[0002] The hot die forging press is a modern forging equipment for precision metal forming, which has the advantages of high precision, high productivity and automation compatibility. In order to improve safety, a pneumatic friction clutch is usually provided when the hot die forging press is used. The working principle of the pneumatic friction clutch-brake system in the hot die forging press is as follows: under normal conditions, the spring force separates the clutch friction disc, and the brake friction disc is pressed tightly; when working, the air pressure presses the clutch friction disc tightly, and the brake is separated, which ensures fast response and safe braking.
