预变形器是消涂钢丝绳和股中存在残余应力的主要方法,是提高钢丝绳的质量、延长钢丝绳使用寿命的重要环节。目前在国内使用预变形器有二种,即“立式”的和“卧式”的,我广现发展新型的第三种变形器“螺旋式”,经过二个多月的试验,已取得成功,现将试验情况介绍如下。 1.目前使用的卧式及立式变形器 (1)卧式变形器是最早研究和应用的,它的结构是(?)锥形体的斜面上,按照变形量的要求,固定地安装滑轮,股绳通过滑轮而产生预变形。它的优点是操作方便、生产的产品质量稳定,可以减轻工人的劳动强度、但也有缺点,即滑轮之间距离不能多 Predeformer is the main method of eliminating residual stress in wire rope and strands, and is an important part of improving the quality of wire rope and prolonging the service life of wire rope. At present, there are two types of pre-deformer used domestically, that is, “vertical” and “horizontal.” I have now developed a new type of “spiral”, a third type of deformer. After more than two months of tests, Success, the test is introduced below. 1. Currently used horizontal and vertical deform (1) horizontal deformer is the earliest research and application, its structure is (?) Cone on the slope, in accordance with the requirements of deformation, the fixed installation of pulleys, The rope is pre-deformed by the pulley. Its advantage is easy to operate, the quality of the products produced is stable, which can reduce the labor intensity of the workers, but also has the disadvantage that the distance between the pulleys can not be more
