The present invention relates to a method for producing a dimensionally stable sheet metal component, wherein the method includes preforming a metal sheet into a sheet metal preform comprising at least one base region, a frame region, a transitional region between the base region and the frame region, optionally a flange region and a transitional region between the frame region and the flange region, wherein at least one of the regions comprises excess material at least in portions. The sheet metal preform is cut at least in portions to form a cut sheet metal preform with a sheet metal preform The sheet metal preform is one of swagged and calibrated which has been cut at least in portions to form a substantially finished formed sheet metal component.

Method for producing sheet metal components and device therefor

A method for producing dimensionally highly accurate sheet-metal components is provided. A blank is formed to a preformed part, wherein the preformed part in the cross section at least in regions has an excess developed length. The preformed part is calibrated in regions to a calibrated part while at least in regions using the excess developed length of the cross section of the preformed part, wherein the preformed edges of the preformed part during the calibrating are at least in regions disposed so as to be free of any form-fit. The calibrated part is trimmed at least in regions after the calibrating, in order for the sheet-metal component () to be produced. A device for producing dimensionally highly accurate sheet-metal components is moreover described.

Method and device for producing sheet-metal components

A method for producing a wheel disk of a vehicle wheel may involve producing the wheel disk produced from a steel blank by hot forming. The blank may be at least partially hardened, preferably press-hardened, during or after the hot forming. The blank may be hot formed using at least one punch and at least one die, and at least one opening may be introduced into the blank using hot trimming means. At least one opening may be introduced during the hot trimming using at least one trimming bolt and an application bolt, wherein the application bolt may have at least one region having a cross-sectional shape that is variable in a longitudinal direction of the application bolt. Using the application bolt, the at least one opening may be calibrated via the variable cross sectional shape.

Process and device for producing hot-formed wheel naves

The invention relates to a method for bending at least one edge of a composite sheet, which has at least two outer metallic layers and an inner plastic layer, in which the edge of the composite sheet is edge-bent in a first step and is bent into the finished form in at least one further method step. In addition, the invention relates to a correspondingly bent composite sheet. The object of making a method for bending a composite sheet available, in which cracks in the metallic layers of the composite sheet can be prevented and, at the same time, in which a seam can easily be provided, is achieved by using an edge-bending punch, a holding-down device and an edge-bending jaw during the edge-bending operation and by the edge-bending punch having a notch running in the bending direction below the bending edge of the edge-bending punch.
