Embodiment Construction

[0034] figure 1 The lower mold 1 of the thermoforming mold 2 according to the present invention is shown. The lower mold 1 has a base plate 3 for this purpose, on which a supporting mold 4 assembled side by side is arranged. On the supporting mold 4 on the left side with respect to the plane of the view, a molding section 5 is again nested or at least partially accommodated. For this reason, it can be clearly seen that the supporting mold 4 on the right side of the view is configured with a receiving cavity 6 having a rectangular structure. To this end, the molding section 5 itself is divided into a bottom plate in the form of a support receiving portion 5a and a real molding die 5b protruding from the support receiving portion 5a. On the upper mold not shown further, a complementary molding mold is provided on the actual molding mold 5b, preferably also on the replaceable molding section. A cooling channel interface 8 is constructed in the bottom 7 of the accommodating cavit...

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

Technical field [0001] The invention relates to a hot forming die for manufacturing press-formed steel plate products according to the features described in the preamble of claim 1. [0002] The invention also relates to a thermoforming line according to the features described in the preamble of claim 15. [0003] The invention also relates to a method of a thermoforming line according to the features of claim 17. Background technique [0004] Hot press forming and pressure quenching techniques are known from the prior art. A metal product made of a hardenable steel alloy is processed in a hot state and then rapidly cooled as follows so that it is quenched and hardened at the same time. [0005] In the initial state, slabs are mostly provided, which then reach a temperature above the austenite temperature in a tempering station or furnace. Then the slab heated in this way is placed in a forming mold and processed into a shape with at least partial heating. Here, a relatively high d...
