Devices and Methods for Pressure Forming Connecting Webs Between Workpiece Parts of a Plate-Like Workpiece

摘要

A forming tool for pressure forming a connecting web between incompletely separated workpiece parts of a plate-like workpiece from a cutting operation, in particular a metal sheet, comprises two tool parts, of which each is provided with a forming unit. The tool parts are able to move towards each other along a stroke axis with a processing stroke to a stroke end position. Each of the forming units has a forming surface on a web side facing away from the respective workpiece part, wherein the said forming surface, starting from a front face of the forming unit extends along the stroke axis away from a workpiece side facing the respective workpiece part.

主权项

1. A forming tool for pressure forming a connecting web attached by ends of the connecting web to workpiece parts to connect the workpiece parts together, the forming tool comprising
a first tool part having a first forming unit and positioned on a first side of the connecting web; and a second tool part having a second forming unit and positioned on a second side of the connecting web opposite the first side, wherein the first tool part and the second tool part are configured to move relative to one another along a stroke axis that extends transversely to the first side and the second side of the connecting web, wherein the first forming unit has a first face and the second forming unit has a second face facing toward the first face; wherein each of the forming units has a workpiece side and a connecting web side, wherein the workpiece side of each of the forming units is configured to face the same workpiece part when pressure forming the connecting web, wherein the connecting web side of each of the forming units is configured to face away from the same workpiece part when pressure forming the connecting web, wherein the first tool part and the second tool part are configured to move relative to each other along the stroke axis with a processing stroke to a stroke end position in which there is a gap between first face and the second face along the stroke axis, wherein, when pressure forming the connecting web, the gap is smaller than a height of the connecting web along the stroke axis, and wherein each of the forming units has a forming surface on the connecting web side that extends along the stroke axis from the face of the respective forming unit away from the workpiece side of the respective forming unit.
