[0019] In other examples, to avoid confusion with the present invention, some technical features known in the art have not been described.

[0020] like Figures 1-3 As shown, a chamfering and flaring machine for processing gate valve pipes consists of a V-shaped plate 1, a feeding table 2, a fixed frame 3, an adjusting motor 4, a flaring disc 5, a pushing motor 6, a flaring device 7, a limiting frame 8, a slide rail 9, a slide rod 10, a clamping plate 11, a clamping seat 12, a processing table 13, a pushing electric cylinder 14, a driving electric cylinder 15, a flaring shaft 16, a flaring motor 17, and a transmission chain 18.

[0021] A hole-expanding device 7 is fixedly installed on the processing table 13. The hole-expanding device 7 is set inside the limiting frame 8. A feeding table 2 is provided on the side of the limiting frame 8.

[0022] The hole reaming device 7 includes a hole reaming frame, a hole reaming disc 5, a hole reaming motor 17, a hole reaming shaft 16, a drive cylinder 15, a push motor 6, and a push cylinder 14. A sliding plate is provided on the top of the hole reaming frame, and the sliding plate is set inside the limiting frame 8. The hole reaming motor 17 is set on the top of the hole reaming frame. The hole reaming disc 5 is set in the middle of the hole reaming frame and is fixedly connected to the hole reaming shaft 16 on its side. The hole reaming motor 17 is connected to the hole reaming shaft 16 through a transmission chain 18. The push motor 6 is set on the side of the limiting frame 8. The drive cylinder 15 is connected to the hole reaming shaft 16. The push cylinder 14 is connected to the hole reaming frame.

[0023] A slide rail 9 is installed on the inner wall of the limiting frame 8, and the slide rail 9 slides in cooperation with the slide plate.

[0024] The bottom of the skateboard is also equipped with a slide bar 10, which is connected to the drive motor 6.

[0025] The side of the limiting frame 8 is provided with a fixing component, which includes an adjusting motor 4, two clamps 12 and two clamping plates 11. The clamps 12 are located on the side of the limiting frame 8, the adjusting motor 4 is located on the side of the clamps 12 and its output end is connected to a screw. The screw is threaded to the bottom of the clamps 12, and the clamping plates 11 are located on the clamps 12.

[0026] The two clamps 12 have different transmission directions. The clamps 12 move in opposite directions, which can ultimately achieve simultaneous movement towards the center to clamp the valve tube, or simultaneous movement to both sides to release the valve tube.

[0027] There are two feeding platforms 2, located on both sides of the limiting frame 8. The two feeding platforms 2 can hold valve pipes simultaneously, eliminating the need for repeated material changes and reducing workload.

[0028] A V-shaped plate 1 is fixedly installed on the feeding platform 2. The V-shaped plate 1 is compatible with valve pipes of various shapes, making its application more extensive.

[0029] Working principle

[0030] The valve tube that needs to be flared is placed on the feeding platform 2. A V-shaped plate 1 is set on the feeding platform 2. The valve tube is placed in the groove on the V-shaped plate 1 for position limitation. One end of the valve tube abuts against the end of the feeding platform 2, and the other end abuts against the flaring plate 5. The valve tube is flared by the flaring plate 5. The electric cylinder 14 can be adjusted according to the size of the valve tube to push the flaring frame towards the feeding platform 2. After the flaring is completed, the electric cylinder 14 drives the flaring frame to reset. The electric cylinder 15 pushes the flaring frame to move to another feeding platform 2 position. Because the inner wall of the limiting frame 8 is equipped with a slide rail 9 and a slide rod 10, the movement of the flaring frame is smoother and the movement position can be limited.
