Definitions

  • the invention relates to a paving and brick splitting device.
  • a paving and masonry splitting device is known with an oscillatingly driven upper tool in a frame, which interacts with a lower tool, the upper and lower tools each comprising a plurality of individual splitting wedges which can be moved relative to one another in the splitting direction are hydraulically supported.
  • the upper tool is fed hydraulically.
  • the known device has an extremely complicated positioning device for the rock to be split between the upper and lower splitting wedges.
  • the positioning device comprises stationary fingers, vertically and horizontally movable fingers and lateral centering devices. The positioning fingers are used to lift the incoming rock slightly and to carry it between the lower and upper riving knife. Such a measure is also necessary in the known device since a work table serving as an abutment is missing. For this reason, the lateral centering device is also required.
  • EP-A-0 065 276 proposes a work table with a slot-shaped opening for the passage of the lower tool in the splitting device, which can be moved flexibly in the splitting direction, the work table being supported hydraulically, pneumatically or hydraulically.
  • pneumatically controlled piston-cylinder units should take place in such a way that the work table moves downwards after splitting the stone material and after splitting moves upwards in accordance with the return movement of the upper tool into its upper starting position, so that the lower tool is under the work surface of the work table lies.
  • the resilient support of the work table is disadvantageous for very non-uniform stones, since the table then assumes an undesired inclined position due to the corresponding non-uniform load, which leads to an undesirable fractured surface.
  • a controlled, parallel lowering of the work table during the splitting process is ensured even with very irregularly shaped and thus unevenly weighted rock.
  • the desired fracture surface is ensured.
  • the controlled lowering of the work table is also independent of the weight of the stone to be split. With very different stone weights, for example, a mere deactivation of the hydraulic support ele Mente lead to the risk that the table sinks prematurely with very heavy stones, the stone to be split tilts to one side over the lower tool and thus an uncontrolled splitting process takes place.
  • the proposed support of the work table prevents elasticities from being released after splitting, which result in the throwing up of rocks and thus an increased risk of injury to the operators.
  • the device according to the invention is preferably suitable for pre-crushing very large pieces of rock, the device preferably being part of an automatically operating stone crushing line similar to the crushing line according to FIG. 2 of US Pat. No. 4,203,414.
  • the device according to the invention is distinguished by an extremely high directional stability, in particular of the oscillating upper tools, and thus a high gap precision.
  • the rough adaptation to the structure of the top of the stone to be split takes place by means of the upper tools arranged next to one another and displaceable relative to one another in the splitting direction; the fine adjustment due to the individual riving knives that can be moved relative to each other in each splitting direction.
  • the adaptation of the upper tools and the individual riving knife assigned to them takes place spontaneously according to the invention, reference being made to EP-A-0 065 276 with regard to the constructive solution for the spontaneous adaptation of the individual riving knife to a wide variety of surface structures of the stones to be split.
  • the splitting device shown schematically in Figures 1 and 2 consists of a portal frame 12 with upper and lower cross members 28 and 30, which are designed as truss girders.
  • the frame 12 is a welded construction of a conventional type.
  • Upper and lower tools 10 and 16 which are assigned to one another, are arranged next to one another on the upper and lower cross members, with only the upper tools 10 being able to oscillate back and forth in the illustrated embodiment, or being movable toward and away from the stationary arranged lower tools 16 .
  • the upper tools each have a common linear bearing 18 on the sides facing each other, each consisting of an upright or extending in the splitting direction attached to the underside of the upper cross member 28 tion profile 24, which cooperates with arranged on the mutually facing sides of adjacent upper tools 10 guide strips or plates 26, 26 '.
  • the guide profile 24 is in the present case by two with their open sides ....
  • the outer sides of the respective outer upper tools 10 are slidably mounted in longitudinal guides 20 attached to the frame 12, these longitudinal guides being designed in a manner corresponding to the linear bearings 18.
  • the two longitudinal guides 20 have laterally outwardly open U-profile sections 34, into which guide strips or guide plates 25, which are arranged on the outer sides of the outermost outer tools, project with a clearance fit.
  • the length of the linear bearings 18 and lateral longitudinal guides 20 corresponds approximately to the maximum displacement distance of the upper tool 10. In this way, sufficient stability is ensured even when the upper tool is fully extended.
  • the common linear bearing can also be arranged by interlocking guide elements, e.g., arranged on the mutually facing sides of adjacent upper tools 10, e.g. Dovetail guide or T-guide - which, in any conceivable relative position of the upper tools 10 to one another, engage with one another over a length of at least one third of the maximum displacement distance of the upper tools in order to ensure sufficient stability of the upper tools on all sides, even on strongly inclined surfaces of the stones to be split.
  • interlocking guide elements e.g., arranged on the mutually facing sides of adjacent upper tools 10, e.g. Dovetail guide or T-guide - which, in any conceivable relative position of the upper tools 10 to one another, engage with one another over a length of at least one third of the maximum displacement distance of the upper tools in order to ensure sufficient stability of the upper tools on all sides, even on strongly inclined surfaces of the stones to be split.
  • the upper tools 10 are each attached to the underside of a piston rod 21 which is assigned to a working piston which can be pushed back and forth in the working cylinder 22.
  • Each upper tool 10 can be moved up and down individually or together, a fluid connection being present between the individual working cylinders 22, so that the upper tools can adapt spontaneously to the surface of the top of the stone to be split. If necessary, individual upper tools can be deactivated by decoupling them from the hydraulic drive.
  • the up and down movable upper tools 10 are each assigned a correspondingly designed lower tool 16, which is arranged below a work table 14.
  • the work table 14 In the area of the lower tool 16, the work table 14 has a slot-shaped opening 36 (FIG. 2).
  • the work table is supported on the frame 12 by means of hydraulically controlled piston-cylinder units.
  • the hydraulic support units When a stone pushed into the area between the upper tools 10 and the lower tools 16, the hydraulic support units are deactivated, as a result of which the work table is moved downward by the pressure exerted on the stone by the upper tools 10, so that the lower tools 16 pass through the Slots 36 in the work table 14 can be effective.
  • EP-A-0 065 276 With regard to the control of the up and down movement of the work table, reference is also made to EP-A-0 065 276.
  • the upper and lower tools assigned to one another each have individual riving wedges 38 and 40 which are movable relative to one another in the splitting direction and are preferably hydraulically supported. This enables the splitting tools to be optimally adapted to rough, uneven stone surfaces.
  • the single riving knife is in a common Z y- Linder body, which is part of the upper or lower tool, slidably mounted in the splitting direction or direction of action of the splitting tool, the cylinder spaces assigned to the individual splitting wedges and preferably filled with oil being fluidly connected to one another.
  • the lowering movement of the work table 14 inevitably takes place in time with the upper tools 10 which can be moved vertically up and down, in such a way that the work table 14 is raised during the return stroke of the upper tools 10.
  • the stone material can then be easily moved and positioned on the table top. Because of this kinematics, the device according to the invention can also be coupled very well with an automatic stone material feed, this stone feed preferably working in the same cycle as the upper tools.
  • the guide plates 26, 26 'and 25 as well as the associated guide profiles 20, 24 consist of wear-resistant material, preferably sintered material with a self-lubricating effect. Furthermore, the guide profiles 24 and longitudinal guides 20 are preferably composed of a plurality of plates and strips such that, depending on the wear of one or the other part of the guide profile or the longitudinal guide, can be selectively replaced.
  • the U-profile sections 32, 32 'and 34 are thus formed by three elongate plates which are independently fastened or screwed to frames 12 (at the lower ends of fastening brackets 58 arranged on the underside of the upper cross member 28).
