Definitions

  • the invention relates to a device for the production of profiled, plate-shaped moldings, preferably roof tiles, made of concrete or the like or the like. Filled formwork is carried out in the production direction and the moldings located therein are compacted and profiled, the compacting roller and / or the smoother having a surface made of hard metal in their surface areas subject to wear.
  • One problem with the manufacture of such a device is to bring the hard material of the support into perfect conformity with the profile of the base, in order thereby to ensure that these parts are reliably connected by welding or the like. Ensure the necessary surface contact of the connecting surfaces.
  • both its base and its support were divided into individual strips, each base strip being connected individually to a strip of the same width of the material forming the support. These strips made of different materials were then joined together to the full width of the smoothing and z. B. clamped together by bolts.
  • the object of the present invention is to remedy these deficiencies and to design a device of the type described at the outset in such a way that the above-mentioned difficulties are avoided.
  • the hard metal layer has an intermediate layer with a base, preferably made of steel, optionally with a positive fit, for example, as such, via an intermediate layer consisting of a metal-plastic mixture, preferably a steel-plastic mixture known - is connected by means of interlocking, undercut profiled tongues and grooves.
  • the hard metal support of the compacting roller or of the smoothing machine can be divided according to its profile over its entire width and can be assembled from sections.
  • This can advantageously be used for the production of roof tiles with a plurality of regions which extend over the entire width, in part domed and in part flat, in particular for the production of so-called Roman profiles.
  • a design of the device components is to be developed in which a desirably simple, robust and hard-wearing form of the hard metal supports can be used.
  • the hard metal support of the smoothing device - according to the profile of the roof tiles to be produced, which have partly curved and partly flat areas over their width - can be divided into as many flat and curved sections, which are joined together with their longitudinal edges and joined to the base.
  • the base of the compaction roller can advantageously also be subdivided according to the profile of the roof tiles into those sections which are then mounted on a common drive shaft. This results in a further advantage that such sections can be replaced or renewed individually in the event of breakage, without the need to replace the entire component.
  • separate sections of the base of the compacting roller are assigned to the curved areas, the flat areas and the area of the profiling of the roof tile provided with folds.
  • the Compaction roller is a hard metal pad attached to the base by means of the intermediate layer.
  • the sections of the arched areas can therefore consist entirely of a material that is softer than the hard metal of the supports, especially since the sections are compact and comparatively small and are not subject to any risk of breakage from the outset.
  • Figures 1 to 3 first represent the storage container 1, in which the concrete to be processed with a grain size of the aggregate of about 0 to 3 mm is fed from a mixer and in which it from the rotating distributor, for. B. a spiked roller 2, the task of which is to distribute the material evenly, is promoted under the compressor roller 3, the so-called «roller». The underside of this compacting roller 3 is also fed formwork molds 5 for the moldings 6 to be molded on a machine bed 4 (FIG. 3).
  • the formwork forms 5 filled with the compacted concrete get under the smoother 7, which is inclined at a certain angle of attack with respect to the machine bed 4 and with its end face, which is formed to a pointed edge and faces the compacting roller 3, connects tangentially directly to its underside.
  • the smoother 7 is held by a bridge 9 spanning the machine bed 4 and the conveying path of the formwork forms 5.
  • the direction of manufacture and the direction of conveyance of the formwork 5 is indicated by the arrow 10.
  • the smoother 7 shown in FIGS. 4 and 5 on a larger scale in the longitudinal and cross-section now has a base 11 made of cast or forged steel, which has an initially castable, hardenable mixture of about 80% steel and 20% Epoxy resin existing intermediate layer 12 is connected to a support 13 consisting of the so-called hard metal.
  • hard metal With hard metal is known a sintered metal hard alloy, which consists of one or more hard materials, eg. B. tungsten, titanium, tantalum carbide, etc. with a binding metal of the iron group, mostly cobalt but also nickel or iron, and has a particularly high hardness and wear resistance.
  • hard materials eg. B. tungsten, titanium, tantalum carbide, etc.
  • a binding metal of the iron group mostly cobalt but also nickel or iron, and has a particularly high hardness and wear resistance.
  • connection between the base 11 and the support 13 essentially results from the cementing by means of the intermediate layer 12, but - according to the embodiment according to FIGS. 4 and 5 - undercut profiled springs 14 and grooves 15 can also additionally be provided for the positive locking of these Connection may be provided, as shown in Fig.5.
  • the support consists of sections which correspond to the flat or curved areas of the smoothing device 7 and are connected to the base 11 with their longitudinal edges closely joined together.
  • the pad 13 could - in the context of the invention - also consist of one piece.
  • An edge part 27 of the smoothing device 7 is profiled with folds 26; it can consist entirely of hard metal.
  • the compressor roller 3 shows the construction according to the invention shown in FIG. 6, namely its base 16 consists of the sections 17, 17 ', 18 and 19 which are lined up on the drive shaft 20 and held in a rotationally fixed manner by means of a wedge 21 and a nut 22.
  • This compacting roller 3 also includes - in accordance with the profiling of the moldings 6 to be produced - partly flat, partly curved, profiled areas, namely the sections 17 and 17 'are the less stressed curved areas, the two sections 18, however, the more stressed flat areas and the section 19 assigned to the edge region of the compressor roller 3 which forms the lateral folds of the roof tile molding 6.
  • the small sections 17 and 17 ' because they are less stressed, can be made in one piece from a comparatively softer and easier to machine hard metal.
  • Sections 18 and section 19 each carry a support 23 made of harder hard metal in order to be sufficiently wear-resistant.
  • the supports 23 of the sections 18 and the support 24 of the section 19 are in turn connected to the base 16 or its sections via an intermediate layer 25 from the above-mentioned suitable metal-plastic mixture.
  • the one-piece hard metal support 13 has depressions 28 on its side facing the base 11, into which threaded bushings 29 are soldered.
  • the edge part 27 of the smoothing device, which is profiled with folds 26, also carries such threaded bushings 29.
  • the hard metal support 13 is screwed into these threaded bushings 29 and penetrates the base 11, preferably by means of so-called Allen screws, which have an angular recess in the head for rotation. connected to the base 11.
  • the smoothing device On its end facing away from the compacting roller, the smoothing device is connected by means of screws 32 to a strip 31 overlapping the edge of hard metal support 13.
  • This bar 31 made of steel, takes over part of the strong thrust forces acting on the hard metal support 13 and thereby secures its connection to the base 11 of the smoothing device 7.
  • the hard metal layer 13 of the smoothing device 7 in the edge area 13 '(FIG. 8) immediately adjoining the compacting roller 3 is made of a softer material than in the rest of the area which is more subject to abrasion, these two areas having different hardnesses in the Border zone 33 merge continuously.
  • the intermediate layers 12 and 25 of the components of the device according to the invention serve, as already explained at the outset, to compensate for the various changes in shape of the different materials from which these components are composed, and in this way prevent the occurrence of dangerous internal stresses; at the same time, they ensure reliable binding of the supports 13, 23, 24 to the bases 11 and 16 of these components.
  • the material of these intermediate layers 12 and 25 can be poured between the bases and the pads before hardening and then hardened.
  • the durability of the shaping components of the device designed according to the invention optimally guarantees a uniform, consistently high quality and extensive dimensional and weight accuracy of the moldings.
