Tonnage Control for a Drawing Operation in a Double-Action Press 1999-01-0686

Drawing is the most important operation in stamping. Shut height has been used as the main control parameter in die setup. But shut height control can not provide a consistent binder force for a drawing operation in a double-action press and often produces formability and/or quality problems. This paper will examine how different input variables will affect the performance of a drawing operation in a double-action press. Three examples of using tonnage control and process optimization are provided in improving part quality and reducing down time and scrap cost.
