Abstract
A device for driving inserts into pieces of sheet metal includes a punch having a longitudinal axis of symmetry, a thrust surface and a through hole extending along its longitudinal axis which constitutes a supply duct for the inserts. The through hole extends through the thrust surface. A thrust rod applies a driving force to the inserts to move them into position in front of the thrust surface of the punch. The thrust surface drives the head of the insert into a piece of sheet metal through a hole while plastically deforming the periphery of the hole which interfaces with the head.
