Description

Technical Field

[0001] The utility model relates to the field of rolled pieces, and specifically relates to a guide device for rolled pieces. Background Art

[0002] A rolled piece refers to a steel billet that has entered a rolling mill and is an important raw material in the rolling process. Rolling is a metal processing technology that passes a metal billet through the gap between a pair of rotating rolling rolls. Due to the compression of the rolling rolls, the cross-section of the material is reduced and the length is increased by a pressure processing method. In this process, the rolled piece is plastically deformed under the compression of the rolling rolls, thereby obtaining certain dimensions, shapes, and properties.

[0003] During the operation of the existing rolled pieces, the guide plates are driven by hydraulic cylinders on both sides to guide the steel on the conveying track. However, when using two sets of hydraulic equipment, there may be a situation where the hydraulic equipment cannot operate simultaneously, or the movement distances of the equipment on both sides are different, resulting in the steel not being in the exact middle of the track. The deviation of the rolled piece from the center may cause the dimensional accuracy of the rolled steel not to meet the standards, such as deviations in parameters such as width and thickness, affecting the final quality of the product.

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a rolling piece guiding device, including side plates 1. A plurality of groups of first rollers 2 are rotatably installed between the two side plates 1 for conveying steel along the upper part of the first rollers 2. One side of the lower part of the side plate 1 is fixedly welded with a mounting plate 3. A motor 4 is flange-mounted on one side of the mounting plate 3. The power end of the motor 4 is connected with a power shaft 5 through a coupling. Power gears 6 are fixedly welded at both ends of the power shaft 5. Upper racks 7 and lower racks 8 are meshed and connected to the upper and lower ends of the power gears 6 respectively. One side of the upper rack 7 and the lower rack 8 is fixedly welded with a sliding plate 10. The sliding plate 10 penetrates the side plate 1 and is fixedly welded with a fixing frame 11. The motor 4 drives the power shaft 5 to rotate, drives the upper rack 7 and the lower rack 8 to move left and right through the power gears 6, and drives the fixing frame 11 to move left and right through the sliding plate 10. The fixing frames 11 on the same side are fixedly welded with the front and rear upper racks 7 and lower racks 8 respectively through the sliding plates 10, ensuring that the two fixing frames 11 are symmetrically arranged, so as to ensure that the moving distances of the two fixing frames 11 are the same. Two sliding rods 12 are fixedly welded on the side of the fixing frame 11 facing the side plate 1. The sliding rods 12 penetrate the side plate 1 and are fixedly welded with a fixing plate 13. The fixing frame 11 drives the fixing plate 13 through the sliding rods 12 to guide the steel on the upper part of the first rollers 2;

[0021] On the side of the upper rack 7 and the lower rack 8 away from the sliding plate 10, a limiting plate 9 is fixedly welded to prevent the driving gear 6 from disengaging from the upper rack 7 and the lower rack 8; a partition plate 23 is fixedly welded between the two side plates 1, and the partition plate 23 is arranged between the upper rack 7 and the first roller 2 to prevent the steel above the first roller 2 from overheating and the residue from falling to damage the gear and rack structure; two groups of extrusion rods 14 are slidably installed between the fixing plates 13. A fixing box 15 is fixedly welded to one side of the extrusion rod 14, and a fixing piece 17 is fixedly welded to the other end of the extrusion rod 14. A spring 18 is fixedly welded between the fixing piece 17 and the fixing plate 13, and the spring 18 is sleeved outside the extrusion rod 14. When the two fixing plates 13 move, the fixing box 15 is driven by the extrusion rod 14 to contact the steel. When the pressure on the steel is too large, the steel pushes the two fixing boxes 15, and the extrusion rod 14 moves to stretch the spring 18 through the fixing piece 17 to prevent the steel from being extruded and deformed; a number of second rollers 16 are rotatably installed inside the two fixing boxes 15 facing each other to facilitate the passage of the steel between the two fixing boxes 15; a limiting groove 19 is opened at the lower part of the partition plate 23, and a limiting block 20 is fixedly welded to the upper part of the upper rack 7. The limiting block 20 is slidably installed inside the limiting groove 19 to fix the position of the upper rack 7. A limiting piece 21 is fixedly welded to the lower part of the lower rack 8, and a limiting rod 22 is slidably installed inside the limiting piece 21. The two ends of the limiting rod 22 are fixedly welded to the side plate 1 to fix the position of the lower rack 8.

[0022] Working principle: When the utility model is in use, the motor 4 drives the power shaft 5 to rotate, drives the upper rack 7 and the lower rack 8 to move left and right through the driving gear 6, drives the fixing frame 11 to move left and right through the sliding plate 10, the fixing frame 11 drives the fixing plate 13 to move through the sliding rod 12, drives the fixing box 15 to contact the steel through the extrusion rod 14. When the pressure on the steel is too large, the steel pushes the two fixing boxes 15, and the extrusion rod 14 moves to stretch the spring 18 through the fixing piece 17 to prevent the steel from being extruded and deformed, and guides the steel above the first roller 2.
