  • Patent number: 4562717
    Abstract: A drawing punch for use in drawing foils in a die which converges in the direction of drawing. The punch has a rigid core, a cylindrical elastic body on the core and surrounding the core with a cavity therein around the core and opening out of the end of the body facing the direction of drawing. A rigid support member is provided on the core against which the other end of the body is supported. The radial cross-sectional area of the cylindrical elastic body increases from the firstmentioned end of the body toward the other end, and the peripheral surface of the cylindrical elastic body is at a positive angle to the axis of the punch of from 0.degree. to 20.degree.. The cavity has a volume which becomes zero just before the end of the stroke of the punch into the die.
