System for forming an elongated container

Abstract

A system for forming a cup used in forming an elongated container including a draw-redraw station including a movable platen carrying a punch shell; a punch core riser, a punch core mounted on the punch core riser; and a first, fluidly actuated pressure sleeve; and a fixed base carrying a pressure pad; a die core ring; and a die core; the punch shell being movable toward the die core ring to wipe the blank over the die core ring to form an inverted cup; the punch core being movable toward the die core to reverse draw the inverted cup and form the cup; and the die core ring engaging the material against the punch core during the reverse draw to control metal thickness; and a cooling assembly including a chiller, a coolant passage formed in the punch core and fluidly connected to the chiller.
