1983年3月,美国Warner&Swasey公司在Wiedemann的制造厂研制成功一台Quantum 2000型冲床。该厂生产系列化的CNC冲床产品,吨位从16.5吨(Ceutrum 1000型)至60吨(W6050型),它们代表了冲压机床的全部更新技术,其中三项重要改革使目前的生产率提高一倍以上。第一项改革:采用一套可拆换的冲压模具,见附图,代替了传统的固定式转塔(调换冲模的转盘)。可拆换的模具在前一套模具正在加工时就可在机外将下一个工件的冲头和模具装上待用,因而节省了停机工
March 1983, the United States Warner & Swasey Wiedemann’s manufacturing plant in the successful development of a Quantum 2000 punch. The plant produces serialized CNC punch presses with capacities ranging from 16.5 tonnes (Ceutrum 1000) to 60 tonnes (W6050), representing the complete update of press machines, three of which have resulted in more than doubling current productivity . The first reform: the use of a set of removable stamping die, see the accompanying drawings, instead of the traditional fixed turret (change the die turntable). Removable mold The first set of molds are ready for use on the next workpiece punch and mold while the mold is being machined, saving downtime
