自动冲压线的生产率可达2000、4000甚至50000件/小时。生产率越高,辅助时间的多少越显得重要。更换卷料时的带料喂入装置、快速换模装置、成品的自动卸出装置和堆垛装置,对于生产效果而言,和压力机的行程次数具有同等重要的意义。从送入原材料到冲出成品,整个加工过程连成生产线,实现连续加工,这样的自动线目前还不是很多。并且必须承认,这种自动线并不到处都是经济的。下面为两条自动线的例子。一条是生产书架零件的冲压线。具有塑料
Automatic stamping line productivity up to 2000,4000 or even 50,000 pieces / hour. The higher the productivity, the more the amount of auxiliary time is more important. Strip feeding, quick changeover, automatic unloading and stacking of the finished product at the time of coil change are of equal significance to the number of trips made by the press for production results. From the incoming raw materials to the finished product, the entire process even into a production line, to achieve continuous processing, such an automatic line is not much. And it must be admitted that such automated lines are not economical everywhere. The following is an example of two automatic lines. One is the production of bookshelf parts of the press line. With plastic
