Definitions

  • the subject matter of the patent is a cutting die damper used to improve the adherence of the die cut material to the stripping board in the process of stripping the edges of the die cut material.
  • the cutting die damper as per the patent consists of two elements which slide in one axis and a spring aligning the position of the two elements against each other.
  • the internal damper sleeve has a mushroom-shaped element and is placed in a pass-through body provided with a flat bar fixing the body to the cutting die base.
  • the flat bar fixing the body supports a spring that at the other end rests against the mushroom-shaped element of the internal sleeve. This spring is located outside the working elements.
  • At the top part of the mushroom-shaped element there is a permanently fixed threaded insert into which there is driven the screw which fixes the mushroom-shaped element to the plate reflecting the shape of the die cut material.
  • the damper's body has on the internal side of the pass-through aperture a formed ring the diameter of which is not smaller than the diameter of the sleeve.
  • the ring supports a screw-mounted disk which fixes the sleeve in the damper's body.
  • the body is connected with the cutting die base using the fixing flat bar.
  • Illustration No. 1 shows the damper mounted in the cutting die, while illustration No. 2 - cross section of the damper.
  • the cutting die damper as per the patent and designed for use at the die cut material edge stripping board consists of two elements which slide in one axis and a spring which is located outside the elements.
  • the spring aligns the position of the two elements against each other.
  • internal damper sleeve (1) has a mushroom-shaped element (2) and is placed in a pass-through body (3) provided with a flat bar (4) fixing the body to stripping board (10) of the cutting die.
  • the flat bar (4) fixing the body supports an external spring (5) that at the other end rests against the mushroom-shaped element (2) of the internal sleeve (1).
  • the damper's body (3) has on the internal side of the pass-through aperture a formed ring (7) the diameter of which is not smaller than the diameter of the sleeve (1).
  • the ring supports a screw-mounted disk (8) which fixes the sleeves in the damper's body (3).
  • the body (3) is connected with the stripping board (10) of the cutting die using the fixing flat bar (4).
  • the design of the cutting die damper as per the patent allows fixing a number of dampers in the stripping board of the cutting die and, after the cycle of die cutting and/or die cut material edge stripping, lifts the plate with this material to the conveyor.
