Description

Technical Field

[0001] This utility model relates to the field of ammunition production equipment technology, and in particular to a floating multi-shot linkage constant pressure press tool. Background Technology

[0002] Currently, projectile pressing typically uses hydraulic presses as the pressure source. However, hydraulic presses suffer from poor precision and significant pressure fluctuations. While these issues don't affect the pressing results for large-caliber projectiles, they have a substantial impact on small-caliber projectiles. Small-caliber projectiles don't require very high pressures; for example, a certain type of small-caliber projectile might require 20T of pressure. However, if only a 100T hydraulic press is available, and the pressure fluctuation of a 100T press is 5%, this is equivalent to exceeding the rated pressure by 25% for a small-caliber projectile, potentially posing a safety hazard.

[0003] The existing technology has at least the following problems: First, there is a mismatch between the projectile caliber and the hydraulic press. That is, when a large hydraulic press is used to press the explosive into a small-caliber projectile, the explosive may explode or the explosive in the same batch may be uneven, which may easily cause safety accidents. Second, small-caliber ammunition is produced in large batches. Pressing one round at a time will waste production time and result in low production efficiency. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by developing a floating, multi-shot, linkage-based constant-pressure propellant loading fixture. This invention can not only load multiple propellants in a single operation but also reduce propellant defects during the projectile loading process, effectively improving safety and efficiency.

[0005] The technical solution of this utility model to solve the technical problem is as follows: a floating multi-launch linkage constant pressure drug-pressing tooling includes a base, a number of cylinders are provided on the base, a pipeline is provided inside the base for connecting the number of cylinders, a piston rod is provided inside the cylinder, and a limiting protrusion is provided on the top of the piston rod.

[0006] As an optimization, the bottom of the cylinder is fixedly connected to the base with bolts. This ensures the connection strength between the cylinder and the base and reduces leakage.

[0007] As an optimization, the pipeline includes a horizontally arranged main pipe and several sets of vertically arranged branch pipes. One end of each branch pipe is connected to the main pipe, and the several sets of cylinders are connected to the other end of each branch pipe and the main pipe. By setting up the main pipe and branch pipes, installation space can be reserved, and the cylinders can be arranged reasonably.

[0008] As an optimization, the pipeline is arranged in a ring shape, with several sets of cylinders evenly distributed above the pipeline. By setting up a ring-shaped pipeline, installation space can be reserved, and the cylinders can be arranged in a reasonable manner.

[0009] As an optimization, a piston is located at the bottom of the piston rod, and hydraulic oil is contained in the cylinder and pipeline below the piston. By setting up the piston, pressure can be transmitted stably and friction with the cylinder can be reduced.

[0010] As an optimization, a handle is provided on the base. The handle makes it easier for workers to move the tooling.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting a base, the cylinder can be supported during propellant loading, ensuring the overall stability of the tooling. By setting several sets of cylinders and piston rods to form a single-acting hydraulic cylinder, a large hydraulic press can simultaneously load multiple sets of small-caliber projectiles, significantly improving work efficiency. By setting up pipelines, several sets of cylinders can be interconnected to form a communicating vessel, allowing pressure to be transmitted between them during loading, ensuring that each piston rod is subjected to the same pressure. When a large hydraulic press loads multiple sets of small-caliber projectiles, the pressure can be evenly distributed, reducing the impact of pressure fluctuations on loading. By setting a limiting protrusion, the projectile can be fixed in place during loading. This utility model can load multiple projectiles at once, reduce propellant defects during the loading process, effectively improve the safety of the projectile loading process, and increase loading efficiency.

[0015] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0016] Example 1 Figures 1 to 2 As one embodiment of this utility model, such as Figures 1 to 2 As shown, a floating multi-launch linkage constant pressure drug-pressing fixture includes a base 1, five sets of cylinders 2 on the base 1, a pipe 3 inside the base 1 for connecting the five sets of cylinders 2, a piston rod 4 inside the cylinder 2, and a limiting protrusion 5 on the top of the piston rod 4.

[0017] By setting the base 1, the cylinder 2 can be supported during the pressing process, ensuring the overall stability of the tooling. By setting several sets of cylinders 2 and piston rods 4, a single-acting hydraulic cylinder is formed, which allows a large hydraulic press to simultaneously press multiple sets of small-caliber projectiles, greatly improving work efficiency. By setting the pipeline 3, several sets of cylinders 2 can be interconnected to form a communicating vessel, allowing pressure to be transmitted between them during the pressing process, so that each piston rod 4 is subjected to the same pressure. When a large hydraulic press presses multiple sets of small-caliber projectiles, the pressure can be evenly distributed, reducing the impact of pressure fluctuations on the pressing process. By setting the limiting protrusion 5, the projectile can be fixed for pressing.

[0018] The bottom of the cylinder 2 is fixedly connected to the base 1 by bolts 6, and a sealing gasket or sealing ring is provided at the connection. This ensures the connection strength between the cylinder 2 and the base 1 and reduces leakage.

[0019] The pipeline 3 is arranged in an I-shape, including a set of horizontally arranged main pipes 7 and four sets of vertically arranged branch pipes 8. One end of the branch pipe 8 is connected to the main pipe 7, and the four sets of cylinders 2 are respectively connected to the other end of the branch pipes 8. One set of cylinders 2 is connected to the center of the main pipe 7. By setting the main pipe 7 and branch pipes 8, installation space can be reserved and the cylinders 2 can be arranged reasonably.

[0020] A piston is located at the bottom of the piston rod 4, and hydraulic oil is contained in the cylinder 2 and pipeline 3 below the piston. By setting up the piston, pressure can be transmitted stably and friction with the cylinder 2 can be reduced.

[0021] The base 1 is equipped with a handle 9. The handle 9 makes it easy for workers to move the tooling.

[0022] Example 2 The difference between this and the first embodiment is that the pipe 3 is annular, and the five sets of cylinders 2 are evenly arranged above the pipe 3. By setting the pipe 3 in an annular shape, installation space can be reserved, and the cylinders 2 can be arranged reasonably.

[0023] During the loading process, the loading fixture is placed below the hydraulic press. JHL-2 blunt black aluminum explosive is selected, and the projectile is loaded using a pre-loaded explosive column method. The loaded explosive density is greater than 1.86 g / cm³. The projectile is filled with pre-loaded explosive columns. The punch is pre-placed inside the projectile and placed on the piston rod 4 along with the projectile. The limiting protrusions 5 at the top of the five sets of piston rods 4 are connected to the bottom of the five sets of projectiles respectively, thereby fixing the position of the projectile. The hydraulic press is started to apply pressure to the punch. When the five sets of punches press down to load the projectile, the piston rods 4 support the projectile. The pressure on the piston rods 4 is distributed and balanced by the hydraulic oil in the pipeline 3, so that the five sets of piston rods 4 are subjected to the same pressure, thereby subjecting the explosive column inside the projectile to the same pressure, completing the loading process. After loading, no defects were found in the loading after flaw detection. The explosive loading density can reach 96.7% of the theoretical density. This invention can both deliver multiple propellant charges in a single burst and reduce propellant defects during the propellant loading process, effectively improving safety and efficiency.
