5.5.4 PUNCH BRAKE ASSEMBLY OPERATION - Figure 5-8
The Punch Brake Assembly consists of a Brake Hub (1) attached to the end of the Punch
Motor Shaft (3, Figure 5-5), and the Lever Arm (2) attached to a Solenoid (3). The
Solenoid (3) is wired in parallel with the Punch Motor (1, Figure 5-3), and energizes
when the punch cycle starts. The Lever Arm (2) retracts, allowing the Brake Hub (1) and
Punch Motor (1, Figure 5-5) to rotate. When the Punch Motor (1, Figure 5-5) and
Solenoid (3) de-energize, the Lever Arm (2) engages the Brake Hub (1), stopping
(braking) the Punch Motor Shaft (3, Figure 5-5) rotation.
The Punch Motor Brake Assembly is used to ensure the Punch Pins (2, Figure 5-6) are
stopped in the home position after each punch cycle.
