Definitions

  • the invention relates to a vertical press with at least three mold carrier elements, of which at least two are vertically displaceable and one is arranged in a fixed manner, and to a method for using the vertical press.
  • a stone press is known from DE-A1-28 41 684 (Bucher-Guyer AG), in which the press stamps have exchangeable stamp plates.
  • the production of molded parts in the pressing process on such seizures of vertical design requires the installation and removal of corresponding interchangeable molds on at least three mold carrier elements.
  • At least one stamp is attached to an upper or lower stamp carrier, while a press matrix is installed in a mold carrier plate.
  • a change of the mentioned forms requires the exchange of all form elements. These remain installed in their frames or are connected to each other before expansion by connecting elements for joint expansion.
  • the molds are correspondingly heavy when feeding on large parts, so that mechanical aids for moving in and out are required when changing the mold.
  • the invention has for its object to avoid the disadvantages mentioned and at the same time other parts of presses, such as mechanical mixers installed in the area of the filling box, for the purpose of cleaning, maintenance or repairs in a simple manner to be replaced and made accessible.
  • this is achieved in a vertical press of the type mentioned at the outset by lifting means for exchangeable parts of the press, which are attached to the uppermost mold carrier element and are at least partially displaceable in the horizontal and / or vertical direction.
  • An essential feature of the invention is that the uppermost mold carrier element, to which the lifting means are attached, is vertically displaceable, the vertical displacement of the lifting means taking place by means of this displacement.
  • the lifting means viewed from a front side of the press, can be displaced horizontally forwards and / or backwards to outside the area of the press.
  • the lifting means are expediently attached to the uppermost mold carrier element outside the area which bears the mold.
  • the lifting means preferably comprise two running rails which are attached to two opposite sides of the uppermost mold carrier element, furthermore two running elements mounted at a fixed distance on each running rail, and on each running element an elongated lifting element which can be pivoted parallel to the running rail.
  • a programmed control for the movable mold carrier elements and lifting means is provided, which the Controls vertical movements step-by-step and shape-specific positions assigned to different shapes.
  • a method for an advantageous use of the vertical press for exchanging form elements of the press such as upper punch, lower punch and mold carrier element, or of other parts of the press, such as filling box, filling box mixer or the like, in which press a displaceable unit for receiving of the mold carrier element for the mold between the top and a bottom mold carrier element is vertically displaceable and the mold carrier element has devices for coupling interchangeable parts, characterized in that a) the interchangeable parts with the aid of the vertically displaceable unit and by spacing coupling elements in a suitable position for Coupling driven to the lifting means, coupled together and coupled to this lifting means as a package, whereby the lifting means themselves are not moved vertically, or that the interchangeable parts using the vertically displaceable unit or the lifting means in a gee ignete position for coupling to the mold carrier element and coupled by means of separate spacing coupling elements and that b) the interchangeable parts are combined as a package in or out of the press chamber.
  • the advantage achieved by the invention is that the handling of the press is considerably simplified and existing feed controls can be used without problems for controlling the lifting means and for changing parts.
  • the illustrated feeding device essentially comprises a hydraulic device actuated four-column press 1.
  • a hydraulic device actuated four-column press 1.
  • the mold carrier element 4 has a hydraulic drive 4 'arranged within the yoke 3 for lowering and a further hydraulic drive 4''for lifting.
  • a unit 5 located at the lower end of the columns 2 and likewise displaceable along the columns 2, which unit can accommodate a further mold carrier element 5 ′ which can be displaced together with the unit 5.
  • the mold carrier element 5 ' is shown in a position outside the unit 5 and is designed as a hollow shape, in which two upper punches 6, 6' and two lower punches 7, 7 'engage.
  • the upper punches 6, 6 ' are fastened to the mold carrier element 4 and the lower punches are fastened to a mold carrier element 8 and, together with the mold carrier element 5', enclose the product to be pressed.
  • the displaceable unit 5 is raised and lowered by two piston rods 9, only one of which is visible, while the mold carrier element 8 is not displaceable.
  • the hollow shape of the mold carrier element 5 ' is filled with press material by a filler slide, not shown, which pushes the press material over the hollow form of the mold carrier element 5' from outside the columns 2 via a support (also not shown).
  • the pressing material can, for example, be ceramic sand that is to be processed into refractory stones.
  • the operation of the press corresponds essentially to that of conventional presses, as described for example in DE-A-27 41 800.
  • a running rail 10, 10 'in the form of a hollow profile is attached to two opposite sides. These rails 10, 10 'protrude forward from the area of the four-column press 1 and each carry two running elements, to each of which an elongated lifting element 11 is attached.
  • the distance of the running elements in each running rail 10 or 10 ' is kept constant by spacing elements, not shown, and the lifting elements 11 are pivotally attached to the running elements with hinges in the direction parallel to the running rails 10 or 10'.
  • the running elements have drive elements, not shown, for displacement in the running rails.
  • a package is suspended from the lifting elements 11, which consists of the two upper punches 6, 6 ', the two lower punches 7, 7' and the mold carrier element 5 ', which are coupled to one another by distance-retaining coupling elements 13.
  • the components of this package are specific to the shape of the product to be pressed and, as shown, are moved out of the four-column press 1 for changing this shape by the lifting and transport means described above and placed on a shape changing carriage 12.
  • the hydraulic drive 4 'and an associated drive control of the uppermost mold carrier element 4 are expediently made usable for the vertical movement of the package mentioned, and also of its individual parts. In particular, this vertical movement also serves to couple the interchangeable parts 6, 6 ', 7, 7', 5 'over the distance-retaining coupling elements 13 even before the package is moved horizontally.
  • FIG. 2 shows a second embodiment of a hydraulic four-column stone press according to the Invention shown, wherein reference numerals, which also appear in Figure 1, designate corresponding components.
  • a yoke 3 is arranged, which is secured by column nuts 14 before moving out of the columns 2 during the pressing process.
