Description

The utility model relates to the field of equipment of ammunition, namely, to the initial and re-equipment of cartridge cases, in particular to the designs of press machines used to equip cartridges of hunting rifles.

Known technical solution according to patent RU 2103660 C1 F42B 33/02 publ. 01/27/1998, according to which the DEVICE FOR SEALING EQUIPPED CASES WITH "STAR", containing a base with a socket for the bottom of the sleeve, fixedly mounted on the base of the rod, a traverse with a supporting surface, movable relative to the rod and spring-loaded relative to it, a lever pivotally connected to the rod interacting with the traverse, forming the mandrel with working surfaces and sealing the matrix, characterized in that the traverse is stationary connected to the mandrel, and the matrix is installed inside the mandrel with the possibility of movement and t a spring loaded plunger, the axis of the mandrel, and the matrix nest under the bottom portion of the sleeve coincide and cam lever adapted to alternately interact with the supporting surface and the follower traverses matrix. The disadvantage is that the "asterisk" seal does not ensure the quality of the surface of the cartridge, and the formation of the "collar" of the sleeve is done manually and requires additional equipment.

Closest to the claimed is a technical solution according to the patent RU 116994 U1 F42B 33/10, publ. 06/10/2012, according to which the PRESS-MACHINE FOR EQUIPPING CARTRIDGES OF THE HUNTING GUNS contains a stand rigidly connected to it and placed on the working shelf perpendicular to its longitudinal axis, a clip mounted above the latter and spring-loaded relative to it in the axial direction, pivotally connected to the stand and a lever system and a nozzle mounted on the holder for inserting the capsule and filling with working material, a nozzle for preliminary shaping of the rolling of the cartridge in the form of a star and at least one nozzle for the end th star formation, a crimping sleeve designed to accommodate a cartridge in it, a closer of a predetermined position of the crimping sleeve on the working shelf in the form of a rotary relative to the last handle with a position lock and a socket for placing the crimping sleeve, eliminating its axial displacement when located on the working shelf, and fixed on the clip is a nozzle for pushing the equipped cartridge from the crimp sleeve. The press machine may additionally contain a nozzle mounted on a ferrule for crimping an equipped cartridge under the cone and a nozzle for removing the fired capsule and forming the spent sleeve. In the working shelf opposite each nozzle, grooves are made for periodic interaction with the handle position lock, and a through hole is additionally made in front of the nozzle for ejecting the equipped cartridge. In addition, an annular groove can be made on the outer surface of the crimp sleeve, and the socket has a corresponding protrusion designed to be placed in the annular groove when the crimp sleeve is located on the working shelf. The disadvantage of the prototype is that the termination of the "star" and the formation of the collar of the sleeve is done manually (by pressing the lever and rotation of the handle), which does not provide 100% repeatability of the termination and reduces the quality of the cartridges.

To eliminate these drawbacks, a press machine for equipping hunting rifle cartridges is proposed, which makes it possible to seal the cartridge case in two positions without changing the tool, unlike analogues and the prototype, where the “collar” of the cartridge is formed manually (rotation of the handle) in this device The “collar” of the sleeve is formed using an electric drive and provides 100% repeatability.

The device comprises a stand, on which a stand fixed, fixed by welding, on which the body, electric motor, gear; on the stand are mounting bowls for receiving shells. In the housing are spindles with matrices attached to them; while the axis of the spindles and mounting cups match. Toothed racks are cut on spindles; when the lever is pressed, the force is transmitted through the gear shaft to the spindles, while at the free end of one of the spindles there is a nut restricting the stroke of both spindles.

The sleeve, suitably prepared for embedment, is mounted on the installation bowl. When the lever is pressed, the spindles are lowered due to the rack and pinion gear, while the matrix is lowered onto the upper part of the sleeve and compresses it until it stops (to the limit nut). After closing, the lever is raised. Next, the sleeve is rearranged on the second installation bowl and press the lever all the way. In this case, the spindle performs translational and rotational movements simultaneously. Translational - carried out using a rack and pinion, and rotational due to the coaxial shaft on an angular contact bearing inside the spindle using an electric motor. After terminating the sleeve, the lever is raised.

The device can work under the right-left hand when moving the gear shaft.

The device can also perform the following operations: encapsulation, decapsulation, calibration of the sleeve base, calibration of the capsule socket, trimming the sleeve, chamfering the sleeve, straightening the deformed barrel of the sleeve, cutting the wad. Operations are performed by replacing the matrices with appropriate devices for their implementation.

The advantage of the claimed utility model in comparison with analogues: in all analogues and prototype the formation of the "collar" of the sleeve is done manually (rotation of the handle) or an additional device is required to compress the collar In the inventive device, the "collar" of the sleeve is formed using an electric drive (electric motor) and provides 100 % repeatability due to restrictive nut.

The technical result of the claimed utility model is to increase the quality of the cartridge and increase productivity due to the complete closure of the barrel of the cartridge case without changing the tool.

The technical result is achieved due to the design of a press machine for equipping hunting rifle cartridges, comprising a stand, a stand rigidly connected to the stand, a lever, mounting cups for receiving shells, characterized in that the housing, the electric motor, the gearbox are mounted on the stand, the mounting are mounted on the stand cups for receiving liners, spindles with matrices attached to them are placed in the housing; the axis of the spindles and mounting cups match; gear racks are cut on the spindles, a lever that transfers force to the spindles through the gear shaft, while at the free end of at least one spindle there is a nut restricting the stroke of at least two spindles. As a special case, the matrices for performing the operations are encapsulation, decapsulation, calibration of the sleeve base, calibration of the capsule socket, trimming the sleeve, chamfering the sleeve, straightening the deformed barrel of the sleeve, cutting the wad, are interchangeable devices.

An example implementation.

The press machine includes a stand 1 on which a stand 2 is fixed, fixed by welding. The casing 3, the electric motor 4, the gearbox 5 are fixed on the rack 2. The mounting bowls 6, 7 are placed on the stand 1. The spindles 8, 9 with the dies 10, 11 attached to them are mounted on the casing 3. The axes of the spindles 8, 9 and the mounting bowls 6 are 7 match. On spindles 8, 9, gear racks are cut. When you press the lever 12, the force is transmitted through the gear shaft 13 to the spindles 8, 9. At the free end of the spindle 8 there is a nut 14, restricting the stroke of the spindles 8, 9.

The device works as follows: The sleeve, prepared accordingly for sealing, is installed on the installation bowl 6. When the lever 12 is pressed, the spindles 8, 9 are lowered by a rack and pinion gear, while the matrix 10 is lowered onto the upper part of the sleeve and compresses it to the stop ( to limit nut 13). After closing, the lever 12 is raised. Next, the sleeve is rearranged on the installation bowl 7 and press the lever 12 until it stops. In this case, the spindle 9 performs translational and rotational movements simultaneously. Translational - is carried out using a rack and pinion, and rotational due to the coaxial shaft on an angular contact bearing inside the spindle 9 using an electric motor 4. After closing the sleeve, the lever 12 is raised.

The device can work under the right-left hand when shifting the gear shaft 13. The device can also perform the following operations: encapsulation, decapsulation, calibration of the sleeve base, calibration of the capsule socket, trimming the sleeve, removing the bevel of the sleeve, straightening the deformed sleeve of the sleeve, cutting wad. The operations are performed by replacing the matrices 10, 11 with interchangeable devices appropriate for their implementation.

The inventive utility model has an advantage over existing analogues. Unlike analogues, where the formation of the "collar" of the sleeve is made manually (rotation of the handle) in this device, the "collar" of the sleeve is formed using an electric drive (electric motor 4) and provides 100% repeatability due to the restrictive nut 14.

The machine is designed to equip cartridges with paper sleeves and plastic sleeves. Tests of the prototype confirmed the high quality and performance of the sealing of hunting casings.
