Rivet setter

摘要

A rivet setter which can efficiently and smoothly perform the rivet setting operation even when setting rivets each having a shank of its length smaller than a diameter of its head. The rivet setter can be configured to set a rivet sequentially fed one by one from a rivet supplying means by inserting the rivet into apertures formed at predetermined positions on workpieces. The rivet setter can comprise delivery paths for delivering the rivet one by one by forcing the rivet to be slid down to a settable position. The rivet setter can include notches formed on the bottom surfaces of the delivery paths along the rivet delivery direction and extending to the settable position for supporting the head of the rivet in the course of delivery of the rivet on the delivery paths and for hanging the shank of the rivet downward.

1. A rivet setter for setting rivets sequentially fed one by one from a rivet supplying means by inserting the rivets into apertures formed at predetermined positions on workpieces, the rivet setter comprising:
delivery paths for delivering the rivets one by one by forcing a rivet to be slid down to a settable position; notches formed on bottom surfaces of the delivery paths along a rivet delivery direction and extending to the settable position for supporting a head of the rivet in the course of delivery on the delivery paths and for hanging a shank of the rivet downward; and a stopper configured to projected and retract relative to the delivery paths for stopping the rivet at a waiting position by interfering with the rivet in the course of deliver on the delivery paths to the settable position; wherein each of the notches has a notch width greater than a diameter of the shank of the rivet and less than a diameter of the head of the rivet; and wherein each of the notches extends from the settable position at least to the waiting position.
