空心矩形管标记制造工艺与模具设计

Manufacturing process and tooling design for hollow rectanglar tube mark

针对空心矩形管因自身强度不足,在标记压印过程中易变形、压印字迹不清晰等问题,结合空心矩形管内部为空心的结构特点,分析了空心矩形管标记压印成形工艺。提出采用斜楔自锁模具结构,并进行了模具设计以及制造验证,实现了空心矩形管标记的制造,保证了标记压印成形并达到工艺要求,保证了产品生产顺利进行。

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 imprinting. 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.
