Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a welding deformation prevention tooling. Background Technique

[0002] In modern manufacturing, welding is a widely used connection process. However, the high temperature generated during welding will cause uneven distribution of thermal stress inside the workpiece, resulting in the problem that the workpiece is prone to deformation. Welding deformation may cause the product not to meet the design requirements, increase the scrap rate, and raise the production cost.

[0003] In the special tooling for limiting the welding deformation of the product disclosed in the publication number CN219767231U, although the workpiece is fixed by the upper and lower support members, the installation reinforcement frame rotates the long bolt to make it tightly connected with the fulcrum of the upper support member to ensure the stability of the workpiece without falling off. The workpiece is rotated, and with the assistance of the upper and lower rotating shaft wheels, the workpiece can be rotated and welded.

[0004] However, the special tooling for limiting the welding deformation of this product has the following disadvantages: only relying on the downward pressure of the bolt to provide the fixing and supporting strength for the pipe fitting, the stress point is small, and there is a risk of deformation at the welding position due to the downward inclination of both ends when the pipe fitting is long, and it is difficult to effectively control the welding deformation fundamentally.
