Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled plate shape control, in particular to a plate shape meter measuring roller capable of automatically controlling position accuracy. Background Art

[0002] A contact-type flatness meter, a flatness measurement device, is located at the mill exit. Its measurement principle is based on the principle that the fundamental cause of strip flatness defects is uneven stress distribution along the width of the strip. By measuring the stress distribution across the width of the strip, flatness defects can be identified.

[0003] Usually, the shape meter measuring roll, lower working roll and stop roll together form a specific wrap angle structure. This wrap angle should be evenly distributed along the roll body direction to ensure measurement accuracy. However, when the parallelism or horizontality between the shape meter measuring roll and the stop roll exceeds the preset position deviation accuracy, this deviation will cause the distribution of the wrap angle in the axial direction to become uneven, thereby affecting the accurate determination of the true tension value. This measurement error causes control deviation, which is not conducive to the overall improvement of the strip shape quality. Utility Model Content

[0006] Therefore, the purpose of the present utility model is to provide a shape meter measuring roller that can automatically control the position accuracy. It is suitable for solving the problem that the shape meter measuring roller, the lower working roller and the stop roller form an angle structure, which needs to be evenly distributed to ensure accurate measurement. If the parallelism or horizontality of the measuring roller and the stop roller is out of tolerance, the angle distribution is uneven, which affects the tension measurement, causes control deviation, and reduces the quality of the strip shape.

[0024] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0025] Reference Figure 1 - Figure 3 , which is an embodiment of the present invention, provides a plate shape meter measuring roller capable of automatically controlling position accuracy, including a main unit 100 and an adjustment unit 200.

[0026] The main unit 100 includes a disc 101 and a ring 102 that matches the disc 101. A rotating shaft is installed on one side of the ring 102, which is connected to the parts through the rotating shaft to ensure that the disc 101 and the ring 102 can rotate.

[0027] The adjustment unit 200 includes three groups of expansion and contraction cylinders 214 fixedly installed between the disc 101 and the ring 102. The top of the expansion and contraction cylinder 214 is composed of four groups of first fan-shaped plates 201, second fan-shaped plates 202 and third fan-shaped plates 203. The inner walls of the four groups of first fan-shaped plates 201, second fan-shaped plates 202 and third fan-shaped plates 203 are respectively installed with first inclined wedge blocks 204, second inclined wedge blocks 205 and third inclined wedge blocks 206. One side of the four groups of first inclined wedge blocks 204, second inclined wedge blocks 205 and third inclined wedge blocks 206 is respectively provided with a first inclined wedge plate 207, second inclined wedge plate 208 and third inclined wedge plate 209. A sliding structure is provided on one side of the disc 101 to drive The four sets of first, second, and third slanted wedges 207, 208, and 209 translate, applying pressure to the first, second, and third slanted wedges 204, 205, and 206, respectively. This pressure transfer mechanism causes the first, second, and third slanted wedges 204, 205, and 206 to push the first, second, and third sector plates 201, 202, and 203, respectively, to change their positions. The sliding structure ensures that the first, second, and third sector plates 201, 202, and 203 can smoothly move upward when needed. This movement causes the highest point of the expansion and contraction cylinder 214 to change position, which in turn affects the strip wrap angle within that section. This changes the strip wrap angle within that section, independently controlling the wrap angle of each section to achieve the goal of controlling the position accuracy of the shape meter's measuring rollers and improving strip shape quality.

[0028] The sliding structure includes a second slide groove 216 and a first slide groove 211 respectively opened on both sides of the first fan plate 201 and the third fan plate 203. The second fan plate 202 is fixedly installed on both sides of the second fan plate 202. The first slider 210 is installed on both sides of the second fan plate 202, and the first slider 210 and the first slide groove 211 are slidably connected. Through the setting of the first slider 210, the first slide groove 211 and the second slide groove 216, it is ensured that the position of the second fan plate 202 can be changed.

[0029] A second slider 212 is installed on the inner wall of the disk 101, and the second slider 212 is slidably connected to the second slide groove 216. A third slider 213 is installed on the inner wall of the ring 102, and the third slider 213 is slidably connected to the first slide groove 211. Through the setting of the first slider 210, the first slide groove 211, the second slider 212, the third slider 213 and the second slide groove 216, the positions of the first fan plate 201, the second fan plate 202 and the third fan plate 203 can be changed.

[0030] The outer walls of the four groups of first sector plates 201, second sector plates 202 and third sector plates 203 are all provided with mounting grooves, and the inner cavities of the mounting grooves are all installed with pressure sensors 215, which can directly sense the pressure distribution of the strip on the measuring roller.

[0031] One side of the four groups of first inclined wedge plates 207 , second inclined wedge plates 208 and third inclined wedge plates 209 is provided with an expansion and contraction hydraulic cylinder, which controls the horizontal displacement of the first inclined wedge block 204 , second inclined wedge block 205 and third inclined wedge block 206 .

[0032] The four groups of first sector plates 201, second sector plates 202 and third sector plates 203 are slidably connected, and the four groups of first sector plates 201 and third sector plates 203 are slidably connected to the disc 101 and the ring 102 respectively, so that the highest point position of the expansion and contraction cylinder 214 can be changed.

[0033] During use, the four groups of first inclined wedge plates 207, second inclined wedge plates 208 and third inclined wedge plates 209 are driven by the expansion and contraction hydraulic cylinder to perform translational movement, so that they can apply pressure to the first inclined wedge block 204, the second inclined wedge block 205 and the third inclined wedge block 206 respectively. This pressure transmission mechanism causes the first inclined wedge block 204, the second inclined wedge block 205 and the third inclined wedge block 206 to push the first fan plate 201, the second fan plate 202 and the third fan plate 203 to change their positions respectively. Through the sliding structure, it can ensure that the first fan plate 201, the second fan plate 202 and the third fan plate 203 can move up smoothly when needed. This movement causes the highest point position of the expansion and contraction cylinder 214 to change, which in turn affects the size of the strip angle on this section, thereby changing the change of the strip angle on this section, and independently controlling the size of the angle of each section to achieve the purpose of controlling the position accuracy of the plate shape meter measuring roller and improving the strip shape quality.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
