Description

Technical Field

[0001] The utility model relates to the technical field of combined response components, in particular to a device combining a projectile and a cartridge. Background Art

[0002] The projectile is the part of the shell including the fuze that directly completes the combat mission, that is, the warhead of the shell, which is composed of the fuze, shell body, belt, filling, stabilization device (using tail-stabilized projectile), etc. Due to the company's key bidding project that requires the projectile to be pressed into the cartridge, the time is tight and the task is heavy, and it is necessary to design a device that combines the projectile and the cartridge to meet the test needs of the scientific research stage. The existing device cannot adjust and position the combination position well, and it is difficult to meet the requirements of the drawings. Utility Model Content

[0003] In view of this, the utility model provides a device for combining a projectile and a cartridge, which can adjust the combined position of the projectile and the cartridge and has a positioning function to meet the requirements of the drawings.

[0004] The technical solution is: a device combining a projectile and a cartridge, comprising a tight die base, a tight die, a guide column, a pressure plate, a spring, a locking bolt, a cartridge, a rear lifting plate, a rear baffle and a projectile body. The upper part of the tight die base is provided with two threads, a tight die is provided on one side of the upper part of the tight die base, the upper part of the tight die is slidably connected with a guide column, another tight die is provided on the upper part of the guide column, a pressure plate is provided on the upper part of the other tight die, threads are provided on both sides of the pressure plate, two springs are connected between the pressure plate and the tight die base, the two springs are symmetrically arranged, locking bolts are connected to both sides of the pressure plate through threads, the spring is sleeved on the locking bolts, the other ends of the two locking bolts are threadedly connected to the tight die base, a cartridge is placed between the two tight dies, the cartridge is horizontally arranged, a rear lifting plate is placed on the side of the tight die base away from the spring, the rear lifting plate contacts the cartridge, a rear baffle is clamped on the side of the tight die base away from the spring, the rear baffle contacts the rear lifting plate, the rear baffle contacts the cartridge, and a projectile body is placed on one side of the cartridge.

[0005] The beneficial effects are: 1. The rear lifting plate can be adjusted to a suitable combination position;

[0006] 2. Simple operation. After the mold is adjusted for the first time, just put the projectile and the cartridge into the mold to realize the combination function;

[0007] 3. The mold has both positioning and combining functions, meeting the requirements of the drawings;

[0008] 4. The parts of the mold are simple to process and low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0014] Embodiment 1: A device combining a projectile and a cartridge, such as Figure 1-Figure 3 As shown, it includes a tight die base, a tight die, a guide column, a pressure plate, a spring, a locking bolt, a cartridge, a rear lifting plate, a rear baffle and a projectile. The upper part of the tight die base is provided with two threads, a tight die is provided on one side of the upper part of the tight die base, the upper part of the tight die is slidably connected with a guide column, another tight die is provided on the upper part of the guide column, and a pressure plate is provided on the upper part of the other tight die. Threads are provided on both sides of the pressure plate, two springs are connected between the pressure plate and the tight die base, the two springs are symmetrically arranged, locking bolts are connected to both sides of the pressure plate through threads, the springs are sleeved on the locking bolts, and the other ends of the two locking bolts are threadedly connected to the tight die base, a cartridge is placed between the two tight dies, the cartridge is horizontally arranged, a rear lifting plate is placed on the side of the tight die base away from the spring, the rear lifting plate contacts the cartridge, a rear baffle is clamped on the side of the tight die base away from the spring, the rear baffle contacts the rear lifting plate, the rear baffle contacts the cartridge, and a projectile is placed on one side of the cartridge.

[0015] The use steps of the utility model are as follows: Step 1: placing the tight-mouth mold in a press;

[0016] Step 2: Place the projectile body and cartridge in the tight-mouth die, and adjust the position of the rear lift plate and rear baffle plate to ensure that the joint is in the position required by the drawing;
