Definitions

  • the invention relates to a forming press with a forming tool and a mold space between the lower part of the tool and Tool upper part for the production of workpieces metallic materials, especially aluminum, in the way media-assisted hot forming and in the Retractable forming dies with high pressure bores, which on a located in the mold space hollow blank, e.g. Pipe, according to the internal high pressure forming work, being under high pressure Forming liquid supports the forming.
  • the hot forming the blank can within the scope of the invention with the help a high temperature forming liquid. It but there is also the possibility of the blank and / or that Sufficiently heat the forming tool.
  • the invention has for its object a forming press to create the embodiment described above with which forms a shape on a tubular workpiece flawlessly without unwanted stretching of the Can produce workpiece wall.
  • the invention solves this problem with a generic one Forming press in that the upper part of the tool and / or Lower part of the tool for creating a shape on the resulting tubular workpiece one of the formation corresponding mold recess with one in the mold recess has counter-holder guided in the forming direction, of the molding speed and depth of the formed formation controlled.
  • These measures of Invention have the result that with the help of Forming direction as it were under braking and consequently Congestion caused by the counterhold, however, is sufficient do not drain too much material into the mold recess can, so there in the course of hot forming with A high pressure creates a formation in which a unwanted stretching of the workpiece wall is prevented.
  • a targeted material transport is particularly important achieved when the mold recess with the Counterholder orthogonal to the blank in the mold space flows and according to a proposal of the invention with independent Meaning the lower part of the tool or upper part of the tool on the opposite of the mold recess Side a slide guide with one in the molding space retractable slide that during production of the blank material in the direction of the molding suppressed.
  • the slide is over the Mold space center out into the mold space and against the High pressure applied to blank can be moved.
  • the invention provides that the slide after the Creation of the formation with internal high pressure Blank or emerging workpiece in its starting position moves back so that the depicts the tool shape formed thereby.
  • the invention provides that the Counterholder has a central stamp, which for Generation of two with a given distance from each other lying necklines against the direction of movement of the Bracket can be moved into the resulting shape and the middle part of the high pressure Forming in the direction of the center axis of the resulting Tool piece pushed back.
  • a handlebar for an axle beam like the one used in vehicle construction Use finds fasten.
  • Attachment of such handlebars to the axle component during hot forming creates a neck in which after a corresponding Elimination of neck parts of the handlebars articulated becomes.
  • a forming tool is from a forming press with a molding space 1 between the upper part 2 and lower tool part 3 for producing workpieces 4 made of metallic materials, especially aluminum or aluminum alloys, by means of an active media-supported Hot stamping shown.
  • This forming tool has forming dies that can be moved into the mold space 1 5 with high pressure holes 6, which in one in the Mold space 1 located hollow blank 7, according to the Embodiment a tube, according to the internal high pressure forming work. This is done under high-pressure forming standing forming liquid is pressed into the blank 7, which can itself be at a high temperature. But there is also the possibility of the blank 7 or the forming tool preheat to hot stamping under high pressure to be able to make.
  • the upper part 2 of the tool has a formation 8 one of the resulting tubular workpiece Forming 8 corresponding shape recess 9 with an in the mold recess 9 guided in the molding direction 10 on the the molding speed and Forming depth of the resulting formation 8 is checked.
  • the mold recess 9 opens with the counter holder 10 orthogonal to the blank 7 in the molding space 1.
  • FIGS. 1 to 3 has the lower tool part 3 on the mold recess 9 opposite side a slide guide 11 with a in the mold space 1 retractable slide 12 which during the creation of the formation 8 blank material in the direction the formation 8 presses.
  • the slider 12 is over the Center of the mold space into the mold space 1 and against blank 7 pressurized by internal pressure. After this Generating the formation 8, the slide 12 moves in internal high pressure blank 7 or largely created workpiece back to its starting position, see above that also in this area on the workpiece 4 depicts the tool shape formed. - Counterhold and Slide movements are indicated by arrows.
  • the Bracket 10 on a central punch 13, which for Generation of two adjacent to each other with a given distance Neckings 14, 14 'against the direction of movement of the counter holder 10 in the resulting formation 8 is movable and the middle part of the under Internal high-pressure formation 8 in the direction of Center axis of the resulting workpiece displaced.
  • the two neckings 14, 14 ' serve e.g. for fixing a handlebar 15 on a detail in FIG. 6 illustrated axle support 16.
  • the handlebar mounting between the neckings 14, 14 ' is without removal of necking material possible so that the whole Axle component 16 due to high rigidity and strength properties distinguished.
