Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a laser cutting machine with an automatic slag removal function. Background Art

[0002] Laser cutting is a technology that uses a high-power density laser beam to irradiate materials, rapidly heat the materials to evaporate or melt, and uses high-speed airflow to blow the molten or vaporized materials away from the cutting area, thereby achieving precise cutting. It is an efficient and precise thermal cutting method widely used in modern industrial processing.

[0003] Existing laser cutting tables usually have multiple sword bars to support the workpiece and ensure the stability of the workpiece during the cutting process. Especially for thin plates or medium and thick plates, the evenly distributed sword bars can prevent the workpiece from being deformed or warped by force, ensuring cutting accuracy. However, when the laser cutting machine cuts the workpiece, the high-speed airflow will blow the slag downward, so there will be slag splashing on the surface of the sword bar. As the cutting work continues, the slag on the surface of the sword bar will continue to accumulate. When the slag on the surface of the sword bar accumulates too much, it will not only affect the flatness of the workpiece placement, resulting in reduced cutting accuracy, but also damage the structure of the sword bar. Therefore, it is necessary to manually use tools to clean the slag on the surface of each sword bar in turn on a regular basis. Such an operation is time-consuming and labor-intensive, and the cleaning efficiency is low. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment: A laser cutting machine with automatic slag removal function, such as Figure 1-Figure 7As shown, it includes a laser cutting machine body 1, which is composed of a workbench 101, a sword grid 102, a three-axis moving mechanism 103, a laser cutting head 104 and a baffle 106. A discharge port is opened on the upper right side of the workbench 101, and a plurality of sword grids 102 are evenly spaced and slidably connected to the upper right side of the workbench 101 and can slide up and down, and the plurality of sword grids 102 are all located at the discharge port of the workbench 101, the three-axis moving mechanism 103 is installed on the top surface of the workbench 101, and the laser cutting head 104 is installed on the three-axis moving mechanism 103. Square holes 105 are evenly spaced on both sides of the upper front and rear of the workbench 101, and a plurality of baffles 106 are spaced and connected to the front, back, left and right sides of the workbench 101, so that the workpiece to be processed can be stably placed on the plurality of sword grids The top surface of the sword fence 102 is then driven by a three-axis moving mechanism 103 to move the laser cutting head 104 in three directions, front and back, left and right, and up and down, so that the laser cutting head 104 can perform laser cutting on the workpiece on the top surface of the sword fence 102. During the cutting process, the generated slag and the cut workpiece can fall down through the discharge port of the workbench 101; it also includes a fixed shell 2 and a water supply mechanism, the fixed shell 2 is fixedly connected to the outside of the sword fence 102, the shape of the fixed shell 2 is similar to that of the sword fence 102, and a water supply channel 201 is opened inside the fixed shell 2, the fixed shell 2 is composed of a low prism portion 202 and a high prism portion 203, and a plurality of low prism portions 202 are arranged in a straight line along the front and back direction, and the left and right sides of the low prism portion 202 are inclined surfaces (with Figure 1 The directions marked are described), each adjacent two low prism portions 202 are connected with a high prism portion 203, the front, back, left, and right sides of the high prism portion 203 are all inclined surfaces, and the interior of the high prism portion 203 is connected with the interior of the adjacent low prism portion 202 through the water supply channel 201, the top surface of the low prism portion 202 is spaced apart with a plurality of through holes I 204, the through holes I 204 are connected with the water supply channel 201, the top surface of the high prism portion 203 is spaced apart with through holes II 205, the through holes II 205 are connected with the water supply channel 201, and the through holes II 205 are arranged in a rectangular shape, and the top surface of the high prism portion 203 is slightly lower than the top surface of the sword grid 102, so that the workpiece to be processed is placed on the sword. When the top surface of the sword grid 102 is formed, the bottom surface of the workpiece to be processed will not block the through hole II 205. The water supply mechanism is used to transport cold water to the water supply channel 201, so that the cold water can emerge through the through hole I 204 and the through hole II 205 and flow downward along the outer wall of the fixed shell 2 to form a water curtain on the outer wall of the fixed shell 2. Then the laser cutting machine body 1 is controlled to perform laser cutting on the workpiece. When the slag splashes onto the water curtain, it can be directly cooled and solidified and fall down. In this way, the slag can be prevented from accumulating on the surface of the sword grid 102, thereby ensuring the flatness of the workpiece and then ensuring the cutting accuracy. The structure of the sword grid 102 will not be damaged, and there is no need to manually clean the surface of the sword grid 102, saving time and effort.

[0030] like Figure 5-Figure 7As shown, the water supply mechanism includes a water storage frame 3, a water pump Ⅰ4, a water supply pipe 5, a wave pump 6, a discharging assembly and a screening assembly. The water storage frame 3 is arranged below the sword fence 102 so that the slag and the workpiece dropped by cutting can directly fall down into the water storage frame 3. The water pump Ⅰ4 is symmetrically connected to the front and rear sides of the water storage frame 3, and the water inlet of the water pump Ⅰ4 is connected to the water storage frame 3. The two ends of the water supply pipe 5 are respectively connected to the water supply channel 201 and the water outlet of the water pump Ⅰ4, so that the water pump Ⅰ4 can transport the cold water in the water storage frame 3 to the water supply channel 201 through the water supply pipe 5. The wave pump 6 is installed on the left side of the inner wall of the water storage frame 3 The discharging assembly is used to discharge the slag and the workpieces dropped by cutting in the water storage frame 3, and then the screening assembly can screen the slag and the workpieces dropped by cutting; the discharging assembly includes a conveyor 7, a rotating brush 8 and a pulley assembly 9, the conveyor 7 is installed in the water storage frame 3, and the conveyor 7 is inclined with the left lower and the right higher, and a space for discharging slag and the workpieces dropped by cutting is reserved between the bottom surface of the baffle 106 on the right side and the top surface of the conveyor 7, the rotating brush 8 is rotatably connected to the upper right side of the water storage frame 3, and the bristles of the rotating brush 8 are in contact with the conveyor belt surface of the conveyor 7, and the pulley assembly Component 9 is composed of two pulleys and a flat belt. The two pulleys are respectively connected to the front end of the rotating brush 8 and the front end of one of the conveying wheels of the conveyor 7. The flat belt is wound around the two pulleys so that the rotating brush 8 and the conveyor 7 can be transmitted through the pulley assembly 9. The rotating brush 8 can brush and clean the conveyor belt surface of the conveyor 7; the screening assembly includes a mounting frame 10, a collecting frame 11, a brushless motor 12, a rotating cylinder 13 and a connecting ring 14. The mounting frame 10 is connected to the right side of the water storage frame 3. The shape of the mounting frame 10 is a U-shape with an opening facing backwards, and the mounting frame 1 0 is located below the rotating brush 8, so that the conveyor 7 can transport the slag in the water storage frame 3 and the workpieces dropped by cutting to the installation frame 10, the collecting frame 11 is placed below the installation frame 10, and a plurality of brushless motors 12 are evenly installed on the inner side of the installation frame 10, the rotating cylinder 13 is connected to the brushless motor 12, and the connecting rings 14 are evenly connected to the rotating cylinder 13, so that the brushless motor 12 drives the rotating cylinder 13 and the connecting ring 14 to rotate, and the workpieces dropped by cutting can be transported backward for discharging, and the slag can fall down into the collecting frame 11 through the gap between two adjacent connecting rings 14.

[0031] First, put an appropriate amount of cold water into the water storage frame 3, and then the cold water in the water storage frame 3 can be transported to the water supply channel 201 in each fixed shell 2 through the water pump Ⅰ4 and the water supply pipe 5, and the water in the water supply channel 201 can flow to the through hole Ⅰ204 and the through hole Ⅱ205 respectively, and the cold water emerging from the through hole Ⅰ204 can flow downward along the inclined surfaces on the left and right sides of the low prism part 202, and the cold water emerging from the through hole Ⅱ205 can flow downward along the inclined surfaces on the front, back, left and right sides of the high prism part 203, so that a water curtain flowing downward can be formed on the outer wall of the fixed shell 2, and the water curtain on the outer wall of the fixed shell 2 can eventually fall down into the water storage frame 3 for reuse; then the workpiece to be processed can be placed on the top surface of the sword fence 102 manually, because the top surface of the high prism part 203 is slightly lower On the top surface of the sword grid 102, the bottom surface of the workpiece will not block the top of the through hole II 205, thereby ensuring that there is a water curtain that continuously flows downward on the outer wall of the fixed shell 2, and then the workpiece placed on the top surface of the sword grid 102 can be laser cut by the laser cutting machine body 1, and the cut workpiece can pass through between the two sword grids 102, and then fall down into the water storage frame 3 through the discharge port of the workbench 101, and at the same time, the slag generated during the cutting process will be blown downward, so that the slag will directly fall into the cold water in the water storage frame 3 for cooling and solidification, and the slag splashed on the outside of the fixed shell 2 will also be quickly cooled and solidified by the water curtain, and finally fall down into the water storage frame 3, so that the slag can be prevented from accumulating on the surface of the sword grid 102, thereby ensuring the flatness of the workpiece placement, thereby ensuring The cutting accuracy is ensured without damaging the structure of the sword fence 102, and there is no need to manually clean the surface of the sword fence 102, which saves time and effort; at the same time, during the laser cutting process, when the laser emitted by the laser cutting head 104 completely penetrates the workpiece, it will directly irradiate the water surface in the water storage frame 3, so the wave-making pump 6 can be used to form water waves on the water surface in the water storage frame 3 to prevent the water surface from vertically reflecting the laser emitted by the laser cutting head 104, thereby preventing the focusing mirror or other optical elements in the laser cutting head 104 from being damaged, and the baffle 106 can block the laser that is scattered by the water waves; when the slag in the water storage frame 3 needs to be processed, the slag in the water storage frame 3 and the workpiece dropped by the cutting can be transported to the right by the conveyor 7, Since the conveyor 7 is arranged at an angle, the cold water in the water storage frame 3 will not be transported out. At the same time, the conveyor 7 can drive the rotating brush 8 to rotate through the pulley assembly 9. The rotating brush 8 can brush and clean the conveyor belt surface of the conveyor 7 to prevent slag and cut workpieces from adhering to the conveyor belt surface of the conveyor 7 due to the tension of the water, so that the slag and the cut workpieces can fall into the installation frame 10, and then the brushless motor 12 drives the rotating cylinder 13 and the connecting ring 14 to rotate, so that the cut workpieces in the installation frame 10 can be transported backwards, which is convenient for manual unified collection and recycling. The slag in the installation frame 10 will fall down through the gap between the two adjacent connecting rings 14 to the collecting frame 11 for collection, which is convenient for manual unified collection and processing.

[0032] like Figure 8 As shown, the laser cutting machine with automatic slag removal function also includes a vibration component, which includes a connecting plate 15, a supporting spring 16, a mounting block 17, an electric push rod 18, a mounting plate 19, a strong magnet 20 and a vibration motor 21. The two connecting plates 15 are symmetrically connected to the workbench 101 front and back, the bottom surface of the connecting plate 15 is connected to four supporting springs 16, and the lower ends of the four supporting springs 16 are connected to the mounting block 17, the electric push rod 18 is connected to the mounting block 17, the top surface of the telescopic rod of the electric push rod 18 is in contact with the bottom surface of the connecting plate 15, the two mounting blocks 17 are connected to the mounting plate 19 on the side close to each other, the strong magnets 20 are evenly spaced and connected to the top surface of the mounting plate 19, the strong magnets 20 correspond to the sword grid 102 one by one, and the strong magnets 20 are all located directly below the corresponding sword grid 102, and the vibration motor 21 is symmetrically installed on the side of the mounting plate 19.

[0033] Initially, the support spring 16 is in a stretched state, and the strong magnet 20 is in a separated state from the sword grid 102, so that the bottom surface of the sword grid 102 is in contact with the workbench 101, thereby ensuring the stability of the sword grid 102; since the top surface of the low prism portion 202 and the top surface of the high prism portion 203 are both planes, the slag splashed on the top surface of the low prism portion 202 and the top surface of the high prism portion 203 will also remain on the top surface of the low prism portion 202 and the top surface of the high prism portion 203 after being cooled by the water curtain; when the workpiece is cut, the telescopic rod of the electric push rod 18 can be controlled to shorten, and at this time the support spring 16 can return to its original state, and the support spring 1 6 can drive the mounting block 17, the cylinder body of the electric push rod 18, the mounting plate 19, the strong magnet 20 and the vibration motor 21 to move upward. When the strong magnet 20 contacts the sword fence 102, the strong magnet 20 will be adsorbed on the bottom surface of the sword fence 102 due to the magnetic force, and the strong magnet 20 will push the sword fence 102 to move upward for a distance, so that the bottom surface of the sword fence 102 is separated from the workbench 101, until the telescopic rod of the electric push rod 18 is shortened to be separated from the bottom surface of the connecting plate 15, and then the mounting plate 19 can be driven by the vibration motor 21 to vibrate up and down, and the mounting plate 19 can drive the sword fence 102 to move up and down through the strong magnet 20. The vibration of the up and down reciprocating motion can shake off the slag remaining on the top surface of the low prism part 202 and the top surface of the high prism part 203, so that the slag can fall into the water storage frame 3. During the vibration of the mounting plate 19, the support spring 16 can adaptively deform to prevent the workbench 101 from vibrating and ensure the stability of the workbench 101. Then the vibration motor 21 can be turned off, and the telescopic rod of the electric push rod 18 can be controlled to extend until the top surface of the telescopic rod of the electric push rod 18 contacts the bottom surface of the connecting plate 15. The telescopic rod of the electric push rod 18 continues to extend, which can drive the mounting block 17 to move downward, and the support spring 16 is stretched. The mounting block 17 can drive the cylinder body, mounting plate 19, strong magnet 20 and vibration motor 21 of the electric push rod 18 to move downward and reset, and the strong magnet 20 can drive the sword grid 102 to move downward and reset, so that the bottom surface of the sword grid 102 contacts the workbench 101 again, and the sword grid 102 stops moving downward, and then the mounting plate 19 and the strong magnet 20 continue to move downward, so that the strong magnet 20 can be separated from the sword grid 102; during the laser cutting process of the workpiece, the entire vibration assembly does not work, so the sword grid 102 does not vibrate, which can keep the workpiece placed on the top surface of the sword grid 102 stable, thereby ensuring the accurate cutting of the workpiece.

[0034] like Figure 9-11As shown, the laser cutting machine with automatic slag removal function also includes a removal component, which includes a mounting frame 22, a blower 23, an air gathering frame 24 and an exhaust unit 25. The mounting frame 22 is connected to the rear side of the workbench 101, the blower 23 is connected to the mounting frame 22, the air gathering frame 24 is connected to the rear side of the workbench 101, and the front and rear sides of the air gathering frame 24 are respectively connected to the square hole 105 on the rear side and the air outlet of the blower 23, the exhaust unit 25 is connected to the front side of the workbench 101, and the air inlet of the exhaust unit 25 is connected to the square hole 105 on the front side; The laser cutting machine with automatic slag removal function The cutting machine also includes a condensing mechanism, which includes a water storage tank 26, a water level gauge 27, a connecting cover 28, a heat sink 29, a condensing pipe 30, an inclined platform 31 and a reflux component. The water storage tank 26 is arranged on the front side of the workbench 101, the water level gauge 27 is installed on the right side of the water storage tank 26, the connecting cover 28 is connected to the rear side of the top surface of the water storage tank 26, the bottom surface of the connecting cover 28 is connected to the top surface of the water storage tank 26, and the rear side of the connecting cover 28 is connected to the air outlet of the exhaust unit 25, a plurality of heat sinks 29 are connected to the inside of the connecting cover 28 at intervals, and the condensing pipe 30 is connected to the plurality of heat sinks 29 in an S shape (such as Fig.11 As shown), the two ends of the condenser 30 are respectively connected to the water storage frame 3 and the water supply pipe 5 on the front side, the inclined platform 31 is connected to the front side of the top of the water storage tank 26, the top surface of the inclined platform 31 is a slope that is high in the front and low in the back, and the reflux component is used to transport the water in the water storage tank 26 to the water storage frame 3; the reflux component includes a water pump II 32 and a reflux pipe 33, the water pump II 32 is installed on the right side of the water storage tank 26, and the water inlet of the water pump II 32 is connected to the water storage tank 26, and the two ends of the reflux pipe 33 are respectively connected to the water outlet of the water pump II 32 and the water storage frame 3.

[0035] When the slag is cooled and solidified by cold water, the cold water absorbs heat and evaporates, which may produce water vapor, thereby affecting the normal operation of the laser cutting head 104; therefore, when the laser cutting machine body 1 is laser cutting the workpiece, the hair dryer 23 and the exhaust fan unit 25 can be started. Under the action of the wind gathering frame 24, the hair dryer 23 can blow air toward the discharge port of the workbench 101, and the exhaust fan unit 25 can quickly discharge the air at the discharge port of the workbench 101 forward, so that a continuous forward-flowing airflow can be formed at the discharge port of the workbench 101. When the cold water absorbs heat and evaporates to generate water vapor, the water vapor can be quickly discharged forward into the connecting cover 28 to prevent the water vapor from floating upward to the surrounding of the laser cutting head 104; and the heat sink 29 can absorb the water vapor in the connecting cover 28 The heat of the air causes the water vapor to condense into water, and the water will fall down into the water tank 26. Since there is a forward airflow at the connecting cover 28, water will be blown to the top surface of the inclined platform 31, and then flow backward along the top surface of the inclined platform 31 into the water tank 26. The water level gauge 27 can monitor the water level in the water tank 26. At the same time, the cold water in the front water supply pipe 5 can be transported to the condenser 30. The cold water in the condenser 30 can absorb the heat of the heat sink 29, so that the heat sink 29 can be used continuously and absorb the heat of the water vapor, and the cold water in the condenser 30 will eventually flow into the water storage frame 3 for recycling. When a certain amount of water is stored in the water tank 26, the water in the water tank 26 can be transported to the water storage frame 3 for recycling through the water pump II 32 and the reflux pipe 33.
