Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, in particular to a metal plate laser cutting machine. Background Art

[0002] Laser cutting uses a focused high-power laser beam to irradiate the surface of the material, causing it to reach a local melting, vaporization or combustion temperature instantly. At the same time, auxiliary gases (such as oxygen and nitrogen) are used to blow away the slag to form a clean and precise cut.

[0003] However, in the existing technology for cutting metal plates, the metal plates are placed on sword bars and then cut by laser. The waste and slag generated by the cutting stick to the sword bars and under the sword bars, making them difficult to clean. Moreover, when the gaps between the sword bars are large during thin plate processing, the gaps between the sword bars can easily cause the thin plate to sag, affecting the cutting accuracy.

[0066] Working principle:

[0067] First, place both sides of the metal plate 49 between the two clamping plates 46 on both sides respectively, control the motor 1 44 to drive the screw 45 to rotate, so that the upper clamping plate 46 approaches the metal plate 49 and clamps the two sides of the metal plate 49, and then start the motor 2 62 to drive the gear 1 63 to rotate forward, so that the forward rotation of the gear 1 63 satisfies the direction of the rotation of the one-way gear 1 48 to drive the double-section reciprocating threaded rod 1 41, and the double-section reciprocating threaded rod 1 41 rotates to make the two movable plates 1 42 move away from each other, and when moving away, it drives the upper metal plate clamping and tensioning mechanism 4 to move to tension the clamped metal plate 49. A tension sensor is installed at the connection position between the guide rod 2 47 and the mounting frame 33. When the tension detected by the tension sensor reaches the specified upper limit, the motor 2 62 is turned off to perform the cutting step;

[0068] Start the motor 2 62 to drive the gear 1 63 in the reverse direction, so that the gear 1 63 satisfies the direction of the one-way gear 2 52 to drive the reciprocating screw 1 51 to rotate, so that the movable plate 2 53 moves back and forth on the reciprocating screw 1 51, and when moving, it drives the upper frame 59 and other structures to move to the next cutting position, and then start the motor 3 527 to drive the gear 2 528 to rotate forward. The forward rotation of the gear 2 528 satisfies the direction of the one-way gear 3 57 to drive the double-section reciprocating threaded rod 2 56 to rotate, so that the two movable plates 3 58 drive the two frames 59 and other structures to move toward the metal plate 49, so that the frame 59, the pressure plate 1 510, the crawler 1 513, the sword bar 514, the pressure plate 2 515, and the crawler 2 518 are in contact with the top and bottom of the metal plate 49, and the metal plate 49 needs to be cut next. The position to be processed is supported and pressure is applied, and the metal plate 49 is supported to prevent the metal plate 49 from sagging due to its own gravity, so that the cutting position is in a horizontal state. At the same time, pressure is applied to the metal plate 49 at this position to make it in a flat state. The reason for adjusting the metal plate 49 is that a longer thin metal plate 49 will have creases when it is stored or processed. In addition, the thin metal plate 49 will have slight deformation at the cutting position during laser cutting. If laser cutting is performed on this area again, the deformation generated previously needs to be flattened to avoid cutting errors. Therefore, when necessary, it is necessary to start the heating roller 1 512 and the heating roller 2 517 to heat the metal plate 49, and apply slight 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, and the reverse rotation of the gear two 528 satisfies the direction of the rotation of the one-way gear four 523 to drive the reciprocating screw two 522, so that the movable plate four 524 drives the rack 526 to move down and mesh with the two gear threes 520 respectively. When the rack 526 moves down and meshes, the gear three 520 meshes and drives the bidirectional screw two 519 to rotate, so that the multiple movable frames 521 respectively drive the pressing plate one 510 and the pressing plate two 515 to move, and the pressing plate one 510 drives the heating roller one 512 and the crawler one 513 to move. When moving, the crawler one 513 drives the heating roller one 512 to roll, and the pressing plate two 515 drives the heating roller two 517 and the crawler two 518 to roll. When the crawler rolls, the friction of the pressing plate on the metal plate 49 can be reduced to avoid pulling the processing area of ​​the metal plate 49 while ensuring the flatness after the processing area is opened. After the processing area is opened, the sword bar 514 below supports the bottom of the metal plate 49;

[0070] Then start the rodless cylinder 1 21 and the rodless cylinder 2 22 to drive the cylinder 24 and the laser cutter 25 to move to the processing area, and then start the cylinder 24 to make the laser cutter 25 close to the metal plate 49, and then start the laser cutter 25 to laser open the metal plate 49. The laser cutting slag and the cut workpiece fall on the table 12 for easy cleaning. After the cutting is completed, start the motor 3 527 to drive the gear 2 528 to reverse, so that the rack 526 moves up to mesh with the gear 3 520, and drives the bidirectional screw 2 519 to rotate. The multiple moving frames 521 are used to respectively drive the structures such as the pressing plate 1 510 and the pressing plate 2 515 to move and reset, and the processing part is re-covered. When the pressing plate 2 515 is reset, the cutting slag on the sword bar 514 is cleaned. After covering, the processing part can be heated to repair the deformed cutting position. Then, the motor 3 527 is started to drive the gear 2 528 to rotate forward, so that the double-section reciprocating threaded rod 2 56 drives the two frames 59 to move away, releasing the support for the metal plate 49, and then the motor 2 62 is started to process the next position.

[0071] When a slope needs to be cut during the processing process, the four hydraulic cylinders 31 can be adjusted. The hydraulic cylinders 31 push the universal joint 32 and other structures to move, so that the metal plate 49 tilts in different directions. At the same time, the laser cutting mechanism 2 drives the laser cutting machine 25 to move, so that a slope is formed on the edge of the hole during the hole opening operation, and no subsequent slope processing is required.

[0072] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
