Claim Text:
1. An actuator assembly for a redraw assembly comprising: a servomotor including a rotating output shaft an eccentric journal assembly, said eccentric journal assembly coupled to said servomotor output shaft; a connecting rod assembly including a connecting rod, said connecting rod coupled to said eccentric journal assembly; wherein rotation of said servomotor output shaft causes said eccentric journal assembly to rotate between at least a first, rearward position and a second, forward position; wherein said connecting rod moves between a first, rearward position and a second, forward position corresponding to said eccentric journal assembly first and second positions; wherein said connecting rod is structured to be coupled to a movable redraw sleeve; said eccentric journal assembly includes a shaft and an eccentric journal; said eccentric journal assembly shaft having an axis of rotation; said eccentric journal being substantially circular; wherein eccentric journal is coupled to said eccentric journal assembly shaft with the center of said eccentric journal spaced from said eccentric journal assembly shaft axis of rotation; said connecting rod has a first end and a second end; said connecting rod first end includes a bearing assembly, said connecting rod first end bearing assembly structured to engage said eccentric journal; said connecting rod second end structured to be coupled to a movable redraw sleeve; said connecting rod second end includes a rotational coupling; said connecting rod assembly includes an oscillating shaft assembly; said oscillating shaft assembly including a pivot shaft, a drive arm, a pivot arm assembly, and a base; said pivot shaft rotatably coupled to said base; said drive arm including a first, proximal end and a second, distal end, said drive arm second, distal end having a rotational coupling; said drive arm first end coupled to said pivot shaft; said drive arm second end rotational coupling is rotatably coupled to said connecting rod second end rotational coupling; said pivot arm assembly including at least a first elongated pivot arm, said first pivot arm having a first end and a second end; said first pivot arm first end fixed to said pivot shaft; said first pivot arm second end including a rotational coupling; and said first pivot arm second end rotational coupling structured to be coupled to a movable redraw sleeve.
