我厂每年需要加工两千吨以上的硅钢片、用来冲制各种发电机、电动机的定、转子冲片。加工用的设备主要是压力机。以前压力机的上、下料主要依靠人工,工人操作危险、工作紧张、动作重复、人容易产生疲劳,曾发生过多次的人身事故。另外,用人工送料时,要把卷料剪切成板料以后再冲成冲片,这样材料的利用率较低,也造成了浪费。根据以上的情况我们进行了分析、调查研究,决定采用卷料送料装置,并于1979年3月试制成功(见图1)。几个月来,用它已加工冲片五十余万片,受到了工人们的欢迎,效果显著。
I plant each year need to process more than two thousand tons of silicon steel sheet, used to punch all kinds of generators, motor stator and rotor film. Processing equipment is mainly press. Previous press of the upper and lower material mainly rely on labor, workers dangerous operation, work stress, repetitive movements, people prone to fatigue, there have been many personal accidents. In addition, when using manual feeding, it is necessary to cut the material into a sheet and then punched into a sheet, so that the utilization of the material is low, which also results in waste. According to the above situation, we conducted an analysis, investigation and study, decided to use the coil material feeding device, and in March 1979 trial success (see Figure 1). In the past few months, it has processed more than 500,000 pieces of punched tablets and was welcomed by the workers with remarkable results.
