Description

Technical Field

[0001] This utility model relates to the field of drug pressing tooling technology, and in particular to a safety screw plug drug pressing tooling. Background Technology

[0002] The propellant safety device, consisting of a safety plug and a delay charge, serves as part of the fuse isolation mechanism and plays a crucial role in disarming the fuse. When the projectile is fired, the recoil ignites the ignition mechanism, which in turn ignites the propellant safety device. This ignites the delay charge in the safety plug, initiating the delay-release process. When the projectile travels beyond the muzzle safety distance, the delay charge burns out, releasing the safety pin at its upper end, ending the delay-release process and releasing the second layer of restraint on the fuse. Therefore, during the propellant loading process, it is essential to ensure the quality of the propellant, the reliable ignition of the delay charge, and its strength to guarantee the reliability of the propellant safety device. However, traditional propellant loading methods are time-consuming and labor-intensive, resulting in a high scrap rate, low efficiency, and high costs for mass production. Utility Model Content

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please see Figures 1-7This utility model provides a safety plug injection tooling, including a sleeve 1, a punch 2, a die sleeve 3, a safety plug 4, a positioning post 5, a center pin 6, a needle sleeve 7, a flat-end set screw 8, a clutch seat 9, and a clutch cover 10. The center pin 6 is disposed in the needle sleeve 7. The clutch seat 9 is connected to the needle sleeve 7 through the flat-end set screw 8. The clutch cover 10 is disposed at the upper end of the clutch seat 9. The positioning post 5 is disposed at the top of the clutch cover 10 and sleeved on the upper end of the center pin 6. The die sleeve 3 is sleeved on the positioning post 5. The sleeve 1 is disposed at the top of the die sleeve 3. The punch 2 passes through the sleeve 1 and is connected to the positioning post 5 through the safety plug 4.

[0022] In one embodiment, the central needle 6 and the needle sleeve 7 are welded together by copper soldering to ensure that the central needle will not be pulled off under a certain amount of tension after welding.

[0023] In one embodiment, the clutch cover 10 and the positioning post 5 are riveted together. After riveting, the upper end face of the positioning post 5, i.e., the B face, must be horizontal to ensure that the medicine surface is horizontal when pressing the medicine.

[0024] In one embodiment, the clutch seat 9 is rotatably connected to the clutch cover 10.

[0025] In one embodiment, the dimensions of the positioning post 5, mold sleeve 3, clutch cover 10, sleeve 2, punch 1, and other parts can be adjusted according to requirements after assembly, making it suitable for pressing different amounts of propellant for various gunpowder safety devices and possessing adjustability. When the safety plug pressing tooling is in place, the A line of the center pin 6 is flush with the B surface of the positioning post 5, effectively ensuring the flatness of the bottom of the propellant surface of the safety plug 4.

[0026] In one embodiment, the clutch cover 10 and clutch seat 9 are configured such that, after assembly, the two inclined surfaces remain in close contact regardless of the angle to which they are rotated. After rotating in directions 01 and 02, the center pin 6 is unscrewed from the safety plug 4, allowing for mold release. This effectively saves time and manpower, improves efficiency, and is particularly suitable for mass production.

[0027] Specifically, the central needle 6 is placed in the needle sleeve 7 and brazed to ensure that the central needle 6 will not be pulled off under a certain amount of tension after welding. The needle sleeve 7 is placed in the hole of the clutch seat 9, and the flat-end set screw 8 is tightened. The positioning post 5 is riveted into the center hole of the clutch cover 10, passes through the central needle 6, and is placed so that the contact surfaces of the clutch cover 10 and the clutch seat 9 are in close contact. Then, it is rotated to the O1 direction. At this time, the A line of the central needle 6 should be flush with the B surface of the positioning post 5 to effectively ensure the flatness of the bottom of the medicine surface in the safety plug. The mold sleeve 3 is placed on the positioning post 5, and the safety plug and the sleeve 1 are placed in sequence in the hole of the mold sleeve 3. The weighed medicine is poured into the hole of the sleeve 1, and then the punch 2 is placed in the special pneumatic punch press to press the medicine.

[0028] Working Principle: In the small safety plug pressing fixture, after rotating the clutch cover and clutch seat to the pressing direction (01) shown in the diagram, insert the safety plug to be pressed through the center pin into the center hole of the die sleeve, adjusting its position to ensure the safety plug is horizontal. Insert the sleeve and pour the weighed powder into it, gently shaking the fixture to ensure even distribution of the powder. After inserting the punch into the sleeve, place the fixture under a dedicated pneumatic punch press for pressing. After pressing, rotate the clutch cover and clutch seat to the demolding direction (02) to demold. This fixture is suitable for pressing various amounts of gunpowder safety plugs. The fixture has a reasonable structure, integrating pressing and demolding operations, resulting in high efficiency and a fast production cycle. It saves time and labor, reduces costs, and is especially suitable for mass production on a production line.

[0029] This utility model's safety plug pressing fixture allows for integrated operation of pressing and unmolding by rotating the clutch cover and clutch seat in both directions (01 and 02). The fixture has a reasonable structure, high pressing efficiency, and is suitable for pressing various types of gunpowder safety plugs. It saves time and labor, reduces costs, and is particularly suitable for mass production on production lines.

[0030] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
