Abstract

The invention discloses an annular rolling precise welding device. The annular rolling precise welding device comprises a rolling resistance welding structure, and the rolling resistance welding structure comprises a lower welding wheel on the lower portion and an upper welding wheel located over the lower welding wheel; the lower welding wheel is fixedly mounted, and an air cylinder is arranged above the upper welding wheel in an abutting manner; the upper welding wheel is driven by the air cylinder to vertically displace, and the diameter of the upper welding wheel is equal to that of the lower welding wheel; and a rotatable product fixing seat is fixedly mounted right ahead of the lower welding wheel. A welding position of a product is even and free of gap, and the product sealing performance is obviously improved.

Description

technical field [0001] The invention relates to a welding device, in particular to an annular rolling precision welding device. Background technique [0002] Sanitary drainage system products with bosses have very high requirements for welding parts and internal sealing. The traditional process uses spot welding for welding, which has low production efficiency and high labor intensity, and the uneven welding of the product will produce small gaps, resulting in reduced sealing performance and unstable product quality. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an annular rolling precision welding device, which can make the welded part of the product uniform and seamless, and significantly improve the sealing performance of the product. [0004] In order to solve the problems of the technologies described above, a technical solution adopted in the present invention is: [0005] An annular rolling precision ...
