Method and device for producing a shaped component

摘要

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.

1. 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, wherein the counteracting comprises reducing heat transfer from the workpiece to the device in the region of the docking punch by reducing thermal conductivity of the device in the region of the docking punch by utilizing a material with a thermal conductivity of less than 40 W/(m*K) in the region of the docking punch.
