ABSTRACT:
A rivet tool has a rivet pin which can be moved in a bore of a stamp die. The tool consists of a hydraulic cylinder having two pistons in which the first piston carries the rivet pin and the second piston carries the stamp die. The chamber between the pistons is connected with a variable volume pressure chamber. The cylinder chamber, which is facing the first piston, is connected with a pressure cylinder. After a rivet has been conveyed to beneath the rivet pin, a pressure cylinder is activated and a throttle interconnected between the chamber between the pistons and the pressure chamber. The stamping process is carried out hereby and the first piston is then pressed in direction of the second piston, whereby the first piston then lies on top of the second piston to effect the stamping process.
