Definitions

  • the invention relates to a press with the features specified in the preamble of claim 1.
  • a press for producing roof tiles is known from EP-B-0 434 863.
  • the known press has a six-surface drum mounted as a support for lower molds in the machine frame, the six lateral surfaces of which are mounting surfaces for the lower molds.
  • the lower forms work with an upper form together, which is provided on the underside of a press ram or bear, which is guided up and down in the machine frame.
  • vertical guide rails are provided on a right and a left stand of the machine frame, which guide the bear along eight guide surfaces.
  • the present invention has for its object to show a way how to guide the bear or pressure beam of a press at the ends, so that tilting moments about an axis that is perpendicular to the plane spanned by the machine frame and the direction of movement of the bear, also low overall height of the bear are easily controllable and inevitable wear on the guides occurs more evenly.
  • the body with the partially cylindrical outer surface can in principle be inserted loosely into the associated recess of the pressure beam, because it is held captive in the recess by the guide of the machine frame facing it and aligns itself automatically so that its end surface is parallel to the guide of the machine frame .
  • the body is preferably held in the recess by a recessed bolt which passes through the body with a certain axial and radial play, the play being dimensioned such that it can compensate for the tilting movements of the pressure beam which may occur.
  • a loose mounting of the body facilitates the assembly of the pressure beam in the machine frame.
  • the axial play of the bolt is preferably compensated for by a compression spring through which the bolt extends, the compression spring being intended to be arranged such that it presses the body into its recess.
  • the recess which receives the body serving as guide, in one to form a detachable component from the pressure beam and to utilize this separate design from the pressure beam in order to provide a sensitive adjustment option at the interface between the pressure beam and this separate component by means of an adjusting wedge, for which purpose two inclined surfaces complementary to one another are required, which have a small angle to the direction of movement of the bear and thus include to the longitudinal direction of the guides.
  • a separate wedge could be inserted between the pressure beam and the detachable separate component, which carries the body serving in the guide, but it is simpler and therefore preferred that the one inclined surface on the component itself and the opposite inclined surface at the end to provide the pressure beam, whereby the component itself becomes an adjustable wedge relative to the pressure beam.
  • the inclined surfaces expediently extend over a large part of the cross section of the pressure beam, so that they can easily transmit the lateral forces that occur.
  • the actual pressing forces do not have to transmit the inclined surfaces, since the forces driving the pressure beam act directly on the pressure beam.
  • Adjusting means provided for adjusting the detachable component formed with the inclined surface therefore do not have to absorb the compressive forces during pressing either, but can be trained relatively weak.
  • a screw is preferably provided which is screwed into the pressure beam and which at the same time is in engagement with the detachable component. Turning the screw changes the relative position between the pressure beam and the detachable component along the inclined surfaces. So that the set screw does not have to ensure the cohesion between the pressure beam and the detachable component at the same time, further screws connecting the component and the pressure beam are provided to secure the set position, with washers for compensating the adjustment path between the components and the pressure beam.
  • the invention is applicable not only to roof tile presses, but also to other presses which work with a press beam or bear in which the control of tilting moments which occur along the pressure beam and the wear caused thereby are a problem.
  • the invention is particularly suitable for presses in which the pressure bar is moved up and down on vertical stands, but could also be used in presses with a horizontally movable pressure bar.
  • the pressure bar of the press is also referred to as a bear in the following description.
  • the press has a machine frame 1 with a left-hand stand 2, a right-hand stand 3 and a horizontal traverse 4 connecting the two stands at their upper end.
  • a hexagonal drum 5 which has a horizontal axis of rotation, with pins stored in roller bearings 7, which are arranged in the two stands 2 and 3.
  • a particularly suitable way of storing the drum 5 is the subject of the patent application filed on the same day EP-A-0 740 601 with the title "Storage of a drum in a press for ceramic compositions, in particular for the production of roof tiles".
  • an electric motor 8 is provided on the machine frame 1, which acts in a manner known per se on a non-rotatably connected Maltese cross 9 connected to the drum 5.
  • the drum has 6 mounting surfaces 10, each of which is set up to accommodate three sub-molds 11. (The lower molds are only shown on the top mounting surface). Three upper molds 12 matching the lower molds are located on the underside of a bear 13 which is designed as a bar and is guided with its two ends in vertically extending guides 14 which are attached to the two stands 2 and 3.
  • the bear 13 is suspended from the crossbar 4 by means of two knee levers 15 and 16 arranged in mirror image.
  • the crossmember 4 has two bearing blocks 17 on its underside, to each of which a two-armed lever 18 is articulated. Opposite the bearing blocks 17 there are two further bearing blocks 21 on their upper side of the bear 13, to each of which a one-armed lever 19 is articulated.
  • the two levers 18 and 19 are each articulated to form a knee 20.
  • the lower end of the spindle 25 projects through a collapsible bellows 26 into a recess in the bear 13.
  • the relative position between the bear 13 and his two bearing blocks 21 can be adjusted by an adjusting device 27 in order to compensate for wear on the molds 11 and 12.
  • a particularly suitable adjustment device is the subject of the patent application filed on the same day with the title "Press for pressing ceramic masses, in particular for producing roof tiles".
  • the spindle 25 is extended upwards by a shaft 34 which extends through the cross member 4 and ends in a brake 28. On the shaft 34 sits a gear 35, which meshes with a toothed belt 29 and is further tensioned via a pinion 30, which is fastened on the output shaft 31 of an electric servo motor 32, which is attached in a hanging arrangement to the outside of the machine frame 1.
  • the servo motor 32 has partially broken away in FIG. 1 in order to make the planetary roller spindle gear visible.
  • the pinion 30 and the toothed belt 29 are covered by a housing 33.
  • Figures 1 and 2 show the bear 13 in its raised position, the lower mold 11 and the upper mold 12 are separated from each other.
  • the spindle nut 24 is moved downward by rotating the spindle 25, as a result of which the toggle levers 15 and 16 are stretched and the bear 13 moves downward.
  • the pressure beam or bear 13 has a relatively low overall height.
  • 13 special guide means are provided at the ends of the bear, which are shown in detail in FIGS. 3 and 4. These guide means are formed at both ends of the bear 13 in a corresponding manner, so that it is sufficient to show them at one end of the bear.
  • the bear has at its ends an inclined surface 61 which, with the vertical direction of movement of the bear, encloses a small angle which is only about 1 ° to 2 °.
  • a component 62 is detachably attached to this inclined surface 61, which has an inclined surface 63 that is complementary to the inclined surface 61. Because of the inclined surface 63, the component 62 has the function of a wedge tapering from top to bottom. As FIGS. 3 and 4 show, the component 62 has on its head 62a horizontal projections 64 which protrude beyond the end of the bear to the front and to the rear and by means of screws 65 which are rotated from above by the head 62a in the bear 13 , are attached to the bear.
  • screws 65 are screwed from above into the end section of the bear through compensation plates 66 which can be inserted from the side.
  • the head 62a has a horizontal, semicircular recess 67 into which a matching projection 68 with a semicircular end face engages.
  • the projection is part of a collar 69 which is rotatably mounted on the shaft of an adjusting screw 70, but is axially immovable.
  • the adjusting screw 70 is screwed into a bore of the bear 13 from above.
  • the adjusting screw 70 can be actuated, thereby lifting the component 62 or - After removing one or more compensating plates 66 - lower and thereby, via the interaction of the inclined surfaces 61 and 63, at the same time approach or remove a guide surface 71 provided on the outer end of the component 62 of the guide 60 on the machine frame 1.
  • the wedge-shaped component 62 can be fixed by tightening (countering) the screws 66.
  • the guide surface 71 moved with the bear is formed on a body 72, the surface 73 of which faces away from the guide 60 has the shape of a cylinder jacket section and lies in a matching recess 74 of the component 62, the guide surface 71 moved along over the band 75 of the recess 64 protrudes.
  • the moving guide surface 71 is the surface of a plate made of low-friction plastic, which is attached to the body 72, for example by gluing.
  • the body 72 and the component 62 are connected to one another by a screw bolt 76; In order to be able to arrange it sunk, a recess 77 is provided in the body 72 and a recess 78 in the component 62.
  • the bolt 76 connects the component 62 and the body 72 with radial and axial play in order to allow a limited rotation of the body 72 in the recess 74.
  • the axial play is compensated for by a spherical shim 79 between the head of the bolt 76 and a concave end surface of the recess 77, the center of curvature of the concave end surface being on the longitudinal axis of the cylindrical outer surface 73.
  • a plate spring is also provided between the washer 79 and the head of the screw bolt 76, so that the body 72 is pressed resiliently into its recess 74 when the screw bolt is tightened.
  • the bear 13 can yield to it within the limited rotatability of the body 72, without this affecting the parallelism between the plastic plate and the guide surface 87 and changes something in the uniform introduction of force from the plastic plate into the guide surface 87.
  • the plastic plate is typically 4 to 5 mm thick and can be replaced when it is worn out.
  • the guide surfaces 62 channels are provided in the component through which a lubricant can be supplied.
