Abstract
The structure,main design parameters and work process of the compound die installed on single action press and working for blanking and drawing with constant blank holder pressure were presented.Thin rubber was used in the blank holder mechanism.The blank holder pressure was not affected by the course of drawing and kept constant for the whole process.The blank holder structure had good effect and applicability.
