Abstract

A forming tool includes at least one first die half where the first die half has an insert part which is designed to move a finished component out of the first die half along a direction of motion where a displacement direction of the insert part is inclined relative to the direction of motion.

First claim

What is claimed is:

1. A forming tool, comprising:
a first die half; and
an insert part, wherein at least a portion of an outer contour of a finished component is formable by the insert part and wherein the finished component is displaceable out of the first die half along a movement direction by the insert part;
wherein a displacement direction of the insert part is inclined in relation to the movement direction;
wherein the insert part comprises a portion of an ejector unit, wherein the ejector unit has two insert parts, and wherein respective displacement directions of the insert parts are oriented away from one another at least to an extent;
wherein each of the two insert parts has a lower portion that is disposed under the finished component both when the forming tool is closed and when the forming tool is open and wherein the respective lower portions are disposed adjacent to one another at a vertical center plane of a cavity defined by the forming tool and in which cavity the finished component is disposed.

2. The forming tool according to claim 1 further comprising a second die half which is closable along a closing direction to form a cavity in the forming tool;
wherein the displacement direction, at least to an extent, is inclined in relation to the closing direction and is oriented away from the cavity.

3. The forming tool according to claim 2 , wherein the second die half is an upper tool half of the forming tool and the first die half is a lower tool half of the forming tool and wherein the forming tool is a hydroforming tool.

4. The forming tool according to claim 2 , wherein the displacement direction is inclined at an angle ranging from 0.5° to 45° in relation to the closing direction and/or the movement direction.

5. The forming tool according to claim 1 further comprising a plurality of ejector units.

6. The forming tool according to claim 1 , wherein the insert part is mounted in the first die half via a prestressing element.

7. The forming tool according to claim 1 , wherein the insert part is configured such that the insert part is prestressed as the forming tool is being closed.

8. A method for producing a component, comprising the acts of:
producing the component in a forming tool, wherein the forming tool has a first die half with an insert part, wherein at least a portion of an outer contour of the produced component is formed by the insert part;
opening the forming tool and displacing the insert part along a displacement direction which is inclined in relation to a movement direction of the produced component; and
ejecting the produced component from the forming tool along the movement direction by the displacing of the insert part;
wherein the insert part comprises a portion of an ejector unit, wherein the ejector unit has two insert parts, and wherein respective displacement directions of the insert parts are oriented away from one another at least to an extent;
wherein each of the two insert parts has a lower portion that is disposed under the finished component both when the forming tool is closed and when the forming tool is open and wherein the respective lower portions are disposed adjacent to one another at a vertical center plane of a cavity defined by the forming tool and in which cavity the component is disposed.
