Shaping tool
The invention relates to a shaping tool which is used to shape a workpiece, in particular, a sheet steel component, comprising at least two shaping tool halves. Contoured regions are provided in the region of the shaping tool halves in order to give the workpiece a corresponding contour, at least in sections. Each shaping tool half has a shaping surface shell which is oriented towards the workpiece and a support shaping half. The shaping surface shell is arranged on the support shaping half and comprises a shaping surface, which is oriented towards the workpiece, and a rear side which is oriented away from the workpiece. The support shaping half comprises a contoured area which essentially corresponds to the contour of the workpiece which is to be produced and the contoured area is surrounded by a flange area. Grooves are provided in the contoured area in the region of the rear side of the shaping surface shell. The support shaping half comprises receiving surfaces which receive the support shaping half in a positive fit and the receiving surfaces and the grooves form cooling channels. The support shaping half comprises supply channels and discharge channels such that a coolant can be guided through the channels.
1. A shaping tool for shaping sheet steel components, the shaping tool comprising:
at least two shaping tool halves;
contoured regions are provided in a vicinity of the shaping tool halves in order to give a corresponding contour to at least one region of a work piece;
each shaping tool half has a shaping surface shell, which is oriented toward the work piece, and a form supporting half;
the shaping surface shell is arranged on the form supporting half and the shaping surface shell has a shaping surface oriented toward the work piece and a rear side oriented away from the work piece;
the form supporting half has a contoured region, which essentially corresponds to the contour of a work piece, and the contoured region is surrounded by a flange region;
grooves are provided in the contoured region in a vicinity of the rear side of the shaping surface shell;
the form supporting halves have receiving surfaces with a contour that corresponds to a rear side contour of the shaping surface shells, with the receiving surfaces and grooves forming cooling conduits; and
the form supporting halves have inlet conduits and outlet conduits connected to an inlet chamber and an outlet chamber, respectively, so that a coolant can be conveyed uniformly through the conduits.
