圆片冲头零件激光淬火工艺实验

对药物冲头零件采用激光淬火及其淬火后机械加工工艺参数优化进行了综合研究.用2kW CO2激光器对医药系统的4mm～5.5mm圆片冲头的工作面进行激光淬火,淬火深度为0.7mm,其主要组织为细小马氏体.结果表明,零件的强度、韧性、耐磨性、抗冲击性、使用寿命均有提高.介绍了利用激光淬火改善材料组织、减少变截面应力产生、防止机械加工时裂纹的产生、提高零件综合机械性能的方法.

Laser hardening process for tablet punch pin

Laser hardening process and machining process parameters for tablet punch pin have been studied.A 2kW CO 2 laser is used to harden the punch pin for a pharmaceutical factory.Through laser hardening,petty martensite has obtained with a depth of 0.7mm.Results show that the working surface of the punch pin hardened by laser has higher hardness and strength,abrasive resistance,impact resistance and longer life.This paper introduces the laser hardening process to improve material organization,reduce stress on variable sections,prevent crack produced in the process of manufacture and improve the combined mechanical performances of the punch pin.
