Problems solved by technology

[0002] For high-toughness steel pipes such as stainless steel pipes, the traditional welding method is to process two butt steel pipes into groove form butt joints. After tack welding, the butt welds are then filled with welding wire. The disadvantage of this welding method is that the welding wire The poor adhesion between melting and base metal will inevitably reduce the welding strength, affect the welding effect, reduce the welding quality, and the pipe wall at the welding place will be thickened, the diameter will be reduced, and the space inside the pipe will be narrowed, which will affect the medium flow in the pipe

Abstract

A pipe flanging machine is composed of machine frame, fixture with fixed jaws and movable jaws, vertical plate with two leading screws, power gun, upper and lower fixing jaws for said power gun, engaged drive and driven gears, and exchangeable drill bit and punch head for power gun in order to machine pipe end and flange it.

Description

(1) Technical field [0001] The invention relates to a pipe flanging device for processing pipe mouth flanging during steel pipe welding. (2) Background technology [0002] For high-toughness steel pipes such as stainless steel pipes, traditional welding is to process two butt-joined steel pipes into a grooved butt joint. After tack welding, fill the butt weld with welding wire. The disadvantage of this welding method is that the welding wire is used during welding. The poor adherence of melting and base metal will inevitably reduce the welding strength, affect the welding effect, and reduce the welding quality. In addition, the pipe wall at the weld is thickened, the diameter is reduced, and the inner space of the pipe is narrowed, which affects the flow of the medium in the pipe. (3) Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pipe flanging butt welding, which eliminates the process of filling welding wire by fl...
