Description

Technical Field

[0001] The utility model belongs to the technical field of ammunition manufacturing, and particularly relates to a prefabricated fragment assembly tooling. Background Art

[0002] With the rapid development of the drone swarm technology, it is extremely urgent to counter the drone swarm. As one of the traditional short-range air defense means, the intensive interception by rapid-fire small-caliber anti-aircraft guns has the excellent characteristics of low cost, good effect and high cost-effectiveness. Therefore, a variety of ammunitions adopt the method of filling prefabricated fragments in the warhead. Through the scattering of the fragments, the strike target range is expanded, and area damage is caused to the drone swarm. The projectile loaded with prefabricated fragments can not only effectively cope with the threat of drone swarm attacks, but also improve the fire strike ability of the projectile against other defensive works, low-altitude targets, concealed and semi-concealed targets, and fully exert the damage effect of the projectile.

[0003] However, the prefabricated fragments are small in size and not easy to load. At present, the main methods for loading prefabricated fragments are to process the fragments into an integral form for loading, or to inject them into a whole for loading, etc. However, the number of fragments loaded by these methods is small, and machine processing is time-consuming and laborious, with low economic benefits. Summary of the Utility Model

[0004] To solve the problems raised in the above background art, the utility model provides a prefabricated fragment assembly tooling, which has the characteristics of being able to manually and quickly manufacture and shape a relatively large number of prefabricated fragments, saving time and processing costs.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a prefabricated fragment assembly tooling, including a sleeve. The sleeve is hollow inside and through at both ends. A number of slots are equidistantly arranged on both side walls. Support pieces are inserted into the slots. A shaping part is placed in the hollow part of the sleeve. The shaping part includes a base and a shaping column arranged at the axis of the base. The top of the shaping column extends out of the top of the hollow part of the sleeve. An installation component adapted to the shaping column is provided at the top of the sleeve. A positioning component is placed on the top of the installation component.

[0006] Preferably, the installation component includes two relatively arranged installation plates. Positioning grooves are respectively provided at the joints of the two installation plates, and they are adapted to the outer wall of the shaping column.

[0007] Preferably, the positioning component includes two clamping plates. Limiting grooves are respectively provided at the joints of the two clamping plates to form a circular through hole. The circular through hole and the bottom installation plate cooperate to form a placement cavity. A number of fragments are arranged in sequence in the placement cavity.

[0008] Preferably, at least two support pieces are inserted into a number of slots.

[0009] Preferably, the inside of the shaping column is hollow.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1-2 , the present utility model provides the following technical solutions: A prefabricated fragment assembly tooling, including a sleeve 6, the interior of the sleeve 6 is hollow and both ends are through. A plurality of slots 2 are equidistantly arranged on both side walls. Support plates 1 are inserted into the slots 2. A shaping member is placed in the hollow part of the sleeve 6. The shaping member includes a base 7 and a shaping column 5 arranged at the axis of the base 7. The top of the shaping column 5 extends out of the top of the hollow part of the sleeve 6. An installation component 3 adapted to the shaping column 5 is provided at the top of the sleeve 6. A positioning component 4 is placed on the top of the installation component 3.

[0017] Specifically, the installation component 3 includes two oppositely arranged installation plates. Positioning grooves 8 are respectively provided at the joints of the two installation plates, and they are adapted to the outer wall of the shaping column 5, and can be used to place fragments. At the same time, the fragments are placed around the shaping column 5 to form a certain regular shape.

[0018] Specifically, the positioning component 4 includes two clamping plates. Limiting grooves 9 are respectively provided at the joints of the two clamping plates to form a circular through hole. The circular through hole and the bottom installation plate cooperate to form a placement cavity. A plurality of fragments are arranged in sequence in the placement cavity, and the inner wall of the placement cavity limits the outer shape of the fragments.

[0019] Specifically, at least two support plates 1 are inserted into a plurality of slots 2, and the two support plates 1 ensure that the base 7 can be supported to descend in sequence.

[0020] Specifically, the shaping column 5 is hollow inside, which reduces the weight of the shaping column 5 itself, makes the tooling lightweight, and reduces the workload of the staff during use.

[0021] The working principle and usage process of the present utility model: For the prefabricated fragment assembly tooling described in the present utility model, when fragments need to be assembled, the shaping part is placed into the sleeve 6, and at the same time, the two support pieces 1 are sequentially placed into the slots 2 at the upper part of the sleeve 6. The uppermost support piece 1 supports the base 7 of the shaping part. Then, the placement assembly 3 and the positioning assembly 4 are sequentially placed at the opening at the top of the sleeve 6. After being assembled, the prefabricated fragments are poured into the placement cavity, and the prefabricated fragments are sorted out to make them positioned and shaped, so that the overall outer diameter circumference of a layer of prefabricated fragments is exactly the same as the outer diameter circumference of the base 7 (the outer diameter of the base 7 is the same as the inner diameter of the sleeve 6). Then, the positioning assembly 4 is fixed, and the placement assembly 3 is withdrawn from the top of the sleeve 6, so that the first layer of prefabricated fragments as a whole falls on the base 7. Then, the adhesive is applied to the upper surface of the fragments, and then the support piece 1 in the first layer of slot 2 is withdrawn, so that the base 7 is supported by the support piece 1 in the second layer of slot 2. Then, the above operations are repeated to make the second layer of fragments adhere to the first layer of fragments. In this way, the operation is repeated until the overall production of the fragments is completed. Then, the fragments are taken out from the sleeve 6, and thus the process is completed.

[0022] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
