Description

Technical Field

[0001] The present invention relates to the field of metallurgy, and in particular to a rod and wire production line centering calibration device and calibration method. Background Art

[0002] In the steel industry, the centering of the bar and wire production line is particularly important. The premise for the normal production of the rolling line is whether the rolling line is aligned and whether it is on the same horizontal line. If it is not on the same horizontal line, it is very easy to cause forward and backward fluctuations during rolling, resulting in problems such as steel piling on the rolling line.

[0003] Currently, the most common method for aligning a rolling mill line is to manually draw a centering line with a wooden or iron rod stuck in the middle of the rolling mill, and then adjust the line's alignment. However, this method can only align left and right, and cannot ensure that the rolling mill height is on the same level. Currently, more experienced employees rely on experience to make judgments and are unable to calibrate and adjust the horizontal alignment of the rolling mill. Whenever problems arise after rolling, they are usually raised with shims or ground down with a grinder according to the actual situation. This leads to extremely non-standard alignment of the rolling mill, making it difficult to repair over time and bringing difficulties to employees' work. They are hesitant to make adjustments and repairs, and any repairs will result in steel piles. Summary of the Invention

[0004] The present invention provides a rod and wire production line centering calibration device and calibration method to solve the problems raised in the above background technology.

[0016] S1. First, after confirming the landmark points, move the two lifting mechanisms to the corresponding docking areas. Pass the two ends of the centering line through the guide assembly and wrap them around the rotating shaft. The motor tightens the centering line to a horizontal position. Then, install the wire pulley and wire sinker accordingly.

[0017] S2. Use the lifting mechanism to push the two centering brackets up to the same level, so that the hanging wire pendant can slide on the centering line through the hanging wire pulley, and the hanging wire pendant is naturally dropped and located above the rolling line;

[0018] S3, using a ranging and altimeter device to detect the horizontal height of the landmark confirmation point and obtain a height value A;

[0019] S4. Using a distance measuring and height measuring device to detect the horizontal height of the centering line and obtain a height value B;

[0026] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0027] In the present invention, when the plumb bob is stably and naturally vertical on the centering line, whether the rolling wire is centered on the left and right is determined by observing whether the cone tip of the plumb bob is in the same position as the center of the rolling wire, and a ruler is used to measure the height between the rolling wire and the centering line to judge whether the rolling wire is horizontal in the water, thereby ensuring the centering standards and accuracy of the rolling wire, ensuring the quality of the products during work, reducing the workload of the later maintenance staff, and avoiding the production of steel piles during maintenance.

[0028] In the present invention, through the design of the lifting mechanism, the electric cylinder can drive the centering bracket to adjust the height, thereby promoting the height adjustment of the centering line, which is convenient for employees to work across the rolling line without touching the centering line, thereby reducing the trouble caused by this calibration device to the staff in the workshop.

[0029] In the present invention, brake wheels can be installed at the bottom of the base plate, so that the calibration device can be moved in the workshop, so that a single calibration device can detect rolling lines at multiple locations, reducing the cost of purchasing multiple calibration devices.

[0030] In the present invention, the motor drives the rotation of the shaft, so that the centering line can be wound and tightened on the shaft, so that the centering line can be stably in a horizontal state to ensure the accuracy of the subsequent centering calibration.

[0031] In the present invention, a scale line is set on one side of the vertical plate and an arrow is set on one side of the centering bracket, so that when the centering bracket is raised or lowered, the staff can easily observe and adjust the height, so that the two centering brackets can be adjusted to the same height to ensure the level of the centering line.

[0038] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example 1

[0040] like Figure 1-4As shown, the present invention provides a rod and wire production line centering calibration device and calibration method, including a landmark confirmation point 1, a distance and height measuring instrument device 2, two centering brackets 3, a centering line 4, a ruler 5 and a pendant 7. The top of the landmark confirmation point 1 is provided with a rolling line 6 formed by multiple guide grooves 8 connected end to end in sequence. The two centering brackets 3 are respectively located at the two ends of the rolling line 6, and the bottom ends of the two centering brackets 3 are respectively provided with a lifting mechanism, the lifting mechanism is arranged on the landmark confirmation point 1, and the top ends of the two centering brackets 3 are respectively installed with a tightening mechanism, the centering line 4 is arranged on the tightening mechanism, and is located directly above the rolling line 6. The centering line 4 can be made of nylon line or steel wire, including but not limited to the above two types. A pendant pulley 9 is movably provided on the centering line 4, and the bottom of the pendant pulley 9 is connected to the pendant 7 through a hanging line, and when the pendant 7 is automatically When vertical, the cone tip and the center of the rolling line 6 are on the same vertical plane. The centering bracket 3 is provided with a ruler 5 for measuring the distance between the centering line 4 and the rolling line 6. The distance measuring altimeter device 2 is used to respectively detect the horizontal height of the landmark confirmation point 1, the centering line 4 and the rolling line 6. The distance measuring altimeter device 2 is an existing conventional device, mainly used for measuring horizontal distance and vertical distance, and can be a laser distance measuring altimeter. This article does not make structural improvements to this existing equipment, so the distance measuring altimeter device 2 is a device that is well known and used by technical personnel in this field, and will not be elaborated in this article. The ruler 5 is not limited to the name, but is specifically a retractable ruler. The length of the ruler 5 has been adjusted, which is conducive to determining the distance value between the rolling line 6 and the centering line 4, thereby determining whether the rolling line 6 is high or low, thereby achieving the effect of centering adjustment of the rolling line 6.

[0041] Furthermore, after the centering line 4 is set on the centering bracket 3 and adjusted through the lifting mechanism, the centering line 4 is located 1-2 meters above the rolling line 6, which makes it convenient for employees to work across the rolling line 6 without touching the centering line 4, thereby reducing the trouble caused by this calibration device to the staff in the workshop.

[0042] In this embodiment, the tightening mechanism includes a motor 10 mounted on the centering bracket 3, a rotating shaft 11 connected to the output end of the motor 10, and a guide assembly connected to the centering bracket 3 and used to guide the centering line 4. The two ends of the centering line 4 pass through the guide assembly respectively and are wrapped around the corresponding rotating shaft 11. The guide assembly includes a first guide wheel 12 and a second guide wheel 13 rotatably connected to the centering bracket 3. The second guide wheel 13 is located on the inner side surface of the centering bracket 3 and corresponds to the rotating shaft 11, and the first guide wheel 12 is located on the side surface of the centering bracket 3.

[0043] Furthermore, bearing seats are installed at the top of the centering bracket 3, and the rotating shaft 11, the first guide wheel 12 and the second guide wheel 13 are installed on the bearing seats respectively. When the rotating shaft 11 is rotated by the motor 10, the centering line 4 is wound and tightened on the rotating shaft 11, so that the centering line 4 is horizontal to ensure the accuracy of the subsequent centering calibration. The control of the motor 10 is controlled by an existing external control device, and the existing control device that cooperates with the motor 10 has been used in various industries, which will not be elaborated in this article.

[0044] Furthermore, the distribution of the centering line 4 on the guide assembly is as follows: the centering line 4 is first attached to the bottom of the second guide wheel 13, then attached to the first guide wheel 12, and finally wound around the rotating shaft 11. When one end of the centering line 4 is wound around the rotating shaft 11, a wire locker can be used to lock one end of the centering line 4 to ensure the stability of the centering line 4 when it is wound.

[0045] In this embodiment, the lifting mechanism includes a base plate 14, a vertical plate 15 connected to the base plate 14, and an electric cylinder 16 installed on the top of the base plate 14. The output end of the electric cylinder 16 is connected to the bottom of the centering bracket 3, and the centering bracket 3 is slidably set on the vertical plate 15. The base plate 14 can be opened with mounting holes according to actual conditions to facilitate the passage of fastening bolts, and the base plate 14 is fixedly installed on the landmark confirmation point 1 by fastening bolts.

[0046] Furthermore, a docking area 24 is provided on the landmark confirmation point 1, and a lifting mechanism is provided in the docking area 24. When the lifting mechanism is used in a stable position, the base plate 14 is provided in the docking area 24, and the length and width of the base plate 14 are equal to the length and width of the docking area 24, so that the base plate 14 can be accurately placed along the edge of the docking area 24 when placed, and the docking area 24 is artificially sprayed with paint. Multiple docking areas 24 can be sprayed on the landmark confirmation point 1, and the sizes of the multiple docking areas 24 are equal, and the horizontal edges are on a straight line.

[0047] Furthermore, the docking area 24 can also be sprayed into two parallel lines. When the base plate 14 is placed, the two sides of the base plate 14 can cover the two lines, which is a precise placement, ensuring that the centering brackets 3 at both ends of the rolling line 6 correspond to each other, and then ensuring that the centering line 4 is a horizontal straight line, ensuring accuracy during later inspection.

[0048] In this embodiment, a sliding groove 17 is provided on the surface of the vertical plate 15 , and a guide rail 18 is slidably provided inside the sliding groove 17 . The guide rail 18 is fixedly mounted on the centering bracket 3 .

[0049] Furthermore, by utilizing the cooperation of the slide groove 17 and the guide rail 18, the stability of the centering bracket 3 can be ensured when the centering bracket 3 is lifted and slid on the vertical plate 15, and two guide rails 18 are provided to form a group. One end of a group of guide rails 18 is provided with a baffle connected to the centering bracket 3, and the baffle is mainly used to contact the top of the vertical plate 15 after the centering bracket 3 is completely lowered to ensure the stability of the centering bracket 3.

[0050] In this embodiment, a scale line 19 is provided on one side of the vertical plate 15 , and an arrow 20 is provided on one side of the centering bracket 3 , with the tip of the arrow 20 pointing to the scale line 19 .

[0051] Furthermore, by using the arrow 20 to point to the scale line 19, when the electric cylinder 16 pushes the centering bracket 3 to move, the human can determine whether the two centering brackets 3 are at the same height based on the increased value, thereby ensuring that when the two centering brackets 3 are adjusted to the same height, the centering line 4 can be kept horizontal, which is beneficial to the centering calibration of the rolling line 6 up, down, left and right.

[0052] In this embodiment, a hook 21 is fixedly connected to the surface of the centering bracket 3 , and the scale 5 is hung on the hook 21 .

[0053] Furthermore, the design of the hook 21 facilitates the storage of the ruler 5 when not in use, and also facilitates the removal of the ruler by workers when in use.

[0054] In this embodiment, the four corners of the bottom of the base plate 14 are respectively connected to the foot brake wheels 22 , and a counterweight block 23 is provided on the top of the base plate 14 .

[0055] Furthermore, the installation of the brake wheel 22 can be carried out according to the actual situation of the workshop. If the centering calibration device in this article is required at each production line, the brake wheel 22 may not be installed at the bottom of the base plate 14, and a mounting hole may be opened on the base plate 14. After the base plate 14 is docked in the docking area 24, it is fixed to the landmark confirmation point 1 by fastening bolts to ensure the long-term stable use of the calibration device; when the workshop only needs one centering calibration device, the brake wheel 22 may be installed at the bottom of the base plate 14, and a counterweight block 23 may be configured on the top of the base plate 14 to achieve stability when the base plate 14 moves, thereby realizing that a calibration device can be moved arbitrarily in the workshop, and each production line can be inspected regularly, and then a calibration device can effectively reduce the purchase cost.

[0056] Furthermore, it is necessary to consider that: when moving the calibration device, the staff can first remove the centering wire 4, and then wrap the centering wire 4 after the two calibration devices are moved to a determined position. This method is the safest, or when the staff pushes the two base plates 14 closer to each other, the motor 10 can be used to work synchronously and drive the rotating shaft 11 to rotate, prompting the rotating shaft 11 to drive the centering wire 4 to tighten. In this way, the movement of the calibration device can be achieved after the centering wire 4 is tightened, and this method has a simple operation process and does not require disassembly of the centering wire 4. Example 2

[0057] like Figure 1-4 As shown, the present invention also provides a calibration method for a rod and wire production line centering calibration device, comprising the following steps:

[0058] S1. First, after confirming the landmark confirmation point 1, the two lifting mechanisms are moved to the corresponding parking areas 24. The two ends of the centering line 4 are respectively wound around the rotating shaft 11 through the guide assembly. The centering line 4 is tightened and set horizontally by the operation of the motor 10. Then, the hanging line pulley 9 and the hanging line pendant 7 are installed accordingly.

[0059] S2. Use the lifting mechanism to push the two centering brackets 3 up to the same level, so that the hanging wire pendant 7 can slide on the centering line 4 through the hanging wire pulley 9, and the hanging wire pendant 7 is naturally dropped and located above the rolling line 6;

[0060] S3, using the ranging and altimeter device 2 to detect the horizontal height of the landmark confirmation point 1 and obtain the height value A;

[0061] S4, using the distance measuring and height measuring device 2 to detect the horizontal height of the center line 4 and obtain the height value B;

[0062] S5, using the distance measuring and height measuring device 2 to detect the horizontal height of the rolling line 6 and obtain a height value C;

[0063] S6. Calculate the standard height value D using the obtained A, B, and C. The formula is as follows:

[0064] D=A+BC;

[0065] S7, after the pendulum 7 is adjusted and moved on the centering line 4, when the pendulum 7 is stable and naturally vertical, the cone tip of the pendulum 7 is observed to be in the same position as the center of the rolling wire 6 to determine whether the rolling wire 6 is centered left and right;

[0066] S8, using the ruler 5 to measure the distance between the centering line 4 and the rolling line 6, and comparing the measured distance value with the standard height value D to determine whether the rolling line 6 is horizontally centered;

[0067] S9. Adjust the rolling line 6 according to the calibration results of the left-right centering and the horizontal centering, and perform the centering calibration again on the adjusted rolling line 6 to achieve the centering of the rolling line 6 both left-right and horizontally.

[0068] In actual use, a standard workshop bar and wire production line is taken as an example: the horizontal height of the landmark confirmation point 1 is measured to be 5265mm. When ensuring that the staff does not touch the centering line 4 when passing through the rolling line 6, the horizontal height diameter of the centering line 4 is measured to be 1530mm. Then, the actual height of the centering line 4 is calculated to be 5265mm+1530mm=6795mm, and the horizontal height diameter of the rolling line 6 is measured to be 5750mm. It is known that the standard height value of horizontal centering is 6795mm-5750mm=1045mm. Therefore, when the staff uses the ruler 5 to measure downward according to the centering line 4, if the measured height between the rolling line 6 and the centering line 4 is 1045mm, the rolling line 6 is horizontally centered. If the height value between the rolling line 6 and the centering line 4 is too large or too small, the rolling line 6 needs to be adjusted to meet the centering of the rolling line 6. This method is used to perform three-point detection on the front, middle and back of each section to ensure the centering accuracy of the rolling line 6.

[0069] When the plumb bob 7 is stable and naturally vertical, whether the rolled wire 6 is centered left and right is determined by observing whether the cone tip of the plumb bob 7 is in the same position as the center of the rolled wire 6. If the rolled wire 6 is not centered with the cone tip of the plumb bob 7, the rolled wire 6 needs to be adjusted to meet the left and right centering of the rolled wire 6. This not only ensures the centering standard specifications of the rolled wire 6, but also ensures higher accuracy and ensures the quality of the product during work.
