Description

Technical Field

[0001] The invention relates to the technical field of steel rolling equipment installation, and in particular to a method for quickly adjusting the vertical position accuracy of a coiler drum. Background Art

[0002] Due to the cross-sectional shape of cold-rolled or hot-rolled steel strip, it is sometimes necessary to bend the steel into coils using a coiler immediately after rolling. This provides favorable conditions for increasing the weight of the raw material, increasing rolling speed, and reducing the temperature difference between the head and tail of the rolled piece. In addition, the rolled material is easier to transport. A coiler is a mechanical device that rolls the product into coils. In the metallurgical industry, coilers are auxiliary equipment in the steel rolling line. They are generally located after the finishing stand on hot strip mills (hot strip mills) and cold strip mills, and are installed on both sides of the mill on single-stand reversing cold strip mills. In addition, coilers can also be optionally installed in various finishing lines such as continuous pickling lines, slitting lines, annealing lines, and coating lines.

[0003] The core equipment of a coiler includes the reel (spool), and auxiliary coiling equipment (auxiliary forming equipment) including auxiliary winding rollers (forming rollers). During the coiling process, the product is primarily formed on the reel. The reel is generally driven by a motor, and the auxiliary winding rollers are generally also driven by a motor for rotation and by a fluid hydraulic cylinder for movement. These components work together to smoothly complete the coiling operation.

[0004] In actual production, the long-term operation of the reel under the action of the coiling tension will cause the coiler slide to wear and reduce its accuracy, which will cause the shaft head end of the reel to tilt toward the rolling line entrance, resulting in a large deviation between the actual center line of the reel in the direction perpendicular to the rolling line and the designed installation center line of the reel, causing the strip to deviate, coil unevenly, and even produce a unilateral wave shape, thereby affecting the coil quality of the finished product. When inspection finds that the vertical position of the reel has a large deviation, it is necessary to make timely adjustments to restore the reel center line to the designed installation center line position to ensure the vertical position accuracy of the reel and thus ensure the normal operation of the reel.

[0005] When the coiler is installed at the factory, since no other equipment has been installed on the rolling line of the unit, the vertical center line of the coiler drum can be directly adjusted by hanging the center line, swinging, etc. However, if the center line of the drum deviates after the unit is installed and put into production, the center line of the unit is blocked by the equipment and it is impossible to perform hanging measurement and adjustment. The conventional practice is to use measuring instruments outside the rolling line, and then make adjustments based on the measurement results. After the adjustment, measurement and testing are carried out again, and then adjustments are made until the adjustment is within the required accuracy range. When using this adjustment method, because the measurement and adjustment data cannot be detected and tracked in real time, repeated adjustments and measurements are required to achieve the required accuracy, resulting in long adjustment time, poor accuracy, time-consuming and labor-intensive, and affecting the efficiency and effectiveness of the drum position accuracy adjustment. Summary of the Invention

[0006] The present invention provides a method for quickly adjusting the vertical position accuracy of the reel of a coiler. When the center line of the reel deviates from the direction perpendicular to the rolling line, detection and adjustment are carried out at the end of the transmission side of the coiler (i.e., the tail end of the coiler reducer base). The vertical center line of the reel can be quickly and accurately adjusted to within the required range of installation accuracy, thereby saving time and effort, ensuring the position accuracy of the reel in the direction perpendicular to the rolling line, and solving the problem of defects such as unilateral wave shape, deviation, and uneven edges of the wound steel coil caused by the cumulative deviation of the reel.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A method for quickly adjusting the vertical position accuracy of a reel of a winder comprises the following steps:

[0009] 1) Set the vertical center line between the drum and the rolling center line as AOC, the actual center line of the coiler as A1OC1, and the designed installation center line of the coiler as A2OC2; all three center lines pass through the center point O, which is the dividing point between the drum and the reducer on the designed installation center line; the drum length is L1, and the reducer base length is L2;

[0010] 2) Using a measuring device, measure the offset B1 of the actual center line A1OC1 of the coiler at the head end of the reel shaft relative to the vertical center line AOC; that is, the deviation value between the actual center line A1OC1 of the coiler and the vertical center line AOC at the two points AA1 at the head end of the reel shaft;

[0011] 3) Calculate the offset B2 of the design installation centerline A2OC2 of the winder at the head end of the reel shaft relative to the vertical centerline AOC, that is, the deviation value between the design installation centerline A2OC2 of the winder and the vertical centerline AOC at the two points AA2 at the head end of the reel shaft, which is also the design opening value of the reel shaft head end; the design opening value is calculated as 0.05~0.15mm / m along the length direction of the reel, and the calculation formula is B2=(0.05~0.15mm / m)×L1. The calculated B2 is the range value; in actual adjustment, the middle value B2'=0.1mm / m×L1 is taken as the adjustment target value;

[0012] 4) Calculate the deviation between the actual center line A1OC1 of the coiler and the designed installation center line A2OC2 at the two points A1A2 at the end of the reel shaft, that is, A1A2 = B1 + B2';

[0013] 5) The deviation between the actual center line A1OC1 of the coiler and the designed installation center line A2OC2 at the two points C1C2 on the transmission side of the reducer is the adjustment value B3. According to the principle that the opposite sides of similar triangles are proportional, the calculation formula of B3 is obtained:

[0014] B3=(L2 / L1)×(B1+B2')=(L2 / L1)×(B1+0.1mm / m×L1)

[0015] 6) According to step 5), the adjustment amount B3 is calculated and the centerline position of the reel is adjusted.

[0016] A method for quickly adjusting the vertical position accuracy of a reel of a winder also includes step 7) review; re-measuring the opening value of the reel shaft head end; if the measured opening value is within the range of the design opening value B2 obtained in step 2), the adjustment is completed; if the measured opening value exceeds the range of the design opening value B2, repeating steps 1) to 6) until the review requirements are met.

[0017] In step 2), the measuring device is a total station.

[0018] In step 6), the specific adjustment process is as follows:

[0019] a) Use the positioning slide on the reducer base and the positioning adjustment bolts on the positioning slide to establish the adjustment center point. The positioning slide includes an inlet side positioning slide and an outlet side positioning slide. The inlet side positioning slide consists of a transmission side inlet positioning slide and an operating side inlet positioning slide, and the outlet side positioning slide consists of a transmission side outlet positioning slide and an operating side outlet positioning slide. Tighten the positioning adjustment bolts closest to the operating side on the operating side inlet positioning slide and the operating side outlet positioning slide to establish an adjustment fulcrum with O as the center point.

[0020] b) Install the dial indicator to the outer end of the reducer inlet on the transmission side. The distance between the measuring head of the dial indicator and the outer end face of the reducer inlet is less than 10mm. Set the coarse reading pointer in the dial indicator to a reading range greater than 1 and less than 2. Then adjust the fine reading pointer in the dial indicator to zero. Use the dial indicator to measure the real-time movement distance of the outer end of the reducer on the transmission side.

[0021] c) Loosen the positioning adjustment bolt on the inlet-side positioning slideway and unscrew it at least 5mm, with the positioning adjustment bolt closest to the operating side remaining stationary; then loosen the positioning adjustment bolt on the outlet-side positioning slideway, with the positioning adjustment bolt closest to the operating side remaining stationary; then rotate the positioning adjustment bolt closest to the transmission side on the transmission-side outlet positioning slideway to push one end of the reducer's transmission side toward the reducer's inlet side. The movement distance is measured and read in real time using a dial indicator; stop adjustment when the movement distance reaches adjustment amount B3;

[0022] d) Rotate the positioning adjustment bolt on the inlet-side positioning slideway loosened in step c) to move the inlet-side positioning slideway to a position where it aligns with the corresponding side of the adjusted reducer. During the movement, ensure that the fluctuation of the dial indicator detection value does not exceed 0.02 mm. Then tighten the positioning adjustment bolt on the inlet-side positioning slideway loosened in step c).

[0023] e) Loosen the positioning adjustment bolt on the outlet side positioning slide closest to the operating side, then adjust and tighten all the positioning adjustment bolts on the outlet side positioning slide to control the gap between the outlet side positioning slide and the corresponding side of the reducer within 0.1mm, and then tighten all the positioning adjustment bolts on the outlet side positioning slide.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1) By real-time detection and adjustment of data, the adjustment results can be controlled more accurately to achieve precise positioning and adjustment of the centerline position of the reel;

[0026] 2) Conventional adjustment methods require repeated measurement and adjustment, resulting in long adjustment time, multiple adjustments, low adjustment efficiency, and time-consuming and labor-intensive. However, the method described in the present invention can effectively improve the adjustment accuracy and efficiency of the roll position, and can achieve the required adjustment accuracy with a single adjustment, saving time and effort.

[0027] 3) The adjustment method of the present invention is simple and easy to implement, and can meet the needs of continuous annealing and galvanizing units for adjusting the coiler. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0033] like Figure 1 As shown, the method of the present invention for quickly adjusting the vertical position accuracy of the reel of a winder comprises the following steps:

[0034] 1) Set the vertical center line of the reel 1 perpendicular to the rolling center line as AOC, the actual center line of the coiler as A1OC1, and the designed installation center line of the coiler as A2OC2; all three center lines pass through the center point O, which is the dividing point between the reel 1 and the reducer 2 on the designed installation center line; the length of the reel 1 is L1, and the length of the reducer base is L2;

[0035] 2) Using a measuring device, measure the offset B1 of the actual center line A1OC1 of the coiler at the head end of the reel shaft relative to the vertical center line AOC; that is, the deviation value between the actual center line A1OC1 of the coiler and the vertical center line AOC at the two points AA1 at the head end of the reel shaft;

[0036] 3) Calculate the offset B2 of the design installation centerline A2OC2 of the winder at the head end of the reel shaft relative to the vertical centerline AOC, that is, the deviation value between the design installation centerline A2OC2 of the winder and the vertical centerline AOC at the two points AA2 at the head end of the reel shaft, which is also the design opening value of the reel shaft head end; the design opening value is calculated as 0.05~0.15mm / m along the length direction of the reel, and the calculation formula is B2=(0.05~0.15mm / m)×L1. The calculated B2 is the range value; in actual adjustment, the middle value B2'=0.1mm / m×L1 is taken as the adjustment target value;

[0037] 4) Calculate the deviation between the actual center line A1OC1 of the coiler and the designed installation center line A2OC2 at the two points A1A2 at the end of the reel shaft, that is, A1A2 = B1 + B2';

[0038] 5) The deviation between the actual center line A1OC1 of the coiler and the designed installation center line A2OC2 at the two points C1C2 on the transmission side of the reducer is the adjustment value B3. According to the principle that the opposite sides of similar triangles are proportional, the calculation formula of B3 is obtained:

[0039] B3=(L2 / L1)×(B1+B2')=(L2 / L1)×(B1+0.1mm / m×L1)

[0040] 7) According to step 5), the adjustment amount B3 is calculated and the centerline position of the reel is adjusted.

[0041] The method for quickly adjusting the vertical position accuracy of the winder drum described in the present invention also includes step 7) review; re-measuring the opening value of the drum shaft head end, if the measured opening value is within the range of the design opening value B2 obtained in step 2), the adjustment is completed; if the measured opening value exceeds the range of the design opening value B2, repeat steps 1) to 6) until the review requirements are met.

[0042] In step 2), the measuring device is a total station.

[0043] In step 6), the specific adjustment process is as follows:

[0044] a) Use the positioning slides on the reducer base and the positioning adjustment bolts on the positioning slides to establish the adjustment center point. The positioning slides include an inlet-side positioning slide and an outlet-side positioning slide. The inlet-side positioning slide consists of a transmission-side inlet positioning slide 41a and an operating-side inlet positioning slide 42a, and the outlet-side positioning slide consists of a transmission-side outlet positioning slide 41n and an operating-side outlet positioning slide 42b. Tighten the positioning adjustment bolts closest to the operating side on the operating-side inlet positioning slide 41b and the operating-side outlet positioning slide 42b to establish an adjustment fulcrum with O as the center point.

[0045] b) Install dial indicator 3 to the outer end of the reducer inlet on the transmission side. The distance between the measuring head of dial indicator 3 and the outer end face of the reducer inlet is less than 10 mm. Set the coarse reading pointer of dial indicator 3 to a reading range greater than 1 and less than 2. Then adjust the fine reading pointer of dial indicator 3 to zero. Use dial indicator 3 to measure the real-time movement distance of the outer end of the transmission side of reducer 2.

[0046] c) Loosen the positioning adjustment bolts on the inlet-side positioning slideway and unscrew them at least 5mm, with the one closest to the operating side remaining stationary. Then loosen the positioning adjustment bolts on the outlet-side positioning slideway, with the one closest to the operating side remaining stationary. Then, rotate the one closest to the transmission side on the transmission-side outlet positioning slideway 41a to push one end of the reducer's transmission side toward the reducer's inlet side. The distance moved is measured in real time using dial indicator 3. Stop adjustment when the distance reaches adjustment amount B3.

[0047] d) Rotate the positioning adjustment bolt on the inlet-side positioning slideway loosened in step c) to move the inlet-side positioning slideway to a position where it aligns with the corresponding side of the adjusted reducer. During the movement, ensure that the fluctuation of the dial indicator detection value does not exceed 0.02 mm. Then tighten the positioning adjustment bolt on the inlet-side positioning slideway loosened in step c).

[0048] e) Loosen the positioning adjustment bolt on the outlet side positioning slide closest to the operating side, then adjust and tighten all the positioning adjustment bolts on the outlet side positioning slide to control the gap between the outlet side positioning slide and the corresponding side of the reducer within 0.1mm, and then tighten all the positioning adjustment bolts on the outlet side positioning slide.

[0049] The method for quickly adjusting the vertical position accuracy of the reel of the winder described in the present invention adopts the principle that the opposite sides of similar triangles are proportional, such as Figure 1 As shown, the reel and reducer of the winder are considered as a whole, and the dividing point between the two, that is, the center point or reference point, is point O; the vertical center line AOC, the design installation center line A2OC2, and the actual center line A1OC1 all pass through point O, forming two similar triangles OA1A2 and OC1C2. Among them, O1 is the outer end point of the reducer's operating side inlet, and O2 is the outer end point of the reducer's operating side outlet; A, A1 and A2 are all points on the outer end face of the reel shaft head end, and C, C1 and C2 are all points on the outer end face of the reducer's transmission side. C3 is the outer end point of the reducer's transmission side inlet, and C4 is the outer end point of the reducer's transmission side outlet.

[0050] When adjusting the centerline position of the drum, first measure and calculate the deviation value of the actual centerline relative to the designed installation centerline between points A1 and A2 at the head end of the drum shaft. Then, based on the principle that the opposite sides of similar triangles are proportional, the deviation value between the actual centerline and the designed installation centerline at the transmission side of the reducer can be calculated, that is, the distance between points C1 and C2. This deviation value is also the adjustment amount that needs to be made when adjusting at the transmission side of the reducer.

[0051] During adjustment, take point O as the fulcrum and C2OA2 as the target reference line, make adjustments at one end of the transmission side of the reducer, and use the dial indicator to monitor the position change in real time to make the actual center line C1OA1 approach the designed installation center line C2OA2. When the adjustment distance reaches the adjustment amount, the actual center line and the designed installation center line coincide with each other in theory, and finally achieve the purpose of adjusting the actual center line of the reel to the position of the designed installation center line, thereby meeting the production line's requirements for the accuracy of the reel installation position.

[0052] The following examples are implemented on the premise of the technical solution of the present invention, and provide detailed implementation methods and specific operating processes, but the protection scope of the present invention is not limited to the following examples.

[0053] [Example]

[0054] like Figure 1 As shown, this embodiment takes the reel centerline adjustment of the 2# coiler at the 2150 continuous exit of a cold rolling mill as an example, and the specific process is as follows:

[0055] 1) According to the drawing, the drum length L1 = 3230mm, and the reducer base length L2 = 2350mm;

[0056] 2) Use a total station to measure the offset B1 of the actual center line A1OC1 of the reel shaft head end winder relative to the vertical center line AOC, B1 = 3.21 mm.

[0057] 3) Calculate the design opening value of the head end of the reel shaft according to the formula B2 = (0.05 ~ 0.15mm / m) × L1, B2 = (0.05 ~ 0.15mm / m) × L1 = 0.1615 ~ 0.4845mm, take the middle value B2' = 0.1mm / m × L1 = 0.323mm, and use this value as the adjustment target value.

[0058] 4) Calculate the deviation between the actual center line and the designed installation center line at the head end of the reel shaft, that is, B1+B2'=3.533mm.

[0059] 5) Calculate the adjustment amount at the transmission side of the reducer base, that is, B3 = (L2 / L1) × (B1 + B2') = (2350 / 3230) × 3.533 = 2.57 mm.

[0060] 6) The specific adjustment process is as follows:

[0061] a) Use the positioning slides on the reducer base and the positioning adjustment bolts on the positioning slides to establish the adjustment center point. The positioning slides include the transmission side inlet positioning slide, the operating side inlet positioning slide, the transmission side outlet positioning slide, and the operating side outlet positioning slide. Tighten the 1# positioning adjustment bolt closest to the operating side on the operating side inlet positioning slide, as well as the 16# positioning adjustment bolt closest to the operating side on the operating side inlet positioning slide, to establish the adjustment fulcrum with O as the center point.

[0062] b) Install a dial indicator to the outer end of the reducer inlet on the transmission side. The distance between the measuring head of the dial indicator and the outer end face of the reducer inlet is 10 mm. Set the coarse reading pointer in the dial indicator to a reading range greater than 1 and less than 2. Then adjust the fine reading pointer in the dial indicator to zero. Use the dial indicator to measure the real-time movement distance of the outer end of the reducer on the transmission side.

[0063] c) Loosen the 2#~8# positioning adjustment bolts on the reducer inlet side positioning slideway (including the reducer transmission side inlet positioning slideway and the reducer operation side inlet positioning slideway), unscrew them at least 5mm, and keep the 1# positioning adjustment bolt locked; then loosen the 9#~15# positioning adjustment bolts on the reducer outlet positioning slideway (including the reducer transmission side outlet positioning slideway and the reducer operation side outlet positioning slideway), and keep the 16# positioning adjustment bolt locked; then rotate the 9# positioning adjustment bolt in the direction of the bolt tightening, so that the reducer outlet side positioning slideway pushes one end of the reducer transmission side toward the reducer inlet side, and the moving distance is measured and read in real time using a dial indicator; stop adjusting when the moving distance reaches the adjustment amount B3 (2.57mm);

[0064] d) Rotate the 2#~8# positioning adjustment bolts on the positioning slideway on the inlet side of the reducer in the direction of bolt tightening, so that the positioning slideway on the inlet side of the reducer moves to a position that fits the corresponding side of the adjusted reducer. During the movement, ensure that the fluctuation of the dial indicator detection value does not exceed 0.02mm, and then tighten the lock nuts on the 2#~8# positioning adjustment bolts;

[0065] e) Loosen the 16# positioning adjustment bolt, then adjust and tighten the 9#~16# positioning adjustment bolts to control the gap between the positioning slide on the outlet side of the reducer and the corresponding side of the reducer within 0.1mm (measured with a feeler gauge), and then tighten the locking nut on the positioning adjustment bolt on the positioning slide on the outlet side of the reducer.

[0066] 7) Remeasure the opening value of the reel shaft head after adjustment. Using a total station to detect the actual centerline of the reel, the measurement and calculation show that the opening value of the reel shaft head end (toward the outlet) after adjustment is 0.31mm, which is basically consistent with the adjustment target value of 0.323mm and is within the design opening value range of 0.1615-0.4845mm. The adjusted reel position meets the technical requirements, and the adjustment is complete.

[0067] The measurement results of the roll position before and after adjustment in this embodiment are as follows: Figure 2 shown.

[0068] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
