Definitions

  • the invention relates to a drawing device for presses with a mechanically driven ram and with a sheet metal holder, the holding force acting on the sheet metal, counteracting the drawing direction, is exerted via a pressure plate by means of a drawing cushion piston which supports it and is pressurized with pressure medium in a fixed drawing cushion cylinder.
  • the drawing cushion piston 10 is guided in a drawing cushion cylinder 12 fixed to the frame, in the lower region of which an annular piston 13 surrounding the piston rod 8 is also guided, the movements of which in the drawing direction downward through the end wall of the drawing cushion cylinder 12 and upward through an inner annular collar 14 on the drawing cushion cylinder 12 are limited.
  • a working cycle of the pulling device begins in the - shown in the drawing - initial position, in which a plate 27 rests on the plate holder 5, which is in its highest position, in which it rests against a collar 28 of the lower tool 3 from below.
  • the Ziehstössel24 begins its downward movement.
  • the control acts on the active surface on the top of the piston 9 with pressure medium, so that the piston rod 8 with all the parts attached to it and the sheet holder 5 are accelerated in the drawing direction.
  • the sheet metal holder 5 with the sheet metal 27 lying thereon drops so far that the upper sides of the sheet metal holder 5 and the lower tool 3 are at the same height and the sheet metal 27 rests on the drawing die 4.
