[0002] Screw riveting is a common mechanical joining process widely used to connect metal sheets, pipes, and other materials. It is particularly suitable for applications requiring high strength without the need for welding. During the riveting process, a combination of rotational force and axial pressure creates a secure connection between the rivet or stud and the workpiece surface. The riveting process typically does not require the addition of any additional materials (such as welding wire or glue), making it highly efficient, clean, and environmentally friendly.

[0003] The automatic riveting machine uses a punching machine and a special connecting die to form a stress-free internal inlaid dot with a certain tensile and shear strength through an instantaneous high-pressure processing process based on the cold extrusion deformation of the plate material itself.
