Tool beneficial for large circular pipe welding and welding deformation control and implementation method of tool

Abstract

The invention provides a tool beneficial for large circular pipe welding and welding deformation control and an implementation method of the tool. The problem that in the prior art, due to the fact that the one-time percent of pass of circular pipes is low after the butt joint connection is conducted and multiple times of correction need to be conducted generally, adverse effects on the production quality and the construction period are caused is solved. The tool comprises a working table, a first sleeve, a second sleeve and a duplex central frame, wherein the first sleeve and the second sleeve are installed on the two sides of the working table respectively, the duplex central frame is arranged in the middle of the working table, the first sleeve, the second sleeve and the duplex central frame share the same center line, bearings are arranged in the first sleeve and the duplex central frame respectively, a circular pipe fixing device is arranged in the second sleeve, a motor is linked with the circular pipe fixing device through a transmission device, and the duplex central frame is of a structure with an opening in the middle. By means of the tool beneficial for large circular pipe welding and welding deformation control, the welding efficiency and quality of the circular pipe butt joint connection can be improved, the control over the welding deformation is achieved after welding is conducted, and the straightness of the circular pipes which are connected in a butt joint mode is ensured.

Description

technical field [0001] The invention relates to the field of steel structure manufacturing, in particular to a tooling for large-scale round pipe welding and welding deformation control and a method for realizing the same. Background technique [0002] Nowadays, round pipes are used more and more in steel structure buildings, especially large-scale lattice columns are more and more widely used in various buildings because of high material utilization, good structural stability, and beautiful appearance. . However, with the development of the construction industry, the requirements for the length and straightness of the round pipe in a certain component are getting higher and higher, and it is impossible to greatly increase the length when the raw materials leave the factory. The butt joint is carried out to obtain the required length, which puts forward higher requirements for the butt joint quality of the round pipe. First, there must be a good welding process to ensure th...
