Definitions

  • the invention relates to a method for producing a press-hardened component according to the preambles of independent claims 1 and 2.
  • Such a material is, for example, the precoated boron steel marketed by Usinor under the trader Usibor 1500.
  • the steel is provided with an AISi coating which, among other things, exhibits advantageous corrosion-inhibiting properties in the course of the subsequent heat treatment.
  • the component is subjected to a preforming cut or a trimming step before the actual hot forming.
  • a preforming cut or a trimming step before the actual hot forming.
  • This is for example in the DE 101 49 221 C1 described.
  • a method may cause corrosion problems because a commonly applied tape coating will be damaged during preforming.
  • the object of the invention is to specify a press-hardened component as well as a production method for press-hardened components, which enables reliable corrosion protection for precoated, hot-workable steels.
  • a first embodiment of the method according to the invention for the production of press-hardened components comprises the following method steps: a component blank is formed from the precoated semi-finished product by a cold-forming method, in particular a drawing method; the component blank is trimmed on the edge on a part of the production approximately corresponding boundary contour; the trimmed component blank is heated and press-hardened in a hot-forming tool; the press-hardened component blank is coated in a coating step with a corrosion-protective layer.
  • this embodiment of the invention makes it possible to design the component manufacturing process in such a way that it is possible to dispense with the procedurally complex and costly final trimming of the hardened component.
  • the edge regions are therefore already cut in the uncured state of the component and not only - as usual in hot forming usual - after the heating and hardening process.
  • By pruning the workpiece already in the soft state significantly lower cutting forces are required than for cold-cutting hardened materials, resulting in reduced tool wear and a reduction in the maintenance cost of the cutting tools.
  • the risk of rapid cracking due to the high notch sensitivity of these materials is significantly reduced when trimming the high strength material in the uncured state.
  • the pre-coating provided on the semifinished product avoids scaling of the trimmed component blank in the hardening process, and the requirements for an inert atmosphere during curing can be reduced. In addition, the pre-coating prevents decarburization of the material during curing.
  • a further layer which protects against corrosion is applied, so that the component is completely coated, ie also at the edges.
  • the following method steps are carried out: the semifinished product precoated with a first layer is heated and press-hardened in a hot-forming tool; the component blank produced in this way is trimmed at the edge to a boundary contour corresponding to the component to be produced; the press-hardened, cut component blank is coated in a coating step with a second corrosion-protective layer.
  • the trimming of the cured component is preferably carried out by means of a laser or water jet cutting method, by which a high-quality trimming of the component edges can be achieved.
  • the subsequent application of the second corrosion protection layer ensures that the component is also protected against corrosion in the area of the trimmed edges.
  • a corrosion-protective layer of zinc can be applied in a coating process that can be suitably integrated into a production process.
  • the layer is applied to the press-hardened component blank by a thermal diffusion method, a readily controllable method can be used, with which preferably a layer of zinc or a zinc alloy can be applied, which is also suitable for complex component geometries and edge layering is.
  • the layer thickness can be adjusted selectively between a few microns and over 100 microns.
  • a thermal load of the component is low.
  • Components can be used regardless of their size, dimensions, Configuration, complexity and weight are coated.
  • a cleaning prior to the coating step with a dry cleaning, in particular blasting of the press-hardened component blank with glass particles or zinc particles, can be omitted, since the precoating substantially prevents scaling of the component blank during hot forming. This saves a process step; In addition, it is avoided that a small, but possibly disturbing component distortion occurs by blasting the components with particles.
  • a good adhesion between the two coatings results.
  • the second layer applied to the first layer of the precoat provides edge coating and coating of those areas where the first layer of the precoat e.g. was chipped in the pre-forming or cracked due to excessive friction.
  • the component blank is cleaned of residues after the coating step, for example with ultrasound, and passivated, a surface is formed which gives a good primer for coatings, in particular primers of paints or coatings themselves.
  • the component blank is tempered after the coating step. It is particularly advantageous if the component blank is coated with a zinc-containing layer, since an oxide is formed on the surface, which is suitable as a primer.
  • a press-hardened component in particular a body component, from a semifinished product of unhardened, hot-workable steel sheet, which has been produced according to at least one embodiment of the method according to the invention, is particularly suitable for mass production with corresponding series production and combines a favorable weight reduction of the component with excellent corrosion protection.
  • FIGS. 1a to 1e schematically show an inventive method for producing a spatially shaped, press-hardened component 1 from a semifinished product 2.
  • a board 3 is used as a semifinished product 2, which is cut out of a developed coil 5.
  • a composite sheet are used, as for example in the DE 100 49 660 A1 is described and which consists of a base plate and at least one reinforcing plate.
  • a Taylored Blank can be used, which consists of several welded together sheets of different material thickness and / or different material properties.
  • the semifinished product 2 may be a three-dimensionally shaped sheet-metal part produced by any forming process which is to undergo further deformation and a strength and / or rigidity increase with the aid of the method according to the invention.
  • the semifinished product 2 consists of an unhardened, hot-forming steel sheet.
  • a particularly preferred material is a boron-containing tempering steel, e.g. Usibor 1500, Usibor 1500 P or Usibor 1500 PC, which are distributed by the company Usinor under these trade names.
  • the board 3 ( Fig. 1a ) are cut out of a unwound and straightened portion of a coil 5 from a precoated, thermoformable sheet.
  • the coating is a coating of aluminum or an aluminum alloy, in particular a silicon-containing aluminum alloy AlSi.
  • the thermoformable material is at this time in an uncured state, so that board 3 easily using conventional mechanical cutting means 4, for example, a scissors, can be cut out.
  • the cutting of the board 3 is advantageously carried out with the help of a platinum press 6, which ensures an automated feed of the coil 5 and an automatic punching and removal of the cut-out board 3.
  • board 3 is in 2a shown in a schematic perspective view.
  • the cut-out blanks 3 are deposited on a stack 7 and fed in stacked form to a cold-forming station 8 (FIG. Fig. 1b ).
  • a component blank 10 is formed in a second process step II from the circuit board 3 by means of the cold forming tool 8, for example a two-stage deep drawing tool 9.
  • the board 3 has edge regions 11 which protrude beyond an outer contour 12 of the component 1 to be molded.
  • the component blank 10 is formed close to the final contour.
  • close-to-net shape should be understood to mean that those parts of the geometry of the finished component 1 which are accompanied by a macroscopic flow of material are completely formed in the component blank 10 after the cold-forming process has been completed. After completion of the cold forming process, only slight conformations of shape are required to produce the three-dimensional shape of the component 1, which require a minimum (local) material flow; the component blank 10 is in Fig. 2b shown.
  • the near-net shape shaping can take place in a single deep-drawing step, or it can take place in several stages ( Fig. 1b ).
  • the component blank 10 is in a Cutting device 15 is inserted and cut there (process step III, Fig. 1c ).
  • the material is still in the uncured state at this time, so trimming can be accomplished by conventional mechanical cutting means 14 such as cutting knives, folding and / or punching tools.
  • a separate cutting device 15 may be provided.
  • the cutting means 14 may be integrated into the last stage 9 'of the deep-drawing tool 9, so that in the last deep-drawing stage 9' in addition to the final shaping of the sheet metal blank 10, the edge trimming takes place.
  • the process steps II and III are integrated in a single processing station, in which the forming and cutting is carried out fully automatically.
  • the removal of the component blank 17 from the processing station can be automated or there may be a manual removal and stacking of the component blanks 17.
  • the trimmed component blank 17 is subjected to hot working in a hot forming area 26, in the course of which it is formed and hardened to a final shape of the component 1.
  • the trimmed component blank 17 is inserted by a manipulator 20 in a continuous furnace 21, where it is heated to a temperature which is above the structural transformation temperature in the austenitic state; Depending on the grade of steel, this corresponds to heating to a temperature between 700 ° C and 1100 ° C.
  • a favorable range is between 900 ° C and 1000 ° C.
  • the atmosphere of the continuous furnace can be rendered inert by the addition of a protective gas, but the precoating of the blanks 3 already prevents at least a full-surface scaling of the blank surface.
  • the uncoated interfaces of the edge contour 12 'of the trimmed component blanks 17 represent only a very small area ratio of the component blank 17, so that adhesion of a layer applied later is virtually unaffected.

This step corresponds to a hardening of the component blank 18 and allows a targeted adjustment of the material strength. Details of such a curing process are eg in the DE 100 49 660 A1 described.
  • the hardened component blank 18 is taken out of the hot forming tool 23 with a manipulator and optionally stacked until further processing.
