Description

A rolling mill guide with independent adjustment on one side Technical Field

[0001] This utility model relates to the field of rolling mill equipment technology, specifically to a rolling mill guide single-sided independent adjustment device. Background Technology

[0002] In the steel rolling process, the adjustment accuracy of the inlet guide in the finishing mill directly affects the rolling quality and production efficiency of the strip. Traditional guide devices adopt a structure with screw connection and reducer transmission, and the opening degree of the two side wall plates is adjusted synchronously through linkage.

[0003] However, existing imported guides for precision rolling mills still have some drawbacks in practical use: most guides currently lack an independently adjustable structure for the side wall plates. When the strip steel comes into contact with the guide on one side due to deviation or other reasons, the wall plate cannot move independently, forcibly squeezing the edge of the strip steel, leading to unilateral edge cracking defects and affecting product quality. To avoid edge cracking, the traditional method has to enlarge the overall guide opening, but this can cause the three-point difference control of the strip steel to fail during rolling, reduce the stability of the steel passing through, and even cause production accidents such as strip head deviation and steel piling, increasing downtime maintenance costs.

[0004] To address this issue, we designed a single-sided independent adjustment device for the rolling mill guide. Summary of the Invention

[0005] The purpose of this invention is to provide a single-sided independent adjustment device for rolling mill guides to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a rolling mill guide single-sided independent adjustment device, including a guide screw connecting rod, a guide bearing seat is provided at the middle position of the guide screw connecting rod, a first guide screw and a second guide screw are rotatably connected to both sides of the guide screw connecting rod, the first guide screw and the second guide screw are symmetrically arranged on both sides of the guide bearing seat, and a guide wall plate is provided on both the first guide screw and the second guide screw.

[0007] Furthermore, a first coupling is provided at one end of the first guide screw, and a second coupling is provided at one end of the second guide screw. Both the first coupling and the second coupling are sleeved at a position close to the middle of the guide screw connecting rod.

[0008] Furthermore, a power source is installed in the middle of the guide screw connecting rod. There are two power sources, and the two power sources are respectively connected to the first coupling and the second coupling.

[0009] Furthermore, both the first guide screw and the second guide screw are threaded with guide nuts.

[0010] Furthermore, the bottom of the guide wall panel is provided with an installation groove, and the guide wall panel is snapped onto the guide nut through the installation groove.

[0011] Furthermore, a guide rod bushing is provided at one end of both the first guide rod and the second guide rod.

[0012] Furthermore, the guide screw bushing is positioned near both ends of the guide screw connecting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the independent driving of the first guide screw and the second guide screw, combined with the snap-fit ​​structure between the guide nut and the wall panel, allows for individual control of the retraction and extension of the inner and outer wall panels. When the strip steel is attached to a guide on only one side, it is only necessary to adjust the corresponding side wall panel to widen the gap, without needing to enlarge the guide as a whole, thus preventing edge cracking caused by unilateral compression and improving the edge quality of the strip steel.

[0015] 2. In this utility model, the traditional rough adjustment method of overall enlargement is abandoned. The spacing of the single-side wall panel is precisely matched according to the actual operating state of the strip steel, so as to avoid the fluctuation of the three-point difference of the strip steel caused by the guide opening being too large.

[0021] 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.

[0022] Please refer to Figures 1 and 2. This utility model provides a technical solution: a rolling mill guide independent adjustment device, including a guide screw connecting rod 1. A guide bearing seat 4 is provided at the middle position of the guide screw connecting rod 1. A first guide screw 2 and a second guide screw 3 are rotatably connected to both sides of the guide screw connecting rod 1. The first guide screw 2 and the second guide screw 3 are symmetrically arranged on both sides of the guide bearing seat 4. Guide wall plates 7 are provided on both the first guide screw 2 and the second guide screw 3. A first coupling 5 is provided at one end of the first guide screw 2, and a second coupling 6 is provided at one end of the second guide screw 3. Both the first coupling 5 and the second coupling 6 are sleeved near the middle position of the guide screw connecting rod 1. Two power sources are installed at the middle position of the guide screw connecting rod 1, and the two power sources are respectively connected to the first coupling 5 and the second coupling 6.

[0023] In practice, the power source, such as a motor, is started, and the power is transmitted to the first guide screw 2 and the second guide screw 3 through the first coupling 5 and the second coupling 6 respectively, causing the screws to start rotating. During power transmission, the couplings can compensate for any installation errors that may exist between the screws and the power source, ensuring smooth and reliable power transmission. As the first guide screw 2 and the second guide screw 3 rotate, due to the threaded engagement between the screws and the guide nut 8, the guide nut 8 will move linearly along the screw. The threaded drive precisely converts the rotational motion of the screws into the linear motion of the guide nut 8, providing power for the adjustment of the guide wall plate 7.

[0024] Referring to Figures 3 and 4, both the first guide screw 2 and the second guide screw 3 are threadedly connected to guide nuts 8. The bottom of the guide wall plate 7 is provided with an installation groove, and the guide wall plate 7 is snapped onto the guide nut 8 through the installation groove.

[0025] In practice, the bottom of the guide wall plate 7 is engaged with the guide nut 8 via a mounting slot. When the guide nut 8 moves linearly along the lead screw, it will drive the guide wall plate 7 to move synchronously. If it is necessary to adjust one side of the guide wall plate 7, the rotation of the lead screw on the corresponding side can be controlled separately.

[0026] Referring to Figure 1, a guide rod bushing 9 is provided at one end of both the first guide rod 2 and the second guide rod 3. The guide rod bushing 9 is located near both ends of the guide rod connecting rod 1.

[0027] In practical implementation, the guide screw bushing 9 provides precise guidance for the rotation and linear motion of the screw, preventing the screw from deviating or wobbling during movement. At the same time, due to its wear-resistant properties, it can effectively reduce friction between the screw and other components, reduce wear, and extend the service life of the screw and the device as a whole. In addition, it can withstand a certain radial load, distribute the force on the screw, and improve the stability and reliability of the screw's movement.

[0028] Working Principle: Upon starting the power source, power is transmitted through the first coupling 5 and the second coupling 6 to the first guide screw 2 and the second guide screw 3, respectively, causing the screws to rotate. During power transmission, the couplings compensate for any installation errors between the screws and the power source, ensuring smooth and reliable power transmission. As the first guide screw 2 and the second guide screw 3 rotate, the threaded engagement between the screws and the guide nut 8 causes the guide nut 8 to move linearly along the screws. This threaded drive precisely converts the rotational motion of the screws into the linear motion of the guide nut 8, providing power for the adjustment of the guide wall plate 7.

[0029] The bottom of the guide wall plate 7 is fastened to the guide nut 8 via a mounting slot. When the guide nut 8 moves linearly along the lead screw, it drives the guide wall plate 7 to move synchronously. If adjustment of one side of the guide wall plate 7 is required, the rotation of the lead screw on the corresponding side can be controlled independently. For example, when the strip steel is caught on one side of the guide, by controlling the rotation of the lead screw on the corresponding side, the guide nut 8 on that side drives the guide wall plate 7 to enlarge or shrink, realizing independent adjustment on one side, adjusting the running space of the strip steel, and solving the problem of the strip steel being caught on one side of the guide.

[0030] After the rolling mill finishes its production, first shut down the power equipment, such as the motor that provides power to the guide's independent adjustment device on one side, and stop the rotation of the lead screw.

[0031] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
