Description

Technical Field

[0001] The present invention belongs to the technical field of ship plate processing, and specifically relates to a plate cutting device for ship plate processing. Background Art

[0002] A ship is a general term for various vessels. A ship is a means of transportation that can navigate or berth in water areas for transportation or operations. It has different technical performances, equipment, and structural forms according to different usage requirements. A ship is a man-made means of transportation mainly operating in water, including an accommodation space, a support structure, and a drainage structure inside, and has a propulsion system using external or self-supplied energy. Its shape is generally a streamlined envelope conducive to overcoming fluid resistance. The materials have been continuously updated with the progress of science and technology. In the early days, natural materials such as wood, bamboo, and hemp were used, and in modern times, steel, as well as aluminum, fiberglass, acrylic, and various composite materials are mostly used. In the production and manufacturing process of ships, cutting devices are required to cut various plates.

[0003] In the prior art, during the cutting process of ship plates, few devices limit the plates, so that the plates are prone to shift during the cutting process, affecting the cutting quality. And after the plates are cut, the cut plates are directly allowed to fall and stack randomly, resulting in the plates being prone to shift or flip during the blanking process, making the stacking not neat enough, affecting subsequent use, and there is also a certain probability of phenomena such as tipping over during the stacking process, resulting in a chaotic working environment and affecting the work process.

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 - Figure 10As shown in the figure, a plate cutting device for ship plate processing includes a first processing table 1 and a second processing table 2. The left side wall of the second processing table 2 is fixedly connected to the right side wall of the first processing table 1, and the left inner part of the second processing table 2 is hollow-designed. This hollow design is a blanking groove for cutting the plate, so that the cut ship plate can fall smoothly at the blanking groove, and then it is convenient for collection and sorting. A limited-displacement feeding mechanism 3 is arranged on the upper surface of the first processing table 1. The limited-displacement feeding mechanism 3 includes a first motor 301, and the first motor 301 is arranged on the left outer wall of the first processing table 1 through a motor base. A first sprocket 302 is arranged on the circumferential surface of the power output end of the first motor 301. The first sprocket 302 is connected to a second sprocket 303 through a chain drive. And there are two second sprockets 303. A first threaded rod 304 is arranged on the right side of each of the two second sprockets 303. A first moving block 305 is threadedly connected to the circumferential surface of each of the two first threaded rods 304. A push plate 306 is arranged between the two first moving blocks 305, and the lower end of the push plate 306 does not contact the upper surface of the first processing table 1. The lower ends of the two first moving blocks 305 are both abutted against a first fixed installation table 307. The two first fixed installation tables 307 are respectively arranged at the front and rear ends of the upper surface of the first processing table 1. An electric telescopic rod 308 is arranged in the middle of the outside of each of the two first fixed installation tables 307. The telescopic ends of the two electric telescopic rods 308 respectively penetrate through the corresponding first fixed installation tables 307 and are fixedly connected to a moving frame 309. A limiting guide roller 310 is rotatably installed in each of the two moving frames 309, and one side of the limiting guide roller 310 protrudes outside the moving frame 309. An installation groove is opened in the upper end inside the first processing table 1, and a bottom guide roller 13 is rotatably installed in the installation groove. The upper end of the bottom guide roller 13 does not contact the lower end of the push plate 306, and the push plate 306 does not contact the bottom guide roller 13, so that when the push plate 306 moves horizontally left and right, it will not frictionally collide with the bottom guide roller 13, and thus the bottom guide roller 13 is prevented from being damaged by collision;

[0031] It should be noted that the ship plate to be cut needs other lifting equipment or transfer manipulators and other equipment to lift it above the first processing table 1, then place the plate on the upper surface of the first processing table 1, and then the two electric telescopic rods 308 drive the two moving frames 309 to approach the ship plate and clamp and limit its front and rear sides. And because of the setting of the limiting guide roller 310 and the bottom guide roller 13 inside the moving frame 309, while the plate can be limited, it does not affect the horizontal left and right movement of the plate. After that, when the push plate 306 moves to the right, the ship plate can be gradually moved to the right.

[0032] The upper surface of the processing table 2 is provided with a laser cutting mechanism 4, which includes a fixed mounting table 2 401, and two fixed mounting tables 2 401 are provided and are respectively arranged at the front and rear ends of the upper surface of the processing table 2 2, and the front and rear sides of the lower end of the mounting frame 701 are respectively arranged at the right end of the upper surface of the two fixed mounting tables 2 401, and the right outer walls of the two fixed mounting tables 2 401 are respectively provided with motors 2 402, and the power output ends of the two motors 2 402 are both transmission-connected with threaded rods 2 403, and the circumferential surfaces of the two threaded rods 2 403 are both threadedly connected with mobile racks 404, and the middle of the upper ends of the two mobile racks 404 is fixedly installed with a mounting plate 405, a motor 3 406 is arranged on the front of the mounting plate 405, a threaded rod 3 407 is transmission-connected to the power output end of the motor 3 406, a moving platform 408 is threadedly connected to the circumferential surface of the threaded rod 3 407, a lifting cylinder 1 409 is arranged on the upper surface of the moving platform 408, a lower end of the lifting cylinder 1 409 penetrates the moving platform 408 and is provided with a laser cutting head 410, the laser cutting mechanism 4 can drive the laser cutting head 410 to move horizontally left and right and forward and backward, and then the laser cutting head 410 can be moved horizontally left and right to any point above the blanking chute, and then the ship plate can be cut off after the forward and backward horizontal movement;

[0033] The processing table 2 is provided with a lifting mechanism 5 and a discharging mechanism 7 inside. The lifting mechanism 5 includes a motor 4 501, and two groups of motors 4 501 are symmetrically arranged on the left and right. The power output ends of the two groups of motors 4 501 are both connected to the spur gear 1 502 by transmission. One side of the two spur gears 1 502 is meshed with the spur gear 2 503. The middle of the two spur gears 2 503 is provided with a threaded rod 4 504. The upper ends of the two threaded rods 4 504 are respectively connected to the threaded rods through the synchronous belt mechanism 505. The threaded rod 506 and the threaded rod 6 507, wherein the synchronous belt mechanism 505 is a prior art, so it will not be described in detail, the circumferential surfaces of the lower ends of the threaded rod 4 504, the threaded rod 506 and the threaded rod 6 507 are all threadedly connected with lifting plates 508, and three groups of lifting plates 508 are provided, and the upper ends of the three groups of lifting plates 508 are placed with trays 6, wherein the upper surface of the tray 6 is provided with a soft material such as rubber, so that when the plate falls on the surface of the tray 6, the plate will be buffered, and then the two will not be damaged;

[0034] On both the left and right sides inside the second processing table 2, lifting grooves 8 and movable grooves 9 are respectively provided. There are six lifting grooves 8. The upper ends of the three left-side lifting grooves 8 and the upper ends of the three right-side lifting grooves 8 are respectively communicated with the two movable grooves 9. Two threaded rods 504, threaded rod 506 and threaded rod 507 are respectively arranged inside the six groups of lifting grooves 8. The setting of the lifting grooves 8 provides a moving space for the lifting plate 508, enabling the lifting plate 508 to move vertically smoothly. Two motors 501 are respectively arranged inside the two movable grooves 9. The setting of the movable grooves 9 provides an installation space for the motors 501 and at the same time provides a rotating space for the spur gear 502 and the spur gear 503. On the upper left and right sides of the second processing table 2, sealing plates 10 are fixedly installed by bolts. The two sealing plates 10 are respectively arranged above the two movable grooves 9. On the lower left and right sides of the second processing table 2, lifting grooves 11 are respectively provided. The lower end of the L-shaped lifting rod 703 is located inside the right-side lifting groove 11, and the lower end of the L-shaped lifting rod 709 is located inside the left-side lifting groove 11. The setting of the lifting grooves 11 provides a moving space for the L-shaped lifting rod 709, enabling the L-shaped lifting rod 709 to move vertically smoothly;

[0035] It should be noted that the two motors 501 are coordinated by the main controller to unify the rotation speed and direction of each motor, ensuring the synchronous movement of each end of the lifting block. A sensor is installed on the lifting block to monitor the displacement of each end in real time, and the motor output is adjusted through closed-loop control to eliminate the synchronous error, enabling the two motors 501 to work synchronously, and then driving the three lifting plates 508 to lift synchronously. Among them, when the tray 6 is empty, when the lifting plate 508 drives the tray 6 to move upward to the highest position, the distance between the tray 6 and the plate is reduced, avoiding the plate from falling too long and flipping and offsetting, affecting the stacking effect, or tipping over. And when the tray 6 is at the highest position, the height between the upper surface of the tray 6 and the laser cutting head 410 during cutting work is greater than the thickness of the ship plate and there is still a certain distance, so that when the laser cutting head 410 cuts the plate, the penetrating laser will not fall on the tray 6, avoiding damage to the tray 6.

[0036] The discharging mechanism 7 includes a mounting frame 701, and the mounting frame 701 is arranged above the right side of the second processing table 2. A second lifting cylinder 702 is arranged on the upper surface of the mounting frame 701. The lower end of the second lifting cylinder 702 penetrates through the mounting frame 701 and is fixedly connected to an L-shaped first lifting rod 703. The left side of the upper end of the L-shaped first lifting rod 703 is hinged to a right baffle 705 through a hinge rod 704. The right baffle 705 is located above the right end of the hollow groove of the second processing table 2. The lower ends of the front and rear sides of the right baffle 705 are both abutted against front and rear baffles 706. The two front and rear baffles 706 are respectively arranged on the front and rear sides of the hollow groove of the second processing table 2. The lower ends of the two front and rear baffles 706 are both connected to the inner part of the upper end of the second processing table 2 through springs 707. The left side of the lower end of the L-shaped first lifting rod 703 is provided with a lifting seat 708. The left side of the lifting seat 708 is provided with an L-shaped second lifting rod 709. The upper end of the L-shaped second lifting rod 709 is provided with a third lifting cylinder 710, and the third lifting cylinder 710 is arranged inside the right side of the first processing table 1. Among them, the second lifting cylinder 702 and the third lifting cylinder 710 are also coordinated in the lifting process by the main controller. The upper surface of the lifting seat 708 is provided with four groups of belt wheel transfer devices 711. The belt wheel transfer devices 711 are located below the tray 6. The belt wheel transfer devices 711 are prior art, so they will not be elaborated here. And the four belt wheel transfer devices 711 are respectively located on the front, rear, and middle sides of the three lifting plates 508, so that when the belt wheel transfer devices 711 move vertically upward, they will not contact the lifting plates 508;

[0037] Horizontal movement grooves 12 are respectively opened on the left and right sides of the front and rear ends above the second processing table 2. The left and right ends of the two front and rear baffles 706 are respectively arranged inside the four horizontal movement grooves 12. The bottom parts of the front and rear ends of the right baffle 705 are respectively arranged inside the two right-side horizontal movement grooves 12. The setting of the horizontal movement grooves 12 can limit the right baffle 705 while not affecting the left and right horizontal movement of the right baffle 705, and also provide space for the vertical movement of the front and rear baffles 706. The left side walls of the front and rear ends of the right baffle 705 and the upper right sides of the two front and rear baffles 706 are all wedge-shaped designs. The wedge-shaped design enables the right baffle 705 to smoothly push the front and rear baffles 706 to move vertically downward when moving horizontally to the left;

[0038] It should be noted that when the right baffle 705 moves to the leftmost end, it can press down the two front and rear baffles 706 while positioning the right end of the ship plate. For example, the left side wall of the right baffle 705 is at zero scale. Starting from this end, the laser cutting head 410 moves leftward (not exceeding the left side of the blanking chute at most), and the width of the plate that can be cut is equal to the moving distance. The two front and rear baffles 706 pressed down by the right baffle 705 can limit the front and rear sides of the plate, enabling the cut plate to fall smoothly without tilting or offsetting during the fall. When the tray 6 is full of plates, the right baffle 705 moves to the right, causing the front and rear baffles 706 to lose the limiting effect. The elastic force of the spring 707 is released, pushing the front and rear baffles 706 upward so that they move above the plate at the highest end. At this time, when the tray 6 moves horizontally backward, the plate will not contact the front and rear baffles 706, allowing the tray 6 to discharge smoothly.

[0039] When the present invention is in use, first, the ship plate to be cut is lifted by a lifting device onto the upper surface of the processing table 1. Then, two electric telescopic rods 308 are started, and the two electric telescopic rods 308 drive the two moving frames 309 to move towards the plate, so that the limiting guide rollers 310 inside them respectively abut against the front and rear sides of the plate. Then, the first motor 301 is started. The first motor 301 drives the second sprocket 303 and the first threaded rod 304 to rotate through the first sprocket 302 and the toothed chain, so that the first moving block 305 drives the push plate 306 to move horizontally to the right, and the push plate 306 pushes the plate to the right. When the right end of the plate is pushed to contact the right baffle 705;

[0040] The second motor 402 is started. The second motor 402 drives the second threaded rod 403 to rotate, so that the moving frame 404 drives the mounting plate 405 to move horizontally to the left. After the mounting plate 405 drives the laser cutting head 410 to move to the preset location, the second motor 402 stops working. Then, first, the first lifting cylinder 409 drives the laser cutting head 410 to move vertically to adjust the height. Then, the third motor 406 is started. The third motor 406 drives the third threaded rod 407 to rotate, so that the moving table 408 drives the laser cutting head 410 to move horizontally forward. After the laser cutting head 410 moves to the frontmost end, the first cutting operation of the plate is completed, and the plate cut on the right side will fall onto the surface of the tray 6 by gravity;

[0041] After that, the limiting transfer mechanism 3 continues to push the ship plate to the right. At the same time, the fourth motor 501 works, driving the first spur gear 502, the second spur gear 503 and the fourth threaded rod 504 to rotate. The rotation of the fourth threaded rod 504 drives the fifth threaded rod 506 and the sixth threaded rod 507 to rotate through the synchronous belt mechanism 505, so that the three lifting plates 508 move downward synchronously by the height of one plate thickness, and then drive the tray 6 to move downward by the height of one plate thickness, waiting for the next material receiving operation;

[0042] After repeating the above operations multiple times and the tray 6 is filled with sheets, the second lifting cylinder 702 and the third lifting cylinder 710 are activated. The second lifting cylinder 702 drives the first L-shaped lifting rod 703 to move upward, drives the right baffle 705 to move to the right through the hinge rod 704, so that the right baffle 705 loses the limit and fixation on the front and rear baffles 706. Under the action of the elastic force of the spring 707, the front and rear baffles 706 move above the sheets and no longer block the front and rear sides of the uppermost sheet. The third lifting cylinder 710 drives the second L-shaped lifting rod 709 to move upward, thereby driving the lifting seat 708 and the belt wheel transfer device 711 to move upward, so that the synchronous belt of the belt wheel transfer device 711 contacts the bottom of the tray 6, and at the same time can drive the tray 6 to move upward a small distance, so that the tray 6 no longer contacts the lifting plate 508. Then the belt wheel transfer device 711 works to transfer the tray 6 filled with sheets out of the second processing table 2 backward, and the empty tray 6 at the front end is moved into the second processing table 2 to wait for the continuation of the cutting and stacking work.
