Description

Technical Field

[0001] This invention relates to the field of laser cutting, and more particularly to a high-precision CNC laser cutting machine for metal processing. Background Technology

[0002] In the field of metal processing, laser cutting technology has become an indispensable processing method due to its advantages such as high precision and high efficiency. With the continuous improvement of industrial development's requirements for the quality and processing accuracy of metal products, the demand for high-precision CNC laser cutting machines is growing daily. However, traditional laser cutting machines have many problems in practical applications. On the one hand, the cutting process generates a large amount of smoke and dust, which not only pollutes the surrounding working environment and harms the health of operators, but may also adhere to the surface of the equipment, affecting its normal operation and accuracy, and reducing its service life. Moreover, the smoke and dust diffuses into the air, which does not comply with increasingly stringent environmental protection requirements, putting environmental pressure on enterprises. On the other hand, as the core component of a laser cutting machine, the laser cutting head experiences accelerated wear due to the continuous high temperatures during the cutting process. High temperatures can lead to a decline in the performance of internal components of the cutting head, causing problems such as thermal deformation, which in turn affects cutting accuracy and quality, shortens the lifespan of the cutting head, and increases the company's equipment maintenance and replacement costs. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision CNC laser cutting machine for metal processing. This laser cutting machine adopts a sealed design, which can prevent smoke and dust from spreading into the surrounding environment during actual use, thereby improving its environmental performance. In addition, it can continuously cool the cutting head, thus extending the service life of the cutting head.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-precision CNC laser cutting machine for metal processing includes a base, with a housing fixedly connected to the upper end of the base and multiple casters fixed to the lower end of the base; a limiting mechanism, including a vertical plate fixedly connected to the upper end of the base, a mounting bracket fixedly connected to the left side of the vertical plate, a drive motor mounted on the mounting bracket, the output shaft of the drive motor passing through the vertical plate and fixedly connected to a three-jaw chuck; a cutting mechanism, including an electric slide rail fixedly connected to the top of the housing, a slide rail seat slidably connected to the sliding part of the electric slide rail, and a laser cutting head mounted at the lower end of the slide rail seat; and an exhaust gas treatment mechanism for centralized treatment of welding exhaust gas, improving the environmental performance of the cutting machine.

[0005] Preferably, a sealing door is installed on the front side of the housing, a transparent observation window is installed at the sealing door, and a handle is installed on the sealing door.

[0006] Preferably, the waste gas treatment mechanism includes a treatment chamber opened inside the base, the treatment chamber being filled with waste gas treatment liquid, the inner bottom space of the housing being connected to the inner bottom space of the treatment chamber through a vertical connecting pipe, an exhaust fan being installed on the right side of the base, the air inlet end of the exhaust fan being connected to an exhaust pipe, and the other end of the exhaust pipe extending to the inner top of the treatment chamber.

[0007] Preferably, a hollow plate is fixedly connected to the bottom of the processing cavity, and a plurality of diversion holes are opened on the top of the hollow plate. The lower end of the vertical connecting pipe extends into the interior of the hollow plate.

[0008] Preferably, a drain port is provided on the front side of the bottom of the processing chamber, and a manual valve is installed inside the drain port.

[0009] Preferably, a rotating shaft is rotatably connected to the inner top of the processing chamber, and a plurality of stirring rods are fixedly connected to the outer side of the rotating shaft, with the upper end of the rotating shaft extending into the interior of the housing.

[0010] Preferably, a gearbox is installed on the right side of the vertical plate, the output shaft of the gearbox is fixedly connected to a second bevel gear, a first bevel gear is installed at the upper end of the rotating shaft, the first bevel gear meshes with the second bevel gear, the input shaft of the gearbox passes through the vertical plate, and pulleys are installed on both the input shaft of the gearbox and the output shaft of the drive motor, and the two pulleys are connected by a transmission belt.

[0011] Preferably, the inner top of the housing has a strip-shaped opening, a horizontal plate is fixedly connected to the front side of the slide rail seat, an air inlet square tube is fixedly connected to the upper end of the horizontal plate, the upper end of the air inlet square tube passes through the strip-shaped opening, the front and rear sides of the air inlet square tube respectively contact the front and rear inner walls of the strip-shaped opening and are slidably connected, sealing plates are fixedly connected to the left and right sides of the air inlet square tube, the lower ends of the two sealing plates contact the upper end surface of the housing and are slidably connected, and a folded tube communicating with the air inlet square tube is fixedly connected to the lower end of the horizontal plate.

[0012] Compared with the prior art, the beneficial effects of this invention are as follows: 1. With multiple casters at the bottom of the base, the laser cutting machine can be easily moved to a suitable working position without complicated equipment handling procedures, greatly saving manpower and time costs, improving equipment deployment efficiency, and adapting to the needs of different working scenarios.

[0013] 2. A three-jaw chuck, in conjunction with a drive motor, is used to limit and fix tubular workpieces. Operation is simple and convenient, and the fixation effect is stable. Starting the drive motor rotates the workpiece, and in conjunction with the laser cutting head, precise cutting operations can be achieved, improving processing accuracy and efficiency.

[0014] 3. The exhaust gas generated during cutting enters the hollow plate through a vertical connecting pipe, and is then evenly dispersed into the exhaust gas treatment liquid in the treatment chamber through diversion holes, achieving efficient exhaust gas treatment. At the same time, the exhaust fan creates negative pressure in the treatment chamber to ensure that the exhaust gas is fully collected, improving the environmental performance of the cutting machine.

[0015] 4. The drive motor drives the gearbox via pulleys and a transmission belt. The gearbox output shaft drives the rotating shaft to rotate, which in turn causes the agitator to agitate the waste gas treatment liquid. Agitation increases the contact area between the waste gas and the treatment liquid, improving the waste gas treatment effect and reducing the emission of harmful gases.

[0016] 5. When a negative pressure is created inside the housing, gas is supplied through the air inlet square tube and folded tube. This supplied gas is then blown towards the laser cutting head to cool it down. This effectively reduces wear on the cutting head caused by high temperatures, extends its service life, and reduces equipment maintenance costs. Attached Figure Description

[0022] In this invention, the laser cutting machine can be moved to a suitable working position by means of multiple casters 2 at the lower end of the base 1. The tubular workpiece to be processed is placed at the three-jaw chuck. The drive motor 21 on the mounting frame 20 is started.

Multiple stirring rods 16 on the outside of the rotating shaft 15 agitate the exhaust gas treatment liquid inside the processing chamber 12, improving the exhaust gas treatment effect. When a negative pressure is generated inside the housing 4, gas will be replenished through the air inlet square tube 5 and the folded tube 30. The replenished gas will be blown towards the laser cutting head 29 to cool it down and ensure its service life. After prolonged use, the waste liquid can be discharged by opening the manual valve in the drain port 3 at the bottom front of the treatment chamber 12.
