Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rolling equipment technology, and more specifically, it relates to a rolling line calibration device for rolling equipment. Background Technology
[0002] Long product production lines include rolling mills, controlled rolling and cooling systems, loopers, guide channels, shears, and other rolling equipment. During production, rolled products pass through each piece of equipment sequentially. To ensure smooth movement of the rolled products, the rolling lines (steel passage lines) of each piece of equipment need to be aligned in a straight line. During daily production, rolling mills, controlled rolling and cooling systems, and loopers frequently need to be replaced, moved, and adjusted. After each replacement, movement, or adjustment, the rolling equipment needs to be horizontally adjusted using its original position as a reference point. Currently, this is done manually via visual positioning. However, with frequent equipment movement or rolling line misalignment, the rolling lines (steel passage lines) of each piece of equipment can become severely offset or misaligned horizontally, affecting equipment layout and ultimately leading to rolling failures such as steel bridging and steel stacking.
[0003] Existing technology includes a product titled "Long Product Rolling Production Line" with publication number "CN205926594U". This technology discloses a long product rolling production line, belonging to the field of bar rolling technology. The production line includes a continuous casting machine, a leveling machine, a pre-rolling emergency shear, a roughing mill, a head-cutting flying shear, an intermediate mill, a finishing mill, a sizing and cooling bed, all connected sequentially by roller conveyors. The continuous casting machine is a single-strand continuous casting machine, and the roller conveyor between the continuous casting machine and the roughing mill is a heat-insulating roller conveyor. This invention uses a single-strand continuous casting machine to cast round billets and then directly rolls them, reducing intermediate processes and heat loss, achieving headless rolling, and eliminating the need for a heating furnace, thus reducing the failure rate during production. This technology does not address the technical problems or solutions of this application. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a rolling line alignment device that is simple in structure and can effectively achieve horizontal alignment of the rolling line when the rolling equipment needs to be rearranged after replacement, movement, or adjustment, ensuring accurate positioning, realizing that all equipment of the rolling equipment is arranged in a straight line, and ensuring reliable production performance.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] This utility model is a rolling line calibration device for rolling equipment. The rolling line is arranged on the ground at the location of the rolling equipment. Multiple slots are arranged in the rolling line with gaps. Marking strips are arranged in the slots. The rolling line calibration device also includes a light source component. The light source component includes a component body. A vertical light source is set at one end of the component body and a magnet is set at the other end of the component body.
[0007] The marking strip is fixed in the slot, and the upper surface of the marking strip is flush with the ground.
[0008] The light source component is fixed in the recess at the bottom of the component body.
[0009] The magnet of the light source component is configured to be able to be attracted to the rolling equipment. When the magnet 7 is attracted to the rolling equipment, the vertical light source of the light source component is configured to be able to emit vertical light.
[0010] The rolling equipment includes a rolling mill, controlled rolling and cooling components, a looper, a guide groove, and shears.
[0011] The rolling mill, controlled rolling and cooling components, looper, guide groove, and shears of the rolling equipment are arranged in a straight line.
[0012] When the magnets of the light source components are attached to the rolling mill, the magnets of one light source component are configured to be attached to the front position of the center line of the rolling mill, and the magnets of the other light source component are configured to be attached to the rear position of the center line of the rolling mill.
[0013] When the magnet of the light source component is attracted to the rolling equipment, a marking strip is set below one of the light source components at the front of the rolling equipment, and another marking strip is set below the other light source component at the rear of the rolling equipment.
[0014] The vertical light source of the light source component is screwed into the screw hole structure inside the recess on the upper part of the component body through a threaded structure, and the vertical light source protrudes from the upper surface of the component body.
[0015] The working principle and beneficial effects of this utility model are as follows:
[0016] The rolling mill line calibration device of this utility model is structurally designed with a rolling mill line arranged on the ground at the location of the rolling mill. The rolling mill line extends along the direction of the rolling mill, controlled rolling and cooling components, looper, guide groove, and shears. Multiple slots are arranged at intervals along the rolling mill line in a straight line. A marking strip is placed in each slot, and each marking strip is positioned on the center line of the rolling mill line. Corresponding marking strips are placed at the front and rear of each rolling mill in the horizontal direction. The device also includes a light source component, comprising a component body with a vertical light source at one end and a magnet at the other end. Specific positions at the front and rear of each rolling mill can be used for magnet adsorption. After magnet adsorption, the vertical light source of the light source component shines vertically downwards. When rearranging each rolling mill after replacement, relocation, or adjustment, the magnet of one light source component is attached to the front of the centerline of the rolling mill, and the magnet of the other light source component is attached to the rear of the centerline, with both light source components aligned in a straight line. The rolling mill is then moved to its approximate position, and both light source components are activated, each emitting its light. The rolling mill is then moved further until the light source at the front of the rolling mill vertically illuminates the marker strip below it, and the light source at the rear of the rolling mill vertically illuminates the marker strip below it, with the two points aligned in a straight line. This indicates that the centerline of the rolling mill coincides with the centerline of the rolling mill's rolling line, thus correcting the rolling mill's position and ensuring proper adjustment. The position correction of the rolling mill, controlled rolling and cooling components, looper, guide groove, and shears of the rolling mill is all accomplished using the device and steps of this invention. The operation is simple, reliable, efficient, and the position correction is accurate, meeting practical requirements. Attached Figure Description

[0022] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0023] As attached Figure 1 -Appendix Figure 3As shown, this utility model is a rolling line calibration device for rolling equipment. The rolling line 1 is arranged on the ground at the location of the rolling equipment. Multiple slots 2 are arranged at intervals along the rolling line 1, and marking strips 3 are arranged within the slots 2. The rolling line calibration device also includes a light source component 4, which includes a component body 5. A vertical light source 6 is installed at one end of the component body 5, and a magnet 7 is installed at the other end. This structure addresses the shortcomings of existing technologies by proposing an improved technical solution. In the structural setup, a rolling line 1 is installed on the ground at the location of the rolling equipment. The rolling line 1 is arranged along the extension direction of the rolling mill, controlled rolling and cooling components, looper, guide groove, and shears of the rolling equipment. Multiple slots 2 are arranged at intervals along the rolling line 1, and these slots 2 are aligned in a straight line. Marking strips 3 are placed within each slot 2, and each marking strip 3 is positioned on the center line of the rolling line 1. Corresponding marking strips 3 are placed at the front and rear of each rolling equipment along the horizontal direction. The rolling line calibration device also includes a light source component 4, which comprises a component body 5. A vertical light source 6 is installed at one end of the component body 5, and a magnet 7 is installed at the other end. Specific positions at the front and rear of each rolling equipment can be used for magnet 3 adsorption. After magnet 3 adsorption, the vertical light source 6 of the light source component 4 illuminates vertically downwards. When rearranging each rolling mill after replacement, relocation, or adjustment, the magnet 7 of one light source component 4 is attached to the front of the centerline of the rolling mill, and the magnet 7 of the other light source component 4 is attached to the rear of the centerline of the rolling mill, with the two light source components 4 aligned on the same straight line. The rolling mill is then moved to its approximate arrangement position, and both light source components 4 are activated, each emitting its own light. The rolling mill is then moved until the light emitted by the front light source component 4 vertically illuminates the marker strip 3 positioned below it, and the light emitted by the rear light source component 4 vertically illuminates the marker strip 3 below it, with the two points aligned. This indicates that the centerline of the rolling mill coincides with the centerline of the rolling line 1, thus correcting the position of the rolling mill and ensuring proper positioning. The position correction of the rolling mill, controlled rolling and cooling components, looper, guide groove, and shears of the rolling mill is all accomplished using the device and steps of this invention. The operation is simple, reliable, efficient, and the position correction is accurate, meeting practical requirements. The rolling line alignment device of this utility model has a simple structure. When the rolling equipment needs to be rearranged after replacement, movement, or adjustment, it can effectively achieve horizontal alignment of the rolling line to ensure accurate positioning and realize that all equipment of the rolling equipment is arranged in a straight line, thus ensuring reliable production performance.
[0024] The marking strip 3 is fixed within the slot 2, and its upper surface is flush with the ground. With this structure, the marking strip 3 will not protrude from the ground and will not affect equipment layout or personnel passage.
[0025] The light source component 4 is fixed within a recess at the lower part of the component body 5. With this structure, the light source component is reliably installed at the lower part of the component body, facilitating the emission of a vertically downward light source after opening. When the two light sources are aligned with their corresponding marker strips, it indicates that the device position correction is complete.
[0026] The magnet 7 of the light source component 4 is configured to be able to adhere to the rolling mill. When the magnet 7 is adhered to the rolling mill, the vertical light source 6 of the light source component 4 is configured to emit vertical light. With the above structure, during the calibration of the rolling mill, the light source component is reliably adhered to the rolling mill by the magnet, and after calibration, the light source component 4 can be removed.
[0027] The rolling equipment includes a rolling mill, a controlled rolling and cooling system, a looper, a guide groove, and shears. The rolling mill, controlled rolling and cooling system, looper, guide groove, and shears are arranged in a straight line. Regardless of how the rolling mill, controlled rolling and cooling system, looper, guide groove, and shears are replaced, moved, or adjusted, after adjustment, the rolling mill, controlled rolling and cooling system, looper, guide groove, and shears must still be arranged in a straight line. The device of this invention simply and quickly solves the above problem.
[0028] When the magnet 7 of the light source component 4 is attached to the rolling mill, one magnet 7 of the light source component 4 is configured to be attached to the front position of the centerline of the rolling mill, and the other magnet 7 of the light source component 4 is configured to be attached to the rear position of the centerline of the rolling mill. When the magnet 7 of the light source component 4 is attached to the rolling mill, a marking strip 3 is placed below the front of the light source component 4 of the rolling mill, and another marking strip 3 is placed below the rear of the light source component 4. With this structure, when the rolling mill, rolling and cooling control components, loopers, guide channels, or shears of the rolling mill are replaced, moved, or adjusted, the adjustment is completed by the cooperation of the light source component and the marking strip; the corresponding light source is aligned with the corresponding marking strip to complete the calibration.
[0029] The vertical light source 6 of the light source component 4 is screwed into a threaded hole within a recess on the upper part of the component body 5 via a threaded structure, with the vertical light source 6 protruding from the upper surface of the component body 5. This structure allows for easy screwing, disassembly, and replacement of the vertical light source 6. The protruding vertical light source 6 facilitates installation and removal by screwing. The vertical light source 6 functions like a small flashlight, allowing for easy switching on and off.
[0030] The rolling mill line calibration device of this utility model is structurally configured as follows: A rolling mill line 1 is installed on the ground at the location of the rolling mill. The rolling mill line 1 is arranged along the extension direction of the rolling mill, controlled rolling and cooling components, looper, guide groove, and shears. Multiple slots 2 are arranged at intervals along the rolling mill line 1, and these slots 2 are aligned in a straight line. Marking strips 3 are arranged in each slot 2, and each marking strip 3 is positioned on the center line of the rolling mill line 1. Corresponding marking strips 3 are installed at the front and rear of each rolling mill in the horizontal direction. The rolling mill line calibration device also includes multiple light source components 4, each including a component body 5. A vertical light source 6 is installed at one end of the component body 5, and a magnet 7 is installed at the other end. Specific positions at the front and rear of each rolling mill can be used for magnet 3 adsorption. After magnet 3 adsorption, the vertical light source 6 of the light source component 4 illuminates vertically downwards. When rearranging each rolling mill after replacement, relocation, or adjustment, the magnet 7 of one light source component 4 is attached to the front of the centerline of the rolling mill, and the magnet 7 of the other light source component 4 is attached to the rear of the centerline of the rolling mill, with the two light source components 4 aligned on the same straight line. The rolling mill is then moved to its approximate arrangement position, and both light source components 4 are activated, each emitting its own light. The rolling mill is then moved until the light emitted by the front light source component 4 vertically illuminates the marker strip 3 positioned below it, and the light emitted by the rear light source component 4 vertically illuminates the marker strip 3 below it, with the two points aligned. This indicates that the centerline of the rolling mill coincides with the centerline of the rolling line 1, thus correcting the position of the rolling mill and ensuring proper positioning. The position correction of the rolling mill, controlled rolling and cooling components, looper, guide groove, and shears of the rolling mill is all accomplished using the device and steps of this invention. The operation is simple, reliable, efficient, and the position correction is accurate, meeting practical requirements.
