Benefits of technology

The present invention is a hot forming tool which is easy to retrofit and can be quickly changed between production batches. It includes a carrier tool and a mold segment that can be easily connected and disconnected without the need for additional bolts. The tool also includes quick-action clamping and coupling systems that allow for the attachment of various passages and connections, such as cooling liquid, without the need for additional steps. This design reduces the time and cost of maintenance and change-over between production batches.

Problems solved by technology

As the press hardening tool is normally made of tool steel, the incorporation of cooling ducts in the press hardening tool becomes complex.

Abstract

A hot forming tool for the production of a press hardened sheet steel product includes an upper tool and a lower tool. At least one of the upper and lower tools has a base plate, a carrier tool mounted on the base plate, and a mold segment exchangeably received in the carrier tool and configured specific to the sheet steel product.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims the priority of German Patent Application, Serial No. 10 2014 107 210.3, filed May 22, 2014, pursuant to 35 U.S.C. 119(a)-(d), the disclosure of which is incorporated herein by reference in its entirety as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]The present invention relates to a hot forming tool for the production of a press hardened sheet steel product, to a hot forming line, and to a method for operating a hot forming line.[0003]The following discussion of related art is provided to assist the reader in understanding the advantages of the invention, and is not to be construed as an admission that this related art is prior art to this invention.[0004]It is generally known in the art to shape metal products of hardenable steel alloys in their hot state and then to cool them down rapidly enough to effect quenching and ultimately hardening. Blanks are typically heated in a tempering station or fu...
