Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a laser beveling device. Background Technology

[0002] A laser beveling device is a piece of equipment that uses laser technology for precise cutting and beveling. It mainly consists of a laser source, an optical system, a control system, a workpiece support system, and a fume extraction system. It uses a laser beam to irradiate the surface of the workpiece with high energy, causing a localized area of ​​the workpiece to heat up, evaporate, or melt instantly, thereby achieving cutting and beveling.

[0003] A search revealed that Chinese patent application CN222511419U discloses a laser beveling device, which mainly adjusts the cutting angle by rotating a drive motor, a rotating shaft, a turntable, a first motor, and a first gear, making the cutting more flexible.

[0004] Compared with existing technologies in related fields, it can be seen that most of the nozzles of existing laser cutting devices directly spray air. When cutting thick workpieces, there is a problem that molten slag cannot be cleaned in a timely and effective manner, resulting in adhesion and affecting cutting quality and efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a laser beveling device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A laser beveling device includes a frame and a laser cutting mechanism. A feeding mechanism and an adjustment mechanism for adjusting the cutting position and angle of the laser cutting mechanism are fixedly installed on the frame. A worktable is fixedly installed on the feeding mechanism. The laser cutting mechanism is fixedly installed on the adjustment mechanism. An air blowing unit and a fixed seat are fixedly installed on the laser cutting mechanism.

[0008] The air blowing unit includes an air inlet valve and an annular air guide seat. The air inlet valve is fixedly installed on the side of the laser cutting mechanism. The laser cutting mechanism and the fixed seat are provided with an installation cavity, an air guide cavity, and an air outlet. The surface of the fixed seat is fixedly installed with a drive assembly and a first nozzle. There are three installation cavities. The first gas distributor, the second gas distributor, and the third gas distributor, which are connected to the air guide cavity, are fixedly installed in the three installation cavities respectively. The annular air guide seat is rotatably installed on the laser cutting mechanism, the fixed seat, and the third gas distributor. A second nozzle is fixedly installed on the annular air guide seat. The first gas distributor is connected to the air outlet, and the second gas distributor is connected to the first nozzle. The second nozzle is located in the middle of the air outlet and the first nozzle.

[0009] Furthermore, the drive assembly includes a micro motor and a gear ring. The micro motor is fixedly mounted on the laser cutting mechanism. The output shaft of the micro motor is rotatably connected to the laser cutting mechanism. A gear is fixedly mounted on the output shaft of the micro motor. The gear ring is fixedly mounted on the annular air guide seat. The gear ring meshes with the gear. The gear and the gear ring are located in the mounting cavity.

[0010] Furthermore, a pressure sensor is fixedly installed inside the air delivery chamber.

[0011] Furthermore, an electric heating mechanism is fixedly installed inside the air guide cavity.

[0012] Furthermore, a collection hopper is fixedly installed on the frame, located below the workbench, and a collection box is installed at the lower end of the collection hopper, with the collection box slidably installed on the frame.

[0013] Furthermore, the workbench features a hollow design, with the hollowed-out portion corresponding to the collection hopper.

[0014] Furthermore, vibration motors are fixedly installed at both ends of the collection hopper.

[0015] The advantages compared to existing technologies are as follows:

[0016] 1. During the cutting operation, the first nozzle forms an air curtain to block molten slag from splashing, and the air outlet sprays air to assist cutting and blow away molten slag. Through a micro motor, gears, and gear ring, the second nozzle blows the molten slag at multiple angles, making it easier to remove the molten slag, reducing the adhesion of molten slag to the workpiece and the pollution on site, improving the quality and efficiency of molten slag cleaning, and ensuring the cutting quality.

[0017] 2. The gas used during cutting is heated by an electric heating mechanism, which reduces the temperature loss at the cutting position, improves the cutting efficiency of the laser cutting mechanism on the workpiece, and reduces the generation of molten slag. At the same time, when the heated gas blows the molten slag, it can reduce the cooling of the molten slag, reduce the viscosity and adhesion of the molten slag, and make the molten slag easier to blow out of the cutting position, ensuring the flatness and smoothness of the cutting surface, and improving the molten slag cleaning effect and cutting quality.

[0028] like Figures 1-7As shown, a laser beveling device includes a frame 1 and a laser cutting mechanism 7. A feeding mechanism 2 and an adjustment mechanism 5 for adjusting the cutting position and angle of the laser cutting mechanism 7 are fixedly installed on the frame 1. A worktable 4 is fixedly installed on the feeding mechanism 2, and the laser cutting mechanism 7 is fixedly installed on the adjustment mechanism 5. An air blowing unit and a fixed base 6 are fixedly installed on the laser cutting mechanism 7. The workpiece to be cut is placed on the worktable 4. The feeding mechanism 2 moves the workpiece via the worktable 4, so that the position to be cut on the workpiece is moved to the position between the laser cutting mechanism 7 and the adjustment mechanism 5. The transverse cutting position of the workpiece is adjusted by the feeding mechanism 2, and the laser cutting mechanism 7 is moved by the adjustment mechanism 5, thereby adjusting the tilt angle and longitudinal position of the laser cutting mechanism 7 during cutting. The laser cutting mechanism 7 performs beveling on the workpiece. During the cutting process, the air blowing unit blows air at the cutting position to blow out the molten slag generated during cutting, reducing adhesion and ensuring cutting quality.

[0029] like Figures 2-6As shown, the air blowing unit includes an air inlet valve 301 and an annular air guide seat 311. The air inlet valve 301 is fixedly installed on the side of the laser cutting mechanism 7. The laser cutting mechanism 7 and the fixed seat 6 are provided with an installation cavity, an air guide cavity 302, and an air outlet 304. The air outlet 304 is arranged around the laser cutting mechanism 7, and the air outlet center of the air outlet 304 corresponds to the laser of the laser cutting mechanism 7. The surface of the fixed seat 6 is fixedly installed with a drive assembly and a first nozzle 306. There are three installation cavities. The first gas distributor 303, the second gas distributor 305, and the third gas distributor 310, which are connected to the air guide cavity 302, are fixedly installed in the three installation cavities respectively. The annular air guide seat 311 is rotatably installed on the laser cutting mechanism 7, the fixed seat 6, and the first air guide cavity 302. On the three-gas splitter 310, a second nozzle 312 is fixedly installed on the annular gas guide seat 311. The first gas splitter 303 is connected to the gas outlet 304, and the second gas splitter 305 is connected to the first nozzle 306. The second nozzle 312 is located between the gas outlet 304 and the first nozzle 306. The inlet valve 301 is connected to an external gas delivery device. When the laser cutting mechanism 7 performs cutting operations, the external gas delivery device delivers gas to the gas guide chamber 302 through the inlet valve 301, and then disperses the gas through the gas guide chamber 302 into the first gas splitter 303, the second gas splitter 305, and the third gas splitter 310. Ten gas streams are split to ensure uniform airflow. The second gas splitter 305 evenly distributes the gas into the first nozzle 306, which then ejects the gas. The airflow ejected from the first nozzle 306 forms an air curtain around the cutting position, blocking molten slag during the cutting process. This effectively reduces slag splashing, minimizes environmental pollution caused by slag splashing, improves safety and ease of slag collection and disposal, and isolates the gas from external air, reducing the impact of external air oxidation on cutting quality. The first gas splitter 303 evenly distributes the gas into the exhaust port 304, which then ejects the gas. The airflow ejected from the exhaust port 304 directly acts on the laser cutting position. The laser assists the laser cutting mechanism 7 in cutting the workpiece. Simultaneously, it blows out the molten slag generated during cutting from the cutting position. As the molten slag flies out, the gas in the third gas distributor 310 is evenly dispersed into the second nozzle 312 on the annular gas guide seat 311 and sprayed out through the second nozzle 312, thereby blowing the blown-out molten slag again. At the same time, the driving component drives the annular gas guide seat 311 and the second nozzle 312 to rotate, so that the airflow sprayed from the second nozzle 312 blows the molten slag from different angles. The swinging of the airflow during rotation makes the molten slag easier to fall off, improving the cleaning effect, effectively reducing the adhesion of molten slag on the workpiece, reducing the amount of cleaning work, and improving the quality and efficiency of workpiece cutting.

[0030] like Figure 2, Figure 3 , Figure 6 As shown, the drive assembly includes a micro motor 307 and a gear ring 309. The micro motor 307 is fixedly mounted on the laser cutting mechanism 7. The output shaft of the micro motor 307 is rotatably connected to the laser cutting mechanism 7. A gear 308 is fixedly mounted on the output shaft of the micro motor 307. The gear ring 309 is fixedly mounted on the annular air guide seat 311. The gear ring 309 meshes with the gear 308. The gear 308 and the gear ring 309 are located in the mounting cavity. During the cutting operation, the micro motor 307 drives the gear 308 to rotate, and the gear 308 drives the gear ring 309 to drive the annular air guide seat 311 to rotate, thereby adjusting the blowing position of the second nozzle 312, so that the molten slag is blown at different positions to ensure the cleaning effect of the molten slag.

[0031] like Figure 6 As shown, a pressure sensor 8 is fixedly installed inside the air guide cavity 302. The pressure sensor 8 can monitor the pressure of the airflow inside the air guide cavity 302 in real time, and thus control the pressure of the airflow by detecting the pressure.

[0032] like Figure 6 As shown, an electric heating mechanism 9 is fixedly installed inside the gas guide cavity 302. The electric heating mechanism 9 heats the gas passing through the gas guide cavity 302, increasing the gas temperature. When the heated gas is blown toward the cutting position, it reduces the temperature loss at the cutting position, improves the cutting efficiency of the laser cutting mechanism 7 on the workpiece, and reduces the generation of molten slag. At the same time, when the heated gas blows the molten slag, it can reduce the cooling of the molten slag, reduce the viscosity and adhesion of the molten slag, making it easier for the molten slag to be blown away from the cutting position, ensuring the flatness and smoothness of the cutting surface, and improving the molten slag cleaning effect and cutting quality.

[0033] like Figure 7 As shown, a collection hopper 11 is fixedly installed on the frame 1. The collection hopper 11 is located below the workbench 4. A collection box 12 is installed at the lower end of the collection hopper 11. The collection box 12 is slidably installed on the frame 1. When cutting, the collection box 12 is installed in place and fixed. The molten slag produced by cutting falls into the collection hopper 11 for collection. The molten slag is then discharged from the collection hopper 11 into the collection box 12 for collection, which facilitates subsequent processing of the molten slag and effectively improves work efficiency.

[0034] like Figure 1 , Figure 7 As shown, the workbench 4 has a hollow design, and the hollow part of the workbench 4 corresponds to the collection hopper 11. During the cutting process, slag falls onto the workbench 4. Due to the hollow design of the workbench 4, the slag on the workbench 4 falls into the collection hopper 11, which improves the convenience of slag collection and processing.

[0035] like Figure 7As shown, vibration motors 10 are fixedly installed at both ends of the collection hopper 11. After cutting, the vibration motors 10 are started, and the collection hopper 11 is vibrated by the vibration motors 10. The vibration causes the slag adhering to the collection hopper 11 to fall off, ensuring that the slag can smoothly enter the collection box 12 for collection, improving the effect and speed of slag collection, and reducing the amount of cleaning work.

[0036] Working principle: such as Figure 1 , Figure 7 As shown, the workpiece to be cut is placed on the worktable 4. The feeding mechanism 2 moves the workpiece through the worktable 4 to adjust the lateral position of the workpiece. The adjustment mechanism 5 moves the laser cutting mechanism 7 to adjust the tilt angle and longitudinal position of the laser cutting mechanism 7 during cutting, so that the laser cutting mechanism 7 can perform bevel cutting on the workpiece as needed.

[0037] like Figures 2-6 As shown, during the laser cutting mechanism 7's workpiece cutting process, the external gas supply device delivers gas to the gas guide chamber 302 through the gas inlet valve 301. The electric heating mechanism 9 heats the gas passing through the gas guide chamber 302 to increase the gas temperature. The pressure sensor 8 can monitor the air pressure in the gas guide chamber 302 in real time and adjust the gas pressure as needed for control. After the airflow enters the gas guide chamber 302, it is then dispersed into the first gas distributor 303, the second gas distributor 305, and the third gas distributor 310.

[0038] like Figure 4 , Figure 6 As shown, the second gas distributor 305 evenly disperses the gas into the first nozzle 306 and ejects it through the first nozzle 306. The airflow ejected through the first nozzle 306 forms an air curtain around the cutting position. The first gas distributor 303 evenly disperses the gas into the air outlet 304 and ejects it through the air outlet 304. The airflow ejected through the air outlet 304 directly acts on the laser cutting position to assist the laser of the laser cutting mechanism 7 in cutting the workpiece. At the same time, it blows the molten slag generated during cutting out of the cutting position. The air curtain formed by the airflow ejected through the first nozzle 306 blocks the molten slag and prevents splashing.

[0039] At the same time, such as Figures 2-4 , Figure 6 As shown, the micro motor 307 drives the gear 308 to rotate, and the gear 308 drives the gear ring 309 to rotate the annular air guide seat 311 and the second nozzle 312. The gas in the third gas distributor 310 is evenly dispersed into the second nozzle 312 on the annular air guide seat 311 and sprayed out through the second nozzle 312. This allows the airflow from the second nozzle 312 to blow the molten slag from different angles, reducing the adhesion of the molten slag to the workpiece.

[0040] like Figure 1 , Figure 7 As shown, during cutting, the slag enters the collection hopper 11 through the hollowed-out part on the workbench 4, and then enters the collection box 12 for collection, which facilitates the subsequent processing of the slag. At the same time, after the cutting is completed, the vibration motor 10 causes the collection hopper 11 to vibrate, which causes the slag adhering to the collection hopper 11 to fall off, thereby improving the slag collection effect.
