Abstract

The invention discloses a connecting piece with the local hardening technology. The connecting piece comprises a fixed base and a rectangular frame, the rectangular frame is arranged at the upper endof the fixed base, and integrated stretching forming is adopted between the rectangular frame and the fixed base; bent elastic parts are symmetrically arranged in the middles of the two short sides ofthe rectangular frame, each bent elastic part is provided with a protruding part protruding towards the inside of the rectangular frame, and a V-shaped positioning groove is formed in the top of eachbent elastic part. The invention also discloses a manufacturing technology for manufacturing the connecting piece with the local hardening technology; the technology includes the following steps that1, the rectangular frame is stretched and formed; 2, materials are thinned, and local hardening is carried out; 3, waste materials of a local hardening area are cut off; 4, waste materials before theedges of the rectangular frame are turned are cut off; 5, turned edges are formed; By means of the connecting piece with the local hardening technology and the manufacturing technology thereof in themode, the traditional heavy-and-complicated and low-efficiency technology for enabling a frame body to be in rivet weld connection with the elastic part can be avoided, the stability and the reliability of the product quality are greatly improved.

Description

technical field [0001] The invention relates to the technical field of connector structures for automotive electronics and large-scale mechanical equipment, in particular to a connector utilizing a local hardening process and a manufacturing process thereof. Background technique [0002] For some special connectors of automotive electronics and large mechanical equipment, due to functional requirements, conventional riveting and welding processes are usually used to rivet or weld the thick material body of the precision connector and the relatively thin elastic part. However, the traditional riveting / welding connection process is complicated, inefficient and unstable, and has a high defect rate. The riveting and welding process has a great impact on the product itself, and often leads to substandard mechanical properties and uneven overall process performance. Therefore, a new process structure is urgently needed to improve the precision, stability and reliability of connect...
