Definitions

  • the invention relates to a stamp for a rotary press after the Preamble of claim 1.
  • Rotary presses are known to upper and lower punches, which in corresponding Piston guides of the rotor are guided axially and with die holes interact with the die plate.
  • the actuation of the stamp takes place with the help of stationary cams.
  • the pressing process, with the punches is performed, is effected by pressure rollers, against which the punches start and press the stamp down or up for the purpose of compression of the filled in the die holes powdery material.
  • stamp insert forms the actual Preßtechnikmaschine and thus determines the contour of the compact.
  • the invention has for its object to provide a stamp for rotary presses create, in which for a relative rotation opposite to the pressed tablet a separate drive can be dispensed with.
  • the approach of the punch insert between axially spaced Plugs guided helically in the bore and from a spring to Pretensioned front face of the punch holder At the beginning of a pressing process the punch insert moves into the punch holder up to a fixed one Attack. During this axial movement simultaneously finds a limited rotational movement the stamp insert instead. After pressing, the punch is raised, and the spring returns the punch insert to the home position. The punch insert performs a rotation and thus causes a release of the tablet.
  • One according to one embodiment of the invention is that rotatably connected to the free end of the neck a threaded spindle and in the bore a spindle nut is arranged rotationally fixed, with which the threaded spindle interacts.
  • the spindle nut can according to another embodiment be fixed by means of radial pins in the punch holder of the invention.
  • the Approach of the punch insert points to a further embodiment of the invention at least one radial pin, which engages in a groove of the punch holder, wherein the groove is dimensioned so that it the axial movement of the punch insert allows.
  • the pin can according to another embodiment of the invention, the end a radial pin, through which the spindle in a bore of the neck is fixed.
  • the angle of rotation is z. B. 10 to 30 °, preferably about 20 °.
  • the single FIGURE shows a section through a stamp according to the invention.
  • the punch has a punch shaft or punch holder 10 with a head 12, in a known manner with pressure rollers of the not shown Concentric press cooperates.
  • the punch holder 10 is not in holes shown punch guide axially guided and by a wedge 14 at a rotation prevented.
  • a punch insert 16 At the lower end of the punch holder 10 is a punch insert 16 to detect. It consists of an approximately cylindrical tool section 18, a pin-shaped cylindrical projection 20 and a threaded spindle 22.
  • An the head 12 opposite end of the punch holder is a stepped Bore shaped. In the first bore section with the largest diameter is the approach 20 slidably guided.
  • a spindle nut 24 is arranged, with the help of two opposite radial pins 26, 28 in the bore portion axially and set against rotation.
  • the threaded spindle 22 interacts with the nut 24 together.
  • a helical compression spring 30 is arranged, which rests on the bottom of the bore and on the spindle 22 acts and biases this away from the head 12.
  • the protruding sections are arranged in radial slots 34 and 36 of the punch holder 10, wherein the width the slots 34, 36 is significantly larger than the diameter of the pin 32nd
  • a sleeve 38 is attached, which is the Slits 34, 36 covers and partially over the tool portion 16th extends.
  • the latter has received in an annular groove an O-ring 40, the sealing cooperates with the inside of the sleeve 36. This prevents that Penetrate impurities.
  • the dimensions described are such that the pin 32 is not at the top the slots 34, 36 strikes; before it comes to the plant of the surfaces 42 and 44th together.
  • the pin 32 therefore only has to absorb the force of the spring 30 or the impact generated when the pin on the underside of the slots 34, 36 arrives at the plant.
