我厂冷镦冲头过去是车削加工,加工工艺复杂,生产效率低,产品质量差。广大革命职工为了改变这一生产落后面貌,认真学习伟大领袖毛主席关于“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上”的教导,根据我厂的具体情况,将一台90吨手动榨油机改装成机动油压机。在此设备上进行冷镦冲头型腔冷挤压,其中有半圆头螺钉、半圆头铆钉、圆头螺钉、球面圆柱头螺钉、六角螺栓、方头螺栓、圆柱头内六角螺钉、半圆 Cold stamping plant in the past I was turning, complex processing technology, low productivity, poor product quality. In order to change the backwardness of this production and extensively study the great leaders, Chairman Mao said: “In the context of the struggle for production and scientific experiments, mankind is always evolving. Nature is always constantly evolving and will never stop at a certain level On the ”teaching, according to the specific circumstances of our plant, a 90-ton manual oil press into mobile hydraulic press. In this equipment for cold heading punch cold extrusion, which have a half round head screws, round head rivets, round head screws, spherical head cap screws, hex bolts, square head bolts, cylindrical head cap screws, semicircles
