Description

Technical Field

[0001] The utility model relates to the field of round pipe welding, in particular to a round pipe butt semi-automatic welding tooling device. Background Art

[0002] The product business undertaken by our company is mainly the casing crystallizer project. The main structure of the project is a round tube. However, during the production process, the company adopted the traditional manual conversion method for the casing crystallizer tube-to-tube connection welding process based on the process provided by Party A and the characteristics of the project operation scope. After the welding, there were many problems with the quality of the weld and the appearance of the weld. At the same time, it caused adverse effects on customers and reduced the brand reputation of the group. For this reason, the group's quality, safety and environmental protection department notified our company of the quality problem. In order to improve this problem and restore our company's quality reputation, we decided to tackle the problem of the weld quality of the casing crystallizer.

[0003] Through the summary of the production process and the analysis of the welding method, the main influencing factors of unqualified welds of the casing crystallizer are: weld bead, slag inclusion, spatter, incomplete fusion, too high joint, depression and porosity, etc. Statistical analysis shows that the main reasons for the low first-time qualified rate of the casing crystallizer welding are weld bead and slag inclusion.

[0034] The rotating wheel 6 and the wheel 9 arranged on the side can form the basic bearing structure for bearing the steel pipe. The substantial technical effect and its realization process, i.e. the basic function, of the technical solution here are as follows: by restoring the actual operation at the welding site, during the welding operation, since the welding angle changes continuously with the roundness of the round pipe, the operator's operating handle is unstable, the welding speed is uneven, and there are limitations on the welding position, which leads to too many weld defects. In order to avoid the occurrence of too many defects, the company's technical department and quality department, after discussion and analysis, decided to modify the process equipment to make the welding operation semi-automatic and reduce manual welding operations.

[0035] Therefore, the use of the rotating wheel 6 and the wheel 9 arranged on the side can constitute the basic bearing structure for bearing the steel pipe, can relatively position the steel pipe, and can effectively avoid manual movement of the steel pipe. By assisting in rotating the rotating wheel 6 or the wheel 9 on the side during the welding process, the uniform rotation of the steel pipe can be achieved, which facilitates welding with a robot and ensures a uniform weld.

Further increase and improve the corresponding process equipment to improve the automation level of this type of product during the welding process. Improve the level of semi-automatic production during the welding process.

[0038] This tooling equipment is simple, low in production cost, and easy to operate. Its role in reducing labor costs and improving product quality is far greater than its production cost, so there is no negative impact. Through the transformation of process tooling, the target value is achieved and the effect is obvious. The product quality is highly recognized by customers, further broadening the market for such products.
