Title:
METHOD FOR OPERATING A COMBINED CLUTCH- AND BRAKE DEVICE OF A PUNCH PRESS
Document Type and Number:
WIPO Patent Application WO/2020/010476
Kind Code:
A8
Abstract:
The invention relates to a method for operating a combined clutch- and brake device (5) of a punch press (1), equipped with dry friction linings (7, 8). The friction linings (7, 8) are located in a chamber (R) which is sealed off from the environment of the punch press (1) and which is filled with a dry, oil-free gaseous medium, in particular dry, oil-free air. This effectively prevents moisture and oil mist from entering the region of the friction linings from the area surrounding the press, and allows a constant friction coefficient to be maintained over the mechanical service life of the friction linings.
