Definitions

  • the present invention relates to a method for producing a motor vehicle component with at least two areas with mutually different strengths and a protective layer according to the features in claim 1.
  • motor vehicle components by means of sheet metal forming.
  • sheet metal outer skin components are produced, for example an engine hood or a roof skin.
  • motor vehicle structural components are also produced. These are, in particular, motor vehicle pillars, roof pillars, rocker panels, cross members or longitudinal members, as well as other structural components built into the motor vehicle body.
  • the components made of a hardenable steel alloy are, however, at the same time susceptible to corrosion, which is why it is also known from the prior art to provide hot-formed and press-hardened components with a corrosion protection layer.
  • the object of the present invention is to provide a possibility to manufacture motor vehicle components inexpensively with corrosion protection, which specifically have sharply edged areas with mutually different strengths.
  • the method thus initially provides for the provision of precoated starting material made of a hardenable steel alloy.
  • This can be a steel material unwound from a coil, which has already been separated into blanks, or it can also be cut directly from blanks.
  • a blank has an approximately near-net-shape trim that the component should have after hot forming.
  • This raw material is pre-coated.
  • this is an aluminum silicon coating.
  • the hardenable steel alloy is preferably a boron-manganese steel.
  • the starting material is heated to a heating temperature that is greater than or equal to the AC3 temperature of the iron-carbon diagram of the hardenable steel alloy.
  • This warming-up temperature is also preferably maintained for a period of time, in particular for 90 s to 300 s.
  • the pre-coating is alloyed with the board. This is also called diffusion of the Called pre-coating in the surface of the board.
  • the coating preferably has a layer thickness between 20 ⁇ m and 40 ⁇ m. In particular, a pronounced intermetallic phase is formed.
  • the homogeneous heating to the warm-up temperature is carried out in particular in a continuous furnace.
  • the intermediate cooling temperature is between 450 ° C. and 700 ° C., but it is at least lower than the warming-up temperature and therefore particularly preferably lower than AC1.
  • the intermediate cooling temperature +/- 50 ° C. is also preferably kept for a holding time.
  • One or more material structures can be set in a targeted manner through the intermediate cooling and in particular due to the temperature range of the intermediate cooling. If the intermediate cooling temperature is selected at approx.
  • the material structure changes predominantly into bainite, which after quench hardening has a tensile strength of 750 MPa to 1050 MPa.
  • the intermediate cooling temperature is selected at approx. 600 ° C, a predominantly ferritic / pearlitic structure is formed, with a tensile strength of approx. 500 MPa to 750 MPa after quench hardening.
  • a bainitic material structure to an intermediate cooling temperature of approx. 500 ° C with a cooling rate between 3 to 15 ° C / sec. cooled down.
  • the subsequent holding time is preferably 30 s to 90 s.
  • the homogeneously intercooled and alloyed plate is partially from the intermediate cooling temperature +/- 50 ° C in areas first Type and therefore heated in areas to at least AC3 temperature.
  • the remaining areas are called areas of the second type, which are essentially kept at the intermediate cooling temperature +/- 50 °.
  • Warming the areas first Type to at least AC3 temperature, preferably to 930 ° C. to 980 ° C., is preferably carried out in such a way that the areas of the first type completely austenitize.
  • the blank which is partially tempered in areas with different temperatures, is transferred to a hot forming and press hardening tool, hot formed in this tempered state and then press hardened.
  • a tensile strength greater than 1400 MPa is thus set in the areas of the first type and a tensile strength Rm less than 1050 MPa in the areas of the second type.
  • a transition area between the areas of the first type and the second type has a width of less than 50 mm.
  • this can be achieved in that the partial heating of the areas of the first type to at least AC3 temperature is carried out in a particularly short time, in particular at a heating rate greater than 30 ° C./sec.
  • the time for heating is preferably less than 20 s, in particular less than 15 s, particularly preferably less than 10 s.
  • the heat conduction that occurs in the blank from areas of the first type to areas of the second type takes place only to a small extent due to the shortness of the time, so that a sharp-edged transition area with the subsequent hot forming and press hardening is achieved.
  • the cycle time for hot forming and press hardening is preferably approx. 10 s to 20 s, in particular 15 s. Furthermore, a relatively short transfer time between the completion of the intermediate cooling or the end of the holding time of the intermediate cooling and the hot forming and press hardening tool is realized.
  • the transfer time is preferably 2 s to 15 s.
  • the homogeneous heating to the warm-up temperature is particularly preferably carried out in a continuous furnace.
  • the homogeneous intermediate cooling to the intermediate cooling temperature as well as the optional maintenance of the intermediate cooling temperature is also carried out in a continuous furnace.
  • This continuous furnace for intermediate cooling is preferably designed as a continuous furnace module and, in particular, is connected directly to the continuous furnace for heating to the warm-up temperature.
  • the intermediate cooling can also be carried out in a chamber furnace.
  • structural components for motor vehicles in particular can thus be produced which are intended to have small-area, strip-like and / or island-like soft areas, and consequently areas of the second type.
  • These can be trigger strips or side wall islands, for example, so that targeted deformation points are first deformed in the event of a vehicle crash.
  • Coupling points, in particular coupling flanges of the components for coupling two motor vehicle components to one another with areas of the second type, thus soft areas, can be designed so that in the event of a motor vehicle crash and deformation, the coupling points are prevented from tearing off in these areas and the tendency to crack along later joints is reduced .
  • a width of the transition region smaller than 40 mm, in particular smaller than 30 mm and particularly preferably smaller than 25 mm. Areas with very sharp edges and different strengths can thus be delimited.
  • the areas of the second type are preferably designed to cover or occupy only a small area in relation to the total area of the motor vehicle component.
  • the predominant part of the motor vehicle component should therefore have a hardened material structure, thus areas of the first type. More than 70%, in particular more than 80% and particularly preferably more than 90% of the motor vehicle component preferably has areas of the first type.
  • the intermediate cooling to the intermediate cooling temperature can be carried out in several stages and thus at least in two stages.
  • a first stage of the intermediate cooling has a higher cooling rate compared to a second stage with a lower cooling rate. This means that the temperature decreases more strongly in the first stage of the intermediate cooling.
  • the temperature is less than one decreased for a longer period.
  • the at least two-stage intermediate cooling can then in turn be followed by a holding phase at the intermediate cooling temperature.
  • a predominantly bainitic structure or a predominantly ferritic / pearlitic structure is set.
  • a mixed structure of ferrite, pearlite and bainite can also be set during the intermediate cooling.
  • the partial heating is then carried out by, in particular, contact heating of the areas of the first type.
  • the areas of the second type are kept in particular at essentially the intermediate cooling temperature.
  • the partial heating takes place particularly preferably by contact heating.
  • contact plates are placed on the surface of the fully alloyed board. There is a conduction, i.e. heat conduction from the contact plate into the board.
  • the contact plate preferably has a temperature that is greater than or equal to the AC3 temperature.
  • the contact plate itself is heated by induction, by thermal radiation, in particular by torch heating.
  • a heating means for example a heating cartridge or heating wire, can also be assigned to the contact plate.
  • the contact plate itself is designed as an electrical resistance heater. By applying an electrical voltage to the contact plate, the contact plate heats up itself. If the contact plate is placed on the board, heat is conducted from the contact plate into the board, at least in the areas of the first type to be austenitized.
  • the partial heating can be carried out in an oven which has at least two zones. It is also possible to integrate cooling plates or temperature control plates in an oven or to place them on the board so that the cooling plates of the areas of the second type are kept at the intermediate cooling temperature and areas of the first type are heated to a temperature greater than or equal to AC3 in the oven.
  • the oven can be designed as a continuous oven, but also as a chamber oven, deck oven or buffer oven.
  • the areas of the first type can be heated directly by means of laser radiation. This is particularly useful if particularly large areas of the second type are provided, which consequently should not be heated to above AC3.
  • motor vehicle components are thus produced as structural components. These are preferably motor vehicle pillars, very particularly preferably A-pillars or B-pillars.
  • side members can also be produced.
  • bars in particular roof bars or rockers can be produced.
  • chassis components can also be produced with the method according to the invention.
  • coupling flanges, desired deformation points, coupling areas, hole edges, trigger strips and / or side wall islands are formed as areas of the second type and therefore softer areas.
  • a multi-drop tool as the hot forming and press hardening tool.
  • a double or quadruple dropping tool This means that two components are formed at the same time during one movement and, after the forming process has been completed, the two components are also press hardened at the same time.
  • four blanks are formed into components at the same time during a closing movement and all four components are then press-hardened.
  • two individual temperature control stations can be used for a double hot forming and press hardening tool.
  • Both a cooling station for intermediate cooling and a partial heating station for partial heating to via AC3 can be referred to as a temperature control station.
  • a temperature control station can be used for a double hot forming and Press hardening tool.
  • two individual intermediate cooling stations and / or two individual heating stations can be used for a double hot forming and Press hardening tool.
  • two double-falling tempering stations can be used, i.e. two double-falling cooling stations and two double-falling partial heating stations.
  • Figure 1 shows a hot forming line 1 according to the invention for carrying out the method according to the invention.
  • a blank 2 is provided in the form of a blank and here in particular for a B-pillar. This passes through a continuous furnace 3, the blank 2 being heated to a temperature greater than or equal to AC3 temperature in a first heating zone 4 of the continuous furnace 3.
  • the blank 2 has the heating temperature.
  • it can also have the warm-up temperature before reaching the end 5 and then maintains the warm-up temperature for the rest of the time of the warm-up zone 4.
  • the pre-coating alloyed through with the blank 2 so that at the end 5 of the heating zone 4 the coating was completely alloyed through with the blank 2.
  • an intermediate cooling zone 6 in which the blank 2 is cooled to a temperature between 450 ° C. and 700 ° C., but at least less than the heating temperature.
  • the homogeneously intermediate cooled blank 8 has the intermediate cooling temperature.
  • the homogeneously intercooled board 8 is then transferred to a contact heating station 9, whereby by closing the contact heating station 9, the board 2 is partially heated to a temperature in areas of the first type 10 of at least AC3 by area-wise contact with the contact plates 9a.
  • the board 2 In areas of the second type 11, the board 2 has a temperature which essentially corresponds to the intermediate cooling temperature +/- 50 ° C.
  • this is achieved in that the area of the first type 10 has direct system contact with contact plates 9 a of the contact heating station 9.
  • the regions of the second type 11 do not lie directly on the contact plates 9a, so a recess 9d is arranged between them as an insulating air gap 9b.
  • the contact plates 9a are themselves heated by a heating means 9c, for example an inductor.
  • the areas of the first type 10 and the areas of the second type 11 on the temperature-controlled blank 12 are to be equated with the areas of the first type 10 with high strength and the areas of the second type 11 with a comparatively lower strength after hot forming and press hardening.
  • the partially tempered blank 12 is then immediately transferred to a hot forming and press hardening tool 13 and formed by hot forming and press hardening to form the motor vehicle component 14 with two areas with mutually different strengths.
  • the production of a B-pillar is illustrated here, wherein the blank is adapted to the final contour of the B-pillar after the forming and the B-pillar has a hat-shaped profile in cross section after the forming.
  • Figure 1 also shows a hot forming and press hardening tool 13, shown here in particular as a double-sided tool. This means that with one closing movement two components are formed and press hardened at the same time will. A tool that falls four times can preferably also be set.
  • the contact heating station 9 can also be designed to be double, preferably quadruple.
  • Figure 2 shows an alternative design variant Figure 1
  • a zone furnace 15 is used here.
  • the zone furnace 15 has a first zone 16 with a higher temperature, in particular greater than or equal to AC3 temperature, and a second zone 17 with a lower temperature, the lower temperature corresponding to the intermediate cooling temperature +/- 50 ° C.
  • a bulkhead 18 or the like can be arranged so that the board 8, which is at the intermediate cooling temperature, is correspondingly tempered in areas different from one another. This also produces a partially tempered blank 12 with an area of the first type 10 and an area of the second type 11, which is then hot-formed and press-hardened.
  • the zone furnace 15 does not have to be a two-zone furnace; it can also be designed as a multiple zone furnace, depending on the geometric specification of the position of the areas of the first type 10 and second type 11.
  • the zone furnace 15 can be operated as a continuous furnace. However, it can also be designed as a multi-storey oven, in particular to save space. It can also be designed as a multi-storey continuous furnace.
  • the furnace particularly preferably has a significantly higher interior temperature, in particular greater than 1000 ° C.
  • Figure 3 shows an illustration of the areas of the first and second type 10, 11 and a transition area 19 in between.
