[0037] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0038] Embodiment 1:

[0039] A high-precision bending processing device for metal pipe fittings, as Figures 1 - 6 shown, includes a frame 1, a movable seat 17 and a drive disk 6. A bent seat 18 is installed on the top of the drive disk 6. A fixed seat 16 is installed on one side of the top of the frame 1. And limit assemblies 9 are provided on the fixed seat 16, the movable seat 17 and the bent seat 18. A drive motor 3 is installed on one side of the bottom of the frame 1. The output end of the drive motor 3 is connected to the drive disk 6. When it is necessary to bend the metal pipe, the drive motor 3 can be started. The drive motor 3 works to drive the drive disk 6 to rotate, thereby facilitating the bending of the metal pipe. A threaded hole 11 is opened at the middle position of the top of the drive disk 6. And a threaded post 10 is threadedly connected inside the threaded hole 11. The top end of the threaded post 10 is installed with a positioning post 8. When it is necessary to replace the positioning post 8, the staff can rotate the positioning post 8 through a knob, so that the threaded post 10 rotates. When the threaded post 10 is screwed out from the inside of the threaded hole 11, the positioning post 8 can be removed for replacement.

[0040] Specifically, the limiting component 9 includes chutes 901 opened at the tops of the fixed seat 16, the movable seat 17 and the bent seat 18, and two rotating shafts 906 provided at the tops of the fixed seat 16, the movable seat 17 and the bent seat 18. The rotating shafts 906 are connected to the fixed seat 16, the movable seat 17 and the bent seat 18 through bearings. A lead screw 902 is installed inside the chute 901 through a bearing, and a sliding seat 904 is sleeved on the outer wall of the lead screw 902. One end of the lead screw 902 is connected to a turntable 903. A toothed plate 905 is installed on the top of the sliding seat 904. Gears 907 and limiting plates 908 are respectively installed on the outer walls of the rotating shafts 906. The toothed plate 905 meshes with the gear 907. The sliding seat 904 is threadedly connected to the lead screw 902, and the outer wall of the sliding seat 904 fits with the inner wall of the chute 901, so that when the toothed plate 905 moves, it can drive the gear 907 to rotate, and the gear 907 drives the rotating shaft 906 to rotate, and then drives the limiting plate 908 to rotate.

[0041] Specifically, a fixed plate 14 is also installed on one side of the top of the frame 1, and a hydraulic cylinder 15 is installed on the outer surface of the fixed plate 14. The output end of the hydraulic cylinder 15 is installed with a movable seat 17 through a piston rod. When it is necessary to clamp the metal pipe, the hydraulic cylinder 15 can be started to make the piston rod extend, thereby driving the movable seat 17 to move, so as to clamp and fix the metal pipe. A limiting groove 13 is also opened at the top of the frame 1, and a limiting block 12 is arranged inside the limiting groove 13. The top of the limiting block 12 is connected to the movable seat 17. When the movable seat 17 moves, it will drive the limiting block 12 to slide inside the limiting groove 13, thereby improving the stability of the movable seat 17 when it moves. Slots 20 are opened on the fixed seat 16, the movable seat 17 and the bent seat 18, and clamping blocks 19 are inserted into the slots 20. The clamping blocks 19 can be inserted into the slots 20, which is convenient for quickly installing the clamping blocks 19.

[0042] Refer to Figures 1 - 5 , support frames 2 are installed on both sides of the bottom of the frame 1. The top of the drive disk 6 is flush with the top of the frame 1. The support frames 2 can support the frame 1, thereby improving the stability of the frame 1. The bottom of the limiting plate 908 fits with the top of the clamping block 19. After the limiting plate 908 fits with the top of the clamping block 19, the clamping block 19 can be limited to prevent the clamping block 19 from tilting upward.

[0043] Embodiment 2:

[0044] On the basis of the above Embodiment 1, in order to improve the stability of the drive disk 6 when it rotates, the following structure will be set up.

[0045] Refer to Figures 1 - 3, on the other side of the top of the frame 1, there is an activity slot 5. Inside the activity slot 5, there are multiple activity blocks 4. The activity slot 5 is annular, and the activity blocks 4 are connected to the bottom of the driving disk 6. When the driving disk 6 rotates, it will drive the activity blocks 4 to slide inside the activity slot 5, thereby improving the stability of the driving disk 6 when it rotates.

[0046] Embodiment Three:

[0047] Based on the above Embodiment One, in order to facilitate the accurate measurement of the rotation angle of the driving disk 6, the following structure is set up.

[0048] Refer to Figures 1 - 2 , both the outer wall of the driving disk 6 and the other side of the top of the frame 1 are provided with scale values 7. The setting of the scale values 7 facilitates accurately calculating the rotation angle of the driving disk 6, so that the metal pipe fittings can be bent more accurately, and the accuracy of the bending angle can be improved.

[0049] The working principle of the present utility model is as follows: First, before using the device, the power supply can be connected first, then the metal pipe fitting is placed on the frame 1, and one end of the metal pipe fitting passes through the gap between the bending seat 18 and the positioning post 8. After the metal pipe fitting is placed, the hydraulic cylinder 15 can be started, so that the piston rod extends and then drives the movable seat 17 to move. The movable seat 17 drives the clamping block 19 inserted therein to move, so as to cooperate with the clamping block 19 on the fixed seat 16 to clamp and fix the metal pipe fitting;

[0050] Then start the driving motor 3. When the driving motor 3 works, it drives the driving disk 6 to rotate. The driving disk 6 drives the bending seat 18 to rotate, and the bending seat 18 cooperates with the positioning post 8 to bend the metal pipe fitting. At the same time, the setting of the scale value 7 facilitates accurately understanding the rotation angle of the driving disk 6;

[0051] When it is necessary to replace the clamping block 19, the staff can rotate the screw rod 902 through the turntable 903. When the screw rod 902 rotates, it drives the sliding seat 904 to move, then drives the toothed plate 905 to move, and drives the gear 907 to rotate, and then drives the limiting plate 908 to rotate. When the limiting plate 908 no longer fits with the clamping block 19, the staff can take out the clamping block 19, and then insert the clamping block 19 to be replaced into the slot 20. After insertion, the staff can reverse-rotate the screw rod 902 through the turntable 903. After the screw rod 902 rotates in the reverse direction, it drives the sliding seat 904 to move, and drives the toothed plate 905 to move back to its original position. The toothed plate 905 drives the gear 907 to rotate, and the gear 907 drives the limiting plate 908 to rotate, so that the limiting plate 908 fits with the top of the clamping block 19, thereby achieving the purpose of limiting the clamping block 19;

[0052] When the positioning post 8 needs to be replaced, the staff can rotate the positioning post 8 through the knob, so that the threaded post 10 rotates. After the threaded post 10 is screwed out from the inside of the threaded hole 11, the positioning post 8 can be removed for replacement, so as to replace different types of positioning posts 8.

[0053] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
