Description

Technical Field

[0001] The invention belongs to the technical field of stainless steel plate production and processing, and particularly relates to a device and method for eliminating burr defects on the edge of hot-rolled stainless steel. Background Art

[0002] The production quality of stainless steel plates includes the monitoring of mechanical properties and the observation of surface quality. In addition to the above two, the side of the stainless steel plate needs to be polished to avoid residual burrs, which will affect transportation, processing and use. Most of the burrs are caused by side cutting. Therefore, in order to reduce the occurrence of burr defects, it is necessary not only to polish it effectively, but also to maintain the sharpness of the trimming cutter to ensure that it can be cut quickly and neatly to reduce the generation of burrs.

[0003] After searching, the prior art announcement number CN216371023U is a device for improving the quality of the side edge of a stainless steel plate. In this solution, cutting is achieved by a cutting disc, and then the burrs are removed by grinding with a grinding disc. Although the burrs can be removed by the grinding disc, the cutting disc at the source will become blunt if it works for a long time, and thus the cutting cannot be completed cleanly. Relatively, pulling will occur, thereby increasing the occurrence rate of burrs. Therefore, while grinding the burrs, attention should be paid to the maintenance of the cutting disc to keep it sharp at all times to facilitate cutting:

[0004] Further searching also revealed an online shearing and deburring device for stainless steel plates with a prior art announcement number of CN214444520U. This solution uses a cutting blade to cut the stainless steel plate, and then uses a grinding wheel to grind the cut portion of the stainless steel plate to remove burrs. This has the same problem as the first search document, and attention should be paid to the grinding and maintenance of the cutting blade to reduce the generation of burrs from the source.

[0019] A method for using a device for eliminating burr defects on the edge of hot-rolled stainless steel, the specific steps are as follows:

[0020] S1: Adjustment of the spacing between mounting plates: The stainless steel plate is transported forward on the rack, and then the first motor drives the first bidirectional lead screw to rotate, thereby driving the mounting plate to move to achieve opposite movement aggregation and reverse movement dispersion; thereby controlling the spacing between the cutters in the trimming mechanism to meet the width required for stainless steel plate production, thereby meeting the cutting requirements;

[0021] S2: Side cutting of stainless steel plate: Since the blade of the cutter touches the support plate, the stainless steel plate will drag the cutter to rotate when passing between the cutter and the support plate to complete the cutting, and then the cutter is cleaned by the cleaning mechanism and polished by the polishing mechanism;

[0022] 1) Cleaning sticky matter on the cutter surface: The cleaning mechanism is used to scrape and clean the sticky debris on the rotating cutter surface. The first scraper and the second scraper are pulled by the tension spring so that one end of the two is close to the cutter surface. At the same time, the cutter rotates to achieve the scraping and cleaning of the cutter surface by the first scraper and the second scraper;

[0023] 2) The grinding mechanism grinds the cutter surface and blade: first, the second motor drives the first screw to rotate, and then drives the first fixed seat to move up and down, thereby driving the first adjustment arm to pull the second adjustment arm to control the grinding block to be close to the cutter surface and away from the cutter surface, and then the cutter is polished after cleaning to ensure the sharpness and cutting efficiency of the cutter;

[0024] 3) The stainless steel trimming waste is guided to the collection box through the guide plate for collection and processing;

[0025] S3: Stainless steel plate flat polishing: polish the upper and lower surfaces of the stainless steel plate at the cutting edge through the flat polishing mechanism to remove burrs;

[0026] First, the fourth motor drives the second bidirectional lead screw to rotate, thereby driving the mounting seat to move in opposite directions, thereby driving the plug-in shaft and the polishing sleeve to approach the surface of the stainless steel plate, and then the third motor provides power to drive the plug-in shaft and the polishing sleeve to rotate to complete the polishing of the stainless steel plate;

[0027] When the polishing effect of the polishing sleeve deteriorates and needs to be replaced, the control shaft is pushed through the first wedge block plug-in through hole to drive the first wedge block to retreat into the first mounting hole, and then the limit ring is taken out to pull out the polishing sleeve, and then the pressure on the control shaft is released, the first spring will push the top block to slide, and then push the first wedge block to reset through the conical surface; then replace and insert a new polishing sleeve, the polishing sleeve pushes the wedge surface of the first wedge block and suppresses the first wedge block to slide, the first wedge block suppresses the conical surface and the top block to slide, and then the first wedge block retreats into the first mounting hole, and this effect can also be further achieved by suppressing the control shaft; then the limit ring is pushed in according to this method and cooperates with the second wedge block to complete the replacement and installation of the polishing sleeve:

[0028] S4: Polishing the side end face of the stainless steel plate: First, the sixth motor drives the second screw to rotate and then drives the third wedge block to move. The third wedge block pushes the cam and the mounting frame to move, so that the polishing roller fits the side end face of the stainless steel plate with the cooperation of the second spring; then the fifth motor provides power to realize the rotation of the polishing roller to complete the polishing process; when controlling the distance of the polishing roller, the second screw is reversed to drive the third wedge block to retreat, and the second spring will push the mounting frame and the polishing roller away from the stainless steel plate; through the above steps, the purpose and effect of trimming, polishing and deburring the stainless steel plate can be efficiently achieved.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1) The device is provided with a trimming mechanism, a flat polishing mechanism, and a side polishing mechanism. The trimming mechanism can cut the side of the stainless steel plate to make the stainless steel plate meet the production requirements, and then the flat polishing mechanism and the side polishing mechanism are used to perform plane polishing and side end polishing on the trimmed portion of the stainless steel plate to quickly remove burrs: Furthermore, the trimming mechanism is also provided with a cleaning mechanism and a grinding mechanism, and the cleaning mechanism is used to scrape and clean the debris stuck on the rotating cutter surface, and the first scraper and the second scraper are pulled by the tension spring so that one end of the two is close to the cutter surface. At the same time, the cutter is rotated to achieve the scraping and cleaning of the cutter surface by the first scraper and the second scraper to ensure the cleanliness of the cutter; in the grinding mechanism, the first screw rod is first driven to rotate by the second motor, and then the first fixed seat is driven to move up and down, thereby driving the first adjusting rod to pull the second adjusting rod to control the grinding block to be close to the cutter surface and away from the cutter surface, and then the blade is ground after the cutter is cleaned, which can ensure the sharpness and cutting efficiency of the cutter, ensure the sharpness of the cutter, and reduce the generation of burrs;

[0031] 2) In the flat polishing mechanism, not only can the third motor provide power to drive the plug-in roller and the polishing sleeve to rotate to achieve the polishing effect of the stainless steel plate, but the polishing sleeve can also be quickly disassembled and replaced to ensure the polishing efficiency;

[0032] When the polishing effect of the polishing sleeve deteriorates and needs to be replaced, the control shaft is pushed through the first wedge block plug-in through hole to drive the first wedge block to retreat into the first mounting hole, and then the limit ring is taken out, and then the polishing sleeve can be pulled out, which is quick and convenient, and then the pressure on the control shaft is released, the first spring will push the top block to slide, and then push the first wedge block to push and reset through the conical surface; then when replacing and inserting a new polishing sleeve, the polishing sleeve pushes the wedge surface of the first wedge block and suppresses the first wedge block to slide, the first wedge block suppresses the conical surface and the top block to slide, and then the first wedge block retreats into the first mounting hole, and this effect can also be further achieved by suppressing the control shaft; then according to this method, the limit ring is pushed in and cooperates with the second wedge block to complete the replacement and installation of the polishing sleeve: the above method only needs to push the polishing sleeve to complete the installation, and when disassembling, only the control shaft needs to be pushed to extract the limit ring and the polishing sleeve, which is quick and convenient and helps to ensure the polishing efficiency and effect;

[0033] 3) In the side-throwing mechanism, the sixth motor can drive the second screw to rotate and then drive the third wedge block to move. The third wedge block pushes the mounting frame to move, so that the polishing roller can be fine-tuned to the side end surface of the stainless steel plate with the cooperation of the second spring to ensure the polishing effect of the polishing roller on the side end surface of the stainless steel.

[0070] A method for using a device for eliminating burr defects on the edge of hot-rolled stainless steel, the specific steps are as follows:

[0071] S1: Adjustment of the spacing between the mounting plates: The stainless steel plate 9 is transported forward on the frame 1, and then the first motor 41 drives the first bidirectional lead screw 42 to rotate, thereby driving the mounting plate 3 to move to achieve opposite movement aggregation and reverse movement dispersion; thereby controlling the spacing between the cutters 51 in the trimming mechanism 5 to meet the width required by the production of the stainless steel plate 9, thereby meeting the cutting requirements;

[0072] S2: Cutting the side of the stainless steel plate: Since the blade of the cutter 51 touches the support plate 512, the stainless steel plate 9 will drag the cutter 51 to rotate when passing between the cutter 51 and the support plate 512 to complete the cutting, and then the cutter 51 is cleaned by the cleaning mechanism 52 and polished by the polishing mechanism 53;

[0073] 1) Cleaning sticky matter on the cutter surface: The cleaning mechanism 52 is used to scrape and clean the sticky debris on the rotating cutter 51. The first scraper 525 and the second scraper 526 are pulled by the tension spring 524 so that one end of the first scraper 525 and the second scraper 526 are closely attached to the cutter surface of the cutter 51. At the same time, the cutter 51 rotates to scrape and clean the cutter surface of the cutter 51 by the first scraper 525 and the second scraper 526.

[0074] 2) The grinding mechanism grinds the blade and the cutting edge of the cutter: first, the second motor 54 drives the first screw rod 532 to rotate, thereby driving the first fixing seat 531 to move up and down, thereby driving the first adjusting arm 533 to pull the second adjusting arm 534 to control the grinding block 536 to be close to the blade and away from the blade, thereby grinding the cutter 51 after cleaning, thereby ensuring the sharpness and cutting efficiency of the cutter 51;

[0075] 3) The stainless steel trimming waste is guided to the collection box through the guide plate for collection and processing;

[0076] S3: Stainless steel plate plane polishing: The upper and lower surfaces of the stainless steel plate 9 at the cutting edge position are polished by the plane polishing mechanism 6 to remove burrs;

[0077] First, the fourth motor 63 drives the second bidirectional lead screw 631 to rotate, thereby driving the mounting seat 61 to move in opposite directions, thereby driving the plug-in shaft 66 and the polishing sleeve 65 to approach the surface of the stainless steel plate 9, and then the third motor 62 provides power to drive the plug-in shaft 66 and the polishing sleeve 65 to rotate, thereby completing the polishing of the stainless steel plate 9;

[0078] When the polishing effect of the polishing sleeve 65 becomes worse and needs to be replaced, the control shaft 67 is pushed through the first wedge block 671 to insert the through hole 681, thereby driving the first wedge block 671 to retreat into the first mounting hole 663, and then the limiting ring 64 is taken out, and then the polishing sleeve 65 is pulled out, and then the pressing of the control shaft 67 is released, and the first spring 69 will push the top block 672 to slide, and then push the first wedge block 671 to reset through the conical surface 6721; then replace and insert a new polishing sleeve 65, the polishing sleeve 65 pushes the wedge surface of the first wedge block 671 and presses the first wedge block 671 to slide, the first wedge block 671 presses the conical surface 6721 and the top block 672 to slide, and then the first wedge block 671 retreats into the first mounting hole 663, and this effect can also be further achieved by pressing the control shaft 67; then the limiting ring 64 is pushed in according to this method and cooperates with the second wedge block 68 to complete the replacement and installation of the polishing sleeve:

[0079] S4: Polishing of the side end face of the stainless steel plate: First, the sixth motor 75 drives the second screw rod 77 to rotate and then drives the third wedge block 76 to move. The third wedge block 76 pushes the convex shaft 723 and the mounting frame 72 to move, so that the polishing roller 73 fits the side end face of the stainless steel plate 9 with the cooperation of the second spring 78; then the fifth motor 74 provides power to realize the rotation of the polishing roller 73 to complete the polishing process; when controlling the distance of the polishing roller 73, the second screw rod 77 is reversed to drive the third wedge block 76 to retreat, and the second spring 78 will push the mounting frame 72 and the polishing roller 73 away from the stainless steel plate 9; through the above steps, the purpose and effect of trimming, polishing and deburring the stainless steel plate 9 can be efficiently achieved.
