Its advanced technology and automation functions make it one of the indispensable key equipment in modern manufacturing industry.

[0003] In high-speed precision punching machines, a clutch brake device is usually provided. The clutch brake device can control the transmission system of the precision punching machine so that the transmission device can be quickly connected or separated when needed, thereby realizing precise control of the movement of the punching machine. In high-speed precision punching machines, the friction disc in the clutch brake device plays a key role. The friction disc is responsible for transmitting power and torque in the clutch state, and transmitting power from the active disc to the driven disc to realize the movement of the punching machine.

However, the friction plate connected by bolts may loosen due to vibration and workload during use, and may introduce unnecessary gaps between the friction plate and the friction disc, affecting the friction performance and transmission efficiency, especially under high-speed operation or high load. It may have an adverse effect.
