Moulding Tool for Producing Hot-Formed Components

Abstract

A molding tool is provided for producing hot-formed components, in particular moulded sheet metal parts consisting of steel, aluminium, magnesium or a combination thereof. The tool has a lower tool part and an upper tool part which are displaceable relative to one another and have corresponding active areas for forming the component. At least some sections of at least the active area of one tool part can be cooled and the molding tool is provided with at least one descaling device.

What is claimed is: 
     
         1 . A molding tool for producing a hot-formed component, comprising:
 a tool lower part and a tool upper part which are movable relative to one another and which are configured with corresponding active faces for shaping the component, wherein   at least an active face of one of the tool parts is configured so as to be cooled at least in sections; and   at least one descaling device for the molding tool.   
     
     
         2 . The molding tool according to  claim 1 , wherein the component is a shaped sheet metal part made from steel, aluminum, magnesium or a combination thereof 
     
     
         3 . The molding tool according to  claim 1 , wherein the descaling device is configured as an extraction and ejection device. 
     
     
         4 . The molding tool according to  claim 1 , wherein the descaling device is configured as an air curtain. 
     
     
         5 . The molding tool according to  claim 3 , wherein the descaling device is also configured as an air curtain. 
     
     
         6 . The molding tool according to  claim 1 , wherein the descaling device is arranged in front of the molding tool in an introduction direction of the component. 
     
     
         7 . The molding tool according to  claim 3 , wherein the descaling device is arranged in front of the molding tool in an introduction direction of the component. 
     
     
         8 . The molding tool according to  claim 1 , wherein the molding tool comprises a plurality of descaling devices which are arranged around the active face of the tool. 
     
     
         9 . The molding tool according to  claim 1 , wherein the descaling device is arranged on the tool upper part, on the tool lower part or on both tool parts. 
     
     
         10 . The molding tool according to  claim 1 , wherein the descaling device is operatable intermittently, said descaling device being switched off at least in a completely closed state of the molding tool and being switched on in a completely open state of the molding tool. 
     
     
         11 . The molding tool according to  claim 10 , wherein the descaling device is switched on after every forming operation or after a predefined number of forming operations. 
     
     
         12 . The molding tool according to  claim 11 , wherein the descaling device is activated in a manner which is dependent on a state of the molding tool. 
     
     
         13 . The molding tool according to  claim 1 , wherein air channels are provided in at least one tool part, via which air channels air is appliable to the active face of the tool part.
