ACTUATOR WITH VARIABLE SPEED SERVO MOTOR FOR REDRAW ASSEMBLY
摘要:
An actuator (50) for a redraw sleeve (40) that operates independently of the ram drive mechanism (14) is provided. The actuator (50) utilizes an eccentric journal (62) coupled to a drive shaft (58) of a servomotor (52). The servomotor (52) is structured to provide its output shaft (58) with a variable rotation speed so as to accommodate the need for the redraw sleeve (40) to be in selected locations at specific times. Further, the redraw sleeve (40) includes a collapsing redraw cylinder (144) to allow the redraw sleeve (40) to dwell in a forward position.
