Detailed Implementation

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] See attached document Figures 1-4 The bending pipe fixing device provided by this utility model includes a support base 100. An arc-shaped groove is formed at the top of the outer wall of the support base 100. A clamping component for clamping the steel pipe is provided at the bottom of the inner wall of the arc-shaped groove. The clamping component includes a bottom clamping seat 110, which is installed on the inner wall of the arc-shaped groove. The bottom clamping seat 110 is mainly used to provide a position for installing and fixing the outer sealing plate 300 at the bottom. The outer sealing plates 300 are installed on both sides of the bottom of the inner wall of the bottom clamping seat 110. The outer sealing plates 300 are used to protect the worm gear 310. Simultaneously, the steel pipe clamp 320 allows the worm gear 310 to... The outer sealing plates 300 rotate between each other. Worm gears 310 are rotatably connected to both sides of the inner wall of the outer sealing plates 300. The outer sealing plates 300 and worm gears 310 are two-section structures aligned vertically. Steel pipe clamps 320 are fixed at the center of the inner wall of the upper and lower worm gears 310. When the upper and lower outer sealing plates 300 are aligned, the two worm gears 310 and the steel pipe clamps 320 can form a complete circle. The steel pipe clamps 320 can clamp and fix the outer wall of the steel pipe. The worm gears 310 can rotate under the action of the worm 421, so as to drive the steel pipe to rotate when needed.

[0023] A mounting bracket 420 is provided on the inner wall of the support base 100 and below the bottom clamping base 110. The outer wall of the mounting bracket 420 is fixed to both sides of the inner wall of the bottom clamping base 110. The mounting bracket 420 is provided to fix the worm 421 to the bottom end of the outer wall of the worm wheel 310. The front and rear ends of the inner wall of the mounting bracket 420 are rotatably connected to the worm 421. The worm 421 meshes with the bottom end of the outer wall of the worm wheel 310. When the worm 421 rotates, it can drive the worm wheel 310 to rotate through meshing. The two worm wheels 310 can form a circle after docking, so the worm 421 can drive the two worm wheels 310 to rotate. A fixing block is provided on the inner wall of the support base 100 and at the bottom rear side of the mounting bracket 420. A rotary motor 400 for driving is fixed at the rear end of the wall. The fixing block is set to fix the rotary motor 400 to the inner wall of the support base 100. The output shaft of the rotary motor 400 passes through the side wall of the fixing block and is equipped with a pulley mechanism 410. The upper end of the pulley mechanism 410 is connected to the corresponding end of the worm 421. The pulley mechanism 410 includes two pulleys and a transmission belt for driving the pulleys to rotate. The two pulleys can be fixed to the output shaft of the rotary motor 400 and the bottom end of the worm 421 respectively. The two pulleys are connected by the transmission belt. This allows the rotary motor 400 to drive the worm 421 to rotate after being powered on, so that the worm 421 can drive the worm wheel 310 to rotate.

[0024] A control component for controlling the opening of the clamping component is provided at the top of the outer wall of the support base 100 and at the rear side of the clamping component. An upper clamping seat 210 is provided at the top of the outer wall of the upper outer sealing plate 300. The outer sealing plate 300 is fixed to both sides of the outer wall of the upper clamping seat 210. The upper clamping seat 210 is provided for installing the outer sealing plate 300 at the upper position. The control component includes a hydraulic cylinder 200. The bottom end of the hydraulic cylinder 200 is hinged to the rear side of the top of the outer wall of the support base 100. The top output shaft of the hydraulic cylinder 200 is connected to the upper clamping seat 210. The outer wall of the upper clamping seat 210 is hinged at the corresponding position at the rear end. The upper clamping seat 100 is fixed with a support clamp 220 on both sides of the top of the outer wall and at the rear end of the outer sealing plate 300. The bottom of the outer wall of the upper clamping seat 210 is hinged to the inner wall of the support clamp 220. Specifically, the hydraulic cylinder 200 can drive the upper clamping seat 210 to rotate up and down around the support clamp 220 by extending and retracting the output end. This can drive the upper worm gear 310 and the bottom worm gear 310 to close or separate, thus facilitating the picking and putting of steel pipes.

[0025] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device. After assembly, an external power supply is connected to the device. Afterward, the operator can control the output end of the hydraulic cylinder 200 to retract, causing the upper clamping seat 210 to flip upward. This, in turn, drives the outer sealing plate 300 and the worm gear 310 to rotate upward and separate from the bottom worm gear 310. Afterward, the operator can remove the steel pipe or place it on the inner wall of the steel pipe clamp 320 at the bottom position using a robotic arm. After placement, the output end of the hydraulic cylinder 200 can be controlled to extend, causing the upper clamping seat 210 to drive the outer sealing plate 300 and the worm gear 310 to rotate upward and separate. The plate 300 flips downwards, and the steel pipe can be clamped by the steel pipe clamp 320 at the top. The bending mechanism (not shown in the figure) can then bend the steel pipe from both ends. During the bending process, the operator can also turn on the motor 400, which will drive the worm gear 421 to rotate through the pulley mechanism 410. When the worm gear 421 rotates, it will drive the worm wheel 310 to rotate, thereby causing the steel pipe to rotate. In this way, the angle of the bent steel pipe can be rotated, allowing the bending machine to perform bending processing on the steel pipe at more angles.

[0026] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
