Definitions

  • the invention relates to a method and a device for producing a metal component, which is to obtain different strength properties within the same component, according to the preambles of claims 1 and 6, respectively.
  • a motor vehicle B-pillar have a hard central area to maintain high stability and on the other hand at the upper and lower attachment points to the body be ductile, so that in an impact introduced energy can be dissipated, if possible without causing tearing.
  • the different structure formation within a steel material is made use of when choosing different cooling rates.
  • a high cooling rate leads to the predominant formation of hard martensite, while lower cooling rates favor other microstructures such as bainite or the preferred because of their toughness Ferit and perlite.
  • a base body which is subsequently thermoformed in a preferably press-hardening process, can be pushed out of the oven, for example, after being heated to austenitizing temperature with one partial area, which then cools slowly in the air, while the other portion is kept in the oven at austenitizing temperature.
  • the subsequent forming leads at sufficient cooling rate to a hard area (which was left longer in the oven and therefore had Austenitmaschinestemperatur) and a
  • CONFIRMATION COPY softer area which had already cooled a little further in the air and therefore during further cooling by transformation into the microstructure of Ferit, perlite or bainite passes.
  • a corresponding method with additional use of a buffer furnace as a buffer is described, for example, in EP 2 365 100 A2.
  • This method has the disadvantage that only a softer area can be created, a maximum of two, if the oven is very short, so that the component can protrude on both sides.
  • the transition zone between soft and hard area in the finished component is often undesirably large.
  • a buffer oven is shown in EP 2 365 100 A2, which has cooled contact surfaces on which the workpiece can be placed in order to extract heat in some areas.
  • the buffer oven must be specially tailored to the workpiece, which is very expensive.
  • the base body is inserted into the forming tool at a uniform temperature, where it is shaped over differently cooled regions of the tool at different cooling rates.
  • this often leads to warping of the components and thus to high reject rates.
  • a further alternative according to EP 1 180 470 B1 is therefore not to heat certain areas into the austenite by partially covering the base body with a cover placed thereon in the furnace during the first heating before the forming process. This can also be done by partial heat removal during the heating process according to DE 10 2006 018 406 B4.
  • both methods have disadvantages when, for example, coated materials are used. For example, in the case of an AISi coating, thorough heating is required so that alloying and optimum bonding of the layers takes place. If this is not the case, the aluminum coating adheres to the following Forming process often on the tool, resulting in a high tool wear.
  • DE 10 2010 048 209 B3 describes a method in which a board heated to austenitizing temperature is intermediately cooled in a subarea which receives a mixed structure of martensite and bainite in the following forming process.
  • the intermediate cooling which is preferably carried out by integrated cooling plates in the forming tool itself, however, is expensive.
  • the martensite and bainite mixed structure obtained in the subregion is not optimal for many applications due to the high bainite content.
  • the invention is therefore based on the object of specifying a method and a device which avoid the disadvantages of the previously known processes and in particular enable the production of components with more complicated contours between the regions of different strength properties.
  • This object is achieved by a method having the features of claim 1 and a device having the features of claim 6.
  • Claim 15 relates to a shielding device as an inventively essential component of the device according to claims 6 to 14.
  • a metallic base body in particular a sheet steel plate, which may also be coated, is heated to at least austenitizing temperature or made available at this temperature.
  • a region of the base body which can also be composed of several subregions, is shielded against the action of heat by a shielding device accompanying the workpiece, while the base body continues to be subjected to heat.
  • the unshielded area of the body is kept at Austenitmaschinestemperatur while the shielded area controlled below the Austenitmaschinestemperatur but above martensite starting temperature drops, wherein in this component area an average cooling rate below the martensite critical cooling rate prevails, so that the structure of this area after the subsequent forming consists mainly of ferrite and perlite, regardless of the subsequent cooling rate during forming.
  • the cooling of the shielded areas should be done slower than a self-given cooling in air.
  • a cooling rate above the critical for martensite cooling rate is maintained, ie the cooling of the body is so fast that in the previously unshielded area a structure of predominantly martensite is formed.
  • both areas of the base body can be cooled at a cooling rate greater than the critical cooling rate for martensite formation, since a martensite transformation can only occur in the previously unshielded area because of the partial cooling of the shielded area or shielded areas.
  • both coated and uncoated materials can be used as the base body, since the starting temperature above the austenitizing temperature results in a previous alloying of the entire base body, whereby the forming tools are spared.
  • components with complicated contours for the different strength properties can be created, as they can be imaged by the design of the shield.
  • complicated temperature control devices for the forming tool are unnecessary because the deformation can be done with a uniform cooling rate over the entire body, which also avoids the risk of warping of the components when removed from the mold.
  • the shielding takes place contactlessly, at least over the predominant area of the area to be shielded, ie the base body should touch the shielding at as few points as possible. It is particularly advantageous if the base body is mounted on supports, kiln furniture, furnace carriers or the like and the shield is completely contactless with respect to the base body, since then the Shielding is cheaper and almost wear-free.
  • the shielding device is workpiece accompanying and not furnace bonded.
  • the shielding takes place at least partially via radiation shielding, so that the heat radiation in the shielded areas can not penetrate to the base body. This is preferably even the predominant type of shielding.
  • the shield can be subject to an active temperature control, which is realized by a targeted temperature / cooling of the cover. This serves in particular to protect the shield itself, in order to avoid its excessive heating by the radiant heat of the body, the furnace and / or by the heat application of the rest of the body. Since the surface of the shield may preferably be made of aluminum, it is prevented that it melts. But the introduction of heat energy is possible if, for example, the shield for the desired temperature drop is too strong and even slower cooling is desired.
  • a device which has at least one heating unit, or a series main oven, for example a roller hearth furnace, a (multi-layer) chamber furnace or a reciprocating furnace, and a forming tool, in particular a press-hardening tool or a forming press.
  • the heart of the device and therefore claimed separately in claim 15 is a shielding device which has one or more contoured cover elements for shielding the predetermined area of the base body and is designed both in terms of its material and in terms of their functional design so that they in the heating unit can be inserted and stay there with the body, while the body is tempered before forming.
  • the cover (s) are preferably slidably or pivotably attached to the shielding means so as to be according to necessity and intended use can be moved over, under and / or around the area of the body to be shielded.
  • a shielding device does not have to allow different possibilities of movement of the cover elements, since a shielding device designed especially for its geometry is usually produced for each workpiece to be produced, as there is also a separate press hardening mold for each workpiece. Therefore, the furnace itself does not have to be adapted to the workpiece, but only the shielding device accompanying the workpiece.
  • the cover or the elements are preferably held pivotably or displaceably on a guide element of the shielding. In particular, they can be arranged to be closed and reopened in the manner of a mold. This can be done for example via a rotary knob and a toothed rail, which translates the operation of the rotary wheel in a lateral and opposite movement and extension of the cover.
  • the device according to the invention and the shielding device can also be used advantageously in processes if the main body has not yet reached complete austenitizing temperature before being taken into the shielding device, ie thorough heating of the main body has not yet been completed.
  • This can be, for example, at a temperature just below Austenitmaschinestemperatur, eg Austenitmaschinestemperatur minus 30 K.
  • the shielded areas of the body then reach despite austenitmaschine temperature despite ongoing heating, while adjusting itself in the unshielded areas.
  • reduced cycle times can be realized because the Temperianssphasen be shortened.
  • this can be used for uncoated base materials and also for coated base materials whose coating does not require alloy, eg zinc-based coating systems.
  • a self-sufficient heating unit can be provided into which the shielding device can be integrated.
  • the heating to austenitizing temperature and the maintenance of the temperature in the unshielded areas of the body, while the shielded areas are already undergoing a targeted cooling can be decoupled from the main heating unit, which makes sense even if the timing in the different areas takes different lengths.
  • a transition region in which the material properties pass from those of one area to that of the other area is formed on the separating contour of the cover element in the finished workpiece.
  • the methods of the prior art resulted in a mostly relatively large transition region.
  • a very small transitional area of, for example, only 15 to 25 mm can be achieved via the shielding device according to the invention with a sharp-edged contour of the cover elements.
  • this can also be adjusted with the device according to the invention by varying the thickness of the cover element - and thus the shielding effect - in the direction of the transition zones.
  • a thus targeted adjustment of temperature and strength gradients after final shaping and cooling in the forming tool can also be done by varying the distance of the cover to the main body in the shield.
  • the variation of the distance and the thickness of the cover can also be used together.
  • a targeted influencing of the component strength of the component to be produced can also take place, in particular, by the fact that the cover element or the covering element Elements have an active temperature control, in particular an active cooling.
  • the extraction temperature can be adjusted specifically.
  • by such a controllable and controllable time-dependent temperature control in the shielding significantly higher insertion temperatures of the shielded and thus already partially cooled areas of the body when inserted into the forming tool can be selected, thereby reducing both an abrasive and an adhesive tool wear and significantly improves the formability becomes. Increased degrees of deformation are thus also possible in the areas which should have softened properties after the deformation.
  • the shielding device In order to control and, if appropriate, purposefully influence the cooling process during the residence of the base body in the shielding device, it is advantageous if it has an integrated temperature sensor which can be integrated in particular in the cover elements. In addition, the current temperature of the recorded body is to be determined in these areas. If a coupling of the temperature sensor with the active temperature control of the cover, a time-dependent temperature control can be automatically controlled and controlled.
