Hyperboloid aluminum plate numerical control laser cutting device and method thereof

Abstract

This invention belongs to the field of CNC laser cutting technology, specifically disclosing a CNC laser cutting device for hyperboloid aluminum plates. The device includes a processing table, with a slide rail at one end. A movable frame is slidably mounted on the upper end of the slide rail, and a crossbar rail is installed on the upper end of the movable frame. A controller is installed at one end of the crossbar rail, a main driver is installed at the rear end of the crossbar rail, and a cutting auxiliary component is installed at the front end of the crossbar rail. This invention simultaneously creates a sealed negative pressure space during the cutting process. The high-temperature molten slag generated during cutting is immediately absorbed and collected by the negative pressure, preventing slag from splashing and adhering to the aluminum plate surface. This eliminates the problems of residual heat deformation of the base material and kerf deformation caused by high-temperature slag residue, effectively ensuring the regularity of the kerf shape, improving the processing accuracy of the aluminum plate and the surface quality of the finished product, and solving the drawbacks of traditional equipment where molten slag retention affects processing quality.

Description

Technical Field

[0001] This invention belongs to the field of CNC laser cutting technology, and specifically discloses a CNC laser cutting device and method for hyperboloid aluminum plates. Background Technology

[0002] Hyperbolic aluminum sheet is a new type of building material. Its main appearance feature is the design of a hyperbolic shape, which has a very high decorative effect and aesthetic appeal. When processing hyperbolic aluminum sheet, a laser cutting device is required to cut the aluminum coil into small pieces of aluminum sheet. Then, the cut pieces of aluminum sheet are processed into hyperbolic shapes using a mold. Previously, CNC laser cutting equipment for hyperboloid aluminum plates was widely used in hyperboloid aluminum plate processing due to the popularization of laser technology. Currently, conventional laser cutting equipment mostly uses a method of mounting the cutting head perpendicular to the workpiece surface to complete the cutting operation. However, in the actual processing, when the high-energy-density laser beam acts on the aluminum plate, it will instantly melt the material and generate a large amount of high-temperature slag. Some of the slag will splash and adhere to the workpiece surface due to the vaporization recoil force. If it is not cleaned in time during the cutting process, the residual heat of the slag will continue to affect the surrounding base material, eventually leading to deformation of the cut shape and a decrease in processing accuracy, which directly affects the cut performance and surface quality of the finished product. Summary of the Invention

[0013] A method for CNC laser cutting hyperboloid aluminum plates is also provided, for operating a CNC laser cutting device for hyperboloid aluminum plates, comprising the following steps: S1: Place the aluminum plate to be processed on the processing table and align it with the cleaning wheel and grinding wheel. Drive the mounting base downwards, causing the cutting head, protective cover, and suction chamber to move downwards synchronously, calibrating the vertical processing distance between the cutting head and the aluminum plate. The rubber contact ring at the bottom of the suction chamber transforms into a sealed processing space. Use four sets of indicators to align with the preset cutting line to complete the processing positioning. S2: Start the cutting head for laser cutting, and simultaneously turn on the air pump to create negative pressure inside the protective cover and suction chamber. The cutting slag is quickly sucked into the collection chamber through the suction hole to achieve real-time slag removal. At the same time, the motor is started, and the cleaning wheel and grinding wheel are driven by the belt to complete the pre-dust removal of the cutting area and the real-time grinding and trimming of the cut. The operator can observe the processing status in real time through the transparent panel. S3: After the aluminum plate is cut, start the air blower to blow away the residual residue inside the suction chamber and the protective cover. The residue enters the collection chamber with the negative pressure airflow and is intercepted and filtered by the filter element. Regularly replacing the filter element can stabilize the slag removal effect. For aluminum plates of different specifications, the distance between the cleaning wheel and the grinding wheel can be adjusted by rotating the threaded shaft, and the belt tension can be adjusted by the threaded rod to adapt to the processing needs of different workpieces.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By placing the aluminum plate to be processed on the upper part of the processing table, the aluminum plate is made to fit against the cleaning wheel and the grinding wheel; the mounting base is moved down to drive the cutting head, protective cover and suction chamber downward, and the vertical distance between the cutting head and the aluminum plate is adjusted to the process standard. The rubber contact ring is deformed to form a sealed space in the suction chamber; with the help of four sets of indicators with different arrangements, the pre-cutting line is preset for the aluminum plate to complete the positioning calibration before cutting. Laser cutting of aluminum plates is initiated by activating the cutting head, and simultaneously the vacuum pump is turned on. The vacuum is conducted through pipelines to create negative pressure inside the suction chamber and protective cover, and the molten slag is promptly sucked into the collection chamber through the suction holes. Simultaneously, the motor is started, and the cleaning wheel and grinding wheel are driven by belt drive. The cleaning wheel removes dust and impurities from the cutting area in advance, and the grinding wheel polishes and trims the newly formed cut edge in real time. The operator can observe the entire cutting process through the viewing plate, and a closed negative pressure space can be created simultaneously during the cutting process. The high-temperature molten slag generated during cutting is immediately sucked in and collected by the negative pressure, preventing slag from splashing and adhering to the surface of the aluminum plate. This eliminates the problems of high-temperature residue heat deformation of the base material and cut deformation, effectively ensuring the regularity of the cut shape, improving the processing accuracy of the aluminum plate and the surface quality of the finished product, and solving the drawbacks of slag retention affecting the processing quality of traditional equipment. After the aluminum plate is cut, the air blower is activated to blow the residue remaining in the chamber upwards. The residue enters the collection chamber with the negative pressure airflow and is intercepted and collected by the filter element. The filter element can be replaced periodically to maintain the residue collection capacity. If it is necessary to process double-curved aluminum plates of different specifications and thicknesses, the distance between the cleaning wheel, the grinding wheel and the suction chamber can be adjusted by rotating the threaded shaft, and the belt tension can be changed by adjusting the threaded rod to adapt to different workpiece processing conditions.

A suction hole 712 is opened on the inner wall of the suction chamber 79. A vent hole 713 is opened at the upper end of the air blower 711. An indicator needle 714 is fixedly installed at one end of the suction chamber 79. The control component 8 includes a limiting plate 81 fixedly mounted at the rear end of the docking plate 12. A sliding chamber 82 is fixedly mounted at the lower end of the limiting plate 81. A docking shaft 83 is movably mounted inside the sliding chamber 82. A movable shaft 84 is movably mounted on the inner side of the sliding chamber 82 near the docking shaft 83. A first slot 85 is fixedly mounted on the outer side of the docking shaft 83 near the front side of the sliding chamber 82. A second slot 86 is fixedly mounted on the outer side of the movable shaft 84 near the front side of the sliding chamber 82. A cleaning wheel 87 is fixedly mounted on the outer side of the docking shaft 83 near the front side of the first slot 85. A cleaning wheel 87 is fixedly mounted on the outer side of the movable shaft 84 near the front side of the second slot 86. There is a grinding wheel 88. A belt 89 is driven on the outer side of the first slot 85. A fixed frame 810 is fixed on the upper end of the sliding chamber 82. A threaded shaft 811 is movably arranged on the inner side of the fixed frame 810. A control frame 812 is threadedly connected to the outer side of the threaded shaft 811 near the fixed frame 810. A third slot 813 is driven on the inner side of the belt 89 near the upper side of the first slot 85. A drive shaft 814 is fixed on the inner side of the third slot 813. An adjustment frame 815 is movably arranged on the outer side of the drive shaft 814 near the front side of the third slot 813. A threaded rod 816 is threaded on the inner side of the adjustment frame 815. One end of the auxiliary driver 9 is installed at the other end of the processing table 1, and one end of the linkage 10 is installed at one end of the main driver 6.

[0020] A vacuum pump 715 is installed through the front end of the collection chamber 71, and a filter element 716 is installed at the front end of the vacuum pump 715. A connecting line 717 is installed at the upper end of the cutting head 74. A fixing rod 719 is fixedly installed at the upper end of the protective cover 78. The axis of the protective cover 78, the suction chamber 79, the contact ring 710, and the cutting head 74 are located on the same straight line. The main body of the contact ring 710 is made of rubber. There are several sets of suction holes 712 and four sets of indicator needles 714. Two sets of indicator needles 714 are parallel to the crossbar rail 4, and the other two sets of indicator needles 714 are perpendicular to the crossbar rail 4. The upper end of the fixing rod 719 is fixedly connected to the lower end of the mounting base 73.

[0021] In use, the operator places the hyperboloid aluminum plate to be processed on the processing table 1, ensuring the aluminum plate aligns with the cleaning wheel 87 and the grinding wheel 88. The drive mounting base 73 moves downwards, causing the cutting head 74, protective cover 78, and suction chamber 79 to descend synchronously. The vertical processing distance between the cutting head 74 and the aluminum plate surface is precisely adjusted. During this process, the rubber contact ring 710 at the bottom of the suction chamber 79 deforms under pressure, forming a sealed protective space with the aluminum plate processing surface. This, along with two sets of parallel and two sets of perpendicular indicator pins 714 aligned with the preset cutting line, completes the processing positioning calibration. After positioning, the cutting head 74 is started for laser cutting, and simultaneously the front end of the collection chamber 71 is opened. The air extractor 715 creates a negative pressure airflow inside the equipment pipeline. The airflow is conducted through the corrugated pipe 72, connecting pipe 75, docking chamber 76, and suction pipe 77 to the protective cover 78 and suction chamber 79. The high-temperature molten metal slag and residue generated during cutting can be quickly sucked into the collection chamber 71 through multiple suction holes 712 on the side wall of the suction chamber 79 under negative pressure. This effectively avoids slag splashing and adhesion to the plate, and eliminates problems such as deformation of the base material and irregular cut caused by residual heat from the residue. This ensures cutting accuracy and finished product quality. During operation, the operator can observe the cutting condition in real time through the transparent plate 718 embedded in the protective cover 78. The sealed chamber can isolate the processing area, taking into account both environmental cleanliness and operational safety.

[0022] A mounting bracket 817 is fixedly installed on the upper end of the docking plate 12. A motor 818 is installed at the front end of the drive shaft 814. The main body of the limiting plate 81 is L-shaped, and there are two sets of the main body of the limiting plate 81. The outer side of the second slot 86 is connected to the inner side of the belt 89 near the first slot 85. The first slot 85, the second slot 86, and the third slot 813 form a triangle. The outer side of the cleaning wheel 87 is made of plush material, and the outer side of the grinding wheel 88 is made of silicon carbide abrasive. The docking shaft 83 passes through the interior of the control frame 812, and the docking shaft 83 moves with the control frame 812. The control frame 812 has two sets of connections. The movable shaft 84 passes through the interior of the other control frame 812 and is movably connected to the other control frame 812. The outer side of the threaded shaft 811 has two kinds of bidirectional threads, and the thread direction of the connection between the threaded shaft 811 and the two control frames 812 is different. The threaded rod 816 passes through the interior of the mounting frame 817 and is movably connected to the mounting frame 817. One end of the motor 818 is fixedly connected to one end of the control frame 815. The grinding wheel 88 and the cleaning wheel 87 are located on one side and the other side of the suction chamber 79.

[0023] The cutting operation is synchronized with the start of motor 818. Motor 818 drives the third slot 813 to rotate through drive shaft 814. Relying on the transmission action of the first slot 85, second slot 86, third slot 813 arranged in a triangle and belt 89, the docking shaft 83 and the movable shaft 84 are driven to rotate synchronously, driving the cleaning wheel 87 and the grinding wheel 88 to work synchronously. The cleaning wheel 87, made of plush material, can clean the dust and impurities in the aluminum plate cutting area in advance to eliminate processing obstacles. The grinding wheel 88, made of silicon carbide abrasive, can grind and trim the cut edge of the aluminum plate in real time. Through the dual process of pre-cleaning and post-grinding, the flatness and processing accuracy of the aluminum plate cutting are effectively improved.

[0024] A method for CNC laser cutting hyperboloid aluminum plates is also provided, for operating a CNC laser cutting device for hyperboloid aluminum plates, comprising the following steps: S1: Place the aluminum plate to be processed on the processing table 1 and align it with the cleaning wheel 87 and the grinding wheel 88. Drive the mounting base 73 downwards, causing the cutting head 74, the protective cover 78, and the suction chamber 79 to move downwards synchronously, calibrating the vertical processing distance between the cutting head 74 and the aluminum plate. A sealed processing space is formed by the deformation of the rubber contact ring 710 at the bottom of the suction chamber 79. Use four sets of indicator pins 714 to align with the preset cutting line to complete the processing positioning. S2: Start the cutting head 74 to perform laser cutting, and simultaneously turn on the air extraction fan 715 to create negative pressure inside the protective cover 78 and the suction chamber 79. The cutting slag is quickly sucked into the collection chamber 71 through the suction hole 712 to achieve real-time slag removal. At the same time, the motor 818 is started, and the cleaning wheel 87 and the grinding wheel 88 are driven by the belt 89 to complete the pre-dust removal of the cutting area and the real-time grinding and trimming of the cut. The operator can observe the processing status in real time through the transparent plate 718. S3: After the aluminum plate is cut, the air blower 711 is activated to blow away the residual residue inside the suction chamber 79 and the protective cover 78. The residue enters the collection chamber 71 with the negative pressure airflow and is intercepted and filtered by the filter element 716. The slag removal effect can be stabilized by replacing the filter element 716 regularly. For aluminum plates of different specifications, the spacing between the cleaning wheel 87 and the grinding wheel 88 can be adjusted by rotating the threaded shaft 811, and the tension of the belt 89 can be adjusted by the threaded rod 816 to adapt to the processing needs of different workpieces.

[0025] Working Principle: During use, the operator places the hyperboloid aluminum plate to be processed on the processing table 1, ensuring the aluminum plate aligns with the cleaning wheel 87 and the grinding wheel 88. The driving mounting base 73 moves downwards, causing the cutting head 74, protective cover 78, and suction chamber 79 to descend synchronously. The vertical processing distance between the cutting head 74 and the aluminum plate surface is precisely adjusted. During this process, the rubber contact ring 710 at the bottom of the suction chamber 79 deforms under pressure, forming a sealed protective space with the aluminum plate processing surface. This, combined with four sets of indicator pins 714 (two sets parallel and two sets perpendicular to the crossbar rail 4), aligns with the preset cutting line, completing the processing positioning calibration. After positioning, the cutting head 74 is started for laser cutting. Simultaneously, the air extractor 715 at the front end of the collection chamber 71 is turned on, creating a negative pressure airflow inside the equipment pipeline. The airflow passes through the wave... The cutting tube 72, connecting tube 75, docking chamber 76, and suction tube 77 conduct heat to the protective cover 78 and the suction chamber 79. The high-temperature molten metal slag and residue generated during cutting can be quickly sucked into the collection chamber 71 by multiple suction holes 712 on the side wall of the suction chamber 79 under negative pressure. This effectively avoids slag splashing and adhesion to the plate, and eliminates problems such as deformation of the base material and irregular cut caused by residual heat from the residue, ensuring cutting accuracy and finished product quality. During operation, the operator can observe the cutting condition in real time through the viewing plate 718 embedded in the protective cover 78. The sealed chamber can isolate the processing area, taking into account both environmental cleanliness and operational safety. The cutting operation is synchronized with the start of the motor 818. The motor 818 drives the third slot 813 to rotate through the drive shaft 814, relying on the first slot 85 and the second slot 813 arranged in a triangle. The transmission action of slot 86, slot 813, and belt 89 drives the docking shaft 83 and movable shaft 84 to rotate synchronously, causing the cleaning wheel 87 and grinding wheel 88 to work synchronously. The cleaning wheel 87, made of plush material, can pre-clean the dust and impurities in the aluminum plate cutting area to eliminate processing obstacles. The grinding wheel 88, made of silicon carbide abrasive, can grind and trim the cut edges of the aluminum plate in real time. Through the dual process of pre-cleaning and post-grinding, the flatness and processing accuracy of the aluminum plate cutting are effectively improved. After a batch of cutting operations is completed, the air blower 711 at the bottom of the suction chamber 79 is activated. It blows the residual residue in the chamber upward through the upper vent 713, so that the residual impurities are collected into the collection chamber 71 with the negative pressure airflow. Finally, they are filtered by the filter element 716 at the front end of the air extractor 715. The filter element 716 can be replaced periodically by staff to ensure stable operation of the equipment's residue collection function. For processing hyperboloid aluminum plates of different specifications and thicknesses, the bidirectional threaded shaft 811 inside the rotating fixed frame 810 can be used to drive two sets of control frames 812 to move relative to or away from each other using the reverse thread structure at both ends. This drives the docking shaft 83 and the movable shaft 84 to slide within the sliding chamber 82, precisely adjusting the distance between the cleaning wheel 87, the grinding wheel 88, and the suction chamber 79. Simultaneously, rotating the threaded rod 816 on the mounting frame 817 moves the control frame 815, adjusting the position of the motor 818 and the third slot 813, and adjusting the tension of the belt 89 to ensure stable operation of the transmission structure. This allows the equipment to adapt to different workpiece processing conditions, effectively broadening the applicability of the device.

10. A method for CNC laser cutting of hyperboloid aluminum plates, used to operate the CNC laser cutting device for hyperboloid aluminum plates as described in any one of claims 1-9, characterized in that... Includes the following steps: S1: Place the aluminum plate to be processed on the processing table (1) and attach it to the cleaning wheel (87) and the grinding wheel (88). Drive the mounting base (73) downward, which will drive the cutting head (74), the protective cover (78) and the suction chamber (79) to move down synchronously. Align the vertical processing distance between the cutting head (74) and the aluminum plate. A closed processing space is formed by the deformation of the rubber contact ring (710) at the bottom of the suction chamber (79). Use four sets of indicator pins (714) to align with the preset cutting line to complete the processing positioning. S2: Start the cutting head (74) for laser cutting, and simultaneously turn on the air pump (715) to create a negative pressure inside the protective cover (78) and suction chamber (79). The cutting slag is quickly sucked into the collection chamber (71) through the suction hole (712) to achieve real-time slag removal. At the same time, start the motor (818), which drives the cleaning wheel (87) and grinding wheel (88) to rotate via the belt (89) to complete the pre-dust removal of the cutting area and the real-time grinding and trimming of the cut. The operator can observe the processing status in real time through the viewing plate (718). S3: After the aluminum plate is cut, start the air blower (711) to blow away the residue inside the suction chamber (79) and the protective cover (78). The residue enters the collection chamber (71) with the negative pressure airflow and is intercepted and filtered by the filter element (716). The slag removal effect can be stabilized by regularly replacing the filter element (716). For aluminum plates of different specifications, the distance between the cleaning wheel (87) and the grinding wheel (88) can be adjusted by rotating the threaded shaft (811), and the tension of the belt (89) can be adjusted by the threaded rod (816) to adapt to the processing requirements of different workpieces.
