[0048] Please refer to Figures 4-9 Trigger structure includes cylindrical rod 21, inductor 22 is fixedly connected with the rear end of cylindrical rod 21, buckle rod 23 is fixedly connected with the outer end of cylindrical rod 21 and is located in the middle part of sliding groove 18, baffle 24 is fixedly connected with the front section of cylindrical rod 21, and compression spring 25 is fixedly connected with the upper and lower parts of the rear end of baffle 24, so that trigger structure can control sensing module 10 according to the width change of bearing ring 6.Sensing module 10 is electrically connected with linear module 8, and sensing module 10 controls the extension and retraction of linear module 8, so that sensing module 10 can control the movement of linear module 8.

[0049] Please refer to Figures 3-6 The internal material of U-shaped heat-conducting block 19 is high-temperature-resistant alloy steel, and the front section of U-shaped heat-conducting block 19 is located on the same vertical line with the front end of rolling roller 17, so that U-shaped heat-conducting block 19 is not easy to be deformed by heat, and rolling roller 17 can flatten the corrugated flaws and convex points.Baffle 24 and placing groove 15 have the same cross-sectional area, and the rear end of compression spring 25 is fixedly connected with placing groove 15, so that baffle 24 can seal the cross-sectional part of placing groove 15, and compression spring 25 can limit baffle 24.

[0050] Please refer to Figures 5-7Eight sensors 22 correspond to eight induction ports 11 respectively, and the induction module 10 sends out an electric signal after the sensor 22 enters the induction port 11, so that the sensor 22 can control the induction module 10 to send out an electric signal by inserting the induction port 11. The induction module 10 is matched with the sensor 22, and a signal processor is installed inside the induction module 10, so that the induction module 10 can send out an electric signal to the linear module 8 through the signal processor.

[0051] Please refer to Figures 8-11 The sodium chloride 20 is located between the U-shaped heat-conducting block 19 and the baffle 24 and the placing groove 15, and the rolling roller 17 performs rolling work on the outer surface of the bearing ring, so that the U-shaped heat-conducting block 19 can conduct heat to the sodium chloride 20, and the gasification of the sodium chloride 20 can push the baffle 24. The metal conductor is fixedly connected to the left and right ends of the sensor 22, and the shape of the metal conductor is an arc block, so that the sensor 22 can be in electrical contact with the induction port 11 through the metal conductor.

[0052] During processing, first, the heated bearing ring 6 is placed between the first roller 4 and the second roller 5. The inner diameter of the bearing ring 6 becomes larger and the width becomes larger during the rolling processing. When the width of the bearing ring 6 becomes larger, irregular corrugated flaws or protrusions appear on the outer side of the bearing ring 6. When the corrugated flaws or protrusions contact the U-shaped heat-conducting block 19, the rolling roller 17 performs flattening operation on the flaws or protrusions on the outer side of the bearing ring 6. At the same time, the U-shaped heat-conducting block 19 conducts heat to the sodium chloride 20, the sodium chloride 20 is heated and gasified to push the baffle 24 to move backward, so that the sensor 22 is inserted into the induction port 11. The width of the bearing ring 6 continues to become larger. At this time, the flaws on the outer side of the bearing ring 6 are flattened by the eight rolling rollers 17, the eight U-shaped heat-conducting blocks 19 conduct heat to the sodium chloride 20, and the gasification of the sodium chloride 20 makes the eight sensors 22 be inserted into the induction port 11. At this time, the signal processor inside the induction module 10 sends out an electric signal to the linear module 8, and the linear module 8 controls the rolling residue device to move outward by a small distance.

[0053] After the rolling residue device moves outward by a small distance, the U-shaped heat-conducting block 19 is separated from the outer side of the bearing ring 6, the sodium chloride 20 is cooled and solidified, and the baffle 24 moves forward under the action of the compression spring 25, so that the sensor 22 is separated from the induction port 11. At this time, the signal processor inside the induction module 10 sends out a stop signal to the linear module 8, and the linear module 8 no longer controls the rolling residue device to move outward. The bearing ring 6 continues to be rolled and processed to become wider, and the above operation is repeated until the bearing ring 6 is expanded to the appropriate size. Through the flattening of the corrugated flaws on the outer side of the bearing ring by the rolling residue device and the induction triggering of the induction module 10 by the triggering structure, the flaws that appear during the processing of the bearing ring are flattened, and subsequent cutting operation is omitted, thereby improving the work efficiency.

[0054] The above merely provides the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art, according to the technical solution of the present application and the improved concept thereof, makes equivalent replacement or change within the technical range disclosed by the present application, and should be covered within the protection scope of the present application.
