Definitions

  • the invention relates to a method and a device for producing hardened steel components.
  • Hardened steel components have the advantage, particularly in the body shop of motor vehicles, that their outstanding mechanical properties make it possible to create a particularly stable passenger cell without having to use components that are much more massive and therefore heavier with normal strengths.
  • types of steel which can be hardened by quench hardening are used.
  • types of steel are, for example, boron-alloyed manganese carbon steels, the most widely used here being 22MnB5.
  • other boron-alloyed manganese carbon steels are also used for this purpose.
  • the steel material In order to produce components hardened from these types of steel, the steel material must be heated to the austenitizing temperature (> AC 3 ) and wait until the steel material is austenitized. Depending on the required degree of hardness, partial or full austenitization can be achieved here.
  • a sheet steel blank is separated from a steel strip, e.g. cut or punched and then deep-drawn into the finished component in a conventional, for example five-step deep-drawing process.
  • This finished component is dimensioned slightly smaller in order to compensate for a subsequent thermal expansion during austenitizing.
  • the component produced in this way is then austenitized and then placed in a form hardening tool, in which it is pressed, but not or only very slightly deformed, and the heat flows from the component into the pressing tool as a result of the compression, at a rate that is above the critical hardening speed Speed.
  • the further method is the so-called press hardening, in which a plate is separated from a sheet steel strip, bsp. is cut or punched, then the blank is austenitized and the hot blank is formed at a temperature below 782 ° C in a preferably one-stage step and at the same time cooled at a rate above the critical hardening speed.
  • metallic corrosion protection layers can be used, e.g. plates provided with zinc or an alloy based on zinc can be used.
  • Press hardening is also known as an indirect process and press hardening as a direct process. The advantage of the indirect process is that more complex workpiece geometries can be implemented.
  • the advantage of the direct process is that a higher degree of material utilization can be achieved. However that is achievable component complexity is lower, especially in the one-step forming process.
  • First-order micro-cracks are attributed to the so-called liquid metal embrittlement. It is believed that liquid zinc phases during forming, i.e. While tensile stresses are applied to the material, they interact with the remaining austenite phases, as a result of which microcracks with depths of up to several 100 ⁇ m are generated in the material.
  • the applicant has succeeded in preventing these first-order microcracks by actively or passively cooling the material between removal from the heating furnace and before the start of the hot forming process to temperatures at which there are no longer any liquid zinc phases. This means that the hot forming takes place at temperatures below approx. 750 ° C.
  • the second-order microcracks have so far not been manageable in hot forming despite pre-cooling and also arise at hot forming temperatures below 600 ° C.
  • the crack depths here are up to a few 10 ⁇ m.
  • a method and forming tool for hot forming press hardening of workpieces made of sheet steel is known, and in particular of galvanized workpieces made of sheet steel.
  • the die used for hot forming and press hardening should be coated with a liquid material in its drawing edge area defined by a positive drawing radius or provided with an insert that has a thermal conductivity that is at least 10 W / (mx K) lower than the thermal conductivity of the section of the die adjacent to the drawing edge area, which comes into contact with the workpiece during hot forming and press hardening.
  • the surface of the material applied in the drawing edge area or the arranged insert part facing the workpiece should have a transverse dimension extending over the drawing edge that is in the range of 1.6 to 10 times the positive drawing radius of the die. This is intended to improve the flow properties of workpieces made of sheet steel during hot forming and thus considerably reduce the risk of cracks occurring during hot forming of workpieces made of sheet steel, preferably galvanized steel blanks. With such a tool, however, microcracks of the second type cannot be avoided.
  • a tool for a press hardening tool is known, the shaping surface of the tool being microstructured in some areas by two micro-depressions made in the mold surface.
  • the effective contact area for the deformation of a blank between the mold surface with a blank on the Area portions located between the depressions are limited to four. This is intended to reduce friction.
  • a method and a device for producing a partially hardened molded part comprising the following steps: heating a semifinished product to a hardening temperature, hot forming of the heated semifinished product in a combined hot forging cutting device to form a three-dimensional molded part, trimming of the molded part in the combined Hot forming cutting device and partial press hardening of the molded part.
  • molded parts can be hot formed, trimmed and partially hardened in one step.
  • a post-processing a separate trimming process in a separate trimming tool can be omitted. In this way, undesired changes in terms of shape and structure of the molded parts can be minimized.
  • the object of the invention is to avoid microcracks of the second type in directly hot-formed, ie press-hardened, components.
  • VME vapor metal embrittlement
  • second order microcracks are to be avoided, with the largest possible working window in terms of material and temperature being retained and the implementation being inexpensive. With at least the same throughput time, there should be no increase in cycle time or throughput reduction in component production.
  • the zinc vapor occurring in the tensile stressed areas is either discharged or blown off by gas flows (convection) or is sufficiently diluted.
  • zinc can be rapidly converted into a stable compound such as zinc oxide or ZnJ2 through the admission of fluids.
  • the steel can also be protected against second-order microcracks by producing a protective layer such as an oxide layer by supplying a fluid. All the measures described have shown that microcracks are significantly reduced.
  • gaseous oxygen-containing fluids such as air or oxygen, for example, since these cannot contaminate the tool excessively or also any undesired massive cooling effect such as by ex.
  • Water can be more easily regulated by controlling the temperature of the fluid.
  • the avoidance of the second-order microcracks is ensured by the fact that in the area of the positive radii, i.e. in the area of the drawing edges of the die and / or the male part in the drawing direction, there is a recess adjacent to the drawing edge or other contact areas outside the positive radii / drawing edge, which is dimensioned so that on the one hand the deep drawing is not impaired or the board or the workpiece becomes wavy and on the other hand is dimensioned so that the heat flow, which is necessary for the hardening, is also not significantly impaired.
  • the clearances are dimensioned in such a way that they represent a reservoir for oxygen in such a way that sufficient oxygen reaches the pulling plate or the material to supply the released zinc phases or zinc iron phases with oxygen for oxidation.
  • the recess acts as a fluid reservoir in particular for oxygen, but this reservoir can also contain other fluids, such as water or nitrogen. If these are filled with a noble gas or, in particular, are also continuously flushed with it, they do not act through oxidation but rather through dilution or removal of the zinc vapor that occurs.
  • the recesses on the tool side are advantageously continuously fed with fluids containing oxygen during the forming process, for example through suitable access openings, whereby a flow cushion can advantageously be formed.
  • the tool cavity can be rinsed with a fluid, in particular an oxygen-containing fluid, which is then present in the recesses.
  • an oxygen-containing fluid are air as well as water i.e. these can be supplied in liquid or gaseous form.
  • the drawing edge region 1 or region of a positive radius 1 is arranged on a molding tool and has two workpiece-side surfaces 3, 4 which meet in the region of a drawing edge or a positive radius 2.
  • a recess 5 according to the invention is arranged in a surface 4 following the drawing edge 2 in the drawing direction.
  • the recess 5 is dimensioned in such a way that the remaining thickness of the drawing edge 2 between the surface 3 and the recess 5 approximately corresponds to its radius in order to offer a sufficient support effect for the material to be drawn.
  • the recess 5 has a height between the drawing edge 2 and the surface 4 which is approximately 25 to 35 mm, with a depth of 5 to 9 mm.
  • Figure 2 is instead of a larger recess 5 adjacent to Drawing edge 2, and leaving this in the thickness already described, introduced a groove 6 into surface 4.
  • the groove 6 has a height between the surface 4 and the drawing edge 2, which is approximately 8 to 12 mm, with a depth of 5 to 9 mm.
  • the grooves 7 or slots 7 instead of a continuous recess 5 in the area of the wall 4 adjacent to the drawing edge 2, there is a plurality of grooves 7 running in the drawing direction, the grooves 7 or slots 7, for example, having a slot width of 4 to 8 mm and a slot spacing of 7 up to 11 mm, so that the remaining webs have a width of 1 to 5 mm.
  • the grooves 7 or slots 7 here also have a depth of 5 to 9 mm.
  • the recesses 5, the groove 6, the slots 7 can be on the rear side, i.e. be supplied with an oxygen-containing fluid from the tool, by means of feeds and correspondingly drilled lines, in order, if necessary, to further increase the oxygen partial pressure in the area of the recesses 5, grooves 6 and slots 7.
  • the mold cavity can also be flushed with an oxygen-containing fluid so that there is always enough oxygen reservoir in the clearances 5, grooves 6 and slots 7 is.
  • the 20MnB8, 22MnB8 and other manganese-boron steels are also used - especially in the direct press hardening process.
  • the remainder is iron and impurities caused by the melting process, the alloy elements boron, manganese, carbon and optionally chromium and molybdenum being used as conversion retarders in such steels.
  • the remainder is iron and impurities from the melting process.
  • the remainder is iron and impurities from the melting process.
