简介：某往复式压缩机活塞杆在研磨处理过程中因尺寸超差导致失效。采用断口宏观检查、化学成分分析、金相检验、硬度检测等方法对活塞杆的失效原因进行分析。结果表明：活塞杆失效主要是由于预备热处理工艺不当形成的上贝氏体回火组织和氮化处理过程中形成的严重脉状组织造成的;根据分析结果对工艺顺序、淬火温度、淬火保温时间和氮化工艺进行调整,并对工艺改进后得到的产品进行检测,检测结果显示产品性能指标符合设计要求,工艺改进后可有效避免活塞杆失效的发生。

简介：新能源汽车是未来汽车发展的方向．作为汽车空调压缩机的重要零部件——轴承座的合理设计和经济制造，对确保压缩机性能和降低成本具有十分重要的意义。在汽车空调压缩机里，轴承座与高速运转的转轴和涡旋盘相互配合．在复杂应力状态和高应力值之下．高速而长时间地工作，对其有很高的性能要求。传统的重力铸造生产效率较低，易产生气孔、缩松等内部缺陷．随着新能源汽车销量日益增加．显然已经不能满足生产要求。本文采取以锻代铸的方法．用DEFORM-3D对新能源汽车空调压缩机轴承座成形进行数值模拟，分析成形过程中金属流动规律，提出了预锻制坯．然后背压力闭塞式模锻终成形的锻造工艺，不仅可以改善轴承座的机械性能，提高材料利用率．还能大大提高生产效率。
