The pipe positioning tooling 100 is used to fix the pipe 500 to ensure its stability during the punching process; the punching module 200 is used to perform punching operations on the pipe 500; and the pipe feeding mechanism 300 is responsible for automatically feeding the pipe 500 into the pipe positioning tooling 100 to realize automated operation.

[0025] The specific embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. 1. Pipe positioning tool 100

[0026] The pipe positioning tool 100 includes a first fixing mechanism 110 , a second fixing mechanism 140 , a third fixing mechanism 130 and a supporting core rod 120 .

[0027] The first fixing mechanism 110: includes a first positioning block 111 and a locking nut 112. The first positioning block 111 is provided with a core rod hole for receiving one end of the support core rod 120. The locking nut 112 is used to fix the support core rod 120. The fixing position C2 of the locking nut 112 is preferably slightly below the center C1 of the support core rod 120, such as less than 2-10 mm, so that an upward pressure force can be formed on the support core rod 120 to ensure the stability of the support core rod 120. An elastic gasket 113 can be arranged between the locking nut 112 and the first positioning block 111 to increase elastic buffering and improve the locking effect. The first positioning block 111 and the frame 400 are connected by bolts or other fasteners to ensure the stability of the structure while also facilitating disassembly.

[0028] The second fixing mechanism includes a second positioning block 140, which is provided with a through receiving hole 142 for inserting the supporting core rod 120 and the pipe 500. A first punch hole 141 is provided on one side or both symmetrical sides of the receiving hole 142, and the first punch hole 141 is connected to the receiving hole 142 for inserting the punch 220 to achieve the punching operation. The second positioning block 140 is also provided with a chip discharge groove 143 that opens downward and is connected to the first punch hole 141, which is used to discharge the waste generated during the punching process. A waste hole 410 is provided below the corresponding chip discharge groove 143 on the frame 400, and a waste collection box can be further arranged below the waste hole 410 to collect waste and keep the working environment clean. When the first punch holes 141 are opened on both sides of the accommodating hole 142, punching operations can be performed on both sides of the pipe fitting 500 at the same time. When the first punch hole 141 is opened on only one side of the accommodating hole 142, punching operations can be performed on one side of the pipe fitting 500. The accessories are selected and installed according to actual needs.

[0029] The third fixing mechanism 150: The third fixing mechanism 150 may be a mechanical clamping device, such as a chuck structure, used to fix the pipe 500 after the pipe 500 is pushed into the receiving hole 142; or, in some embodiments, the third fixing mechanism 150 may also include a movable clamping block and a third driving member for driving the clamping block to move, and the third driving member may be a cylinder or an electric push rod. After the pipe 500 is pushed into the receiving hole 142, the third driving member drives the clamping block to close and fix the pipe 500 to ensure its stability during the punching process.

[0030] Support core rod 120: Its outer diameter is slightly smaller than the inner diameter of the pipe 500, and it is a solid piece, used to provide sufficient support force to the pipe 500 during the punching operation to prevent the pipe 500 from being deformed due to extrusion. One end of the support core rod 120 is fixed to the first positioning block 111 of the first fixing mechanism 110, and the other end extends into the accommodating hole 142 of the second fixing mechanism to provide internal support for the pipe 500 to prevent the pipe 500 from being flattened or deformed during the punching process. The outer diameter of the support core rod 120 can be slightly smaller than the inner diameter of the pipe 500 to facilitate the installation of the pipe 500, but it cannot be too small, otherwise it cannot provide sufficient support. In this embodiment, the outer diameter of the support core rod 120 is designed to be 0.5-5mm smaller than the inner diameter of the pipe 500. Please refer to Figure 5-Figure 6 The second punch hole 121 and the chip removal hole 122 connected to the second punch hole 121 are provided at the position corresponding to the first punch hole 141 on the support core rod 120, so as to facilitate the insertion of the punch 220 and realize chip removal. The chip removal hole 122 is connected to the chip removal groove 143 on the second fixed block 140 to realize the discharge of waste chips. In order to facilitate processing and observation, the chip removal hole 122 is designed as a through hole. The position corresponding to the chip removal hole 122 on the second fixed block 140 is provided with an observation window 141. The operator can observe the chip removal through the observation window 141 during the punching operation to avoid abnormal situations such as blockage. In addition, in order to facilitate the insertion of the pipe fitting 500, the end of the support core rod 120 close to the pipe fitting 500 is designed as a gradually transitioning tapered structure 123, and the tapered structure 123 extends outside the receiving hole 142. 2. Punching module 200

[0031] Each group of punching modules 200 includes a punch 220 and a first driving member 210, and the first driving member 210 can be a cylinder or an electric push rod. Multiple groups of punching modules 200 are arranged at intervals along the length direction of the second positioning block 140, and each punching module 200 is arranged corresponding to a first punch hole 141. The first driving member 210 drives the punch 220 to extend into the corresponding first punch hole 141 to punch the pipe 500. The punch 220 can be made of cemented carbide material to improve the punching efficiency and the service life of the punch 220. The punching module 200 is detachably mounted on the frame 400, and the number of punching modules 200 can be increased or decreased according to actual needs to meet the processing needs of pipes 500 of different sizes or punching numbers. In a preferred embodiment, the punching module 200 can adjust the installation position on the frame 400, and the second positioning block 140 and the first fixing mechanism 110 are both installed on the frame 400 in a detachable manner. When punching operations of pipes 500 of different sizes are required, the second positioning block 140, the support core rod 120 and the first fixing mechanism 110 can be replaced, and the installation position of the punching module 200 can be adjusted accordingly. In a preferred solution, the efficient pipe punching tooling machine not only provides multiple groups of expandable punching modules 200, but also can design a standardized module interface between the punching module 200 and the frame 400, allowing users to easily add or replace modules of different specifications and functions (such as punches 210 of different diameters, support core rods 120 of different materials, etc.) as needed. Through a highly modular design, the flexibility and adaptability of the equipment are improved to meet the changes in different users and processing needs. 3. Pipe feeding mechanism 300 (optional)

[0032] The pipe feeding mechanism 300 includes a pipe clamping device 310 and a second driving member 370. The pipe clamping device 310 is used to clamp the pipe 500 to be processed, and is designed to be adjustable to meet the clamping requirements of pipes 500 of different diameters. The second driving member 370 drives the pipe clamping device 310 to move, push the pipe 500 into the receiving hole 142 of the second positioning block 140, and sleeve it on the periphery of the supporting core rod 120. The pipe clamping device 310 and the third fixing mechanism 150 are respectively arranged on both sides of the second positioning block 140, and are used to cooperate to fix the two ends of the pipe 500 during the punching operation. Specifically, the pipe clamping device 310 may be a chuck structure, the pipe clamping device 310 is mounted on the bracket 320, a slider is mounted below the bracket 320, and the slider is used to slide along the guide rail 330, the guide rail 330 is connected to the rack 340, the rack 340 is meshed with the gear 350, and the gear 350 is rotated to drive the bracket 320, the pipe clamping device 310 and the pipe 500 to move toward the second positioning block 140, and the pipe 500 is clamped into the receiving hole 142. The rotation of the gear 350 can be achieved manually, and the second driving member 370 is designed as a handle structure. The operator rotates the handle to drive the gear 350 to rotate, and drives the pipe clamping device 310 to achieve feeding movement. In other embodiments, the second driving member 370 may also be an automatic driving mechanism, such as a motor, for automatically driving the pipe clamping device 310 to move. When the second driving member 370 is an automatic driving mechanism, in order to accurately limit the moving position of the pipe clamping device 310, a position sensor 361 can be installed on the frame 400, and the position sensor 361 interlocks and controls the second driving member 370 to realize the control of the feeding position of the pipe 500. When the second driving member 370 is a manual structure, the limiting mechanism can be a mechanical limiting structure, such as a stopper 362 installed on the movement trajectory of the pipe clamping device 310. When the pipe clamping device 310 moves to the position of the stopper 362, it can no longer move forward, thereby realizing the limit. In the preferred solution, a high-precision servo motor combined with advanced sensor technology (such as a laser rangefinder, a pressure sensor, etc.) can be used in the pipe feeding mechanism 300 to achieve high-precision positioning and stable clamping of the pipe 500. The clamping chuck of the pipe clamping device 310 can be driven by a high-precision cylinder or an electric push, so as to accurately control the clamping force of the chuck, reduce processing errors, and improve product quality. 4. Control system (not shown in the figure)

[0033] The efficient pipe punching tooling machine can further integrate a control system that controls the action sequence and time of each driving part, so as to realize an automated operation process and further improve the operation efficiency and accuracy. In a further optimized technical solution, an intelligent module can be integrated into the control system, which can automatically adjust the working parameters of the punching module 200 (such as the speed and punching force of the punch 210) according to the material, thickness, diameter and other parameters of the pipe 500 input by the operator to achieve the best processing effect. The module can also use sensors to monitor the status of the pipe 500 in real time, and combine machine learning algorithms to predict and adjust processing parameters to improve processing accuracy and efficiency. The control system can also further integrate remote monitoring and maintenance modules, develop remote monitoring software, and allow users to monitor the equipment operation status, processing progress and fault alarm information in real time through mobile phones, computers and other terminals; at the same time, provide remote fault diagnosis and maintenance guidance services. Combined with the Internet of Things technology, the intelligence level of the equipment can be improved, the maintenance cost can be reduced, and the user experience can be improved.

[0034] The working principle and use method of the high-efficiency pipe punching tooling machine of this embodiment are as follows: 1. The operator places the pipe 500 on the pipe clamping device 310 for clamping and fixing, and adjusts the positions of the pipe clamping device 310 and the supporting core rod 120 according to the size of the pipe 500.

[0035] 2. Start the device. The second driving member 370 is started to push the pipe clamping device 310 to send the pipe 500 into the receiving hole 142 of the second fixing mechanism and sleeve it on the outside of the supporting core rod 120.

[0036] 3. The third fixing mechanism 150 is actuated to fix and clamp the other end of the pipe 500.

[0037] 4. The first driving member 210 of each punching module 200 is started to drive the punch 220 to punch the pipe 500 through the first punch hole 141. The waste generated by the punching falls into the waste collection box below through the second punch hole 121, the discharge hole 122, and the chip groove 143.

[0038] 5. After the punching is completed, the third fixing mechanism 150 is released, and the second driving member 370 moves in the reverse direction to push the pipe 500 that has completed the punching operation back to the initial position or the next process.

[0039] 6. Repeat the above steps to continue punching the next pipe 500.

[0040] 7. Clean the waste collection box regularly, check and maintain the status of each component to ensure the normal operation of the device.
