Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a laser cutting device for cutting a composite plate. Background Art

[0002] The side body decorative panel assembly skin is an important part of the bus body structure. It not only has a decorative effect, but also bears the functions of protecting the body structure, improving the body rigidity and reducing driving noise. When processing and producing the side body decorative panel assembly skin, in order to ensure the cutting accuracy, laser cutting equipment is usually used to cut the composite plate.

[0003] When the laser cutting equipment is in use, after the composite sheet is placed, the equipment is started for laser cutting. Since laser cutting generates a lot of heat, in order to reduce the impact of laser cutting on the composite sheet and prevent thermal deformation of the composite sheet, the composite sheet is usually cooled during the laser cutting process. However, in existing laser cutting equipment, water cooling or air cooling is generally used to cool the composite sheet. When water cooling is used, only a follow-up nozzle is set near the laser, and the water sprayed by the nozzle acts on one side of the laser at the first time. For other areas near the laser, the cooling effect is average. When air cooling is used for cooling, the wind blown out will cause the dispersion of smoke and dust, which will cause environmental pollution, and the effect of use is average.

At the same time, the moving seat 3 moves with the follower rod 4 on the equipment body 1, and the laser 5 can move on the follower rod 4 to achieve special-shaped cutting. During the cutting process, the wind blown by the blowing structure 6 can act on the surface of the composite sheet to blow away the dust and ensure the cutting effect. At the same time, the water sprayed by the water cooling structure 7 acts on the composite sheet to cool the composite sheet to prevent the composite sheet from being deformed due to heat. The sprayed water can also moisten the smoke and carry the particulate matter in the smoke into the collection bucket 8, and finally be discharged from the drain pipe 9.

[0022] Through the above implementation scheme, the blowing structure 6 includes a connecting pipe 601, an annular air outlet pipe 602, a connecting pipe 603, a fixing seat 604, a block 605, a support column 606, a movable rod 607, an anti-sliding block 608, a clamping plate 609, a connecting block 610 and a spring 611. The connecting pipe 601 is fixedly connected to the annular air outlet pipe 602, and two connecting pipes 603 are symmetrically installed on the connecting pipe 601, one end of the connecting pipe 603 is closed, and the other connecting pipe 603 is completely penetrated, the block 605 is arranged on the connecting pipe 603, the fixing seat 604 is fixed to the connecting pipe 601 through the support column 606, and the movable rod 607 is fixedly connected with the anti-sliding block 608, and the movable rod 607 passes through the fixed seat 604, the clamping plate 609 is connected to the end of the movable rod 607 through the connecting block 610, the spring 611 is sleeved on the movable rod 607, and the ends of the spring 611 contact the fixed seat 604 and the clamping plate 609 respectively, the water cooling structure 7 includes a shunt pipe 701, a nozzle 702, a water inlet joint 703, a mounting rod 704, a magnet 705, a metal connecting frame 706 and a socket 707, the nozzle 702 is distributed in an annular array on the shunt pipe 701, and the shunt pipe 701 is fixedly connected with the water inlet joint 703, and the magnet 705 is fixed on the mounting rod 704, and the mounting rod 704 is symmetrically mounted on the shunt pipe 701, the jack 707 is opened at the lower end of the metal connecting frame 706, and the metal connecting frame 706 is sleeved on the connecting pipe 603, and a blowing structure 6 is arranged on the laser 5, and the annular air outlet pipe 602 is used for blowing. The blown wind curtain surrounds the laser 5, and dust can be cleaned in any direction to avoid dust and other impurities on the composite plate from affecting the laser cutting effect. The blowing structure 6 is provided with a fixed seat 604, a movable rod 607, a tightening plate 609, a spring 611 and other structures, and the blowing structure 6 is installed in an elastic tightening manner, and the installation method is convenient. It is convenient and easy to disassemble. The water-cooling structure 7 is set up to cool the composite plate by water cooling, which can effectively prevent the composite plate from thermal deformation. The ring array of nozzles 702 is set on the shunt pipe 701, which can evenly cool the area around the laser 5 to ensure the cooling effect. The mounting rod 704 is installed on the connecting pipe 603 by the metal connecting frame 706, which is convenient for installation and disassembly. After installation, the stability can be ensured by the adsorption of the magnet 705 and the metal connecting frame 706. The water-cooling structure 7 and the blowing structure 6 can also play a certain shielding role, which can avoid the dispersion of dust generated by cutting.

[0023] When installing the blowing structure 6 and the water-cooling structure 7, first install the blowing structure 6, pull the movable rod 607 through the anti-sliding block 608, and the movable rod 607 moves to make way with the holding plate 609 through the connecting block 610, and the spring 611 is compressed, and then the connecting pipe 601 and the annular air outlet pipe 602 are set around the laser 5.

Under the action of the magnet 705, the metal connecting frame 706 is relatively fixed to the mounting rod 704, thereby completing the installation of the water cooling structure 7. The water source pipe is connected to the water inlet joint 703 for use. During the laser cutting process, the compressed gas in the gas source enters the connecting pipe 601 through the through connecting pipe 603, and is finally blown out from the annular air outlet pipe 602 to form an annular air curtain. The air curtain acts on the composite plate, which can effectively clean the dust and ensure the cutting effect. The water at the water source enters the diverter pipe 701 through the water inlet joint 703, and is finally sprayed onto the composite plate from the nozzle 702, which can effectively cool the area on the composite plate being cut. At the same time, the sprayed water can also carry the smoke and dust particles into the collecting bucket 8, thereby achieving the effect of dust reduction.
