Definitions

  • the invention has as its object an extrusion gun of the kind mentioned in the introduction How to create cartridges of different diameter and type Different types are suitable, which additionally a considerable Ease of use, regardless of the cartridge type, of the extruded Material and working and environmental conditions.
  • the invention proposes the use of a Extrusion gun before which is suitable, be it in the same receiving trough
  • a cordless screwdriver or a any hand drill preferably with rechargeable batteries, is driven, this being easy attachable and a stepless Adjustment of extruding speed or extruding volume without that thereby the user fatigues, so that this exclusively on the can concentrate on professionally performing the work.
  • the Extrudierpistole invention consists essentially of a housing, From thrust organs, from gears for transmission, conversion and the Slowing the movement, from a mechanical release device in order to restore the readiness to charge and elements for the Connection and attachment of the cordless screwdriver.
  • the housing consists of two shells which form the recess in the upper area for the use of the cartridges and for the storage of the pushrod.
  • the receptacle for a front reduction gear with cylindrical spur gears and for supporting the input shaft for connecting the drill bit of the cordless screwdriver which is easily attachable and replaceable, for receiving a rear worm reduction gear and the transmission mechanism for the push rod and for the mechanical release device to restore readiness for charging.
  • the housing at the bottom of a receiving trough for the back of the cordless screwdriver, a mounting bracket for the cordless screwdriver and a pivotable cover for the drill chuck of the cordless screwdriver, on.
  • the invention proposes to realize the reduction and the conversion of the rotary motion of the cordless screwdriver by means of two reduction gears, which are provided at the front and at the rear of the extruder gun and are connected by a longitudinal connecting shaft , which is provided in the region between the receptacle for the cartridges and the back of the cordless screwdriver; this connecting shaft runs parallel to the longitudinal axis of the receiving trough and to the axis of the drill chuck of the cordless screwdriver.
  • the front reduction gear advantageously made of cylindrical Spur gears consists and at the bottom of a storage Input shaft provides at which the chuck of the cordless screwdriver attached
  • the rear reduction gear comprises a worm gear, the pinion which mesh with the rack-shaped parts of the pushrod and a by pressing a button operated release mechanism for the purpose of restoring the Ready to load with each cartridge change.
  • the end-side adapter also includes a frontal support wall with bore on which the cartridge rests with plugged Extrudierdüse.
  • the thrust member according to the invention consists of three mutually parallel push rods of which the two outer have a rack and thus the drive rams are connected while the middle ram at the rear end portion fixed to the rack rams and thus moved together with them.
  • the rack rams are connected by a thrust ring which, in the case of coaxial cartridges, acts on the annular piston of the annular container of the cartridge while the central ram acts on the piston of the middle container.
  • This thrust ring and possibly also the support of the central plunger are interchangeable to adapt to the different dimensions and types of cartridges.
  • the Ausklinkmechanismus which makes it possible to restore readiness for loading with each cartridge change, according to the invention consists of a pair of axially displaceable gears which transmit the movement of the worm on the racks of the push rod. These axially displaceable gears are in engagement position on the worm, or on which, to the pinions which mesh with the racks of the plunger, coaxial gear, secured by a compression spring and can be brought by pressing the release button in notch position.
  • Actuation of this button causes the pair of interconnected coaxial gears to be displaced along the bearing axis by compressing the aforesaid compression spring and interrupting the mechanical transmission of movement between the worm and the pinions meshing with the racks of the outer pushrod as long as the release button is depressed is held.
  • the pushrods can be easily withdrawn by only rotating the pinions and the corresponding drive gear without having to rotate all the gears of the extruder gearbox together with the reduction gear and the cordless screwdriver motor, thereby exerting a self-locking effect would.
  • the invention includes that the number, type and arrangement of Gear, or the bearing axes may be different.
  • a protective shell according to a transverse axis pivotally provided which is suitable in mounting position of the cordless screwdriver whose chuck cover.
  • the invention does not exclude the use of adapters around the Receptacle to the back area of the different models and To adjust the dimensions of the cordless screwdriver, further, the input shaft with be provided an elastic coupling which is suitable deviations of Coaxiality between chuck and bearing of the input shaft to compensate.
  • FIG. 1 is a side view of a cordless screwdriver which is connected to a Extruder gun according to the invention is coupled with inserted cartridge;
  • the Extrudierpistole according to a, in Fig. 2 drawn, cutting plane I-I which through the axis of the cartridge and through the axis of the drill chuck runs, shown in longitudinal section.
  • Fig. 2 is a plan view of the driven by a cordless screwdriver Extrusion gun, as shown in Fig. 1.
  • FIG. 3 is the cross-section according to the sectional plane III-III shown in FIG by the extrusion gun as shown in Figs. 1 and 2.
  • the Extrudierpistole invention consists of a housing 12 which from two essentially mirror-like shaped composite shells consists, which in the upper part of a receiving trough 12a for insertion cartridges C and in the lower part of a trough for the back of a Cordless screwdriver T with drill chuck M, train.
  • a receiving trough 12a for insertion cartridges C and in the lower part of a trough for the back of a Cordless screwdriver T with drill chuck M, train.
  • To the receiving trough for the Use of cartridges of different diameters and different Longitudinal extensions are accommodated in these replaceable adapters 12b insertable from those of the front area a frontal platen 12c having a central through bore into which the extrusion nozzle of the Cartridge C can be used.
  • the worm wheel 5a engages which one with the coaxial Gear 5b is integral; the storage of these gears runs transversely at an angle of 90 ° with respect to the axis 4 of the screw.
  • the worm wheel 5a together with the gear 5b axially slidably disposed 15a and by the action of a coaxial with the axis. 5 plugged compression spring 16 held in the engaged position.
  • a release button 15 slidably mounted 15 a which laterally through a breakthrough in the housing 12 protrudes.
  • the push rod rams 7 are, together with a parallel to this and centrally arranged push rod 7a, axially displaceable A to, supported by the housing 12 bearing elements 11, stored.
  • the rack rams 7 and the central push rod 7a are connected in the rear area via a connecting plate 8 which is provided with a pull handle 9; in the front area, however, the two rack rams on a possibly interchangeable thrust ring 10.
