#CMT# #/CMT# The tool comprises a lower part (1) on which a sheet metal blank is placed, an upper part (2) that is adjustable in the direction of the lower tool part, and a handling tool for introducing the sheet metal blank into a free space between the tool upper part and the tool lower part. The handling tool comprises beam-like supporting members (5) on which the sheet metal blank is deposited, and is an electronically controlled robot. The lower part comprises a supporting contour (3) with recesses (6) in which the supporting members are inserted. #CMT# : #/CMT# The tool comprises a lower part (1) on which a sheet metal blank is placed, an upper part (2) that is adjustable in the direction of the lower tool part, and a handling tool for introducing the sheet metal blank into a free space between the tool upper part and the tool lower part. The handling tool comprises beam-like supporting members (5) on which the sheet metal blank is deposited, and is an electronically controlled robot. The lower part comprises a supporting contour (3) with recesses (6) in which the supporting members are inserted so that bearing surfaces of the supporting members are part of the lower tool part. A coolant and/or heating medium flows through one of the supporting members so that partial areas of the heat-molded metal blank rest on the curable supporting members. The supporting members are: embedded in the lower part so that the bearing surfaces lie in a plane formed by the supporting contour of the lower part; and insertable in the recesses of the lower part such that the bearing surfaces lie behind the plane formed by the supporting contour of the lower part or such that the bearing surfaces protrude against the plane. The supporting members comprise cooling channels that are connected to a coolant generator and/or a feeder. An electric or electronic control is provided to control coolant control valves of the coolant generator. The metal blank is made of a hardenable steel alloy. #CMT#USE : #/CMT# The tool is useful for heat molding and curing a sheet metal blank for fabricating a workpiece. #CMT#ADVANTAGE : #/CMT# The tool is capable of simply heat molding and curing the sheet metal blank with high efficiency thus providing the workpiece with high strength and high ductility. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic cross-sectional side view of a tool for heat molding and curing a sheet metal blank. 1 : Tool lower part 2 : Tool upper part 3 : Supporting contour 5 : Supporting members 6 : Recesses.
