[0016] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses a forming spinning machine. (Refer to...) Figures 1-6A forming spinning machine includes a tailstock locking device 1. A tailstock 2 is fixedly connected to the top of the tailstock locking device 1. A hydraulic cylinder 4 is fixedly connected to the inner wall of the tailstock 2. An overflow valve 3 is fixedly connected to the oil inlet of the hydraulic cylinder 4. A slide 6 is fixedly connected to one side of the tailstock locking device 1. A retraction mechanism 8 is provided at the telescopic end of the hydraulic cylinder 4. The retraction mechanism 8 includes a sleeve 808, which is fixedly connected to the telescopic end of the hydraulic cylinder 4. A rotating head 807 is rotatably connected to the inner wall of the sleeve 808. A slide table 801 is fixedly connected to the telescopic end of the hydraulic cylinder 4. The bottom of the slide table 801 is slidably connected to the top of the slide table 6. A support rod 802 is fixedly connected to the inner wall of the slide table 6. The inner wall of the slide table 801 is slidably connected to the circumferential surface of the support rod 802. A spring 803 is provided on the circumferential surface of the support rod 802. One end of the slide plate 806 is fixedly connected to a sliding pressure plate 806. The inner wall of the slide plate 6 is fixedly connected to an installation tube 804. The inner wall of the installation tube 804 is fixedly connected to a pressure sensor 805. The inner wall of the installation tube 804 is slidably connected to the circumferential surface of the sliding pressure plate 806. After the part is fixed by the main shaft and the rotating head 807 in the forming spinning machine, the structure of the part will undergo thermal expansion during the reprocessing process. The sliding pressure plate 806 is in the state of extruding the pressure sensor 805. By controlling the overflow valve 3, the hydraulic oil in the hydraulic cylinder 4 is returned, so that the hydraulic cylinder 4 drives the rotating head 807 to move backward. The sliding pressure plate 806 is in the state of releasing the pressure sensor 805. The part is in the state of cold contraction. The overflow valve 3 will guide the lubricating oil into the hydraulic cylinder 4, so that it pushes the rotating head 807 to move towards the part, increasing the firmness of the rotating head 807, the part and the main shaft of the forming spinning machine.

[0017] Reference Figure 1 One side of the slide 6 is fixedly connected to a limit seat 7. There are two limit seats 7. When the slide table 801 moves to the limit position, it can prevent the slide 6 from colliding and damaging the mounting tube 804. Reference Figure 4 The circumferential surface of the sleeve 808 is fixedly connected to an oil guide pipe 10, and the inner wall of the sleeve 808 is provided with a lubrication groove 11. The oil guide pipe 10 installed on the sleeve 808 allows the user to introduce lubricating oil into the sleeve 808, thereby increasing the lubrication effect between the rotating head 807 and the sleeve 808. The lubrication groove 11 set in the sleeve 808 can be used to store lubricating oil, which can reduce the friction between the rotating head 807 and the sleeve 808. Reference Figure 4 and Figure 6 A heat-conducting ring 12 is fixedly connected to the inner wall of the sleeve 808, and a heat dissipation plate 15 is fixedly connected to the circumferential surface of the heat-conducting ring 12. The heat-conducting ring 12 installed in the sleeve 808 can guide the heat of the rotating head 807 to the heat dissipation plate 15. The user can cool the rotating head 807 by cooling the heat dissipation plate 15 through the cooling equipment. Reference Figure 5 A connecting rod 13 is fixedly connected to the circumferential surface of the sleeve 808. A baffle 5 is fixedly connected to one side of the connecting rod 13. The connecting rod 13 installed on the surface of the sleeve 808 can enhance the connection strength between the sleeve 808 and the baffle 5. The baffle 5 installed on one side of the connecting rod 13 can block the debris of the parts and prevent the debris of the parts from falling onto the surface of the slide block 6. Reference Figure 1 and Figure 5 A limiting slide frame 14 is fixedly connected to one side of the baffle 5. The inner wall of the limiting slide frame 14 is slidably connected to the surface of the slide block 6. The limiting slide frame 14 installed on one side of the baffle 5 can support the baffle 5 to slide stably on the surface of the slide block 6. Reference Figure 1 The inner wall of the slide block 6 is fixedly connected to the mounting rod 9. The inner wall of the slide table 801 is slidably connected to the circumferential surface of the mounting rod 9. The mounting rod 9 installed in the slide block 6 can support the slide table 801 to move on the surface of the slide block 6.

[0018] Working Principle: First, the main shaft and rotating head 807 of the forming spinning machine are brought close together and then the part is fixed. During the processing of the part driven by the main shaft of the forming spinning machine, and at the same time, the hydraulic cylinder 4 drives the rotating head 807 to fix the part, the part undergoes thermal expansion. The sliding pressure plate 806 is in the state of compressing the pressure sensor 805. By controlling the overflow valve 3, the hydraulic oil in the hydraulic cylinder 4 is returned, causing the hydraulic cylinder 4 to drive the rotating head 807 backward, reducing the stress of the rotating head 807 on the part. When the sliding pressure plate 806 is in the state of releasing the pressure sensor 805, the part is in the state of cold contraction. The overflow valve 3 can be controlled to guide the hydraulic oil into the oil inlet of the hydraulic cylinder 4, causing the hydraulic cylinder 4 to push the rotating head 807 towards the part, increasing the stability of the rotating head 807, the part, and the main shaft of the forming spinning machine. The stability of the rotating head 807, the part, and the main shaft of the forming spinning machine is controlled by the yielding mechanism 8, which can reduce the damage to the part and facilitate the user's disassembly and assembly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
