Description

Technical Field

[0001] This invention belongs to the field of stainless steel plate production and processing technology, and specifically relates to a device and method for eliminating edge burr defects in hot-rolled stainless steel. Background Technology

[0002] The production quality of stainless steel sheets includes monitoring mechanical properties and observing surface quality. In addition to these two aspects, the sides of the stainless steel sheets also need to be polished to avoid residual burrs that could affect transportation, processing, and use. Burrs are mostly caused by side cutting. Therefore, to reduce the occurrence of burr defects, it is necessary not only to polish them effectively but also to maintain the sharpness of the cutting blade to ensure that it can quickly and neatly cut away the burrs.

[0003] A search revealed a device for improving the side quality of stainless steel plates, with existing technology announcement number CN216371023U. This solution uses a cutting disc for cutting and a grinding disc for deburring. While the grinding disc removes burrs, prolonged use of the cutting disc at the source can dull it, hindering clean and precise cutting and causing pulling, thus increasing the burr formation rate. Therefore, while grinding burrs, it is crucial to maintain the cutting disc to keep it sharp at all times for efficient cutting.

[0004] Further searching revealed an existing technical document, CN214444520U, which describes an online shearing and deburring device for stainless steel plates. This device uses a cutting blade to cut the stainless steel plate and then uses a grinding wheel to grind the cut edges to remove burrs. This device shares the same problem as the first document in the search results: attention should be paid to the grinding and maintenance of the cutting blade to reduce the generation of burrs from the source. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for eliminating burr defects on the edges of hot-rolled stainless steel. The device can cut the stainless steel plate by means of an edge-cutting mechanism, and then polish and remove burrs from the cut edge of the stainless steel plate by means of a flat polishing mechanism and a side polishing mechanism. Furthermore, the edge-cutting mechanism is also provided with a cleaning mechanism and a grinding mechanism. The cleaning mechanism can effectively clean the debris stuck on the cutter and keep it clean, while the grinding mechanism can grind the cutter in real time to ensure the sharpness of the cutter, enabling it to cut quickly and reduce the generation of burrs.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An apparatus for eliminating burr defects on the edges of hot-rolled stainless steel includes a mounting plate, an adjusting mechanism, an edge-cutting mechanism, a flat polishing mechanism, and a side polishing mechanism. The adjusting mechanism, edge-cutting mechanism, flat polishing mechanism, and side polishing mechanism are mounted on the mounting plate. The edge-cutting mechanism is located at one end of the mounting plate, the side polishing mechanism at the other end, and the flat polishing mechanism between the edge-cutting mechanism and the side polishing mechanism. The adjusting mechanism is movably connected to the mounting plate for spacing adjustment. The mounting plate is mounted on a mounting frame, which is mounted on a frame for conveying stainless steel plates. The frame is equipped with conveying rollers. The mounting frame has a first slot to avoid the flat polishing mechanism and the side polishing mechanism. The edge-cutting mechanism cuts the side edges of the stainless steel plate, and then the side polishing mechanism and the flat polishing mechanism polish the cut edges of the stainless steel plate to remove burrs.

[0008] The mounting plate is provided with a through groove, a second empty groove, a second mounting groove, a first mounting groove and a guide groove from one end to the other. The mounting plate is also provided with a support shaft and a mounting bracket that is slidably connected to support the mounting plate. The second empty groove is used to avoid the transmission rollers on the frame.

[0009] The cutting mechanism includes a cutter, a cleaning mechanism, a grinding mechanism, and a second motor. The cutter has a rotating shaft that is rotatably connected to a mounting plate. A support plate is fixed to the mounting plate below the cutter, and the cutter touches the support plate. The support plate supports the stainless steel plate to be cut in conjunction with the cutter. The cleaning mechanism is fixed to one side of the cutter and includes a fixed arm, a support frame, a tension spring, a first scraper, a second scraper, and a pin. The fixed arm is fixed to the mounting plate, and the support frame is fixed to the fixed arm with bolts. The first and second scrapers are rotatably connected to the support frame through the pin to form a scissor structure. The ends of the tension spring are respectively fixed to the ends of the first and second scrapers. The tension spring pulls the first and second scrapers to rotate around the pin, causing the other ends of the first and second scrapers to press against the blade surface of the cutter to scrape away the debris adhering to the blade surface.

[0010] The grinding mechanism is located above the cutter and includes a first fixed seat, a first lead screw, a first adjusting arm, a second adjusting arm, a second fixed seat, a grinding block, and a fixed shaft. The fixed shaft has a second fixed seat and a mounting plate fixed at both ends. The second adjusting arm has a pair of hinged connections to the second fixed seat, and the grinding block is located at one end of the second adjusting arm. One end of the first adjusting arm is hinged to the second adjusting arm, and the other end is hinged to the first fixed seat. The first fixed seat is threaded to the first lead screw, one end of which is connected to a second motor, and the other end of the lead screw is rotatably connected to the second fixed seat. The second motor is fixed to the mounting plate, and its output shaft is connected to one end of the first lead screw. The first and second adjusting arms each have a pair of aligned through slots, with the first and second adjusting arms symmetrically arranged. The second motor drives the first lead screw to rotate, which in turn moves the first fixed seat up and down, thereby causing the first adjusting arm to pull the second adjusting arm to control the grinding block to be close to or away from the cutter.

[0011] The side-polishing mechanism includes a fixed frame, a mounting frame, a polishing roller, a fifth motor, a sixth motor, a third wedge block, a second lead screw, and a second spring. The fixed frame is fixed at the first mounting groove. The mounting frame has a limiting rod located in the guide groove. Fixed plates are provided on both sides of the mounting frame. The second spring is located between the fixed plates and the mounting plates to push the mounting frame to slide. A convex shaft is provided on one side of the mounting frame. The polishing roller is located inside the mounting frame and is rotatably connected to it via a rotating shaft. The fifth motor is fixed on the mounting frame and connects to and drives the polishing roller to rotate. The third wedge block is threadedly connected to the second lead screw. The third wedge block touches the convex shaft, and the end face of the third wedge block touches the side wall of the fixed frame to maintain the stability of the third wedge block. A gear is provided at the end of the second lead screw. The sixth motor is fixed on the fixed frame, and a gear is provided at the end of the sixth motor shaft, meshing with the gear at the end of the second lead screw shaft. The sixth motor drives the second lead screw to rotate, which in turn drives the third wedge block to push the mounting frame and the polishing roller to move closer to the side of the stainless steel plate. When the second lead screw reverses, the third wedge block moves away from the convex shaft, and the mounting frame is pushed away from the side of the stainless steel plate by the second spring.

[0012] The polishing mechanism includes a mounting base, a third motor, a fourth motor, a limiting ring, a polishing sleeve, a plug-in shaft, a control shaft, a second wedge block, and a first spring. The mounting base has a pair of components located in the second mounting groove. One end of the plug-in shaft is rotatably connected to the mounting base. The third motor is fixed on the mounting base and connects to and drives the plug-in shaft to rotate. The fourth motor is fixed on the mounting plate. The shaft end of the fourth motor is provided with a second bidirectional lead screw. The second bidirectional lead screw is threadedly connected to the mounting base. The fourth motor drives the second bidirectional lead screw to rotate, thereby driving the mounting base to move up and down in the second mounting groove.

[0013] One end of the plug shaft is provided with a limiting plate and a key block, and the other end of the plug shaft is provided with a first mounting hole and a second mounting hole. The inner wall of the first mounting hole is provided with a first sliding groove and a second sliding groove.

[0014] A first spring and a control shaft are disposed in a first mounting hole. One end of the control shaft is provided with a top block that contacts the first spring, and one side of the top block is provided with a conical surface. The other end of the control shaft is provided with a first wedge block, which is disposed in a second sliding groove. A pair of second wedge blocks are provided, which are inserted into and slidably connected to the insertion shaft. The second wedge blocks are provided with through holes and limiting bolts. The limiting bolts are disposed in the first sliding groove to limit the sliding distance of the second wedge blocks, so that one end of the second wedge block contacts the conical surface. The limiting bolts are inserted through the second mounting hole and rotated to fix them. The first spring pushes the top block to slide, and then pushes the second wedge block out through the conical surface. It further pushes the control shaft to insert the first wedge block into the through hole and to slide the second wedge block back into the first mounting hole, thereby realizing the sliding of the second wedge block.

[0015] The mounting plate has a guide plate on its side wall to guide the irregular side of the stainless steel plate cut by the cutting mechanism, and a collection box is provided below the guide plate to collect the cutting waste.

[0016] The polishing sleeve and the insertion shaft are inserted into each other. The limiting ring is sleeved on the insertion shaft and pushes the polishing sleeve. Then, the second wedge block restricts the sliding of the polishing sleeve.

[0017] Preferably, a push plate is provided at the other end of the control shaft to facilitate pushing the control shaft.

[0018] Preferably, the end of the plug shaft is provided with a sealing plate fixed by bolts to block the first mounting hole and prevent impurities from entering.

[0019] A method for using a device to eliminate burr defects on the edges of hot-rolled stainless steel, comprising the following specific steps:

[0020] S1: Mounting plate spacing adjustment: The stainless steel plate is conveyed forward on the frame, and then the first motor drives the first bidirectional lead screw to rotate, thereby driving the mounting plate to move to achieve opposing movement aggregation and reverse movement dispersion; thus controlling the spacing of the cutters in the edge cutting mechanism to meet the width required for stainless steel plate production, thereby meeting the cutting requirements.

[0021] S2: Stainless steel plate side cutting: Since the cutting blade touches the support plate, the stainless steel plate will drag the cutting blade to rotate as it passes between the cutting blade and the support plate, thus completing the cutting. Then, the cutting blade is cleaned by the cleaning mechanism and the cutting blade is polished by the grinding mechanism.

[0022] 1) Cleaning the sticky material on the cutting blade: The cleaning mechanism scrapes away the sticky debris on the rotating cutting blade. The first and second scrapers are pulled by a tension spring so that one end of each is in close contact with the cutting blade. At the same time, as the cutting blade rotates, the first and second scrapers scrape and clean the cutting blade.

[0023] 2) Grinding mechanism grinds the blade surface and blade edge: First, the second motor drives the first lead screw to rotate, which in turn drives the first fixed seat to move up and down, thereby driving the first adjusting arm to pull the second adjusting arm to control the grinding block to be close to the blade surface and away from the blade surface, thus achieving grinding after the blade is cleaned, ensuring the sharpness of the blade and cutting efficiency;

[0024] 3) Stainless steel trimming waste is guided to a collection box via a guide plate for collection and processing;

[0025] S3: Stainless steel plate surface polishing: The upper and lower surfaces of the cut edge of the stainless steel plate are polished by a flat polishing mechanism to remove burrs;

[0026] First, the fourth motor drives the second bidirectional lead screw to rotate, which in turn drives the mounting base to move in opposite directions, thereby causing the plug shaft and polishing sleeve to come close to the stainless steel plate surface. Then, the third motor provides power to drive the plug shaft and 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 insertion hole of the first wedge block, thereby causing the first wedge block to retract into the first mounting hole. Then, the limit ring is removed, and the polishing sleeve is pulled out. Then, the pressure on the control shaft is released, and the first spring will push the top block to slide, thereby pushing the first wedge block back to its original position through the conical surface. Then, a new polishing sleeve is inserted. The polishing sleeve pushes the wedge surface of the first wedge block and presses the first wedge block to slide. The first wedge block presses the conical surface and the top block to slide, thereby causing the first wedge block to retract into the first mounting hole. This effect can also be achieved by pressing the control shaft. Then, the limit ring is pushed in again in the same way, and the second wedge block is used to complete the replacement and installation of the polishing sleeve.

[0028] S4: Polishing the side end face of stainless steel plate: First, the sixth motor drives the second lead screw to rotate, which in turn drives the third wedge block to move. The third wedge block pushes the cam shaft and the mounting frame to move, so that the polishing roller, with the help of the second spring, fits against the side end face of the stainless steel plate. Then, the fifth motor provides power to rotate the polishing roller, completing the polishing process. When controlling the distance of the polishing roller, the second lead screw is reversed to drive the third wedge block to retract. At this time, 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 achieved efficiently.

[0029] The advantages of this invention compared to existing technologies are as follows:

[0030] 1) This device is equipped with an edge-cutting mechanism, a flat polishing mechanism, and a side polishing mechanism. The edge-cutting mechanism can cut the side of the stainless steel plate to meet production requirements. Then, the flat polishing mechanism and the side polishing mechanism polish the cut edge of the stainless steel plate to quickly remove burrs. Furthermore, the edge-cutting mechanism is also equipped with a cleaning mechanism and a grinding mechanism. The cleaning mechanism scrapes away the debris stuck to the rotating cutter blade. The tension spring pulls the first scraper and the second scraper to keep one end of them close to the cutter blade. At the same time, as the cutter rotates, the first scraper and the second scraper scrape the cutter blade to ensure the cleanliness of the cutter. In the grinding mechanism, the second motor drives the first lead screw to rotate, which in turn drives the first fixed seat to move up and down. This drives the first adjusting rod to pull the second adjusting rod to control the grinding block to be close to the cutter blade and away from the cutter blade. After the cutter is cleaned, the blade edge is ground, which can ensure the sharpness of the cutter and the cutting efficiency, and reduce the generation of burrs.

[0031] 2) The flat polishing mechanism can not only drive the insertion roller and polishing sleeve to rotate through the third motor to achieve the polishing effect on the stainless steel plate, but also quickly disassemble and replace the polishing sleeve to ensure polishing efficiency.

[0032] When the polishing effect of the polishing sleeve deteriorates and needs to be replaced, the control shaft is pushed through the insertion hole of the first wedge block, which in turn drives the first wedge block to retract into the first mounting hole. Then, the limit ring is removed, and the polishing sleeve can be pulled out quickly and conveniently. Then, the pressure on the control shaft is released, and the first spring pushes the top block to slide, which in turn pushes the first wedge block back to its original position through the conical surface. When replacing the polishing sleeve, the polishing sleeve pushes the wedge surface of the first wedge block and presses the first wedge block to slide. The first wedge block presses the conical surface and the top block to slide, which causes the first wedge block to retract into the first mounting hole. This effect can also be achieved by pressing the control shaft. Then, 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 requires pushing the polishing sleeve to complete the installation, and when disassembling, only the control shaft needs to be pushed to pull out the limit ring and the polishing sleeve. This quick and convenient method helps to ensure polishing efficiency and effect.

[0033] 3) In the side polishing mechanism, the sixth motor can drive the second lead screw to rotate, which in turn drives the third wedge block to move. The third wedge block pushes the mounting frame to move, thereby allowing the polishing roller to be finely adjusted to fit the side end face of the stainless steel plate with the help of the second spring, ensuring the polishing effect of the polishing roller on the side end face of the stainless steel.

[0066] The mounting plate 3 has a guide plate 8 on its side wall for guiding the irregular side of the stainless steel plate 9 cut by the cutting mechanism 5. A collection box 81 is provided below the guide plate 8 for collecting the cutting waste.

[0067] The polishing sleeve 65 is inserted into the insertion shaft 66. The limiting ring 64 is sleeved on the insertion shaft 66 to push the polishing sleeve 65, and then the second wedge block 68 restricts the sliding of the polishing sleeve 65.

[0068] The other end of the control shaft 67 is provided with a push plate 673 to facilitate pushing the control shaft 67.

[0069] The end of the plug shaft 66 is provided with a bolt-fixed sealing plate 664 to block the first mounting hole 663 and prevent impurities from entering.

[0070] A method for using a device to eliminate burr defects on the edges of hot-rolled stainless steel, comprising the following specific steps:

[0071] S1: Mounting plate spacing adjustment: The stainless steel plate 9 is conveyed 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 opposing movement aggregation and reverse movement dispersion; thereby controlling the spacing of the cutters 51 in the edge cutting mechanism 5 to meet the width required for the production of the stainless steel plate 9, thus meeting the cutting requirements.

[0072] S2: Stainless steel plate side cutting: 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, thereby completing the cutting. Then the cutter 51 is cleaned by the cleaning mechanism 52 and the cutter 51 is polished by the polishing mechanism 53.

[0073] 1) Cleaning the sticky material on the cutting blade surface: The cleaning mechanism 52 scrapes and cleans the sticky debris on the cutting blade surface of the rotating cutting blade 51. The tension spring 524 pulls the first scraper 525 and the second scraper 526 so that one end of the two scrapers is in close contact with the cutting blade surface of the cutting blade 51. At the same time, as the cutting blade 51 rotates, the first scraper 525 and the second scraper 526 scrape and clean the cutting blade surface of the cutting blade 51.

[0074] 2) Grinding mechanism grinds the blade surface and cutting edge of the cutter: First, the second motor 54 drives the first lead screw 532 to rotate, which in turn drives the first fixed 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 surface of the cutter 51 and away from the blade surface of the cutter 51, so that the cutter 51 is ground after cleaning, ensuring the sharpness of the cutter 51 and the cutting efficiency;

[0075] 3) Stainless steel trimming waste is guided to a collection box via a guide plate for collection and processing;

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

[0077] First, the fourth motor 63 drives the second bidirectional lead screw 631 to rotate, which in turn drives the mounting base 61 to move in opposite directions, thereby driving the plug shaft 66 and the polishing sleeve 65 to come close to the surface of the stainless steel plate 9. Then, the third motor 62 provides power to drive the plug shaft 66 and the polishing sleeve 65 to rotate, thus completing the polishing of the stainless steel plate 9.

[0078] When the polishing effect of the polishing sleeve 65 deteriorates and needs to be replaced, the control shaft 67 is pushed through the insertion hole 681 of the first wedge block 671, thereby causing the first wedge block 671 to retract into the first mounting hole 663. Then, the limiting ring 64 is removed, and the polishing sleeve 65 is pulled out. Then, the pressure on the control shaft 67 is released, and the first spring 69 pushes the top block 672 to slide, thereby pushing the first wedge block 671 back to its original position through the conical surface 6721. Then, a new polishing sleeve 65 is inserted. 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, thereby causing the first wedge block 671 to retract into the first mounting hole 663. This effect can also be achieved by pressing the control shaft 67. Then, the limiting ring 64 is pushed in again in the same way and cooperates with the second wedge block 68 to complete the replacement and installation of the polishing sleeve.

[0079] S4: Polishing the side end face of stainless steel plate: First, the sixth motor 75 drives the second lead screw 77 to rotate, which in turn drives the third wedge block 76 to move. The third wedge block 76 pushes the cam shaft 723 and the mounting frame 72 to move, so that the polishing roller 73 is in contact with 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, completing the polishing process. When controlling the distance of the polishing roller 73, the second lead screw 77 is reversed to drive the third wedge block 76 to retract. At this time, 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 achieved efficiently.
