Description

Technical Field

[0001] The present application relates to the technical field of workpiece processing, and in particular to a riveting tool. Background Art

[0002] Riveting is a method of connecting workpieces in mechanical processing. Riveting can provide high-strength connections, such as connecting parts through rivets or rivet studs. This connection method is usually stronger than welding or bolting.

[0003] However, riveting generally uses a stamping machine to cold extrude and deform the workpiece material to form an inlay point with a certain tensile and shear strength. The pressure required for riveting is relatively large, but long-axis workpieces are prone to bending, and when processing the ends, long-axis jitter may occur, thereby reducing processing accuracy and easily affecting the quality of riveting.
