ABSTRACT:
An apparatus for automatically fixing the self-piercing nuts has a striking punch (2) for causing the end face of each nut (N) to pierce a metallic panel (P) laid on a caulking die (1) and to be fixed to the panel, and also has a mechanism for intermittently feeding the nuts. The mechanism is composed of a rigid frame (6) to which a slide guide (3) is fixed and a movable chute (8) having a distal opening (8a) communicating with a feeding aperture (5) opened in the slide guide and a proximal opening (8b) communicating with a flexible chute (7). The movable chute (8) held in and connected to the rigid frame (6) is driven by an actuator (22) mounted on the frame so as to swing between an operative and inoperative positions. The distal opening (8a) of the movable chute (8) is partially closed with a side face of the striking punch (2) or of the slide guide (3) every time when the movable chute swings to its inoperative position, so that the apparatus as a whole is made lighter, smaller and easier to remote control.
