[0027] 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.
[0028] like Figures 1 to 5 As shown, this utility model provides a positioning device for niobium-coated disc screw rolling, including a conveying component 1. The conveying component 1 consists of several conveying rollers 12 and two conveying frames 11. The conveying rollers 12 are driven by a motor to achieve synchronous rotation. Several positioning components 2 are fixedly embedded on one side of the inner wall of the two conveying frames 11.
[0029] Positioning assembly 2 includes a positioning frame 21, which is fitted into two conveyor frames 11. The lower inner wall of the positioning frame 21 has an elongated groove 26. A bidirectional lead screw 25 is rotatably connected to both inner walls of the groove 26. A power motor 23 is fixedly connected to one end of the positioning frame 21. The output end of the power motor 23 passes through the positioning frame 21 and is fixedly connected to the bidirectional lead screw 25. Mounting brackets 27 are threaded onto the different directional threads of the bidirectional lead screw 25. Positioning rollers 28 are rotatably connected to the upper and lower inner walls of the mounting brackets 27. The outer surface of the positioning frame 28 is provided with a positioning groove 281, and the inner surface of the positioning frame 21 is equipped with a drive mechanism 24. The conveying roller 12 of the conveying component 1 realizes the stable conveying of the coiled rebar blank. In conjunction with the transmission structure of the power motor 23 in the positioning component 2 driving the bidirectional lead screw 25, the two mounting frames 27 can be driven to synchronously adjust the spacing of the positioning roller 28. At the same time, the drive mechanism 24 provides power to the positioning roller 28, realizing the accurate positioning and coordinated conveying of coiled rebar blanks of different diameters, greatly improving the adaptability of the device to coiled rebar blanks and the conveying stability.
[0030] Specifically, the positioning groove 281 is an arc-shaped groove, and the inner surface of the positioning groove 281 is engraved with anti-slip texture. The positioning groove 281 is set as an arc-shaped groove and engraved with anti-slip texture. The arc-shaped structure can accurately fit with the outer circular surface of the coiled rebar blank to increase the contact area. The anti-slip texture can enhance the friction between the positioning roller 28 and the coiled rebar blank, effectively preventing the coiled rebar blank from rotating or moving around in the circumference under high temperature environment, and ensuring the straightness of the coiled rebar blank conveying trajectory.
[0031] like Figures 1 to 5 As shown, the bottom plane of the positioning groove 281 is flush with the outer generatrix of the conveying roller 12. The outer surfaces of both the conveying roller 12 and the positioning roller 28 are coated with a high-temperature resistant coating. The bottom of the positioning groove 281 is flush with the outer generatrix of the conveying roller 12, ensuring that the coiled rebar blank transitions smoothly between the conveying roller 12 and the positioning roller 28 without any conveying jams. The high-temperature resistant coating on the outer surfaces of the conveying roller 12 and the positioning roller 28 can resist the high temperature of the coiled rebar blank, reduce the wear and tear on the components caused by high temperature, and extend the service life of the device.
[0032] Furthermore, an installation gap 13 is left between two adjacent conveyor rollers 12, and the positioning frame 21 is located in one of the installation gaps 13. The positioning frame 21 is installed in the installation gap 13 between adjacent conveyor rollers 12, without occupying additional external space of the device, which optimizes the compactness of the overall structural layout. At the same time, it makes the positioning component 2 closer to the conveying path of the coiled rebar blank, shortens the positioning response distance, and improves the positioning accuracy of the coiled rebar blank.
[0033] like Figures 1 to 5As shown, the drive mechanism 24 includes a drive motor 241 fixedly connected to the positioning frame 21. The output end of the drive motor 241 passes through the positioning frame 21 and is fixedly connected to a rotating shaft 242. The rotating shaft 242 is sleeved with two bevel gears 247, and two mounting frames 27 are sleeved together with the rotating shaft 242. The outer surfaces of the two bevel gears 247 are meshed with bevel gears 245. One end of the two positioning rollers 28 passes through the corresponding mounting frames 27 and is fixedly connected to the two bevel gears 245 respectively. The drive mechanism 24 drives the rotating shaft 242 to rotate through the drive motor 241. Through the meshing transmission of the bevel gears 247 and 245, the drive mechanism 24 synchronously provides power to the two positioning rollers 28, ensuring that the rotation speed of the positioning rollers 28 is matched with that of the conveying rollers 12, realizing the smooth conveying of the coiled rebar blanks, and avoiding the coiled rebar blanks from jamming or interrupting the conveying due to insufficient power.
[0034] It is worth noting that one end of the mounting frame 27 is provided with a through circular groove 248. A rotating ring 246 is rotatably connected to the inner surface of the circular groove 248. The rotating ring 246 is fixedly connected to the first bevel gear 247, and the rotating ring 246 and the first bevel gear 247 are slidably sleeved on the rotating shaft 242. The rotating ring 246 is rotatably connected to the circular groove 248 of the mounting frame 27, and is slidably sleeved on the rotating shaft 242 together with the first bevel gear 247. When the mounting frame 27 moves with the bidirectional screw 25 to adjust the spacing, the first bevel gear 247 can slide synchronously without affecting the rotation, and always maintain the meshing state with the second bevel gear 245. This ensures that the power transmission of the drive mechanism 24 to the positioning roller 28 is continuous and uninterrupted, and ensures the stable conveying of the coiled screw blank.
[0035] like Figures 1 to 5 As shown, two guide grooves 243 are formed on the outer surface of the rotating shaft 242. Guide blocks 244 that cooperate with the guide grooves 243 are fixedly connected to the inner surfaces of the bevel gear 247 and the rotating ring 246. The guide grooves 243 of the rotating shaft 242 cooperate with the guide blocks 244 of the bevel gear 247 and the rotating ring 246 to provide precise guidance for the sliding of the bevel gear 247, avoid deviation or jamming during the sliding process, ensure the stability of the meshing between the bevel gear 247 and the second bevel gear 245, further improve the operational reliability of the drive mechanism 24, and ensure the continuity of the conveying of the coiled screw blank.
[0036] It is worth emphasizing that guide frames 22 are fixedly connected to one end of each of the two mounting frames 27. The two guide frames 22 are in contact with the conveyor roller 12, and one end of each guide frame 22 is arc-shaped. The arc-shaped guide frames 22 on the two mounting frames 27 are in contact with the conveyor roller 12, which can pre-guide the coiled rebar billet before it enters the positioning roller 28, correct the conveying trajectory of the coiled rebar billet, and ensure that the coiled rebar billet accurately enters the positioning groove 281. At the same time, the arc-shaped structure avoids the guide frames 22 from scratching the surface of the coiled rebar billet, ensuring the quality of the raw materials for subsequent coiled rebar rolling.
[0037] Working principle and process: When in use, the motor drives the conveyor roller 12 of the conveyor assembly 1 to rotate synchronously. The coiled rebar billet is placed on the conveyor roller 12 and conveyed to the subsequent rolling process. According to the diameter specification of the coiled rebar billet, the power motor 23 is started to drive the bidirectional lead screw 25 to rotate. The bidirectional lead screw 25 drives the two mounting brackets 27 to move closer or further away synchronously through threads in different directions. The spacing of the positioning rollers 28 is adjusted to match the diameter of the coiled rebar billet.
[0038] Then, the drive motor 241 of the drive mechanism 24 is started. The output end of the drive motor 241 drives the rotating shaft 242 to rotate. The rotating shaft 242 drives the two bevel gears 247 to rotate synchronously through the cooperation of the guide groove 243 and the guide block 244. The bevel gear 247 meshes with the bevel gear 245, thereby driving the positioning roller 28 to rotate. During the conveying process of the coiled rebar billet, it is first pre-guided and corrected by the guide frame 22, and then enters the arc-shaped positioning groove 281 of the positioning roller 28. The anti-slip texture of the positioning groove 281 enhances the friction with the coiled rebar billet. Under the synergistic effect of the conveying roller 12 and the positioning roller 28, the precise positioning and smooth conveying of the coiled rebar billet are achieved, providing a stable raw material conveying guarantee for the subsequent coiled rebar forming and rolling.
