Definitions

  • the invention relates to a device for producing profiled, plate-shaped moldings, preferably roof tiles, made of concrete or the like. abrasive material by means of a rotatably mounted compacting roller and a shaping and fixed smoother directly adjoining it in the production direction, below which or the like with the concrete. filled formwork forms in the production direction and the moldings contained therein are compacted and profiled.
  • the compacting roller and / or the smoothing have in their surface areas subject to wear a pad made of hard metal.
  • the hard metal layer is connected to the base, which preferably consists of steel, via an intermediate layer consisting of a metal-plastic mixture, preferably a steel-plastic mixture.
  • the hard metal support can also be connected to the base in a form-fitting manner, for example by means of interlocking, undercut profiled tongues and grooves.
  • Another problem is that hard metal is relatively difficult to process into more complicated shapes.
  • the subject of the invention is therefore also the design of the components of a device according to the invention, which is specifically intended for the production of roof tiles with a plurality of regions that extend over the entire width, partly domed and partly flat, in particular for the production of so-called Roman products filen.
  • the aim of the invention is to develop a design of the device components in which a desirably simple, robust and hard-wearing form of the hard metal pads 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 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.
  • 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.
  • Edge area of the compaction roller is a hard metal pad that is attached to the base by means of the intermediate layer.
  • the sections of the curved areas can therefore consist entirely of a material that is softer in comparison to 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.
  • a hard metal support preferably in one piece, can have depressions in the context of the invention on its side facing the base or in the edge portion of the smoother profiled with folds , are screwed into the threaded bushings, and the hard metal support can then be connected to the base by means of screws screwed into these threaded bushings which penetrate the base, preferably Allen screws.
  • this smoothing device can also be connected at its end facing away from the compacting roller to a strip overlapping the edge of the hard metal support, e.g. by means of screws.
  • the hard metal coating of the smoothing device in the edge area immediately adjacent to the compacting roller can be made of a softer material than in the rest of the area that is more subject to abrasion, these areas of different hardness continuously in a boundary zone merge.
  • Figures 1 to 3 first represent the storage container 1, into 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 is separated from the rotating distributor, e.g. a spiked roller 2, the task of which is to evenly distribute the material, is conveyed under the compression roller 3, the so-called “roller”.
  • the formwork molds 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 formed towards a pointed edge facing the compressor roller 3 directly on its side Bottom connects tangentially.
  • the smoother 7 is held by a bridge 9 spanning the machine bed 4 and the conveying path of the formwork 5.
  • the direction of manufacture and the direction of conveyance of the formwork 5 is indicated by the arrow 10.
  • hard metal is a sintered hard metal alloy that consists of one or more hard materials, e.g. Tungsten, titanium, tantalum carbide etc. with a binding metal of the iron group, mostly cobalt but also nickel or iron, is made and has a particularly high hardness and wear resistance.
  • hard materials e.g. Tungsten, titanium, tantalum carbide etc. with a binding metal of the iron group, mostly cobalt but also nickel or iron, is made 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 - in accordance with the embodiment according to FIGS. 4 and 5 - additionally also undercut profiled springs 14 and grooves 15 can be made be provided for the positive locking of this connection, as shown in Fig.5.
  • the support consists of parts which correspond to the flat or curved areas of the smoothing element 7 and are joined 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 one shown in FIG Construction according to the invention, namely its base 16 consists of the sections 17, 17 ', 18 and 19, which are lined up on the drive shaft 20 and are 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 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 compression 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 manufactured in one piece from a comparatively softer and easier-to-work hard metal.
  • the mutually identical sections 18 and section 19 must each have 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 bearing 13 is screwed into these threaded bushings 29 and screws 30 penetrating the base 11, preferably by means of so-called Allen screws, which are used to rotate the head have angular recess, 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 shear forces acting on the hard metal support 13 and thereby secures their connection to the base 11 of the smoothing device 7.
  • the hard metal layer 13 of the smoothing device 7 in the edge region 13 '(FIG. 8) immediately adjoining the sealing roller 3 consists of a softer material than in the rest of the region which is subject to higher abrasion, these two regions having different hardness continuously merge into each other in the border zone 33.
  • the intermediate layers 12 and 25 of the components of the device according to the invention serve - as already explained at the beginning - 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 internal hazards Tensions; 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 supports before hardening and then hardened.
