Stamping and welding integrated device and method for electric contact

Abstract

The invention discloses a stamping and welding integrated device and method for an electric contact. The device comprises a feeding mechanism, a cutting mechanism, a stamping mechanism, a conveying mechanism, a supporting component, a positioning component, an upper electrode and a lower electrode. The method comprises the steps that a material belt is stamped, a silver wire is cut off, the pre-stamped material belt and cut-off silver points are conveyed to a spot welding position, finally, power-on operation is carried out, and spot welding is finished. The cutting mechanism and the stampingmechanism process the silver wire and the material belt into the electric contact and the pre-stamped material belt, and the conveying mechanism conveys the electric contact and the stamped material belt to the spot welding position. The positioning mechanism enables the electric contact to make tight contact with the material belt. The stamping and welding integrated electric contact assembly with good welding quality and matched electric contact element sizes can be obtained. The stamping and welding integrated device and method are applicable to various electric contacts in complex shapes,the welding speed is greatly improved, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a forming device and method of an electric contact, in particular to a device and method for integrating stamping and welding of an electric contact, and finally obtains an integrated stamping and welding product. Background technique [0002] As the core component of the switching device, the electrical contact assembly is responsible for breaking and conducting the current. The quality of its welding has a great impact on the on-off capacity, anti-arc burning loss, service life and operation safety and reliability of the entire electrical appliance. play a decisive role. [0003] Electrical contacts often need to go through processes including stamping and feeding before welding, and then welded to form components. At present, many manufacturers independently produce and process each component, and multi-channel operations lead to problems of product size matching and secondary pollution, which in turn leads to a decrease in...
