Description

Technical Field

[0001] This invention relates to the field of rolled product technology, specifically to a device for preventing abnormal torsional runout of rolled products. Background Technology

[0002] When the workpiece enters the rolling mill, the guide device provides precise guidance to ensure that the workpiece enters the roll pass accurately. This prevents the workpiece from twisting or jumping due to entry position deviation. Therefore, the device to prevent abnormal twisting and jumping of the workpiece is crucial. However, existing devices for preventing abnormal twisting and jumping of the workpiece have some shortcomings, such as:

[0003] The device described in application number CN202893835U, which is a pre-shear anti-torsion device for bar and wire rod mills, consists of a chute on a motor-driven roller conveyor, an upwardly inclined lower guide plate at the inlet section of the chute, and a downwardly inclined upper baffle at the outlet section. The lower guide plate is installed by hinges and fixing pins. The structure is relatively simple, but the function is relatively singular. It only addresses the torsion problem of rolled pieces during a specific roller conveyor operation, and its applicability is limited. It does not address the issue of rolled piece jump, which can easily cause rolled pieces to detach due to jump, leading to production safety problems. Summary of the Invention

[0004] The purpose of this invention is to provide a device to prevent abnormal torsional runout of rolled pieces, thereby solving the problem mentioned in the background art. Existing equipment on the market consists of a chute on a motor-driven roller conveyor, an upwardly inclined lower guide plate at the inlet section of the chute, and a downwardly inclined upper baffle at the outlet section. The lower guide plate is installed by hinges and fixing pins. The structure is relatively simple and the function is relatively singular. It only addresses the torsional problem of rolled pieces during a specific roller conveyor operation stage, and its application scope is limited. It does not address the runout problem of rolled pieces, which can easily cause the rolled pieces to detach due to runout, resulting in production safety problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for preventing abnormal torsional runout of rolled pieces, comprising a guide groove, a gantry frame, a limiting plate, a first bolt, and a third bolt;

[0006] A roller mechanism is provided above the guide groove. The roller mechanism includes a guide plate, a guide roller, a first bolt, and a spring. The spring applies pressure to the guide plate through its own elasticity and is pressed down by the guide roller to achieve the function of limiting the rolling stock.

[0007] A range pressing mechanism is provided above the guide plate. The range pressing mechanism includes a gantry frame, a limiting plate, and second bolts. The limiting plate and the guide plate are limited by four evenly distributed second bolts, thereby realizing the range pressing of the guide plate.

[0008] As a preferred technical solution of the present invention, the left side of the guide groove is rotatably connected to the guide plate, and the connection between the guide plate and the guide groove is formed by a shaft and a bearing to form a rotatable structure, and the guide groove is inclined as a whole;

[0009] The above technical solution adopts a shaft plus bearing structure at the connection, which allows the guide plate to rotate relative to the guide groove, and the guide groove is in an inclined state, which helps to transport and guide the rolled piece.

[0010] As a preferred embodiment of the present invention, a limiting block is installed on the upper right side of the guide plate by a third bolt, and a guide roller is sandwiched between the limiting block and the guide plate. The guide roller is a roughing mill guide wheel, and a bearing is configured at the installation location of the guide roller.

[0011] The above technical solution uses a roughing mill guide roller as the guide roller and a bearing is installed at the mounting point to reduce frictional resistance, improve the rotational flexibility of the guide roller, reduce damage to the rolled workpiece, and ensure the stability of the rolled workpiece during movement.

[0012] As a preferred technical solution of the present invention, the side of the guide groove is fixedly connected to the gantry frame, the gantry frame and the guide plate have the same inclination angle, the upper surface of the guide plate passes through the sliding gantry frame, and the first bolt is fixed at the center line position of the gantry frame;

[0013] Using the above technical solution, the first bolt is fixed at the center line of the gantry frame to provide support and connection foundation for the spring and guide plate.

[0014] As a preferred technical solution of the present invention, a limiting plate is fixedly connected to the inner side of the gantry frame, the limiting plate is slidably connected to the first bolt, and the width of the limiting plate is three times that of the gantry frame;

[0015] By adopting the above technical solution, the gantry and the guide plate adopt the same inclination angle to ensure that the downward pressing direction of the guide plate is within a certain range, which can be flexibly adjusted according to the actual situation of the rolled workpiece.

[0016] As a preferred technical solution of the present invention, the limiting plate is slidably connected to the two sides of the limiting plate, the second bolts are threaded through the limiting plate and connected to the guide plate, and the guide plate has four bolts arranged in a rectangular uniform shape.

[0017] Using the above technical solution, the second bolts are slidably connected to both sides of the limiting plate. The second bolts pass through the limiting plate and are threadedly connected to the guide plate. There are four guide plates in total, which are evenly arranged in a rectangle, so that the force on the guide plate is more uniform in all directions and the limiting effect on the rolled workpiece is better.

[0018] As a preferred embodiment of the present invention, the bottom surface of the limiting plate is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the guide plate, and the spring is fitted onto the outer ring of the first bolt.

[0019] By adopting the above technical solution, the guide roller can be adaptively adjusted through the elastic deformation of the spring, which can automatically adjust the pressure on the workpiece according to different conditions, effectively preventing the workpiece from twisting and jumping.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Solving the problem of torsional deviation: Based on the actual site conditions, after installing this device, the torsional deviation of the rolled pieces was basically solved, which greatly improved the success rate of the rolled pieces entering the subsequent rolling mill, reduced the scrap steel and production interruptions caused by abnormal rolled pieces, and improved production efficiency and product quality.

[0022] 2. Height self-adaptive adjustment: Utilizing simple mechanical principles, the height of the guide rollers of the device is self-adaptively adjusted under the same specifications. By adjusting the compression of the spring and the position of the guide plate, the guide rollers can adapt to workpieces of different heights, ensuring effective limiting of the workpieces. At the same time, external support is provided by adjusting the first and second bolts, which can meet the usage requirements of different rolling specifications and improve the versatility and flexibility of the device.

[0023] 3. Easy installation and maintenance: The device has a simple structure and the connection between each component is clear and easy to process, manufacture and install on site. During equipment maintenance and repair, it is easy to disassemble and replace parts, which reduces maintenance costs and maintenance difficulty, reduces equipment downtime and improves the overall operating efficiency of the equipment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-4 The technical solution of the present invention is: a device for preventing abnormal torsional runout of rolled pieces, comprising a guide groove 1, a gantry frame 2, a limiting plate 3, a first bolt 4, a second bolt 5, a guide plate 6, a guide roller 7, a spring 8, a limiting block 9, and a third bolt 10;

[0031] The roller mechanism consists of a guide plate 6, a guide roller 7, a first bolt 4, and a spring 8. Its core function is to limit the movement of the rolled piece. The spring 8 is fitted around the outer ring of the first bolt 4 and applies pressure to the guide plate 6 by means of its own elasticity, which in turn drives the guide roller 7 to press down and restrict the rolled piece on a predetermined path. The limiting block 9 is installed on the upper right side of the guide plate 6 by the third bolt 10, and the guide roller 7 is sandwiched between the two. The guide roller 7 is a roughing mill guide roller and is equipped with a bearing at the installation point, which greatly reduces frictional resistance, improves rotational flexibility, reduces damage to the rolled piece, and ensures the stability of the rolled piece movement.

[0032] The range pressing mechanism includes a gantry 2, a limiting plate 3, and a second bolt 5, which are used to control the pressing range of the guide plate 6. The gantry 2 is fixedly connected to the side of the guide groove 1. The gantry 2 and the guide plate 6 have the same inclination angle, which limits the direction of the pressing action of the guide plate 6. It can be flexibly adjusted according to the actual situation of the rolled workpiece. The first bolt 4 is fixed at the center position of the gantry 2 to provide support for the spring 8 and the guide plate 6. The limiting plate 3 is fixedly connected to the inner side of the gantry 2. The limiting plate 3 is slidably connected to the first bolt 4. Its width is three times that of the gantry 2. The second bolt 5 is slidably connected to both sides of the limiting plate 3. The second bolt 5 passes through the limiting plate 3 and is threadedly connected to four guide plates 6 arranged in a rectangular shape. This ensures that the guide plates 6 are subjected to uniform force in all directions and improves the limiting effect on the rolled workpiece.

[0033] The left side of the guide groove 1 is rotatably connected to the guide plate 6 through a shaft and bearing to form a rotatable structure. The guide groove 1 is tilted as a whole. This design allows the guide plate 6 to rotate relative to the guide groove 1, which greatly assists in the conveying and guiding of the rolled piece. At the same time, the bottom surface of the limiting plate 3 is fixed to one end of the spring 8, and the other end of the spring 8 is fixed to the guide plate 6. Through the elastic deformation of the spring 8, the guide roller 7 can achieve adaptive adjustment and automatically adjust the pressure on the rolled piece according to different conditions, effectively preventing the rolled piece from twisting and jumping.

[0034] Working Principle: When using a device to prevent abnormal twisting and jumping of rolled pieces, during the steel rolling process, the rolled pieces are conveyed through the guide trough 1. When the rolled pieces enter the device's working area, the guide roller 7 contacts the rolled pieces under the pressure of the spring 8, applying a certain pressure to limit the movement of the rolled pieces. Due to the elasticity of the spring 8, the guide roller 7 can automatically adjust its position according to the height and movement state of the rolled pieces, always maintaining effective clamping of the rolled pieces. When the rolled pieces show a tendency to twist or jump, the guide roller 7 can promptly stop its abnormal movement, ensuring that the rolled pieces are stably conveyed forward and smoothly enter the rolling mill. At the same time, the operator can adjust the height and pressing range of the guide plate 6 by adjusting the first bolt 4 and the second bolt 5 according to the actual production situation to adapt to different specifications of rolled pieces and ensure the best working effect of the device.

[0035] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
