Definitions

  • the present invention relates to a method for manufacturing a barrel with an integrally subsequent housing for a closure head.
  • the invention has for its object to overcome the disadvantages of the known prior art and to provide a method for producing a barrel with integrally subsequent housing, which allows a reduction of the manufacturing costs and at the same time increasing the material strength.
  • the hammering (cold forging) of a running blank on a hemming mandrel corresponding to the inner race profile (blacksmith's mandrel) is used worldwide for the production of barrels in the weapons industry due to the high achievable precision and economic production.
  • the hammering leads to an increase in strength of the base material and a significant extension of the life of the barrel.
  • the invention uses hammering for the first time for the manufacture of a housing integrally connected to the barrel, so that this too experiences the increase in strength of the cold forging operation and, moreover, can be produced in a single operation on the same hammering machine without unseating the blank.
  • the first hammer mandrel after the first hammering removed from the through hole and then the second hammer mandrel for the second hammering are introduced into the through hole.
  • the first hammers mandrel is held during the first hammering with a holding rod which is passed through a central bore of the second hammers mandrel.
  • the second hammer mandrel does not need to be removed during hammering, ie the hammering can be carried out continuously from the barrel mouth over the barrel to the housing.
  • first hammer mandrel for the second hammering is at least partially withdrawn into the central bore of the second hammer mandrel, so that the first hammer mandrel (hammer hammer) when hammering the housing on the second hammer mandrel (housing hammer mandrel) not in the way.
  • the diameter transition between the first and the second hammer mandrel is large and the formation of a sharp inner shoulder between the housing interior and barrel bore or cartridge chamber during hammering is not allowed, can additionally after the first or after the second hammering the through hole in the transition region between the first and second longitudinal section machining to be edited. This can also be used to create an undercut for locking the closure head in the housing.
  • the closure-side end region of the first longitudinal section can be formed by machining to form a cartridge chamber.
  • the cartridge chamber is also hammered, namely by hammering after the first and before the second hammering of the closure-side end portion of the first longitudinal portion on a cartridge chamber forming part of the first hammer mandrel.
  • the second hammering is preferably carried out in the direction from the first longitudinal section so as not to interrupt the continuity of the hammering operation from the mouth of the barrel.
  • the invention provides a hammer mandrel assembly for carrying out the method of the present invention, comprising: a first hammer mandrel having a peripheral portion corresponding to the race inner profile and fixed at one end to a reduced diameter support rod, and a second hammer mandrel having a peripheral part corresponding to the housing inner profile and provided with a central bore, wherein the support rod is guided in the central bore of the second hammer mandrel.
  • the housing can be hammered directly in a single hammering process with the running hammers, which not only greatly simplifies the production, but also significantly increases the precision of the one-piece arrangement of housing and barrel.
  • the first hammer mandrel is at least partially retractable into the central bore of the second hammer mandrel to facilitate removal of the hammer mandrel assembly from the through bore after the second hammering.
  • the hammers mandrel arrangement is also designed to hammer the cartridge chamber of the barrel by the first hammer mandrel has a first part corresponding to the inner race profile and a subsequent second part corresponding to the cartridge chamber.
  • the second hammer mandrel has Leksriefen. In conjunction with a final milling out of an undercut in the closure housing, this results in a kind of bayonet groove in the closure housing into which a closure head provided with radial lugs is inserted and can be locked by rotation (rotary piston closure).
  • a barrel 1 for a firearm is shown, eg a rifle, integrally connected to a housing 2 for further components of the weapon.
  • the barrel 1 has in known manner an orifice 3 and a bore 4, the rear, the mouth 3 remote end portion is extended to a chamber 5.
  • the housing 2 accommodates a closure head for the barrel 1, e.g. a (not shown) rotary piston closure which is inserted with sprocket-like radial extensions in axial réelleriefen 6 of the housing 2 and locked in the fully inserted, the cartridge chamber 5 closing position by twisting its extensions relative to the grooves 6 in an undercut 7 bayonet-like.
  • a closure head for the barrel e.g. a (not shown) rotary piston closure which is inserted with sprocket-like radial extensions in axial réelleriefen 6 of the housing 2 and locked in the fully inserted, the cartridge chamber 5 closing position by twisting its extensions relative to the grooves 6 in an undercut 7 bayonet-like.
  • the housing 2 for this purpose may have corresponding openings, in particular on its underside, for the passage of a magazine shaft and a trigger device, as known in the art.
  • any front ends of the housing 2 on its back for example, covers and guides for the in its movement to the rear emerging rotary piston closure, not shown in detail.
  • the considered here, one piece on the barrel 1 attaching housing 2 can be considered in this sense as a housing semi-finished part, which can be supplemented or modified by other housing components.
  • the barrel 1 together with the housing 2 is made by hammering (cold forging) on a hammer mandrel assembly 10 comprising a first hammer mandrel 11 for the barrel 1 and a second hammer mandrel 12 for the barrel 2 in a barrel hammer machine, as will be described with reference to FIGS Fig. 4 and 5 will be explained in more detail.
  • the first (running) hammer mandrel 11 in turn consists of a first part 13 corresponding to the inner profile of the barrel 1 and a subsequent second part 14 corresponding to the inner profile of the cartridge chamber 5.
  • the barrel hammer mandrel 11 is held by a support rod 15 at its rear end during hammering.
  • the inner race profile part 13 of the barrel hammer mandrel 11 may be provided on its outer side with helical ridges or grooves 16, as is known to those skilled in the art, to form trains in the barrel 1.
  • Both the inner race profile part 13 and the cartridge bearing part 14 of the barrel hammer mandrel 11 are each slightly conical, slightly widened towards the rear, in order to "tightly pack" the barrel during the relative movement of the barrel hammers 11 through the barrel 1 To avoid hammer thorns 11.
  • the housing hammers mandrel 12 of the hammers mandrel assembly 10 forming the inner profile of the housing 2 may be a completely separate component from the hamming mandrel 11, or may be penetrated by the support rod 15 of the hamming mandrel 11, as shown herein. this is slidably guided in a central bore 16 of the housing hammer mandrel 12.
  • the barrel hammers mandrel 11 may also ladel only from the first part 13 for forming the inner race profile exist, ie the cartridge chamber part 14 may be omitted. Further, the barrel hemming mandrel 11 may be provided at its rear end, be it the first part 13 or the second part 14, if any, with a tapered shoulder 17 which is insertable into the central bore 16 of the housing hammer mandrel 12 to partially retract the barrel hammer mandrel 11 into the housing hammer mandrel 12 while leaving a defined protrusion of the barrel hammer mandrel 11 over the face of the housing hammer mandrel 12. If desired, the barrel hammer mandrel 11 may also be telescopically retracted into the housing hemming mandrel 12 or even withdrawn therethrough and rearwardly out of the housing hemming mandrel 12.
  • the housing hammers mandrel 12 is provided on its outer periphery with longitudinal grooves 18 and remaining therebetween longitudinal webs 19, so as to form the mecanicriefen 6 of the housing 2, which serve in cooperation with the undercut 7 of the bayonet lock of the closure (closure head).
  • Fig. 4 shows a first embodiment of the method for producing the barrel 1 with the housing 2 using two separate barrel and housing hammers mandrels 11, 12.
  • a first step ( Fig. 4a ) is assumed by a cylindrical blank 20 having a through hole 21 whose inner diameter D 1 is at least as large as the maximum outer diameter of the housing 2 to be accommodated closure or closure head, and thus also at least as large as the maximum outer diameter of the housing hammer mandrel 12th
  • the barrel 1 (optionally with the chamber 5) is forged, and from a subsequent second longitudinal section 20 ", the housing 2 is forged, as will now be explained in detail.
  • the barrel hammer mandrel 11 held on its support rod 15, and introduced with the blank 20 between the forging hammers 22nd a (not shown) Laufnosmmermaschine positioned ( Fig. 4b ).
  • four forging hammers 22 are usually used around the circumference of the blank 20 and hammer periodically and simultaneously on the blank 20 from the outside to strictlyschmieden the blank 20 on the barrel hammer mandrel 11, while the hammers 22 and the Hammers mandrel 11 are advanced from mouth 3 in the direction of arrow 23 relative to blank 20 (typically, hammers 22 and mandrel 11 remain stationary and blank 20 is moved counter to the direction of arrow 23).
  • the barrel hemming mandrel 11 is simultaneously rotated in order to leave 16 by means of its grooves helical trajectories in the thus generated bore 24 of the barrel 1, as known in the art.
  • the cartridge chamber 5 can be further forged by stopping the barrel hamming mandrel 11 against the blank 20, and thereby exposing its cartridge bearing member 14 (not shown)
  • the cartridge chamber 5 can be produced by a separate machining of the through hole 21, for example, by milling, both equally or only after completion all hammers steps.
  • the housing hammer mandrel 12 is then inserted into the through-hole 20 and the housing 2 hammered or forged thereon, see Fig. 4c ,
  • the transition region between barrel 1 and housing 2 can be machined after hammering the barrel 1 and before hammering the housing 2, not only to mill the cartridge chamber 5, but also to form a defined internal shoulder 25 in the through hole 21 ( Fig. 4d ), which can be used as a reference and abutment surface for the second hammer mandrel 12 during hammering of the housing 2 ( Fig. 4e ).
  • the housing hammers mandrel 12 After hammering the housing 2 on the housing hammer mandrel 12 - which can be carried out progressively in the direction of the arrow 23 ( Fig. 4e ) - the housing hammers mandrel 12 is removed and the undercut 7 for the locking of the closure head and the chamber 5 (if not yet in step Fig. 4c or Fig. 4d done) by machining, eg milling, manufactured ( Fig. 4f ). Subsequently, further openings, recesses or the like. are milled into the housing 2 to finalize this.
  • Fig. 5 shows a variant of the method of Fig. 4 in which a change of the hammer mandrels 11, 12 in the barrel hammer machine and the associated repositioning of the blank 20 is not required and thus all hammering steps for the barrel 1 and the housing 2 can be performed continuously in one go.
  • the in the Fig. 3a and 3b shown hammers mandrel arrangement 10 is used, in which the support rod 15 of the barrel hammer mandrel 11 is first passed through the bore 16 of the housing hammer mandrel 12 and in this constellation both hammers mandrels 11, 12 are inserted into the blank 20 ( Fig. 5a ).
  • the barrel hammer mandrel 11 is progressively advanced together with the forging hammers 22 with respect to the blank 20 in the direction of the arrow 23 (or the barrel 1 opposite to the arrow direction 23), the retaining bar 15 is pulled through the housing hammer mandrel 12 ( Fig. 5b ).
  • the barrel hemming mandrel 11 is at least partially retracted into the bore 16 of the housing hemming mandrel 12, ie at least with its tapered section 17 to center and axially align the entire hammer mandrel assembly 10 of first and second hammer mandrels 11, 12 ( Fig. 5c ).
  • the cartridge chamber part 14 of the barrel hammer mandrel 11 are retracted into the housing hemming mandrel 12, and optionally also the inner race profile part 13, ie the entire barrel hammers mandrel 11 (FIG. Fig. 5d ).
  • the flow of the blank material during hammering (cold forging) into the region 26 around the shoulder between the two hammer mandrels 11, 12 can be assisted by using a blank 20 which at this point has additional material 27 on its outer periphery has, for example, a circumferential bead.
  • this area 26 can also be post-machined again to form the undercut 7 and the defined inner shoulder 25 and, if appropriate, also to mill the chamber 5 this was not forged ( Fig. 5e ).
