Description

Technical Field

[0001] This invention relates to the field of metal plate cutting technology, specifically to a laser cutting device for processing metal backing plates. Background Technology

[0002] Metal liners, as an important industrial component, are widely used in mining machinery, engineering machinery, metallurgical equipment, power equipment, and many other fields. Their main function is to protect the core components of equipment, reduce the wear and tear on the equipment body caused by material impact and friction, and extend the service life of the equipment. As industrial production develops towards high efficiency, precision, and intelligence, the market has put forward increasingly higher requirements for the processing precision, surface quality, production efficiency, and personalized customization capabilities of metal liners. Laser cutting technology, with its advantages of high cutting precision, small heat-affected zone, fast cutting speed, and strong adaptability, is gradually being promoted and applied in the field of metal processing.

[0003] In practical operation, existing laser cutting equipment for processing metal backing plates faces challenges due to the thickness and weight of the plates. The lack of a support structure on the worktable necessitates manual handling during loading and unloading, a cumbersome and inefficient process. Furthermore, the worktable often employs a strip-shaped support structure, leading to the accumulation of molten waste on the surface and in the gaps. This accumulation not only raises the workpiece support surface but also affects the heat distribution below the laser beam. Additionally, the irregular return of the laser to the bottom of the workpiece can cause secondary burning or adhesion. Current cleaning methods for these strip support bars primarily involve manual cleaning after machine shutdown, which is extremely inefficient, interrupts continuous processing, and fails to thoroughly clean hard-to-reach areas such as gaps between the support bars, making it difficult to achieve efficient and safe cleaning of the strip support bars.

[0004] Based on this, the present invention designs a laser cutting device for processing metal backing plates to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a laser cutting device for processing metal backing plates, so as to solve the problem mentioned in the background art that the worktable lacks a structure design for assisting in picking and placing, and that manual assistance is usually required during loading and unloading, which is cumbersome and inefficient. Existing cleaning methods for strip support bars mostly involve manual cleaning after the machine is stopped, which is not only extremely inefficient, but also interrupts the continuous processing flow, and the dead corners such as the gaps between support bars are not thoroughly cleaned.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A laser cutting device for processing metal lining plates includes a laser cutting frame with a protective cover. A movable cutting frame is installed inside the laser cutting frame, and a laser cutting head is mounted on the movable cutting frame. A material support assembly is located below the laser cutting head. A fixed frame slides around the material support assembly and is fixed inside the laser cutting frame. Adjustment components are fixedly connected to both sides of the bottom of the fixed frame. The top of each adjustment component is fixed to one side of the bottom of the material support assembly. Several support components are installed within the material support assembly, located between the material support assembly and the adjustment components. Several cleaning components are fixedly installed within the support components. A smoke removal assembly is installed at the rear of the laser cutting frame. A collection assembly is installed at the lower part of the laser cutting frame, corresponding to the position of the material support assembly. A collection box is located below the collection assembly and is inserted into the bottom of the laser cutting frame.

[0008] As a further embodiment of the present invention, the material support assembly includes a cutting table, in which a plurality of strip-shaped support bars are fixed. Side plates are fixed on the front and rear sides of the bottom of the cutting table, and a plurality of sliding grooves are opened on the opposite sides of the two side plates. The sliding grooves are L-shaped structures composed of vertical grooves and inclined grooves. The two corresponding sliding grooves in the two side plates are slidably connected to the two ends of the same support assembly.

[0009] As a further embodiment of the present invention, the adjustment component includes a U-shaped plate, the two ends of the top of the U-shaped plate are fixed to one side of the bottom of the fixed frame, and an electric hydraulic rod and a track are fixedly connected to both sides inside the U-shaped plate. The top of the electric hydraulic rod is fixed to the bottom of the cutting table, and the bottoms of several support components are slidably connected to the two tracks.

[0010] As a further embodiment of the present invention, the support assembly includes a support frame located between two adjacent strip support bars. Sliding columns are fixed to both ends of the support frame and are slidably connected to grooves in the side plate. Sliding blocks are fixed to both sides of the bottom of the support frame and are slidably connected to a track. Both the sliding blocks and the track have a T-shaped cross-section. Several support wheels are installed inside the support frame, located between two adjacent strip support bars, with the top of the support wheels higher than the support frame.

[0011] As a further embodiment of the present invention, the cleaning assembly includes a slide cylinder, which is fixedly installed inside a support frame. Slide rods slide through both ends of the slide cylinder, and a support spring is fixedly connected between two slide rods. The other ends of several slide rods pass through the slide cylinder and are fixedly attached to the same scraper rod. The scraper rod is attached to the side wall of the strip support bar, and the side of the scraper rod near the strip support bar is inclined. The top of the scraper rod is inclined and faces the strip support bar.

[0012] As a further embodiment of the present invention, a protective cover is provided on the laser cutting machine frame above the laser cutting head. Electric push rods are rotatably connected to both sides of the bottom of the protective cover via pins. The bottom end of the electric push rod is rotatably connected to the opening of the laser cutting machine frame via pins. A cover plate is hinged to the rear of the laser cutting machine frame via a hinge. The smoke removal assembly is located below the cover plate.

[0013] As a further embodiment of the present invention, the smoke removal assembly includes a baffle plate, which is fixed inside the laser cutting machine frame and located behind the laser cutting head. An adsorption hood is inserted through the baffle plate, and a fan is connected to the back of the adsorption hood. A filter cartridge is connected to the air outlet of the fan, and the filter cartridge is installed in the opening at the rear of the laser cutting machine frame.

[0014] As a further embodiment of the present invention, two electric multi-stage telescopic rods are fixed on the front side of the baffle below the adsorption hood, and a push plate is fixed at the front end of the two electric multi-stage telescopic rods. The push plate is located behind the material support assembly.

[0015] As a further embodiment of the present invention, the collecting component includes a collecting hopper, which is located below the material support component and fixed inside the laser cutting machine frame. A partition is fixed to the inner wall of the collecting hopper, and the gap between the collecting hopper and the partition forms an air duct structure with the opening facing upward. An exhaust fan is installed through the back of the collecting hopper and communicates with the air duct.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention retracts the electric hydraulic rod of the adjustment component, causing the material support component to slide down the fixed frame. During the downward movement of the side plate and L-shaped chute, the sliding column in the support component slides within the inclined section of the L-shaped chute, simultaneously pushing the support frame upward and to the left. The T-shaped track limits the bottom slider of the support frame, improving the stability of the support component's movement. When the sliding column reaches the vertical section of the L-shaped chute, the support frame, support wheel, and cleaning component are positioned between two adjacent strip support bars. As the sliding column slides along the chute's vertical section, the support frame drives the cleaning component and support wheel to move vertically upward. During this process, the two scrapers in the cleaning component can engage with the opposing surfaces of the two adjacent strip support bars. The scrapers, through the sliding cooperation between the sliding rod and the sliding cylinder, are supported by the elastic force of the support spring. Closely fitted to the sidewall of the strip support bar, any waste residue from cutting that adheres to the sidewall of the strip support bar will be scraped off in real time by the scraper. The scraper is inclined on the side and top of the strip support bar, making it easy for waste residue to slide down the inclined surface. Similarly, when scraping and cleaning the strip support bar in the opposite direction, the electric hydraulic rod extends, driving the material support assembly to move upward as a whole within the fixed frame. The scraper in the support assembly will then slide down between two adjacent strip support bars to clean their surfaces until the support assembly is located directly below the strip support bar. The strip support bar, as the main support structure, is exposed, and the support wheels on the support assembly are lower than the top surface of the strip support bar to avoid interfering with the placement of the liner. This eliminates the need for traditional manual cleaning after machine shutdown, enabling simultaneous cleaning of all strip support bars and achieving efficient and safe cleaning of the strip support bars. 2. In this invention, after the material support assembly is lowered, the strip support bar in the material support assembly moves down synchronously. When the sliding column in the support frame slides to the highest point of the vertical section of the L-shaped chute, the top of the support wheel in the support frame is higher than the strip support bar. With the help of the rolling characteristics of the support wheel, the cut metal liner can be easily removed from the cutting table. When batch unloading is required, or when the finished liner is too large or too heavy to be manually removed, the electric multi-stage telescopic rod is activated to extend and push the push plate forward. The push plate acts on the rear edge of the finished liner, pushing the liner forward to a position that is easy for the operator to grab, improving the convenience of material unloading and reducing the workload. 3. This invention utilizes the laser cutting process to generate smoke that diffuses into the surrounding area. A fan creates negative pressure in the adsorption hood, rapidly drawing the smoke from behind the cutting area into the hood. The smoke then enters a filter cartridge for filtration and purification. The purified gas is discharged outside the device, preventing smoke from harming the operator's health and optimizing the processing environment. The rear cover of the laser cutting machine frame can also be opened for regular cleaning of the filter cartridge. Simultaneously, the exhaust fan in the collection assembly activates, creating an upward airflow through the duct structure formed by the collection hopper and partition, further enhancing the collection of smoke and fine dust. This achieves initial separation of dust from large pieces of waste residue and quickly removes heat from the device. Molten waste residue generated during cutting falls downwards under gravity and enters the collection hopper, where it is finally collected. When the waste residue accumulates to a certain amount in the collection box, the operator can directly remove the collection box, which is inserted into the bottom of the laser cutting machine frame, for centralized waste residue treatment.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-11 The present invention provides a technical solution:

[0022] A laser cutting device for processing metal lining plates includes a laser cutting frame 1, a protective cover 2 installed on the laser cutting frame 1, a movable cutting frame 3 installed inside the laser cutting frame 1, a laser cutting head 4 installed on the movable cutting frame 3, and a material support assembly 5 provided below the laser cutting head 4. The movable cutting frame 3 is composed of a transverse moving frame and a longitudinal moving frame. Two longitudinal guide rails are fixed in parallel on the top of the inner walls on both sides of the laser cutting frame and connected to the longitudinal moving frame. The transverse moving frame is installed on the two longitudinal guide rails, and the longitudinal moving frame is provided with a longitudinal guide rail. The longitudinal guide rails are slidably installed with the laser cutting head 4, so that the laser cutting head 4 can realize transverse and longitudinal cutting functions.

[0023] The existing structure corresponding to the movable cutting frame 3 is a mature mobile gantry frame in the field of laser cutting, which can achieve the purpose of automatic position adjustment.

[0024] Specifically, the material support assembly 5 includes a cutting table 501, in which several strip-shaped support bars 502 are fixed. Side plates 503 are fixed to the front and rear sides of the bottom of the cutting table 501. Several sliding grooves 504 are correspondingly formed on opposite sides of the two side plates 503. Each sliding groove 504 is an L-shaped structure composed of vertical and inclined grooves. The two corresponding sliding grooves 504 on the two side plates 503 are slidably connected to the two ends of the same support assembly 8. The strip-shaped support bars 502 serve as the main support structure, providing uniform support to the metal liner and preventing deformation due to uneven local stress, thus ensuring laser cutting accuracy. Simultaneously, their gaps allow molten waste generated during cutting to fall smoothly, facilitating subsequent waste collection.

[0025] As a further embodiment of the present invention, a fixed frame 6 is slidably attached to the outside of the material support component 5. Specifically, the outside of the material support component 5 slides through the opening provided in the middle of the fixed frame (6). The fixed frame 6 is fixed inside the laser cutting machine frame 1. Adjustment components 7 are fixedly connected to both sides of the bottom of the fixed frame 6. The top of the adjustment component 7 is fixed to one side of the bottom of the material support component 5. Several support components 8 are installed in the material support component 5. The support components 8 are located between the material support component 5 and the adjustment components 7.

[0026] Specifically, the adjustment component 7 includes a U-shaped plate 701, the two ends of the top of the U-shaped plate 701 are fixed to one side of the bottom of the fixed frame 6, and the two sides inside the U-shaped plate 701 are fixedly connected to an electric hydraulic rod 702 and a track 703. The top of the electric hydraulic rod 702 is fixed to the bottom of the cutting table 501. The bottom of several support components 8 are slidably connected to two tracks 703. The support components 8 include a support frame 801, which is located between two adjacent strip support bars 502. The two ends of the support frame 801 are respectively fixed with sliding columns 802, which are slidably connected to the sliding grooves 504 in the side plate 503.

[0027] When the electric hydraulic rod 702 in the adjusting component 7 extends, it drives the material support component 5 to move upward as a whole within the fixed frame 6, and the side plate 503 and the slide groove 504 move upward simultaneously. At this time, the sliding columns 802 at both ends of the support component 8 slide vertically along the L-shaped slide groove 504 on the side plate 503. When the sliding column 802 slides to the inclined section of the L-shaped slide groove 504, the support component 8 is located below the strip support bar 502 in the material support component 5. When the side plate 503 and the slide groove 504 continue to move upward, the sliding column 802 slides in the inclined section of the L-shaped slide groove 504. During this process, the slide groove 504 pushes the support frame 801 in the support component 8 to slide downward to the right through the sliding column 802 until the support component 8 is located directly below the strip support bar 502. Therefore, the support component 8 will not interfere with the cutting path during the cutting operation, and it can also prevent residue from splashing onto the support component 8.

[0028] As a further embodiment of the present invention, sliders 803 are fixed on both sides of the bottom of the support frame 801, and the sliders 803 are slidably connected in the track 703. The cross-sectional shape of both the sliders 803 and the track 703 is T-shaped. Several support wheels 804 are installed inside the support frame 801. The support wheels 804 are located between two adjacent strip support bars 502, and the top of the support wheels 804 is higher than the support frame 801.

[0029] During operation, the T-shaped track 703 limits the bottom slider 803 of the support frame 801, improving the stability of the movement of the support assembly 8. When the sliding column 802 slides to the highest point of the vertical section of the L-shaped slide groove 504, the top of the support wheel 804 in the support frame 801 is higher than the strip support bar 502. With the help of the rolling characteristics of the support wheel 804, the cut metal liner can be easily removed from the cutting table 501, improving the ease of operation.

[0030] As a further embodiment of the present invention, a plurality of cleaning components 9 are fixedly installed in the support assembly 8. The cleaning component 9 includes a slide cylinder 901, which is fixedly inserted into the support frame 801. Slide rods 902 slide through both ends of the slide cylinder 901. A support spring 903 is fixedly connected between two slide rods 902. The other ends of the plurality of slide rods 902 pass through the slide cylinder 901 and are fixedly attached to the same scraper 904. The scraper 904 is attached to the side wall of the strip support bar 502. The side of the scraper 904 near the strip support bar 502 is inclined, and the top of the scraper 904 is inclined and faces the strip support bar 502.

[0031] The two scraper rods 904 in the cleaning component 9 can fit against the opposite surfaces of two adjacent strip support bars 502. The scraper rods 904 are in close contact with the side wall of the strip support bar 502 under the elastic force of the support spring 903 through the sliding cooperation of the slide bar 902 and the slide cylinder 901. If the waste generated by cutting is attached to the side wall of the strip support bar 502, it will be scraped off by the scraper rods 904 in real time. The scraper rods 904 are inclined on the side and top of the strip support bar 502 to facilitate the waste to slide down the inclined surface.

[0032] As a further embodiment of the present invention, a protective cover 10 is provided on the laser cutting frame 1 above the laser cutting head 4. Electric push rods 11 are rotatably connected to the bottom sides of the protective cover 10 via pins. The bottom ends of the electric push rods 11 are rotatably connected to the opening of the laser cutting frame 1 via pins. A cover plate 12 is hinged to the rear of the laser cutting frame 1 via a hinge. The smoke removal assembly 13 is located below the cover plate 12.

[0033] The liner is placed on the strip support bar 502 in the material support assembly 5. The protective cover 10 is retracted by the electric push rod 11 to flip and close, forming a closed processing space with the protective cover 2 on the laser cutting machine frame 1, preventing the spread of metal dust and smoke during the cutting process.

[0034] As a further embodiment of the present invention, a smoke removal assembly 13 is installed at the rear position inside the laser cutting machine frame 1. The smoke removal assembly 13 includes a baffle 131, which is fixed inside the laser cutting machine frame 1 and located behind the laser cutting head 4. An adsorption cover 132 is inserted through the baffle 131. A fan 133 is connected to the back of the adsorption cover 132. A filter cartridge 134 is connected to the air outlet of the fan 133. The filter cartridge 134 is installed in the rear opening of the laser cutting machine frame 1.

[0035] The operation of the blower 133 creates a negative pressure in the adsorption hood 132, which quickly adsorbs the smoke behind the cutting area into the adsorption hood 132. The smoke then enters the filter cartridge 134 for filtration and purification. The purified gas is discharged outside the device, avoiding the smoke from harming the health of the operators and optimizing the processing environment.

[0036] As a further embodiment of the present invention, two electric multi-stage telescopic rods 14 are fixed on the front side of the baffle 131 below the adsorption cover 132, and a push plate 15 is fixed at the front end of the two electric multi-stage telescopic rods 14. The push plate 15 is located behind the material support assembly 5.

[0037] When batch unloading is required, or when the finished liner is too large or too heavy to be manually removed, the electric multi-stage telescopic rod 14 is activated to extend and push the push plate 15 forward. The push plate 15 acts on the rear edge of the finished liner, pushing the liner forward to a position that is easy for the operator to grab, thus improving the convenience of unloading. After the push is completed, the electric multi-stage telescopic rod 14 retracts and drives the push plate 15 to reset.

[0038] As a further embodiment of the present invention, a collection component 16 is installed at the lower part of the laser cutting frame 1, corresponding to the position of the material support component 5. A collection box 17 is provided below the collection component 16 and is inserted into the bottom of the laser cutting frame 1.

[0039] Specifically, the collection component 16 includes a collection hopper 161, which is located below the material support component 5 and fixed inside the laser cutting frame 1. The molten waste generated during the cutting process falls downward under the action of gravity and enters the collection hopper 161, and is finally collected by the collection box 17. When the waste in the collection box 17 accumulates to a certain amount, the operator can directly pull out the collection box 17 inserted at the bottom of the laser cutting frame 1 for centralized waste treatment. After the treatment is completed, the collection box 17 is reinserted at the bottom of the laser cutting frame 1.

[0040] A partition 162 is fixed to the inner wall of the collection hopper 161. The gap between the collection hopper 161 and the partition 162 forms an air duct structure with the opening facing upward. An exhaust fan 163 is installed through the back of the collection hopper 161 and is connected to the air duct.

[0041] During operation, the exhaust fan 163 is activated, causing the air duct structure formed by the collection hopper 161 and the baffle 162 to generate an upward airflow, which helps to improve the collection effect of smoke and fine dust, achieves the initial separation of dust and large pieces of waste residue, and can quickly remove the heat inside the device.

[0042] Working principle of this invention:

[0043] Before starting the device, the electric hydraulic rod 702 in the adjusting component 7 extends, causing the material support component 5 to move upward as a whole within the fixed frame 6. Simultaneously, the side plate 503 and the slide groove 504 move upward. At this time, the sliding columns 802 at both ends of the support component 8 slide vertically along the L-shaped slide groove 504 on the side plate 503. When the sliding column 802 slides to the inclined section of the L-shaped slide groove 504, the support component 8 is positioned below the strip support bar 502 in the material support component 5. As the side plate 503 and the slide groove 504 continue to move upward, the sliding column 802 moves along the inclined section of the L-shaped slide groove 504. During the sliding process, the slide groove 504 pushes the support frame 801 in the support assembly 8 to slide to the lower right through the slide column 802 until the support assembly 8 is located directly below the strip support bar 502. At the same time, the slider 803 at the bottom of the support assembly 8 slides smoothly along the track 703 of the adjustment assembly 7, improving the stability of the movement of the support assembly 8. In this state, the strip support bar 502, as the main support structure, is exposed, and the support wheel 804 on the support assembly 8 is lower than the top surface of the strip support bar 502 to avoid interference with the placement of the liner.

[0044] Next, the liner is placed on the strip support 502 in the material support assembly 5. The protective cover 10 is retracted and flipped closed by the electric push rod 11, forming a closed processing space with the protective cover 2 on the laser cutting frame 1 to prevent the spread of metal dust and smoke during the cutting process. Then, according to the size, material and cutting requirements of the liner to be processed, the cutting parameters are preset, and the movable cutting frame 3 is controlled to drive the laser cutting head 4 to move and position in multiple directions inside the laser cutting frame 1. After the laser cutting head 4 is started, it emits a high-energy-density laser beam that acts on the surface of the metal liner, making... The material in the liner cutting area melts and vaporizes rapidly. At the same time, the molten waste generated during the cutting process falls downward under the action of gravity and enters the collection hopper 161. Finally, it is collected by the collection box 17. When the waste in the collection box 17 accumulates to a certain amount, the operator can directly pull out the collection box 17 inserted into the bottom of the laser cutting machine frame 1 for centralized waste treatment. After the treatment is completed, the collection box 17 is reinserted into the bottom of the laser cutting machine frame 1 to complete the cycle. Some waste adheres to the side of the strip support bar 502, and the smoke generated by cutting spreads to the surroundings.

[0045] When the smoke generated by laser cutting spreads, the smoke removal component 13 is activated, and the fan 133 runs to create negative pressure in the adsorption hood 132, which quickly adsorbs the smoke behind the cutting area into the adsorption hood 132. Then the smoke enters the filter cartridge 134 for filtration and purification. The purified gas is discharged outside the device to avoid smoke from harming the health of operators and to optimize the processing environment. The rear cover plate 12 of the laser cutting machine frame 1 can also be opened to clean the filter cartridge 134 regularly. At the same time, the exhaust fan 163 in the collection component 16 is activated, which generates an upward airflow in the air duct structure formed by the collection hopper 161 and the partition plate 162, which helps to improve the collection effect of smoke and fine dust, achieves the initial separation of dust and large waste residue, and can quickly remove the heat inside the device.

[0046] After the cutting work is completed, the electric push rod 11 extends to open the protective cover 10. Next, the electric hydraulic rod 702 of the adjusting component 7 retracts, causing the material support component 5 to slide down in the fixed frame 6. During the downward movement of the side plate 503 and the L-shaped chute 504, the sliding column 802 in the support component 8 can slide in the inclined section of the L-shaped chute 504, simultaneously pushing the support frame 801 to the upper left. The T-shaped track 703 limits the bottom slider 803 of the support frame 801, improving the stability of the support component 8's movement. When the sliding column 802 slides to the vertical section of the L-shaped chute 504, the support frame 801, support wheel 804, and cleaning component 9 are located between two adjacent strip support bars 502. The sliding column 802 is in the chute 504... During the sliding process of the 4-segment, the support frame 801 drives the cleaning component 9 and the support wheel 804 to move vertically upward. During this process, the two scrapers 904 in the cleaning component 9 can fit against the opposite surfaces of the two adjacent strip support bars 502. The scrapers 904 are tightly fitted against the side wall of the strip support bar 502 under the elastic force of the support spring 903 through the sliding cooperation of the slide bar 902 and the slide cylinder 901. If the waste residue generated by cutting is attached to the side wall of the strip support bar 502, it will be scraped off by the scrapers 904 in real time. The scraper 904 is inclined on the side and top of the strip support bar 502, which makes it easy for the waste residue to slide down along the inclined surface. At the same time, it plays a guiding role for the scrapers 904, so that the scrapers 904 will not be interfered with by the path when moving vertically.

[0047] When the sliding column 802 slides to the highest point of the vertical section of the L-shaped chute 504, the top of the support wheel 804 in the support frame 801 is higher than the strip support bar 502. With the help of the rolling characteristics of the support wheel 804, the cut metal liner can be easily removed from the cutting table 501. When batch unloading is required, or when the finished liner is too large or too heavy to be manually removed, the electric multi-stage telescopic rod 14 is activated to extend and push the push plate 15 forward. The push plate 15 acts on the rear edge of the finished liner, pushing the liner forward to a position that is easy for the operator to grab, improving the convenience of unloading. After pushing is completed, the electric multi-stage telescopic rod 14 retracts and drives the push plate 15 to reset, avoiding interference with subsequent processing.
