Abstract
A sheet metal tool as two relatively movable tool sections, one of which is rovided adjacent its sheet metal-shaping face with a sheet metal holder which is movable relative to that face. Also movable relative to that face is a pressure-distributing unit composed of two spaced parallel plates which are maintained at a predetermined distance by spacers, this unit serving as an abutment for the sheet metal holder.
Claims4
Tool for shaping--particularly drawing--of sheet metal, comprising a movable upper tool section mounting a die and a field lower tool section mounting a punch mounted for movement towards and away from one another;
- a sheet metal holder provided on one of said sections and movable relative to a sheet metal-shaping contour thereof;
- and pressure distributing means also movable relative to said shaping contour and including two spaced-apart plates and spacers connecting said plates and maintaining them at a predetermined distance, said pressure distributing means constituting an abutment for said holder;
- said spacers comprising tubular spacing sleeves arranged between said plates;
- said sleeves each comprising a cylinder of a fluid-operated cylinder and piston unit, and a piston slidable back and forth in said cylinder;
- said piston being supported at one side of said pressure distributing means by a piston rod extending through one of said spaced-apart plates.
