Description

Technical Field

[0001] This utility model belongs to the field of laser cutting and welding technology, specifically a fiber laser cutting and welding integrated machine. Background Technology

[0002] The fiber laser cutting and welding integrated machine is a high-tech equipment that integrates laser cutting and welding functions. It combines the advantages of fiber lasers with the characteristics of CNC technology and precision mechanical technology, and is widely used in many industries.

[0003] The working principle of a fiber laser cutting and welding integrated machine is based on the laser beam emitted by a fiber laser. After being focused, these laser beams can form a high-energy-density spot on the surface of the workpiece, causing the irradiated area to melt and vaporize instantly, thereby achieving the cutting or welding of the workpiece. When the workpiece is irradiated by the laser beam, it will produce fumes. These fumes contain a large number of tiny particles. However, existing fiber laser cutting and welding integrated machines are not convenient for treating these fumes generated during processing. The tiny particles in the fumes will drift into the air and pollute the working environment.

[0004] Therefore, this utility model provides an integrated fiber laser cutting and welding machine. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 5As shown in the figure, the fiber laser cutting and welding integrated machine of this utility model includes a body 1; a fiber laser 12 is installed on the top of the body 1; a cutting groove 13 is opened in the middle of the body 1; a waste discharge groove 14 is opened inside the body 1; an air extractor 15 is fixedly connected to the side wall of the body 1; the air inlet of the air extractor 15 is connected to the waste discharge groove 14; a plurality of guide holes 16 are opened on the side wall of the cutting groove 13; the plurality of guide holes 16 connect the waste discharge groove 14 and the air extractor 15; an air extraction range limiting component is installed inside the cutting groove 13; a filter component is installed in the middle of the waste discharge groove 14; during operation, When laser cutting or welding a workpiece using a fiber laser 12, the workpiece will melt, evaporate, or burn due to heat, generating a certain amount of fumes. At this time, the exhaust fan 15 is activated to extract the fumes. Some of the fumes generated during workpiece processing will enter the interior of the waste discharge tank 14 through the cutting groove 13 and guide hole 16 with the airflow, and be treated by the filter assembly. Then, the treated gas enters the exhaust fan 15 and is discharged. Through the above structure, the fumes generated during laser cutting and welding can be treated, reducing the occurrence of harmful substances in the fumes escaping into the air and causing pollution to the working environment, thereby reducing the impact on the health of workers.

[0025] like Figures 1 to 4 As shown, the air extraction range limiting component includes a lead screw 2; the lead screw 2 is rotatably connected to the middle of the cutting groove 13; both sides of the cutting groove 13 are provided with sliding grooves 21; a sliding frame 22 is slidably connected to the middle of a pair of sliding grooves 21; the sliding frame 22 is threadedly connected to the middle of the lead screw 2; elastic membranes 23 are fixed to both sides of the sliding frame 22; the other end of the elastic membrane 23 is fixed to the side wall of the cutting groove 13; during operation, when laser cutting or welding a workpiece, the motor drives the lead screw 2 to rotate, thereby driving the sliding frame 22 to move with the fiber laser 12, thus limiting the air extraction range. When the workpiece is being processed, the sliding frame 22 can move with the laser irradiation position. During the evacuation, a negative pressure is formed inside the cutting groove 13, causing the two ends of a pair of elastic membranes 23 to adhere to the bottom of the sliding groove 21. At this time, most of the gas flowing above will enter the cutting groove 13 through the sliding frame 22, thereby making the suction force of the evacuation more concentrated. With the above structure, the evacuation force near the processing point can be increased when extracting the fumes generated during processing, thereby improving the extraction effect of the fumes generated during processing and further reducing the occurrence of fumes escaping into the air and affecting the working environment.

[0026] like Figures 1 to 5As shown, the filter assembly includes a mounting groove 3; a mounting frame 31 is slidably connected to the middle of the mounting groove 3; an activated carbon filter plate 32 is detachably mounted on the middle of the mounting frame 31; a limiting rod 33 is rotatably connected to the side wall of the body 1; during operation, when it is necessary to clean or replace the activated carbon filter plate 32, the mounting frame 31 is slid out from the inside of the body 1, and then the activated carbon filter plate 32 is cleaned or replaced. After completion, the mounting frame 31 is slid back into the inside of the body 1 along the mounting groove 3, and the limiting rod 33 is rotated so that the bottom end of the limiting rod 33 naturally hangs down and blocks the side wall of the mounting frame 31, so that the mounting frame 31 will not easily slide. Through the above structure, the activated carbon filter plate 32 can be easily replaced or cleaned, improving the ease of use of the device.

[0027] like Figures 1 to 5 As shown, a rubber pad 4 is fixed to the side wall of the mounting frame 31; a spring 41 is fixed to the side wall of the mounting groove 3. During operation, when the activated carbon filter plate 32 needs to be replaced, the limiting rod 33 is rotated so that the limiting rod 33 no longer restricts the mounting frame 31. At this time, the mounting frame 31 will pop out from inside the body 1 under the elastic force of the spring 41. After cleaning is completed and the mounting frame 31 is slid into the body 1, the rubber pad 4 will fit tightly against the side wall of the body 1, reducing the gap between the body 1 and the mounting frame 31. Through the above structure, the convenience of cleaning the activated carbon filter plate 32 can be improved, and the situation where air leakage between the body 1 and the mounting frame 31 causes a decrease in suction power when extracting flue gas can be reduced.

[0028] like Figures 1 to 2 As shown, a liquid tank 5 is provided at the bottom of the waste discharge tank 14; a liquid inlet pipe 51 is fixedly connected to the side wall of the machine body 1; a liquid outlet pipe 52 is fixedly connected to the side wall of the machine body 1; and an observation window 53 is fixedly connected to the side wall of the machine body 1. During operation, some liquid is injected into the liquid tank 5 through the liquid inlet pipe 51. When the flue gas generated during processing is extracted, some flue gas will impact the liquid surface in the liquid tank 5 with the airflow, and the particulate matter in this part of the flue gas will fall into the liquid and be wetted. Only the impurities in the other part of the flue gas will be filtered by the activated carbon filter plate 32. Through the above structure, the activated carbon filter plate 32 can be cleaned at a longer interval, improving the ease of use of the device.

[0029] like Figures 1 to 4 As shown, a plurality of support rods 6 are fixedly connected to the middle of the elastic membrane 23; the two ends of the plurality of support rods 6 are respectively located inside a pair of sliding grooves 21; during operation, as the sliding frame 22 moves, the pair of elastic membranes 23 will contract and expand respectively. The middle of the contracted elastic membrane 23 will not sag excessively due to the arrangement of the plurality of support rods 6. Through the above structure, the occurrence of large gaps at the edge of the elastic membrane 23 caused by excessive sag in the middle of the elastic membrane 23 can be reduced, thus reducing the air intake effect.

[0030] like Figure 4 As shown, both ends of the support rod 6 are rotatably connected to rollers 7; the rollers 7 are located inside the slide groove 21; through the above structure, the sliding friction between the support rod 6 and the slide groove 21 can be transformed into rolling friction, reducing the wear of the component and improving the service life of the component.

[0031] During operation, when the workpiece is laser-cut or welded by the fiber laser 12, the workpiece will be heated, melt, evaporate, or burn, generating a certain amount of fumes. At this time, the exhaust fan 15 is started to extract the fumes. Some of the fumes generated during workpiece processing will enter the waste discharge tank 14 through the cutting groove 13 and guide hole 16 with the airflow and be treated by the filter assembly. Then the treated gas enters the exhaust fan 15 and is discharged. When laser cutting or welding the workpiece, the motor drives the lead screw 2 to rotate, thereby driving the sliding frame 22 to move with the fiber laser. The laser 12 moves, allowing the sliding frame 22 to move with the laser irradiation position during workpiece processing. During evacuation, a negative pressure is created inside the cutting groove 13, causing the ends of a pair of elastic membranes 23 to adhere to the bottom of the sliding groove 21. At this time, most of the upward-flowing gas enters the cutting groove 13 through the sliding frame 22, thus concentrating the suction force. When the activated carbon filter plate 32 needs cleaning or replacement, the mounting frame 31 is slid out from inside the machine body 1, and then the activated carbon filter plate 32 is cleaned or replaced. After replacement, slide the mounting frame 31 into the machine body 1 along the placement groove 3, and rotate the limiting rod 33 so that the bottom end of the limiting rod 33 hangs down naturally and blocks the side wall of the mounting frame 31, so that the mounting frame 31 will not easily slide. When it is necessary to replace the activated carbon filter plate 32, rotate the limiting rod 33 so that the limiting rod 33 no longer restricts the mounting frame 31. At this time, the mounting frame 31 will pop out from the machine body 1 under the elastic force of the spring 41. After cleaning is completed and the mounting frame 31 is slid into the machine body 1, the rubber pad 4 will fit tightly against the side wall of the machine body 1. To reduce the gap between the machine body 1 and the mounting frame 31, some liquid is injected into the liquid tank 5 through the liquid inlet pipe 51. When the flue gas generated during processing is extracted, some of the flue gas will impact the liquid surface in the liquid tank 5 with the airflow. The particulate matter in this part of the flue gas will fall into the liquid and be wetted. Only the impurities in the other part of the flue gas will be filtered by the activated carbon filter plate 32. As the sliding frame 22 moves, a pair of elastic membranes 23 will contract and expand respectively. The contracted elastic membranes 23 will not sag excessively in the middle due to the setting of multiple support rods 6.
