Embodiment Construction

[0042] Figures 1, 2 respectively show schematic cross-sectional views of the side plate area 2, 2' and the bottom area 4, 4' of a component 1, 1' for illustrating an embodiment of the method for a component 1, 1' Effect.

[0043] Component 1 in Figure 1 has a bottom-specific material adaptation in the form of a material addition or upset allowance of +2%, and a side plate-specific material adaptation in the form of a material addition or upset allowance of +3% . As a result of the upsetting indicated by arrow 6 during the alignment process, material flows from the side plate area into the bottom area, as indicated by arrow 8 . have been determined by simulation and in Figure 1b As shown in , this results in a reduction in the side plate opening angle or the distance between the ends of the side plates (arrows 10, 12). As a result, a CAD-accurate bottom radius can be achieved, and the outward springback of the side plate area 2 can be counteracted, thereby improving dimensi...

Abstract

The invention relates to a method for producing a shaped component, the method comprising: preforming a workpiece into a preformed component having a base region, a side panel region and optionally a flange region, wherein material is carried out in the preformed component Quantitative matching; and calibration of the preformed component as an at least regionally final formed component having a bottom region (4, 4', 44), a side panel region (2, 2', 42) and optionally a flange region (1,1', 40), wherein the preformed component is at least regionally upset during calibration. The object of the present invention is to provide a method in which the dimensional accuracy is further increased, in particular the expansion of the side panels of the U-shaped component or part section can be influenced in a targeted manner, so that the dimensional accuracy is further increased. This object is solved in this way, That is, material volume matching including base specific material volume matching, side panel specific material volume matching, radius specific material volume matching and / or flange specific material volume matching is performed optionally. The invention also relates to a profiled component (1, 1', 40).

Description

technical field [0001] The invention relates to a method for producing a shaped component, the method comprising: preforming a workpiece into a preformed component having a base region, a side panel region and optionally a flange region, wherein material is carried out in the preformed component and calibrate the preformed component as an at least regionally final formed component having a bottom region, a side panel region and optionally a flange region, wherein the preformed component is at least regionally upset during calibration . The invention also relates to profiled components. Background technique [0002] In the production of components, especially in the production of U-shaped open profile components by means of deep drawing, after the component is taken out of the tool, due to the inevitable elastic rebound, most of the bottom and sides of the component Elastic expansion occurs between the panels, or between the side panels and the optionally present flange. T...
