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.
  • a stone press is known from DE-Al-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 presses 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. Depending on the application, other similar systems require the installation of additional fixed or movable stamps.
  • the three or more tool elements mentioned are then moved against one another for pressing the filled raw materials. At least two tool elements move in relation to the press mold.
  • the upper punch presses from top to bottom, and the frame of the press mold can also be moved in the pressing direction.
  • the lower punch on the other hand, is firmly attached to the lower crossbeam of the press frame and remains stationary.
  • 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 for presses for large parts are correspondingly heavy, so that mechanical aids for moving in and out are required when changing the mold.
  • the mold changes in particular those of heavier weights of one or more tons, are carried out using the mechanical aids mentioned, e.g. with forklift trucks or hoists by moving them to a ready-made mold changing trolley.
  • Such methods involve a disadvantageous effort due to the relatively expensive hoists.
  • 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 being effected by 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 operation of the vertical press in which a displaceable unit for receiving the mold carrier element for the mold is vertically displaceable between the top and a bottom mold carrier element and the mold carrier element has devices for coupling interchangeable parts, is characterized in that the interchangeable parts Parts are moved into a suitable position for coupling to the lifting means with the aid of the vertically displaceable unit and by distance-retaining coupling elements, coupled to one another and coupled to this lifting means as a package, the lifting means themselves not being displaced vertically.
  • the advantage achieved by the invention is that the handling of the press is considerably simplified and existing press controls can be used without problems for controlling the lifting means and for changing parts.
  • FIG. 1 shows a perspective view of a press device according to the invention, for example.
  • Figure 2 is a schematic view of a press device according to the invention, which has a filling box.
  • the press device illustrated essentially comprises a hydraulic one actuated four-column press 1.
  • a mold carrier element 4 which is also guided on the columns 2, is mounted.
  • 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 also 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 sliding assembly 5 is raised and 'is lowered by two "piston rods 9, of which only one is visible, the mold support member 8, however, 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.
  • a guide rail 10, 10 'in the form of a hollow profile is attached to the uppermost mold carrier element 4 on two opposite sides.
  • 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 ⁇ I1 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 stamps 6, 6 ', the two lower stamps 7, 7' and the mold carrier element 5 ', which are coupled to one another by distance-maintaining 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 mold carrier elements 6, 6 ', 7, 7', 5 'via 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.
  • a piston 6 projecting downward is fixed in a stationary manner.
  • a pressing plate 18 which can be moved along the columns and in the middle of which a piston 7 projects upwards.
  • a unit 5 which can also be moved along the columns 2 and on which a molding frame 24 is fastened.
  • the molding frame 24 has a hollow shape 26. The bottom of the hollow mold 26 is formed by the piston 7.
  • a support 28 which is arranged on the displaceable unit 5 and carries a hydraulic device 30 for displacing a material container 32 which is open at the top and bottom.
  • the material container 32 is guided by guide rods 34.
  • a filling funnel 36 is provided on the support 28 for filling the material container 32.
  • the mold frame 24 can be aligned against the support 28 in such a way that they together form a table on which the material container 32 can be displaced from the filling funnel 36 to the hollow mold 26.
