多用气压打孔器的创新设计

The Innovation Design of Multi-purpose Air Pressure Hole Punch

金属加工领域中,现有的打孔器在加工高硬度小尺寸的胚件时,冲孔的边角容易卷边,并且仅是模刀可拆卸,而连接柱头不能拆卸,加工不便利。为解决现打孔器所存在的缺陷,创新设计了一种多用气压打孔器。新型打孔器采用可更换的连接柱头和液压接嘴阵列,可以把毛刺控制在材料厚度的1%~3%内,提高生产效率。

In the field of metal processing, in processing high hardness of the small size of the embryo,the existing punch is not convenient.To solve the existing problems,a new multi-purpose pressure punch is designed.New punch using replaceable connected stigma and hydraulic nozzle array can control the burr fin in 1%~3% of material thickness and improve production efficiency.
