[0002] In recent years, with the rapid development of my country's military science and technology, solid propellants, gunpowder, and related raw materials have been widely used in army, navy, and air force products. These products are flammable and explosive, and may ignite or explode due to impact, friction, or other factors during production, analysis, transportation, and use. Their safety performance directly affects the personal safety of production analysts, transportation personnel, and military users, as well as the safety of national property. Therefore, it is necessary to accurately measure the sensitivity to impact and friction using experimental devices to ensure product performance and provide strong data support for scientific research and production. After impact sensitivity testing, a guide ring and two impact pins containing hazardous materials are generated. Due to the risk of explosion or impact, these components are difficult to open, and the hazardous materials cannot be removed. If personnel forcibly open the assembly using pliers or other tools, the sample may explode due to compression, friction, and impact, endangering the personal safety of operators. Direct disposal of hazardous waste poses a significant safety hazard and does not meet safety requirements. Therefore, it is necessary to study methods for dismantling the assembly after impact sensitivity testing. Considering the characteristics of the assembly, a method for dismantling the assembly needs to be proposed, and a dismantling device capable of safely opening the guide ring and two impact pins containing hazardous materials needs to be developed.

[0019] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] The device for safely removing the guide ring and impact column assembly in this embodiment consists of a mold for removing the assembly, a hydraulic system, an extended air pipe (for safety), a pressure rod, and a steel bar.

[0021] Mold: The central hole has a diameter of 13mm to allow a 10mm diameter hammer to enter, but a 16mm diameter guide ring cannot enter. The outer diameter is 70mm, and the lower end has a 60mm diameter groove for placement on the hydraulic system.

[0022] Hydraulic System 1: It can provide very large forces gently and safely, ensuring personnel safety.

[0023] Extended hose 2: Due to the presence of residual propellant and other energetic products inside the assembly, a certain safety distance is required.

[0024] Pressure lever 3: It has a knob 5 on it, which can be tightened and loosened to maintain and release pressure.

[0025] Steel rod 4: 5mm in diameter and about 5cm in length, capable of pushing the striking post out from inside the guide ring.

[0026] Secondly, embodiments of this application provide a method for safely removing the guide ring and impact post assembly after an impact sensitivity test:

[0027] The assembly is placed vertically onto the mold and fitted onto the hydraulic system 1. The hydraulic system slowly lifts the column containing the assembly. The upper part of the device is designed as a protruding steel rod 4, with a cross-sectional area slightly smaller than that of the steel cylinder. When the loading device of the hydraulic system is pressed up, the surface of the protruding steel cylinder on the surface of the assembly comes into contact with the surface of the steel rod. With further pressure, the loading device rises, and the steel cylinder is continuously pushed into the groove of the loading device by the pressure of the steel rod above. Stop pressing, turn the knob to release the pressure, and remove the mold. The two steel cylinders that were pushed out of the guide ring can be seen. At this time, the two steel cylinders that are stuck together can be pried apart by hand, and the sample residue can be swept away with a brush.

[0028] Figure 6 A method for safely removing the guide ring and impact post assembly after an impact sensitivity test is shown.

[0029] Step 1: Place the assembly that has undergone the impact sensitivity test onto the mold.

[0030] Step 2: Place the mold on top of the hydraulic system of the disassembly device.

[0031] Step 3: Tighten the knob on the pressure lever clockwise, use the pressure lever to pressurize the hydraulic system, lift the mold until it contacts the steel bar, continue pressing, so that the steel bar gently pushes the impact pin out of the guide ring.

[0032] Step 4: Stop pressurizing, turn the knob on the pressurizing rod counterclockwise to release pressure, the mold will descend to its original position, remove the mold, take out the separated impact pin and guide ring, complete the disassembly of the assembly, and clean up the residual medicine in the middle.

[0033] This embodiment achieves a safe and gentle disassembly and assembly process, ensuring personnel safety, allowing for the reuse of test tool spare parts, and saving economic costs.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
