Method and device for forming a corner limited on three sides, from a plate-shaped material with an even surface |
摘要 |
The invention relates to a method and a device for forming a corner bounded on three sides from a flat plate part, in particular sheet metal, whereby the side edges adjacent to the corner are folded back across a major part of their longitudinal extension parallel with the flat plate part and shaped on a curved path in the region in which the corner is to be formed from the folded-back side edge to the plane of the flat plate part. The pre-formed blank is then pressed at the curved transition region by means of at least one roller system (42), spanning the corner region (10) between the side edges, against a tool (16) and the corner shaped by forming the material and optionally trimmed in a cutting device.
