Description

Technical Field

[0001] The utility model relates to the technical field of butt-joint welding equipment, in particular to a butt-joint clamping bracket. Background Art

[0002] The manufacturing process of welded steel pipes in the prior art usually involves bending and curling a steel plate into a cylindrical shape and then welding the two edges of the steel plate to obtain a steel pipe. The steel plate bending or curling process usually uses a bending machine to repeatedly press and bend the steel plate to bend the steel plate into a tubular shape. First, a bending machine is used to bend one half of the steel plate to form a C-shaped structure, and then the other half of the steel plate is bent by the bending machine to form another C-shaped structure. The two C-shaped structures are arranged opposite to each other to form a cylindrical workpiece with an opening. After the cylindrical workpiece is removed from the bending machine, the opening is manually spot welded and butt welded to form a complete steel pipe.

[0003] At present, the welding of cylindrical workpieces includes spot welding and butt welding processes. In order to ensure the forming quality of the cylindrical workpiece, spot welding must be performed before butt welding. After the cylindrical workpiece with an opening is butted to reduce the gap spacing, spot welding is performed manually at intervals to preliminarily form the cylindrical workpiece. In this way, the welding quality of the cylindrical workpiece can be improved in the later butt welding.

[0004] However, traditional spot welding operations are mostly performed manually through auxiliary tooling. Due to the frame structure design and its own characteristics of the auxiliary tooling, its own adaptive adjustment range is small and it is not suitable for welding cylindrical workpieces with a large diameter variation range. The operation is complicated and cumbersome, resulting in great difficulty and high labor intensity during manual welding. Moreover, the welding quality between the gaps of the cylindrical workpiece after spot welding is relatively low, which also affects the subsequent butt welding operation. Utility Model Content
