Definitions

  • the present invention relates to an ejection gun for double-wall cartridges, consisting of a manually operated pistol grip, a trough-shaped half-shell, a piston rod slidably mounted therein and an essentially circular ejection plate arranged at the front end of the piston rod.
  • Such an ejection gun for double-wall cartridges which additionally has a cylindrical tube that is detachably and displaceably mounted in the trough-shaped half-shell and in which two semi-cylindrical stamps, which are arranged at a distance from one another and are symmetrical about a longitudinal axis of the tube, are fastened, is disclosed in EP-A -363,967, whose priority date is before the priority date of the present patent, but whose publication date is after the filing date of the present patent.
  • the two chambers of a double-walled cartridge can be squeezed out precisely without irregular widening of the outer wall of the cartridge occurring, the double-walled cartridges being divided into two opposing symmetrical chambers, each with a semicircular cross-section, by a flat partition wall that penetrates the longitudinal axis of the cartridge.
  • the two punches have the shape of a cylinder jacket section, whereas the double-wall cartridge which is enclosed by this tube is divided by a partition into two semicircular chambers, in each of which a pasty mass is arranged.
  • the two punches are spaced apart and symmetrical to one another arranged such that the partition of the double wall cartridge engages in the gap formed between them.
  • a hand-operated sealing pistol which is used to squeeze out a double-wall cartridge, a trough-shaped half-shell being arranged on the front side of a hand-operated pistol grip.
  • a piston rod Parallel to a transport rod, a piston rod is fastened via a yoke, with half a piston disc being located at the front ends of the transport rod and the piston rod, so that simultaneous pressing of the two components from the double-wall cartridge takes place when the transport rod and the piston rod are actuated simultaneously.
  • a disadvantage of this known sealing gun is that at the high pressures required to move the pasty masses in the chambers of the double-wall cartridges, the individual cartridge chambers expand laterally, since this lies loosely in the trough-shaped half-shell and is usually made of a flexible material.
  • a detachable and displaceably arranged, one-sided open cylindrical tube is provided in the trough-shaped half-shell, in which two spaced stamps are fastened, the stamps having the shape of a cylinder and coaxial to one another and to the longitudinal axis of the tube are attached to the tube sheet.
  • the double wall cartridge 1 shows a longitudinal section through a double-wall cartridge 1, which is provided with an outlet opening 2 and a mixing tip 3 which can be screwed thereon.
  • the double wall cartridge 1 is divided by a cylindrical partition 4 into two chambers 5, 6, in each of which a pasty mass is arranged.
  • the cylindrical partition 4 separates an inner cylindrical chamber 5 from an outer annular chamber 6 surrounding it.
  • the cylindrical chamber 5 is closed by a cylindrical piston 8 and the annular chamber 6 by an annular piston 7.
  • the two pistons 7, 8 are slidable towards the outlet opening.
  • a conventional dispensing gun (not shown) which consists of a manually operated pistol grip, a trough-shaped half-shell, a piston rod slidably mounted therein and a substantially circular ejection plate arranged at the front end of the piston rod, a cylindrical tube 9 open on one side, in which two coaxially to one another and to the longitudinal axis 12 of the cartridge 1 are inserted Arranged in cross section circular stamps 10, 11 are attached.
  • the cylindrical tube 9 is closed at its end 13 assigned to the ejection plate of the ejection gun, the two cylindrical punches 10, 11 being attached to this base (FIG. 2), the longitudinal extent of which is less than that of the cylindrical tube 9.
  • the two punches 10, 11 are dimensioned such that the inner circular punch 11 acts on the circular piston 8, which closes the inner cylindrical chamber 5 and the second punch 10 arranged coaxially thereto acts on the annular piston 7, which closes the annular chamber 6.
  • the cylindrical tube can be made of plastic or metal, such as. As aluminum, exist, wherein it is adapted in its outer diameter to the inner diameter of the trough-shaped half-shell of the firing gun, and its inner diameter is adapted to the outer diameter of the double-wall cartridge 1 to be pressed out.
