Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a plate-shaped magnetic material laser cutting machine. Background Art

[0002] Laser cutting machines mainly rely on a high-power density laser beam, which is focused and irradiated onto the surface of the workpiece, causing the material to melt, vaporize, ablate or reach the ignition point rapidly. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby cutting the workpiece.

[0003] Magnetic materials are mostly cut by laser cutting or direct cutting with a cutting knife. During the direct cutting process with a cutting knife, the magnetic material can be cooled by spraying coolant, but laser cutting cannot use coolant and has a poor cooling effect on magnetic materials. When processing plate materials, the higher temperature may cause the plate materials to bend and deform. After the material cools, the deformation is difficult to recover by itself, resulting in poor precision of the finished product or even waste. Utility Model Content

[0004] The purpose of the utility model is to solve the following problems existing in the prior art:

[0007] The utility model provides a plate-shaped magnetic material laser cutting machine.

[0008] Furthermore, the cutting device is composed of a host connected to the mobile device and a laser transmitter arranged on one side of the host.

[0009] Furthermore, the pressing block is composed of a triangular block structure and an inclined plate structure, wherein one end of the plate structure is connected to the block structure, and there are two triangular block structures in total, with a gap between the two and connected to each other.

[0010] Furthermore, the top of the block structure and the plate structure of the pressing block are respectively located on both sides of the mobile device and connected to the main body part of the cutting device.

[0011] Furthermore, the heat dissipation grille on the surface of the pressing block is provided on a side of the triangular block structure close to the cutting device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The utility model cuts the plate-like material through a cutting device, and during the cutting process, the pressing block is fitted with the plate-like material. Since the pressing block is made of an aluminum alloy material as a whole and has high thermal conductivity, the pressing block absorbs the temperature generated by the plate-like material and transmits it to the atmosphere through the heat dissipation grille, ensuring that the temperature of the plate-like material will not rise and cause deformation of itself, and the pressing block will move with the cutting device while in contact with the plate-like material. In this process, the pressing block is closely fitted with the plate-like material, which will cause excessive friction between the pressing block and the plate-like material and generate a vacuum area that cannot move smoothly. An installation groove is provided at the bottom of the pressing block, and a universal ball arranged at the bottom of the installation column on the inner wall of the installation groove abuts against the plate-like material, which does not affect the movement of the pressing block. At the same time, the universal ball is deformed and exerts a reaction force to push the pressing block through the installation rod, so that a gap is left between part of the pressing block and the plate-like material, and no vacuum area is generated.

The heat dissipation grille 5 on the surface of the pressing block 4 is opened on the side of the triangular block structure close to the cutting device 3. A mounting groove 6 is opened at the bottom of the pressing block 4, and a mounting column 7 is arranged on the inner wall of the mounting groove 6.

[0026] Description of the working principle: First, the cutting device 3 moves in the processing platform 1 through the mobile device 2, and processes the plate-like material during the movement. During the processing, the bottom of the pressing block 4 is always in contact with the plate-like material. During the contact process, the heat generated by the plate-like material during processing is absorbed and dissipated outward through the heat dissipation grille 5 on its top to ensure that the plate-like material will not be deformed due to long-term high temperature during the cutting process; at the same time, the universal ball 8 arranged at the bottom of the mounting column 7 on the inner wall of the mounting groove 6 abuts against the plate-like material, and does not affect the movement of the pressing block 4. At the same time, the universal ball 8 is deformed and exerts a reaction force to push the pressing block 4 through the mounting column 7, so that a gap is left between part of the pressing block 4 and the plate-like material to avoid the pressing block 4 and the plate material fitting too closely to produce a vacuum area that affects the normal movement of the pressing block 4.
