冲床具有效率高、省料等优点,所以在机械加工行业中被广泛地采用。但由于冲床本身的性质所决定,冲床操作者出事故的机会比其它机床出事故的机会要多。冲床所出的事故主要是操作者的手或手指被冲头压伤、压坏致残的人身事故。为了减少这类事故的发生,可采用多工位组合模具、自动送料、机械手、程序控制冲床等。但这些措施都只适用于单一的、品种少、批量大、不经常更换模具或设备专用的厂家。而作为多品种、批量小,经常更换模 Punch with high efficiency, save the advantages of materials, so in the machining industry is widely used. However, due to the nature of the punch itself, punching machine operators have more chances of accidents than other machine tools. Punch the accident is mainly caused by the operator’s hand or fingers crushed by punching, crushing crippled personal accident. In order to reduce the occurrence of such accidents, multi-station combination mold, automatic feeding, manipulator, program controlled punch press and the like can be adopted. However, these measures are only applicable to a single, less variety, bulk, often do not replace the mold or equipment manufacturers. As a multi-species, small batch, often changing mode
