Definitions

  • the invention relates to a press for producing dimensionally stable compacts of powder material according to claim 1.
  • Presses for the production of dimensionally compact compacts of powder material basically have a die, at least one upper and at least one lower punch, which compress the powder material in the cavity of the die from opposite sides.
  • Upper and lower punches are connected, for example, with the plunger or the piston rod of a hydraulic cylinder, which are mounted on the press frame.
  • the powder material is introduced into the die bore with a suitable filling device, the position of the lower punch normally defining the filling level or the filling volume. After pressing the material, the compact is removed from the die bore.
  • the pressing tools are usually not attached directly to the adjusting drives, but via so-called.
  • Adapters For example, the die is mounted on a die holding plate, which - if movable - in turn is connected by means of force transmission elements with an adjustment. The same applies to upper and lower punches, which are attached to corresponding holding plates. As a result, different pressing tools can be installed in an existing press.
  • the pressing force is measured to determine the maximum force with which the powder is compressed.
  • the Preßkraftverlauf the tools over the way or over time during the pressing process is helpful.
  • Another parameter is the position of upper and lower punches with respect to a reference, which is usually formed by the upper edge of the die.
  • a reference which is usually formed by the upper edge of the die.
  • suitable measuring systems the position of the tools on their adapters can indeed be measured, without a correction over the respective temperature and pressing force, the position determinations are not sufficiently accurate enough.
  • Out DE 102 54 656 B4 a typical hydraulic press has become known in which a die holding plate and a plurality of stamp carriers (adapters) are mounted in the press frame so as to be adjustable via hydraulic drives.
  • the known press support devices are provided which support the punch carrier in press end position relative to the main body of the press frame.
  • Out DE 3142126 B1 is a press for the production of stepped dimensionally pure Pulverpreßlingen made of ceramic material known in the lower punch bearing receiving plates are all hydraulically movable from a base plate and sit in the press end position as receiving plates on adjustable mechanical stops of the base plate.
  • the receiving plates are for ejecting the compacts after removal of the die and free coming into contact with the die in contact surface of the compact together in each case until the coming of the next contact surface gradually ACfahrbar.
  • the counterforce or support force is formed by mechanical stops in both presses.
  • Out DE 103 00 722 B3 has become known a press in which an upper and a lower carriage for the attachment of an upper and lower punch on a guide column are guided vertically.
  • the guide column is attached to a frame table on which the die holding plate is mounted.
  • a wear-free guidance of the carriage takes place in that via an angle compensation element and a lateral compensation element is a connection of the carriage to the hydraulic drive.
  • the holding device for a mold for the production of plastic moldings.
  • the holding device consists of two lateral, spaced frame, the side frame holding beams.
  • the support beams in turn hold retaining bars for the plastic mold.
  • the holding distance can be changed.
  • the spacing of the beams can be adjusted. As a result, an adaptation to the dimensions of the respective plastic mold is achieved.
  • the invention has for its object to provide a press for producing dimensionally stable compacts of powder material, which can be easily adapted to the desired removal / removal of the compact from the die bore and also allows the lowest possible position determination of the tools.
  • a guide column is arranged outside a Hauptpreßachse with two parallel guideways on which all holding plates are guided on one side vertically. Adjusting the retaining plates on the guideways, which preferably run along guide rails, are such that the mounting of one web forms the reference side and that of the other forms the following page in order to provide the necessary precision.
  • the guide rails are according to an embodiment of the invention in cross section dovetailed.
  • the guide column is seated at the lower end fixed to a frame-fixed plate, with which preferably also the lower adjustment drive is connected, while the upper end is connected to the press frame, wherein it is fixed according to the invention only in the horizontal direction.
  • the press frame is known to absorb the pressing forces and thereby suffers a more or less pronounced deformation. However, this does not affect the guide column, if it is set only horizontally at the top, while in the vertical direction, a relative movement between the guide column and press frame is possible to keep thermal or Preßkraftverformitch the frame of the guide column.
  • the compact can be removed in the ejection or withdrawal without the support plates must be replaced. It depends on the mode of operation of the press, which of the holding plates is brought into connection with the lower or the upper adjusting drive or which is to be fixed. Fixed stops are not required because the counterforce from the associated adjustment drive, e.g. Hydraulic cylinder can be applied. If, for example, the die holding plate can be moved during the withdrawal process, a feedthrough in the holding plate for the lower punch must be provided, so that force transfer elements can be connected by the adjusting drive to the die holding plate. When converting from the discharge operation to the withdrawal operation, therefore, the installation of such power transmission elements is required. The effort for this is relatively low. If two or more holding plates are provided for a plurality of lower punches, it is understood that at least up to the upper all holding plates must have openings for the passage of force transmission elements to the respective overlying holding plate.
  • the adjustment axes of the upper and lower adjustment are precisely aligned with each other.
  • the upper adjustment sits positively in an upper bearing plate, which in turn is bolted to an upper connection plate of the press frame.
  • An alignment plate is connected to the upper end of the guide column, and the bearing plate and alignment plate can be fixed to each other horizontally by a positive connection.
  • the lower adjustment is positively arranged in a lower bearing plate, wherein the guide column is supported on the lower bearing plate.
  • the bearing plate and alignment plate have at least a few aligned bores for receiving a dowel pin.
  • two pairs of holes and two dowel pins are provided. These ensure that the upper bearing plate are adjusted with the upper adjusting drive before the upper bearing plate is fixed to the connecting plate and thus the press frame.
  • the coupling takes place in the upper region, therefore, exclusively in the horizontal plane, while in the vertical direction, a relative movement between the press frame on the one hand and guide column on the other hand remains possible to - as mentioned -preßkraft- and temperature-induced strains of the press frame not to transfer to the guide and the holding plates.
  • support columns of a press frame are arranged in a rectangle or square.
  • an embodiment of the invention provides that the guide column is arranged in a corner region of the rectangle or square on the inside of the associated frame column. This increases the flexibility in terms of horizontal transverse movements in die height and the accessibility of the die. Breakthroughs in the frame for the filling axis or for other transverse axes are therefore not necessary.
  • an embodiment provides that a single measuring ruler is attached to the guide column, wherein the number of cooperating with the measuring ruler measuring carriage corresponds to the number of holding plates.
  • the measuring ruler is fastened according to a further embodiment only in a reference plane of the pressing tools, which is preferably formed by the clamping plane of the die or Matrizenoberkante.
  • the thermal fixed point is located in the middle of the length measuring systems. This leads to a change of direction of the longitudinal extent when the measuring slide passes through this fixed point. Since the linear expansion is additionally affected by the attachment to which the length measuring systems are mounted, the influence of temperature and Preßverformungen on the measurement results is minimized in the invention.
  • the arrangement of the guide column a freely accessible press room is created. With the help of the press according to the invention, both the ejection and the discharge process can be realized.
  • the die level or the decrease height can be changed within limits.
  • the individual holding plates have identical behavior mutually on by the same deformations due to the same storage. Vertical forces on the guide column do not occur.
  • the storage of the holding plates is decoupled from the press frame, whereby deformations of the press frame by pressing forces and / or temperature does not directly affect the storage of the holding plates.
  • a bearing plate 10 can be seen, on which a guide column 12 is supported by a substantially rectangular or square cross-section.
  • the guide column 12 is preferably formed in one piece and may also be integrally formed with the bearing plate 10.
  • two parallel guide rails 14, 16 are mounted, preferably by means of screw, which are dovetailed in cross-section.
  • the vertical parallel guide rails 14, 16 support guide carriages 18, 20, 22, 24, 26, 28 and 30, 32, which are mounted on horizontal, axially spaced retaining plates 34 to 40.
  • the holding plates are constructed substantially the same and have T-shape in section.
  • the upper holding plate 34 is used for clamping a top punch (not shown)
  • the holding plate 36 is a die holding plate and is used for clamping a die
  • the lower holding plates 38, 40 are used for clamping Unterstkovn.
  • the holding plates 34 to 40 can with a in FIG. 1 not shown upper and lower hydraulic drive are coupled for the purpose of vertical adjustment along the guide rails 14, 16. This will be discussed below.
  • the lower holding plates 38, 40 have openings 42, 44 for the passage of power transmission elements of a lower hydraulic drive to the respective overlying holding plate, ie in the present case the die holding plate 36 and the holding plate 38th
  • a horizontal alignment plate 46 is fixed, which has two holes 48 near the free end.
  • a measuring ruler 47 is mounted, slide on the Meßschlitten 48, 50, 52, 54.
  • the measuring slides 48 to 54 are each coupled to a holding plate 34 to 40 or in operative connection. With the help of the measuring slide 48 to 54 and the ruler 47, the position of the Holding plates 34 to 40 determined and thus the position of the dies, not shown.

  • An upper bearing plate 72 positively receives an upper hydraulic drive 74.
  • the bearing plate 72 can be screwed into a recess of the upper connecting plate 58.
  • the bearing plate 72 has two bores, one of which is shown at 76. They are aligned to the holes 48 of the alignment plate 46.
  • dowel pins can be inserted, of which one at 78 in FIG. 2 is shown. This makes it possible to position the bearing plate 72 horizontally with respect to the alignment plate 46 and thereby also bring the axis of the upper hydraulic drive 74 in alignment with the axis of the lower hydraulic drive 68, whereby a common vertical axis 72a is achieved. In the vertical direction can be allowed between the guide column 12 and the frame, here represented by the columns 56 and the connecting plates 60, 58, a relative movement.

  • FIGS. 5 and 6 is the unit after FIG. 1 also shown substantially in perspective. Therefore have parts in the FIGS. 5 and 6 the same reference numerals, as far as they are with those of FIG. 1 to match.
  • the bearing plate 10 is omitted and instead the upper end of the lower hydraulic drive indicated at 92. They are also in accordance with FIG. 4 the power transmission elements for the holding plates 36 to 40 indicated. In FIG. 6 Incidentally, the pair of power transmission members 88, 90 omitted for the lower holding plate 40.
  • Support columns 94, 96 are also shown, which at the bottom in a manner not shown in detail in the press frame or on the bearing plate 10 are rotatably mounted about a vertical axis. They have at the upper end of support portions 98, 100, which are formed so that in the one rotational position according to FIG. 5 the die holding plate 36 is supported and thus lies down against a fixed stop, while in the embodiment of Figure 6, the die holding plate 36 is free to move.

Upper and lower punches 104, 106 cooperate with the die 102.
  • the pressing tools are in the FIGS. 7 and 8 shown in a referencing position, wherein the upper edge of the die 103 is relevant for the referencing. Referencing sets the tool zero point of the system. Other tool parts refer to this zero point.
  • the thermal reference plane is the clamping plane of the die 102, ie the upper side of the die holding plate 36, with which the measuring slide 50 cooperates. In this plane, the measuring ruler 47 is fixed to the column 12 at 108, and only in this plane.
  • the measurement of the tool positions is not immediately possible, but - as mentioned - on the holding plates 34 to 38. Therefore, the temperature that is measured during referencing, must be included. A temperature measurement takes place at the points marked "T", ie at the holding plates 34 to 38, Upper punch 104 and lower punch 106 as well as in the die 102. When measuring the positions over the tool lengths 1 during operation, therefore, the value of the measured temperatures determined during referencing must be drawn in. In addition, in pressing forces occur length changes, which are measured by means of load cells, sensors or the like. These values must also be taken into account for correcting the respective tool positions.
  • a computer is required in which the signal values measured by the measuring ruler 47 as well as the temperature and force values are input in order to calculate the respective actual lengths 1 for determining the position.
