Abstract: Aimed at the problem that the hollow rectangular tube is deformed due to the lack of its own strength, and the imprinting is not clear during the process of marking imprint ing. The thesis analyzes the forming process of mark-stamping of hollow rectangular tube according to the structure characteristics. It is proposed to adopt wedge self-locking mould structure. Also the design and manufacturing of mould is completed for verifying. Thus the manufacturing of mark-forming stamp on hollow rectangular tube is achieved,it ensures the mark-stamping process to the technological requirement and the production is carried out smoothly.

用压印工艺时，因自身强度不足，造成空心矩形
0引言
随着市场对产品制造过程可追溯潮要求的日益提高，需要在产品或部件上留下生产厂商、生产日期、序列号等可追溯的标记，一些关键零部件要求加工伴随产品全生命周期的永久性标记。现可追溯标记制造普遍采用刻印机刻印工艺，其深度通常小于0.3mm；当深度要求大于 0.3mm时，需要采用压印工艺。空心矩形管采
