- the base body may initially be formed of a material that is easy to machine, in particular, by machining, preferably a light metal alloy.
- a wear protection board is then provided, which is formed from a relation to the material of the body more solid material, in particular a tool steel.

- the parting line may be formed in the form of a gap, in the parting line, for example, an insulating material may be arranged or the parting line may also be formed approximately gap-free, but in particular between the individual segments, a heat conduction greatly reduced or avoided.
- This makes it possible to temper the two segments of the base body different from each other, so that different strength properties can be adjusted by the cooling of the component in a sharply bordered transition area.
- transition regions of less than 100 mm, preferably less than 80 mm, in particular less than 50 mm and most preferably less than 30 mm are set in the component.

- machining methods such as a drilling or milling method can be used, which can be dispensed with a complex channel system.
- the cooling channels from one side of the base body are designed to pass through the same to the other side as a through-bore, since sufficient heat dissipation is achieved on account of the high heat conduction properties of the main body or of the respective segment.

- the creation of the cooling channels is particularly cost possible, which in turn turn out the total tooling costs significantly lower than in a made of conventional tool steel hot forming tool.
- Cooling media used are, in particular, fluid media, that is to say cooling fluids which, in the simplest embodiment variant, can also be formed from water, since the use of light metal alloys results in a lower susceptibility to corrosion compared with steel materials. Furthermore, however, air or compressed air or other gaseous media can be used as the cooling medium. Furthermore, it is possible within the scope of the invention to set the cooling rate required individually for the area of the component by size, thus cross-sectional area of the cooling channel and / or pressure of the cooling medium and / or the flow velocity of the cooling medium through a respective segment. In particular, the adjustment of a tensile strength is alloy-dependent in regions between 1,500 and 2,000 MPa and, in contrast, regionally between 750 and 1,050 MPa possible. Thus, it is possible according to the invention in the two adjacent segments each of the upper tool and / or the lower tool from each other to set different cooling rates and thus strength properties in the component.
- the wear protection plates themselves are in turn preferably formed from a high-strength or ultra-high-strength steel material.
- the wear protection boards are arranged in particular on the base body of the thermoforming tool that they are easily interchangeable after a certain production time, so that the dimensional stability of the components produced therewith is given, but not the entire upper tool or lower tool or the entire thermoforming tool replaced or completely must be revised.
- the wear protection boards are particularly preferably interchangeable or releasably coupled to the main body or the segments of the base body.
- a Verschier conspiracyplatine thus bonded to the body and / or positively coupled, in particular by a rivet or screw.
- a thermal compound between the wear plate and body is arranged so that an intense heat transfer occurs by conduction and the hot-formed component can be purposefully quenched.
- the wear protection boards are also segmented.
- a parting line is formed between the individual wear protection board segments, the may have a gap, or is formed approximately gap-free, with an insulating material in the parting line can be used.

- This variant is to be understood both peripherally at least in sections circumferentially, but also, for example, completely circumferential edge.
- a hold-down device is arranged on the deep-drawing tool on at least two opposite sides.
- the hold-down device can either be formed on both sides, so that it is completely arranged next to the upper tool or the lower tool and is preferably movable separately to both upper tool and lower tool.
- the hold-down can also be designed such that it is formed only on one side, for example, coming from the lower tool or coming from the upper tool and then coming umzuformende board clamped on the upper tool or on the lower tool to the plant.
- the hold-down is preferably formed separately movable both to the upper tool and the lower tool.
- FIGS. 1a and b show an inventive thermoforming tool 1 in the case of FIG. 1a in a cross-sectional view and FIG. 1b in a longitudinal section view.

Between the individual segments 9a, 9b, 9c, 10a, 10b, 10c are parting lines 11, here in the form of a gap. In the joints 11 itself can also be arranged an insulating material. This avoids that a heat conduction below the segments 9a, 9b, 9c, 10a, 10b, 10c takes place. Furthermore, it can be seen that in this embodiment, the cooling channel 8 only through the respective middle segment 9b, 10b run.
- the central segment 9b, 10b can be cooled both in the upper tool and in the lower tool 3, so that a corresponding homogeneous heat dissipation of an upper tool 2 and a lower tool 3 takes place only in the area of the component, which is not shown in detail.
- the areas adjacent thereto, which are located in the segments 9a, 9c, 10a, 10c, are not detected by the cooling in this case.

- FIGS. 7a and b show a further alternative embodiment in which not the segments of the body are directly and actively cooled, but in each case a bottom plate 21 is connected, wherein in the bottom plate 21, a plurality of cooling channels 8 is formed.
- the heat is thus removed via the wear protection plates 6, 7 through the base body 4, 5 and the bottom plate 21. Due to the high thermal conductivity of the base body 4, 5, it is again possible to realize a corresponding heat dissipation.
