Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a laser cutting machine for metal plates. Background Art

[0002] Laser cutting irradiates the surface of the material with a high-power laser beam after focusing, so that the local area reaches the melting, vaporization or combustion temperature instantaneously. At the same time, with the help of auxiliary gases (such as oxygen, nitrogen), the molten slag is blown away to form a clean and precise cutting seam.

[0003] However, in the existing technology for cutting metal plates, the metal plate is placed on the sword grid bars, and then cut by laser. The waste materials and molten slag generated during cutting adhere to the sword grid bars and below the sword grid bars, which is difficult to clean. Moreover, when the gaps between the sword grid bars are large during the processing of thin plates, the gaps between the sword grid bars are likely to cause the sagging of the thin plates, affecting the cutting accuracy.

[0066] Working principle:

[0067] First, place both sides of the metal plate 49 between two clamping plates 46 on both sides. Control the first motor 44 to drive the screw 45 to rotate, so that the upper clamping plate 46 approaches the metal plate 49 to clamp both sides of the metal plate 49. Then start the second motor 62 to drive the first gear 63 to rotate forward, so that the forward rotation of the first gear 63 meets the rotation direction of the single-direction gear 48 to drive the double-section reciprocating threaded rod 41 to rotate. The rotation of the double-section reciprocating threaded rod 41 makes the two first moving plates 42 move away from each other. When moving away, it drives the metal plate clamping and tensioning mechanism 4 above to move to tension the clamped metal plate 49. A tension sensor is installed at the connection position of the second guide rod 47 and the mounting bracket 33. After the tension detected by the tension sensor reaches the specified upper limit, turn off the second motor 62 to perform the cutting step;

[0068] Start the second motor 62 to drive the first gear 63 to rotate in reverse, so that the first gear 63 meets the rotation direction of the single-direction gear 52 to drive the reciprocating screw rod 51 to rotate, so that the second moving plate 53 reciprocates on the reciprocating screw rod 51. When moving, it drives the upper frame 59 and other structures to move to the next cutting position. Then start the third motor 527 to drive the second gear 528 to rotate forward. The forward rotation of the second gear 528 meets the rotation direction of the single-direction gear 57 to drive the double-section reciprocating threaded rod 56 to rotate, so that the two third moving plates 58 drive the two frames 59 and other structures to move towards the metal plate 49, so that the frame 59, the first pressing plate 510, the first track 513, the sword grid bars 514, the second pressing plate 515, and the second track 518 contact the top and bottom of the metal plate 49 to support and apply pressure to the position of the metal plate 49 that needs to be processed next, support the metal plate 49 to prevent the metal plate 49 from sagging due to its own gravity, so that the cutting part is in a horizontal state, and apply pressure to the metal plate 49 at this part to make it flat while supporting. The reason for adjusting the metal plate 49 is that long thin metal plates 49 will produce creases during storage or processing. In addition, slight deformation will occur at the cutting position when the thin metal plate 49 is laser cut. If laser cutting is performed on this area again, the previous deformation needs to be leveled to avoid cutting errors. Therefore, when necessary, start the first heating roller 512 and the second heating roller 517 to heat the metal plate 49, and slightly apply pressure and heat to repair the deformed position of the metal plate 49;

[0069] The starting motor three 527 drives the gear two 528 to reverse. The reverse rotation of the gear two 528 meets the steering requirement for the unidirectional gear four 523 to drive the reciprocating screw two 522 to rotate, causing the moving plate four 524 to drive the rack 526 to move downward and engage with the two gears three 520 respectively. When the rack 526 moves downward and engages, the gear three 520 engages and drives the bidirectional screw two 519 to rotate, causing multiple moving brackets 521 to drive the pressing plate one 510 and the pressing plate two 515 to move respectively. The pressing plate one 510 drives the heating roller one 512 and the track one 513 to move. When moving, the track one 513 drives the heating roller one 512 to roll. The pressing plate two 515 drives the heating roller two 517 and the track two 518 to roll. When the track rolls, it can reduce the friction force of the pressing plate on the metal plate 49, avoid pulling the processing area of the metal plate 49, and ensure the flatness after opening the processing area. After the processing area is opened, the sword-shaped grid bars 514 below support the bottom of the metal plate 49;

[0070] Then start the rodless cylinder one 21 and the rodless cylinder two 22 to drive the cylinder 24 and the laser cutting machine 25 to move to the processing area. Then start the cylinder 24 to make the laser cutting machine 25 approach the metal plate 49. Then start the laser cutting machine 25 to perform laser hole opening on the metal plate 49. The laser cutting slag and the cut workpieces fall on the table 12 for easy cleaning. After cutting is completed, start the starting motor three 527 to drive the gear two 528 to reverse, causing the rack 526 to move upward and engage with the gear three 520, and drive the bidirectional screw two 519 to rotate, causing multiple moving brackets 521 to drive structures such as the pressing plate one 510 and the pressing plate two 515 to move back to their original positions and cover the processing part again. When the pressing plate two 515 returns to its original position, it cleans the cutting slag on the sword-shaped grid bars 514. After covering, heating of the processing part can be selected to repair the deformed cutting position. Then start the starting motor three 527 to drive the gear two 528 to rotate forward, causing the double-section reciprocating threaded rod two 56 to drive the two frames 59 away, releasing the support for the metal plate 49. Then start the motor two 62 to process the next position;

[0071] During the processing, when a sloped cut is required, the four hydraulic cylinders 31 can be adjusted. The hydraulic cylinders 31 push structures such as the universal joints 32 to move, causing the metal plate 49 to tilt in different directions. At the same time, in cooperation with the laser cutting mechanism 2 driving the laser cutting machine 25 to move, a slope is opened at the edge of the hole during the hole opening operation, eliminating the need for subsequent slope processing.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
