Girth welding device and girth welding method for tubeless engineering rims

Abstract

The invention discloses a girth welding device and girth welding method for tubeless engineering rims. The girth welding device comprises a base and four electric welding devices, each electric welding device comprises a welding gun, a rim supporting seat is arranged on the base, a welding position is arranged on the rim supporting seat, a liftable electric conduction pressing wheel is arranged above the welding position, and the electric conduction pressing wheel is electrically connected with all the electric welding devices. The girth welding method comprises the steps of pre-welding, feeding, welding gun in-place, girth welding and discharging. According to the girth welding device and girth welding method for the tubeless engineering rim, a simultaneous staggered girth welding mode is adopted for welding, the welding efficiency of the tubeless engineering rim is improved, the problem of the simultaneous welding process of multi-section workpieces is solved, and the welding quality of the rim can be effectively ensured. Feeding and discharging of the girth welding device are convenient and fast, and the manual dependence degree in the welding process is further reduced.

Description

technical field [0001] The invention belongs to the technical field of wheel rim production, and in particular relates to ring welding equipment and a ring welding method for tubeless engineering wheel rims. Background technique [0002] The tubeless engineering rim is composed of inner rim, intermediate connecting cylinder and groove ring welded in sequence. One side of the inner rim is expanded to form the inner rim, and the other side is welded with the intermediate connecting cylinder. The groove ring is provided with an annular groove. During the welding process, the joints between the inner rim and the intermediate connecting cylinder, and the joint between the intermediate connecting cylinder and the groove ring need to be welded on the inside and outside, so if manual welding is used, it is necessary to perform four rounds of welding in succession. It can be completed, but the welding efficiency is low, it takes a long time, the labor cost is high, and the welding qu...

AI Technical Summary

Problems solved by technology

During the welding process, the joints between the inner rim and the intermediate connecting cylinder, and the joint between the intermediate connecting cylinder and the groove ring need to be welded on the inside and outside, so if manual welding is used, it is necessary to perform four rounds of welding in succession. It can be completed, but the welding efficiency is low, it takes a long time, the labor cost is high, and the welding quality cannot be guaranteed

Using an automated welding robot for welding can save labor, improve welding efficiency and ensure welding quality, but it also requires four rounds of welding to complete the welding

Whether it is manual welding or automated robot welding, the welding process needs to complete four rounds of welding successively. During this process, the position and state of the inner rim, intermediate connecting cylinder and groove ring need to be strictly controlled, otherwise the welding quality will be easily affected and the operation will be difficult.
