Abstract
Example methods and devices for producing a shaped component may involve positioning a workpiece having a hollow region and consisting at least partially of steel in a mold of a device. One or more docking punches may secure the workpiece within the mold and serve to introduce a pressurized fluid into the hollow region of the workpiece within the mold. The workpiece may be hot-formed in this process. The present disclosure concerns a variety of methods and devices that may be utilized to counteract a cooling of the workpiece in a region of the docking punch and reduce a temperature difference that may exist between the workpiece and the device.

A method for producing a shaped component:
- positioning a workpiece having a hollow region and consisting at least partially of steel in a mold of a device;
- using a docking punch to introduce a fluid under pressure into the hollow region of the workpiece positioned in the mold;
- hot-forming the workpiece in the mold;
- and
- counteracting a cooling of the workpiece in a region of the docking punch.
A device for performing the method of claim 1, the device comprising:
- a mold for receiving the workpiece;
- a docking punch for introducing a fluid into the hollow region of the workpiece;
- and
- a mechanism for counteracting a cooling of the workpiece, the mechanism disposed in a region of the docking punch.
A device for shaping a workpiece having a hollow region and comprising a steel material, the device comprising:
- a mold for receiving the workpiece;
- a docking punch for introducing a fluid into the hollow region of the workpiece;
- and
- a mechanism for counteracting cooling of the workpiece, the mechanism disposed in a region of the docking punch.
