目前,钢管零件的弯曲、胀形、缩口等成形类工序,已有成熟的冲压工艺方法来完成,而对钢管零件上的冲口、切口等分离工序,是否也可以用冲压的方法来完成呢?本文介绍的“钢管无凹模冲孔“工艺,回答了这个问题。“钢管无凹模冲孔”工艺,是联合收割机行业从国外引进的先进工艺方法之一。经过转化,已成功地用于批量生产。这说明钢管零件上的冲孔、切口等分离工序,同样可以用冲压的方法来完成。 At present, the steel pipe bending, bulging, shrinking and other forming processes, there are mature stamping process to complete, but on the pipe parts of the punching, incision and other separation processes, can also be used stamping method to complete This article describes the “steel pipe without die punching” process, to answer this question. “Pipe without die punching” process, is the combine harvester industry imported from abroad one of the advanced technology. After conversion, it has been successfully used in mass production. This shows the steel pipe parts punching, incision and other separation processes, the same method can be used to complete stamping.
