Description

Technical Field

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

[0002] Laser cutting is a high-precision, high-speed thermal cutting method. It utilizes a high-energy-density laser beam to irradiate the surface of a workpiece, causing the irradiated material to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thus cutting the workpiece. The requirements for steel cutting are highly diverse; different steel types and thicknesses require laser cutting equipment that can be flexibly adjusted to meet various process demands.

[0003] Existing cutting equipment generates metal shavings during cutting. These shavings easily enter the dust collection pipe through the dust hood with the exhaust gas, shortening the lifespan of the air pump. Simultaneously, the bottom of the workpiece easily fuses and adheres to the base: during laser cutting, a large amount of molten slag is generated at the bottom of the workpiece. This molten slag solidifies between the bottom of the workpiece and the base, forming a fused adhesion, making it difficult to remove the workpiece after cutting. This also affects the accuracy of subsequent processing and increases the workload of manual cleaning. Therefore, it does not meet the existing requirements. To address this, we propose a laser cutting device for steel processing. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention utilizes a honeycomb plate ejector structure on a base, with conical metal ejectors evenly distributed at the hexagonal skeleton nodes of the honeycomb plate. The ejector tips are higher than the upper surface of the honeycomb plate, which reduces the contact area with the steel to be cut, avoids burn marks caused by laser reflection, and ensures the steel is supported flat, preventing deformation during cutting. The inclined surface inside the honeycomb plate and the high-temperature wear-resistant coating on the surface effectively resist the high-temperature erosion of the cutting slag, extending the service life of the honeycomb plate ejector structure. It also assists in the sliding of slag, reducing accumulation. Furthermore, the bottom surface of the inclined groove inside the base is set as an inclined surface, which, together with the through groove and connecting groove below the honeycomb plate, allows the slag generated during cutting to slide smoothly into the inclined groove and be discharged through the chip removal groove connected to the inclined groove. This invention improves the cutting quality and facilitates the collection and discharge of the slag generated during cutting by setting a honeycomb plate ejector structure.

[0018] 2. This invention features symmetrical dust collection mechanisms on both sides of the laser head, which capture the dust generated during cutting. The dust is then transported to the filter box via a conveying pipe consisting of a fixed pipe and a retractable flexible hose. The filter effectively intercepts fine dust particles from the dust. Furthermore, a vibration chip removal mechanism, driven by a rotating motor, rotates a cam, causing a moving plate, insert rod, and movable plate to reciprocate. This allows a hammer to periodically strike the filter, preventing clogging and ensuring efficient dust filtration. This continuous dust capture and filtration reduces the impact of dust on the working environment and operators. The dust collection housing is threaded to the cover plate, and the filter mechanism is magnetically connected, facilitating disassembly and maintenance. The filter mechanism also prevents damage to the air pump and facilitates easy cleaning of the filter. Attached Figure Description

[0032] The ejector pin 202 is a conical metal ejector pin. The tip of the ejector pin 202 is higher than the upper surface of the honeycomb plate 201. The ejector pins 202 are evenly distributed at the hexagonal skeleton nodes of the honeycomb plate 201, which can reduce the contact area with the steel to be cut, avoid laser reflection and burn marks, and at the same time ensure that the steel is supported flat and prevent the steel from deforming during the cutting process.

[0033] The dust collection mechanism 19 includes a cover plate 1901, a grid groove 1902 and a dust collection shell 1903. The dust collection shell 1903 is connected to the cover plate 1901 by threads, and a high-temperature resistant metal grid is provided in the grid groove 1902.

[0034] The vibration chip removal mechanism 14 includes a rotating shaft 1402 and a fixed plate 1405. A cam 1401 is fitted on the outer surface of the rotating shaft 1402. A rotating motor 1403 for rotating the rotating shaft 1402 is installed on the inner wall of the filter box 11. A through hole 1408 is opened on the outer surface of the fixed plate 1405. A rod 1410 slides through the inner side of the through hole 1408. A spring 1407 is fitted on the outer surface of the rod 1410. When the rotating motor 1403 rotates, it can drive the rotating shaft 1402 to rotate, thereby driving the cam 1401 to rotate around the rotating shaft 1402.

[0035] A movable plate 1404 is fixedly installed at one end of the insertion rod 1410. The outer surface of the movable plate 1404 is symmetrically provided with an arc surface 1409 on the side near the cam 1401. A movable plate 1406 is installed at the other end of the insertion rod 1410. Multiple hammers 1411 are installed on the side of the movable plate 1406 near the filter mechanism 13. The hammers 1411 drive the movable plate 1404, the insertion rod 1410 and the movable plate 1406 to reciprocate, so that the hammers 1411 periodically strike the filter screen 1302, so as to avoid the filter screen 1302 from clogging, ensure the dust filtration efficiency, and by providing the arc surface 1409, it can prevent the cam 1401 from contacting the sharp corner of the movable plate 1404 when it rotates, prevent jamming or wear, ensure the smooth rotation of the cam 1401, and thus ensure the stable operation of the vibration chip removal mechanism 14.

[0036] The lower end face of the filter box 11 is provided with a square groove, and a single door is hinged to the inner side of the square groove. The filter mechanism 13 includes a frame 1301, a filter screen 1302 is installed on the inner wall of the frame 1301, a card plate is installed on the lower end face of the frame 1301, and a card slot is provided on the inner wall of the filter box 11. The card plate and the card slot are magnetically connected, and the filter mechanism 13 can be quickly disassembled and assembled through the strip opening 22. The single door at the lower end of the filter box 11 also facilitates the cleaning of the intercepted dust, further improving the convenience of maintenance.

[0037] The dust collection mechanism 19 is connected to the filter box 11 through the conveying pipe 9. The conveying pipe 9 includes a fixed pipe 901 and a retractable hose 902. The bottom surface of the inclined groove 17 is inclined. The front end of the base 1 is provided with a chip removal groove 18, which is connected to the inclined groove 17. The inner side of the chip removal groove 18 is hinged with a partition by a torsion spring. The partition can prevent dust leakage. The retractable hose 902 can be adapted to the omnidirectional movement of the moving base 6 and the laser head 7 to ensure the continuity of dust capture, while reducing pipe pulling losses and extending pipe service life. The partition can effectively block the high-temperature molten slag from splashing during the cutting process. When cleaning the molten slag, the partition can be manually opened to quickly remove the molten slag. After cleaning, the partition automatically resets under the elastic force of the torsion spring without additional fixing. It is convenient to operate and can continuously provide protection.

[0038] A pressing mechanism 3 is installed on both sides of the upper surface of the base 1. The pressing mechanism 3 includes an L-shaped plate 302. A pressure plate 303 is installed below the L-shaped plate 302 via a first electric push rod 301. A groove 20 is provided on the surface of the base 1. A side limiting mechanism 21 is installed inside the groove 20. The side limiting mechanism 21 includes a second electric push rod 2101. A side clamping plate 2102 is fixedly connected to the end of the second electric push rod 2101. The pressing mechanism 3 can press the upper surface of the steel and the side limiting mechanism 21 can limit the two sides of the outer surface of the steel.

[0039] The first moving mechanism 5 includes a threaded rod 502, which is installed on both sides of the outer surface of the base 1 through a transverse groove 501. A moving block 503 is sleeved on the outer surface of the threaded rod 502. The moving block 503 is fixedly connected to the crossbeam 4 through a vertical plate 504. A first motor for rotating the threaded rod 502 is installed on both sides of the rear end face of the base 1. The operation of the first motor can drive the threaded rod 502 to rotate. The outer surface of the threaded rod 502 of the moving block 503 makes linear displacement, which drives the crossbeam 4 to move.

[0040] The second moving mechanism 8 includes a lead screw 802, which is installed on the upper end face of the crossbeam 4 through a strip groove 803. A threaded plate 801 is sleeved on the outer surface of the lead screw 802, and the upper end face of the threaded plate 801 is fixedly connected to the lower end face of the moving seat 6. A motor cavity is provided behind the strip groove 803, and a second motor for rotating the lead screw 802 is installed on the inner wall of the motor cavity. The operation of the second motor can drive the lead screw 802 to rotate, and the threaded plate 801 can make linear displacement on the outer surface of the lead screw 802, thereby driving the moving seat 6 to move back and forth.

[0041] When using this laser cutting equipment for steel processing, first connect the power supply, then place the steel to be cut stably on the honeycomb plate ejector structure 2 set on the base 1. At this time, the honeycomb plate ejector structure 2 plays a core supporting role: conical metal ejector pins 202 are evenly distributed at the hexagonal skeleton nodes of the honeycomb plate 201, and the tip height of the ejector pins 202 is higher than the upper end surface of the honeycomb plate 201. This structural design can minimize the contact area between the ejector pins 202 and the steel to be cut. On the one hand, it avoids the reflected light generated during laser cutting from contacting the steel surface and forming burn marks. On the other hand, it ensures that the steel is supported flatly, effectively preventing the steel from deforming due to uneven force or unstable support during the cutting process, laying the foundation for subsequent precise cutting. After the steel is placed, the pressing mechanisms 3 on both sides of the base 1 and the side limiting mechanism 21 in the groove 20 are activated to perform double positioning and fixing of the steel: the first electric push rod 301 of the pressing mechanism 3 drives the pressure plate 303 to move downward, pressing the steel onto the ejector pin 202 from above; the second electric push rod 2101 of the side limiting mechanism 21 drives the side clamping plate 2102 to move horizontally, limiting the steel from both sides to ensure that the steel does not shift or shake during the cutting process, further improving the cutting accuracy; after positioning, according to the preset steel cutting size and path, the first moving mechanism 5 and the second moving mechanism 8 are activated to adjust the cutting position of the laser head 7. After the laser head 7 is in place, the laser head 7 and the air pump 12 are activated to begin cutting. During steel cutting operations, some of the high-temperature molten slag generated during the cutting process falls below the honeycomb plate 201 through the hexagonal gaps. At this time, the inclined surface 203 inside the honeycomb plate 201 and the high-temperature and wear-resistant coating 204 on the surface can effectively resist the erosion of the high-temperature molten slag, extending the service life of the honeycomb plate pin structure 2. The inclined surface 203 also helps the molten slag to slide down quickly, reducing the accumulation of molten slag inside the honeycomb plate 201. The sliding molten slag will enter the connecting groove 16 through multiple through grooves 15 below the honeycomb plate 201, and then flow into the inclined groove 17 inside the base 1 through the connecting groove 16. Since the bottom surface of the inclined groove 17 is set as an inclined surface, the molten slag will slowly slide down along the inclined bottom surface of the inclined groove 17 under its own gravity, and finally flow into The chip removal groove 18, which is connected to the inclined groove 17, is used to collect molten slag. At the same time, the dust generated during the cutting process is captured in real time by the dust collection mechanism 19. The high-temperature resistant metal grid in the grid groove 1902 first intercepts large molten slag particles in the dust to prevent large impurities from entering the conveying pipe 9 and causing blockage. The air pump 12 forms a stable negative pressure in the filter box 11 and transports the dust captured by the dust collection mechanism 19 to the filter box 11 through the conveying pipe 9. After the dust enters the filter box 11, it is purified by the filter screen 1302 of the filter mechanism 13. The filter screen 1302 can effectively intercept fine dust in the dust to prevent fine dust from entering the air pump 12 and causing wear and damage to the components, thus extending the service life of the air pump 12.To prevent dust from clogging the filter screen 1302 and affecting the dust filtration efficiency, the vibration dust removal mechanism 14 works synchronously: the rotating motor 1403 drives the rotating shaft 1402 and the cam 1401 sleeved on the rotating shaft 1402 to rotate. The cam 1401 drives the moving plate 1404 to move. The arc surface 1409 on the moving plate 1404 pushes the insertion rod 1410 to slide in the through hole 1408 of the fixed plate 1405. The insertion rod 1410 drives the movable plate 1406 and the hammer 1411 to move synchronously. At this time, the spring 1407 undergoes elastic deformation. During the continuous rotation of the cam 1401, the spring 1407 repeatedly resets, driving the hammer 1411 to periodically strike the filter screen 1302, shaking off the dust attached to the surface of the filter screen 1302, ensuring that the filter screen 1302 always remains in good condition. The filtration effect ensures continuous dust capture and filtration, reducing the impact of dust on the working environment and operators. After the cutting operation is completed, the laser head 7, the air pump 12, the rotating motor 1403, and other motors are turned off in sequence. Then, the first electric push rod 301 and the second electric push rod 2101 are started to reset the pressure plate 303 and the side clamping plate 2102, releasing the pressure and limitation on the steel, and removing the cut steel. At the same time, the dust collection shell 1903 is threaded to the cover plate 1901, and the filter mechanism 13 is magnetically connected, facilitating disassembly and maintenance. This invention improves the cutting quality by setting the honeycomb plate pin structure 2 and facilitates the collection and discharge of molten slag generated during cutting. The filter mechanism 13 avoids damage to the air pump 12 and facilitates the cleaning of the filter screen 1302.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
