Abstract

The invention relates to a method for producing a component, said method comprising: preforming a workpiece to a preformed component having a base region, a side-plate region, and optionally a flange region, such that the preformed component has a material surplus for the side-plate region and/or the base region and/or optionally the flange region; and calibrating the preformed component to an at least in regions finally formed component having a base region, a side-plate region, and optionally a flange region; wherein the base region of the preformed component has substantially the geometry and/or the local cross sections of the base region of the at least in regions finally formed component. The invention moreover relates to a device for producing a component, in particular for carrying out the method.

First claim

The invention claimed is:

1. A method for producing a component, said method comprising the following steps:
preforming a workpiece to a preformed component having a base region, a side-plate region, and a transition region such that the preformed component has a material surplus wherein the preforming is carried out in a preforming tool comprising a preforming die, a preforming swage, and a preforming swage base that is movable relative to the preforming swage, wherein the workpiece is disposed between the preforming die and the preforming swage base, and wherein the workpiece is preformed by a relative movement between (i) the preforming die and the preforming swage base, (ii) the preforming swage base and the preforming swage, and (iii) the preforming die and the preforming swage; and
calibrating the preformed component to the component having a base region, a side-plate region, and a transition region; wherein
the base region of the preformed component during calibration is impinged with a force on both sides thereof which enables compressing of the base region of the preformed component and avoids collapsing of the material surplus, wherein the base region of the preformed component has substantially at least one of a geometry and a local cross section of the base region of the component, wherein the material surplus is provided by the transition region between the base region and the side-plate region of the preformed component.

2. The method as claimed in claim 1 , wherein the shape of the transition region between the base region and the side-plate region of the preformed component leads to an elevated or lowered base region of the preformed component.

3. The method as claimed in claim 1 wherein the material surplus is provided substantially by the transition region between the base region and the side-plate region of the preformed component.

4. The method as claimed in claim 1 wherein the shape of the transition region between the base region and the side-plate region of the preformed component, when viewed in the cross section, provides an additional length for at least one of the base region and the side-plate region of the preformed component.

5. The method as claimed in claim 1 wherein the preforming is carried out by a deep drawing operation with or without blank holders.

6. The method as claimed in claim 1 wherein the calibrating is carried out by a calibrating tool comprising a calibrating die, a calibrating swage, and a calibrating swage base that is movable relative to the calibrating swage, wherein the preformed component is disposed between the calibrating die and the calibrating swage base, and wherein the preformed component is calibrated by a relative movement between (i) the calibrating die and the calibrating swage base, and (ii) the calibrating swage base and the calibrating swage.

7. The method as claimed in claim 6 , wherein the calibrating swage comprises calibrating swage side plates and wherein during the calibrating of the preformed component, the swage side plates converge toward each other.

8. A method for producing a component, said method comprising the following steps:
preforming a workpiece to a preformed component having a base region, a side-plate region, and a transition region such that the preformed component has a material surplus; and
calibrating the preformed component to the component having a base region, a side-plate region, and a transition region; wherein
the base region of the preformed component during calibration is impinged with a force on both sides thereof which enables compressing of the base region of the preformed component and avoids collapsing of the material surplus, wherein the base region of the preformed component has substantially at least one of a geometry and a local cross section of the base region of the component, wherein the material surplus is provided by the transition region between the base region and the side-plate region of the preformed component; and wherein the calibrating is carried out by a calibrating tool comprising a calibrating die, a calibrating swage, and a calibrating swage base that is movable relative to the calibrating swage, wherein the preformed component is disposed between the calibrating die and the calibrating swage base, and wherein the preformed component is calibrated by a relative movement between (i) the calibrating die and the calibrating swage base, and (ii) the calibrating swage base and the calibrating swage; wherein the calibrating swage comprises calibrating swage side plates and wherein during the calibrating of the preformed component, the swage side plates converge toward each other.
