我厂在北京工业学院和北京齿轮厂等单位大力协助下,于1970年制造出一台自动回程式快放油高速锻锤。三年来,经过多种试验和应力测定以及生产检验,证明性能较好,基本上达到了原设计要求,可以完成打击、悬锤、细调、回程、自动回程、顶出等动作,解决了弹跳问题。仅1972年生产的一种锻件就进行中压 With the assistance of the Beijing Institute of Technology and the Beijing Gear Factory, our factory produced a self-contained fast-displacement high-speed forging hammer in 1970. In the past three years, various tests, stress tests, and production inspections have proven to be of better performance. They basically meet the original design requirements and can complete actions such as striking, overhanging, fine adjustment, return stroke, automatic return, and ejection, and solve bouncing. problem. Only a forging produced in 1972 was used for medium pressure
