Definitions

  • the invention relates to a device for forming metal sheets, which has a forming tool with a forming space, wherein the metal sheet in the forming space is partially heated by at least one heating element.
  • the hot forming of metal sheets as such is known, for example by the DE 24 52 486 A1 as well as through the GB 1 490 535 A ,
  • the metal sheets preferably sheet steel blanks, heated in a heat treatment plant, then placed hot in the press tool and reshaped. Still clamped in the press tool, the sheet-metal profile components are hardened.
  • a significant advantage of this approach is that hardened sheet metal profile components can be produced with a complicated shape, and with high dimensional accuracy.
  • thermoformed components especially made of high-strength sheet steel, such as B-pillars, must still be trimmed at the edge in order to comply with the specified dimensional tolerances.
  • many mold components still punched after hot forming. Since the thermoforming process brings about a very hard martensitic microstructure state, a conventional edge / hole trimming of the molded components carried out with cutting knives is very wear-resistant and cost-intensive.
  • Alternative cutting methods, such as trimming by means of laser radiation, are also extremely expensive due to the high system costs.
  • the second possibility is to design the hot forming or hardening process in such a way that a slower cooling during hardening takes place in the areas to be trimmed.
  • This is only possible to a limited extent in the currently used conventional hot forming tools, which are aimed at cooling the moldings as quickly as possible. Suggestions for this are from the DE 197 23 655 A1 known.
  • inserts or additional heating elements are provided in the press tool in order to achieve reduced cooling during hardening in targeted areas, so that these areas have a softer material structure at the end of the process.
  • DE 101 62 441 A1 describes a method for producing motor vehicle components from metal sheets in a forming tool having a mold space, wherein for controlling the material flow mold space areas can be tempered specifically by heat and / or heat dissipation.
  • the particular difficulty is basically to realize very different Abkühlgradienten at the lowest possible transitions between hard and soft zones, ie within a few millimeters of one and the same mold component.
  • the invention is based on the prior art based on the object to provide a system and application technology improved apparatus for forming metal sheets, in particular, very different cooling gradients can be realized in tight spatial limits on the molded part.
  • the main point of the invention is the measure to heat-control the heating element integrated in the forming tool completely or in sections relative to the adjacent walls of the forming tool by means of an insulating layer.
  • the effectiveness of the heating element can be increased with a targeted heat transfer to specific narrow or locally limited areas or zones of the molded component.
  • the influence of the material structure on the molded part can thus be made significantly better. A heat flow into adjacent areas of the forming tool is avoided.
  • the heated in the forming space areas of the mold component cool in the hardening process, so while they are clamped in the forming tool, not from. Only after the deformation tool has been opened do the spots cool at a considerably lower cooling rate in air. Due to the slow cooling rate, no hard martensitic structure is produced in the molded component at the previously heated locations. It can be at these locations a component hardness similar to the unmilled material state achieve, so that downstream processing steps, ie in particular cutting or punching operations, better and higher quality can be performed. Also the used processing tools, like knives or punching tools, are subject to significantly less wear and achieve significantly longer service life.
  • At least one, preferably a plurality of heating elements are integrated in recesses of the forming tool, wherein the heating element is thermally insulated from the adjacent walls of the forming tool by an insulating layer, so that a heat dissipation into the forming tool is avoided and the heat is released primarily only in the direction of the tool surface.
  • the configuration of the heating elements is in particular geometrically tuned in such a way that those areas of the mold component which are intended to remain soft are tempered in a targeted manner.
  • depressions, grooves or similar recesses are provided, in which a heating element is introduced.
  • insulating layer ceramic insulating materials or glass fiber materials can be used. Insulating layers of mica are also suitable for the purpose according to the invention. Since air also has good insulation or thermal insulation properties, the insulating layer can also be formed as an air gap. Also possible is a combination of the insulation of an insulating material and an air gap.
  • a material for the insulating layer is a technical ceramic with a thermal conductivity ⁇ ⁇ 2 W / Km offers.
  • electric heating elements e.g. High-performance heating cartridges, just as conceivable as small pipes through which a hot medium flows. It should be noted that for the electrical heating of large tool areas relatively high power densities must be provided.
  • the heating element is limited by a cover to the forming space.
  • the cover expediently closes off the heating element and the insulating layer toward the shaping space, so that the tool surface on which the sheet metal blank to be formed slides during the forming process is made homogeneous.
  • the cover is made of a material with good thermal conductivity, such as copper. This ensures good heat transfer in the direction of the mold component in the forming space. Basically, the material of the cover should have a thermal conductivity ⁇ of ⁇ 10 W / Km.
  • Copper for example, has a thermal conductivity ⁇ of 394 W / Km.
  • the use of a cover made of iron is possible.
  • Iron has a thermal conductivity ⁇ of 73 W / Km.
  • the heating element is particularly intended to heat-insulate the heating element at all sides adjacent to the forming tool by an insulating layer, ie at the bottom and at the side walls.
  • an insulating layer ie at the bottom and at the side walls.
  • only a bottom-side insulation or insulation of the side walls may be provided.
  • FIGS. 1 to 4 components corresponding to one another each carry the same reference numerals.
  • FIG. 1 shows, in a perspective representation, a detail of a forming tool 1 of a device according to the invention, for example a press.
  • the forming tool 1 has an upper tool 2 and a lower tool 3, which are matched to one another in the contour. Between upper tool 2 and lower tool 3, a forming space 4 is formed.
  • a previously heated to a certain forming temperature sheet metal plate can be added and then pressed by Gegenrhythmverlagern of upper tool 2 and lower tool 3 shaping.
  • the mold component is cooled and cured.
  • a hard martensitic microstructure state is fundamentally set on the molded component.
  • the pressed-out mold component in the forming space 4 can be heated in certain regions.
  • a heating element 6 or 7 is integrated in a recess 5 of the forming tool 1.
  • FIG. 2 shows a heating element 6 with a circular cross-section, whereas the heating element 7, as shown in FIGS have square cross section with an edge length of for example 4 mm to 8 mm.
  • the length of the heating elements 6, 7 can be selected according to the particular requirements on the molded component.
  • the heating elements 6, 7 can be bent, so that even curved curved tool areas can be heated.
  • the heating element 6, 7 is separated from the adjacent walls 8, 9, 10 of the forming tool 1 and the lower tool 3 through an insulating layer 11, 12, 13 and thermally insulated.
  • an insulating layer 11 is provided below the heating element 6, 7 at the bottom 8 of the recess, Furthermore, an insulating layer 12 is also peripherally disposed between the heating element 6, 7 and the side walls 9, 10 of the recess 5.
  • the insulating layer 11, 12 is made of ceramic, a glass fiber mat or mica.
  • an insulating layer 11 made of ceramic or mica is integrated on the bottom 8 of the recess 5. Between the heating element 7 and the side walls 9, 10 of the recess 5 is provided as an insulating layer 13 each have an air gap for thermal insulation.
  • the heating element 6 On the upper side to the forming space, the heating element 6 according to the embodiment of Figure 2 by a cover 14 made of a material with good thermal conductivity, such as copper, completed.
  • the material of the cover has a thermal conductivity ⁇ which is greater than or equal to 10 W / Km.
  • the heating elements 6, 7, By means of the heating elements 6, 7, a controlled temperature control of the molded component in the forming space 4 can take place.
  • the isolation or thermal insulation of the heating elements 6, 7 according to the invention for the forming tool 1 prevents an adverse heat flow into the tool, so that the heating of the mold component is carried out effectively.
  • In the device according to the invention are also extremely different Abkühlgradienten within only a few millimeters on the mold component to realize.
  • the areas of the molded component heated in the forming tool 1 do not cool or barely cool when the press is closed. Only after the opening of the forming tool 1 is a cooling of the molded component with a low cooling rate in air. Due to this slow cooling rate, these previously heated areas have a softer material structure, so that cutting or punching operations can be carried out more simply and dimensionally true with less tool wear.
