一种USB接口金属外壳的制造方法及制造设备
Abstract:
本发明实施例提供一种USB接口金属外壳的制造方法及其制造设备，其中，USB接口金属外壳的制造方法包括步骤：将扁状毛坯管上料至下模(S100)；第一上模与下模合模，对所述毛坯管底部进行胀管成型(S110)；第二上模与下模合模，对所述毛坯管顶部端口进行缩口倒角(S120)；第三上模与下模合模，对所述毛坯管进行修正，以获得最终的USB接口金属外壳成品(S130)。本发明提供的USB接口金属外壳的制造方法，通过三次合模过程，使USB接口金属外壳在一个下模工位上分别与三个上模合模完成胀管、缩口倒角以及整形工艺，可一次性得到满足尺寸要求的USB数据线接口金属外壳，其工艺简单，USB接口金属外壳倒圆角处的材料收缩均匀，成品尺寸精度稳定。
Abstract(English):

The present disclosure provides a manufacturing method and a manufacturing apparatus for an USB interface metal casing. The manufacturing method for an USB interface metal casing includes: feeding a flat-shaped pipe blank to a lower mold (S100); closing a first upper mold and the lower mold, and performing pipe-expansion forming to a bottom of the pipe blank (S110); closing a second upper mold and the lower mold, and performing necking and chamfering to a top port of the pipe blank (S120); and closing a third upper mold and the lower mold, and modifying the pipe blankto obtain a final finished product of the USB interface metal casing (S130).
