Description

Technical Field

[0001] This utility model relates to the field of cold rolling equipment, and more specifically, to a cold rolling equipment for silicon steel with low thickness fluctuation. Background Technology

[0002] Cold rolling is a metal processing method used to gradually reduce the thickness of metal materials and change their properties and shape. Cold rolling equipment usually consists of one or more pairs of rollers. The rolling force compresses and stretches the metal material, thereby gradually reducing its thickness. It can be used to process a variety of metal materials, such as aluminum and steel.

[0003] In the rolling production field, ensuring the uniformity of strip thickness after rolling is crucial to guaranteeing product quality. The operating condition of the rolls, especially the presence of eccentricity or wobbling, has a direct and significant impact on strip thickness. However, small-scale eccentricity and wobbling are difficult to detect directly and can only be judged during subsequent strip thickness fluctuation detection, which introduces a certain lag and makes timely adjustments difficult. This can easily lead to a large number of defective products when dealing with high-quality products.

[0004] Therefore, we have made improvements to this and proposed a low-thickness fluctuating cold rolling device for silicon steel. Utility Model Content

A groove is opened on the side surface of the two mounting plates that are close to each other.

[0011] As a preferred technical solution of this application, both ends of the rolling roll rotate through into the interior of the groove, and gears are sleeved on the outer surface of the rolling roll located inside the groove.

Laser displacement sensors 10 are installed on the inner walls of the left and right sides of the installation frame 4. An auxiliary component is provided on the installation frame 4. By using the cross arrangement of the two push rods 7 and the arrangement of the rotating shaft 9 close to the displacement plate 8, a lever principle is formed to amplify the movement of the rolling roll 3, thereby improving the detection range and accuracy and issuing timely reminders.

[0030] Example 2

[0031] The low-thickness fluctuation cold rolling apparatus for silicon steel provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the auxiliary components include two springs 11, which are fixedly connected to the inner walls of the left and right sides of the mounting frame 4, respectively. The ends of the two springs 11 are fixedly connected to two displacement seats 6, respectively. Baffles 12 are fixedly connected to the surfaces of the two displacement seats 6 that are far apart from each other. Both baffles 12 are in contact with the mounting frame 4. A contact roller 13 is provided on the upper surface of the displacement plate 8, and the contact roller 13 is in contact with the rolling roll 3. An installation groove 14 is opened on the upper surface of the vertical plate 2, and an installation plate 15 is slidably connected inside the installation groove 14. The two rolling rolls 3 are rotatably connected between the two installation plates 15. A pressing plate 16 is rotatably connected to the rear surface of the vertical plate 2, and a fixing block 17 is fixedly connected to the upper surface of the pressing plate 16. Two fixing blocks Mounting frames 4 are also fixedly connected between 17. Grooves 18 are provided on the adjacent side surfaces of the two mounting plates 15. The two ends of the rolling roll 3 rotate through into the interior of the groove 18. Gears 19 are sleeved on the outer surface of the rolling roll 3 inside the groove 18. The two gears 19 are meshed and connected. Connecting ears 20 are fixedly connected to the front sides of the vertical plate 2 and the pressing plate 16. Fixing bolts 21 are provided on the connecting ears 20. The two connecting ears 20 are fixedly connected by fixing bolts 21. With the rotatable setting of the pressing plate 16, the two rolling rolls 3 can be disassembled relatively easily. At the same time, the two meshing gears 19 can make the two rolling rolls 3 rotate synchronously, avoiding slippage when rotating by contact friction.

[0032] The upper mounting frame 4 is also equipped with a guide rod 5, a displacement seat 6, a push rod 7, a displacement plate 8, a rotating shaft 9, a laser displacement sensor 10, and a spring 11, which are mirror images of the lower structure.

[0033] The usage process of the silicon steel low-thickness fluctuation cold rolling device provided by this utility model is as follows:

[0034] When installing the rolling roll 3, first remove the fixing bolts 21, then lift the pressing plate 16, and then place the mounting plate 15 and the rolling roll 3 inside the mounting groove 14. After that, install the upper rolling roll 3 in the same way, and then connect the external drive source to the lower rolling roll 3 to start working. Once the rolling roll 3 deviates or shakes, it will drive the contact roller 13 to move synchronously. After the contact roller 13 moves, it will drive the displacement plate 8 to move synchronously. After the displacement plate 8 moves, it pushes the push rod 7 to move. Since the two push rods 7 are arranged crosswise, and the rotating shaft 9 is close to the displacement plate 8, the lower side of the push rod 7 moves a greater distance by using the lever principle. Then, the push rod 7 pushes the displacement seat 6 to move. During the movement of the displacement seat 6, the guide rod 5 restricts its own movement trajectory. When the displacement seat 6 moves, the spring 11 is compressed, and the displacement of the displacement seat 6 is detected by the laser displacement sensor 10. When the displacement seat 6 is detected to have moved, an alarm is issued.
