Description

Technical Field

[0001] The utility model relates to the technical field of stir friction welding processing, in particular to a stirring needle and a shaft shoulder chip removing device of stir friction welding equipment. Background Art

[0002] Friction stir welding refers to the use of the heat generated by the friction between the high-speed rotating welding tool and the workpiece to partially melt the material to be welded. When the welding tool moves forward along the welding interface, the plasticized material flows from the front to the back of the welding tool under the action of the rotating friction force of the welding tool, and forms a dense solid phase weld under the extrusion of the welding tool.

[0003] The shoulder is one of the core components of the static shoulder process to generate friction heat. After the high-speed rotating stirring needle and the workpiece generate friction heat to locally plasticize the welded material, a dense weld is formed under the forging pressure of the shoulder.

[0004] In the actual working process of static shoulder stir friction welding, the stirring needle and the shoulder will contact the workpiece to be welded. After working for a long time, waste chips will be deposited on their surface. If they are not cleaned, it will easily lead to defective parts in the future. Therefore, in view of the above situation, we need to provide a chip removal device for the stirring needle and the shoulder to overcome the above defects. Utility Model Content
