Problems solved by technology

The disadvantages of this welding method are: the melting of the welding wire and poor adhesion to the base metal during welding will inevitably reduce the welding strength, affect the welding effect, and reduce the welding quality. The space inside the tube is narrowed, which affects the fluidity of the medium in the tube

Embodiment Construction

[0012] The pipe flanging device comprises a fixed deck 1, a frame 13, an upper power gun slip 7, a lower power gun slip 12, a drill bit 5, a gear transmission mechanism, and a power gun 26. The fixed card base 1 is provided with a seat groove 2, and its seat groove 2 is connected with the fixed card base 1 to form an integral structure. The fixed slips 16 and the movable slips 15 are housed in the seat groove 2, and two belts are installed on the seat groove 2 sides. A vertical plate 3 with three threaded holes, its vertical plate 3 is fixedly connected on the seat groove 2, the long lead screw 19 and the short lead screw 18 are respectively screwed into the two threaded holes through the handle 4, and are pressed against the movable slips 15, the seat The other side of the groove 2 is loaded with pad iron 17 with different thickness of the slip opening, so that the fixed slip 16 is fixed against the pad iron 17, the lower power gun slip 12 is fixedly connected to the frame 13,...

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 steel pipes into groove form butt joints, and after tack welding, fill the butt welds with welding wire. The disadvantages of this welding method are: the melting of the welding wire and poor adhesion to the base metal during welding will inevitably reduce the welding strength, affect the welding effect, and reduce the welding quality. The space inside the tube is narrowed, which affects the fluidity of the medium in the tube. (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 saves the welding wire filling process by flanging, improves the welding strength of the pipe, overcomes the obvious inward protr...
