Automatic welding treatment integrated machine for flange plates of pipeline installing and connecting joints

Abstract

The invention relates to an automatic welding and processing integrated machine for pipe installation and connection joint flanges, which includes a supporting base plate, a fixing device, a grinding device, a welding device, a rotating device and a post-welding processing device. The fixing device is installed in the middle of the supporting base plate Above, the grinding device is located above the fixing device, the grinding device is installed on the supporting base plate, the rotating device is located outside the fixing device, the rotating device is connected with the supporting base plate, the welding device and the post-welding processing device are installed on the rotating device, the welding device Located on the front side of the post-weld treatment unit. The present invention can solve the existing problems that the flange cannot be fixed multiple times when the flange and the steel pipe are welded, the flange is not firmly fixed, the flange needs to be manually polished before welding, and the flange is not polished before welding. Good, the welding action cannot be performed automatically, the post-weld treatment of the flange and the steel pipe is required manually, and the manual post-weld treatment is not thorough, etc.

Description

technical field [0001] The invention relates to the technical field of pipeline installation, in particular to an automatic welding and processing integrated machine for connecting joint flanges of pipelines. Background technique [0002] Flange connection is to fix two pipes, pipe fittings or equipment on a flange respectively first, then add flange pads between the two flanges, and finally tighten the two flanges with bolts to make them A detachable joint that is tightly combined. The flange is connected to the steel pipe by welding. The steps of flange welding are as follows. First, fix the flange, and then grind the chamfer of the flange before welding. The welding area of ​​the flange is polished smooth, which is beneficial to increase the welding effect. Then place the steel pipe on the flange and fix it. Manually use electric welding equipment to weld the interface between the flange and the steel pipe. The welding must be uniform For welding, the movement of the rot...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above-mentioned problems, the present invention provides an automatic welding processing machine for flanges of pipe installation and connection joints, which can solve the problems that existing flanges and steel pipes cannot be fixed multiple times and flanges are fixed. Weakness, manual grinding of the flange before welding, poor grinding effect of the flange before welding, inability to perform automatic welding action, manual post-welding treatment of the flange and steel pipe, incomplete manual post-welding treatment, etc. ; It can realize the functions of multiple stable fixing of the flange, pre-welding grinding of the flange chamfer, automatic welding of the flange and the steel pipe, and post-welding treatment of the welding spot between the flange and the steel pipe. The flange can be fixed multiple times, the flange is firmly fixed, the flange is automatically polished before welding, the flange is polished before welding, the welding action can be performed automatically, the flange and the steel pipe are automatically processed after welding, and the flange and the steel pipe are automatically processed. The advantages of clean and thorough post-welding treatment
