Description

Technical Field

[0001] This invention relates to the manufacture of metal cutting equipment, and more particularly to the field of sheet metal processing technology, specifically a sheet metal cutting and processing device. Background Technology

[0002] Sheet metal cutting is a core process in metal processing. It involves using methods such as laser cutting, plasma cutting, and mechanical cutting to process metal sheets into predetermined dimensions and shapes, and is widely used in industries such as machinery manufacturing, construction, and aerospace. Among these, laser cutting has become the mainstream method for processing mid-to-high-end metal sheets due to its advantages such as high precision, high efficiency, and small heat-affected zone.

[0003] Existing laser cutting equipment typically includes a worktable, a moving mechanism, a laser cutting head, and a support mechanism. The support mechanism often uses a fixed sword-grid structure to support the cutting material, and some equipment is equipped with simple cleaning components to assist in cleaning up the slag and waste generated during cutting. However, existing technology has significant shortcomings: 1. When laser cutting high-reflectivity metal sheets, the reflected beam is prone to back-echoing into the laser cutting head, causing aging and damage to core components and shortening the service life of the equipment. Existing simple light-shielding structures cannot achieve efficient isolation. Second, during the material feeding and adjustment stage, the tip of the sword grid is prone to scratching the surface of the sheet material, affecting the appearance quality of the workpiece; during the cutting process, molten slag is prone to stick to the surface and gaps of the sword grid support strip, and long-term accumulation leads to uneven support surface and reduces cutting accuracy.

Detailed Implementation

[0019] 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.

[0020] Example 1: Please refer to Figures 1 to 11 In this embodiment of the invention, a metal sheet cutting and processing device includes a worktable 1, with support legs 2 fixedly installed on the bottom surface of the worktable 1 near the corners; it also includes: The laser cutting mechanism 4 has an isolation component at its front end to isolate and shield laser reflections in order to reduce the damage to the equipment. The moving mechanism 3, which is fixedly installed on the worktable 1, is used to control the three-dimensional movement of the laser cutting mechanism 4; A self-cleaning support mechanism 5 is fixedly installed on the workbench 1. The self-cleaning support mechanism 5 includes: A fixed support assembly installed on the workbench 1 is used to support the plate during the feeding and adjustment process; A lifting support assembly is installed on the workbench 1; it is used to support the plate during the cutting process and to cooperate with the fixed support assembly to achieve initial self-cleaning. And a cleaning component fixedly installed on the workbench 1, used in conjunction with the lifting support component for further cleaning.

[0021] This embodiment constructs a complete metal sheet cutting system through the coordinated operation of the worktable 1, laser cutting mechanism 4, moving mechanism 3, and self-cleaning support mechanism 5. During operation, the moving mechanism 3 drives the laser cutting mechanism 4 to achieve three-dimensional movement, precisely covering the cutting area; the fixed support component and the lifting support component of the self-cleaning support mechanism 5 work alternately to meet different needs for material loading adjustment and cutting support; the cleaning component specifically cleans residual slag from the sword grid support strip 18. The isolation component of the laser cutting mechanism 4 synchronously isolates reflected laser light to prevent equipment damage.

[0022] This invention achieves integrated "support-cutting-isolation-cleaning" operations through modular division of labor and collaborative work, significantly improving the continuity and stability of processing.

[0023] Example 2: Please refer to Figures 1 to 8 Based on Embodiment 1, the fixed support assembly includes a support platform 17 set directly above the workbench 1. Frames 16 are fixedly installed on both sides of the support platform 17, and support rods 15 are fixedly connected between the bottom ends of the frame 16 and the top surface of the workbench 1. The top surface of the support platform 17 has multiple clearance slots 23 that are parallel to the width direction of the support platform 17, and the multiple clearance slots 23 are arranged in an array along the length direction of the frame 16.

[0024] The lifting support assembly includes a cylinder 20 fixedly installed at the center of the bottom surface of the workbench 1 and a lifting platform 21 set between the support platform 17 and the workbench 1. Telescopic rods 19 are fixedly installed between the bottom surface of the lifting platform 21 and the top surface of the workbench 1 near the corner. The telescopic end of cylinder 20 slides through the worktable 1 to the top of the worktable 1 and is then fixedly connected to the bottom surface of the lifting platform 21. On both sides of the top surface of the lifting platform 21, there are multiple mounting seats 22 arranged in an array along its length direction, which are equal in number to the number of clearance slots 23 and aligned one by one. Between the tops of two opposite mounting seats 22, a sword-grid support bar 18 that works with the clearance slot 23 is detachably fixed.

[0025] During the material loading and adjustment phase, the control cylinder 20 retracts, causing the lifting platform 21 to descend. The sword grid support bar 18 moves with the lifting platform 21 to below the support platform 17, at which point the top of the support platform 17 provides smooth support to the sheet material. This design avoids direct contact between the tip of the sword grid support bar 18 and the sheet material, solving the problem of the sheet material being easily scratched during material loading and adjustment on existing equipment, and ensuring the integrity of the sheet material surface.

[0026] Once the plate position is determined, the control cylinder 20 extends, causing the lifting platform 21 to rise. The telescopic rod 19 extends and retracts synchronously to ensure the smooth movement of the lifting platform 21. The sword grid support bar 18 extends above the support platform 17 through the clearance groove 23, providing precise support for the plate. The array distribution of the sword grid support bar 18 ensures support stability and provides a falling channel for cutting waste and slag, preventing waste accumulation from affecting the cutting effect. Compared with the existing fixed sword grid support, its adaptability and practicality are significantly improved.

[0027] Example 3: Please refer to Figures 1-6 Based on embodiment 1, the cleaning component includes a second mounting base 32 and a slide 24 disposed between the lifting platform 21 and the frame 16. The slide 24 has slide rods 31 slidably mounted through it on the wide side near both ends. The two ends of the slide rods 31 are fixedly mounted with a third fixing base 30 between them and the top surface of the workbench 1. Mounting base 2 32 is fixedly installed at the middle position of one end of the top surface of the workbench 1. Motor 2 33 is fixedly installed on the outside of mounting base 2 32. The output shaft of motor 2 33 rotates through mounting base 2 32 and is fixedly connected to screw 34. The top surface of the slide table 24 is fixedly installed with an internal threaded sleeve 35 at the end near the motor 2 33, and the end of the screw 34 away from the motor 2 33 is threadedly installed in the internal threaded sleeve 35; A vibratory scraping assembly is fixedly installed on the top surface of the slide table 24.

[0028] After cutting, the control cylinder 20 retracts, causing the lifting platform 21 to descend. The sword grid support bar 18 and the clearance groove 23 move relative to each other. The clearance groove 23 scrapes away the molten slag adhering to the side of the sword grid support bar 18, completing the initial self-cleaning process. This process requires no additional power; cleaning is achieved synchronously through the lifting motion of the support components, improving operational efficiency.

[0029] After initial cleaning, start motor 23 to drive screw 34 to rotate, and drive slide 24 to reciprocate along slide rod 21 through internal thread sleeve 35. The vibrating scraping component on the top surface of slide 24 moves with slide 24 to thoroughly scrape and clean the sword grid support bar 18.

[0030] Example 4: Please refer to Figures 1-6Based on embodiment 3, the vibratory scraping assembly includes mounting base 37 and fixed base 25. Fixed base 25 is fixedly installed at the ends of both sides of the top surface of the slide table 24. A slide rod 27 is fixedly connected between the two fixed bases 25 on the same side. A slide bar 26 is slidably installed through the periphery of the slide rod 27. A connecting bar 36 is fixedly connected between one end of the two slide bars 26. Multiple inverted U-shaped seats 28 are fixedly connected between the top surfaces of the two slide bars 26. The multiple U-shaped seats 28 are arranged in an array along the length direction of the slide bar 26. The number of multiple U-shaped seats 28 is equal to the number of multiple sword grid support bars 18 and they correspond one to one. The inner top surface of the U-shaped seat 28 is provided with a cleaning rack 29 that works in conjunction with the sword grid support bar 18. Mounting base 37 is fixedly installed at the middle position of one end of slide table 24 near connecting bar 36. Reciprocating vibration motor 38 is fixedly installed on the outside of mounting base 37. The output end of reciprocating vibration motor 38 slides through mounting base 37 and is fixedly connected to connecting bar 36.

[0031] During the movement of the slide table 24, the reciprocating vibration motor 38 is activated. The reciprocating vibration motor 38 drives the slide bar 26 to reciprocate at high frequency along the slide rod 27 via the connecting bar 36. The U-shaped seat 28 on the top surface of the slide bar 26 vibrates synchronously, and the cleaning toothed rack 29 inside the U-shaped seat 28 fits against the toothed gaps of the sword grid support bar 18 in a high-frequency vibration state. The high-frequency vibration can break the adhesion between the slag and the sword grid support bar 18. Combined with the slow movement of the slide table 24, a dual cleaning effect of "vibration peeling and scraping cleaning" is achieved.

[0032] This design solves the problem that single scraping cleaning is difficult to remove stubborn slag, improving cleaning efficiency; and the vibration contact between the cleaning rack 29 and the sword grid support strip 18 avoids deformation damage to the sword grid support strip 18 caused by excessive rigid scraping force, thus extending the service life of the sword grid support strip 18.

[0033] Example 5: Please refer to Figures 9-11 Based on embodiment 1, the laser cutting mechanism 4 includes a laser cutting head 45. A connecting ring 51 for connecting an isolation component is fixedly installed on the periphery of the laser cutting head 45 near the front end. The isolation component is detachably fixed to the connecting ring 51 by bolts. The tail of the laser cutting head 45 is provided with a connecting seat for fixed connection with the moving mechanism.

[0034] The isolation assembly includes an outer isolation cover 47, which is a truncated cone that is narrow at the top and wide at the bottom, and the bottom of the outer isolation cover 47 is an open structure. The top surface of the outer isolation cover 47 is fixedly connected to the laser cutting head 45 by bolts and connecting ring 51. An inner isolation cover 48, coaxial with the outer isolation cover 47, is fixedly installed on the inner top surface of the outer isolation cover 47; An annular air guide pipe 49 is fixedly installed at the bottom of the outer isolation cover 47. An annular air outlet groove 50 aligned with the inside of the outer isolation cover 47 is opened on the periphery of the annular air guide pipe 49. An air guide pipe 46 is fixedly connected through the annular air guide pipe 49. The end of the air guide pipe 46 away from the annular air guide pipe 49 is connected to an external inert gas supply device.

[0035] During laser cutting, the isolation components work synchronously: the external inert gas supply device delivers inert gas to the annular gas guide pipe 49 through the gas guide pipe 46. The gas enters the cavity between the inner isolation cover 48 and the outer isolation cover 47 evenly through the annular gas outlet groove 50, continuously filling and discharging the air in the cavity, forming an inert gas protective environment, avoiding oxidation of the metal sheet in the cutting area, solving the problem of easy oxidation layer generation in existing equipment cutting, and improving the quality of the cut.

[0036] Meanwhile, the inner isolation shield 48 and the outer isolation shield 47 form a double-layered frustum structure, which, together with the bottom annular air curtain, constructs a dual reflection protection system of physical isolation and gas shielding. The hemispherical reflected laser beam is first blocked and absorbed by the inner isolation shield 48, and a small amount of scattered reflected light is intercepted by the outer isolation shield 47. The annular air curtain further refracts the escaped reflected light, completely preventing the reflected light from reflecting back to the laser cutting head 45, and significantly extending the service life of the laser cutting head 45.

[0037] Example 6: Please refer to Figure 1 and Figure 10 Based on embodiment 1, the moving mechanism 3 includes a boss 6. Bosses 6 are fixedly installed at the end positions on both sides of the worktable 1. A column 7 is fixedly installed on the top surface of the boss 6.

A lifting assembly for installing the laser cutting mechanism 4 is fixedly installed on the transverse moving assembly.

[0038] The transverse component includes two fixed seats 11, which are respectively fixedly installed at both ends of the side of the mounting plate 10. A guide rod 12 is fixedly installed between the two fixed seats 11, and a lead screw 13 is rotatably installed thereon. A slide block 39 is slidably installed through the guide rod 12, and the slide block 39 and the lead screw 13 are connected through the thread. A motor 14 is fixedly installed on the outside of one of the fixed seats 11. The end of the lead screw 13 near the motor 14 is rotatably inserted through the fixed seat 11 and fixedly connected to the output shaft end of the motor 14.

[0039] The lifting assembly includes a second mounting plate 40 that is vertically fixedly installed on the outside of the slide block 39. Extension plates 44 are fixedly installed on the top and bottom sides of the second mounting plate 40. Two guide rods 42 are fixedly connected between the two extension plates 44. A lifting seat 41 for fixing the laser cutting mechanism 4 is slidably installed through the periphery of the two guide rods 42. An electric telescopic rod 43 is fixedly installed on the top surface of the upper extension plate 44. The telescopic end of the electric telescopic rod 43 slides through the extension plate 44 and is fixedly connected to the top surface of the lifting seat 41.

[0040] During longitudinal movement, the rodless cylinder 9 drives the mounting plate 10 to move along the column 7 via the connecting seat 8, thereby adjusting the longitudinal position of the laser cutting mechanism 4. During lateral movement, the motor 14 drives the lead screw 13 to rotate in both directions, driving the slide 39 to slide laterally along the guide rod 12, thereby precisely adjusting the lateral position of the laser cutting mechanism 4. During lifting adjustment, the electric telescopic rod 43 extends and retracts, driving the lifting seat 41 to rise and fall along the guide rod 42, thereby achieving fine-tuning of the height of the laser cutting head 45.
