Definitions

the invention relates to a device for producing concrete moldings.
Devices for the production of concrete moldings such.
paving stones are typically used for machining and contain a molding machine and a mold with a mold base and a stamp unit.
the lower mold part usually one or more mold cavities are formed, which are open up and down.
the mold base is placed with a lower boundary plane of a stone field on a horizontal surface, which closes the lower openings of the mold.
the mold nests are filled with concrete amount, which is then pressed through arranged on the stamp unit printing plates in which the printing plates are sunk through the upper openings in the mold cavities. Connecting is done by shaking typically the pad a solidification of the concrete amount to form-stable concrete moldings. These are removed from the mold through the lower openings of the mold cavities.
the stamp unit is connected to a typically hydraulically actuated vertical movement unit of the molding machine and by means of this vertically movable.
the connection can be given in conventional construction via a Auflastü, which usually forms with the stamp unit a Formoberteil as uniformly manageable assembly.
a uniform stone height is achieved even with different compression of the concrete amount.
a device for the production of concrete blocks in which a plate-shaped functional device is provided, which contains, in addition to a stamp plate for connecting a plurality of stamp tubes a connecting plate assigning a loading device.
the stamp plate and the connecting plate are connected to each other via connecting means comprising elastically deformable damping elements.
the damping elements allow relative movement between the connecting plate and the stamp plate, wherein the maximum vertical displaceability limited by the damping elements is greater than a gap between the stamp plate and stop elements on the connecting plate.
swinging pressure plates are known in which a vertically limited displacement, for example, between a lower mounting plate, which is connected to the pressure plate, and an upper mounting plate can be provided. It has been shown that such vibrating mounted printing plates cause better compaction results, especially in large-scale and difficult to compact products. In particular, swinging pressure plates prevent uneven Take off in large stone fields, while still optimally exploiting the vibrations in the stone field during jogging.
an apparatus for the production of concrete moldings is provided with a molding machine and a changeable arranged in this form, comprising a mold base with one or more mold cavities and a mold top with a pressure plate assembly with one or more the mold cavities facing pressure plates, wherein the mold top relative to the lower mold part is displaced so that the pressure plates when compressing a filler in the lower mold part along a gap against a restoring force of an elastically deformable damping element to an outer edge of a stop element vertically by means of a stamped and connected to this with an intermediate plate stamp plate are displaceable, wherein the stop element is formed hollow and in its interior, the damping element is arranged.
the solution according to the invention provides for a damping element to be provided between a pressure plate and an intermediate plate, which ensures contact with the pressure plate, for example, with a concrete amount during insertion of the pressure plates into a lower mold part for vertical and / or horizontal mobility of the pressure plates.
the stop element which is formed according to the invention as a hollow body. Under hollow body is understood here an arrangement in which an interior is surrounded by a side wall which is formed in the form of a continuous surface. Accordingly, openings, recesses, slots or the like may be present in the side wall or at the edge of the side wall.
a shaped stop element would always be understood as a hollow body according to the invention.
the stop element as a hollow body, it is possible that the damping element can be mounted inside the hollow body. Accordingly, a compact design is achieved, which also has other advantages beyond. While in conventional solutions in which, for example, alternately damping elements and abutment elements between the intermediate plates and the pressure plates are mounted, bending moments can occur in the intermediate plates, this is greatly reduced according to the invention, since the force in the intermediate plate in limiting the attack from the point to to the reaction force only one has little way. Furthermore, the inventive design of the stop element can produce more cost-effective, since the stop elements can be provided together with the damping elements as prefabricated modules, in particular no over-milling of the stop elements must be performed more, as is usually provided in the prior art.
stop elements are usually welded, so that for the exact definition of the minimum distance post-processing is necessary.
the solution according to the invention is advantageous in that no force flow has to take place via weld seams. Accordingly, the invention makes it possible to provide a compact construction between printing plates and intermediate plates, so that vibration-mounted printing plates can be used, for example, even with smaller dimensions.
each pressure plate is provided in each case with its own intermediate plate and beyond also with its own stamp plate. Accordingly, compact sub-components of a device for the production of concrete moldings are created, which can be performed together, for example, in the usual way with the other components of the mold tops or Auflast wornen.
This structure makes it possible to replace, for example, complete printing plates for whole stones by those for semi-stones.
the gap between the outer edge of the stop element and the intermediate plate is arranged.
the stop element may preferably be connected to the pressure plate via a screw connection.
the gap between the outer edge of the stopper member and the pressure plate is arranged.
the stop element may be connected to the intermediate plate via a screw connection.
the stop element is designed as a hollow cylinder.
the stop element can be formed in a simple manner, for example by a suitably cut pipe section, so that a simple and cost-effective production of the device according to the invention is possible.
the term "hollow cylinder” also means an arrangement in which also openings, recesses, slots or the like in the side wall or at the edge of the side wall of the hollow cylinder can be present. Such a shaped stop element would always be understood as a hollow cylinder according to the invention.
the stop element on a side opposite the gap on the outer edge a closing body, preferably in the form of a welded plate, wherein the closing body for attachment of the damping element and / or for attachment of the stop member provided with a preferably centrally mounted bore is.
the z. B. acts as a lid in the form of a welded plate.
the closing body can be equipped with a corresponding bore both for fastening the damping element and for fastening the stop element, so that attachment to either the intermediate plate or the pressure plate is possible.
the damping element may be provided with a threaded rod which extends through the usually centrally mounted hole so that it can be fixed on the opposite side with a nut or the like.
a corresponding bore may be provided which receives a cylindrical continuation of the damping element.
the damping element comprises a resilient body, which is preferably designed as a cylindrical rubber body or as a spring.
the stop element and the damping element form a single assembly.
the design of the stop element and the damping element as nested components makes it possible to form a prefabricated assembly of these two elements, which can be attached to the intermediate plate of the device for the production of concrete moldings.
the stop element is produced with a suitably selected height and provided with the correspondingly larger selected damping element, so that there is the above-described gap on the outer edge of the stop element.
Such assemblies produced can then be bolted to intermediate plates, so that, for example, a retrofit in machines for the production of concrete moldings would be possible.
stop elements In order to achieve a stable construction, usually several stop elements are used with corresponding damping elements. These are positioned and their number is chosen so that depending on the geometry the static pressure of the pressure plates is uniform or nearly uniform.
four stop elements are provided in pressure plates with a rectangular or square base surface, wherein the four stop elements are arranged in intermediate spaces of the preferably four punches of the intermediate plate.
the stop elements symmetrically in those areas where above the intermediate plate no punch abut, connecting the intermediate plate with the die plate, since thus the mounting of the intermediate plate on the stamp plate on the one hand and the mounting of the intermediate plate and the pressure plate or
the lower mounting plate can be made independently of one another, whereby the above-described uniform or nearly uniform surface loading is achieved.
four punches for example, which are formed in a square or rectangular arrangement between the intermediate plate and the stamp plate. The four stop elements with their damping elements can then come to lie in the spaces between the four punches, so that there is a diamond-shaped arrangement of the stop elements.
the exemplary embodiments given in these embodiments enable a force transmission over the stop element in a small area and over a direct path, whereby additional bending moments in the intermediate plate are reduced compared to the devices known from the prior art.
a device VO is shown, which is suitable for the production of concrete moldings in a molding machine.
the device VO has a replaceably arranged form FO, which is formed by a lower mold part FU and a upper mold part FB.
the lower mold FU has a mold cavity FN, which has a correspondingly selected number of openings OE, so that concrete moldings in the desired number or size can be produced with the device FO.
the upper mold part FB has a plurality of printing plates DP, each printing plate DP corresponding to one of the openings OE.
the printing plates DP are each connected via a plurality of punches SP with a stamp plate ST.
a loading device AE which can correspondingly compress a concrete quantity introduced as filling material into the openings OE of the mold cavity FN via the punches SP.
a lower mounting plate AU and an intermediate plate ZW is arranged, wherein the pointing in the direction of the mold cavity FN vertical movement of the pressure plates DP initially takes place against a restoring force of a damping element DA until the lower mounting plate AU in contact with a stop element ON device.
the damping element DA is fixed by means of screw SC1 to the intermediate plate ZW.
the pressure plates DP are connected to the lower mounting plate AU via further screw connections SC2.
FIG. 2 is a perspective side view of a portion of the device VO according to a first embodiment of the invention explained in more detail.
the in Fig. 2 shown part corresponds to that part below the loading device AE in Fig. 1 which is associated with a single printing plate DP.
the representation of the lower mold part FU has also been dispensed with.
the stamp plate ST which is connectable, for example via the screw SC3 with the loading device AE, four punches SP are associated, which are connected to the intermediate plate ZW, so that a force exerted on the punch plate ST force on the punch SP on the Intermediate plate ZW is transferred.
the lower mounting plate AU which are connected to each other via screw SC2.
the intermediate plate ZW and the lower mounting plate AU are not in Fig. 2 shown damping elements DA connected, wherein the damping elements DA are arranged in the interior of the hollow-shaped stop members AN.
damping elements DA are arranged in the interior of the hollow-shaped stop members AN.
four stop elements AN are provided, which are arranged in spaces of the punches SP on the other side of the intermediate plate ZW. Accordingly, it is possible to be able to produce a connection between the intermediate plate ZW and the damping elements DA arranged within the stop elements AN via the screw connections SC1.
Fig. 3 is the in Fig. 2 shown part of the device VO explained in more detail in a sectional view.
the stop elements AN have a hollow cylinder HZ as a side wall, which communicates via a welded connection with a closing element AB with the underside of the intermediate plate ZW.
the damping element DA Inside the stop element AN is the damping element DA, which is held on its upper side in the direction of the intermediate plate ZW through a bore in the closing element AB by means of the screw SC1 on the intermediate plate ZW.
Fig. 4 is again a cross-sectional view, the in Fig. 3 drawn detail area B shows enlarged.
the closing edge AK at the lower side of the hollow cylinder HZ facing the lower mounting plate AU formed the slot SL in the uncompressed state of the damping element DA.
the dimensioning of the slot SL, ie the distance between the end edge AK and the lower mounting plate AU is selected as a function of the spring constant of the damping element DA.
this distance may be for example 1 mm.
Number and dimensions of the stop elements AN and the damping elements DA are selected so that the most uniform possible static surface load acts on the printing plates DP.
different base constants of the damping elements DA or different dimensions of the stop elements AN can be selected, in particular in the case of base surfaces of the pressure plates DP which have no mirror symmetry.
a diameter of the stop element AN is in the range of 50 mm to 200 mm, preferably about 75 mm.
the stop element may have an area in the region of the end edge which is approximately 1000 mm 2 to 3000 mm 2 , in particular approximately 2000 mm 2 .
the centrally mounted bore BO in the end element AB is in accordance with the plan view Fig. 6 refer to.
the individual parts, such as threaded extension FR and threaded rod GS and the different heights of the damping element DA and the hollow cylinder HZ to form the gap SL are in the sectional view of Fig. 7 shown again.
Fig. 8 differs from the first embodiment according to the Fig. 2 to 7 in that the gap SL no longer points between stop element AN at the closing edge AK of the hollow cylinder HZ in the direction of the lower mounting plate AU, but rather is now mounted on the opposite side in the direction of the intermediate plate ZW. It can be provided to replace the previously performed in one piece intermediate plate by a multi-part structure, so that in connection with the Fig. 2 explained lower mounting plate AU is displaced in the direction of the intermediate plate ZW.
