 50Cr.Taking 18×7+FC-7.15 wire rope as an example,perform pre-deformer angle,the diameter of cone head of front disc,minimum center distance,diameter of cone head of middle disc and back disc,and roll wheel size and other parameters are calculated.Bending amount of strand is adjusted by slider device,and deformation of each strand is same,thereby ensuring lay quality of wire rope and improving work efficiency.The pre-deformer has been tried and lay a standard 18×7 non-rotating wire rope.
