Even minute defects can be quickly identified, greatly improving production efficiency and reducing safety risks.

Description

Technical Field

[0001] This utility model relates to the field of burr detection technology, and more specifically, to a device for detecting burrs during slitting of silicon steel coils. Background Technology

[0002] Slitting machines, also known as slitting lines, slitting machines, or stripping machines, are used to uncoil, slit, and rewind metal coils into strips of the required width. They are suitable for processing cold-rolled and hot-rolled carbon steel, silicon steel, tinplate, stainless steel, and various surface-coated metal materials. With changes in the market environment, the proportion of silicon steel coils processed from external sources exceeds 50%. As external processing increases and quality requirements upgrade, the judgment standards based on past production experience are no longer adequate for customer needs. For example, current slitting line equipment can reach a maximum speed of 200m / min during the rewinding process. This means that defects inherent in the raw materials and occasional defects occurring on the production line cannot be identified by monitoring equipment during continuous production. Only obvious defects can be distinguished by monitoring equipment. Minor defects affecting customer use cannot be detected in time due to production speed and other factors, leading to defective products being shipped out. Customers then experience defects and file claims. Furthermore, the process of personnel stopping the machine for verification poses safety hazards, with a high risk of accidental equipment restart. Weighing the silicon steel coils is also inconvenient. Therefore, we have proposed a silicon steel coil slitting burr detection device. Utility Model Content

A wing screw 14 is threaded onto the upper part of the stroboscope 11. The end of the wing screw 14 contacts the outer surface of the stroboscope 11. The stroboscope 11 can be stably installed on the mounting bracket 10 through the sleeve hole 13 and the wing screw 14.

In addition, the lifting seat 8 is provided with a screw hole that matches the screw 6 to ensure smooth transmission between the screw 6 and the lifting seat 8. Example 2

[0021] Based on Embodiment 1, as shown in Figures 1 and 2, the weighing and unwinding mechanism 2 includes a weighing scale 15 mounted on top of the trolley 1. A support base 16 is fixedly connected to the top surface of the weighing scale 15, and a support frame 17 is fixedly connected to the top surface of the support base 16. An mounting frame 18 is fixedly installed on the top surface of the support base 16, and a second reduction motor 19 is fixedly installed on the mounting frame 18. A connecting plate 20 is fixedly connected to the output shaft of the second reduction motor 19, and a support unwinding column 21 is bolted to the connecting plate 20. One end of the support unwinding column 21 is placed on the top surface of the support frame 17, and the longitudinally sheared silicon steel coil 3 is sleeved on the outside of the support unwinding column 21. A display screen 29 is fixedly installed on the outside of the support frame 17. The display screen 29 is electrically connected to the weighing scale 15, and the weight weighed by the weighing scale 15 is displayed on the display screen 29 so that the operator can control the process. Example 3

[0022] Based on Embodiments 1 and 2, as shown in Figures 1 to 3, the limiting mechanism 4 includes a stand 22 fixedly connected to the side of the trolley 1. A tilting frame 23 is rotatably connected to the top of the stand 22, and a pressing roller 24 is rotatably connected to the end of the tilting frame 23. The bottom surface of the pressing roller 24 contacts the top surface of the longitudinally sheared silicon steel coil 3, and the pressing roller 24 is used to press and limit the top of the longitudinally sheared silicon steel coil 3. The support mechanism 30 includes a mounting platform 25 fixedly connected to the inside of the stand 22. A hydraulic cylinder 26 is fixedly mounted on the top surface of the mounting platform 25. A U-shaped frame 27 is fixedly connected to the top of the hydraulic cylinder 26, and a support wheel 28 is rotatably connected to the inside of the U-shaped frame 27. The hydraulic cylinder 26, the U-shaped frame 27, and the support wheel 28 can be used to lift the tilting frame 23 upward, allowing the pressing roller 24 to be pressed upward. Release the limit on the longitudinally sheared silicon steel coil 3. In addition, the trolley 1 can be equipped with a hydraulic oil tank, hydraulic pipeline, hydraulic pump, hydraulic motor and accumulator. The hydraulic pump works to generate high pressure liquid to drive the hydraulic cylinder 26.

[0023] It should be noted that this utility model is a burr detection device for longitudinal shearing of silicon steel coils. In use, the longitudinally sheared silicon steel coil 3 is first placed on the support post 21, and then the support post 21 and the longitudinally sheared silicon steel coil 3 are hoisted to the top of the support base 16 using hoisting equipment, so that one end of the support post 21 is supported on the support frame 17. Simultaneously, the other end of the support post 21 is connected to the connecting plate 20 using bolts. At this time, the weighing scale 15 is used to weigh the longitudinally sheared silicon steel coil 3 above the support base 16, and the display screen 29 shows the data generated by the weighing scale 15. Then, the hydraulic cylinder 26 is activated to drive the U-shaped frame 27 and support wheel 28 downwards, causing the tilting frame 23 and the extrusion roller 24 to move downwards under their own weight. The extrusion roller 24 then extrudes the longitudinally sheared silicon steel coil 3. The top of the slitting coil is squeezed and limited, and then the end of the slitting silicon steel coil 3 is inserted into the slitting machine for slitting. At the same time, the first reduction motor 7 is started to drive the screw 6 to rotate. The screw 6 and the lifting seat 8 are moved by the threaded engagement between the screw 6 and the lifting seat 8, so that the laser sensor 9 on the side of the lifting seat 8 detects the silicon steel plate released from the slitting silicon steel coil 3. At this time, the two stroboscopes 11 are located above and below the silicon steel plate, respectively. Finally, as the end of the slitting silicon steel coil 3 continues to release, the height of the released silicon steel plate is detected in real time by the laser sensor 9. When the laser sensor 9 can no longer detect the silicon steel plate, the controller on the slitting line controls the first reduction motor 7 to start. The threaded engagement between the screw 6 and the lifting seat 8 drives the lifting seat 8 and the laser sensor 9 to continue to move downward, so that the laser sensor 9 can detect the silicon steel plate again, ensuring that the two stroboscopes 11 are always located above and below the silicon steel plate. In addition, the two stroboscopes 11 are used to... The top and bottom surfaces of the silicon steel sheet are photographed, and the images are transmitted to an external monitoring display screen so that staff can inspect the burrs and defects on the silicon steel sheet. The silicon steel sheet is in a state of near stillness under the action of the stroboscope 11, so the defects can be clearly displayed with the help of monitoring equipment. Even minor defects can be quickly identified, which greatly improves production efficiency, reduces safety risks, and can effectively provide video evidence in subsequent customer complaints, reducing quality losses.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
