Can body maker with magnetic ram bearing and redraw actuator |
摘要 |
A can body maker apparatus of the type having an axially reciprocal ram member and an axially reciprocal redraw carriage comprising a ram position sensing assembly for sensing the position of the ram member and for generating a ram position signal in response thereto; an electromagnetic bearing assembly for frictionlessly radially supporting and aligning one end of the ram member with a predetermined ram displacement path; an electromagnetic redraw carriage actuator for applying magnetic force to the redraw carriage for reciprocating the redraw carriage; and a control assembly for selectively energizing and deenergizing electromagnets in the electromagnetic bearing assembly and the electromagnetic redraw assembly in response to the ram position signal.
