针对某机载设备控制用接触组在生产过程中报废量大、合格率低的问题,进行深入研究,并找到问题的主要原因。提出在接触组关键零件生产过程中,降低簧片硬度值、增加热处理时效及增加装配粘接工艺等方法。经过相关改进及验证试验,批次生产证明该工艺技术的可靠性和有效性。 Aiming at the problem that a contact group for control of a certain airborne equipment has a large amount of scrap and a low pass rate in the production process, it conducts further studies and finds out the main reasons for the problem. Proposed in the contact group of key parts production process, reducing the reed hardness value, increase heat treatment aging and increase the assembly bonding process. After the related improvement and verification test, the batch production proves the reliability and effectiveness of the process technology.
