我厂生产的内燃机上有很多锻件,长期以来都是在空气锤或夹板锤上进行胎模锻造。锻模重的有二百多公斤,轻的也有几十公斤。全靠人抬手提,劳动强度大,不安全,远远跟不上生产不断发展的需要。锻工车间职工遵照伟大领袖毛主席关于“独立自主、自力更生”的教导,发扬了敢想敢干的革命精神,大搞技术革新,从而实现了自由锻锤模锻化。从1966年至今七年的使用情况证明效果良好,现简介于下,供同志们参考。一、锻模结构(见图):上下模燕尾和空气锤上下砧燕尾相同,为了节省模具钢和便于调整模具,将模块高度减小,增设一个垫砧,垫砧燕尾槽二侧各放大2 I plant a lot of forging on the engine, for a long time in the air hammer or splint hammer on the tire forging. Die forging more than 200 kilograms, there are also light dozens of kilograms. Rely on people to raise their hands, labor-intensive, insecure, far behind the production needs of the continuous development. The workers in the forging workshop followed the teachings of Chairman Mao, the great leader, on “independence and self-reliance,” carried forward the revolutionary spirit of daring to think and dared to do a great deal of technological innovations, and achieved free forging. The use of seven years from 1966 to the present has proved to be effective and is now available for reference by comrades. First, the forging structure (see photo): upper and lower mold dovetail and air hammer dovetail antelope the same, in order to save die steel and easy to adjust the mold, the module height is reduced, an additional pad anvil, pad anvil dovetail on both sides of each amplification 2
