Description

Technical Field

[0001] This invention relates to the field of stainless steel cold rolling technology, specifically to a cold rolling equipment for high-nickel stainless steel brackets with scratch detection function. Background Technology

[0002] High-nickel stainless steel is widely used in chemical, medical, and construction 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 contaminated by tiny substances generated during mechanical collisions or rolling processes, resulting in scratches. Any tiny scratch may affect its surface quality and subsequent processing performance.

[0003] The prior art CN118081525B discloses a stainless steel strip cold rolling equipment and its cold rolling method. The technical solution discloses that "This invention relates to the field of stainless steel strip cold rolling processing technology, specifically to a stainless steel strip cold rolling equipment and its cold rolling method, including a worktable and a support. A second rotating rod and a third rotating rod are rotatably connected to the support. In this invention, when the third rotating rod rotates synchronously with the second rotating rod, it can press and move a rubber block with the auger, thereby causing the connecting plate to drive the slide block to slide on the second rotating rod. Then, through the first connecting frame, the grinding wheel is pressed against the side of the stainless steel strip, allowing the grinding wheel to grind the side of the stainless steel strip. Furthermore, when the support roller contacts the stainless steel strip, it applies a reaction force to the slide block through the second connecting frame. This 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, allowing the support roller to adaptively shift according to the change in the width of the stainless steel strip, thereby ensuring the grinding quality of the grinding wheel at the edge of the steel strip."

[0004] Although the prior art has disclosed a stainless steel strip cold rolling equipment and its cold rolling method, there are still some shortcomings, including: 1. The cold rolling equipment lacks a corresponding guide part. During the cold rolling process, the stainless steel strip will shift due to uneven cold rolling force, resulting in surface scratches on the stainless steel strip during the cold rolling process, which affects the overall quality of the product.

[0005] 2. The cold rolling equipment lacks a corresponding tension adjustment part, which leads to unstable tension of the stainless steel strip during the cold rolling process. This results in situations such as the stainless steel strip breaking due to excessive tension or bending due to insufficient tension, affecting the cold rolling speed and product quality. Summary of the Invention

[0006] The purpose of this invention is to provide a cold rolling equipment for high-nickel stainless steel brackets with scratch detection function, so as to solve the problems mentioned in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cold rolling equipment for high-nickel stainless steel brackets with scratch detection function, the cold rolling equipment including a frame and a housing, the housing being located on the upper end face of the frame, a mounting frame being provided at the bottom of the housing, the mounting frame being located at the feeding point, a guiding mechanism and an adjusting mechanism being provided on the inner side of the mounting frame, the guiding mechanism being located above the adjusting mechanism, an upper roller and a lower roller being provided on one side of the mounting frame, a cleaning mechanism being provided on one side of the upper roller, and a receiving roller being provided on one side of the cleaning mechanism. The frame and chassis provide support and installation foundation for the entire cold rolling equipment, ensuring the stability of the entire equipment and preventing interference from external impurities. The guiding mechanism is used to adjust the feeding angle of the stainless steel at the feed point, ensuring that the stainless steel can be fed continuously and stably in the correct direction. The adjustment mechanism works with the tension sensor to monitor and adjust the tension of the stainless steel in real time during the cold rolling process, avoiding material breakage due to excessive tension or bending deformation due to insufficient tension. The cleaning mechanism can quickly remove the small particles and burrs generated after cold rolling, and can also remove shallow scratches on the surface of the stainless steel, ensuring that the surface finish of the stainless steel meets the process requirements. The take-up roller is used to reel in the cold-rolled stainless steel material.

[0008] The guiding mechanism includes a rotating shaft with a guide roller sleeved on it. A through groove is formed on one side of the inner wall of a mounting frame, and a mounting block is disposed within the through groove. A motor is positioned on the side of the mounting frame near the through groove, and a lead screw is mounted on the output shaft of the motor. The lead screw is threadedly connected to the mounting block. A limit rod is provided on the inner wall of the through groove, and the mounting block is slidably connected to the limit rod. The motor drives the lead screw to rotate, causing the mounting block to move horizontally along the limit rod, thereby adjusting the angle of the guide roller. This ensures that the stainless steel can flexibly change direction as needed during feeding. The guide roller is in direct contact with the stainless steel, directly adjusting the feeding direction of the stainless steel.

[0009] The mounting block has a groove on the side near the first rotating shaft, and a second rotating shaft is disposed within the groove. A first connecting block is disposed on one side of the groove, and one of the second rotating shafts is rotatably connected to the first connecting block. The end of the first connecting block near the first rotating shaft is retractable, and the retractable end of the first rotating shaft is connected to the first connecting block. The other end of the first rotating shaft is disposed of with the second connecting block. The mounting frame has a mounting groove on the other side of its inner wall, and one of the second rotating shafts is located on the inner wall of the mounting groove. The second connecting block is located within the mounting groove, and the second rotating shaft is rotatably connected to the second connecting block. The mounting block provides a mounting base for the second rotating shaft. The first and second connecting blocks support the first rotating shaft and the guide roller. The retractable module on the first connecting block ensures the stability of the connection between the guide roller and the mounting block during rotation.

[0010] The adjustment mechanism includes a cylinder one located on the upper surface of a mounting frame one. A mounting frame two is located on one side of the push rod of the cylinder one, inside the mounting frame one. Guide rails are provided on both sides of the mounting frame two, located on the upper inner wall of the mounting frame one. Support rods are provided on one side of each of the two end feet of the mounting frame two, and protrusions matching the shape of the guide rails are provided on one side of each support rod. The support rods are slidably connected to the guide rails, and an adjustment roller is provided between the two support rods. The cylinder one drives the mounting frame two to move up and down along the guide rails, thereby driving the adjustment roller and the pressing roller to move up and down, adjusting whether the adjustment roller and the pressing roller are in contact with the stainless steel surface, thereby adjusting the tension of the stainless steel surface. The guide rails limit the movement direction of the mounting frame two, and the two support rods provide a mounting base for the adjustment roller.

[0011] Each of the two support rods is equipped with a curved rod. A second motor is mounted on one side of each curved rod, and the output shaft of the second motor is connected to the rotating part of the curved rod. A pressure roller is positioned between the rotating parts of the two curved rods. An air bladder sleeve is fitted over the outer sides of the adjusting roller and the pressure roller. The two support rods provide support for the curved rods. The second motor drives the rotating part of the curved rods to rotate, thereby driving the pressure roller to rotate and adjusting whether it contacts the stainless steel surface, thus adjusting the surface tension of the stainless steel. The air bladder sleeve is used to change the contact area between the adjusting roller and the pressure roller and the stainless steel surface, enabling more rapid adjustment of the surface tension of the stainless steel.

[0012] Two cylinders are respectively installed on both sides of the upper end face of the machine casing. The push rods of the two cylinders are located inside the machine casing. A moving block is installed on one side of each push rod. Through slots are opened on both sides of the machine casing, and the two moving blocks are located in the through slots. Rails are installed on both sides of the inner wall of the through slots. Protrusions matching the shape of the rails are installed on both sides of the moving blocks. The moving blocks are slidably connected to the rails. Two main spindle motors are installed on the outer wall of the machine casing. One main spindle motor is located on the moving block, and the other main spindle motor is located below the moving block. The output shafts of the two main spindle motors are respectively connected to the upper roller and the lower roller. Multiple transition rollers are installed on the inner wall of the machine casing, and the multiple transition rollers are located on both sides of the lower roller. The two cylinders are used to drive the upper roller to move up and down, adjusting the distance between the upper roller and the lower roller, so that stainless steel of different thicknesses can be cold rolled. The two main spindle motors drive the upper roller and the lower roller to rotate in opposite directions, which can change the cold rolling speed of the stainless steel. The multiple transition rollers are used to support and transport the stainless steel. The transition rollers are driven by external motors.

[0013] The cleaning mechanism includes a mounting plate located on the inner wall of the housing. The mounting plate has a long, narrow groove. A mounting bracket three is mounted on the upper surface of the mounting plate, and a motor three is mounted on the upper surface of the mounting bracket three. A gear is mounted on the output shaft of the motor three, located inside the groove. Two movable plates are mounted on opposite sides of the inner wall of the groove, and these two movable plates are slidably connected to the mounting plate. One side of each movable plate has a toothed protrusion that matches the shape of the gear, and the gear meshes with the two movable plates. A mounting bracket four is mounted on the lower side of each of the two movable plates, and a motor four is mounted on one side of each of the two mounting bracket four. A cleaning roller is mounted on the output shaft of the motor four, and multiple sets of brushes and sandpaper are mounted on each of the two cleaning rollers. The mounting plate provides the mounting base for the cleaning mechanism. Mounting bracket three supports motor three, which drives the gear to rotate. The gear cooperates with the moving plates on both sides, causing the two moving plates to move towards each other, thereby moving the two cleaning rollers and changing the distance between the two cleaning rollers to clean stainless steel of different widths. Motor four drives the cleaning rollers on both sides to rotate. The brushes on the cleaning rollers can remove impurities and burrs from the surface of the stainless steel and the sandpaper on the other cleaning roller can remove minor scratches on the surface of the stainless steel, ensuring the quality and grade of the cold-rolled stainless steel after winding.

[0014] The receiving end of the machine casing is equipped with a receiving roller, and a motor five is installed on the outer wall of the machine casing, located on one side of the receiving roller. The motor five is used to drive the receiving roller to rotate, and the receiving roller is used to coil the cold-rolled stainless steel product.

[0015] An air pump is installed at the bottom of the chassis, located below the guide roller. The air pump is connected to the airbag sleeves on the adjusting roller and the pressing roller via pipes. A tension sensor is installed inside the guide roller. A vision sensor is installed on the upper inner wall of the chassis, located on one side of the mounting bracket. A position sensor is installed on one side of the inner wall of the chassis, located on the side of the upper roller. A CCD camera is installed on the upper inner wall of the chassis. The tension sensor, vision sensor, position sensor, and CCD camera are electrically connected to the control system. An air pump is used to inflate the air bladders on the adjusting roller and the pressing roller, thereby rapidly changing the contact area between the adjusting roller and the pressing roller and the stainless steel, and quickly adjusting the tension of the stainless steel surface. A tension sensor is used to detect the tension of the stainless steel surface, which facilitates subsequent tension adjustment. A vision sensor detects the specific position and shape of the stainless steel in the machine in real time, which facilitates the subsequent adjustment of the feeding direction of the stainless steel by the guide roller. A position sensor is used to detect the distance between the upper roller and the lower roller, which facilitates the cold rolling of stainless steel of different thicknesses. A CCD camera is used to detect the surface quality of the stainless steel after cold rolling, and to detect the location of impurities and scratches on the stainless steel surface.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention can monitor the status of stainless steel strip in real time through visual and position sensors, and the feeding direction of stainless steel strip can be adjusted by the guiding mechanism to prevent deviation, thereby further improving the stability and precision of the cold rolling process.

[0018] 2. This invention, through a tension sensor and adjustment mechanism, can monitor the tension of the stainless steel strip in real time and adjust the tension on the surface of the stainless steel strip to ensure that the stainless steel strip maintains appropriate tension during cold rolling, avoiding material breakage due to excessive tension or bending deformation caused by insufficient tension, thereby improving the reliability of the cold rolling process and product quality.

[0019] 3. The present invention can effectively remove tiny particles, burrs and minor scratches from the surface of cold-rolled stainless steel through the cleaning mechanism, further improving the surface finish of the product and meeting the requirements of high-precision processes. The multiple sets of brushes and sandpaper on the cleaning roller can be flexibly adjusted in spacing as needed to adapt to stainless steel strips of different widths. Attached Figure Description

This ensures that the stainless steel can flexibly change direction as needed during the feeding process. The guide roller 402 is in direct contact with the stainless steel, directly adjusting the feeding direction of the stainless steel.

[0033] Mounting block 405 has a groove on the side near the first rotating shaft 401, and a second rotating shaft 406 is installed in the groove.

The airbag sleeve 509 is used to change the contact area between the adjusting roller 505 and the pressure roller 508 and the stainless steel surface, enabling more rapid adjustment of the surface tension of the stainless steel.

[0036] Two cylinders 7 are respectively installed on both sides of the upper end face of the casing 2. The push rods of the two cylinders 7 are located inside the casing 2.

[0038] The receiving end of the machine housing 2 is equipped with a receiving roller 14, and a motor 13 is installed on the outer wall of the machine housing 2, located on one side of the receiving roller 14. The motor 13 is used to drive the receiving roller 14 to rotate, and the receiving roller 14 is used to coil the cold-rolled stainless steel product.

[0039] An air pump 15 is installed at the bottom of the chassis 2. The air pump 15 is located below the guide roller 402. The air pump 15 is connected to the airbag sleeve 509 on the adjusting roller 505 and the pressing roller 508 through pipes. A tension sensor is installed inside the guide roller 402. A vision sensor 16 is installed on the upper inner wall of the chassis 2. The vision sensor 16 is located on one side of the mounting bracket 3. A position sensor 17 is installed on one side of the inner wall of the chassis 2. The position sensor 17 is located on one side of the upper roller 10. A CCD camera 18 is installed on the upper inner wall of the chassis 2. The tension sensor, vision sensor 16, position sensor 17 and CCD camera 18 are electrically connected to the control system. Air pump 15 is used to fill air into the air bladder sleeve 509 on the adjusting roller 505 and the pressing roller 508, thereby rapidly changing the contact area between the adjusting roller 505 and the pressing roller 508 and the stainless steel, and can quickly adjust the tension of the stainless steel surface. Tension sensor is used to detect the tension of the stainless steel surface, which is convenient for subsequent tension adjustment. Vision sensor 16 detects the specific position and shape of the stainless steel in the machine box 2 in real time, which is convenient for the subsequent guide roller 402 to adjust the feeding direction of the stainless steel. Position sensor 17 is used to detect the distance between the upper roller 10 and the lower roller 11, which is convenient for cold rolling stainless steel of different thicknesses. CCD camera 18 is used to detect the surface quality of the stainless steel after cold rolling and detect the location of impurities and scratches on the stainless steel surface.

[0040] The working principle of this invention is as follows: When the cold rolling equipment is in use, the operator places the pre-treated stainless steel strip on the take-up roller 14. The motor 13 drives the take-up roller 14 to rotate, and the take-up roller 14 begins to wind up the stainless steel strip. The vision sensor 17 detects the thickness of the stainless steel strip. The control system controls the operation of the two cylinders 7. The two cylinders 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 cylinders 7 stop operating. The two main shaft motors 9 drive the upper roller 10 and the lower roller 11 to rotate in opposite directions, and cold rolling begins.

[0041] The vision sensor 17 detects the position information of the stainless steel strip. When the stainless steel strip is detected to be deviated, the motor 403 drives the lead screw 404 to rotate. The mounting block 405 moves horizontally under the drive of the lead screw 404. The mounting block 405 drives the connecting block 407 to move. The guide roller 402 is deviated in the opposite direction by a certain angle under the drive of the connecting block 407, adjusting the feeding direction of the stainless steel strip so that it can stably enter the cold rolling area. After the vision sensor 17 detects that the stainless steel strip is in the correct position, the motor 403 drives the lead screw 404 to rotate in the opposite direction, and the mounting block 405 returns to its original position under the drive of the lead screw 404.

[0042] The tension sensor inside the guide roller 402 detects the tension on the surface of the stainless steel strip in real time. If the tension sensor detects low tension on the surface of the stainless steel strip, the control system controls cylinder 501 to operate. Cylinder 501 drives mounting bracket 502 to move downward. Mounting bracket 502 drives adjusting roller 505 to move downward to the surface of the stainless steel strip. Motor 507 drives the rotating part of crank 506 to rotate downward, causing 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. The feeding speed of the stainless steel strip at the feed point... As the speed decreases, the tension increases. If the tension of the stainless steel strip is too low, the air pump 15 injects air into the airbag sleeve 509 through the pipe, increasing the contact area between the adjusting roller 505, the pressing roller 508, and the stainless steel strip. This increases the downward pressure exerted by the adjusting roller 505 and the pressing roller 508, slowing down the feeding speed of the stainless steel strip at the feed point and increasing the tension. If the tension of the stainless steel strip is too high, the cylinder 1 501 drives the mounting bracket 2 502 to move upward, causing the adjusting roller 505 and the pressing roller 508 to move away from the stainless steel strip. This reduces the pressure and tension on the stainless steel strip.

[0043] CCD camera 18 detects the surface of the cold-rolled stainless steel strip, identifying burrs, impurities, and scratches. The control system controls motor 1203 to operate, which drives gear 1204 to rotate. Gear 1204 drives moving plates 1205 on both sides to move towards each other. Moving plates 1205 on both sides drive cleaning rollers 1208 on both sides to move towards each other to both sides of the stainless steel strip. Motor 1207 drives cleaning rollers 1208 to rotate.
