Description
Technical Field
The utility model relates to a small-bore ammunition is full plays assembly technical field specifically is a shell die lamella structure of stiching.
Background
The existing small-caliber shell full-elastic mouth-tightening die clack adopts two clacks and six clacks, the mode of the full-elastic mouth-tightening groove has two structures of a single groove and a double groove, the phenomenon of poor pull-out elastic force consistency exists in the pull-out elastic force test process after the shell is assembled with a mouth, particularly, the phenomenon of difficult combination of shells, poor pull-out elastic force consistency and the like exists in the shell with the two clack mouth-tightening die clack mouth, and because the problems existing in the assembly process of the shell directly influence the stability of the shell in the flying process and the hit probability to a target and put forward higher requirements on the assembly process of the shell, the problem of poor consistency of the full-elastic mouth is very important to solve.
Therefore, in order to improve the tightness consistency of the small-caliber cannonball, a new tightness mould section structure is needed in the full tightness mode.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to prior art, the utility model provides a shell mould lamella structure of holding a mouthful possesses the advantage that has fine uniformity when the full bullet assembly of small-bore shell is held a mouthful, has solved that the full bullet of current small-bore shell exists to pull out the elasticity uniformity relatively poor, close the thorax more difficult, hold a mouthful rear cartridge case and hold a mouthful position cracked problem appears easily in the transmission.
The utility model provides a following technical scheme: the utility model provides a shell die opening mould lamella structure, includes the mould lamella body, the side groove has been seted up to the side of mould lamella body, the side of mould lamella body is located the below in side groove and has seted up first open slot, the side of mould lamella body is located the below in first open slot and has seted up the second open slot, first raised groove has been seted up to the medial surface of mould lamella body, the medial surface of mould lamella body is located the below in first raised groove and has seted up the second raised groove, the oblique conical surface has been seted up to the medial surface of mould lamella body bottom.
Preferably, the number of the die section bodies is eight, and two side surfaces of the eight die section bodies are arranged adjacently.
Preferably, the length value of the side groove is greater than that of the first open groove, and the length value of the first open groove is greater than that of the second open groove.
Preferably, the outer side surface of the top of the mold half body is fixedly connected with a connecting bulge.
Compared with the prior art, the utility model discloses possess following beneficial effect:
1. this shell die flap structure that grips, the tight mouthful effect of this die flap body can be guaranteed through the cooperation in first protruding groove and second protruding groove, through the fillet that is equipped with on first protruding groove and the protruding groove of second, avoids shell to open a mouthful groove fracture in the process of launching.
2. This shell die flap structure that grips has corresponding oblique conical surface through die flap body bottom, makes things convenient for down the in-process under the die flap to avoid cartridge case shoulder conical surface, and cooperation through the side groove and first open slot and second open slot can be guaranteed that the cooperation between the die flap body is inseparabler.
Drawings
FIG. 1 is a front view of the present invention;
fig. 2 is a sectional view of the structure of the present invention.
In the figure: 1. a mold half body; 2. a side groove; 3. an oblique conical surface; 4. a first projection groove; 5. a second projection groove; 6. a second open slot; 7. a first opening groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, a shell mouth-tightening die piece structure comprises die piece bodies 1, the number of the die piece bodies 1 is eight, two side surfaces of the eight die piece bodies 1 are adjacently arranged, a connecting bulge is fixedly connected to the outer side surface of the top of the die piece body 1, the connecting bulge is beneficial to better fixing the die piece body 1 and a fixing mechanism on a punch press, a side groove 2 is formed in the side surface of the die piece body 1, a first open groove 7 is formed in the side surface of the die piece body 1, which is positioned below the side groove 2, a second open groove 6 is formed in the side surface of the die piece body 1, which is positioned below the first open groove 7, the length value of the side groove 2 is larger than that of the first open groove 7, the length value of the first open groove 7 is larger than that of the second open groove 6, and the matching between the die piece bodies 1 can be ensured to be tighter through the matching of the side groove 2 and the first open groove 7 and the second open groove, first protruding groove 4 has been seted up to the medial surface of mould lamella body 1, second protruding groove 5 has been seted up to the medial surface of mould lamella body 1 below that is located first protruding groove 4, the tight mouthful effect of this mould lamella body 1 can be guaranteed through the cooperation of first protruding groove 4 and second protruding groove 5, the fillet through being equipped with on first protruding groove 4 and the second protruding groove 5, avoid the shell to split in the tight mouthful of groove of launching process cartridge case, the oblique conical surface 3 has been seted up to the medial surface of mould lamella body 1 bottom, there is corresponding oblique conical surface 3 through mould lamella body 1 bottom, make things convenient for down the in-process under the mould lamella to avoid cartridge case shoulder conical surface.
