Definitions

  • the present invention relates to a powder press for producing a metal powder compact having an upper punch assembly, a lower punch assembly and a die assembly forming the mold cavity into which the metal powder is insertable and thereafter the upper punch assembly and the lower punch assembly for forming the compact Pressable against each other in the pressing direction, controlled by a control unit.
  • Such powder presses are known in many ways, they are used to produce powder compacts, which are then sintered, whereby a variety of workpieces can be produced, which can meet the most diverse requirements for these workpieces in the most optimal manner, for example, indexable inserts are made in this way, the very be exposed to high loads.
  • pressing is primarily in a pressing direction, which is usually vertical.
  • transverse mandrels are introduced through the Matrizenwandung transversely to the pressing direction in the mold cavity before the pressing process, which usually come to a punch of the lower punch assembly to the plant.
  • These transverse mandrels are moved via direct linear drives, for example hydraulically, which is possible because these transverse mandrels do not have to absorb any pressing forces in their direction of movement.
  • the object of the present invention is to design the powder press so that the compact can be deformed during the pressing process with Querpressstkovn.
  • the solution of this object is achieved in that the lower punch assembly is equipped with a plate on which the die assembly is mounted, and on which plate transverse pressing devices can be fastened, each with a Querpressstkov are equipped which is linearly driven by a drive and can be pressed through an opening in the die substantially transversely to the pressing direction in Querpressides into the mold cavity into a pressing position and retractable from this.
  • the drive of each transverse pressing device comprises a linear drive with a fixed part attached to the frame of the transverse pressing device and a part which can be displaced linearly relative to the fixed part, which linearly displaceable part is connected to a first wedge whose wedge surface acts on the wedge surface of a second wedge which is displaceable substantially perpendicular to the first wedge in the transverse pressing direction.
  • first wedge and the second wedge are displaceable along linear guideways attached to the frame of the transverse pressing device, whereby the occurring forces acting on the transverse ram are largely absorbed by the frame.
  • a further advantageous embodiment of the invention is that the pressing position of the cross press ram can be fixed by an adjustable stop, whereby the pressing position of the cross press ram is always reached very accurately regardless of further influences.
  • the stop is formed of a transverse to the direction of displacement of the first wedge adjustable third wedge, which is guided in the frame and whose wedge surface cooperates with a further wedge surface of the first wedge.
  • the position of the cross press ram with respect to the die assembly via measuring means can be detected and transmitted to the control unit, whereby the position of the transverse ram is monitored and the adjustment of the pressing position of the cross press ram over the stop is easily possible.
  • a further advantageous embodiment of the invention is that each cross-pressing punch is held via a coupling device in the respective transverse pressing device.
  • the transverse pressing dies can be exchanged in a simple manner, while the transverse pressing device can be used for virtually all compacts to be pressed having different shapes.
  • each transverse pressing device is equipped with a protruding bolt and that the plate is provided with a plurality of holes, which bolt protrudes in the mounted on the plate state of Querpressvorides in one of the holes, and that a plurality Querpressvoruzeen on the Plate can be fastened in different position.
  • the transverse pressing devices can be used in predetermined positions for specific die arrangements without having to carry out large orientations of the transverse pressing devices.
  • the holes in the plate corresponding threaded holes are assigned, in which clamping screws are screwed, which are held in corresponding recesses in the context of each transverse pressing device.
  • the transverse pressing devices in the corresponding positions on the plate can be fastened in a simple manner.
  • the recesses for receiving the clamping screws in the transverse pressing device are slot-shaped, so that the patch on the plate transverse pressing device each slightly pivoted about the bolt and thus can be aligned with respect to the die, after which the cross pressing device on the plate on the clamping screws can be fixed.
