Abstract

The invention discloses a stamping and welding integrated device and method for electric contacts. The device comprises: a feeding mechanism, a material cutting mechanism, a stamping mechanism, a transmission mechanism, a supporting part, a positioning part, an upper electrode and a lower electrode. The method is as follows: first punch the material strip, cut off the silver wire, then transfer the pre-punched material strip and the cut silver dots to the spot welding position, and finally energize to complete the spot welding, wherein the material cutting mechanism and the stamping mechanism transfer the silver wire to the spot welding position. Wire and material strips are processed into electrical contacts and pre-punched material strips. The transfer mechanism transfers the electrical contacts and the punched strip to the spot welding position. The positioning mechanism makes the electric contact closely contact with the strip. The present invention can obtain a stamped and welded integrated electric contact assembly with excellent welding quality and matching dimensions of the components of the electric contact. The method and device involved in the present invention are suitable for various electric contacts with complex shapes, and the welding speed is greatly improved. Production costs are 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...
