Description

Technical Field

[0001] The invention relates to the technical field of stainless steel cold rolling, in particular to high-nickel stainless steel cold rolling equipment for brackets with a scratch detection function. Background Art

[0002] High-nickel stainless steel is widely used in chemical, medical, construction and other fields due to its high corrosion resistance and strength. During the cold rolling process of high-nickel stainless steel, scratches are one of the common surface defects. Its surface is easily scratched by mechanical collision or tiny substances produced during rolling. Any tiny scratch may affect its surface quality and subsequent processing performance.

[0003] Prior art CN118081525B discloses a stainless steel strip cold rolling equipment and a cold rolling method thereof. The technical proposal discloses that "the present invention relates to the technical field of stainless steel strip cold rolling processing, and specifically to a stainless steel strip cold rolling equipment and a cold rolling method thereof, comprising a workbench and a support, wherein a second rotating rod and a third rotating rod are rotatably connected to the support; the present invention can squeeze and move a rubber block together with an auger when the third rotating rod and the second rotating rod rotate synchronously, so that the connecting plate drives the slide to slide on the second rotating rod, and then the grinding wheel is pressed against the side edge of the stainless steel strip through the first connecting frame, so that the grinding wheel grinds the side edge of the stainless steel strip, and when the support roller contacts the stainless steel strip, it exerts a reaction force on the slide through the second connecting frame, and the reaction force is transmitted to the rubber block. When the stainless steel strip widens, the reaction force overcomes the thrust transmitted to the rubber block by the auger, so that the support roller adaptively displaces according to the change in the width of the stainless steel strip, thereby ensuring the grinding quality of the grinding wheel on the edge of the steel strip." Although the prior art has disclosed a stainless steel strip cold rolling equipment and a cold rolling method thereof, there are still some deficiencies, including: 1. The cold rolling equipment lacks a corresponding guide part. During the cold rolling process, the stainless steel strip may deviate due to factors such as uneven cold rolling force, resulting in surface scratches on the stainless steel strip during the cold rolling process, affecting the overall quality of the product; 2. The cold rolling equipment lacks the corresponding tension adjustment part, which causes the tension of the stainless steel strip to be unstable during the cold rolling process, resulting in the stainless steel strip breaking due to excessive tension or bending due to insufficient tension, affecting the cold rolling speed and product quality of the stainless steel.

[0027] The working principle of the present invention is as follows: when the cold rolling equipment is in use, the operator places the pre-treated stainless steel strip on the receiving roller 14, the motor 5 13 drives the receiving roller 14 to rotate, the receiving roller 14 starts to reel in the stainless steel strip, the visual sensor 17 detects the thickness of the stainless steel strip, the control system controls the two cylinders 2 7 to operate, the two cylinders 2 7 drive the moving block 8 to move downward, the position sensor 16 detects the distance between the upper roller 10 and the lower roller 11, when the distance between the two rollers reaches the set value, the cylinder 2 7 stops operating, the two spindle motors 9 drive the upper roller 10 and the lower roller 11 to rotate in opposite directions, and cold rolling starts.

[0028] The visual sensor 17 detects the position information of the stainless steel strip. When it detects that the stainless steel strip is offset, the motor 403 drives the screw 404 to rotate, and the mounting block 405 moves horizontally under the drive of the screw 404. The mounting block 405 drives the connecting block 407 to move, and the guide roller 402 is offset in the opposite direction by a certain angle under the drive of the connecting block 407 to adjust the feeding direction of the stainless steel strip so that it can stably enter the cold rolling area. After the visual sensor 17 detects that the stainless steel strip is in the correct position, the motor 403 drives the screw 404 to rotate in the opposite direction, and the mounting block 405 returns to its original position under the drive of the screw 404.

[0029] The tension sensor inside the guide roller 402 detects the surface tension of the stainless steel strip in real time. If the tension sensor detects that the surface tension of the stainless steel strip is small, the control system controls the cylinder 1 501 to operate, and the cylinder 1 501 drives the mounting frame 2 502 to move downward, and the mounting frame 2 502 drives the adjusting roller 505 to move downward to the surface of the stainless steel strip. The motor 2 507 drives the rotating part of the curved rod 506 to rotate downward, driving the pressing roller 508 to contact the surface of the stainless steel strip. The adjusting roller 505 and the pressing roller 508 squeeze the stainless steel strip, and the feeding speed of the stainless steel strip at the feeding point is reduced. The speed slows down and the tension increases. If the tension of the stainless steel strip is too small, the air pump 15 injects air into the airbag sleeve 509 through the pipeline, and the contact area between the adjusting roller 505 and the pressing roller 508 and the stainless steel strip increases. The downward pressure of the adjusting roller 505 and the pressing roller 508 increases, the feeding speed of the stainless steel strip at the feed point slows down, and the tension increases; if the tension of the stainless steel strip is too large, the cylinder 1 501 drives the mounting frame 2 502 to move upward, driving the adjusting roller 505 and the pressing roller 508 away from the stainless steel strip, reducing the pressure on the stainless steel strip and reducing the tension.

[0030] The CCD camera 18 detects the surface of the stainless steel strip after cold rolling and identifies burrs, impurities and scratches on the stainless steel surface. The control system controls the operation of the motor three 1203. The motor three 1203 drives the gear 1204 to rotate. The gear 1204 drives the movable plates 1205 on both sides to move toward each other. The movable plates 1205 on both sides drive the cleaning rollers 1208 on both sides to move toward each other to the two sides of the stainless steel strip. The motor four 1207 drives the cleaning roller 1208 to rotate. The brush on the cleaning roller 1208 cleans the impurities on the surface of the stainless steel strip and the burrs on the edge. The sandpaper on the cleaning roller 1208 removes the tiny scratches on the surface of the stainless steel strip. The CCD camera 18 marks the larger scratches on the surface of the stainless steel strip for subsequent processing.
