TOOLING ADJUSTMENT

摘要

A method for use in a press having cooperating punch and die members aligned for reciprocatory movement along a common axis of each to form thin walled hollow cup-shaped containers upon said punch members drawing material through said die members with the following steps: supplying a portion of said material in a plane between said punch and die members when same are apart and there is a space therebetween prior to drawing; moving said punch members along said axis toward said die members for drawing said material through said die members; adjusting the radial spacing between said punch and die members by controlling the operating temperature of either in accordance with variations in said material.
