Japanese Patent JPH084860
Kind Code:
B2
Abstract:
A method of forming a container in one or more double acting presses includes the steps of blanking, drawing an inverted cup and reverse drawing the inverted cup while retaining a flange thereon at a first station and then transferring the cup to a second station where the cup is drawn to an inverted configuration and then reverse drawn to form a finished container again retaining the flange throughout. The drawing operations at each station are performed in a single stroke of the press. The apparatus at the first station includes a blank and draw punch and a fixed, hollow die core ring with the punch telescoping over the ring to form the inverted cup and a draw horn telescoping within the ring to reverse draw the cup. The apparatus at the second station includes a hollow redraw sleeve and a pressure sleeve telescoping over the redraw sleeve to invert the cup and a profile punch telescoping within the redraw sleeve to reverse draw the cup.
