[0021] In the utility model, the feeding assembly includes support plates 8 symmetrically arranged on the top surface of the bending machine body 1, a connecting shaft 15 rotatably arranged between the support plates 8 and a receiving column 7 arranged on the outer wall of the connecting shaft 15. A plurality of material receiving grooves 13 are arranged in an annular manner with equal intervals on the outer wall of the receiving column 7. One end of the connecting shaft 15 movably passes through one of the support plates 8 and is provided with a servo motor 6. When the servo motor 6 is working, it stops for a period of time after rotating 90° and will only rotate after the copper tube processed on the bending machine body 1 is removed; and each rotation is only 90°; a material hopper 5 is provided above the receiving column 7, and the cross-section of the material hopper 5 is funnel-shaped, which is convenient for the automatic falling of the copper tube.

[0022] In the utility model, a circular cavity 18 is provided in the receiving column 7, and a plurality of suction holes 17 connected to the material receiving trough 13 are evenly provided on the inner wall of the circular cavity 18. A circular disk 4 is provided on the outer surface of one of the support plates 8, and a plurality of through holes 14 connected to the circular cavity 18 are provided in the circular disk 4. An air guide tube 12 is provided on the outer wall of the circular disk 4, and an air pump 3 is provided at one end of the air guide tube 12, and the air pump 3 is installed on the side of the support plate 8; the gas in the circular cavity 18 is extracted by the air pump 3, so that a negative pressure is formed in the circular cavity 18, so as to facilitate the fixing of the copper tube in the material receiving trough 13, and prevent the copper tube from falling when the receiving column 7 rotates, thereby ensuring that the bobbin is placed at the processing position of the bending machine body 1.

[0023] In the utility model, an arc-shaped sealing plate 16 is rotatably provided at the bottom of the circular cavity 18, and the arc-shaped sealing plate 16 is fixed on the inner wall of the support plate 8. Through the use of the arc-shaped sealing plate 16, it is convenient to block the suction hole 17 on the bottom surface, thereby releasing the fixation of the copper tube, and further facilitating the automatic falling of the copper tube.

[0024] In the present invention, support columns 2 are symmetrically provided on both side surfaces of the material hopper 5, and one end of the support column 2 is fixedly connected to the bending machine body 1, so as to facilitate fixing the material hopper 5, thereby ensuring the feeding of the copper tube.

[0025] In the present invention, the cross section of the hopper 5 is funnel-shaped, and the discharge port of the hopper 5 corresponds to the receiving column 7 directly above, so that the copper tube automatically falls into the hopper 13.

[0026] In the present invention, the blanking plate 9 is a U-shaped structure, which is convenient for taking away the processed copper tubes and realizing the blanking of the copper tubes.

[0027] Working principle: When the utility model is used, the copper tube vacuum pump 3 is first placed in the hopper 5, and then the copper tube falls from the bottom of the hopper 5 into the trough 13, and the vacuum pump 3 is turned on at the same time, and the gas in the circular cavity 18 is extracted by the vacuum pump 3, so that a negative pressure is formed in the circular cavity 18, and the bobbin in the trough 13 is further fixed, and then the servo motor 6 is started, and when the servo motor 6 works, the receiving column 7 will rotate 90° and then stop working, and after the receiving column 7 rotates 90°, the suction hole 17 at the bottom will be blocked by the arc-shaped sealing plate 16, thereby releasing the fixation of the copper tube, and then the copper tube automatically falls on the processing position of the bending machine body 1;

[0028] Then, the copper tube is bent by the bending machine body 1. After the processing, the electric telescopic rod 11 is opened. The movable end of the electric telescopic rod 11 moves backward, which drives the connecting rod 10 to move backward, thereby driving the blanking plate 9 to move backward, and further moves the processed copper tube to the rear end of the bending machine body 1, so as to realize the unloading of the copper tube. Then, the servo motor 6 continues to work after the blanking plate 9 is reset by the electric telescopic rod 11, so that the receiving column 7 rotates 90° and then stops working, and then the above steps are repeated.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
