Description

Technical Field

[0001] The utility model relates to a forming and welding tooling for large arc plates, belonging to the technical field of forming and welding of large arc plates. Background Art

[0002] Large cylinders have large dimensions and weights. The assembled large cylinders are too large to be transported and need to be disassembled into several parts and then transported to the installation site for welding. For some manufacturers where welding is not allowed due to environmental requirements, large cylinders that are easy to disassemble and assemble need to be designed. The large cylinder is composed of several arc plates that are detachably connected. It is necessary to weld connecting parts at the edges of the arc plates. Welding is a complex process, and it is necessary to select a suitable welding method, strictly control the welding process, and ensure that the welding quality meets the requirements. Only in this way can the structural strength and sealing performance of the large cylinder be guaranteed to meet the needs of industrial production. The quality requirements for the welding of the arc plate and the connecting part are very strict, including aspects such as the surface quality of the weld, the weld size, and the internal quality of the weld. The surface of the weld should be flat and smooth, and no external defects are allowed.

[0003] When welding the connecting plates of the large cylinder that can be disassembled and assembled, after the worker welds the unilateral connecting plate to the arc plate, then welds the other sides. This is time-consuming and laborious, and the welding quality cannot be guaranteed. It is crucial to develop a forming and welding tooling for large arc plates during the welding process.
