Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cold-rolled strip steel inspection, and in particular to an automatic surface grinding device for cold-rolled strip steel. Background Art
[0002] In the production process of cold-rolled strip steel, especially cold-rolled strip steel for the automotive manufacturing field (i.e. automotive steel plate), its surface quality directly determines the corrosion resistance, coating effect and overall aesthetics of the car body. Therefore, high-precision polishing of its surface is very important. The surface oxide scale, burrs, scratches and rolling defects must be thoroughly removed to ensure that the steel plate is evenly stressed during subsequent stamping and to avoid cracking caused by surface defects. At the same time, a flat and smooth surface can improve the adhesion of the coating, prevent the paint film from falling off and bulging, and ensure the weather resistance and service life of the car body.
[0003] Currently, automotive steel plate surface grinding often requires surface polishing to remove scale, burrs, and other defects to ensure surface quality. Cold-rolled strip surface grinding typically requires clamping the strip to prevent displacement during grinding and ensure accurate grinding.
[0004] However, the clamps of existing grinding equipment are mostly fixed or continuously pressing structures: when the clamp presses the steel strip, the contact area between it and the surface of the steel strip will be blocked, making it impossible for the grinding device to reach this area during operation; if the number of clamps is reduced or the distance between the clamps is increased to avoid blockage, the steel strip will shake during grinding due to insufficient fixing strength, affecting the grinding effect. This contradiction means that there will always be a grinding blind spot where the surface of the steel strip is pressed by the clamp, and uniform grinding of the entire surface cannot be achieved. In severe cases, defects will remain in the local unpolished areas, reducing the product quality of the cold-rolled steel strip and making it difficult to meet high-precision production requirements. Therefore, how to ensure that the steel strip is firmly fixed while eliminating the grinding blind spot caused by the obstruction of the clamp has become an urgent problem to be solved in the surface grinding technology of cold-rolled steel strip. Summary of the Invention
[0005] In order to overcome the above-mentioned defects, an embodiment of the present invention provides an automatic surface grinding device for cold-rolled strip steel, which solves the technical problem in the prior art that the position where the strip steel surface is pressed by the clamp is always in a blocked state, resulting in the grinding device being unable to process the area, and ultimately forming a grinding blind spot.

[0026] As Figures 1 to 5 As shown in the figure, it shows a cold-rolled strip steel surface automatic polishing device 2 in an embodiment of the present application, which comprises a frame body 1, the frame body 1 is provided with a polishing device 2, the polishing device 2 is used for polishing the surface of the strip steel; The frame body 1 is also provided with a limiting device 3, and the limiting device 3 is used for pressing the strip steel to avoid displacement during polishing.
[0027] The limiting device 3 includes a first pressing member 31, a second pressing member 32, and a connecting rod 33. The first pressing member 31 is swingably mounted on the frame 1, with at least one group provided, each group containing two first pressing members 31. The two first pressing members 31 are swingably connected to either side of the frame 1 and symmetrically distributed across the width of the strip. The swinging end of the first pressing member 31 faces the strip surface, and the lowest point of its swing trajectory can contact the strip surface to achieve compression.
[0028] The second clamping piece 32 is also swingably set on the frame 1, and at least one group is provided. Each group of clamping pieces 1 31 and each group of clamping pieces 2 32 are spaced apart along the length direction of the strip; each group of clamping pieces 2 32 contains at least two, and the two clamping pieces 2 32 are swingably connected to the two ends of the frame 1 respectively, and are symmetrically distributed at the two ends in the width direction of the strip, with their swinging ends facing the surface of the strip, and the lowest point of the swinging trajectory can contact the surface of the strip to achieve clamping.
[0029] The connecting rod 33 is swingably set on the frame 1 through the middle hinge shaft, and the hinge shaft is located in the middle of the frame 1 along the width direction of the strip; the two ends of the connecting rod 33 are respectively connected to the clamping piece 1 31 and the clamping piece 2 32 through a connecting rod. When the connecting rod 33 swings around its middle hinge shaft, the end thereof connected to the clamping piece 1 31 swings upward so that the clamping piece 1 31 swings and presses the strip, and at the same time, the end of the connecting rod 33 connected to the clamping piece 2 32 swings downward so that the clamping piece 2 32 swings and releases the strip.
[0030] In this embodiment, by providing a frame 1 to provide an installation base for the overall structure, the grinding device 2 can perform a grinding operation on the surface of the steel strip. In the limiting device 3, the clamping member 1 31 and the clamping member 2 32 are respectively distributed on both sides of the width direction of the steel strip, and the alternating clamping is achieved by the swing of the connecting rod 33: when the clamping member 1 31 clamps the steel strip, the clamping member 2 32 releases the steel strip, and the grinding device 2 can grind the clamping part of the clamping member 2 32; when the connecting rod 33 swings and switches to the clamping member 2 32 to clamp, the clamping member 1 31 releases the steel strip, and the grinding device 2 can grind the clamping part of the clamping member 1 31. The two sets of clamping members apply clamping force alternately to ensure that the steel strip is always in a clamped state during the grinding process, avoiding displacement of the steel strip due to insufficient clamping force.
[0031] This embodiment also includes a conveyor belt 4, which is arranged on the frame 1 along the length direction of the strip and is located directly below the grinding device 2. The conveying surface of the conveyor belt 4 contacts the lower surface of the strip and is used to convey the strip to the bottom of the grinding device 2.
[0032] The limiting device 3 also includes a first transmission assembly 34 and a second transmission assembly 35. The first transmission assembly 34 includes a lifting rod 341 and a connecting seat 342. The lifting rod 341 can be raised and lowered in the vertical direction on the frame 1. The connecting seat 342 is symmetrically arranged on both sides of the frame 1. The connecting end 3421 of the connecting seat 342 is hinged to the frame 1. The hinge end 3421 of the connecting seat 342 is hinged to the hinge point 2 372 of the swing rod 37. The hinge point 371 of the swing rod 37 is hinged to one end of the pressing member 31, and the other end of the pressing member 31 is hinged to the frame 1. After the lifting rod 341 rises, it can drive the pressing member 31 to swing around the frame 1 through the connecting seat 342 and the swing rod 37 to compress the strip steel.
[0033] The second transmission assembly 35 includes a lifting rod 351 and a connecting seat 352. The lifting rod 351 can be raised and lowered vertically on the frame 1. The connecting seat 352 is symmetrically arranged on both sides of the frame 1. The connecting end 3521 of the connecting seat 352 is hinged to the frame 1. The hinge end 3521 of the connecting seat 352 is hinged to the hinge point 382 of the swing rod 38. The hinge point 381 of the swing rod 38 is hinged to one end of the pressing member 32, and the other end of the pressing member is hinged to the frame 1. After the lifting rod 351 rises, it can drive the pressing member 32 to swing around the frame 1 through the connecting seat 352 and the swing rod 38 to compress the strip steel.
[0034] The limiting device 3 also includes a pusher 36, the telescopic end of which is connected to the middle portion of the lifting rod 1 341. When the pusher 36 is extended or retracted, it drives the lifting rod 1 341 up and down, and through the linkage of the connecting rod 33, drives the lifting rod 2 351 up and down in the opposite direction, thereby achieving alternating compression between the pressing member 1 31 and the pressing member 2 32. The pusher 36 provides power for the lifting and lowering of the lifting rod, and through the linkage of the connecting rod 33, the lifting rod 1 341 and the lifting rod 2 351 move in opposite directions, ensuring that the alternating rhythm of the pressing member 1 31 and the pressing member 2 32 matches the rhythm of conveying and grinding the steel strip, thereby improving the coordination of the device. The pusher 36 can be a cylinder, the cylinder body of which is fixed to the frame 1, and the piston rod (telescopic end) of the cylinder is arranged in the vertical direction, and the end of the piston rod is connected to the middle portion of the lifting rod 1 341. By controlling the air intake and exhaust of the cylinder, the piston rod is extended and retracted to drive the lifting rod 341 to rise or fall, and the compressibility of the gas is used to achieve smooth driving with a fast response speed, which is convenient for matching the rhythm of strip conveying and grinding.
[0035] The device also includes a moving assembly 5, through which the grinding device 2 is mounted on the frame 1. The moving assembly 5 includes a longitudinal moving rod 51, a transverse moving rod 52, and a lifting member 53. The longitudinal moving rod 51 is slidably mounted on the frame 1 in a direction parallel to the conveying direction of the conveyor belt 4; the transverse moving rod 52 is slidably mounted on the longitudinal moving rod 51 in a direction perpendicular to the conveying direction of the conveyor belt 4; the lifting member 53 is telescopically mounted on the transverse moving rod 52 in a vertical direction, and the grinding device 2 is mounted at the bottom end of the lifting member 53.
[0036] The grinding device 2 includes a connecting plate 21, a support frame 22 and a grinding piece 23: the connecting plate 21 is connected to the bottom end of the lifting member 53; one end of the support frame 22 is connected to the connecting plate 21, and the other end extends toward the conveyor belt 4; the grinding piece 23 is fixed to the end of the support frame 22 away from the connecting plate 21, and is used to contact the surface of the strip for grinding.
[0037] In the moving assembly 5, the longitudinal and transverse moving rods 51 and 52 respectively move the grinding device 2 along the length and width of the strip, while the lifting member 53 adjusts the vertical position of the grinding device 2. Together, these three components enable the grinding member 23 to cover the entire surface of the strip, avoiding the problem of missed grinding caused by fixed-position grinding. The connecting plate 21 provides a stable connection between the grinding device 2 and the lifting member 53, while the support frame 22 supports the grinding member 23, ensuring that it maintains a stable posture during operation and improving grinding accuracy.
[0038] The grinding device 2 also includes a rotating rod 24, a mounting plate 25 and a dust removal device 26: the rotating rod 24 is arranged to rotate in the vertical direction at the upper end of the support frame 22, and the rotating rod 24 is coaxial with the grinding piece 23; the mounting plate 25 is fixed on the rotating rod 24 and rotates synchronously with the rotating rod 24; the dust removal device 26 is arranged on the mounting plate 25, and is used to collect dust generated during the grinding process.
[0039] The device also includes a transmission member 27, which includes a rack 271, a gear 272, a slide 273, and a telescopic member 274. The slide 273 is mounted on the support frame 22 and slides horizontally. The rack 271 is fixed to the slide 273 and extends in the direction of its sliding. The gear 272 is fixed to the rotating rod 24 and meshes with the rack 271. The telescopic member 274 is mounted on the support frame 22, and the telescopic end of the telescopic member 274 is connected to the slide 273 to push the slide 273 to slide horizontally. When the telescopic member 274 pushes the slide 273 to slide, the rack 271 drives the gear 272 to rotate, which in turn drives the rotating rod 24 and the mounting plate 25 to rotate, causing the dust removal device 26 to rotate around the polishing member 23. The polishing head of the polishing member 23 can be a sandpaper wheel or a grinding wheel, and the choice can be made according to the material of the automotive panel and the polishing requirements.
[0040] The dust removal device 26 can be a dust hood coupled with a negative pressure line. The hood is funnel-shaped, with its opening facing the point of contact between the grinding element 23 and the steel strip. The hood is connected to a negative pressure device (such as a vacuum pump or industrial vacuum cleaner) via piping. The hood is secured to the mounting plate 25. As the rotating rod 24 rotates around the grinding element 23, its opening is always aligned with the dust generation area. Negative pressure is used to draw dust away from the source and transport it through piping to a collection device.
[0041] The dust removal device 26 rotates around the grinding piece 23 along with the rotating rod 24, and can always keep the air intake close to the source of dust generation during the grinding operation. Because dust will diffuse from the contact point between the grinding piece 23 and the steel strip during the grinding process, and the rotation trajectory of the dust removal device 26 covers the area around this contact point, the dust removal device 26 can promptly absorb the dust as soon as it is generated and before it has diffused to other locations in large quantities. This follow-up collection method reduces the floating time and diffusion range of dust in the air, improves the efficiency of dust collection, and prevents dust from adhering to other areas of the steel strip, the surface of the equipment, or diffusing into the working environment, thereby ensuring the cleanliness of the steel strip surface, the normal operation of the equipment, and the cleanliness of the working environment.
[0042] After the steel strip enters the conveyor belt, the limiting device 3 starts working. In the initial state, the swing rod is parallel to the conveyor belt, and the pressing member 1 31 and the pressing member 2 32 are both in a loose state. When the steel strip is transported to the bottom of the pressing member 1 31 and the pressing member 2 32, the pushing member 36 is activated, and the telescopic end of the pushing member 36 pushes the lifting rod 1 341 downward. The first transmission assembly 34 is activated, causing the pressing member 1 31 to press the steel strip. At the same time, under the swing action of the connecting rod 33, the lifting rod 2 351 moves upward, and the second transmission assembly 35 is activated, causing the pressing member 2 32 to be in a loose state. The grinding member 23 moves downward under the action of the lifting member 53, grinding the uncompressed portion of the steel plate. When the grinding of this area is completed, the pusher 36 is activated. The telescopic end of the pusher 36 drives the lifting rod 1 341 upward, and the first transmission assembly 34 is activated, causing the pressing member 1 31 to release the steel strip. Simultaneously, under the swinging action of the connecting rod 33, the lifting rod 2 351 moves downward, and the second transmission assembly 35 is activated, causing the pressing member 2 32 to compress the steel plate. The grinding device 2 can then grind the area near the pressing member 1 31. During the grinding process, the dust removal device 26 can rotate around the grinding member 23 to absorb dust generated during the grinding operation. It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
