[0002] Laser cutting machine is a high-precision and high-efficiency processing equipment. It uses a high-power density laser beam to irradiate the surface of the workpiece, so that the workpiece reaches the melting point or boiling point and then melts or vaporizes, and the molten or vaporized material is blown away by high-pressure gas coaxial with the beam, thereby realizing the cutting of the material. This equipment has the advantages of high precision, fast cutting speed, smooth incision, and low processing cost. It can process a variety of materials including metal, plastic, wood, textiles, ceramics, etc. Laser cutting machines are widely used in many industries and fields such as automobiles, machinery, electronics, medical treatment, clothing, and handicraft processing.

In addition, the laser cutting machine adopts computerized digital control technology to realize automated operation and improve production efficiency and consistency.

[0003] In the prior art, the shell that protects the optical components of the laser cutting machine usually adopts a single heat dissipation method, such as natural heat dissipation or simple air cooling. However, this single heat dissipation method is often incapable of dealing with the heat generated by the high-power laser cutting machine during long-term operation. The temperature inside the shell is easily too high, resulting in performance degradation or even damage to the optical components, thereby shortening the service life of the optical components. In addition, temperature instability will also affect the accuracy and stability of laser cutting, reducing the overall performance of the laser cutting machine, and improvement is needed. To this end, a laser cutting machine with dual cooling of water cooling and air cooling is proposed. Utility Model Content

[0025] When in use, cooling water is provided in the water tank 3, the water storage box 4 and the water storage ring 5. The water tank 3 and the water storage box 4 are in contact with the outer wall of the shell 1. The cooling water therein absorbs the heat in the shell 1 by heat exchange, thereby achieving the effect of water cooling inside the shell 1.

[0026] The water tank 3, the water storage box 4, the transverse pipe 6, the water storage ring 5 and the return pipe 12 are interconnected to form a cooling water circulation pipeline. The water pump 7 is started, and the water pump 7 pumps the cooling water in the water tank 3 into the water storage ring 5 through the transverse pipe 6. The cooling water circulates in the water storage ring 5. At the same time, the motor 8 drives the fan blades 10 to rotate to form wind flow. The wind flow enters the interior of the shell 1 through the air inlet hole 11, mixes with the high-temperature hot air in the shell 1, and takes away the heat, thereby realizing air cooling inside the shell 1;

[0027] The laser cutting machine is equipped with a dual cooling system of water cooling and air cooling, which can efficiently cool the housing 1 that protects the optical components, ensuring that the laser cutting head 2 maintains an ideal temperature range during continuous operation, thereby extending the service life of the optical components and improving the accuracy and stability of laser cutting.

[0032] The top of the housing 1 is provided with evenly distributed air outlet holes 15;

[0033] The top of the shell 1 is provided with evenly distributed air outlet holes 15.

[0034] The motor 8 and the fan blades 10 are both arranged inside the water storage ring 5;

[0035] The motor 8 and the fan blades 10 are both arranged inside the water storage ring 5. The motor 8 drives the fan blades 10 to rotate inside the water storage ring 5 to form wind flow. Since the water storage ring 5 is filled with cooling water, the wind flow will exchange heat with the cooling water when passing through the water storage ring 5, and then be blown into the shell 1 after the temperature is reduced, thereby achieving a more effective cooling effect. At the same time, it can also cool the motor 8 and the fan blades 10, reduce the power consumption of the motor 8 during long-term operation, and increase its service life.

The aluminum alloy has high strength and thermal conductivity, and can quickly transfer the heat in the shell 1 to the outside to improve the heat dissipation efficiency. The surface of the shell 1 is provided with anti-corrosion paint, which can prevent the shell 1 from rusting due to long-term use, thereby ensuring the stability and safety of the laser cutting machine.

[0038] The housing 1 is provided with a controller, which is electrically connected to the laser cutting head 2, the water pump 1 7, the motor 8, the temperature sensor, the water pump 2 13 and the cooling pipe 14 respectively;

[0039] As the central control unit of the entire laser cutting machine, the controller controls the laser cutting head 2, water pump 1 7, motor 8, water pump 2 13 and cooling pipe 14 according to the temperature data monitored by the temperature sensor and the user's needs to ensure that the laser cutting machine always maintains the best working condition.

The water tank 3 and the water storage box 4 are in contact with the outer wall of the shell 1. The cooling water therein absorbs the heat in the shell 1 by heat exchange, thereby achieving the effect of water cooling inside the shell 1.

[0042] The water tank 3, the water storage box 4, the transverse pipe 6, the water storage ring 5 and the return pipe 12 are interconnected to form a cooling water circulation pipeline. The water pump 7 is started, and the water pump 7 pumps the cooling water in the water tank 3 into the water storage ring 5 through the transverse pipe 6. The cooling water circulates in the water storage ring 5. At the same time, the motor 8 drives the fan blades 10 to rotate to form wind flow. The wind flow enters the interior of the shell 1 through the air inlet 11, mixes with the high-temperature hot air in the shell 1, and is then discharged through the air outlet 15 to take away the heat, thereby realizing air cooling inside the shell 1;

[0045] The motor 8 and the fan blades 10 are both arranged inside the water storage ring 5. The motor 8 drives the fan blades 10 to rotate inside the water storage ring 5 to form a wind flow. Since the water storage ring 5 is filled with cooling water, the wind flow will exchange heat with the cooling water when passing through the water storage ring 5, and then blow into the housing 1 after the temperature is reduced, thereby achieving a more effective cooling effect. At the same time, the motor 8 and the fan blades 10 can also be cooled, thereby reducing the power consumption of the motor 8 when it runs for a long time and increasing its service life.

[0046] The shell 1 is made of high-strength aluminum alloy. The aluminum alloy has high strength and thermal conductivity, and can quickly transfer the heat in the shell 1 to the outside to improve the heat dissipation efficiency. The surface of the shell 1 is provided with anti-corrosion paint, which can prevent the shell 1 from rusting due to long-term use, thereby ensuring the stability and safety of the laser cutting machine.
