Definitions

  • the invention relates to a method for producing a metal component with adjoining sections of different material properties.
  • methods of this type are used to produce by press hardening, for example, manganese-boron steels components that have a uniform hardness profile of up to 1,500 MPa. Due to their low ductility remaining after the hardening process, components made of such steels are usually first preformed, then heated to austenitizing temperature and then rapidly cooled in a mold under high pressure. The parts obtained in this way, in addition to their high hardness on a good dimensional stability.
  • a hardened sheet metal profile can be produced by first forming an intermediate shape from a sheet metal blank, then heating this sheet metal profile to hardening temperature and finally cooling the heated sheet metal profile in a device similar to a deep drawing tool under the effect of a predetermined pressure.
  • the intermediate form produced in the first step of the method already corresponds approximately to the final shape of the component to be produced.
  • the device used for carrying out the known method has channel-like cooling arrangements, which, depending on the heat to be dissipated, are flushed through by oil, water, ice-water or saline solution. The cooling arrangements can be controlled separately from each other to form zones with mutually different degrees of hardness on the finished component.
  • the invention proposes a method for producing a metal component with adjoining sections of different material properties, in which a heated to a forming temperature sheet metal element is formed in a forming tool into a final molded component, wherein the forming a tempering device for adjusting the temperature has at least one of its coming into contact during forming with the sheet metal element portions, and in which the forming speed is controlled in consideration of the duration with which the temperature-controlled portion of the forming tool is in contact with each adjacent thereto portion of the sheet metal element.
  • the speed at which the transformation of the respectively processed sheet metal element takes place in its final shape so adjusted that with the tempered area of the tool, which have a relation to the adjacent sections different temperature, within an optimal for the desired work result
  • Period of time come into contact with the zones of the sheet metal element to be treated separately and that this contact is maintained over an equally optimal period taking into account the other general forming conditions.
  • the sheet metal element can be heated to a forming temperature according to the invention, from which it starts with a correspondingly rapid cooling to form hardened structures.
  • the tempering device is designed as a cooling device, which cools its respectively assigned section of the forming tool to such a low temperature that the zone of the sheet metal element in contact with this cooled section is quenched with a speed sufficient for the formation of the desired hardened structure.
  • the tempering device provided according to the invention can be designed as a heater be holding the portion of the tool, which is associated with the less hard zone of the finished sheet metal component, at such a high temperature that a contact of the sheet with this section a relatively soft structure is maintained.
  • tempering devices If a plurality of tempering devices are present, then specifically cooled and heated sections of the tool can be arranged closely adjacent to one another with the aim of minimizing the spread of undefined compound areas at the transition between a zone of high hardness and its neighboring surroundings in the finished sheet metal part and thus to produce perfectly precisely defined zones with different material properties in the finished component.
  • the inventively provided coupling of the forming speed of the position and propagation of the generated in the finished component zones of different material properties is in this context of particular importance.
  • the forming speed can be selected according to the invention such that the zone in question comes into contact with the strongly cooled section of the tool as quickly as possible.
  • the forming speed is reduced, for example, when a particular zone of the component is to cool particularly slowly in order to produce a softer microstructure there.
  • all sheet metal elements made of metal materials are suitable for the application of the method according to the invention, the structure of which changes when heated or cooled.
  • the method according to the invention can be used particularly advantageously for sheet metal elements which consist of steel.
  • the advantages of the invention can be used particularly targeted.
  • the sheet metal element used as the starting material in the method according to the invention is a flat sheet metal blank.
  • the heated sheet metal element is finished, for example, finished in the form of a deep-drawing process in the forming tool.
  • the targeted, locally limited cooling or heating treatment of the zones of the sheet metal element in which the special properties are to be generated takes place in the forming tool.
  • a further advantage of the procedure according to the invention is that they are particularly suitable for processing sheet metal elements having regions of different thickness.
  • the invention allows the formation of the desired, localized zones with certain material properties, which allow the forming speed and the respective temperature of the tool to adapt to the non-uniform thickness of the sheet metal element, that an optimal work result is obtained.
  • This has a particularly advantageous effect when the sheet metal element is composed of different, materially joined together, in particular by welding, sheet metal pieces.
  • Such sheet metal elements are commonly referred to as "tailored blanks". They are composed, for example, of pieces of sheet metal whose thickness or material properties, such as hardness and toughness, are adapted to the stresses to which the product produced from the tailored blank is exposed in practical use.
  • the forming tool can be any type of tool which, taking into account the respective shaping of the component to be produced, is suitable for exerting the required forming and pressing forces on the respective deformed sheet metal element.
  • Particularly suitable for this purpose are those forming tools which have a die and a die that can be set in the die for forming.
  • the inventive method is particularly suitable for the production of body parts, which in practical Use are exposed to changing loads.
  • spring strut receptacles can be produced particularly well, in which, for example, high strengths are required in the region of the strut tower, while higher extensibilities are required in the region of the flanks of the receptacles.
  • a purely martensitic, particularly firm structure can be specifically produced in the region of the spring strut dome by rapidly cooling this region during the forming process according to the invention and at a high cooling rate.
  • Another particularly advantageous application of the method according to the invention is the production of crash-relevant vehicle components which, in the event of a collision, must have a high energy absorption capacity and at the same time optimum strength.
  • the invention makes it possible by targeted heating of the forming tool in certain sections in the finished component to form zones in which particularly high residual strains are ensured.

  • the forming tool 1 comprises a punch 4, which determines the inner shape of the component B to be produced.
  • the punch 4 can be moved by means of a setting device, not shown, from a starting position (FIG. 1) remote from the die 2 into its end position, in which it is completely retracted into the recess 3 of the die 2 (FIG. 3).

  • the lower edge surfaces 11,12 of the edge regions 9,10 are connected in a horizontal orientation to the side surfaces 6,7 of the punch 4.
  • not preformed sheet metal elements E are processed in the illustrated embodiment, which are in the manner of tailored blanks of two welded together, consisting of a steel material sheet metal parts Tl, T2 assembled.
  • the first sheet metal part 1 is thinner than the second sheet metal part T2 for weight savings.
  • cooling channels 13 are introduced into the stamp.
  • the cooling channels 13 are part of a further not shown as a cooling device first tempering. Depending on the respectively required degree of cooling, the cooling channels 13 are traversed by water, ice-water, a frozen salt solution, liquid nitrogen or another cooling medium which is suitable for the rapid removal of large amounts of heat.
  • Formed tempering which is also not shown here in detail further. Through the channels 16 The tempering is promoted a cooling oil, which causes a moderate cooling of the die in this area.
  • the sheet metal element E is first heated to austenitizing temperature in an oven, not shown here. Subsequently, the sheet metal element E is placed in the forming tool 1, so that it lies with its edge on the upper side of the die 2. If this is necessary for the further deformation of the sheet metal element E carried out in the forming tool 1, hold-downs, not shown, are now used, which hold down the sheet metal elements E in its edge region during the subsequent forming.
