Definitions

  • the invention relates to a method for producing a metal component according to the preamble of claim and its use and a batch furnace with the features of the preamble of claim 11.
  • a board is heated differently in a continuous furnace, so that arise due to the different material temperatures after forming various strengths in the metal component.
  • the board is tempered differently in the passage in two furnace chambers, so that set different structural areas in the curing process.
  • This method has the disadvantage that only two to three different zones with respect to the strength and elongation at break in the metal component can be achieved. These can also be formed only in the direction of passage of the board beyond.
  • the passage direction of a steel part or a circuit board usually corresponds to the greatest longitudinal extent of the steel part or the circuit board.

  • the method is characterized in that the forming tool for hot forming comprises means for tempering, with which a steel part in different temperature zones can be tempered during the forming to different, predetermined temperature values.
  • the forming tool for hot forming comprises means for tempering, with which a steel part in different temperature zones can be tempered during the forming to different, predetermined temperature values.
  • the present invention is therefore based on the technical object of providing a method and a device for producing a metal component, which permits a local adjustment of the microstructure in the metal component and at the same time is cost-effective and easy to carry out.
  • this object is achieved in that the cooling rates different from one another are brought about by sections of the tool surface which correspond to the subregions of the steel part and which differ from one another in their heat conductivities.
  • the cooling of the steel part in the forming tool is strongly influenced by the thermal conductivity of the forming die surface. Under the thermal conductivity is understood in particular the heat transfer coefficient.
  • the presence of different microstructures is effected in the steel part or in the metal component produced. If the cooling rate in a partial region of the metal component is more than 27 K / s, a predominantly martensitic microstructure results there with a high strength and a low elongation at break. At a lower cooling rate, a ferritic-bainitic structure with an average strength and a mean elongation at break, a ferritic-pearlitic structure with a low strength and a high elongation at break, or a mixture thereof. Ferritic-bainitic and ferritic-pearlitic structures have a tensile strength below 860 MPa.

  • the thermal conductivity of the tool surface can be influenced in a simple way. In particular, adjacent sections with greatly different thermal conductivities can be produced in this way.
  • the number of sections is generally not limited to two, but can be any size.
  • at least three sections are provided, so that set in the metal component three sub-areas with different types of structures or strengths, at least a portion of a predominantly martensitic microstructure and have at least two further subregions predominantly ferritic-bainitic and / or ferritic-pearlitic structure.
  • a particularly favorable thermal conductivity and at the same time sufficient stability for use in a tool is achieved in a further exemplary embodiment in that the sections consist of steels, steel alloys and / or ceramics.
  • At least one of the two sections of the tool surface has a heat conductivity reducing or increasing surface coating.
  • the heat conduction of the tool surface is modified by the surface coating.
  • the above object can be achieved in a method for producing a metal component, in particular a motor vehicle component, in which a steel part is heated, wherein the heated steel part is at least partially cured by cooling in a tool, wherein the steel part after hardening at least two partial areas with having different microstructure, be achieved in that the steel part is tempered before curing in a batch oven having at least two areas, wherein the areas have different temperatures from each other.
  • a batch furnace is understood to mean a furnace in which the steel part to be heated is essentially not moved during the heating process.
  • the batch furnace thus stands in contrast to the continuous furnace, in which the steel part is moved continuously through the furnace during heating.
  • a method according to the first embodiment is additionally performed.
  • the effect on the microstructure of the metal component can be enhanced so that, for example, very different microstructures in adjacent subregions of the metal component can be produced.
  • the arrangement of the regions of the batch furnace preferably corresponds to the arrangement of the sections of the tool surface. However, deviating arrangements are also conceivable.

  • a homogeneous heating preferably to a temperature in the range or above the Austenitmaschinestemperatur or the Ac 3 temperature can be performed.
  • the partial areas of the steel part can then be heated or cooled to the target temperatures for the subsequent hardening process.
  • the cooling is preferably carried out in such a way that premature hardening of the steel component does not yet occur.
  • the second furnace may in particular be designed as a continuous furnace. In this way, a fast and continuous provision of the metal components for the batch furnace is made possible.
  • the steel part is hardened in a pressing tool.
  • the hardening of the steel part is preferably carried out immediately after the temperature control in the batch furnace in order to avoid an equalization of the different tempered portions by the heat conduction of the steel part.
  • a continuous course of the material properties in the metal component is achieved in a preferred embodiment of the method according to the invention in that the batch furnace has at least one region with a temperature gradient.
  • the steel part is cooled in at least a portion of the batch furnace by controllable gas nozzles, in particular with nitrogen.
  • the areas are realized in the simplest way with mutually different temperatures in the batch furnace.
  • the number of heating elements can be reduced.
  • a flexible adjustment of the temperatures in the batch furnace is possible by the controllability of the gas nozzles. So can be set by the controls different areas for various metal components.
  • the controllable gas nozzles can be used as an alternative to controllable heating elements or in combinations with these. Nitrogen is the preferred cooling gas because it is cheap and inert.
  • the steel part is directly or indirectly hot-worked and / or press-hardened.
  • the steel part is formed in at least two steps, preferably first by cold working and then by hot working.
  • direct hot forming however, the forming takes place in a single hot-forming step. Indirect hot forming can be advantageous, especially at high draw depths.
  • a particularly flexible design of the metal component is achieved in a further embodiment in that at least one boundary between the subregions extends transversely or obliquely to the greatest longitudinal extent of the steel part and / or non-linearly.
  • the method thus allows a substantially arbitrary adjustment of the subregion boundaries to each other.
  • the boundaries between the subregions are furthermore preferably arranged outside joining regions of the steel part, in order to avoid impairment of joining connections, in particular welding seams, by the transition region in the region of a boundary.
  • a semifinished product in particular a tailored blank, a tailored-welded blank, a patchwork blank or a tailored-rolled blank, or a cut-to-size blank is used as the steel part.

  • the steel part may have an inorganic coating, preferably an aluminum or aluminum-silicon-based coating, in particular a fire-aluminized coating (fal), and / or a zinc-based coating.
  • a functionalization of the surface of the metal component is possible, so that the material properties can be adapted even more flexible.
  • the technical problem is solved according to a second teaching of the present invention by using a Metal component, prepared according to one of the methods described above, in a motor vehicle, in particular as A-, B- or C-pillar, side wall, roof frame or side members solved. Due to the flexible and locally adjustable material properties of the metal components they can be optimally adapted to the loads in a motor vehicle, in particular to improve the crash behavior.
  • the difference in thermal conductivity can be achieved in a preferred embodiment of the tool in that the sections consist of different materials, in particular steels, steel alloys and / or ceramics, with different thermal conductivities.
  • the tool surface coming into contact with the steel part is at least partially arranged on various exchangeable segments and / or tool inserts of the tool. In this way it is possible to flexibly rearrange or rearrange the exchangeable segments or tool inserts in the tool, so that with a tool metal components with different structural arrangements and consequently with different properties can be produced.
  • a simple realization of the different thermal conductivities is achieved in a further embodiment of the tool in that at least one of the sections has a heat conductivity reducing or increasing surface coating.
  • very local changes in the thermal conductivity can be achieved in this way.

  • the technical problem is further solved in a batch furnace for heating a steel part for a hot forming process and / or press hardening process, in particular for carrying out one of the previously described processes, according to the invention, in that the batch furnace has at least two regions in which different temperatures can be set.
  • a steel part can be tempered to different temperatures, so that different types of microstructures are achieved in the metal component produced in a subsequent hardening process.
  • At least one region of the batch furnace has controllable gas nozzles for cooling.
  • Fig. 1 shows a tool for producing a metal component of the prior art in longitudinal section.
  • the tool 2 is designed as a hot forming tool and has a lower punch 4, an upper punch 6 and two Flanschgir 8 and 10.
  • the mutually facing surfaces 12 and 14 of the lower and upper punch 4, 6 have a profile which corresponds to the outer contour of the metal component to be produced from a steel part 16.
  • Temperianss institute 18 are further provided, with which the temperature in the region of the surface 14 of the upper punch 6 can be adjusted.
  • Comparable Temper réellesetti can also be provided in the lower punch 4. The distances between the adjacent tempering elements 18 differ from each other, so that the surface 14 has a location-dependent temperature profile.
  • the steel part 16 designed as a board is arranged between the spread apart punch 4 and 6 and the punch 6 is lowered onto the punch 4. In this way, the board is hot-formed at the same time and experiences a cooling with location-dependent cooling rates. This leads to a corresponding location-dependent structural change in the steel part.
  • the flange portions 20 of the Steel part 16 can be trimmed by lowering the flange blades 8 and 10. Due to the uneven arrangement of the Temper réelles institute 18, the tool 2 has a complicated structure, which in particular requires the use of a large number of tempering.
  • Fig. 2 now shows a first embodiment of a tool or method in longitudinal section.
  • the tool 30 differs from that in FIG Fig. 1 illustrated tool 2 in that the lower punch 4 has different sections 32, 34, 36, 38, which consist of different materials with different bathleitrangeen.
  • the materials used are preferably steels, steel alloys and / or ceramics.
  • the upper punch 6 may consist of several sections made of different materials. The sections can also consist only in the area of the surfaces 12 and 14 of different materials. Due to the different thermal conductivity of the individual sections 32, 34, 36, 38, hot cooling or hardening of a steel part 16 leads to different cooling rates and thus to the formation of different microstructures within the steel part 16.

  • an alternative lower punch for a tool for example, the in Fig. 2 shown tool shown.
  • the lower punch 50 in Fig. 3a consists of a plurality of separate segments 52a to 52p, which can consist of different materials with different thermal conductivities.
  • the entire surface 54 of the punch 50 thus has a location-dependent thermal conductivity, so that different cooling rates in the steel part can be effected with a tool containing this punch 50 in a hot forming or hardening process.
  • Some or all of the segments 52a to 52p may be essentially arbitrarily exchanged or swapped. So are in the in Fig.
  • 3b illustrated lower punch 56 of an embodiment of a tool according to the invention, the segments 52f and 52j replaced by other segments 52q and 52r of a different material. Furthermore, the segments 52d and 52e and the segments 52g and 52h are reversed in position. Depending on the number of segments and the materials available, the sections of the surface 54 of the lower dies 50, 56, which differ in their thermal conductivities, can thus be adapted flexibly in a simple manner. Alternatively, of course, the upper punch or both stamps may consist of separate segments.
  • Fig. 4 shows a further embodiment of a tool according to the invention or a method according to the invention in longitudinal section.
  • the surface 14 of the lower punch 4 has sections 66, 68, 70 and 72, of which the sections 66, 70 and 72 are coated with surface coatings 74, 76 and 78.
