[0026] Please refer to Figure 1 , 2 , 3, 4, 5, 6 as shown, the present utility model provides a technical solution: a bending and forming device, including: a working box 1, the working box 1 is a cavity with an opening at the end; a feeding assembly is placed inside the working box 1, the feeding assembly includes a base 2, two limiting side plates 5 are slidably arranged on the top of the base 2, a bidirectional screw rod 4 for adjusting the distance between the two limiting side plates 5 is rotatably installed on the top of the base 2, a first linear module 6 for lifting the material and a second linear module 7 for conveying the material are arranged on the side of the limiting side plate 5, two first linear modules 6 are provided and vertically installed on one side of the limiting side plate 5, the second linear module 7 is horizontally installed above the first linear module 6, and the first linear module 6 and the second linear module 7 are vertically arranged; an angle flipping assembly is slidably placed on the lifting plate 10 in the middle of the working box 1, and a chuck 11 is rotatably connected to one side of the lifting plate 10; a bending assembly is placed at the end of the working box 1, the bending assembly includes a support disc 16 fixedly connected to the top of the working box 1, a limiting shaft is arranged on the top of the support disc 16, a rotating gear 17 is rotatably connected to the outside of the support disc 16, and a rotating shaft 18 is arranged to lift and lower on the top of the rotating gear 17 for rotating and bending.

[0027] It should be noted that the utility model is equipped with a PLC controller. The first linear module 6, the second linear module 7, the first motor 9 and the third motor 19 are all electrically connected to the PLC controller. According to the diameter of the pipe fitting, the distance between the two limit side plates 5 is adjusted to be the same as the diameter of the pipe fitting through the bidirectional lead screw 4. The pipe fittings are horizontally stacked between the two limit side plates 5. When feeding is required, the first linear module 6 jacks up the pipe fitting from the bottom, and the second linear module 7 penetrates the pipe fitting at the top through the chuck 11 so that it is located between the fixed shaft 21 and the movable limiting rod 3. The movable limiting rod 3 is driven by the first cylinder 23 to clamp and fix the pipe fitting. The rotating gear 17 makes the rotating shaft 18 move to different positions of the pipe fitting through the telescopic rotating shaft 18, thereby driving the pipe fitting to be bent through the rotating shaft 18, and driving the pipe fitting to rotate through the chuck 11, so that the pipe fitting rotates at different angles, thereby realizing bending at different angles for the pipe fitting.

[0028] Please refer to Figure 1 、 2 As shown in the figure, it further includes a conveying part. There are three groups of conveying parts. The three groups of conveying parts include two guide wheels 8. At the position corresponding to the guide wheels 8 at the bottom inside the working box 1, there is a first motor 9. The output end of the first motor 9 is fixedly connected to the guide wheels 8.

[0029] It should be noted that the three groups of conveying parts of the utility model are respectively located on one side of the working box 1 close to the limit side plate 5, one side of the adjusting screw 15, and one side close to the support plate 16. When the second linear module 7 pushes the pipe fitting between the two guide wheels 8, the pipe fitting is conveyed to one end by the first motor 9. Among them, the guide wheel 8 includes two parts, a mounting seat and a roller. The roller is threadedly connected to the top of the mounting seat, and the mounting seat is fixedly connected to the output end of the first motor 9. Different diameter rollers can be replaced according to the diameter of the conveyed pipe fitting.

[0030] Please refer to Figure 3 、 4 As shown in the figure, the base 2 is fixedly connected inside the working box 1. The bidirectional lead screw 4 is rotatably arranged at the end of the base 2.

[0031] It should be noted that the limiting side plates 5 of the utility model are symmetrically slidably set on the top of the base 2. By rotating the bidirectional screw rod 4, the two limiting side plates 5 are driven to the middle, and the lifting slide bar on the movable slide of the No. 1 linear module 6 is passed through, so that pipes of different diameters can be transported upward. When the No. 1 linear module 6 is transported upward to a specified height, the pipe at the top corresponds to the pushing slide bar on the side of the No. 2 linear module 7. The No. 2 linear module 7 drives the pushing slide bar to push the pipe to the middle of the chuck 11, and continues to transport it forward through the conveying part.

[0032] See also Figure 1 、 2 As shown in Figure 5, the angle flip assembly also includes a support frame 14 fixedly connected to the top of the working box 1, the middle part of the support frame 14 is threadedly connected with an adjusting screw 15, the bottom of the adjusting screw 15 is rotatably connected to the lifting plate 10, and a synchronous belt assembly 12 is provided on one side of the support frame 14, and a No. 2 motor 13 is fixedly connected to the bottom of the support frame 14, and the output end of the No. 2 motor 13 is transmission-connected to the chuck 11 through the synchronous belt assembly 12.

[0033] It should be noted that the chuck 11 of the utility model is a pneumatic three-jaw chuck, and the synchronous belt assembly 12 includes two synchronous pulleys and a synchronous belt that is sleeved on the outside of the two synchronous pulleys and is used to drive the two synchronous pulleys. One of the synchronous pulleys is fixedly connected to the chuck 11, and the other synchronous pulley is fixedly connected to the output end of the No. 2 motor 13. According to the diameter of the pipe, the adjusting screw 15 is rotated to make the adjusting screw 15 drive the lifting plate 10 to rise and fall, and the lifting plate 10 drives the axis of the chuck 11 to be concentric with the axis of the conveying pipe. When the pipe is rotated to adjust the angle, the chuck 11 fixes the pipe, and the No. 2 motor 13 drives the chuck 11 to rotate through the synchronous belt assembly 12, and the chuck 11 drives the pipe to rotate, thereby realizing bending at different angles.

The limiting shaft includes a fixed shaft 21 and a movable limiting rod 3. The fixed shaft 21 is fixed to the support plate 16, and the movable limiting rod 3 is fixedly connected to the output end of the No. 1 cylinder 23.

The rotating gear 17 is embedded with the No. 2 cylinder 24, and the output end of the No. 2 cylinder 24 is fixedly connected to the rotating shaft 18.

[0035] It should be noted that when the pipe fitting of the present utility model enters between the fixed shaft 21 and the movable limiting rod 3, the first cylinder 23 drives the movable limiting rod 3 to clamp and fix the pipe fitting between the movable limiting rod 3 and the fixed shaft 21. The second cylinder 24 drives the rotating shaft 18 to retract so that the top of the rotating shaft 18 is located below the pipe fitting. Thus, the third motor 19 and the driving gear 20 drive the rotating gear 17 to rotate, and the pipe fitting is conveyed to the left or right side of the pipe fitting through the rotating shaft 18, and then the workpiece is bent by the rotating gear 17 and the protruding rotating shaft 18.
