Abstract
A formation tool is used for deforming sheet metal on punching machines. The formation tool has an upper or top die tool and a lower or bottom die tool. Toward the top die, there is an upper mold insert movable relative to a holding-down device, and toward the bottom die, a lower mold insert movable relative to a stripper plate. The deformation of the metal sheet is effected upward with respect to a punching stroke plane. The formation tool has a lifting device for aiding in lifting the lower mold insert from an initial position which is at or below the punch stroke plane before a deforming operation, to a level above the punching stroke plane.
Claims9
A formation tool for sheet metal deformation on a punching machine, said die tool comprising:
- an upper top die tool;
- a lower bottom die tool;
- a holding-down device;
- a stripper plate;
- an upper mold insert being movable relative to the holding-down device, and cooperating with a lower mold insert, movable toward the bottom die relative to the stripper plate, to deform a metal sheet upward relative to a punching stroke plane;
