[0002] A spinning machine is a mechanical device used to process metal tubes or cylindrical workpieces. It changes the shape of the workpiece by applying pressure and rotating, and is usually used to make round or symmetrical metal parts, such as pipes, cylinders, shafts, etc. A spinning machine usually includes a fixed workbench and a moving work head, on which rollers or molds for applying pressure and rotating are installed. Spinning machines are widely used in industries such as automobile manufacturing, aerospace, and pipeline processing, and are favored for their high efficiency and high precision processing characteristics. Different types of spinning machines can be used to process workpieces of different materials, including metal materials such as steel, aluminum alloy, and copper.

[0003] When a traditional spinning machine processes a round tube, the round tube to be processed is placed on a clamping block that matches its inner diameter, and then pressure is applied to the workpiece through a roller or a mold. The workpiece is rotated to roll along the curved surface of the mold or roller, thereby changing the cross-sectional shape of the workpiece.

[0004] However, when fixing the round tube, the traditional spinning machine uses a clamping block that matches the inner diameter of the round tube for clamping and fixing, which leads to the problem that only round tubes with a single inner diameter can be fixed and processed. Therefore, a spinning machine is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] When using the device to spin a round tube, first, the round tube is sleeved on the outer wall of the support plate 9, which is cut from a round tube in equal parts. After the sleeve is set, the hydraulic rod 12 can be started to push the slide bar 5 to slide inside the sleeve 4. When the slide bar 5 slides, one side of the connecting plate 7 will rotate inside the hinge frame 1 6, while the other side will rotate inside the hinge frame 2 8. The purpose of this is to push the support plate 9 outward. The support plate 9 slides along the limit groove 11 through the limit block 10 until the support plate 9 fits on the inner wall of the round tube and fixes it. This process ensures the stability and accuracy of the round tube during the spinning process, so that the finished product after spinning has good quality and precision, and also achieves the effect of fixing round tubes of different inner diameters.

[0034] Reference Figure 1 , Figure 3 and Figure 4The upper surface of the bottom plate 1 is fixedly connected to a fixed platform 2 13, and an electric slide rail 14 is arranged on the upper surface of the fixed platform 2 13. A mobile frame 15 is arranged inside the electric slide rail 14, and a side wall of the mobile frame 15 is fixedly connected to a side plate 16, and a rotating drum 17 is rotatably connected inside the side plate 16, and a partition 19 is fixedly connected inside the rotating drum 17. A motor 18 is fixedly connected to the side wall of the side plate 16, and the output end of the motor 18 is fixedly connected to the side wall of the partition 19. A fixed ring 20 is fixedly connected to the side wall of the rotating drum 17, and a battery 29 is fixedly connected to the side wall of the fixed ring 20. The wall is rotatably connected to a swivel ring 21, the side wall of the fixed ring 20 is rotatably connected to a swivel block 22, the side wall of the swivel block 22 is fixedly connected to a motor 23, the battery 29 is electrically connected to the motor 23, the output end of the motor 23 is fixedly connected to a screw rod 24, the side wall of the screw rod 24 is threadedly connected to a moving block 25, the side wall of the moving block 25 is rotatably connected to the side wall of the swivel ring 21, the inside of the swivel ring 21 is rotatably connected to a frame 26, the inside of the frame 26 is slidably connected to a splint 27, the inside of the splint 27 is fixedly connected to a roller 28, and the side wall of the splint 27 is rotatably connected to the side wall of the fixed ring 20.

[0035] After the round tube is fixed, the position of the mobile frame 15 can be changed by the electric slide rail 14 so that the end of the round tube that needs to be processed is inserted into the inside of the rotating ring 21. The staff drives the screw 24 to rotate by starting the motor 23, so that the moving block 25 moves, and then drives the rotating ring 21 to deflect. The frame 26 rotates inside the rotating ring 21 under the restriction of the clamping plate 27. When the frame 26 moves with the rotating ring 21, the clamping plate 27 will deflect on the fixed ring 20, and finally the roller 28 fits on the outer wall of the round tube. Then, start the motor 18, which will drive the rotating drum 17 to rotate inside the side plate 16, and then the fixed ring 20 will rotate, so that the roller 28 rotates on the outer wall of the round tube. As the motor 23 continuously drives the screw 24 to rotate, the rotating ring 21 slowly deflects on the side wall of the fixed ring 20, so that the spacing of the roller 28 gradually decreases, and gradually applies pressure to the round tube, and the round tube is processed by spinning. This process ensures accurate spinning of the round tube and ensures the quality and precision of the finished product. During the use of the device, the battery 29 will power the motor 23, and the battery 29 can be charged through the charging port provided on the battery 19 after the work is completed.

[0036] Working principle: When the equipment is used to spin a round tube, the round tube is first sleeved on the outer wall of the support plate 9. At this time, the hydraulic rod 12 is started to push the slide bar 5 to slide inside the sleeve 4. When the slide bar 5 slides, one side of the connecting plate 7 will rotate inside the hinge frame 1 6, and the other side will push the support plate 9 outward while rotating inside the hinge frame 2 8. The support plate 9 will slide along the limit groove 11 through the limit block 10 until the support plate 9 is attached to the inner wall of the round tube to fix it. After the fixation is completed, the moving frame 15 is changed by the electric slide rail 14, so that the end of the round tube to be processed is inserted into the inside of the swivel 21, and then the motor 23 is started, and the motor 2 3 will drive the screw 24 to rotate, so that the moving block 25 moves, and then drive the rotating ring 21 to deflect, the frame 26 will move with the rotating ring 21 and make the clamping plate 27 rotate on the fixed ring 20, and finally make the roller 28 fit on the outer wall of the round tube, then start the motor 18 to drive the rotating drum 17 to rotate inside the side plate 16, and then make the fixed ring 20 rotate, so that the roller 28 rotates on the outer wall of the round tube, as the motor 23 continues to slowly drive the screw 24 to rotate, the rotating ring 21 slowly deflects on the side wall of the fixed ring 20, so that the spacing of the rollers 28 gradually decreases, and gradually exerts pressure on the round tube, and finally achieves the effect of spin forming.
