Title:
CLUTCH MECHANISM AND BRAKE MECHANISM IN POWER PRESS AND ITS DRIVE METHOD
Document Type and Number:
Japanese Patent JPS5868499
Kind Code:
A
Abstract:
A clutch and brake system for starting and stopping a power press uses hydraulically actuated brake and clutch mechanisms. To start the press, the brake is hydraulically released (t11) while the clutch is hydraulically engaged (t11) at a predetermined intermediate torque level which is less than the full clutch torque level. The clutch is maintained at that intermediate torque level until the present drive shaft has attained its substantially full speed, and is then (t12) increased to the full clutch torque level. To stop the press, the clutch is hydraulically disengaged (t14) while the brake is hydraulically engaged (t14) at a predetermined intermediate torque level which is less than the full brake torque level. The brake is maintained at this intermediate torque level until the press drive shaft has substantially stopped, at which time (t15) the brake torque is increased to the full brake torque level.
