Setting device for conical spring washers

摘要

The device consists of a driven impact piston (6), and a relatively movable retainer ring (7) for the washer. Piston and ring are guided in a common housing (4). The housing has a holder (5) for connection of a compressed air gun. The impact piston is retained in the rest position by a pressure spring (15). The retainer ring has a central aperture for the piston, and is held on the piston via a spring (13), which presses it against a circumferential shoulder (9). The ring has permanent magnets (12) to hold the washers.
