上海无线电八厂的产品中,冲压件的数量较大,而且品种多、批量小、零件要求高。面对这种情况、该厂广大工人在厂党委的领导下,遵照毛主席关于“打破洋框框,走自己工业发展道路”的教导,自力更生,大搞技术革新,向落后的模具开刀,向冲床“老虎口”进军,在制造出带料、丝料的自动模具基础上,又试制成功十台微型联合冲裁机,为薄料零件的冲制提供了新方法,使银镁镍簧片的生产实现了机械化,减轻了劳动强度,提高了生产效率。革新前后的对比见下表。微型联合冲裁机是台式流水线,一机内由3～4道工序组成。具有体积小的特点,原来的簧片加工包括四道工序:(1)落料,(2)打
The products of Shanghai Radio Eight Factory have a large number of stamping parts, and they have many varieties, small batches, and high parts requirements. Faced with this situation, the majority of workers in the factory, under the leadership of the factory party committee, followed Chairman Mao’s guidance on “breaking down the foreign framework and taking the path of its own industrial development”, self-reliant, engaged in technological innovation, and started to lag behind the molds. “Tiger’s mouth” marched on and based on the automatic molds for the production of tapes and yarns, ten mini-united punching machines were successfully tested, providing a new method for punching thin-walled parts, making silver-magnesium nickel reeds Production achieved mechanization, reduced labor intensity, and increased production efficiency. The comparison before and after the innovation is shown in the table below. The micro joint punching machine is a bench-top assembly line. It consists of 3 to 4 processes in one machine. With the characteristics of small size, the original reed processing includes four processes: (1) blanking, (2) playing
