Contact welding forming process and automatic processing equipment

Abstract

The invention discloses a contact welding molding process; the contact welding molding process consists of primary bending, welding and secondary bending; firstly, the two ends of a contact piece can be bent to form a fixed bending part and a striking arc bending part corresponding to the middle part of the contact piece; then, a silver contact and a welding part are welded and fixed; and finally, the fixed bending part and / or the striking arc bending part of the contact piece are continuously bent to form arc structures. A contact loading bending device, a welding device and a contact unloading bending device are correspondingly encircled on the edge of an index plate of automatic processing equipment for contact welding molding; and the contact loading bending device can perform the primary bending for the contact piece and transfer the primarily bent contact piece to the welding device and the contact unloading bending device in sequence through the index plate so as to correspondingly finish the welding of the silver contact and the secondary bending procedure of the contact piece. The invention provides a contact welding molding process and automatic processing equipment with stable welding process, high product pass percent and high automation degree.

Description

technical field [0001] The invention relates to the field of welding processing, in particular to a contact welding forming process and automatic processing equipment. Background technique [0002] At present, the welding of the contact and the silver contact is carried out by a manual welding machine. The production process is as follows. Heating and melting the whole product for welding destroys the material properties of the whole product, softens the product, and reduces the service life. At the same time, it takes 3 to 5 seconds for the overall heating until the flux melts, which makes the welding time longer and reduces the stability of welding. sex. Some of the existing welding processes also use spot welding or brazing. Although the work efficiency is improved and the overall material of the product is also improved, the silver contact at the welding point of the product will be cracked when the product is bent and formed after welding. , causing cracks and deforma...

[0002] At present, the welding of the contact and the silver contact is carried out by a manual welding machine. The production process is as follows. Heating and melting the whole product for welding destroys the material properties of the whole product, softens the product, and reduces the service life.

Some of the existing welding processes also use spot welding or brazing. Although the work efficiency is improved and the overall material of the product is also improved, the silver contact at the welding point of the product will be cracked when the product is bent and formed after welding. , resulting in cracks and deformation of the silver contacts, which reduces the stability of the welding process and the pass rate of welding products
