摘要： 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 (60) to be produced. A device for producing dimensionally highly accurate sheet-metal components is moreover described.

摘要： A method for producing a formed component is disclosed. The method includes: preforming a workpiece to a preformed component having a base region, a wall region, and optionally a flange region, wherein a material quantity adaptation is set in the preformed component; and calibrating the preformed component to a finally formed component, at least in regions, having a base region, a wall region, and optionally a flange region, wherein compressing of the preformed component is performed at least in regions during the calibrating. The method provides a formed component wherein the dimensional accuracy is improved and, in particular, any spreading of the walls of U-shaped components or part-portions can be influenced in a targeted manner, so as to further improve the dimensional accuracy of the formed component. The material quantity adaptation is set by way of a base-specific material quantity adaptation, a wall-specific material quantity adaptation, a radii-specific material quantity adaptation, and/or optionally a flange-specific material quantity adaptation. A formed component made by the method is also disclosed.

摘要： The present invention concerns a method for production of a supporting member with an at least partially closed cross-section, having at least a first metal shell and a second metal shell which are connected together at least in portions in the longitudinal direction. The method includes a provision of at least a first and a second metal blank. At least a first and a second metal shell are produced from the respective first and second metal blanks. The first and second metal shells each have at least one floor with two protruding uprights spaced apart from each other and integrally connected to the floor. The first and second metal shells are positioned such that the uprights of the metal shells come into overlapping contact.

摘要： A method for producing sheet metal components is disclosed. The method includes preshaping a workpiece to form a preshaped component. Excess material is introduced into the preshaped component at least in regions. The method includes, calibrating the preshaped component to form an at least partially finally shaped component using the excess material. The preshaped component is compressed at least in sections. The method achieves high dimensional accuracy, rigidity and/or hardening of components. According to one aspect of the method, different regions of the preshaped component are calibrated in a time-staggered manner, or one or more locally thickened region are produced during the calibration.

摘要： A method for producing a formed, flanged component is disclosed. The method includes the steps of: preforming a workpiece a preformed component; and calibrating the preformed component to a substantially completely formed component. The method strengthens the reinforcement in the component and widens the spectrum of application to components in particular, to tub-shaped components. The calibrating of the preformed component to the completely formed component includes stretching the preformed component at least in portions. The present disclosure relates further to a device for producing a formed, flanged component.

摘要： 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.
