In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] The utility model discloses a cutting device for safely cutting explosives. Figure 1-9 As shown, it includes: a cutting frame 1 arranged in a frame structure, a cutting table 2 is installed on the cutting frame 1, a cutting lower knife 3 is installed in the cutting table 2, an upper cutting knife 4 is slidably connected in the cutting table 2 and abuts against the lower cutting knife 3, a cutting hole 31 is provided through the lower cutting knife 3, and the cutting hole 31 is used to accommodate the passage of pyrotechnics, the upper cutting knife 4 and the lower cutting knife 3 are made of ceramic material, and a driving member 5 for driving the upper cutting knife 4 to slide in the cutting table 2 is installed on the cutting frame 1, so that the upper cutting knife 4 and the lower cutting knife 3 can safely cut the pyrotechnics. In the specific implementation process, the pyrotechnics can be detonating cords, etc.

[0031] It should be noted that the upper cutting knife 4 is driven by the driving member 5 to slide in the cutting table 2, and the upper cutting knife 4 and the lower cutting knife 3 are used to safely cut pyrotechnics, thereby providing a cutting device for safely cutting pyrotechnics. Since the upper cutting knife 4 and the lower cutting knife 3 are made of ceramic material, sparks are prevented when cutting pyrotechnics, thereby achieving safe cutting of pyrotechnics.

[0032] like Figure 1-5 As shown, the driving member 5 is a driving cylinder, and the telescopic rod of the driving cylinder is fixedly connected to the cutting upper knife 4.

[0033] like Figure 1-5 As shown, it also includes an elastic pressing assembly 6, which is used to adjust the pressing force between the lower cutting knife 3 and the upper cutting knife 4. It should be noted that, through the setting of the elastic pressing assembly 6, a certain pressing force is provided to the lower cutting knife 3, and when the impact force during cutting is greater than the pressing force, the lower cutting knife 3 can be retreated to prevent the lower cutting knife 3 from being broken by the impact force.

[0034] like Figure 1-5As shown, there are two elastic pressing assemblies 6, and the two elastic pressing assemblies 6 are arranged adjacent to each other. It should be noted that there are two elastic pressing assemblies 6, which is convenient for adjusting the pressing force of the opposite ends of the cutting lower knife 3.

[0035] like Figure 3-5 As shown, the elastic crimping assembly 6 includes a crimping seat 61 installed on one side of the cutting table 2, the crimping seat 61 is threadedly connected with a screw 62, the end of the screw 62 is abutted with a crimping block 63 and a crimping spring 64 in sequence, the crimping block 63 is located in the crimping seat 61, and the crimping spring 64 abuts against the cutting lower knife 3. In the specific implementation process, the crimping spring 64 is in a compressed state;

[0036] When the upper cutting knife 4 cuts pyrotechnic products, the impact force is greater than the elastic force of the crimping spring 64, and the lower cutting knife 3 squeezes the crimping spring 64 to further contract, preventing the lower cutting knife 3 from being shattered by the impact force; the screw 62 is embedded in the crimping seat 61 and abuts against the crimping block 63. By adjusting the depth of the screw 62 embedded in the crimping seat 61, the compression degree of the crimping spring 64 is adjusted, thereby adjusting the clamping force between the lower cutting knife 3 and the upper cutting knife 4.

[0037] like Figure 3-5 As shown, the screw rod 62 is threadedly connected with a nut 65 located on one side of the crimping seat 61. It should be noted that the screw rod 62 can be prevented from loosening by the arrangement of the nut 65.

[0038] like Figure 3-7 As shown, the cutting table 2 includes a first cutting seat 21 and a second cutting seat 22 that are detachably connected, the first cutting seat 21 is provided with a receiving groove 211 for accommodating the lower cutting knife 3, and the second cutting seat 22 is slidably connected to the upper cutting knife 4. In the specific implementation process, a through hole 212 corresponding to the cutting hole 31 is provided in the first cutting seat 21, one end of the crimping spring 64 is embedded in the crimping seat 61, and the other end of the crimping spring 64 is embedded in the first cutting seat 21 and abuts against the lower cutting knife 3.

[0039] like Figure 3-7 As shown, the second cutting seat 22 is provided with a slide groove 221 that slidably cooperates with the cutting upper knife 4, and the slide groove 221 is connected with two opposite end surfaces of the second cutting seat 22. It should be noted that the sliding setting facilitates the cutting upper knife 4 to slide in the cutting table 2.

[0040] Working principle: The upper cutting knife 4 is driven by the driving member 5 to slide in the cutting table 2. The upper cutting knife 4 and the lower cutting knife 3 are used to safely cut pyrotechnics, thereby providing a cutting device for safely cutting pyrotechnics. Since the upper cutting knife 4 and the lower cutting knife 3 are made of ceramic material, sparks are prevented when cutting pyrotechnics, thereby achieving safe cutting of pyrotechnics.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
