[0014] (III) Beneficial effects
[0015] The beneficial effects of the utility model are as follows: in the actual implementation process, before the steel pipe body needs to be processed, the moving plate is first pulled, and the moving plate drives the two sliders to slide in the slide groove.

At this time, the return spring applies elastic force to the moving plate, and the elastic force drives the moving plate to move, and the moving plate drives the slider to slide in the slide groove. When the angle cutting is completed, the steel pipe body needs to be moved. At this time, the motor is started, and the motor drives the turntable to rotate. The turntable applies friction force to the two fixed rotating plates, and the friction force drives the two fixed rotating plates to rotate. At this time, the fixed rotating plates exert friction force on the steel pipe body. The friction force is applied to the body, and the friction force drives the steel tube body to move. At this time, the steel tube body drives the moving and rotating clamp to rotate. When the steel tube body moves, the measuring plate is pulled according to the size requirements, and the measuring plate drives the telescopic ruler to extend. When the area after the angle cutting corresponds to the position of the measuring plate, the area to be processed at this time is the target size, thereby avoiding the step of punching and cutting angles in the production of steel tube chairs, which often relies on manual pushing of metal pipes. This process is cumbersome and time-consuming. During the pushing process, the operator also needs to constantly measure the size after the angle cutting to ensure the cutting accuracy. This method is both laborious and prone to errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0023] Please refer to Figures 1 to 4As shown, the utility model is a CNC curved surface punching and cutting angle device for a steel pipe chair, comprising a frame 1, a base 2 is connected to the bottom of the frame 1, a support frame 3 is connected to the frame 1, a punching and cutting angle component 4 is connected to the frame 1, a rolling component 5 is connected to the support frame 3, a clamping component 6 is connected to the support frame 3, a steel pipe body 7 is arranged in the clamping component 6, a mobile clamping device 8 is connected to one side of the frame 1, a measuring device 9 is connected to the bottom of the mobile clamping device 8, and the mobile clamping device 8 includes a motor 801, a connecting plate 802, and a connecting plate 804. 02, a bearing 803 is connected through the connecting plate 802, a turntable 804 is connected to the motor 801, and two fixed rotating plates 805 are overlapped on the outside of the turntable 804, two sliding grooves 806 are provided in the connecting plate 802, and two sliders 807 are slidably connected in the sliding grooves 806, a moving plate 808 is connected to the slider 807, and two moving and rotating clamping blocks 809 are connected to the moving plate 808, a locking plate 810 is connected to the connecting plate 802, and a pull-back spring 811 is connected to the locking plate 810. In the actual implementation process, before the steel pipe body 7 needs to be processed, the moving plate 808 is first pulled. At this time, the moving plate 808 drives the two sliders 807 to slide in the slide groove 806. At this time, one side of the steel pipe body 7 is placed on the connecting plate 802, and then the moving plate 808 is released. At this time, the return spring 811 applies elastic force to the moving plate 808, and the elastic force drives the moving plate 808 to move. The moving plate 808 drives the slider 807 to slide in the slide groove 806. When the angle cutting is completed, the steel pipe body 7 needs to be moved. At this time, the motor 801 is started, and the motor 801 drives the turntable 804 to rotate. The turntable 804 applies friction to the two fixed rotating plates 805, and the friction drives the two fixed rotating plates 805 to rotate. At this time, the fixed rotating plates 805 apply friction to the steel pipe body 7, and the friction drives the steel pipe body 7 to move. At this time, the steel pipe body 7 drives the movable rotating clamp 809 to rotate, thereby avoiding the step of punching and cutting corners in the production of steel pipe chairs, which often relies on manual pushing of metal pipes. This process is both cumbersome and time-consuming.
[0024] Optionally, the steel tube body 7 is overlapped on the rolling assembly 5, and the steel tube body 7 is overlapped in the blanking and cutting corner assembly 4. In the actual implementation process, by setting the steel tube body 7 to cooperate with the rolling assembly 5, the steel tube body 7 can slide freely on the rolling assembly 5, which is convenient for the movement of the steel tube body 7.
[0025] Optionally, the motor 801 is connected to one side of the frame 1, and the connecting plate 802 is connected to one side of the frame 1. In the actual implementation process, by setting the motor 801 and the frame 1, the motor 801 cooperates with the frame 1, so that the frame 1 can limit the motor 801, thereby preventing the motor 801 from shaking during operation.
[0026] Optionally, the output end of the motor 801 is connected to the bearing 803, the fixed rotating plate 805 is rotatably connected to the connecting plate 802, and the return spring 811 is connected to the movable plate 808. In the actual implementation process, by setting the return spring 811, when the movable plate 808 is not pulled, the return spring 811 applies elastic force to the movable plate 808 to keep it stable. When the movable plate 808 is released, the return spring 811 applies elastic force to the movable plate 808, and the elastic force drives the movable plate 808 to move, so that it can be quickly reset.
[0027] Optionally, the measuring device 9 includes a housing 91, which is connected under the connecting plate 802, and a telescopic ruler 92 is connected inside the housing 91. In the actual implementation process, when the steel pipe body 7 moves, the measuring plate 94 is pulled according to the size requirement, and the measuring plate 94 drives the telescopic ruler 92 to extend. When the area after the angle cutting corresponds to the position of the measuring plate 94, the area to be processed at this time is the target size, which avoids the problem that the operator needs to constantly measure the size after the angle cutting to ensure the cutting accuracy during the pushing process, which is both laborious and prone to errors.
[0028] Optionally, a limit plate 93 is connected to one side of the telescopic ruler 92, and a measuring plate 94 is connected to the telescopic ruler 92. In the actual implementation process, by setting the telescopic ruler 92 and the limit plate 93, the telescopic ruler 92 cooperates with the limit plate 93, so that the limit plate 93 limits the telescopic ruler 92, thereby preventing the telescopic ruler 92 from being separated during the pulling process.
