Abstract
A clamp device for securing a bending press punch on its punch holder, the clamp device being capable of securing punches having a straight, or flat, contacting surface and those having a groove on the contacting surface. The clamp device comprises a plurality of spring members each secured about a bolt; an upper punch clamp plate member having a punch contacting surface; and a lower flanged punch clamp plate member having a punch contacting surface. The spring members provide the force necessary to return the upper punch clamp plate member to a position wherein a portion thereof is within the groove when the grooved punch is used. When the flat surface punch is utilized, the punch contacting surface portion of the lower punch clamp plate member and the punch contacting surface of the upper punch clamp plate member are positioned against the contacting surface of the punch thus providing solid surface contact when either punch design is utilized.
