[0002] In existing laser cutting machine technology, the smoke exhaust structure is often designed to be placed at the bottom of the frame, that is, below the workpiece being cut. Although this design can achieve smoke exhaust to a certain extent, it has significant defects. Since the smoke is generated by the surface of the workpiece during the laser cutting process and diffuses upward, and the existing smoke exhaust structure is located below the workpiece, the smoke will be blocked by the workpiece itself during the rising process, resulting in poor smoke flow and low smoke exhaust efficiency. This not only affects the working environment of laser cutting and deteriorates the air quality in the operating area, but may also have an adverse effect on the accuracy and effect of laser cutting due to smoke accumulation. In addition, since the smoke cannot be discharged in time, it may also cause pollution to the internal components of the laser cutting machine and shorten the service life of the equipment.
[0003] Therefore, it is very necessary to invent a high-power fiber laser cutting machine. Utility Model Content

[0021] As attached Figure 1 To the attached Figure 4 As shown:
[0022] The utility model provides a high-power fiber laser cutting machine, including a cutting frame 1, a reinforcement beam 2, a positioning platform linear actuator 3, a positioning platform 4, a smoke exhaust system 5, a smoking pipe 6, a support seat 7, a transverse actuator 8, a vertical actuator 9, a pipeline drag chain 10 and a cutting laser head 11. The two parallel cutting frames 1 are fixedly installed together through the reinforcement beam 2. Each of the cutting frames 1 is connected to the positioning platform 4 through the positioning platform linear actuator 3. The positioning platform 4 is installed with the smoke exhaust system 5, and the smoke exhaust system 5 is installed with two parallel smoking pipes 6; the support seat 7 is fixedly installed on the outside of each cutting frame 1, the transverse actuator 8 is fixedly installed on the two support seats 7, the transverse actuator 8 is installed with the vertical actuator 9, and the cutting laser head 11 installed on the vertical actuator 9 is connected to the pipeline arranged inside the pipeline drag chain 10, and the two ends of the pipeline drag chain 10 are respectively connected to the transverse actuator 8 and the vertical actuator 9.
[0023] Furthermore, the smoke exhaust system 5 includes a smoking linear actuator 51, a smoking box 52, a smoking pipe outlet 53 and a smoking fan 54. There are two smoking linear actuators 51, and the two smoking linear actuators 51 are installed in parallel on the positioning platform 4. Each smoking linear actuator 51 is installed with a smoking box 52, and the smoking box 52 is provided with several smoking pipe outlets 53, and each smoking pipe outlet 53 is fixedly installed with a smoking fan 54.
[0024] Furthermore, each smoking box 52 is provided with a plurality of smoking nozzles 53, each of which is fixedly mounted with a smoking fan 54. Notably, the smoking fans 54 are strategically positioned within the smoking box 52, matching the number of smoking nozzles 53 to form a corresponding arrangement. This design ensures that both smoking nozzles 53 in each smoking box 52 are in smooth communication with the smoking duct 6, effectively directing smoke into the smoking duct.
[0025] Furthermore, to further optimize smoke emission, smoke exhaust nozzles 55 are installed on the smoking chamber 52. These nozzles are tightly connected to smoke exhaust ducts 56 via flanges. The smoke exhaust ducts 56 are cleverly installed within a smoke exhaust chain 57. This design not only enhances system stability but also ensures smooth and unobstructed smoke transmission. The ends of the smoke exhaust chain 57 are fixed to the smoking chamber 52 and the positioning platform 4, respectively, forming a complete smoke exhaust channel.
[0026] Furthermore, one end of the smoke exhaust duct 56 is connected to a smoking box 58 fixedly installed on one side below the positioning platform 4. The smoking box 58 is equipped with a smoking assembly fan component, whose main function is to further draw the smoke inside the smoking box 52 into the smoking box 58, thereby realizing centralized treatment and discharge of the smoke.
[0027] Furthermore, there is sufficient space between the two smoke pipes 6 to ensure that the laser emitted by the cutting laser head 11 can act on the workpiece without obstruction. At the same time, the two smoke pipes 6 do not interfere with each other in function and work together to achieve effective collection of smoke.
[0028] Furthermore, to further improve smoke collection efficiency, a number of smoke holes are evenly distributed linearly along the smoke duct 6. These holes ensure that smoke, once generated, is quickly drawn into the smoke duct 6 and subsequently into the smoke box 52 for processing. This design not only improves smoke collection efficiency but also optimizes the performance of the entire smoke exhaust system.
[0029] The working principle is as follows: First, the workpiece is fixed on the positioning platform 4 using a positioning fixture. This is a prerequisite for the high-power fiber laser cutting machine to perform cutting operations. The positioning platform 4 is connected to the cutting frame 1 via the positioning platform linear actuator 3, which enables precise workpiece positioning and provides a stable reference for subsequent laser cutting.
[0030] Then, the cutting laser head 11, working in conjunction with the horizontal actuator 8 and the vertical actuator 9, cuts the workpiece along a predetermined trajectory. These two actuators are responsible for the horizontal and vertical movement of the laser head, respectively. Through a precise control system, the laser head can achieve three-dimensional cutting of the workpiece.
[0031] During the laser cutting process, a large amount of smoke and harmful gases are generated. If these fumes are not removed in time, they will not only affect the cutting quality but also pose a threat to the health of the operator. Therefore, the high-power fiber laser cutting machine of the present invention is specially designed with a smoke exhaust system 5 to effectively collect and remove the smoke generated during the cutting process.
[0032] The smoke exhaust system 5 consists of key components, including a smoke linear actuator 51, a smoke box 52, a smoke outlet 53, and a smoke blower 54. Two parallel smoke linear actuators 51 are mounted on the positioning platform 4, each with a smoke box 52 attached. The smoke box 52 is equipped with multiple smoke outlets 53, each of which houses a smoke blower 54. This design ensures that smoke, once generated, is quickly drawn into the smoke box 52 and transported through the smoke duct 6 to subsequent smoke treatment equipment.
[0033] To further optimize smoke exhaust, smoke exhaust nozzles 55 are installed on the smoking box 52. These nozzles are tightly connected to smoke exhaust ducts 56 via flanges. These ducts are cleverly installed within the smoke exhaust drag chain 57, enhancing system stability and ensuring smooth, unimpeded smoke transmission. Ultimately, the smoke is transported through the exhaust ducts 56 to the smoking box 58 below the positioning platform 4, where it is centrally processed and discharged by the smoke exhaust assembly fan.
[0034] Furthermore, ample space is left between the two smoke ducts 6 to ensure that the laser light emitted by the cutting laser head 11 can reach the workpiece unimpeded. Furthermore, several smoke holes are evenly distributed linearly along the smoke duct 6 to further improve smoke collection efficiency. This design not only optimizes the performance of the entire smoke exhaust system but also ensures the safety and efficiency of laser cutting operations.
[0035] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
