Abstract
An actuator assembly for a redraw sleeve that operates independently of the ram drive mechanism is provided. The actuator assembly utilizes a servomotor. The servomotor is structured to provide its output shaft with a variable rotation speed so as to accommodate the need for the redraw sleeve to be in selected locations at specific times.
Claims20
An actuator assembly for a redraw assembly, said actuator assembly comprising:
- a servomotor including a rotating output shaft;
- and
- wherein said servomotor produces a selectable rotational speed in said servomotor output shaft.
A redraw assembly comprising:
- a movable redraw sleeve;
- a redraw die;
- said movable redraw sleeve structured to move between a first position, wherein said movable redraw sleeve is spaced from said redraw die, and a second position, wherein said movable redraw sleeve is disposed immediately adjacent said redraw die;
- an actuator assembly for a redraw assembly including a servomotor;
- said servomotor including a rotating output shaft;
- said servomotor coupled to said redraw sleeve;
- and
- wherein said servomotor produces a selectable rotational speed in said servomotor output shaft.
5 more elements
The redraw assembly of claim 14 wherein:
- said servomotor has a maximum rotational speed of about 540 rpm;
- and
- said servomotor has a minimum rotational speed of about 125 rpm.
