Definitions

  • the present invention relates to a compression device for a material, which is curable in a defined shape, consisting of at least one Shape into which the material can be inserted from one to a fundamental vibration removable vibration pad on which the mold is arranged, and from a loading device with at least one stamp arranged thereon, the Stamp plate can be inserted into the mold to compress the material.
  • the entire unit formed in this way can be clamped in a production machine.
  • the lower part of the mold containing the form fields mostly rests on a so-called Underlay board, which in turn on a vibration support Vibration table is arranged.
  • the upper part of the mold representing the loading device is placed on the concrete lowered, with the punches arranged on the loading device are penetrating into the respective form fields of the lower mold part. While this process, the vibrating table is subjected to a targeted vibration, which increases the setting effect and thus the concrete is compacted.
  • the upper part of the mold only by its own load-bearing component Weight applied.
  • the earth-moist concrete is usually a mixture of cement and mineral Surcharges.
  • the latter form a grain structure, which is dried by curing cement cement is cemented.
  • the oscillation usually takes place through sinusoidal up and down movements.
  • the vibrations are generally achieved in that the vibration pad or the vibration table with appropriately designed unbalance motors or similar mechanisms.
  • vibrations to be applied vary depending on the shape to be compressed can be used to ensure proper compaction of the material, in particular to ensure earth-moist concrete.
  • From DE-PS 97 52 60 is for example a stone molding machine with a vibrating device known, in addition to the actual load device, the consists of a stamp in the form of a fall bear, on this additional vibration masses are arranged in the form of so-called auxiliary bears, which are provided there so that their movements when vibrating take place independently of those of the fall bear.
  • the auxiliary bears are guided in the fall bear so that they perform an independent vibration movement can, with which an additional compaction of the mix can take place.
  • the present invention has for its object a compression device of the type mentioned at the outset, so that basically a higher degree of compaction with the same manufacturing time and / or reduced manufacturing time is achievable.
  • the essence of the invention is to provide an additional one Oscillating mass.
  • This additional vibration mass is according to the invention in the stamp, preferably in all stamps of the loading device freely movable.
  • the vibration table is now targeted to a defined, so-called basic vibration
  • the loading device is also subjected with the stamps arranged thereon, the stamp plates each in the Form fields of the form are introduced under the own weight, this defines Fundamental vibration exposed.
  • the one freely movable in the stamps Vibration mass is therefore also due to the fundamental vibration excited.
  • this has the effect that in one, preferably only in one Direction of the up and down movement of the vibration table or the vibration pad, the additional vibration mass, especially on the End of the downward movement of the sinusoidal fundamental, an additional one Impulse on the stamp and thus on the one to be compressed in the mold field Exerts material. It can be seen that this results in the same manufacturing time a much higher degree of compaction can be achieved. However, can the production time even with a defined degree of compaction thereby significantly reduce, which increases the quality of the hardened stones and reducing costs at the same time.
  • the vibration mass contained in the hollow stamp the additional vibration can be moved up and down, either from a single one Vibrating body or consist of several vibrating bodies.
  • a single vibration mass is advantageous axially guided in the hollow stamp.
  • Possible designs are for example a rod guide arranged in the center of the stamp or in groove guides arranged on the inner surface of the stamp, on which the Vibration mass with complementary sliding mechanisms arranged thereon slides.
  • the vibration mass for example around a ball guided axially in the stamp.
  • the vibration mass but also accomplish that several balls, possibly with different diameters, freely movable in the hollow stamp are.
  • the density of the Material of the vibration mass i.e. for example the number of balls, as well the total mass of the vibration mass selected.
  • Degree of compaction and depending on the material to be compacted forms here an interrelation between the individual parameters, which are defined by the expert can be determined empirically if necessary.
  • the vibration path which is determined by the height of the hollow stamp determined depending on the above parameters selected.
  • the stamp with at least to provide a closable opening for changing the vibration mass.
  • the device is thus intended in particular for compression or in the production of concrete blocks from earth-moist concrete.
  • FIG. 1 shows a compression device which is well known from the prior art 1, as used for example in a concrete block making machine Commitment comes.
  • This compression device 1 consists of several stamps 2, which are arranged on a load device 3.
  • a molding box 4 which has several mold fields 5 for receiving the material to be compressed, here in square Reproduced shape.
  • the molding box 4 is in turn arranged on a vibration pad 6, the via vibration mechanisms, not shown, for example unbalance motors, can be selectively set into an oscillation, which is preferably in Moved up and down in the direction of the longitudinal axis of the stamp 2.
  • the load device 3 with the stamps 2 is relative to the vibration pad 6 can be swiveled or moved in order after the mold fields 5 have been the material to be compressed and hardened, the stamp penetrate into the respective mold fields 5 under the load of the load device 3 allow.
  • FIG. 2 shows an example of a stamp 2, which consists of a stamp plate 7, which is attached to a pipe like a flange, the shape of which, of course Stamp plate 7 is complementary to the shape of the mold field 5.
  • a concrete mass 8 to be compacted is introduced into the mold field 5, so that the Stamp plate 7 with a targeted force F the concrete mass 8 in the mold field 5 squeezes.
  • FIG. 3 shows the known stamp arrangement from FIG. 2 in cross section, wherein according to the invention the hollow stamp tube an additional Vibration mass 11 has taken up.
  • the Stamp plate 7 of the stamp 2 attached to the tube via a pressure plate 9.
  • the stamp plate 7 is removable and places a filling opening 10 in the pressure plate 9 free, which serves to replace the vibration mass 11 and with a closure is lockable.
  • the vibration mass 11 is at lower end of the stamp 2, i.e. at the time when the additional Vibration mass 11 a further additional compression pulse on the Pressure plate 9 and the stamp plate 7 exerts on the concrete mass 8 to this to condense in addition.
