90-degree elbow and flange butt welding semi-automatic equipment

Abstract

The invention relates to 90-degree elbow and flange butt welding semi-automatic equipment. The 90-degree elbow and flange butt welding semi-automatic equipment mainly solves the problems that when flanges are welded to a flange type 90-degree elbow in the prior art, the production efficiency is low, and the machining quality is difficult to guarantee. The 90-degree elbow and flange butt welding semi-automatic equipment is characterized in that an elbow rotary clamp (2) is arranged on one side of a clamp seat (105), an electromagnet (204) is arranged below a groove (203), an indexing air cylinder (205) is arranged on a supporting seat (202), and a flange rotary hydraulic cylinder (110) and an elbow rotary hydraulic cylinder (6) can synchronously run. According to the 90-degree elbow and flange butt welding semi-automatic equipment, a flange automatic alignment conveying device and the elbow rotary clamp are adopted to clamp the flanges and the elbow correspondingly and then enable the flanges and the elbow to correspond to each other, the flanges and the elbow can synchronously rotate, butt welding between the flanges and the elbow is realized by utilizing an automatic welding gun,the positions of bolt holes in all the flanges can be kept consistent through the flange automatic alignment conveying device, and the characteristics of high production efficiency and good welding quality are achieved.

Description

technical field [0001] The invention relates to a pipe fitting processing equipment, in particular to a semi-automatic equipment for butt welding of a 90-degree elbow and a flange. Background technique [0002] Elbow is a commonly used pipe fitting, which is mainly used for the connection of pipe bends, of which 90 degree elbow is the most common one. At present, there is a flanged 90-degree elbow, that is, flanges are welded at both ends of the 90-degree elbow, and the end of the delivery pipe is also welded with a flange. The 90-degree elbow and the delivery pipe are connected by a flange, so that There is no need to weld when installing the delivery pipe, it can be connected by flanges and bolts. At the same time, it is also convenient to remove the delivery pipe or 90-degree elbow during pipeline maintenance, which is convenient for installation and maintenance. During processing, manual welding is mainly used between the flange and the 90-degree elbow in the flanged 90...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of low production efficiency and difficulty in ensuring the processing quality of the existing flange-type 90-degree elbow when welding flanges, the present invention provides a semi-automatic equipment for butt welding of 90-degree elbows and flanges. The 90-degree elbow The flange butt welding semi-automatic equipment adopts flange automatic alignment conveying device and elbow rotary fixture to respectively clamp the flange and the elbow to make the flange and the elbow correspond to each other. The flange and the elbow can rotate synchronously. The welding torch realizes the butt welding between the flange and the elbow, and the flange automatic alignment conveying device can keep the position of the bolt holes on each flange consistent, which has the characteristics of high production efficiency and good welding quality
