Definitions

  • the invention relates to a method for producing hardened components from sheet steel.
  • the most widely used raw material in bodybuilding is steel. With no other material can be in such large areas cost components with different material properties available.
  • a perspective, in particular for bodies in the automotive industry are components made of steel sheet with a strength depending on the alloy composition in a range of 1000 up to 2000 MPa.
  • a scale layer forms on the surface. This is removed after forming and cooling. This is usually done with sandblasting. Before or after this descaling, the final trimming and the insertion of holes is carried out. If the final trimming and the insertion of the holes are carried out before sandblasting, it is disadvantageous that the cut edges and hole edges are affected. Irrespective of the order of the processing steps after curing, it is disadvantageous in the case of final scaling by sandblasting and comparable methods that the component is often distorted as a result. After said processing steps, a so-called piece coating with a corrosion protection layer takes place. For example, a cathodically effective corrosion protection layer is applied.
  • the post-processing of the cured component is extremely expensive and is subject to very high wear due to the hardening of the component. Further is disadvantageous that the piece coating usually causes a corrosion protection, which is not particularly pronounced. In addition, the layer thicknesses are not uniform, but fluctuate over the component surface.
  • this method it is also known to cold form a component from a sheet metal blank and then heat to the Austenitmaschinestemperatur and then cool rapidly in a calibration tool, wherein the calibration tool is responsible for the component, which is warped by the warm-up, with respect the reshaped areas are calibrated. Subsequently, the post-processing described above. Compared with the method described above, this method allows more complex geometries, since essentially only linear shapes can be produced during simultaneous forming and hardening, but complex shapes can not be realized in such forming processes.
  • a method for producing a hardened steel component in which a sheet of hardenable steel is heated to the hardening temperature and then placed in a shaping device in which the sheet is formed into the desired final shape, wherein simultaneously cooled rapidly during the forming, so that a martensitic or bainitic structure is obtained while the sheet remains in the molding apparatus.
  • a starting material for example, a boron-alloyed carbon steel or carbon manganese steel is used.
  • the deformation is preferably a compression but can also be used with other methods.
  • the forming and cooling should preferably be carried out and carried out so rapidly that a fine-grained martensitic or bainitic structure is obtained.
  • From the EP 1 253 208 A1 is a method for producing a hardened sheet metal profile from a board, which is hot formed and cured in a pressing tool to the sheet metal profile known.
  • On the sheet metal profile projecting reference points or collars are generated from the plane of the board, which serve for positional orientation of the sheet metal profile in subsequent manufacturing operations.
  • the collars should be formed during the forming process of non-perforated areas of the board, the reference points are generated in the form of marginal stampings or as enforcements or collar in the sheet metal profile.
  • the hot forming and hardening in the pressing tool should generally have advantages due to the efficient by the combination of forming and tempering process in a tool operation. Due to the clamping of the sheet metal profile in the tool and due to thermal stresses, however, it should come to not exactly predeterminable delay on the component. This can adversely affect downstream manufacturing operations, which is why the reference points are created on the sheet metal profile.
  • a method of making steel sheet products wherein a steel sheet product is molded in a pair of cooled tools while hot and hardened into a martensitic structure while still in the tool so that the tools act as a fixture during the process Hardening serve.
  • the steel shall be kept in the mild steel area, with inserts in the tools used to prevent rapid cooling and thereby a martensitic structure in these areas.
  • the same effect should also be achieved by recesses in the tools, so that a gap between the steel sheet and the tools occurs.
  • this method is disadvantageous because of the significant delay that can occur here, the present method for press hardening of components with more complex structure is disabled.
  • a method for producing locally reinforced sheet metal formed parts wherein the base sheet of the structural part connected in a flat state with the reinforcing sheet and defined this so-called patched composite sheet is then formed together.
  • the patched composite sheet is heated to at least about 800 to 850 ° C before forming, quickly inserted, rapidly formed in the hot state and then with mechanical maintenance of the forming state by Contacting with the internally forced-cooled forming tool defines cooled.
  • the extent relevant temperature range 800 to 500 ° C is to be traversed with a defined cooling rate.
  • the step of connecting reinforcing sheet and base sheet should be readily integrated in the forming process, wherein the parts are brazed together whereby an effective corrosion protection at the contact zone can be achieved at the same time.
  • the tools are very expensive, in particular due to the defined internal cooling.
  • a method and a device for pressing and hardening a steel part are known.
  • the aim is to press and harden sheet steel pieces in the form of avoiding the disadvantages of known methods, in particular that parts made of steel sheet are produced in successive separate steps for compression molding and hardening.
  • the hardened or quenched products to the desired shape show a delay, so that additional steps are required.
  • it is intended to place a piece of steel, after the piece has been heated to a temperature attaining its austenitic condition, between a pair of cooperating mold members, whereupon the piece is pressed and at the same time heat is rapidly dissipated from the piece to the mold pieces.
  • the mold parts are kept at a cooling temperature throughout the process, so that a quenching effect is exerted on the piece under a molding pressure.
  • a method of producing a part having very high mechanical properties is known, wherein the part is to be produced by punching a strip from a rolled steel sheet, and in particular a hot rolled and coated part is coated with a metal or metal alloy covering the surface of the steel to protect, wherein the steel sheet is cut to obtain a steel sheet preform, the steel sheet preform is cold or hot formed and is either cooled and hardened after hot working or heated after cold working and then cooled.
  • An intermetallic alloy is supposed to be on the surface before or after
  • this intermetallic mixture can also have a lubricating function. Subsequently, the supernatant material is removed from the molding.
  • the coating should generally be based on zinc or zinc-aluminum. In this case, a steel can be used which is electrolytically galvanized on both sides, with an austenitization to take place at 950 ° C. This electrolytically galvanized layer is completely converted into an iron-zinc alloy during austenitisation. It is stated that during forming and while being held for cooling, the coating does not hinder the heat flow through the tool and even improves heat dissipation.
  • this document proposes as an alternative to an electrolytically galvanized tape to use a coating of 45% to 50% zinc, balance aluminum.
  • a cathodic corrosion protection is practically no longer available.
  • such a layer is so brittle that cracks occur during forming.
  • a coating with a mixture of 45 to 50% zinc and 55 to 45% aluminum also exhibits no significant cathodic corrosion protection. While it is claimed in this reference that the use of zinc or zinc alloys as a coating would provide galvanic protection even to the edges, this can not be achieved in practice. In practice, the coatings described can not even achieve sufficient galvanic protection in the surface.

  • the sheet should be provided with a metal or a metal alloy, which ensures the protection of the surface of the sheet, then the sheet is subjected to a temperature increase for the forming, then a transformation of the sheet are performed and the part are finally cooled.
  • the coated sheet is to be pressed while hot and the part formed by the deep drawing to be cooled to be cured and that at a speed which is higher than the critical curing rate.

  • the applied coating should consist in particular of aluminum or an aluminum alloy, whereby not only an oxidation and decarburization protection, but also a lubricating effect should result.
  • the steel used should be an air-hardening steel, which may be heated under a protective gas atmosphere in order to avoid scaling during heating. Otherwise, a scale layer is descaled in front of the mold component after hot working of the mold component.
  • the component blank is shaped close to the final contour, "near net shape" being understood to mean that those parts of the geometry of the finished component which are associated with a macroscopic flow of material completely into the component blank after completion of the cold forming process are formed. After completion of the cold forming process Thus, for the production of the three-dimensional shape of the component only slight form adjustments to be necessary, which require a minimum local material flow.
  • the object of the invention is to provide a method for producing hardened components made of sheet steel, which is simple and quick to carry out and which makes it possible to produce hardened components made of sheet steel in particular steel sheet with a cathodic corrosion protection dimensionally accurate and without finishing such as descaling and sandblasting.
  • the forming of the components as well as the trimming and punching of the components is carried out essentially in the uncured state.
  • the relatively good deformability of the particular material used in the unhardened state allows the realization of complex component geometries and replaces expensive subsequent trimming in the cured state by significantly less expensive mechanical cutting operations before the hardening process.

  • the processed boards may be rectangular, trapezoidal or shaped boards. All can be used for cutting the boards known cutting processes are applied. Preferably, cutting processes are used which do not introduce heat into the sheet during the cutting process.
  • the final trimming is carried out in said conventional tools.
  • the molded part which has been formed in the cold state, is made smaller by 0.5 to 2% than the nominal geometry of the end component, so that the thermal expansion during heating is thereby compensated.
  • the moldings produced by the processes mentioned should be cold formed, the dimensions of which are within the required by the customer for the finished part tolerance field. If larger tolerances occur in the aforesaid cold forming, they may be partially corrected later, minimally, during the molding hardening process, which will be discussed later.
  • the tolerance correction in the form hardening process is preferably performed only for shape deviations. Such form deviations can thus be corrected in the manner of a hot calibration.
  • the correction process should as far as possible be limited to one bending operation, wherein cutting edges that are dependent on the amount of material (in relation to the forming edge) should not and can not subsequently be influenced, ie, if the geometry of the cutting edges in the parts is not correct , in the form hardening tool no correction can be made.
  • the tolerance range with respect to the cutting edges corresponds to the tolerance range during the cold forming and the shape hardening process.
  • no distinctive folds should be present within a molded part, because then the uniformity of the printed image and a uniform shape hardening process can not be guaranteed.
  • the deformed and cut part is heated to an annealing temperature above 780 ° C, especially 800 ° C to 950 ° C, and held at that temperature for a few seconds to a few minutes, at least until a desired austenitization has occurred ,
  • the component is subjected to the inventive form hardening step.
  • the component is inserted into a tool within a press, wherein this mold hardening tool preferably corresponds to the desired final geometry of the finished component, that is to say the size of the cold-formed component including the thermal expansion.
  • the shape-hardening tool has a geometry or contour that substantially corresponds to the geometry or contour of the cold-forming tool, but is 05 to 2% larger (with respect to all three spatial axes).
  • the aim is to form-hardening a full-surface fit between the mold hardening tool and the workpiece or component to be cured immediately after de close the tool.
  • the molding is placed at a temperature of about 740 ° C to 910 ° C, preferably 780 ° C to 840 ° C in the mold hardening tool, the previous cold forming as already considered takes into account the thermal expansion of the part at this EinlegeTemperatur range.
  • an insertion temperature of 780 ° C to 840 ° C can be achieved even if the annealing temperature of the cold-formed component between 800 ° C and 850 ° C, since the special zinc coating according to the invention - compared to uncoated Sheet metal - reduces rapid cooling.
  • This has the advantage that the parts must be heated less high and in particular a heating to over 900 ° C can be avoided. This in turn results in an interaction with the zinc coating since the zinc coating is less affected at somewhat lower temperatures.
  • a part is first removed by a robot from a conveyor belt and placed in a marking station, so that each part can be traceably marked before it is hardened. Then the robot places the part on an intermediate carrier, wherein the intermediate carrier passes over a conveyor belt in an oven and the part is heated.
  • a continuous furnace with convection heating for example, a continuous furnace with convection heating is used.
  • any other heat aggregates or ovens can be used, in particular ovens, in which the moldings are heated electromagnetically or with microwaves.
  • the molding passes through the furnace on the support, the support being provided so that the corrosion protection coating is not transferred to rolls of the continuous furnace or is rubbed off by it during heating.
  • the parts are heated to a temperature which is above the austenitizing temperature of the alloy used.
  • the maximum temperature of the parts is kept as low as possible, which, as already stated, is made possible in particular by the part being cooled more slowly by the zinc layer.
  • a robot takes the part, depending on the thickness at 780 ° C to 950 ° C, especially 860 ° C to 900 ° C from the oven and places it in the mold hardening tool.
  • the molded part loses approximately 10 ° C. to 80 ° C., in particular 40 ° C., whereby the insertion robot is preferably designed such that it inserts the part accurately into the mold hardening tool at high speed.
  • the molding is The robot places it on a part lifter and then quickly shuts down the press, displacing the lifter and fixing the part. This will ensure that the component is properly positioned and guided until the tool is closed.
  • the part still has a temperature of at least 780 ° C.
  • the surface of the tool has a temperature of less than 50 ° C, whereby the part is rapidly cooled to 80 ° C to 200 ° C. The longer the part is held in the tool, the better the dimensional accuracy.
  • the tool is subjected to thermal shock, wherein the method according to the invention makes it possible to design the tool with respect to its base material for a high thermal shock resistance, in particular if no forming steps are carried out during the mold hardening step.
  • the tools In conventional methods, the tools must also have a high abrasion resistance, but in the present case does not play a significant role and thus reduces the cost of the tool.
  • a robot takes the parts out of the press and places them on a rack, where they continue to cool down.
  • the Cooling may, if desired, be accelerated by additional blowing on of air.
  • the inventive mold hardening without appreciable forming steps and with a substantially full-surface fit of the tool and the tool piece, it is ensured that all areas of the workpiece are defined and uniformly cooled on all sides.
  • a comprehensible defined cooling takes place only when the forming process has progressed so far that the material rests against both mold halves.
  • the material is preferably immediately on all sides positively against the mold halves.
  • An additional advantage is the low stress on the mold hardening tool due to the complete cold end geometry. This can be a much higher Tool life and dimensional accuracy can be achieved, which in turn means a cost reduction.
  • the form hardening is performed so that a concern of the workpiece to the mold halves or a positive connection between the workpiece and tool only at the narrow toleranced areas such as the cutting and shaping edges, the forming surfaces and optionally in the areas of the Lochndues done.
  • the positive connection in these areas is brought about such that these areas are held and clamped so securely that less tightly tolerated areas can hot working in the tooling process, without the already dimensionally accurate and tolerated narrowly tolerated areas are adversely affected and warped in particular.
  • the not tightly tolerated areas either by not applying one or both mold halves slower to cool down and reach there by the slower cooling other degrees of hardness, or to achieve a desired hot forming in these areas, without the tightly tolerated areas are affected. This can be done for example by additional stamp in the mold halves. It is essential, as already stated, however, also in this preferred embodiment, that the tightly tolerated areas remain unaffected in terms of shape hardening with respect to forming.
