Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of friction welding, and relates to a friction welding machine capable of removing burrs. BACKGROUND

[0002] The friction welding machine is a method for welding by using the heat generated by the mutual friction of the end faces of workpieces to make them reach a plastic state and then completing the welding by top forging.

[0003] At present, in the process of friction welding of workpieces, the welding is performed by rotating one half of the un-welded workpiece at high speed and then pushing the other half of the un-welded workpiece to make them frictionally welded. However, a large amount of burrs will gradually be generated between the two workpieces during the friction process of pressing, which leads to the need for subsequent removal of the burrs on the surface of the welded workpiece by means of a cutter or polishing after the workpiece is stopped after welding. When hollow tubular workpieces are friction welded, not only the burrs on the outer surface of the pipe need to be removed, but also the burrs on the inner surface of the pipe need to be removed.
