Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting process and laser cutting equipment for deep processing of aluminum alloys. Background Technology

[0002] Laser equipment is widely used in the manufacturing of metal cutting and welding equipment, such as intelligent welding systems and plasma arc welding machines. Among these, aluminum alloys require laser cutting equipment for deep processing. Aluminum alloys have strength close to that of high-alloy steel, specific stiffness exceeding that of steel, good casting and plastic processing properties, good electrical and thermal conductivity, good corrosion resistance and weldability, and can be used as structural materials. They have wide applications in aerospace, aviation, transportation, construction, electromechanical, light chemical and daily consumer goods. Laser cutting uses a high-power-density laser beam to irradiate the material being cut, quickly heating it to its vaporization temperature and evaporating it to form a hole. As the beam moves across the material, the holes continuously form a very narrow kerf, completing the cutting of the material.

[0003] When cutting aluminum alloy materials, existing laser cutting equipment first needs to clamp and fix the material, and then adjust the position of the laser device. During the cutting process, a dust collection device is generally needed to absorb the debris and dust generated during cutting. In the existing technology, different clamps are required for different aluminum alloy materials. For example, the clamps for plate-shaped and round tube-shaped materials are different. Therefore, before each use, it is necessary to select a suitable clamp according to the shape of the material to clamp and fix it, which is quite inconvenient. Summary of the Invention

[0009] Furthermore, the collection assembly also includes a scraper. The scraper is provided at one end of the collection frame away from the collection box.

[0010] Furthermore, a baffle is provided at one end of the collection frame near the collection box, and insert rods are fixed at both ends of the baffle. The insert rods are slidably inserted into both sides of the collection frame, and the insert rods are fixedly connected to the collection frame by springs. Two top posts are symmetrically fixed on the surface of the scraper.

[0011] Furthermore, the bottom of the table panel near the baffle is provided with an inclined plate, the top of the scraper is fixed with an inclined block, and when the scraper moves to the vicinity of the baffle, the inclined block slides in contact with the inclined surface of the inclined plate.

[0014] A laser cutting process for deep machining of aluminum alloys, the laser cutting process comprising the following steps:

[0015] (1) Design the machining area for slots on aluminum alloy sheet material and write the corresponding machining program;

[0016] (2) Use fixing components to wrap and clamp the aluminum alloy sheet material onto the protrusions on the tabletop;

[0017] (3) Adjust the height of the laser cutting head, focus and align the blade, and open the high-pressure gas valve to blow the high-pressure gas toward the focal point of the laser cutting.

[0018] (4) Move the laser cutting head to cut. After the cutting is completed at this point, adjust the focal length and move the laser cutting head to another point on the aluminum alloy plate material to focus and cut.

[0019] (5) After cutting, the collecting component collects the debris and dust generated during cutting and sends them out in a concentrated manner. Simultaneously, the fixing component releases the material from its clamping position and removes the aluminum alloy material from the tabletop.

[0020] The beneficial effects of this invention are:

[0021] 1. The present invention allows the height of the top frame to be adjusted via a first electric push rod, facilitating the processing of aluminum alloy materials of different heights by the laser cutting head. A moving block connects the vertical frame and the collection frame, and a motor drives the first screw to rotate. The moving block and the first screw cooperate to slide along the moving notch, and the collection frame and the vertical frame move synchronously. The vertical frame on the other side of the top frame slides along the side moving groove, and the fan slides along the bottom moving groove, making it convenient to adjust the cutting position according to the position of the aluminum alloy material.

[0022] 2. In this invention, when the scraper is located at one end of the collection frame, the back of the scraper is also fixedly connected to the collection frame by a spring. The platform moves downward by the elastic force of four spring telescopic columns, separating from the protrusion. At this time, it is the cutting stage. The two ends of the collection frame are sealed by the scraper and the baffle respectively. The dust is concentrated inside the collection frame. After the cutting is completed, the electric winding seat winds up the pull rope, pulling the scraper to slide along the surface of the collection frame, pushing the debris and dust inside the collection frame towards the baffle side. When the top column contacts the baffle, the inclined block also slides into contact with the inclined surface of the inclined plate. As the scraper continues to move, the platform is squeezed upward and returns to the state of being flush with the protrusion. At the same time, the top column squeezes the baffle to move outward, and the two side inserts of the baffle slide out along the collection frame until the scraper pushes the dust inside the collection frame into the collection box. Then the scraper and the baffle are reset by their respective springs. During the rotation of the winding shaft of the electric winding seat, because of the connection between the third screw and the winding shaft, the clamping and loosening of the aluminum alloy material by the fixing component is carried out simultaneously with the cleaning inside the collection frame.

[0023] 3. In this invention, the upper limit rod rises away from the pressure plate with the second electric push rod, and the lower limit rod is pushed upward by the third electric push rod to lift the pressure plate. At the same time, the third screw rotates, and the connecting plate drives the bottom plate to move upward, moving the position of multiple pressure plates to a higher position to facilitate the placement of aluminum alloy materials. Then, before cutting, the table panel needs to move downward, the scraper returns to one end of the collection frame, the third screw drives the connecting plate to move downward, and the bottom plate pulls the pressure plate downward through the connecting rope. At the same time, the third electric push rod drives the lower limit rod to descend, reducing the height of the pressure plate so that the pressure plate contacts the top of the aluminum alloy material. The two sets of moving frames are moved by the second screw, and the upper limit rod is driven by the second electric push rod to squeeze and limit the upper part of the pressure plates on both sides of the aluminum alloy material, so that the pressure plates tightly wrap around the outer periphery of the aluminum alloy material. Because the pressure plates are connected by a connecting piece, it can be used for wrapping different shapes. After wrapping tightly, it is cut by a laser cutting head, saving the time of changing fixtures.

[0024] 4. Compared with the prior art, the present invention collects and organizes the smoke and debris generated during cutting through the collection component, and automatically cleans the debris in the collection frame after cutting. It also works with the fixing component to wrap and clamp the aluminum alloy material, making it suitable for cutting materials of different shapes. Attached Figure Description

Connecting ropes 47 are fixed at both ends of the base plates 48. The connecting ropes 47 are fixedly connected to the bottommost pressure plates 41 at both ends of the fixing components 4. When using the device, the aluminum alloy material is placed on the table panel 11. Then the table panel 11 is lowered and the material is supported by the protrusions 12. The gap between the protrusions 12 can avoid damage to the table surface by laser cutting. The fixing components 4 clamp and fix the material in a wrapping manner according to the shape of the material. The material is cut by the laser cutting head 22. The dust and smoke generated by cutting are collected through the collection components 3 and the through holes on the table panel 11 and concentrated into the collection box 39 to avoid contamination of the table surface.

[0045] In this embodiment, a first electric push rod 23 is fixed inside the vertical frame 21, and the extended end of the first electric push rod 23 is fixedly connected to the top frame 2. A laser cutting head 22 is mounted on the bottom surface of the top frame 2 via a screw device. A first screw 15 is rotatably mounted inside the movable notch at one end of the connection between the collection frame 32 and the vertical frame 21 on the cutting table 1, and a movable block 16 is threaded onto the surface of the first screw 15. The collection frame 32, the vertical frame 21, and the movable block 16 are fixedly connected. A side movable groove 14 is provided on the top of the movable notch on the other side of the cutting table 1. The vertical frame 21 slides along the side movable groove 14. The bottom of the cutting table 1 has three bottom moving slots 13, and the fan 31 slides along the bottom moving slots 13. The height of the top frame 2 can be adjusted by the first electric push rod 23, which makes it convenient for the laser cutting head 22 to process aluminum alloy materials of different heights. The vertical frame 21 and the collection frame 32 are connected by the moving block 16, and then the first screw 15 is driven to rotate by the motor. The moving block 16 and the first screw 15 cooperate to slide along the moving notch. The collection frame 32 and the vertical frame 21 move synchronously. The vertical frame 21 on the other side of the top frame 2 slides along the side moving slot 14, and the fan 31 slides along the bottom moving slot 13, which makes it convenient to adjust the cutting position according to the position of the aluminum alloy material.

[0046] In this embodiment, the collection component 3 further includes a scraper 33. A scraper 33 is provided at the end of the collection frame 32 away from the collection box 39. Pull ropes 313 are fixed to both ends of the scraper 33. Two electric winding seats 310 are fixedly installed on the outer surface of the collection box 39. The pull ropes 313 are wound onto the winding shaft of the electric winding seats 310. A baffle 38 is provided at the end of the collection frame 32 near the collection box 39, and insert rods 312 are fixed to both ends of the baffle 38. The insert rods 312 are slidably inserted into both sides of the collection frame 32, and are fixedly connected to the collection frame 32 by springs. Two top posts 35 are symmetrically fixed on the surface of the scraper 33. An inclined plate 19 is provided at the bottom of the table panel 11 near the baffle 38. An inclined block 34 is fixed to the top of the scraper 33, and when the scraper 33 moves to the vicinity of the baffle 38, the inclined block 34 slides into contact with the inclined surface of the inclined plate 19. A groove 18 is provided at the bottom of the table panel 11 corresponding to the position of the inclined plate 19, and the top of the inclined plate 19 slides along the groove 18. Spring telescopic posts 17 are fixed at the four corners of the bottom of the table panel 11, and the bottom of the spring telescopic posts 17 is fixedly connected to the cutting table 1. When the scraper 33 is located at one end of the collection frame 32, the scraper... The back of plate 33 is also fixedly connected to the collection frame 32 by springs. The table panel 11 moves downward by the elastic force of the four spring telescopic columns 17 and separates from the protrusion 12. At this time, it is the cutting stage. The two ends of the collection frame 32 are sealed by scraper 33 and baffle 38 respectively. Dust is concentrated inside the collection frame 32. After cutting, the electric winding seat 310 winds up the pull rope 313 and pulls the scraper 33 to slide along the surface of the collection frame 32, pushing the debris and dust inside the collection frame 32 toward the baffle 38. When the top column 35 contacts the baffle 38, the inclined block 34 also slides against the inclined surface of the inclined plate 19. Upon contact, as the scraper 33 continues to move, the platform 11 is pressed upwards, returning to a state flush with the protrusion 12. Simultaneously, the top column 35 presses the baffle 38 to move outwards, and the two side inserts 312 of the baffle 38 slide out along the collection frame 32 until the scraper 33 pushes the dust in the collection frame 32 into the collection box 39. Subsequently, the scraper 33 and the baffle 38 are reset by their respective springs. During the rotation of the electric winding seat 310 winding shaft, because the third screw 43 is connected to the winding shaft, the clamping and loosening of the aluminum alloy material by the fixing component 4 is carried out simultaneously with the cleaning inside the collection frame 32.

[0047] In this embodiment, the fixing component 4 further includes a connecting plate 411. A third screw 43 is rotatably mounted on the bottom of the electric winding seat 310. The connecting plate 411 is threaded onto the surface of the third screw 43. Both ends of the connecting plate 411 are fixedly connected to two base plates 48. Second screws 311 are rotatably mounted on both sides of the top frame 2 via bearings. The second screws 311 are bidirectional screws. The two ends of the second screws 311 are symmetrically threaded onto movable frames 44. The outer ends of the movable frames 44... A second electric push rod 45 is fixed, and an upper limit rod 46 is fixed to the extended end of the second electric push rod 45. A third electric push rod 49 is fixed to the outside of the vertical frame 21, and a lower limit rod 410 is fixed to the extended end of the third electric push rod 49. The upper limit rod 46 and the lower limit rod 410 slide in contact with the top and bottom of the pressure plate 41, respectively. In the initial state, the upper limit rod 46 rises away from the pressure plate 41 with the second electric push rod 45, and the lower limit rod 410 is pushed by the third electric push rod 49 to move the pressure plate 41 towards... The plate is lifted up, and at the same time, the third screw 43 rotates, causing the connecting plate 411 to move the bottom plate 48 upward, moving the position of the multiple pressure plates 41 to a higher position to facilitate the placement of aluminum alloy materials. Before cutting, the table panel 11 is moved downward, the scraper 33 returns to one end of the collection frame 32, the third screw 43 moves the connecting plate 411 downward, and the bottom plate 48 pulls the pressure plates 41 downward through the connecting rope 47. At the same time, the third electric push rod 49 drives the lower limit rod 410 to descend, reducing the height of the pressure plates 41 so that the pressure plates 41 contact the top of the aluminum alloy materials. The two sets of moving frames 44 are moved by the second screw 311, and the upper limit rod 46 is driven by the second electric push rod 45 to squeeze and limit the upper ends of the pressure plates 41 on both sides of the aluminum alloy materials, so that the pressure plates 41 tightly wrap around the outer periphery of the aluminum alloy materials. Since the pressure plates 41 are rotatably connected by the connecting piece 42, they can be used for wrapping different shapes. After wrapping tightly, the laser cutting head 22 cuts the material, saving time for changing fixtures.

[0048] When using the device, the aluminum alloy material is placed on the table panel 11. The height of the top frame 2 can be adjusted by the first electric push rod 23, which facilitates the laser cutting head 22 to process aluminum alloy materials of different heights. The vertical frame 21 and the collection frame 32 are connected by the moving block 16, and then the first screw 15 is driven to rotate by the motor. The moving block 16 and the first screw 15 cooperate to slide along the moving notch. The collection frame 32 and the vertical frame 21 move synchronously. The vertical frame 21 on the other side of the top frame 2 slides along the side moving groove 14, and the fan 31 slides along the bottom moving groove 13, which facilitates the adjustment of the cutting position according to the position of the aluminum alloy material. Then the table panel 11 is lowered, and the material is supported by the protrusions 12. The gap between the protrusions 12 can prevent the laser cutting from hitting the table. In the initial state, the upper limit rod 46 rises away from the pressure plate 41 with the second electric push rod 45, and the lower limit rod 410 is pushed by the third electric push rod 49 to lift the pressure plate 41 upward. At the same time, the third screw 43 rotates, and the connecting plate 411 drives the bottom plate 48 to move upward, moving the position of multiple pressure plates 41 to a higher position to facilitate the placement of aluminum alloy materials. Then, before cutting, the table panel 11 needs to move downward, the scraper 33 returns to one end of the collection frame 32, the third screw 43 drives the connecting plate 411 to move downward, and the bottom plate 48 pulls the pressure plate 41 downward through the connecting rope 47. At the same time, the third electric push rod 49 drives the lower limit rod 410 to descend, reducing the height of the pressure plate 41, so that the pressure plate 41 and the aluminum alloy are in contact. The top of the aluminum alloy material contacts the material. The second screw 311 moves two sets of moving frames 44, and the second electric push rod 45 drives the upper limit rod 46 to press and limit the upper ends of the pressure plates 41 on both sides of the aluminum alloy material. This ensures the pressure plates 41 tightly wrap around the aluminum alloy material. Because the pressure plates 41 are rotatably connected by connectors 42, it can be used for wrapping in different shapes. After tight wrapping, the material is cut by the laser cutting head 22, saving time on changing clamps. After cutting, the electric winding seat 310 winds up the pull rope 313, pulling the scraper 33 to slide along the surface of the collection frame 32, pushing debris and dust inside the collection frame 32 towards the baffle 38. When the top post 35 contacts the baffle 38, the inclined block 34 also slides into contact with the inclined surface of the inclined plate 19. As the scraper 33 continues to move, the tabletop 11 is squeezed upward and moves back to the state of being flush with the protrusion 12. At the same time, the top post 35 squeezes the baffle 38 to move outward, and the two side inserts 312 of the baffle 38 slide out along the collection frame 32 until the scraper 33 pushes the dust in the collection frame 32 into the collection box 39. Then the scraper 33 and the baffle 38 are reset by their respective springs. During the rotation of the electric winding seat 310 winding shaft, because the third screw 43 is connected to the winding shaft, the clamping and loosening of the aluminum alloy material by the fixing component 4 is carried out simultaneously with the cleaning of the inside of the collection frame 32, so as to avoid contamination of the tabletop.
