[0023] Please see Figures 1-3 As shown, the embodiments of this utility model include:

[0024] A pneumatic pipe bending device includes a mounting base plate 1, a fixed component, a movable component, and a rotary drive component.

[0025] The fixed component and the movable component are arranged side by side on the upper surface of the mounting base plate 1. The fixed component is used to fix one end of the bend 2, and the movable component is used to bend the other end of the bend 2.

[0026] The fixing components include a clamping mold connecting base plate 3 and clamping mold pressing pusher 4, clamping mold pressing block 5, clamping mold connecting block 6, bent pipe clamping mold 7, clamping mold slide rail 8 and bent pipe wheel mold 9 on its surface.

[0027] The clamping mold connecting base plate 3 is horizontally fixed on the mounting base plate 1. The clamping mold pressing pusher 4, clamping mold pressing block 5, clamping mold connecting block 6, bending pipe clamping mold 7 and bending pipe wheel mold 9 are connected in sequence. The clamping mold slide rail 8 is set on the upper surface of the clamping mold connecting base plate 3. The clamping mold pressing block 5 and the clamping mold slide rail 8 are slidably connected by a dovetail groove structure. The clamping mold pressing pusher 4 drives the bending pipe clamping mold 7 and the bending pipe wheel mold 9 to clamp the bending pipe 2 accordingly.

[0028] The clamping block 5 and the clamping connection block 6 are connected by a longitudinally distributed dovetail groove structure, which facilitates replacement and installation.

[0029] The movable components include a guide mold connecting base plate 10, a guide mold clamping pusher 11, a guide mold clamping block 12, a guide mold connecting block 13, a bent pipe guide mold 14, and a guide mold slide rail 15.

[0030] The guide mold connecting base plate 10 is arranged parallel to the mounting base plate 1. The guide mold clamping pusher 11, guide mold clamping block 12, guide mold connecting block 13 and bending guide mold 14 are connected in sequence. The guide mold clamping block 12 and the guide mold slide rail 15 are slidably connected by a dovetail groove structure. The guide mold clamping pusher 11 drives the mold cavity of the bending guide mold 14 to fit with the bending pipe 2 for subsequent bending processing.

[0031] The guide mold clamping block 12 and the guide mold connecting block 13 are connected by a longitudinally distributed dovetail groove structure, which facilitates replacement and installation.

[0032] The guide mold connecting block 13 and the bending guide mold 14 are connected by a horizontally distributed dovetail groove structure, which enables the bending guide mold 14 to have lateral displacement. When the bending pipe 2 is bent, the bending guide mold 14 will have a certain displacement.

[0033] The side of the guide mold connecting block 13 is also provided with an elastic reset structure that is connected to the bending guide mold 14, so as to elastically reset the bending guide mold 14 after displacement during bending.

[0034] The elastic reset structure includes a fixed plate 16 and a spring screw 17. The fixed plate 16 is parallel to and fixed to the side of the guide mold connecting block 13.

The spring screw 17 is located outside the fixed plate 16 and its threaded end passes through the guide hole and is threadedly connected and fixed to the bending tube guide mold 14. The bending tube guide mold 14 achieves elastic reset through the extension / contraction of the spring and the fixed plate 16.

[0035] The bending guide mold 14 is also provided with a C-shaped bracket 18 at the outer end of the mold cavity. When bending a pipe 2 with a larger diameter, a mandrel 19 is inserted into one end of the pipe 2. The mandrel 19 passes through the bracket 18 to ensure stable support of the pipe 2 before bending.

[0036] The rotary drive assembly is located at the bottom of the mounting base plate 1 and drives the movable assembly accordingly, providing the driving force for bending the movable assembly.

[0037] The rotary drive assembly includes a rotary cylinder 20 and a rotary shaft 21.

[0038] The rotary cylinder 20 is fixed on the lower surface of the mounting base plate 1. The top drive end of the rotary cylinder 20 is provided with a rotary shaft 21 perpendicular to the top of the mounting base plate 1. The bottom of the guide mold connecting base plate 10 is fixed to the rotary shaft 21 through a rotary mounting plate 22. The rotary cylinder 20 drives the guide mold connecting base plate 10 to rotate.

[0039] The mounting base plate 1 has an angle sensor assembly 23 on one side of the bending tube mold 9, which corresponds to the guide mold connecting base plate 10. The guide mold connecting base plate 10 stops moving when it approaches the angle sensor assembly 23 to the bending position under the drive of the rotary cylinder 20.

[0040] The mounting base plate 1 is provided with multiple sets of equally spaced adjustment mounting holes 24 for fixing the angle sensor assembly 23. The position of the adjustment mounting holes 24 is selected according to the bending requirements of different bends 2.
