[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 4 and Figure 5 This utility model provides a technical solution: a noise reduction and vibration damping AR pipe rolling mill buffer support structure, including a conveying mechanism 1 and a pallet 2 for conveying pipes. The pallet 2 is movably disposed inside the conveying mechanism 1. The conveying mechanism 1 includes a conveying frame 101 and a conveying roller 102. The conveying roller 102 is rotatably connected to the top of both sides of the conveying frame 101. A feeding mechanism 3 for realizing rapid tilting and feeding of pipes is provided between the conveying mechanism 1 and the pallet 2. Specifically, the formed pipe is conveyed by the conveying roller 102. When the pipe is conveyed to the position opposite to the stacking equipment, the unloading mechanism 3 lifts and tilts the pipe to unload it for subsequent stacking, thus improving the convenience of use.

[0018] exist Figure 1 , Figure 4 and Figure 5The unloading mechanism 3 includes a mounting frame 301 welded to the conveyor frame 101 and upright plates 307 symmetrically welded to the bottom of the pallet 2. The inner side of the mounting frame 301 is symmetrically provided with guide grooves 304. The guide grooves 304 include an upright groove and an inclined groove at the top of the upright groove. On the side of the two upright plates 307 that are far apart from each other, guide rod 1 305 and guide rod 2 306, which form a sliding structure with the guide grooves 304, are welded in sequence from top to bottom. Electric push rods 303 are symmetrically installed on the inner side of the mounting frame 301. The top of the electric push rod 303 is provided with a movable frame 302 connected to the guide rod 2 306 through a bearing. The electric push rod 303 is used to drive the movable frame 302 to rise and fall. The guide grooves 304 are used to cooperate with the movable frame 302, guide rod 1 305 and guide rod 2 306 to make the upright plate 307 move vertically and tilt at the same time.

[0019] Specifically, since the upright plate 307 and the movable frame 302 are slidably connected by guide rod 1 305, guide rod 2 306 and guide groove 304, and guide rod 2 306 is rotatably connected to the movable frame 302, and the guide groove 304 is composed of a vertical groove and an inclined groove, the support plate 2 at the top of the upright plate 307 can tilt the pipe while it moves vertically during the process of guide rod 1 305 moving from the vertical groove to the inclined groove, so that the pipe slides onto the support plate 4.

[0020] exist Figures 1-3 and Figure 5 In the middle: The front end of the conveyor frame 101 is provided with a shock absorption mechanism 7 to reduce noise while improving the shock absorption effect. The shock absorption mechanism 7 includes a support frame 701 welded to the front end of the conveyor frame 101 and a torsion spring 702 connected between the support frame 701 and the support plate 4. The torsion spring 702 absorbs impact energy through rotational deformation. Its reset function can reduce the number of repeated vibrations of the support plate 4 and avoid resonance amplification effect. The torsion spring 702 is made of a torsion spring material with a high damping coefficient, such as phosphor bronze, to optimize energy dissipation efficiency. A guide plate 704 is welded between the two support frames 701. A reset spring 703 is connected between the guide plate 704 and the support plate 4.

[0021] Specifically, since the support plate 4 is connected to the support frame 701 via a rotating shaft and a torsion spring 702, and the support plate 4 is connected to the guide plate 704 via a return spring 703, when the pipe falls, the end of the support plate 4 near the support plate 2 is slightly deflected downwards by a certain angle due to gravity. Then, under the reset action of the torsion spring 702 and the return spring 703, the lower end of the support plate 4 moves upwards, allowing the pipe to slide down the stacking equipment along the inclined surface of the support plate 4. This method of absorbing energy through rotation can improve the shock absorption effect while reducing noise, and the shock absorption effect is better than that of traditional vertical shock absorption.

[0022] exist Figures 1-3 and Figure 5In the middle: The top of the shock absorption mechanism 7 is rotatably connected to a support plate 4 for buffering and supporting the pipe through a rotating shaft. The end of the support plate 4 is set with an arc structure to reduce secondary collisions between the pipe and the stacking equipment.

[0023] Specifically, by setting the end of the support plate 4 to an arc-shaped structure, the trajectory of the pipe can be smoothly transitioned, reducing secondary collisions with the stacking equipment.

[0024] exist Figure 2 , Figure 3 and Figure 5 In the middle: Limiting rods 705 are equidistantly arranged at the bottom end of the guide plate 704 to form a sliding structure with the guide plate 704. The limiting rods 705 are used to support and guide the support plate 4 and the return spring 703.

[0025] Specifically, the limiting rod 705 serves to support and guide the support plate 4 and the return spring 703, thereby improving stability.

[0026] exist Figures 1-3 and Figure 5 In the middle: A buffer plate 5 is provided at the top of the support plate 4. The buffer plate 5 is made of a layer of high polymer elastic material to absorb vibration noise and attenuate micro-amplitude. A sound-absorbing plate 6 is provided at the bottom of the support plate 4. The sound-absorbing plate 6 adopts a honeycomb sound-absorbing structure to further reduce the propagation of mid- and low-frequency noise.

[0027] Specifically, the buffer plate 5 and sound-absorbing plate 6 are set at both ends of the support plate 4. The buffer plate 5 is made of a high-polymer elastic material layer, such as PU glue, and the sound-absorbing plate 6 adopts a honeycomb sound-absorbing structure, which can absorb vibration noise and achieve multi-level attenuation, significantly reducing noise and vibration impact.

[0028] In use, the formed pipe is conveyed by the conveying roller 102. When the pipe is conveyed to the position opposite to the stacking equipment, two electric push rods 303 are activated simultaneously, so that the electric push rods 303 extend and push the movable frame 302 to move vertically upward. Through the sliding action between the upright plate 307 and the movable frame 302 and the rotation action between the guide rod 306 and the movable frame 302, the support plate 2 at the top of the upright plate 307 can tilt the pipe while it moves vertically as the guide rod 305 moves from the vertical groove into the inclined groove, so that the pipe slides onto the support plate 4. At the moment the pipe falls, the end of the support plate 4 near the support plate 2 is slightly deflected downward by a certain angle due to gravity. Then, under the reset action of the torsion spring 702 and the return spring 703, the lower end of the support plate 4 moves upward, so that the pipe can slide down the stacking equipment along the inclined surface of the support plate 4 for subsequent stacking operations. This method of absorbing energy by rotation can improve the shock absorption effect and reduce noise. Electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source and controlled by a control box. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
