[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0029] The embodiment of the present application provides a circumferential shaped charge pipe cutting device, which can solve the problems of uneven cutting seams and poor accuracy of the shaped charge pipes processed by the cutting device in the related art.

[0030] See Figures 1 to 4, an embodiment of the present application provides a circumferential energy - concentrating tube cutting device, which includes: a fixing component 1, a cutting component 3, a plurality of pushing components 2 and a numerical control device. The fixing component 1 is used to fix the energy - concentrating tube; the plurality of pushing components 2 are installed on the fixing component 1 along the circumferential direction of the energy - concentrating tube, and a cutting component 3 is installed on each pushing component 2, and the pushing component 2 is used to drive the cutting component 3 to move along the radial direction of the energy - concentrating tube; the numerical control device is electrically connected to the pushing component 2 and the cutting component 3, and the numerical control device is used to control the operation of the pushing component 2 and control the cutting component 3 to cut the energy - concentrating tube.

[0031] In the present application, different - diameter energy - concentrating tubes can be fixed through the fixing component 1, so that the device meets the preparation requirements of energy - concentrating tubes of various specifications. By controlling the operation of the cutting component 3 through the numerical control device, it replaces the cutting method of manually holding a cutting machine. Before cutting, the cutting component 3 is accurately aligned with the circumferential energy - concentrating tube, and during cutting, the numerical control device can control the cutting - seam depth, cut - surface flatness, etc. of the cutting component 3, ensuring the accuracy requirements of cutting, and at the same time, it can also avoid the situation that the cut - seams of the processed energy - concentrating tubes are uneven.

[0032] It should be noted that in some possible embodiments, one fixing component 1 can be provided. Through this one fixing component 1, the energy - concentrating tube is fixed. After one cut - seam of the energy - concentrating tube is processed, the installation position of the energy - concentrating tube is adjusted so that the cutting component 3 processes another cut - seam of the energy - concentrating tube until all the cut - seams on the energy - concentrating tube are processed;

[0033] In some other possible embodiments, a plurality of fixing components 1 are provided. Compared with the setting method where there is only one fixing component 1, when a plurality of fixing components 1 are provided, the processing efficiency of the energy concentrating tube can be improved. The plurality of fixing components 1 are coaxially and spaced apart along the axial direction of the energy concentrating tube, so that when the energy concentrating tube is processed, it can be connected to the plurality of fixing components 1 simultaneously, and the cutting component 3 can simultaneously process cutting slits at different positions on the energy concentrating tube. On this basis, it is set that two adjacent fixing components 1 are connected by a connecting rod 4. Specifically, the connecting rod 4 is connected to the pushing component 2. Since a number of pushing components 2 are installed on one fixing component 1, in this embodiment, the installation position of the connecting rod 4 can be determined according to the actual situation. To illustrate this embodiment more clearly, the following is an example: For example, four fixing components 1 are provided, namely the first fixing component, the second fixing component, the third fixing component, and the fourth fixing component. Three pushing components 2 are provided on each fixing component 1. These three pushing components 2 are named pushing component a, pushing component b, and pushing component c. Three connecting rods 4 are provided and named the first connecting rod, the second connecting rod, and the third connecting rod. The pushing component a on the first fixing component is connected to the pushing component a on the second fixing component through the first connecting rod, the pushing component b on the second fixing component is connected to the pushing component b on the third fixing component through the second connecting rod, and the pushing component c on the third fixing component is connected to the pushing component c on the fourth fixing component through the third connecting rod. The energy concentrating tube is connected to the first fixing component, the second fixing component, the third fixing component, and the fourth fixing component, and the cutting component 3 is installed on the first connecting rod 4, the second connecting rod 4, and the third connecting rod 4. When the pushing component a, the pushing component b, and the pushing component c work, they drive the cutting component 3 to cut different positions of the energy concentrating tube. In this embodiment, the connecting rod 4 is detachably connected to the pushing component 2 through a fastener 35. For example, a connection hole is provided on the pushing component 2, a threaded groove is provided at one end of the connecting rod 4, the fastener 35 is a nut, and after the connecting rod 4 passes through the connection hole, the nut locks and fixes one end of the connecting rod 4 to the pushing component 2.

[0034] In some other embodiments, a plurality of fixing components 1 are provided and the fixing components 1 are connected by a connecting rod 4. Specifically, a number of pushing components 2 are provided on one fixing component 1. In this embodiment, the number of connecting rods 4 is the same as the number of pushing components 2 on one fixing component 1. The plurality of fixing components 1 are coaxially and spaced apart along the axial direction of the energy concentrating tube, and the pushing components 2 on each fixing component 1 correspond to each other. To illustrate this embodiment more clearly, the following is an example: For example, as Figure 1As shown in the figure, three pushing components 2 are arranged on a fixed component 1. These three pushing components 2 are named pushing component a, pushing component b, and pushing component c. Three connecting rods 4 are provided and named the first connecting rod, the second connecting rod, and the third connecting rod. Multiple pushing components a are connected to each other through the first connecting rod, multiple pushing components b are connected to each other through the second connecting rod, and multiple pushing components c are connected to each other through the third connecting rod. A plurality of cutting components 3 are arranged on each connecting rod 4, and each cutting component 3 is arranged between two adjacent fixed components 1.

[0035] On the basis of the above embodiment, in this embodiment, the fixed component 1 includes a pipe body fixing member 11 and a plurality of locking members 12. A channel 113 for the energy-gathering pipe to pass through is opened in the center of the pipe body fixing member 11. The locking members 12 are movably installed on the pipe body fixing member 11 along the circumferential direction of the energy-gathering pipe. One end of the locking member 12 extends into the channel 113 and is used to radially abut or release the energy-gathering pipe along the channel 113.

[0036] In this embodiment, since the locking members 12 can move on the pipe body fixing member 11, a plurality of locking members 12 can cooperate to fix energy-gathering pipes with different diameters.

[0037] In this embodiment, the pipe body fixing member 11 includes an outer ring 110 and an inner ring 112. The inner ring 112 is connected to the middle of the outer ring 110 and is coaxially arranged with the outer ring 110. A channel 113 for the energy-gathering pipe to pass through is opened in the center of the inner ring 112. In some embodiments, the inner ring 112 and the outer ring 110 are connected by fixing rods; in other embodiments, a pushing component 2 is installed between the inner ring 112 and the outer ring 110, and the inner ring 112 and the outer ring 110 are connected through the pushing component 2. At this time, the locking member 12 can be set as a screw rod, and the screw rod is threadedly connected to the inner ring 112, so that one end of the screw rod penetrates the inner wall of the inner ring 112 and extends into the inside of the channel 113. When the energy-gathering pipe needs to be fixed, first pass the energy-gathering pipe through the inside of the channel 113, and then rotate the screw rod so that the screw rod radially abuts the energy-gathering pipe along the channel 113. The smaller the diameter of the energy-gathering pipe, the closer the screw rod is to the central axis of the channel 113 after abutting the energy-gathering pipe.

[0038] Based on the above embodiments, in this embodiment, the pushing component 2 includes: a guide rail 21, a push rod 23, and a driving mechanism. The guide rail 21 is installed on the fixing component 1; the push rod 23 is slidably disposed on the guide rail 21, and a cutting component 3 is installed thereon; the driving mechanism is connected to the push rod 23 and the numerical control device. In this embodiment, the guide rail 21 is installed between the inner ring 112 and the outer ring 110, and the extension line of the guide rail 21 passes through the center of the inner ring 112. The driving mechanism can be installed on the fixing component 1 or inside the guide rail 21. It needs to be connected to the push rod 23 and, under the control of the numerical control device, drives the push rod 23 to move and controls the stroke size of the push rod 23, which can provide a quantitative displacement stroke for the push rod 23 and also provide a side pressure for the cutting component 3 to cut the shaped charge tube, meeting the requirements for different cut depths.

[0039] As Figure 1 shown, when there are multiple pipe body fixing members 11, on the same horizontal line, multiple guide rails 21 are connected by the same connecting rod 4. At this time, the multiple push rods 23 connected to the same connecting rod 4 move simultaneously and stop simultaneously, and the stroke sizes of the multiple push rods 23 are also the same. To facilitate the connection between the connecting rod 4 and the push rod 23, a connection ring 22 is fixed at one end of the push rod 23, so that the connection ring 22 can slide inside the guide rail 21 under the push of the push rod 23. The same connecting rod 4 passes through the connection rings 22 on each fixing component 1, that is, the same connecting rod 4 passes through the connection rings 22 on each fixing component 1 arranged coaxially. After the connecting rod 4 passes through, fasteners 35 are installed at both ends of the connecting rod 4 to fix the connecting rod 4 to the pushing component 2. The cutting component 3 is installed on the connecting rod 4 and is located between two adjacent pipe body fixing members 11. When the cutting component 3 is working, the connecting rod 4 itself does not rotate, ensuring the stability of the cutting component 3 during the cutting process.

[0040] Among them, the cutting assembly 3 includes a brushless motor 31 and a cutter 33. The brushless motor 31 is connected to the pushing assembly 2. The extending direction of the output shaft of the brushless motor 31 is parallel to the axial direction of the channel 113. The brushless motor 31 is electrically connected to the numerical control equipment through a wire 32. The cutter 33 is detachably connected to the output shaft of the brushless motor 31. The connecting rod 4 is formed by connecting multiple connecting rods. The length of the connecting rod 4 is determined according to the length of the shaped charge tube to be processed, the number of cut slots, the width of the cut slots, the spacing between the cut slots, etc. When the cutting assembly 3 is connected to the connecting rod 4, one end of the connecting rod passes through a connecting ring 22 and is connected to the previous brushless motor 31, and the other end passes through another connecting ring 22 and is connected to the next brushless motor 31. A cutter 33 is installed on one side of the brushless motor 31, so that the cutter 33 is fixed to the brushless motor 31 by a screw 34. At this time, the cutter 33 is sleeved on the outer peripheral surface of the connecting rod. After the brushless motor 31, the cutter 33 and the connecting rod 4 are installed, the connecting rod 4 is fixed to the connecting ring 22 by using a fastener 35. Specifically, locking nuts are threadedly connected to both ends of the connecting rod 4 and are abutted against the guide rail 21 on the outermost tube fixing member 11. According to different situations, circular cutters 33 with different thicknesses and different diameters can be selected. The side edge of the cutter 33 is sharp, and shaped charge tubes of different specifications can be cut. The rotation speed, torque, and power of the brushless motor 31 are uniformly controlled by the numerical control equipment, so as to provide power for the cutter 33 to cut.

[0041] On the basis of the above embodiments, in this embodiment, the fixing assembly 1 further includes a base 10. The tube fixing member 11 is detachably connected to the base 10, and scale marks are provided on the base 10. The base 10 includes a base 100, a slide rail 101, and a clamping table 102. The slide rail 101 is fixed to the top end of the base 100. One or more slide rails 101 can be arranged according to the actual situation. A plurality of clamping tables 102 are slidably connected to each slide rail 101. The clamping table 102 is detachably connected to the tube fixing member 11. Specifically, a mounting rod 111 is fixedly installed on the surface of the outer ring 110. When the tube fixing member 11 is installed on the base 10, the clamping table 102 is used to clamp and fix the mounting rod 111. Scale marks are provided on the slide rail 101. When there is one tube fixing member 11, when adjusting the position of the shaped charge tube, the displacement amount of the shaped charge tube can be determined according to the scale marks. When there are multiple tube fixing members 11, the distance between adjacent two tube fixing members 11 and the setting position of the cutter 33 can be determined according to the scale marks. Since the clamping table 102 can slide relative to the slide rail 101, the position of the clamping table 102 can be adjusted at any time according to the actual situation. After the position of the clamping table 102 is determined, the clamping table 102 is temporarily fixed to the slide rail 101 to improve the stability of the device during the processing of the shaped charge tube.

[0042] Before preparing the shaped charge tube, the required slit spacing and the required slit width should be confirmed. Accordingly, the length of the connecting rod 4 and the size of the cutting tool 33 are selected. For example, if a shaped charge tube with a slit spacing of 4 cm and a slit width of 3 mm needs to be prepared, then a cutting tool 33 with a thickness of 3 mm needs to be selected, and the length of the connecting rod 4 should be an integer multiple of the slit spacing, such as 8 cm. Then, the staff first adjusts the position of the tube fixing member 11 on the base 10 according to the required slit spacing, and fixes the base 10 and the tube fixing member 11. Then, the cutting assembly 3 is installed on the connecting rod 4, and the connecting rod 4 with the cutting assembly 3 installed is connected to the pushing assembly 2. After assembling the tube fixing member 11, the base 10, the pushing assembly 2 and the cutting assembly 3, then the stroke size of the push rod 23 and the rotation speed size of the brushless motor 31 are set through the numerical control device. Subsequently, the numerical control device is started for dry-run debugging to observe whether the entire device operates stably. This mainly includes observing whether the connecting ring 22 in the guide rail 21 can slide normally in the guide rail 21, whether the connecting rod 4 shows abnormal buckling due to inconsistent stroke of the push rod 23, and whether the cutting tool 33 is firmly connected to the brushless motor 31 and the connecting rod 4 is firmly connected to the brushless motor 31, etc. After confirming the stability of the device, the locking member 12 on the inner ring 112 should be unscrewed, the shaped charge tube to be cut is placed in, the shaped charge tube is positioned through the scale marks on the slide rail 101, and then the locking member 12 is tightened. The driving mechanism and the brushless motor 31 are started through the numerical control device. When the shaped charge tube is cut, each push rod 23 undergoes an equal displacement in the guide rail 21, driving the connecting rod 4 to generate an equal displacement together. The brushless motor 31 drives the cutting tool 33 to rotate at a high speed together, and is driven by the connecting rod 4 to generate an equal displacement and thus continuously approach the shaped charge tube to be cut. When the displacement stroke of the push rod 23 ends, one cutting of the shaped charge tube is correspondingly completed. If multiple cuts are required, the push rod 23 should first be controlled to return to its original position, then the locking member 12 on the inner ring 112 is loosened, the position of the shaped charge tube is adjusted, and then the above cutting process is repeated. After all cutting tasks are completed, the brushless motor 31 should be turned off first, and then the push rod 23 should be controlled to return to its original position to prevent secondary injuries. After the production work of this time is completed, the waste chips generated during the cutting process are removed after removing the cutting assembly 3, the vice bench 102, etc., and then cleaned by the staff. It is strictly prohibited to handle the waste chips during the cutting process of the shaped charge tube.

[0043] Through the above technical solutions, the cutting device can have good reconstructability and high modularity, enabling it to be flexibly erected at the construction site and endowing the entire device with the ability to produce shaped charges of various specifications; it can accurately position the cutter 33 and the shaped charge, thus achieving high-precision and high-efficiency processing of the shaped charge; by controlling the distance between the clamping tables 102, the thickness of the cutter 33, the length of the connecting rod 4, the dimensions of the inner ring 112 and the outer ring 110, etc., the cutting device can control the slit spacing, slit width, etc. of the shaped charge, so as to be able to produce shaped charges of various different specifications; also, through the integrated numerical control system, the staff only needs to simply control the stroke of the ejector rod 23 to complete the production task of the shaped charge, featuring simple operation.
