Definitions

the invention relates to a method for producing molding tools, in particular drawing tools.
Forming tools of this type are usually made from blanks, on which extensive cutting work such as milling, planing, etc. is used for shaping. must be carried out. This leads to high processing costs.
the object of the invention is therefore to simplify the production of such molds.
the object is achieved in that the tool shape is formed from a sheet metal to which the actual tool body is cast.
the tool shape is obtained by hammering or other known working methods.
the sheet itself is made of either steel or titanium. Its surface, which is relevant for sheet metal processing, is hardened by a diffusion process, for example by carburizing or riveting, and is thus given a wear-resistant surface which allows the tool to have a long service life. This surface treatment of the sheet metal is expediently carried out before the actual tool body is cast on, but subsequent treatment is also conceivable.
the tool body has essentially only a carrier function and therefore does not need to be made of a high quality material.
Low-melting alloys based on aluminum or zinc are particularly suitable for this. These materials have the advantage that they can be easily reused when the mold is no longer needed.
the drawing shows in the single figure one half of a drawing tool 1, which is composed of a sheet 2 forming the tool shape and the actual tool body 3.
the tool body 3 consists of a zinc alloy and is cast onto the sheet 2.
Anchoring elements 4 ensure a firm connection between the sheet metal 2 and the tool body 3.
the anchoring elements 4 are welded to the sheet metal 2 with one end, while the other projects into the tool body 3.
the sheet 2 is made of steel. Its side 5 facing away from the tool body 3 and decisive for sheet metal processing is hardened by carburizing or nitriding.
