Description

Technical Field

[0001] This application relates to the field of limit wheel detection technology, and more specifically, to a wear detector for steel coil guide limit wheels. Background Technology

[0002] Steel coil leveling is a crucial step in the metal sheet processing flow to ensure the accuracy of subsequent processes. In actual operation, it is necessary to ensure the stable transport of the steel coil by using limiting and correction mechanisms on both sides of the equipment, based on the dimensional parameters such as the width and thickness of the steel coil. In existing leveling equipment, several sets of limiting rollers are configured on both sides. Their core function is to constrain the transport trajectory of the steel coil and prevent the steel coil from shifting laterally due to uneven force during the leveling process.

[0003] However, because the wear position of the limit roller is relatively fixed, it is very easy to wear out grooves. The first limit roller that comes into contact with the steel coil wears the most. It is necessary to manually judge the limiting effect based on experience and then replace or grind it regularly. If the replacement is not done in time, it is easy to cause curling, which may damage the equipment in severe cases.

[0004] In view of this, we propose a wear detector for steel coil straightening limit wheel. Utility Model Content

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] Reference Figure 1 , Figure 2 and Figure 3This application discloses a wear detector for a steel coil straightening limit wheel, including a detection frame 1. A laser rangefinder 2 is installed on the inner side of the detection frame 1 to detect the wear degree of the limit wheel body 100. A moving component A3 is installed on the inner side of the detection frame 1 to drive the laser rangefinder 2 to move up and down. A connecting plate 4 is installed on the outer side of the detection frame 1 for connecting to a processing table 200. A display controller 5 is installed on the outer side of the connecting plate 4. The display controller 5 is electrically connected to the laser rangefinder 2 and is used to display the detection results of the laser rangefinder 2. A connecting line 21 is installed on the top of the laser rangefinder 2 and passes through the top of the detection frame 1. The laser rangefinder 2 is electrically connected to the display controller 5 through the connecting line 21.

[0018] When in use, the detector can be directly and permanently fixed to the outside of the processing table 200. The limit wheel body 100 is periodically inspected by the laser rangefinder 2. First, the detector is fixed to the edge of the processing table 200 by the connecting plate 4, ensuring that the detection end of the laser rangefinder 2 is facing the wheel surface of the limit wheel body 100. The display controller 5 is electrically connected to the laser rangefinder 2. The self-test signal of the laser rangefinder 2 is transmitted to the display controller 5 through the connecting cable 21. The distance from the detection end of the laser rangefinder 2 to the outside of the limit wheel body 100 is detected by the laser rangefinder 2. The laser rangefinder 2 is driven to move up and down by the moving component A3. During the inspection, the limit wheel body 100 can be used to correct the steel plate. The limit wheel body 100 rotates under the action of the steel plate, allowing the laser rangefinder 2 to perform a comprehensive inspection of the limit wheel body 100.

[0019] Reference Figure 1 and Figure 3 The inner side of the testing frame 1 is provided with a sliding groove A11, and a slider A12 is slidably arranged inside the sliding groove A11. The moving component A3 includes a connecting block 31, which is driven to rise and fall by external force. The connecting block 31 and the slider A12 are detachably connected by screws. The connecting block 31 and the laser rangefinder 2 are detachably connected by screws. A threaded ring A32 is fixedly arranged inside the connecting block 31. A threaded rod A33 is threaded inside the threaded ring A32. The threaded rod A33 is fixedly arranged at the output end of the drive motor A34. The drive motor A34 is fixedly arranged at the top of the testing frame 1.

[0020] When performing a comprehensive inspection of the limit wheel body 100, the display controller 5 controls the drive motor A34 to start. The drive motor A34 drives the threaded rod A33 to rotate, and the threaded ring A32 moves up and down along the axial direction of the threaded rod A33, thereby driving the connecting block 31 to move synchronously with the laser rangefinder 2. At this time, the slider A12 slides along the slide groove A11 to ensure that the laser rangefinder 2 moves up and down without deviation, so that the limit wheel body 100 can be fully inspected and the inspection and adaptation requirements of limit wheel bodies 100 of different specifications can be met. If the laser rangefinder 2 needs to be replaced, simply remove the connecting screws between the connecting block 31 and the slider A12, and the laser rangefinder 2. Maintenance is convenient.

[0021] Reference Figure 2 , Figure 3 and Figure 4 A movable component B6 is provided on the top of the connecting plate 4 for driving the movement of the detection frame 1. A slide groove B41 is provided on the top of the connecting plate 4. The movable component B6 includes a slider B61, which is slidably disposed inside the slide groove B41. A T-shaped plate 62 is fixedly disposed on the top of the slider B61. A threaded ring C63 is fixedly disposed on the inner side of the T-shaped plate 62. A threaded rod B64 is threaded on the inner side of the threaded ring C63. The threaded rod B64 is fixedly disposed at the output end of the drive motor B65. The drive motor B65 is fixedly disposed on the top of the connecting plate 4. A bearing plate 66 is detachably disposed on the side of the slide groove B41 away from the drive motor B65 by screws. The threaded rod B64 is rotatably disposed inside the bearing plate 66.

[0022] If it is necessary to inspect multiple limit wheel bodies 100 on both sides of the processing table 200, the spacing parameters are set on the display and controller 5, the drive motor B65 drives the threaded rod B64 to rotate, the threaded ring C63 moves along the axial direction of the threaded rod B64, and then drives the inspection frame 1 and the laser rangefinder 2 to move horizontally synchronously through the T-shaped plate 62. The slider B61 slides along the slide groove B41, and the bearing plate 66 limits the end of the threaded rod B64 to ensure smooth movement without shaking. Multiple rounds of inspection can be completed without manual handling of the inspection instrument.

[0023] Reference Figure 2 and Figure 4 An extension plate 42 is fixedly installed on the side of the connecting plate 4 near the processing table 200, and a threaded ring B43 is fixedly installed on the inner side of the connecting plate 4. A bolt 44 is threaded on the inner side of the threaded ring B43.

[0024] The extension plate 42 is attached to the edge of the processing table 200, and the bolt 44 is threaded to the threaded ring B43 so that the end of the bolt 44 is close to the outside of the processing table 200. Tightening the bolt 44 can fix the connecting plate 4 to the processing table 200, which facilitates the transfer or maintenance of the testing instrument.

[0025] In summary, when using the steel coil correction limit wheel wear detector disclosed in this application embodiment, the extension plate 42 of the connecting plate 4 is attached to the edge of the processing table 200, and the bolt 44 is tightened with the threaded engagement of the threaded ring B43 to fix the detector on the outside of the processing table 200 for a long time. Then, the power supply of the display controller 5 and the laser rangefinder 2 is turned on, and the "calibration mode" is selected through the display controller 5 to control the start of the drive motor A34, which drives the threaded rod A33 to rotate, so that the threaded ring A32 and the connecting block 31 drive the laser rangefinder 2 to rise and fall along the slide groove A11 to the detection position, collect the initial distance measurement value of the wheel surface of the limit wheel body 100 and store it as the reference data to ensure the accuracy of subsequent wear calculation. During routine inspections, there is no need to disassemble the equipment. The inspection cycle can be set directly on the display and controller 5. After the inspection is started, the drive motor B65 of the moving component B6 drives the threaded rod B64 to rotate. Through the threaded ring C63 and the T-shaped plate 62, the inspection frame 1 and the laser rangefinder 2 move horizontally along the slide rail B41 to the position of the first limit wheel body 100. At this time, the limit wheel body 100 rotates synchronously with the steel coil correction operation. The drive motor A34 is started by the display and controller 5. The drive motor A34 drives the threaded rod A33 to rotate. The threaded ring A32 moves up and down along the axial direction of the threaded rod A33, which in turn drives the connecting block 31 and the laser rangefinder 2 to move synchronously. The laser rangefinder 2 dynamically collects the distance measurement data of different points on the wheel surface. The display and controller 5 automatically calculates the wear amount by "wear amount = reference value - current value" and displays the wear amount. If the wear amount of a certain limit wheel body 100 exceeds the threshold, the display and controller 5 will immediately issue an audible and visual warning. The staff can stop the machine to grind or replace the limit wheel body 100.
