Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: This utility model provides a technical solution for a steel plate beveling and trimming device, such as... Figures 1-6 As shown, it includes a base plate 100, a pad 200 fixed to the top surface of the base plate 100, a maintenance mechanism 300 disposed on the top surface of the pad 200, a clamping assembly 500 slidably connected to the top surface of the base plate 100, and a recycling hopper 400 disposed between the clamping assembly 500 and the pad 200. The maintenance mechanism 300 includes two brackets 310 fixed to the top surface of the pad 200, a first positioning bolt 320 that is connected through the inside of the brackets 310, a rotating column 330 that is rotatably connected to the inside of the two brackets 310, a flap 340 fixed to the side wall of the rotating column 330, two handles 350 fixed to the top surface of the flap 340, and a fixed scraping assembly 360 and a moving grinding assembly 370 that are disposed through the inside of the flap 340. By setting the fixed scraping assembly 360 and the moving grinding assembly 370 for trimming the bevel of the steel plate on the flip plate 340, the trimming angle can be flexibly adjusted to adapt to the bevel angle of the steel plate, thus improving the trimming accuracy. Then, the clamping assembly 500 with the steel plate is slidably placed close to the fixed trimming mechanism 300 for trimming, which improves the stability and convenience of the trimming operation.

[0018] Furthermore, the fixed scraping assembly 360 includes a first motor 361 disposed on the top surface of the flip plate 340, a bidirectional screw 362 connected to the rotating end of the first motor 361, and scraping and blowing components 363 respectively threadedly sleeved on the two threaded outer walls of the bidirectional screw 362. The scraping and blowing components 363 are slidably connected inside the flip plate 340, and the bidirectional screw 362 is rotatably connected to the top surface of the flip plate 340. By first flipping the flap 340 to make the scraping component 363 fit against the bevel of the steel plate, the scraping component 363, the grinding assembly 370, and the flap 340 are all at the same angle to the bevel of the steel plate. Then, the first motor 361 drives the bidirectional screw 362 to rotate, which in turn drives the two sets of scraping components 363 to move and clean the bevel. Finally, the clamping assembly 500 is moved to grind and trim the bevel of the steel plate, which improves the stability and convenience of the trimming operation.

[0019] Furthermore, the scraping component 363 includes a first sliding plate 3631 threaded onto the outer wall of the bidirectional thread, and a fixed scraper 3636 vertically fixed to the bottom surface of the first sliding plate 3631. By flipping the flap 340, the fixed scraper 3636 is made to fit against the bevel of the steel plate, thereby ensuring the inclination angle of the fixed scraper 3636 and the moving grinding assembly 370 for further cleaning and finishing. After adjusting the inclination angle of the fixed scraper 3636 and the moving grinding assembly 370, the first sliding plate 3631 is driven to slide inside the flap 340 by the bidirectional screw 362, so that the fixed scraper 3636 can be moved to scrape away residual debris on the bevel of the steel plate, avoiding interference, so as to facilitate further finishing of the bevel of the steel plate.

[0020] Furthermore, the scraping component 363 also includes an air outlet 3634 fixed to the top surface of the fixed scraper 3636, an air pump 3632 disposed on the side wall of the first slide plate 3631, an air pipe 3633 connected between the air pump 3632 and the air outlet 3634, and a side air jet head 3635 connected to the side wall of the air outlet 3634. The first slide plate 3631 is slidably connected to the inside of the flip plate 340. During the process of the fixed scraper 3636 moving to scrape away debris, the side air jet head 3635 is used to blow away the debris on the bevel of the steel plate to further ensure the cleaning and repair effect.

[0021] Furthermore, there are two side jet nozzles 3635 mirror images of the vertical centerline of the air outlet 3634, and the jet direction of the two side jet nozzles 3635 is respectively set along the bottom surface of both sides of the fixed scraper 3636. By setting the two side jet nozzles 3635 to be aligned with the bottom surface of both sides of the fixed scraper 3636, the debris can be blown out of the steel plate bevel surface when scraping debris, so as to ensure the subsequent grinding and finishing effect.

[0022] Furthermore, the scraping component 363 also includes a front jet head 3637 that is connected to one end of the air outlet 3634. The front jet head 3637 has a bent structure, and the jet direction of the front jet head 3637 is set along the bottom surface of the fixed scraper 3636 away from the first slide plate 3631. When the steel plate is moved past the bottom of the front jet head 3637, the front jet head 3637 can first blow away the debris in the middle of the steel plate bevel so that the fixed scraper 3636 can fit against the inclined surface of the steel plate bevel and ensure the positioning accuracy of the fixed scraper 3636.

[0023] Furthermore, the grinding assembly 370 includes a second motor 371 disposed on the top surface of the flip plate 340, a one-way screw 372 connected to the rotating end of the second motor 371, a first slider 373 threadedly sleeved on the outer wall of the one-way screw 372, and a grinding machine 374 fixed to the bottom surface of the first slider 373. The grinding plane of the grinding machine 374 is parallel to the bottom surface of the flip plate 340, and the first slider 373 is slidably connected inside the flip plate 340. After adjusting the inclination angle of the grinding plane of the grinding machine 374 by the flip plate 340, and after the initial cleaning by the moving fixed scraper 3636, the bevel of the steel plate is moved to fit the plane of the grinding machine 374, and the grinding machine 374 is driven to move stably by the one-way screw 372 to further grind and trim the bevel of the steel plate, thereby improving the stability and convenience of the trimming operation.

[0024] Furthermore, the clamping assembly 500 includes a pneumatic rod 550 disposed on the top surface of the base plate 100, a push plate 540 connected to the telescopic end of the pneumatic rod 550, two second support plates 530 respectively fixed to both sides of the push plate 540, rollers 560 rotatably connected to the side walls of the second support plates 530, a guide rod 570 connected to the rear wall of the second support plates 530, a first fixing plate 510 spanning and fixed to the top surfaces of the two second support plates 530, and a guide rod 570 disposed on the first fixing plate 510. The top surface of the 10 has two sets of fixed clamping components 520. The first fixed plate 510 has two storage slots 511 on the side near the pad 200. The width of the storage slots 511 is greater than the width of the fixed scraper 3636. One end of the guide rod 570 is slidably inserted into the pad 200. The steel plate is clamped on the first fixed plate 510 by the fixed clamping components 520. Then, the steel plate can be moved horizontally to trim the bevel by simply pulling the push plate 540 with the pneumatic rod 550. The horizontal trimming operation is stable and convenient.

[0025] Furthermore, the clamping component 520 includes a first support plate 523 slidably connected to the top surface of the first fixed plate 510, a second sliding plate 521 fixed to the bottom side wall of the first support plate 523, a second positioning bolt 522 threadedly connected to the inside of the second sliding plate 521, a second fixed plate 524 fixed to the top side wall of the support plate, an adjusting bolt 525 threadedly connected to the inside of the second fixed plate 524, and a clamping plate 526 rotatably connected to the bottom end of the adjusting bolt 525. One side of the clamping plate 526 is fitted against the side wall of the first support plate 523. The second sliding plate 521 is slidably fitted against the top surface of the first fixed plate 510. Two second sliders 5231 are fixed to the bottom surface of the first support plate 523. The second sliders 5231 are slidably connected to the inside of the first fixed plate 510. A limiting plate 5232 is fixed across the bottom surface of the two second sliders 5231. The limiting plate 5232 is slidably fitted against the bottom surface of the first fixed plate 510. The position of the first support plate 523 can be adjusted by sliding it on the first fixed plate 510 to adjust the protrusion position of the steel plate bevel on the first fixed plate 510 for subsequent bevel trimming. Then, the adjusting bolt 525 can be rotated to clamp the steel plate with the clamping plate 526, which improves the flexibility and stability of the steel plate positioning and clamping.

[0026] Specifically, the steel plate is clamped onto the first fixed plate 510. The pneumatic rod 550 first pulls the push plate 540, so that the bevel on the steel plate is close to the fixed scraper 3636. During the approach, the air pump 3632 is started, and the front air jet head 3637 is used to perform preliminary cleaning of the middle of the steel plate bevel. Then, the bottom surface of the fixed scraper 3636 is supported on the steel plate, and the pneumatic rod 550 pushes the push plate 540 to make the steel plate move horizontally. The fixed scraper 3636 flips together with the flip plate 340 until the bottom surface of the fixed scraper 3636 is parallel to and fits against the steel plate bevel. The first positioning bolt 320 is rotated to position and fix the rotating column 330 on the bracket 310, ensuring that the tilt angle of the flip plate 340 is the same as the tilt angle of the steel plate bevel. Then, the first motor 361 is started to drive the bidirectional screw 362 to rotate, causing the two first slide plates 3631 to move in opposite directions, and the two fixed scrapers 3636 to move in opposite directions to scrape off the residual debris on the bevel surface. At the same time, the side jet head 3635 blows the debris to the recovery hopper 400. After scraping and cleaning the debris from the bevel of the steel plate, the fixed scraper 3636 moves to align with the opening of the receiving groove 511. Then, the pneumatic rod 550 is activated to pull the push plate 540, and the fixed scraper 3636 enters the receiving groove 511. The grinding surface of the grinder 374 is in contact with the bevel of the steel plate. The second motor 371 and the grinder 374 are activated to perform translational grinding and finishing on the bevel of the steel plate. Finally, after grinding and finishing, the pneumatic rod 550 pushes the push plate 540, and the fixed scraper 3636 separates from the receiving groove 511. Then, the first motor 361 is started to drive the fixed scraper 3636 to move. At this time, the fixed scraper 3636 approaches but does not fit against the bevel of the steel plate. The fixed scraper 3636 drives the air cylinder 3634 to move, so that the side air jet head 3635 blows and cleans the bevel of the steel plate again, thereby completing the bevel finishing of the steel plate. Then, the fixed clamping part 520 is opened to take out the steel plate.
