Abstract

The invention proposes a lateral extrusion tool used for stirring friction butt welding of a plate. The tool comprises a threaded bottom plate, a welding compaction structure, fasteners and a backboard. The tool has the technical key points that the welding compaction structure is arranged on the upper sides of an extrusion block and a welded plate; a lateral compaction structure and the welding compaction structure are used for compacting the threaded bottom plate through the fasteners; and each of the lateral compaction structure and the welding compaction structure is provided with a long strip hole matched with the corresponding fastener. The tool is simple in structure, easy to mount and wide in applicability, and can adapt to effective clamping and limiting of relatively wide and thick welded plates, enable a butting surface to be always in a close-fit state and ensure that a high-quality stirring friction butt weld joint with stable performance is formed. Due to the addition of lateral extrusion force, the demand on surface compaction force of the welded plate can be relieved, and through the combined use of the backboard, the pressing marks of the welded plate can be reduced and even completely prevented.

Description

technical field [0001] The invention relates to the field of machinery industry, in particular to a lateral extrusion tooling for friction stir butt welding of plates. Background technique [0002] Friction stir welding is a high-quality solid phase joining technology, which has been widely used in the welding of various low melting point light metals since its invention. Friction stir welding mainly includes three technologies: stirring head structure design, effective process parameter planning and tooling structure design. The rationality of the tooling design directly determines the welding quality, production efficiency and labor intensity of the product, so the structural design of the friction stir welding tooling is a key technology that restricts the further development of this technology. [0003] At present, in the planar one-dimensional friction stir welding, the pressing method of the pressing plate is mainly used to squeeze and limit the plate to be welded. T...
