Description

Technical Field

[0001] This application relates to the field of hot rolling mills, and more particularly to a pneumatic pinch roll device for hot rolling mills. Background Technology

[0002] A hot rolling mill is a piece of equipment used in metal processing. It is primarily used for rolling metals above their recrystallization temperature to reduce rolling pressure and significantly reduce the cross-sectional area of ​​the workpiece. The main function of a hot rolling mill is to use rotating rolls to press metal billets, causing plastic deformation to obtain the desired shape and size. Hot rolling mills are widely used in the processing of metals such as steel and aluminum. In the steel industry, hot rolling mills are used to roll heated steel billets through multiple passes to ultimately produce steel plates, strips, and other products. Hot rolling technology is characterized by high productivity and low cost, making it suitable for large-scale production. In the aluminum processing industry, hot rolling mills are used to heat ingots above their recrystallization temperature, rolling them to obtain aluminum plates, strips, and other products. Hot-rolled aluminum has excellent plasticity and low energy consumption. Hot rolling mills often use pneumatic clamps for positioning. These pneumatic clamps are devices that use air pressure as a power source to clamp and position workpieces. They are mainly used in the hot rolling process to ensure the stability and accuracy of the workpiece during rolling.

[0003] Regarding the aforementioned technologies, the inventors believe that, due to the varying sizes of the processed materials, conventional pneumatic clamps are difficult to fit snugly against the surface of the processed materials during hot rolling. Insufficient friction between the pneumatic clamps and the surface of the processed materials during hot rolling can lead to slippage, thereby affecting the fixing effect of the processed materials and impacting the use of the hot rolling mill.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the problem of material shifting during hot rolling in a hot rolling mill, this application provides a pneumatic pinch roll device for a hot rolling mill.

[0006] The pneumatic pinch roll device for hot rolling mills provided in this application adopts the following technical solution:

[0007] A pneumatic pinch roll device for a hot rolling mill includes a housing and two mounting frames. A motor is fixedly mounted on the surface of the housing, and a transmission belt is mounted on the output end of the motor via a rotating shaft. A sliding frame is slidably mounted on the inner wall of the mounting frames. Two rotating rods are rotatably mounted on one end of the sliding frame.

A limit belt is driven to the surface of several rotating rollers. The surface of the transmission belt is slidably connected to the inner wall of the housing. The two rotating rods are symmetrically distributed about the mounting frame, and the dimensions of the inner wall of the rotating rod are adapted to the dimensions of the adjusting frame.

[0008] Preferably, both the sliding frame and the adjusting frame are rotatably mounted with connecting blocks, and an electric push rod is fixedly connected between the two connecting blocks.

[0009] Preferably, a spring is fixedly installed on the inner wall of the rotating rod, and the end of the spring away from the rotating rod is fixedly connected to the surface of the adjusting frame, and the center of the spring and the center of the rotating rod are on the same straight line.

[0010] Preferably, the inner wall of the connecting block is fitted with a bolt, the surface of the bolt is fixedly connected to the inner wall of the mounting bracket, and the center of the bolt is on the same straight line as the center of the connecting block.

[0011] Preferably, a threaded rod is rotatably mounted on the inner wall of the sliding frame, the surface of the threaded rod is threadedly connected to the inner wall of the mounting frame, and a rotating block is fixedly mounted on one end of the threaded rod, the center of the rotating block and the center of the threaded rod are on the same straight line.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By connecting the mounting frame to the top of the box, a rotating rod is mounted on the inner wall of the mounting frame via a sliding frame. An adjusting frame is slidably connected to the inner wall of the rotating rod. A limiting band is mounted on one end of the rotating rod and the adjusting frame via a rotating roller to increase the friction between the rotating roller and the workpiece. Connecting blocks are rotatably mounted on the surfaces of both the sliding frame and the adjusting frame. An electric push rod is installed between the two connecting blocks to facilitate the contact or separation of the limiting band from the workpiece surface.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a pneumatic pinch roll device for a hot rolling mill, referring to... Figure 1 - Figure 2The system includes a housing 1. After the housing 1 is installed and stabilized, a motor 2 is installed at one end of the housing 1. After the motor 2 is started, it controls the transmission belt 3 inside the housing 1 to drive the material. The material to be processed is placed on the upper end of the transmission belt 3 for easy material transfer. The mounting frame 4 is connected to the top of the housing 1. A rotating rod 6 is installed on the inner wall of the mounting frame 4 via a sliding frame 5. An adjusting frame 7 is slidably connected to the inner wall of the rotating rod 6. A rotating roller 8 is installed at one end of both the rotating rod 6 and the adjusting frame 7. A limiting belt 9 is connected to the surface of the rotating roller 8. The limiting belt 9 contacts the surface of the material to increase the friction between the rotating roller 8 and the material, effectively improving the fixing effect of the material during hot rolling and preventing the material from shifting and affecting the use of the hot rolling mill.

[0024] Reference Figure 2 Both the sliding frame 5 and the adjusting frame 7 have connecting blocks 10 rotatably mounted on their surfaces. An electric push rod 11 is installed between the two connecting blocks 10. The electric push rod 11 adjusts its own length to control the movement of the adjusting frame 7, making it easy to contact or separate the limiting band 9 from the surface of the workpiece, thus avoiding affecting the movement of the workpiece. A bolt 13 is snapped into the inner wall of the connecting block 10. The surface of the bolt 13 is installed with the inner wall of the sliding frame 5. The bolt 13 is used to fix the connecting block 10 and the surface of the sliding frame 5, thereby fixing the adjusting frame 7 at one end of the connecting block 10 at a suitable angle, which is convenient for limiting workpieces of different sizes. A spring 12 is installed between the rotating rod 6 and the adjusting frame 7. The spring 12 pulls the adjusting frame 7, thereby controlling the adjusting frame 7 to automatically rebound after the electric push rod 11 is closed, thus reducing the energy consumption generated by the electric push rod 11.

[0025] Reference Figure 3 - Figure 4 A threaded rod 14 is installed on the surface of the sliding frame 5. The surface of the threaded rod 14 is threadedly connected to the inner wall of the mounting frame 4, and a rotating block 15 is installed at one end of the threaded rod 14. The rotating block 15 controls the rotation of the threaded rod 14, thereby controlling the movement of the sliding frame 5 within the mounting frame 4. This facilitates the adjustment of the position of the limiting band 9, making it easier to fix larger processing materials. A slide rail 16 is slidably installed on the inner wall of the sliding frame 5. The bottom end of the slide rail 16 is connected to the top of the box 1. The slide rail 16 and the sliding frame 5 facilitate the control of the position of the limiting band 9, making it easier to fix processing materials of different lengths. Two rollers 17 are rotatably connected to the surface of the mounting frame 4. The surface of the rollers 17 slides against the top of the box 1. The rollers 17 reduce the friction between the mounting frame 4 and the slide rail 16, making it more convenient to move the mounting frame 4.

[0026] The implementation principle of the pneumatic pinch roll device for a hot rolling mill in this embodiment is as follows: A mounting frame 4 is connected to the top of the housing 1. A rotating rod 6 is mounted on the inner wall of the mounting frame 4 via a sliding frame 5. An adjusting frame 7 is slidably connected to the inner wall of the rotating rod 6. A rotating roller 8 is mounted on one end of both the rotating rod 6 and the adjusting frame 7. A limiting belt 9 is connected to the surface of the rotating roller 8 to facilitate contact with the surface of the workpiece via the limiting belt 9, thereby increasing the friction between the rotating roller 8 and the workpiece and preventing workpiece deviation from affecting the operation of the hot rolling mill. Connecting blocks 10 are rotatably mounted on the surfaces of both the sliding frame 5 and the adjusting frame 7. An electric push rod 11 is installed between the two connecting blocks 10 to facilitate the connection of the electric push rod 11 to the surface of the workpiece. The adjustment frame 7 moves by adjusting its own length, which facilitates the contact or separation of the limiting band 9 from the surface of the workpiece, avoiding any impact on the movement of the workpiece. The inner wall of the connecting block 10 is fitted with a bolt 13, the surface of which is installed on the inner wall of the sliding frame 5. This allows the connecting block 10 and the surface of the sliding frame 5 to be fixed with the bolt 13, thereby fixing the adjustment frame 7 at one end of the connecting block 10 at a suitable angle. This facilitates the limiting of workpieces of different sizes. A spring 12 is installed between the rotating rod 6 and the adjustment frame 7, which allows the adjustment frame 7 to be pulled with the help of the spring 12. This allows the adjustment frame 7 to automatically rebound after the electric push rod 11 is closed, thereby reducing the energy consumption generated by the electric push rod 11.

[0027] A threaded rod 14 can also be installed on the surface of the sliding frame 5. The surface of the threaded rod 14 is threadedly connected to the inner wall of the mounting frame 4, and a rotating block 15 is installed at one end of the threaded rod 14. The rotating block 15 is used to control the rotation of the threaded rod 14 and control the movement of the sliding frame 5 within the mounting frame 4. This facilitates the adjustment of the position of the limiting band 9, making it easier to fix larger processing materials. A slide rail 16 is slidably installed on the inner wall of the sliding frame 5. The bottom end of the slide rail 16 is connected to the top of the box 1, so that the position of the limiting band 9 can be easily controlled by the slide rail 16 and the sliding frame 5, making it easier to fix processing materials of different lengths. Two rollers 17 are rotatably connected to the surface of the mounting frame 4. The surface of the rollers 17 slides against the top of the box 1, so that the friction between the mounting frame 4 and the slide rail 16 can be reduced by the rollers 17, making it more convenient to move the mounting frame 4.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
