[0002] The working principle of a rolling mill is to clamp the metal between two or more high-speed rotating working rolls to cause it to undergo plastic deformation and thus change its shape and size. Rolling mills can be divided into cold rolling mills and hot rolling mills, depending on the temperature state of the metal. Rolling mills are widely used in industries such as steel and non-ferrous metals, and are important equipment that is indispensable for metal processing. The common rolling mill support device is the roller seat support device, which is used to support the working rolls and support rolls of the rolling mill to ensure stability and accuracy during the rolling process.

They play the role of supporting and stabilizing the rolling mill rolls to ensure the accuracy and quality of the rolling process. Most roll support devices are equipped with a roll seat, which is a base structure that supports the rolls. It is usually made of solid metal material. The roll seat provides stable support by connecting to the main frame of the rolling mill.

[0033] Specifically, in the process of fixing the working roll, the cylinder 8 can be used to push the fixing seat 4 through the connecting frame 7, so that the fixing column 5 on the fixing seat 4 will be inserted into the interior of the working roll, and the motor 11 will be started. The motor 11 drives the forward and reverse screw rods 12 to start rotating. The rotation of the forward and reverse screw rods 12 will cause the movable blocks 13 on both sides to make synchronous relative movements toward the center. During the movement of the movable blocks 13, the transmission rod 14 will play a connecting role, lifting the outer expansion plate 15, and through the cooperation of the transmission rods 14 on both sides, the outer expansion plate 15 can be pushed out horizontally, thereby fixing the working roll. Through the above steps, the working roll can be firmly fixed on the fixing seat 4 to ensure the stability and accuracy of the working roll, and adapt to working rolls of different sizes to meet the needs of industrial production.

[0034] Reference Figure 2 and Figure 3 The outer wall of the fixed seat 4 is provided with a limit assembly, the limit assembly includes a limit rod 9 and a limit groove 10, the outer wall of the limit rod 9 is fixedly connected to one side of the outer wall of the fixed seat 4, the limit groove 10 is opened on the inner wall of the rotating block 6, and the outer wall of the limit rod 9 is slidably connected inside the limit groove 10;

[0035] Specifically, a limit rod 9 is provided on the rotating block 6, which can slide in a limit groove 10 opened on the inner wall of the rotating block 6, thereby preventing the fixed seat 4 from slipping inside the rotating block 6. At the same time, the limit rod 9 can be connected with the limit groove 10 so that the fixed seat 4 can be rotated through the rotating block 6, thereby facilitating the operation of the working roller fixed on the fixed seat 4.

[0036] Reference Figure 1 and Figure 4 , a left-right symmetrical driving rod 21 is rotatably connected inside the support frame 2, a slide groove 19 is opened on one side of the moving block 3, a slide plate 20 is rotatably connected on one side of the driving rod 21, and the outer wall of the slide plate 20 is slidably connected inside the slide groove 19, and the inner and outer walls of the driving rods 21 on both sides are rotatably connected with couplings 16, and the outer wall of one coupling 16 is fixedly connected to a hydraulic push rod 22, and the outer wall of the other coupling 16 is fixedly connected to the output end of the hydraulic push rod 22, and a rectangular array of slide rods 17 is fixedly connected inside the support frame 2, and the outer wall of the slide rod 17 is slidably connected to the inside of the moving block 3, and the outer wall of the slide rod 17 is sleeved with a spring 18, which is arranged on the outside of the moving block 3, one end of the spring 18 is fixedly connected to the outer wall of the support frame 2, and the other end of the spring 18 is fixedly connected to the outer wall of the moving block 3;

[0037] Specifically, the fixed seat 4 is connected to the moving block 3 through the rotating block 6. The spacing between the two working rollers can be adjusted through the moving block 3. The moving block 3 is connected to the fixed seat 4, and the adjustment is achieved by rotating the rotating block 6. The rotation of the rotating block 6 can change the relative position of the fixed seat 4 and the moving block 3, thereby adjusting the spacing between the working rollers. The hydraulic push rod 22 pushes the driving rods 21 on both sides. The staggered arrangement of the driving rods 21 can push the moving blocks 3 on both sides to both sides, thereby facilitating the control of the distance between the moving blocks 3. The moving block 3 slides on the outer wall of the sliding rod 17, which can limit the movement trajectory of the moving block 3. A spring 18 is sleeved on the sliding rod 17, which can buffer the movement process of the moving block 3, ensuring that the movement of the moving block 3 is smooth and the control accuracy is high. Through the above design, the distance between the two working rollers can be flexibly adjusted, and the movement trajectory of the moving block 3 can be limited and buffered, thereby meeting the working roller spacing control requirements under different working needs.

[0038] Working principle: When fixing the working roll, the cylinder 8 can push the fixed seat 4 through the connecting frame 7, so that the fixed column 5 on the fixed seat 4 is inserted into the inside of the working roll, and then the positive and negative screws 12 are driven to rotate by the motor 11, so that the positive and negative screws 12 can make the movable blocks 13 on both sides move synchronously relative to the center. During the movement of the movable block 13, the outer expansion plate 15 can be lifted up by the transmission rod 14, and the outer expansion plate 15 can be pushed out horizontally through the cooperation of the transmission rods 14 on both sides, so as to fix the working roll. The fixed seat 4 is connected to the moving block 3 through the rotating block 6, so that the spacing between the two working rolls can be adjusted by the moving block 3, and the driving rods 21 on both sides can be pushed by the hydraulic push rod 22. The staggered design of the driving rod 21 can push the moving blocks 3 on both sides to both sides, so as to facilitate the control of the spacing between the moving blocks 3. At the same time, the moving block 3 slides on the outer wall of the sliding rod 17, so as to limit the movement trajectory of the moving block 3, and the sliding rod 17 is provided with a spring 18, so as to facilitate the buffering of the movement process of the moving block 3.
