Definitions

  • the invention relates to a method for producing a component from magnesium sheet by forming a semifinished product from magnesium sheet, in particular a semifinished product in the form of a magnesium sheet, in which the semi-finished product before forming to an elevated temperature, preferably heated to a temperature of at least 200 ° C and in a forming tool having a punch and a die is formed, wherein for forming the heated semi-finished product, a forming tool is used without internal heat source, and wherein the heated semi-finished product is placed without direct contact with the punch and the die in the forming tool. Furthermore, the invention relates to a system for producing a component from magnesium sheet.
  • magnesium sheets Due to the hexagonal lattice structure of magnesium, magnesium sheets are difficult to reform at room temperature. In particular, components made of magnesium sheet, which should have a complex three-dimensional shape, must be hot-formed to avoid cracks.
  • magnesium plates are shaped in the heated state using tempered tools.
  • various embodiments of tempered tools for forming magnesium sheets are known. For example, from the Korean patent application 10 2006 00 57 901 A a press for hot forming of magnesium sheet is known, which is equipped with an electrical resistance heater is. The resistance heating device is integrated in an upper tool part (die) and in an associated blank holder.
  • Tempered forming tools require in comparison to conventional tools used in cold forming a higher technical complexity and thus higher investment and higher operating costs. This negatively affects the cost of magnesium components.
  • This device consists of a heating unit in which heat-conducting plates are arranged above and below a metal workpiece. Once the metal workpiece has been passed over transfer devices between the heating plates, the heating plates are pressed onto the metal workpiece to heat it. After heating, the metal workpiece is transferred to a forming machine and formed there.
  • the present invention has for its object to provide a method and a system for producing a three-dimensional component of magnesium sheet, which allow low component costs.
  • the method according to the invention is characterized in that the semifinished product holder is designed as an active sheet metal holder and is positioned above the die associated with the die, and that the heated semifinished product placed on the semifinished product holder is subsequently provided with a Forming speed in the range of 15 mm / s to 500 mm / s is formed.
  • the system according to the invention is accordingly characterized in that the semifinished product holder is designed as an active sheet metal holder which can be positioned above the stamp and on which the heated semifinished product can be placed without direct contact with the stamp and the die in the forming tool, and that the forming tool has a drive . which causes a closing speed of punch and die in the range of 15 mm / s to 500 mm / s.
  • the present invention eliminates the additional expense caused by the temperature of the forming tool by means of an internal heat source.
  • the invention provides for the processing of a heated magnesium semi-finished product in a forming tool without an internal heat source.
  • the tool and operating costs and thus ultimately the component costs can be significantly reduced.
  • in the manufacture of components in relatively small quantities can be achieved by reducing the cost of tools a significant contribution to the efficiency of the component.
  • a three-dimensionally shaped component can be made from a for example heated to 250 ° C magnesium plate in a non-tempered forming tool without cracking, if too high temperature losses are avoided before the actual forming process by a direct deposition of the heated board is prevented on the punch or the die during placement (insertion) of the board in the forming tool, and the subsequent forming takes place at a relatively high forming speed (15 500 mm / s).
  • the average cooling rate for a 2.00 mm thick magnesium sheet, which is heated to a temperature in the range of 200 ° C to 250 ° C, is for example in air at room temperature of 20 ° C between 2 and 12 K / s.
  • This relatively low temperature loss can be ensured in a suitable transfer system that the heated Semifinished product or the heated board has a sufficiently high starting temperature before forming to allow a defect-free, in particular crack-free component at given degrees of deformation.
  • the inventive use of a non-tempered tool for forming heated magnesium plates also has positive effects in terms of dimensional accuracy and the handling of the components thus produced. Because of the significantly reduced temperature that the component has when it is removed from the non-tempered forming tool, the component is dimensionally stable compared to a manufactured in a tempered tool component and thus less prone to unwanted deformations during its removal from the forming tool and the subsequent Handling, which has a favorable effect on the dimensional accuracy of the component. Furthermore, the components produced according to the invention can be handled more easily due to their significantly reduced temperature, which they have when they are removed from the non-tempered forming tool. Here, conventional transfer systems can be used which are not temperature-stable or have a comparatively low temperature stability.
  • an advantageous embodiment of the method according to the invention provides that a forming tool is used as the forming tool, whose punch and / or die have an active cooling device.
  • the removal temperature of the component can be reduced faster, the dimensional accuracy of the component further improved and the handling of the component can be further simplified.
  • This active Cooling of the stamp and / or the die is particularly advantageous when relatively high numbers of pieces are to be formed in a given time, that is, when the desired Umform essence should be relatively high.
  • a heating of the forming tool due to the heated semi-finished product during production can be tolerated, if this does not have a negative impact on the dimensional accuracy of the finished component.
  • the heated magnesium sheet semifinished product is not stored directly on the stamp or the die, but the heated semi-finished product is placed on a forming tool associated Halbzeughalter, so that the essential surface area of the heated semi-finished before the actual forming process between the punch and die and spaced from these cantilevered is arranged in the ambient atmosphere.
  • the ambient atmosphere preferably ambient air, acts as a heat insulator. This ensures that the heated semi-finished undergoes only a very small cooling before the actual forming process.
  • the semifinished product holder is designed as an active sheet metal holder which is positioned above a punch associated with the die.
  • a further advantageous embodiment of the method according to the invention is characterized in that a semifinished product holder is used as a semifinished product holder whose surface region touching the heated semifinished product has a surface structure which has porous or recesses.
  • a further advantageous embodiment of the method according to the invention provides that a semifinished product holder is used as a semifinished product holder whose surface area touching the heated semifinished product is formed from a material or has a coating which has a thermal conductivity of not more than 20 W / mK at 30 ° C to 100 ° C ambient temperature. This also makes it possible to reduce the heat or temperature loss caused by heat conduction from the heated semifinished product to the semifinished product holder.
  • a further advantageous embodiment of the method according to the invention is characterized in that a die is used as the die, in the forming surface, which faces the hot semi-finished product, recesses are formed which cause a reduction of the contact surface facing the heated semi-finished product.
  • the depressions or the air contained therein acts heat-insulating, so that can be reduced in this way the heat or temperature loss of the heated semi-finished product.
  • a further advantageous embodiment of the method according to the invention provides that the semifinished product is transported directly into the forming tool by means of a transfer device equipped with a conductive heat source.
  • the semifinished product to be formed can be given a sufficiently high starting temperature before shaping, and at the same time the temperature loss of the semifinished product can be minimized prior to forming.
  • a further advantageous embodiment of the method according to the invention is accordingly characterized in that the semifinished product is simultaneously trimmed during forming with at least one cutting element integrated in the forming tool.

  • Fig. 1 can be seen that the placed in the forming tool board 2 is initially stored on the semi-finished 3.3 and is arranged both with respect to the stamp 3.1 and with respect to the die 3.2 at a distance. As a result, too fast cooling of the heated magnesium plate 2 is prevented.
  • the tool 3 is closed in order to transform the heated semifinished product into a shape predetermined by the stamp 3.1 and the die 3.2.
  • the deformation takes place with a relatively high deformation rate, so that the temperature loss of the heated workpiece (semifinished product) 2 during the forming is also kept low.
  • the forming tool 3 has a drive (not shown) which effects a closing speed of punch 3.1 and die 3.2 in the range of 15 mm / s to 500 mm / s.
