ABSTRACT:
A press for drawing associated raw material is disclosed that includes a die apparatus that has a top portion and a bottom portion, the associated raw material being drawn between the top portion and the bottom portion. The press also includes a stamping apparatus located above the die apparatus for stamping the associated raw material into the die apparatus. The stamping apparatus is movable up and down and exerts a downward force on the associated raw material and the die apparatus. The press also includes a coarse adjusting apparatus for making coarse adjustments to the press and a fine adjusting apparatus for making fine adjustments to position of the top portion of the die apparatus relative to the bottom portion of the die apparatus. The fine adjusting apparatus includes a rectangular binder ring plate located between the stamping apparatus and the top portion of the die apparatus, a plurality of cylinders pressurized with nitrogen and disposed within the binder ring plate, and a plurality of pistons disposed within the cylinder. The pistons are attached to the top portion of the die apparatus. The cylinders and pistons are grouped into control sets and controlled by a controlling apparatus. The press may be produced with the binder ring plate, or a binder ring plate may be retrofitted to an existing press.
