随着我国工业建设的飞跃发展,我厂生产的TD72型(目前已改为TD75型)通用固定式胶带输送机的需要量成倍地增长,1975年我厂的产量已达到590台,共32600米。过去我厂用普通机床加工输送机的零件,阻碍了生产的高速发展。如以年产600台胶带输送机,每台要用8只轴承座计算,每月便要生产400只以上的轴承座,因而经常出现金加工拖装配后腿的现象。为了改变这种状况,厂革委会和我们车间党支部在1973年下半年要求我组在短期内 With the rapid development of industrial construction in our country, the demand of TD72 (now changed to TD75) universal fixed belt conveyor produced by our factory has doubled. In 1975, the output of our factory has reached 590 sets, totally 32,600 Meter. In the past I used ordinary machine tools conveyor parts processing, hinder the rapid development of production. For example, with an annual output of 600 tape conveyors, each using eight bearing calculations, will have to produce more than 400 per month bearing, which often appear after the assembly of gold processing drag hitch with the phenomenon. In order to change this situation, the Plant Revolutionary Committee and our party branch in the second half of 1973 asked my group in the short term
