Definitions

  • the invention relates to a drawing tool for forming workpieces in a press, in particular for forming sheets into a molded part, with a punch and a workpiece carrier associated with the workpiece, wherein the workpiece carrier supported on a tool part and for forming the workpiece relative to this movable is, and with a Matritze.
  • Drawing tools of the aforementioned type are well known and are used, for example, to produce molded parts made of sheet metal, the u. a. find use for vehicle bodies.
  • Such sheet metal parts have a wide variety of geometries that are to produce with appropriate drawing tools in a press. Press-side secondary influences can negatively influence such a mold production process.
  • the drawing tool is characterized in that a force-adapted workpiece holder is provided on the workpiece carrier, which is designed to be movable via power adapter relative to the workpiece carrier.
  • a force-adapted workpiece holder which is formed for example as a sheet holder, is associated with the workpiece carrier or sheet metal forming the usual workpiece carrier.
  • the workpiece holder is to be moved together with the workpiece carrier by the workpiece holder is supported via power adapter on the workpiece carrier.
  • the workpiece holder is to be moved relative to the workpiece carrier.
  • the drawing path (Werk Glaismehub) is still taken over by the press.
  • the active force adapters have a shorter stroke than the stroke of the workpiece carrier, but these determine the effective pressing force acting on the workpiece, such as the sheet metal, as they rest on the workpiece and can perform compensating movements.
  • the power adapter and thus the workpiece holder fine movements during the forming process and thus perform during the production process.
  • the actual main movement is still performed by the workpiece carrier. Due to the fine movements, however, side effects in the production process can be avoided.
  • 1 is a drawing tool for forming workpieces 2 such as sheets generally numbered.
  • a workpiece carrier 3 is supported on a tool part 4 up and down movable about not shown in detail intermediate bolt.
  • a drawing punch 5 is provided and an up and down movable die 6.
  • the workpiece carrier 3 is also to move up and down.
  • spacers 7 are provided on the workpiece carrier 3
  • a workpiece holder 8 is provided within the cross-sectionally U-shaped workpiece carrier 3, which rests on power adapters 9.
  • the power adapter 9 also have up and down movable jib, wherein the stroke of the power adapter 9 is less than the stroke, which can pass through the workpiece carrier 3 during a production process.
  • Fig. 1 shows the state of the drawing tool 1 at the beginning of a molding process.
  • the sheet as a workpiece 2 rests on the workpiece holder 8 and is still undeformed.
  • Fig. 3 a relative movement to build up power and to compensate for disturbances between the workpiece holder 8 and the workpiece 3, triggered by the power adapter 9.
  • the corresponding movement arrows (movement; relative movement) and the corresponding force arrows (residual force, labor, total force) are shown in the figures.
  • Fig. 4 shows the parts of the drawing tool 1 during a drawing or forming process.
  • the workpiece carrier 3 together with the workpiece holder 8 can be moved while the die 6 moves downwards. The deformation is initiated.
  • Fig. 5 finally shows the state of the parts of the drawing tool 1 at the end of a forming process or drawing process.
  • the die 6 is still on the formed sheet 2.
  • Fig. 6 shows an alternative embodiment in which the tool part 4 is formed by the press.
  • the die 6 is in the lower region of the drawing tool 1. Accordingly, the tool holder 3, the workpiece holder 8 and the power adapter 9 are arranged above the die 6. The spacers 7 are located below the workpiece carrier 3 on the die 6.
