[0002] Streetlights are lighting fixtures that provide illumination for roads. To improve the lighting effect or for aesthetic purposes, many streetlight poles are bent to a certain extent. When bending the pole, people usually hold it in place by hand, which results in poor stability and affects the proper bending process.

[0003] In the prior art, patent (CN217570327U) proposes a lamp post bending device, including a worktable, a clamping assembly, a guide plate, and a swinging extruder. The worktable is rotatably connected to an upwardly extending shaft. The clamping assembly is disposed on the worktable and includes a pressure seat and a lower pressure member that slides vertically above the pressure seat to cooperate with the pressure seat in clamping and fixing a metal tube. The guide plate is rotatably connected to the shaft and located on the outlet side of the clamping assembly. The outer peripheral wall of the guide plate is provided with an inwardly recessed receiving groove to accommodate the metal tube. The swinging extruder is fixedly connected to the shaft and disposed near the outer periphery of the guide plate. It is used to rotate around the axis of the shaft to press against the peripheral wall of the metal tube so that the metal tube is bent and formed in the receiving groove. Through the clamping assembly fixing the metal tube and the extrusion cooperation between the guide plate and the swinging extruder, the stability of the metal tube bending is improved.

[0021] This utility model provides a bending device, including a workbench 101 and a processing mechanism 102. The processing mechanism 102 includes a mounting frame 103, a turntable 104, a supporting screw 105, a supporting plate 106, a pushing assembly 107, a bending assembly 108, and a correction assembly 109. The pushing assembly 107 includes a side frame 110, a pushing motor 111, a pushing screw 112, and a push plate 113.

[0022] In this specific embodiment, the correction component 109 and the mounting bracket 103 are both fixedly connected to the worktable 101, the bending component 108 is rotatably connected to the worktable 101, the pushing component 107 is fixedly connected to the worktable 101, the supporting plate 106 is fixedly connected to the supporting screw 105, the turntable 104 is fixedly connected to the supporting screw 105, the supporting screw 105 is rotatably connected to the mounting bracket 103, the push plate 113 is threadedly connected to the pushing screw 112, and the top... One end of the push screw 112 is rotatably connected to the side frame 110, and the other end of the push screw 112 is fixedly connected to the output end of the push motor 111. The push motor 111 and the side frame 110 are both fixedly connected to the worktable 101. Both bending cylinders 118 are rotatably connected to the inner frame 117. The inner frame 117 is fixedly connected to the output end of the cylinder 115. The cylinder 115 is fixedly connected to the swing frame 116, and the swing frame 116 is fixedly connected to the output end of the bending motor 114. The bending motor 114 is fixedly connected to the worktable 101. Each positioning roller 121 is rotatably connected to the correction frame 119. Each adaptation roller 120 is fixedly connected to the correction frame 119. The correction frame 119 is fixedly connected to the worktable 101. Both guide rollers 124 are rotatably connected to the platform 122. Each stabilizing column 123 is fixedly connected to the platform 122. The push plate 113 in the currently installed push assembly 107 is connected to the push motor 111 and the push screw 11. Under the action of 2, the metal pipe can be continuously pushed to move towards the bending assembly 108. The inner frame 117 in the bending assembly 108 is adjusted in position by the cylinder 115, and the bending motor 114 drives the swing frame 116 to rotate, thereby realizing the bending of the pipe. The bending angle is controlled by the cylinder 115 to achieve the bending of the inner frame 117. This design is simple and solves the problems of limited bending degree of metal pipe and non-adjustable bending angle, which are easily restricted and inconvenient to use in actual use.

[0023] The correction component 109 and the mounting bracket 103 are both located above the workbench 101, the bending component 108 is located above the workbench 101, the pushing component 107 is located on one side of the workbench 101, the supporting plate 106 is located at the lower end of the supporting screw 105, the turntable 104 is located at the upper end of the supporting screw 105, and the supporting screw 105 is located above the mounting bracket 103.

[0024] Secondly, the push plate 113 is located around the push screw 112, one end of the push screw 112 is located inside the side frame 110, the push motor 111 and the side frame 110 are both located on one side of the worktable 101, the two bending cylinders 118 are both located inside the inner frame 117, the cylinder 115 is located on one side of the swing frame 116, and the bending motor 114 is located below the worktable 101. The push motor 111 drives the push screw 112 to rotate, thereby adjusting the position of the push plate 113 with threads that are compatible with the push screw 112, and pushing the pipe to move. During this period, the two guide rollers 124 on the platform 122 are always in contact with the pipe to be processed, so as to avoid bending of the middle section of the pipe that is not in contact with the bending cylinder 118, which would affect the bending efficiency.

[0025] Meanwhile, each positioning roller 121 is located inside the correction frame 119, and each adapting roller 120 is located inside the correction frame 119. The correction frame 119 is located above the worktable 101, and the two guide rollers 124 are located above the platform 122. Each stabilizing column 123 is located below the platform 122. Before the pipe is bent, it is first passed through the correction frame 119. The multiple adapting rollers 120 and the positioning rollers 121 inside the correction frame 119 straighten the pipe, keeping it vertical before bending. The process also cleans impurities around the pipe. Then, one end of the pipe is placed on the push plate 113, and the other end passes through the mounting bracket 103 and fits against the two bending cylinders 118 inside the built-in frame 117. The cylinder 115 is activated. When the built-in frame 117 is away from the swing frame 116, the bending angle is smaller. Conversely, the pipe bending angle is larger. Under the action of the bending motor 114, the swing frame 116 is rotated to achieve pipe bending. This achieves control over the pipe bending angle, and the bending node can be determined by the position of the pipe pushed by the push plate 113, thus improving bending efficiency.

[0026] In this embodiment, the push motor 111 drives the push screw 112 to rotate, thereby adjusting the position of the push plate 113, which has a thread that is compatible with the push screw 112, and pushing the pipe to move. During this period, the two guide rollers 124 on the platform 122 are always in contact with the pipe to be processed, so as to avoid bending of the middle section of the pipe that is not in contact with the bending cylinder 118, which would affect the bending efficiency. Before the pipe is bent, it is first passed through the correction frame 119. The multiple adaptation rollers 120 and the positioning rollers 121 inside the correction frame 119 straighten the pipe and keep it in a straight position. Before bending, the pipe is in a vertical position, and impurities around the pipe are cleaned. Then, one end of the pipe is placed on the push plate 113, and the other end passes through the mounting bracket 103 and fits against the two bending cylinders 118 in the built-in frame 117. The cylinder 115 is activated. When the built-in frame 117 is away from the swing frame 116, the bending angle is smaller, and vice versa. Under the action of the bending motor 114, the swing frame 116 is rotated to achieve pipe bending, thereby achieving control of the pipe bending angle. The bending node of the pipe can be determined by the position of the push plate 113 pushing the pipe, thus improving bending efficiency.
