Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting device for processing metal workpieces. Background Technology

[0002] Metal workpieces are various parts made from metal materials such as steel and aluminum through processing. Laser cutting, as a common method for precision machining of metal workpieces, has advantages such as high processing efficiency and good cutting accuracy, and is widely used in the forming and processing of various metal parts.

[0003] In some factories, operators often neglect pretreatment and cleaning of the metal sheet surface during laser cutting. This is partly due to the perceived tediousness and time-consuming nature of the cleaning process, and partly due to a misconception that small amounts of oil or impurities have little impact on laser cutting. However, directly cutting metal sheets with oil and impurities not only interferes with the laser cutting path and affects positioning accuracy, but also generates black smoke, odors, and harmful gases when the laser heats the oil, posing risks to operator health, polluting the workshop environment, and creating slag and burrs at the cut, resulting in a rough and uneven cut surface, reducing finished product quality and processing pass rate. Furthermore, existing laser cutting equipment is ineffective at collecting metal waste and small debris generated during cutting. Small debris easily disperses, and the mixture of waste and debris makes sorting and collection difficult, leading to resource waste and increased on-site cleanup burden. Summary of the Invention

[0004] In order to overcome the shortcomings of existing laser cutting operations on metal sheets in some factories, such as operators neglecting to clean the surface of the metal sheets, resulting in oil and impurities remaining, which in turn leads to insufficient cutting positioning accuracy, generation of harmful fumes, poor cut quality, low finished product qualification rate, and poor collection of metal waste and fine debris, which are easy to disperse and are inconvenient to classify and recycle, the purpose of this invention is to provide a laser cutting device for metal workpiece processing.

[0015] Beneficial effects: 1. The electric slide rail drives the third moving plate to move laterally as a whole. In conjunction with the inclined nozzle spraying low-foaming emulsion metal-specific cleaning liquid to remove dirt, the first gear and the first rack mesh to drive the transmission, and link the first rotating shaft, the second gear, the third gear, the second rotating shaft and two sets of reciprocating screws to operate synchronously. This drives the fourth slider to drive the cleaning brush to reciprocate to rub and scrub, the air knife high-pressure airflow to blow and the arc scraper to scrape water and dry the plate surface. The multi-structure linkage operation realizes automatic oil removal, impurity removal and rapid drying pretreatment of the metal plate cutting surface. It avoids the interference of residual oil and impurities on the plate surface with the laser cutting optical path, prevents the generation of black smoke, odor and harmful gases during cutting, eliminates the problem of slag and burrs on the cut, and effectively improves the flatness of the cutting surface and the qualified rate of the finished product.

[0016] 2. This invention drives the bidirectional lead screw to rotate by rotating the handle rod, causing the first slider, the first moving plate, and the clamping plate to move synchronously towards each other in conjunction with the anti-slip pad. The first spring is compressed to form an elastic buffer flexible clamping structure, which works in concert to achieve precise centered positioning and stable clamping of the metal sheet. This avoids the edge compression and deformation of the metal sheet caused by traditional rigid clamping, and effectively counteracts the high-frequency vibration generated by laser cutting, preventing displacement and deviation during sheet processing, thus ensuring the basic accuracy of laser cutting positioning from the source.

[0017] 3. The hollow elongated shell moves synchronously with the laser cutting head via an electric slide carriage. The fourth gear meshes with the second rack to drive the third rotating shaft, fixed ring, and vibrating ball to rotate and impact the inclined guide plate to vibrate the material. Then, the dust extraction fan works in conjunction with the filter baffle to absorb the molten slag. The fourth electric push rod drives the filter baffle and elastic baffle to vibrate and remove the slag. The coordinated work of these components enables the automatic classification, collection, and unloading of laser cutting slag and scrap. This avoids the scattering of small debris and pollution of the workshop environment, prevents the accumulation of waste materials that may block the equipment channels, reduces the burden of manual cleaning on site, and facilitates the unified recycling and reuse of metal waste.

With the elastic buffering effect of the first spring 11, the clamping plate 12 forms a flexible clamping limit on the metal sheet, avoiding rigid compression that causes deformation of the metal sheet edge. At the same time, the reverse elastic force of the first spring 11, combined with the friction of the anti-slip pad 13, further improves the clamping firmness of the metal sheet and effectively counteracts the vibration generated during the laser cutting operation. The metal sheet to be laser-cut is then cleaned. The second electric push rod 32 is activated, and its output end drives the slide plate 33 and T-shaped rod 34 to move downward along the inner wall of the third moving plate 31. At the same time, the T-shaped rod 34 synchronously drives the third connecting rod 35, the first rectangular frame 36, the second rectangular frame 39, the air knife 58, and the arc-shaped scraper 59 to move downward. When the first rectangular frame 36 moves the first water storage chamber 37, the second water storage chamber 38, and the inclined nozzle 3701 close to the surface of the metal sheet, the output end of the second electric push rod 32 stops working. At this time, the first gear 45 is not engaged with the first rack 29. The electric slide rail 30 is activated, causing the third moving plate 31 to drive the first rectangular frame 36 and the second rectangular frame 39 to move synchronously. At the same time, the water pump 51 is activated, and water... The water inlet of pump 51 is connected to the corresponding first connecting pipe 52 via the first electrically controlled switching valve 53, thereby drawing the cleaning fluid from the first water tank 49. It is worth noting that the electrically controlled switching valve is existing technology. The first water tank 49 contains the cleaning fluid, which is a low-foaming emulsified metal-specific cleaning fluid. The second water tank 50 contains clean water. Then, the water outlet of pump 51 is connected to the corresponding second connecting pipe 54 via the second electrically controlled switching valve 5401, and the cleaning fluid is delivered to the first water storage chamber 37. It is then sprayed outward by the corresponding inclined nozzle 3701 to rinse the surface of the metal plate. The inclined spray of the cleaning fluid can wash away the impurities attached to the surface of the metal plate and fully dissolve the oil stains on the surface of the metal plate, making it easier for subsequent cleaning. When the third moving plate 31 moves to the end position of the electric slide rail 30, the third moving plate 31 stops moving, and the water pump 51 is turned off. The tilting nozzle 3701 stops working. At this time, the surface of the metal plate is uniformly coated with cleaning liquid. It is worth noting that when the metal plate is laser cut, the laser is focused on the upper surface for melting and cutting. The lower side is not the surface directly affected by the laser, and there is no beam irradiation or high-temperature melting reaction. Therefore, the impurities and oil stains attached there will not affect the cutting accuracy and cross-sectional quality. Therefore, there is no need to clean the lower side of the metal plate. Subsequently, the output end of the second electric push rod 32 drives the first rectangular frame 36 and the second rectangular frame 39 to move down again until the bottom of the first gear 45 contacts and meshes with the first rack 29. At the same time, the cleaning brush 43 adheres to the surface of the metal plate, and the silicone pad 42 is compressed and deformed. At this time, the electric slide rail 30 drives the third moving plate 31 to move in the opposite direction. The third moving plate 31 synchronously drives the first rectangular frame 36 and the second rectangular frame 39 to move in the opposite direction, causing the first gear 45 to mesh and rotate along the first rack 29. The rotation of the first gear 45 drives the first... A rotating shaft 44 rotates, which simultaneously drives a second gear 46 and one of the reciprocating lead screws 40 to rotate. The second gear 46 drives a third gear 47 and a second rotating shaft 48 to rotate through meshing transmission, which in turn drives another reciprocating lead screw 40 to rotate. The two reciprocating lead screws 40 are respectively threaded, which drive two intersecting fourth sliders 41 to move. The fourth sliders 41 simultaneously drive a rigid pressure plate 4101, a compressed silicone pad 42, and a cleaning brush 43 to move together. The cleaning brush 43 performs all-round reciprocating wiping and cleaning of the metal plate surface. Relying on the elastic adhesion of the silicone pad 42, it ensures close contact with the metal plate surface during the cleaning process, improving the cleaning adhesion and the decontamination effect. At the same time, through the synchronous linkage of the double reciprocating lead screws 40, a stable and uniform automated cleaning operation is achieved on the metal plate surface. During the wiping process, the cleaning brush 43 will generate cleaning foam on the metal plate surface. Relying on the cooperation of the reciprocating movement, the foam is evenly spread on the metal plate surface, which fully softens the attached oil and stubborn impurities. When the cleaning brush 43 moves to the end of the metal sheet, the third moving plate 31 moves forward again, and at the same time, the water pump 51 is started. The water inlet of the water pump 51 is connected to the corresponding first connecting pipe 52 through the first electrically controlled switching valve 53 to draw clean water from the second water tank 50. The water outlet of the water pump 51 is connected to the corresponding second connecting pipe 54 through the second electrically controlled switching valve 5401 to deliver the clean water to the second water storage chamber 38. The clean water is then sprayed outwards by the corresponding tilting nozzle 3701 to thoroughly rinse the surface of the metal sheet and completely remove residual foam, oil stains and small impurities. Through the orderly cooperation of the cleaning brush 43 and the tilting nozzle 3701, the cleaning brush 43 first rubs and peels off the stains on the surface of the metal sheet, and then the tilting nozzle 3701 sprays clean water to rinse and scrub. The cleaning process is repeated on the metal plate surface, where the detached dirt and residual foam are promptly removed, preventing stains and effectively improving the overall cleaning quality. This ensures the equipment operates continuously and stably. Meanwhile, the mixture of foam, oil, and impurities washed off the metal plate surface falls downwards along the gaps in the toothed support frame 5. Guided by the inclined inner wall of the guide frame 301, it continues to fall, passing through the rectangular groove in the top plate 3, and finally collects in the water collection tank 77 at the bottom of the outer casing 2. When the cleaning brush 43 detaches and moves away from the metal plate, the third moving plate 31 stops moving. It is worth noting that the tilting nozzle 3701 continuously sprays clean water to rinse the brushes on the cleaning brush 43 a second time, promptly removing residual impurities and foam from its surface, preventing dirt accumulation, and avoiding... Subsequent operations may cause secondary contamination of the metal sheet (at this point, the cleaning brush 43 has detached and moved away from the metal sheet, and the impurities washed off the cleaning brush 43 will not fall onto the metal sheet). At this time, the water pump 51 is turned off, and the output end of the second electric push rod 32 drives the first rectangular frame 36 and the second rectangular frame 39 to move upwards, causing the first gear 45 to move upwards and disengage from the first rack 29. Once completely disengaged from the first rack 29, the second electric push rod 32 stops moving, and the electric slide rail 30 drives the third moving plate 31 to move and reset. Then, the third electric push rod 56 is activated, and its output end drives the gantry bracket 57, the air knife 58, and the arc-shaped scraper 59 to move downwards simultaneously. It is worth noting that the working surface of the arc-shaped scraper 59 is lower than that of the air knife. On the working surface of plate 58, after the arc-shaped scraper 59 descends to the same level as the metal sheet, the third moving plate 31 moves again, and at the same time, the air knife 58 is activated. High-pressure airflow is used to blow away the surface water on the laser-cut side of the metal sheet. The arc-shaped scraper 59 moves synchronously against this side surface, adapting to the contour of the sheet using its arc-shaped structure to scrape away any residual water and water trapped in the corners that the airflow cannot remove. The two work together to thoroughly remove all water stains on the laser-cut side, ensuring the sheet surface is fully dry and effectively avoiding processing hazards caused by moisture. This provides dry and clean working conditions for subsequent laser cutting processes. Once the air knife 58 and the arc-shaped scraper 59 detach and move away from the metal sheet, the air knife 58 is turned off, and the second electric push rod 32 and the third electric push rod 56 are activated.The output end of the second electric push rod 32 drives the first rectangular frame 36 and the second rectangular frame 39 to reset, and the output end of the third electric push rod 56 drives the air knife 58 and the arc-shaped scraper 59 to move upward and reset. Subsequently, the electric slide 18 is activated, which drives the second moving plate 19, the hollow elongated shell 21, the first electric push rod 26, and the laser cutting head 27 to move along the axial direction until the laser cutting head 27 is moved to the working position above the metal sheet. After it is in position, the drive motor 22 is activated. The output shaft of the drive motor 22 drives the threaded rod 23 to rotate. The threaded rod 23 drives the third slider 24 to move laterally through the threaded transmission. The third slider 24 simultaneously drives the fixed plate frame 25, the first electric push rod 26, and the laser cutting head 27 to make slight lateral adjustments along the hollow elongated shell 21. After positioning is completed, the first electric push rod 26 and the laser cutting head 27 are activated. The output end of the first electric push rod 26 drives the laser cutting head 27 to move downward, so that the laser cutting head 27 reaches the cutting height. The laser cutting head 27 cuts the surface of the metal sheet. As the hollow elongated shell 21 moves, it simultaneously moves the fourth connecting rod 60, the fourth moving plate 61, and the fifth moving plate 62 along the limiting frame 63. The fifth moving plate 62 moves the first collecting shell 64 synchronously. The first collecting shell 64, through the limiting shell 82, drives the third rotating shaft 81 and the fourth gear 80 to mesh with the second rack 79. At this time, the laser cutting head 27 and the first collecting shell 64 are on the same vertical horizontal plane. When the laser cutting head 27 laser-cuts the metal sheet, it produces slag and scrap. Due to the uniform gaps on the toothed support frame 5, the slag and scrap, under the action of gravity, pass through the gaps in the toothed support frame 5 and fall directly downwards into the first collecting shell 64 below. While the metal sheet is being laser-cut, the vacuum fan 74 is activated. The suction end of the vacuum fan 74, through the suction head 75, creates negative pressure. This suction passes through the filter baffle 70 and acts on the first collection shell 64, causing the falling molten slag to move towards the filter baffle 70 under negative pressure and ultimately be blocked by it. Because the molten slag produced during cutting is at a high temperature, it adheres to the filter baffle 70 upon contact. The scrap material falls onto the inclined guide plate 65. Through the inclined guide plate 65, the scrap material slides along the inclined surface towards the outlet of the first collection shell 64, eventually falling into the third collection shell 76 for collection. As the laser cutting head 27 follows the guiding direction of the hollow elongated shell 21, it completes the cutting of the metal sheet. After a single-pass cutting operation in the width direction of the sheet metal, the electric carriage 18 drives the hollow elongated shell 21 and the laser cutting head 27 to move to the next cutting position of the metal sheet. At the same time, the hollow elongated shell 21 drives the first collecting shell 64 to move synchronously through the fourth connecting rod 60, the fourth moving plate 61 and the fifth moving plate 62. When the first collecting shell 64 moves, it drives the third rotating shaft 81 and the fourth gear 80 through the limiting shell 82, so that they mesh and transmit power along the second rack 79 again. When the fourth gear 80 moves and rolls along the second rack 79, it synchronously drives the third rotating shaft 81 and the fixing ring 83 to rotate. The rotation of the fixing ring 83 drives the second spring 84 and the vibrating ball 85 on it to rotate synchronously around the third rotating shaft 81. When the vibrating ball 85 rotates and collides with the bottom of the inclined guide plate 65,The inclined guide plate 65 vibrates upon impact, effectively preventing scrap from accumulating and getting stuck at the connection between the inclined guide plate 65 and the discharge port, ensuring smooth material discharge. Simultaneously with the movement of the first collection shell 64, the fourth electric push rod 68 is activated. The output end of the fourth electric push rod 68 drives the second connecting plate 69, filter baffle 70, and elastic baffle 71 downwards. When the elastic baffle 71 moves downwards and contacts the arc-shaped protrusion 72, it vibrates upon impact, causing the slag adhering to the filter baffle 70 to fall off and into the second collection shell 73. The elastic baffle 71 acts as a barrier between the filter baffle 70 and the bottom of the suction head 75, preventing... To prevent molten slag from getting stuck in the suction head 75 and clogging the suction channel, it's worth noting that the suction head 75 continuously draws in ambient air, accelerating airflow at the filter baffle 70 and speeding up slag cooling and solidification, facilitating subsequent vibration-based slag removal. After laser cutting of the metal sheet is completed, the second collection shell 73 is manually disassembled to clean the internal molten slag. Simultaneously, the scrap material in the third collection shell 76 is collected and processed. After processing, the second collection shell 73 is reset, and the liquid in the water collection tank 77 is drained through the drain valve. The electric slide 18 then drives the laser cutting head 27 and the first collection shell 64 to reset, ready for the next batch of metal sheets to be laser cut.
