[0021] A base 2 is fixedly installed on the top of the operating table 1. A pipe clamp 7 is fixedly installed on the top of the base 2. A clamping cylinder 9 is installed on the top of the base 2, and there are two sets of clamping cylinders 9. The output end of the clamping cylinder 9 is fixedly connected to a second telescopic rod 10. One end of the second telescopic rod 10 is fixedly connected to a movable pipe clamp 8. The fixed pipe clamp 7 and the movable pipe clamp 8 are respectively provided with clamping grooves 20. The pipe to be processed is placed in the clamping groove 20 of the fixed pipe clamp 7. The clamping cylinders 9 on both sides push the second telescopic rod 10 and the movable pipe clamp 8 to move towards the center, cooperating with the fixed pipe clamp 7 to clamp the pipe, ensuring that the pipe is stable and does not shift during processing. A compression cylinder 3 is fixedly installed on the right side of the operating table 1. The output end of the compression cylinder 3 is fixedly connected to a first telescopic rod 4. One end of the first telescopic rod 4 is connected to a motor fixing plate 14. A motor 5 is fixedly installed on the top of the motor fixing plate 14. The output end of the motor 5 is fixedly connected to a compression head 6. The compression cylinder 3 is activated. Pushing the first telescopic rod 4 and the motor fixing plate 14 to the left, the extrusion head 6 driven by the motor 5 is gradually inserted into the tube end. The extrusion head 6 has an extrusion cavity 13 inside, and the extrusion cavity 13 is elliptical cone-shaped. The motor 5 drives the extrusion head 6 to rotate. Under the action of rotation and axial propulsion, the elliptical cone-shaped extrusion cavity 13 performs uniform radial extrusion on the tube end, forcing the tube end to plastically deform and form a preset shape. A top plate 15 is fixedly installed on the right side of the operating table 1. A positioning guide cone 16 is fixedly installed on the right side of the top plate 15. The positioning guide cone 16 on the top plate 15 assists in aligning the extrusion head 6 with the central axis of the tube during the extrusion process to ensure forming accuracy. As for the setting of the connecting plate 12, the connecting plate 12 is fixedly installed on the top of the base 2. There are two sets of connecting plates 12, and clamping cylinders 9 are fixedly installed on the top of the two sets of connecting plates 12. Since the connecting plate 12 provides rigid support, the clamping cylinder 9 will not shift its position due to the reaction force when it operates, ensuring uniform clamping force. Regarding the setting of the reinforcing plate 17, a reinforcing plate 17 is fixedly installed on the left side of the operating table 1, and two sets of reinforcing plates 17 are provided. One side of the two sets of reinforcing plates 17 is fixedly connected to the top plate 15. During the extrusion process, the axial force applied by the extrusion cylinder 3, the rotational torque of the motor 5, and the reaction force of the pipe are all transmitted to the operating table 1 and the top plate 15. The reinforcing plate 17 can effectively disperse these loads, prevent structural deformation or vibration, reduce the elastic deformation of the operating table 1 and the top plate 15 under stress, and avoid deviation of the pipe end forming size due to structural shaking. Regarding the setting of the material taking groove 11, a material taking groove 11 is opened on the top of the fixed pipe clamp 7, and the material taking groove 11 passes through the fixed pipe clamp 7 and the base 2. After the pipe is extruded and formed, the operator can directly reach into the tool or hand through the material taking groove 11 to quickly take out the formed pipe from the slot 20 of the fixed pipe clamp 7 without disassembling the pipe clamp or moving the device parts significantly. This eliminates the step of manually loosening the clamp or adjusting the structure in the traditional device, and improves the material taking efficiency.Regarding the motor mounting plate 14, a groove is provided on the bottom of the motor mounting plate 14, and a guide rail 19 is provided on the top of the operating table 1. The motor mounting plate 14 is slidably connected to the operating table 1 through the guide rail 19. After processing is completed, the extrusion cylinder 3 retracts, and the motor mounting plate 14 smoothly returns to its initial position along the guide rail 19, ready for the next operation. The guide rail 19 is designed to be suitable for high-frequency reciprocating motion, meeting the needs of continuous processing in automated production lines. Regarding the motor mounting base 18, a motor mounting base 18 is fixedly installed on the top of the motor mounting plate 14, and there are two sets of motor mounting bases 18. The two sets of motor mounting bases 18 are arranged in a linear array on the motor mounting plate 14. The linear array arrangement of the two sets of motor mounting bases 18 means that they are evenly distributed along the length of the motor mounting plate 14, providing symmetrical support force, even force distribution, reducing wear on individual mounting bases, reducing the risk of loosening after long-term use, and improving the durability of the equipment. Regarding the setting of the support legs 21, support legs 21 are fixedly installed under the operating table 1, and there are four sets of support legs 21. The four sets of support legs 21 are cylindrical and are evenly distributed under the operating table 1 to provide stable support and ensure that the device does not tilt or shake during processing. The cylindrical structure distributes the force evenly and can effectively distribute the weight of the operating table 1 and each component to prevent local deformation. All electrical equipment in this device is powered by an external power source.

After the pipe is extruded and formed, the operator can directly reach into the material picking groove 11 with a tool or hand to quickly remove the formed pipe from the slot 20 of the fixed pipe clamp 7 without disassembling the pipe clamp or moving the device parts significantly. This eliminates the need for manually loosening the clamp or adjusting the structure in traditional devices, thus improving material picking efficiency. Regarding the setting of the motor fixing plate 14, the motor fixing plate 14 has a groove on its lower part, and a guide slide rail 19 is set on the upper part of the operating table 1. The motor fixing plate 14 is slidably connected to the operating table 1 through the guide slide rail 19. After processing is completed, the extrusion cylinder 3 retracts, and the motor fixing plate 14 smoothly returns to its initial position along the guide slide rail 19, ready for the next operation. The design of the guide slide rail 19 is suitable for high-frequency reciprocating motion, meeting the needs of continuous processing in automated production lines.

Regarding the arrangement of the reinforcing plate 17, the reinforcing plate 17 is fixedly installed on the left side of the operating table 1, and two sets of reinforcing plates 17 are provided. One side of each set of reinforcing plates 17 is fixedly connected to the top plate 15. During the extrusion process, the axial force applied by the extrusion cylinder 3, the rotational torque of the motor 5, and the reaction force of the pipe are all transmitted to the operating table 1 and the top plate 15. The reinforcing plate 17 can effectively disperse these loads, prevent structural deformation or vibration, reduce the elastic deformation of the operating table 1 and the top plate 15 under stress, and avoid deviations in the forming dimensions of the pipe end due to structural shaking.
