Fluid conduction branch pipe and main pipe edge curling and welding equipment

Abstract

The invention discloses fluid conduction branch pipe and main pipe edge curling and welding equipment. The equipment comprises a main pipe and a branch pipe and further comprises a supporting mechanism, a clamping mechanism, a moving mechanism, an edge curling mechanism and a welding mechanism. The clamping mechanism is fixedly installed on the upper surface of the supporting mechanism, the moving mechanism is also arranged on the supporting mechanism, the edge curling mechanism is arranged on the upper surface of the supporting mechanism and connected with the moving mechanism, and the welding mechanism is arranged on the upper surface of the supporting mechanism and is connected with the moving mechanism. According to equipment, the edge curling mechanism and the welding mechanism are arranged on the supporting mechanism, so that the equipment integrates the edge curling function and the welding function, the main pipe and the branch pipe can be directly welded without replacing or installing a welding tool after edge curling is conducted on the main pipe, and the working efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of crimping welding. Specifically, it is a crimping welding equipment for fluid conduction branch pipes and main pipes. Background technique [0002] Generally, the main pipes of the pipelines used for fluid conduction are metal pipes, and there are often multiple holes on the main pipes to connect the branch pipes to divert the fluid. Therefore, in order to improve the welding strength, it is required to perform inner crimping or outer crimping on the edge of the hole. Among them, the water flow channel of the main pipe with the inner crimp is not smooth due to the inner crimp, which increases the resistance of the water circulation; while the circulation water cavity of the main pipe with the outer crimp has a smoother water flow channel, but the crimping edge The process is more complicated, and the traditional process of inner mold and outer mold is often used, and the inner mold has to be inserted int...

Among them, the water flow channel of the main pipe with internal crimping is not smooth due to the internal crimping, which increases the resistance of water circulation; while the water flow channel of the main pipe with external crimping is relatively smooth, but the crimping The process is relatively complicated, and the traditional process of inner mold and outer mold is often used, and the inner mold must be inserted into the dry pipe, so it is difficult to improve the production efficiency, and the existing welding method has a small welding area and is not strong enough to be easily eroded by liquid
