Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel rolling guide technology, specifically a multi-station steel rolling guide assembly. Background Technology
[0002] In steel section rolling, guide devices are installed before and after the roll passes to ensure the workpiece enters and exits the passes accurately and stably in a predetermined direction and state. Guide devices are also called induction devices. Regardless of the cross-sectional shape of the steel or billet being rolled, guide devices are required at the inlet and outlet of all roll passes; in other words, guide devices are an indispensable component of steel rolling production.
[0003] In the existing technology, such guide devices only have one rolling hole (called a single-hole guide). This means that when changing the rolled steel specifications, the corresponding guide needs to be replaced, making guide replacement work frequent. Each guide replacement is time-consuming, labor-intensive, and requires high technical skills for adjustment. Based on this, this application proposes a multi-station rolling steel guide assembly to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station rolling mill guide assembly, comprising a fixed chamber, wherein a multi-station switching mechanism for switching different guides is provided at the upper end of the fixed chamber, the multi-station switching mechanism comprising a column, a rotating ring, a rotating table, a fixed groove, a fixed plate, and a guide device, wherein a column is fixedly provided in the middle of the inner side of the fixed chamber, a rotating ring is movably provided at the upper end of the column via a bearing, a rotating table is fixedly provided at the upper end of the rotating ring, a plurality of fixed grooves are evenly provided on the outer surface of the upper end of the rotating table, a fixed plate is movably engaged inside the fixed groove, and a guide device is fixedly provided at the upper end of the fixed plate.
[0006] Preferably, a plurality of reinforcing plates are uniformly fixed between the rotating ring and the rotating platform, which can improve the structural strength between the rotating ring and the rotating platform.
[0007] Preferably, a gear ring is fixedly provided on the surface of the rotating ring, a reducer is fixedly provided on one side of the column surface, a gear is provided on the upper end of the reducer, and a motor is fixedly provided on one side of the reducer. The gear and the gear ring mesh with each other. The motor drives the reducer to rotate, thereby driving the gear to rotate. Then, the gear can rotate the gear ring, thereby driving the rotating ring and the rotary table to rotate. In this way, different models of guide devices can be switched to enter the working state as needed, so as to quickly adapt to the current processing conditions and improve the processing efficiency of the device.
[0008] Preferably, the reducer is a worm gear reducer, which can play a self-locking role. That is to say, as long as the motor does not rotate, the rotating ring and the rotating table cannot rotate. In this way, after the motor drives the rotating table to the target angle, the motor stops working, and the rotating table and the guide device can be automatically and quickly fixed at the angle, which can facilitate use.
[0009] Preferably, the power output end of the motor is connected to the power input end of the reducer, and the power output shaft end of the reducer is fixedly connected to the gear; the motor of this device is connected to the worm gear inside the reducer, and the worm wheel inside the reducer can be connected to the gear.

In this way, the fixing method of this device is convenient and quick, so that different guide devices can be easily replaced at any time.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model can store multiple guide devices at one time, thus enabling multi-station operation. When in use, the motor drives the reducer to rotate, which in turn drives the gear to rotate. The gear then rotates the gear ring, which in turn drives the rotating ring and the rotary table to rotate. In this way, different models of guide devices can be switched to enter the working state as needed, thus quickly adapting to the current processing conditions and improving the processing efficiency of the device.
[0013] 2. When using this utility model, the guide device of this device is installed by means of a fixed plate that is movably engaged in the fixed groove, which can quickly fix the guide device on the top of the rotating table. In order to prevent the fixed plate from sliding off the fixed groove, a pin can be inserted into the pin hole to prevent the fixed plate and the guide device from sliding loose.

[0018] 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.
[0019] Please see Figure 1-3 This utility model provides a technical solution: a multi-station rolling mill guide assembly, including a fixed chamber 1. The upper end of the fixed chamber 1 is provided with a multi-station switching mechanism for switching different guides. The multi-station switching mechanism includes a column 2, a rotating ring 3, a rotating table 4, a fixed groove 5, a fixed plate 6, and a guide device 7. The column 2 is fixedly installed in the middle of the inner side of the fixed chamber 1. The rotating ring 3 is movably installed on the upper end of the column 2 through a bearing. The rotating table 4 is fixedly installed on the upper end of the rotating ring 3. A plurality of fixed grooves 5 are evenly arranged on the outer surface of the upper end of the rotating table 4. The fixed plate 6 is movably engaged inside the fixed groove 5. The guide device 7 is fixedly installed on the upper end of the fixed plate 6.
[0020] A plurality of reinforcing plates 8 are uniformly fixed between the rotating ring 3 and the rotating platform 4. The structural strength between the rotating ring 3 and the rotating platform 4 can be improved by the reinforcing plates 8.
[0021] A gear ring 9 is fixedly mounted on the surface of the rotating ring 3, and a reducer 10 is fixedly mounted on one side of the surface of the column 2. A gear 11 is mounted on the upper end of the reducer 10, and a motor 12 is fixedly mounted on one side of the reducer 10. The gear 11 and the gear ring 9 mesh with each other. The motor 12 drives the reducer 10 to rotate, which in turn drives the gear 11 to rotate. Then, the gear ring 9 can rotate through the gear 11, which in turn drives the rotating ring 3 and the rotating table 4 to rotate. In this way, different models of guide devices 7 can be switched to enter the working state as needed, so as to quickly adapt to the current processing conditions and improve the processing efficiency of the device.
[0022] The reducer 10 is a worm gear reducer 10. The worm gear reducer 10 can play a self-locking function. That is to say, as long as the motor 12 does not rotate, the rotating ring 3 and the rotating table 4 cannot rotate. In this way, after the motor 12 drives the rotating table to the target angle, the motor 12 stops working, and the rotating table and the guide device 7 can be automatically and quickly fixed at the angle, which makes it convenient to use.
[0023] The power output end of the motor 12 is connected to the power input end of the reducer 10, and the power output shaft end of the reducer 10 is fixedly connected to the gear 11; the motor 12 of this device is connected to the worm gear inside the reducer 10, and the worm wheel inside the reducer 10 can be connected to the gear 11.
[0024] The outer surface of the rotating platform 4 has a pin hole 13 on one side of the fixing plate 6. The guide device 7 of this device is installed by the fixing plate 6 being movably engaged in the fixing groove 5, which can quickly fix the guide device 7 to the upper end of the rotating platform 4. In order to prevent the fixing plate 6 from sliding off the fixing groove 5, a pin can be inserted into the pin hole 13 to prevent the fixing plate 6 and the guide device 7 from sliding loose. In this way, the fixing method of this device is convenient and quick, so that different guide devices 7 can be easily replaced at any time.
[0025] Working principle: This device can store multiple guide devices 7 at one time, thus enabling multi-station operation. When in use, the motor 12 drives the reducer 10 to rotate, which in turn drives the gear 11 to rotate. The gear 11 then rotates the gear ring 9, which in turn drives the rotating ring 3 and the rotary table 4 to rotate. In this way, different models of guide devices 7 can be switched to enter the working state as needed, which can quickly adapt to the current processing conditions and improve the processing efficiency of the device.
[0026] Furthermore, when using this device, the guide device 7 is installed by means of a fixed plate 6 that is movably engaged in the fixed groove 5, which allows the guide device 7 to be quickly fixed to the upper end of the rotating table 4. In order to prevent the fixed plate 6 from sliding off the fixed groove 5, a pin can be inserted into the pin hole 13 to prevent the fixed plate 6 and the guide device 7 from sliding loose. In this way, the fixing method of this device is convenient and quick, so that different guide devices 7 can be easily replaced at any time.
