Definitions

  • the invention relates to a powder press for producing a compact of a powdery material, in particular metal powder or ceramic powder.
  • Such a powder press includes a frame, an upper punch assembly, a lower punch assembly, and a die assembly disposed between the two punch assemblies.
  • the die assembly defines a mold cavity into which the powdered material can be filled. Thereafter, the upper punch assembly and the lower punch assembly can be pressed against each other to form the compact.
  • the invention has for its object to provide a powder press, in which the said disadvantages of known powder presses are largely avoided.
  • a powder press for producing a compact of a powdery material, with a frame, an upper punch assembly, a lower punch assembly and a arranged between the two punch assemblies die assembly which defines a mold cavity, in which the powdered material can be filled and thereafter for forming the compact, the upper punch assembly and the lower punch assembly are pressed against each other, according to the invention on the one hand the upper punch assembly has an upper spindle drive and on the other hand, the die assembly and / or the lower punch assembly has at least one lower spindle drive.
  • the inventive use of one or more spindle drives results in a short drive train ("direct drive"), whereby a high rigidity and thus high dynamics of the press drive is achieved even with large moving masses and / or large pressing forces.
  • the invention thus has, on the one hand, an upper direct drive for the upper punch arrangement and, on the other hand, at least one lower direct drive for the die arrangement and / or the lower punch arrangement.
  • a direct drive on the inventive powder press is preferably characterized in that the drive motor acts directly on the spindle and this in turn directly or via a plunger on the punch assembly or on the die assembly, ie that both between the drive motor and spindle and between the spindle and punch assembly or between the spindle and die assembly no belt, gear, eccentric, knee lever or the like. Is provided.
  • the spindle drives are controlled spindle drives.
  • the spindle drives in the pressing process e.g. take into account the properties of a particular powder material as well as the desired properties of a compact produced from the powder material. But also damage to the press can be avoided, which could be caused by incorrect operation or malfunction of the press.
  • the upper punch arrangement, the die arrangement and the lower punch arrangement have only spindle drives for their drive. This gives all the movable arrangements of the press a short drive train and thus a high rigidity, thereby a significant contribution is made to the accuracy of the inventive press.
  • the die assembly is movable and has a die drive.
  • a die drive This allows operation of the press according to the invention optionally in the withdrawal process, in which the die is withdrawn vertically from the compact after the pressing process, or in the ejection process, in which the compact is ejected against the die friction by means of the lower punch.
  • the die arrangement can also have a die spindle drive for this purpose.
  • the controlled punch or die spindle drive is preferably a servo motor arrangement, in particular with a rotation angle sensor for rotation angle control, a speed sensor for speed control or a torque sensor for torque control and with a position sensor for detecting a linear position of the respective punch or die. It is particularly advantageous if all drives are equipped by servo motors and their sensor or sensors for detecting one or more operating parameters, wherein preferably also the sensor or sensors associated memory means are provided for storing the operating data thus detected.
  • a spindle drive and preferably each of the spindle drives of the press, includes a servo motor assembly having a sensor for detecting a spindle position and a sensor for detecting a change in spindle position.
  • the sensor for detecting the spindle position is preferably a linear position sensor, e.g. an optical, an inductive or a resistive sensor.
  • the sensor for detecting a change in the spindle position is preferably an angular position sensor, such as e.g. an optical, an inductive or a resistive sensor.
  • a spindle drive and preferably each of the spindle drives includes a servomotor arrangement with a sensor for detecting a spindle torque. This allows a shutdown of the press, if on at least one of the spindle drives torque which exceeds a maximum permissible value. When the maximum torque is exceeded, an emergency stop can be initiated.
  • the current flowing through the spindle driving motor can also be used. As a result, it is not only possible to implement the initiation of an emergency stop, but it is also possible to carry out an idle stroke, ie, a rotation and axial movement of the spindle, with the spindle.
  • Such idle strokes may be performed from time to time after predetermined service intervals to determine the condition of the spindle, nut and bearings. If the measured idle stroke exceeds a maximum allowable idle stroke, it may serve to provide early detection of mechanical damage, allowing for preventative maintenance.
  • the servomotor for producing a controlled rotary drive is a hollow-shaft electric motor. Inside the hollow shaft is the rotating element of the spindle drive. This allows a compact design, in particular a low overall height, and a particularly short drive train in the inventive press.
  • a spindle drive and preferably each of the spindle drives includes a threaded rod-nut block unit with a threaded rod external thread and a complementary mother block internal thread.
  • a torque-free linear drive can be generated by way of the nut block, which engages with the rotationally driven threaded rod and which only makes a linear movement along the longitudinal axis of the threaded rod about its longitudinal axis when the threaded rod is rotated.
  • the threaded rod by means of the motor, in particular by means of a servomotor, rotatably driven, and the mother block is rigidly connected to the punch assembly or with a plunger or with it in one piece.
  • the upper punch assembly, the die assembly, or the lower punch assembly two or more parallel to each other identical spindle drives.
  • a plurality of parallel and parallel driving forces on a punch or die assembly performing spindle drives a given linear or axially acting driving force in such an arrangement (punch or die) not only torque-free, but also practically be introduced without bending. This too is an important contribution to increasing the accuracy of the inventive press, in particular in the production of compacts having large dimensions transverse to the axial pressing direction.
  • the powder press preferably contains a control unit or a control unit for controlling or controlling the movement of the spindle drives.
  • the control unit or control unit is designed in particular for the synchronized movement of the spindle drives and in particular for the mutual compensation of the individual angular momenta of the spindle drives.
  • the linear force and / or the Torque of the spindle can be used as a controlled variable.
  • the linear force and / or the Torque of the spindle can be used as a controlled variable.
  • the upper punch assembly has a single upper spindle drive, wherein the die assembly or the lower punch assembly has two lower spindle drives.
  • the design with two lower spindle drives on the die assembly enables the provision of a pull-out method powder press.
  • the design with two lower spindle drives on the lower punch assembly makes it possible to provide a powder press operating according to the ejection method.
  • the spindle drives include ball screws or satellite roller spindles (i.e., roller rotatable spindles) to minimize friction between the rotating threaded rod and the nut block, thus providing virtually torque free axial drive over the nut block.
  • the hollow shaft motor contains braced bearings.
  • cooling fins may be provided on the housing of the Hohiwellenmotors, wherein the hollow shaft motor is conveniently associated with a fan.
  • the described powder press according to the invention not only enables the high precision and high dynamics achieved due to its high rigidity, but is also characterized by a low maintenance requirement and a small number of energy transmission lines (no hydraulic hoses) and a small number of passive drive elements (no belts, gearboxes , Eccentric, knee lever and the like.).
