Description

Technical Field

[0001] The utility model belongs to the technical field, and in particular relates to a twenty-high rolling mill press-down monitoring device. Background Art

[0002] The twenty-high rolling mill uses a linear displacement sensor to detect the displacement of the rolling mill. As the equipment ages, jamming may occur during the rolling process, causing inaccurate readings of the displacement, which in turn leads to tolerance fluctuations during the strip rolling process and the scrapping of the strip.

It is characterized in that it also includes a round shaft, a pressure plate, an adjustment sleeve A, an adjustment sleeve B, an adjustment screw, a square key, and a bolt. A circular groove is provided inside the card plate. The adjustment sleeve A and the adjustment sleeve B are arranged in the circular groove and are fixedly connected to the card plate through the adjustment screw. A through-hole is provided in the middle of the adjustment sleeve A, the middle of the adjustment sleeve B, the middle of the card plate, and the middle of the upper end of the press-down screw. One end of the round shaft is connected to the rotary encoder through a coupling, and the other end is arranged in the deep circular hole. The adjustment sleeve A and the adjustment sleeve B are provided with a keyway on the corresponding round shaft. The pressure plate is sleeved on the round shaft and located in the middle of the upper end of the card plate. The pressure plate is close to the upper end of the adjustment sleeve A and is fixed to the card plate through bolts. The adjustment sleeve A and the adjustment sleeve B can be adjusted in different directions, thereby eliminating the bidirectional side clearance on both sides of the square key.

[0017] The following is a further detailed description of the specific implementation methods of the present invention by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and to facilitate its implementation.

[0018] like Figure 1 As shown, the utility model provides a twenty-high rolling mill pressure monitoring device, including a frame fixed base 3 and a magnetoelectric displacement sensor 1 and a magnetic scale 5 arranged on the frame fixed base 3, the magnetoelectric displacement sensor 1 is connected to the slider 2, and the slider 2 cooperates with the magnetic scale 5.

[0019] Specifically, if Figure 1As shown, the magnetic scale 5 is fixedly mounted on the frame fixed base 3 by bolts. A support is provided on the frame fixed base 3, and the magnetoelectric displacement sensor 1 is provided on the support, and the support is fixedly mounted on the frame fixed base 3 by bolts. One end of the slider 2 is connected to the magnetic scale 5, and the other end of the slider 2 is connected to the magnetoelectric displacement sensor 1. The slider 2 is also connected to the depression actuator 7 on the twenty-high rolling mill through the connecting rod 4. The depression actuator 7 drives the slider 2 to move synchronously. During the movement of the slider 2, the magnetoelectric displacement sensor 1 and the magnetic scale 5 detect the depression amount of the depression actuator 7. By replacing the existing linear displacement sensor with the magnetoelectric displacement sensor 1 and the magnetic scale 5 with higher detection accuracy to detect the depression amount, the detection feedback accuracy of the equipment and the stability of the equipment operation are greatly improved, and the inaccurate depression displacement reading that causes tolerance fluctuations and strip scrapping during the strip rolling process is effectively avoided.

[0020] like Figure 1 and Figure 2 As shown, the slider 2 is connected to the buffer mechanism, and the buffer mechanism is located between the magnetoelectric displacement sensor 1 and the magnetic scale 5. The slider 2 is located between the buffer mechanism and the pressing actuator 7. The buffer mechanism includes a buffer rod 6 and a buffer spring 8 and a limit block 9 arranged on the buffer rod 6. The buffer spring 8 is located between the slider 2 and the limit block 9. The buffer spring 8 is a cylindrical coil spring and a compression spring. The buffer rod 6 is fixedly set on the frame fixed base 3. The slider 2 is provided with a through hole for the buffer rod 6 to pass through. The buffer spring 8 is sleeved on the buffer rod 6. When the slider 2 moves downward, it will compress the buffer spring 8. The buffer spring 8 plays a buffering and shock-absorbing role to reduce the impact. The limit block 9 is threadedly connected to the buffer rod 6. The limit block 9 can be a nut. The buffer rod 6 is provided with an external thread. By adjusting the position of the limit block 9, the compression amount of the buffer spring 8 can be adjusted.
