良鋲抜取装置。 A punched-out pin in the form of a tapered pin, the outer diameter of the end of which comes into contact with the regular-shaped rivet head is slightly smaller than the outer diameter of the rivet shaft after the rivet has been tacked, and the outer diameter gradually increases as it moves away from the end. a second snap having a recess for accommodating a malformed rivet head at the end opposite to the small diameter end of the first snap; , is removably attached to one end of the riveting machine frame, which is approximately U-shaped, and the other snap is removably attached to the end of the piston shaft of a hydraulic cylinder mounted on the other end of the frame; An ejector made of an elastic material such as rubber that presses the annular remaining material of the punched rivet head toward the small diameter end of the pin is provided on the outside of the punching pin of the first snap. At the end of the pin removal small diameter end,
A device for extracting defective rivets, characterized in that a protective cap is installed to prevent excessive deformation of the ejector in the radial direction.
