Description

Technical Field

[0001] This invention relates to the field of curtain wall cutting technology, and in particular to a laser cutting device for curtain wall steel structures. Background Technology

[0002] As a key load-bearing and decorative component of modern building envelope systems, curtain wall steel structures are characterized by their lightweight structure, free-form design, and excellent mechanical properties. They are widely used in high-rise buildings, large public facilities, and landmark buildings. Their components are typically made of tubular materials (square and round tubes), structural steel sections (H-shaped and box-shaped), and irregularly shaped curved steel plates. They must meet requirements for high-precision dimensions, complex cuts, and high-quality cut surfaces. Traditional processing methods mainly rely on mechanical punching and shearing, flame cutting, or plasma cutting. However, these technologies have many limitations. Mechanical punching and shearing are suitable for straight lines or simple curves, but lack the ability to process complex three-dimensional curves. While flame cutting and plasma cutting can handle thicker steel, they result in a large heat-affected zone, and the cut is prone to hardening and thermal deformation, severely affecting the welding performance and dimensional stability of the steel structure. To improve cutting quality, laser cutting has been developed for curtain wall steel structures. Laser cutting offers advantages such as narrow kerfs, small heat-affected zones, and high precision.

[0003] A search revealed Chinese patent application number 202022053931.1, which discloses a laser cutting device for steel structures. The device includes a base, a support bracket connected to the top of the base, a support plate connected to the top of the support bracket, a sliding groove connected to the top of the base, a first motor connected to the front of the sliding groove, a first lead screw connected to the output end of the first motor, a first slider connected to the surface of the first lead screw, a hydraulic cylinder connected to the top of the first slider, and a hydraulic rod connected to the top of the hydraulic cylinder. This laser cutting device for steel structures, as described in the patent, has the following shortcomings: The existing device lacks an effective adjustment component, making it impossible to adjust the position of the workpiece to be cut as needed. For some long workpieces, the inability to effectively adjust the position prevents cutting at the designated location, leading to cutting dead angles and severely impacting cutting efficiency. Summary of the Invention

The output end of one side of the hydraulic cylinder is slidably inserted through the support plate. A mounting seat is provided at the end of the hydraulic cylinder, and an adjustment motor is provided on the top of the mounting seat. The output end of the adjustment motor is connected to a fixed shaft, one end of which is rotatably inserted through the mounting seat. An adjustment frame is provided on the fixed shaft, and a fixed frame is provided at the end of the adjustment frame. A motor compartment is provided on the top of the fixed frame, and several sets of connecting shafts are connected to the output end of the motor compartment. One end of the connecting shaft is rotatably inserted through the fixed frame, and a rotating wheel is provided on the connecting shaft. A moving component for movement and a conveying component for transport are provided on one side of the support plate.

[0006] As a further embodiment of the present invention: the moving component includes an electric slide table, and two sets of electric slide tables are provided, which are symmetrically installed on the top of two sets of support plates respectively. A moving frame is connected to one side of the electric slide table, and a mounting groove is opened on one side of the moving frame. An electric slide base is embedded in the mounting groove. A support base is provided on one side of the electric slide base, and a laser cutting component for cutting is provided on one side of the support base.

[0007] As a further embodiment of the present invention: the laser cutting assembly includes an electric lifting rod, which is installed at the bottom of the support base, and a laser cutting machine is provided at the bottom end of the electric lifting rod.

[0008] As a further embodiment of the present invention: the conveying assembly includes a drive chamber, which is installed on one side of the support plate. The output end of one side of the drive chamber is connected to several sets of transmission shafts. One end of the transmission shaft is rotatably disposed through the support plate. The transmission shaft is provided with a conveying roller, which is arranged in a circle and has several sets of anti-slip textures.

[0009] As a further embodiment of the present invention: a fixed bracket is provided on the top of the support plate, a water storage tank is provided on the top of the fixed bracket, a water inlet is connected to the top of the water storage tank, a water pump is provided at the bottom of the fixed bracket, the water pump is connected to the water storage tank, a spray frame is connected to the output end at the bottom of the water pump, and a number of spray holes are opened at the bottom of the spray frame.

[0010] As a further embodiment of the present invention: a connecting bracket is provided on one side of the fixed bracket, and a cylinder is embedded in the bottom of the connecting bracket, and a cleaning brush is detachably installed at the bottom of the cylinder.

[0011] As a further embodiment of the present invention: the top of the support base is provided with a drainage groove, and the drainage groove is provided with a number of drainage holes arranged in sequence, the size and position of the drainage groove being adapted to the spray frame.

[0012] As a further embodiment of the present invention: the bottom of the support base is provided with two sets of pull-out sliding grooves, through which a pull-out frame is slidably arranged, and a water collection box is provided at the bottom of the pull-out frame, the size and position of the water collection box being adapted to the drainage groove.

[0013] As a further embodiment of the present invention: the bristles at the bottom of the cleaning brush have grooves, and the grooves are in the shape of a continuous mountain character.

[0014] As a further embodiment of the present invention: a control panel is provided on one side of the support plate, and a light-shielding frame is provided on the other side of the support plate, the size and position of the light-shielding frame being adapted to the control panel.

[0015] The beneficial effects of this invention are as follows: 1. The position of the curtain wall steel structure can be conveniently adjusted by setting the adjustment component. By adjusting its position and controlling its displacement, it can be quickly adjusted to the specified cutting position as needed. This solves the problem that existing devices cannot effectively adjust the position of the curtain wall steel structure. It can avoid cutting dead angles when the curtain wall steel structure is too long, which affects the cutting efficiency. At the same time, the adjustment component can also adaptively adjust the angle of the curtain wall steel structure. It can correct deviations when they occur, thereby avoiding unnecessary defects caused by the deviation of the cutting position and ensuring the quality of the cutting process.

[0016] 2. By setting up a spray frame to spray and rinse the curtain wall steel structure, efficient cleaning can be achieved, which can effectively remove impurities and stains attached to its surface, thereby avoiding affecting the laser cutting effect.

[0017] 3. By setting up cleaning brushes, the curtain wall steel structure can be further cleaned on the basis of spray rinsing, which can effectively remove stubborn impurities and dirt.

[0018] 4. The continuous mountain-shaped grooves on the cleaning brush can effectively improve the cleaning effect. Traditional brush bristles have a small contact area with the cleaning surface, resulting in poor cleaning effect. However, the mountain-shaped grooves form multiple longitudinal ridges and grooves on the brush bristles. When the cleaning brush bristles rub against the surface of the curtain wall steel structure, these extra edges act like miniature scrapers or blades, which can more effectively cut into and scrape away stubborn stains and impurities.

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1: A laser cutting device for curtain wall steel structures, such as Figure 1-8As shown, the system includes an adjustment assembly, which includes a support base 1. Two sets of support plates 19 are symmetrically arranged on the top of the support base 1. Several sets of hydraulic cylinders 4 are arranged in parallel on one side of the support plates 19. The output end of one side of the hydraulic cylinder 4 can slide through the support plate 19. A mounting seat 22 is provided at the end of the hydraulic cylinder 4. An adjustment motor 23 is provided on the top of the mounting seat 22. A fixed shaft 25 is connected to the bottom output end of the adjustment motor 23. One end of the fixed shaft 25 can rotatably pass through the mounting seat 22. An adjustment frame 24 is provided on the fixed shaft 25. A fixed frame 10 is provided at the end of the adjustment frame 24. A motor compartment 11 is provided on the top of the fixed frame 10. Several sets of connecting shafts 7 are connected to the bottom output end of the motor compartment 11. One end of the connecting shaft 7 can rotatably pass through the fixed frame 10. A rotating wheel 9 is provided on the connecting shaft 7. A moving assembly for movement and a conveying assembly for conveying are provided on one side of the support plate 19. In use, the conveying assembly supports the curtain wall steel structure while simultaneously conveying it. During conveying, the hydraulic cylinder 4 activates the rotating wheel 9, controlling its movement to ensure it contacts both sides of the steel structure for positioning. This prevents the steel structure from shifting during transport. The rotating wheel 9 is made of rubber, minimizing pressure and preventing damage from excessive pressure on the steel structure. The hydraulic cylinder 4 allows for targeted adjustment of the rotating wheel 9's position based on the steel structure's dimensions, preventing issues caused by insufficient contact and positioning if the structure is too small. After contact, the motor in the motor compartment 11 activates the connecting shaft 7 and the rotating wheel 9, controlling their rotation. This movement of the rotating wheel 9 moves the steel structure, and the direction of movement can be adjusted by switching its rotation direction. Controlling its displacement allows for rapid adjustment to a designated cutting position, solving the problem of existing devices being unable to effectively adjust the position of the steel structure and preventing over-positioning. Prolonged cutting dead angles affect cutting efficiency. The positioning of the rotating wheel 9 prevents deviation during movement and corrects any misalignment of the curtain wall steel structure, effectively improving laser cutting precision and preventing unnecessary defects. When the curtain wall steel structure deviates, the motor 23 starts, controlling the rotation of the fixed shaft 25 and the adjusting frame 24. Adjusting the angle of the adjusting frame 24 simultaneously adjusts the angles of the fixed frame 10 and the rotating wheel 9, allowing the rotating wheel 9 to be adjusted to match the deviated curtain wall steel structure. After adjustment, the hydraulic cylinder 4 controls the rotating wheel 9 to move and contact the curtain wall steel structure. Once in contact and positioned, the hydraulic cylinder 4 adjusts the position of the rotating wheel 9 in conjunction with the rotation of the adjusting frame 24 to quickly correct the deviated curtain wall steel structure, preventing the cutting position from shifting due to the deviation. This allows for rapid adjustment of the curtain wall steel structure position and convenient angle adjustment, ensuring laser cutting precision, guaranteeing cutting quality, and preventing unnecessary defects. The moving component includes an electric slide table 12, which is provided in two sets and symmetrically installed on the top of two sets of support plates 19. A moving frame 13 is connected to one side of the electric slide table 12. An installation groove is provided on one side of the moving frame 13, through which an electric slide base 29 is embedded. A support base 26 is provided on one side of the electric slide base 29, and a laser cutting component for cutting is provided on one side of the support base 26. In use, the movable frame 13 can be moved by starting the electric slide table 12, and the support base 26 can be moved by starting the electric slide base 29 embedded in the movable frame 13. The position of the laser cutting component can be easily adjusted by moving the movable frame 13 and the support base 26, and it can be moved conveniently along the X and Y axes. This allows the laser cutting component to be moved precisely along the cutting position of the curtain wall steel structure, so as to complete the cutting process quickly and with high precision. Its multi-directional movement can further avoid the occurrence of cutting dead angles. The laser cutting assembly includes an electric lifting rod 27, which is installed at the bottom of the support base 26, and a laser cutting machine 28 is provided at the bottom of the electric lifting rod 27. In use, the laser cutting machine 28 can be moved in a targeted manner according to the cutting position by moving the movable frame 13 and the support base 26. The laser cutting machine 28 can be started to perform convenient and fast cutting of the curtain wall steel structure. During cutting, the movement of the laser cutting machine 28 can be controlled to cut the appropriate shape as needed. The height of the laser cutting machine 28 can be adjusted by the electric lifting rod 27. By adjusting the height of the laser cutting machine 28, it can be adapted to curtain wall steel structures of different thicknesses, avoiding the problem that the fixed height of the laser cutting machine 28 will affect the normal cutting of thinner curtain wall steel structures. The conveying assembly includes a drive chamber 20, which is installed on one side of the support plate 19. The output end of the drive chamber 20 is connected to several sets of drive shafts 33. One end of the drive shaft 33 is rotatably installed through the support plate 19. The drive shaft 33 is equipped with a conveying roller 8, which is arranged in a circle and has several sets of anti-slip textures. In use, the conveyor roller 8 is made of rubber. The drive shaft 33 and the conveyor roller 8 can be rotated by starting the motor in the drive chamber 20. The rotation of the conveyor roller 8 can support and transport the curtain wall steel structure. When transporting the curtain wall steel structure, one end can be placed on the conveyor roller 8. After placement, the conveyor roller 8 can be rotated to transport it conveniently. At the same time, it can provide stable support for the curtain wall steel structure when cutting and adjusting the position. The rubber material combined with the anti-slip texture can increase the friction when in contact with the curtain wall steel structure, thereby avoiding slippage during transport. To remove impurities, such as Figure 1 , 5 As shown in Figure 8, a fixed bracket 18 is provided on the top of the support plate 19, a water storage tank 17 is provided on the top of the fixed bracket 18, a water inlet 15 is connected to the top of the water storage tank 17, a water pump 30 is provided at the bottom of the fixed bracket 18, the water pump 30 is connected to the water storage tank 17, and a spray frame 31 is connected to the output end of the bottom of the water pump 30. Several sets of spray holes are opened at the bottom of the spray frame 31. During use, a sealing plug is provided on one side of the water inlet 15. The sealing plug can seal the water inlet 15, preventing impurities from entering and causing blockage when no water is added. After removing the sealing plug and adding water to the water storage tank 17 through the water inlet 15, the water pump 30 can be started to transport the water in the water storage tank 17. The water can be transported to the spray frame 31 and sprayed out through several sets of spray holes at its bottom. The sprayed water can spray and clean the curtain wall steel structure as it is being transported, effectively removing stains and impurities attached to its surface, thus avoiding the presence of impurities and stains that may affect the laser cutting effect. The spray frame 31 is located above the conveyor roller 8, which can efficiently clean the surface of the curtain wall steel structure. To further remove impurities, such as Figure 5 , 6 As shown in Figure 8, a connecting bracket 14 is provided on one side of the fixed bracket 18, and a cylinder 16 is embedded in the bottom of the connecting bracket 14. A cleaning brush 32 is detachably installed at the bottom of the cylinder 16. During use, the cleaning brush 32 can be quickly installed and removed from the end of the cylinder 16. It is fixed by simple bolts. The cleaning brush 32 can be installed according to the size of the curtain wall steel structure. After installation, the cleaning brush 32 can be controlled to fall by starting the cylinder 16. As the cleaning brush 32 falls, the bristles at the bottom of the cleaning brush 32 can come into contact with the curtain wall steel structure. After the initial cleaning of the curtain wall steel structure is completed by water spraying, the cleaning brush 32 can be used to clean it further. This can avoid the problem of stubborn impurities and stains remaining. When the curtain wall steel structure is moved, the cleaning brush 32 can sweep away impurities, stains and water stains, which makes it easier to laser cut it. To remove wastewater, such as Figure 5 , 6 As shown, the top of the support base 1 is provided with a drainage groove 21, and the drainage groove 21 is provided with a number of drainage holes arranged in sequence. The size and position of the drainage groove 21 are adapted to the spray frame 31. During use, the wastewater generated during the spray rinsing will flow downwards and can flow into the drainage trough 21 at the bottom for quick discharge. The wastewater carrying impurities and stains swept away by the cleaning brush 32 will also flow into the drainage trough 21. After flowing in, the cleaned impurities and stains can be carried away from the drainage hole and quickly discharged, thereby avoiding the situation where a lot of wastewater and impurities accumulate and affect normal cutting. In order to collect wastewater, such as Figure 5 , 6 As shown, the bottom of the support base 1 is provided with two sets of pull-out sliding grooves, through which a pull-out bracket 3 is slidably installed. A water collection box 2 is provided at the bottom of the pull-out bracket 3. The size and position of the water collection box 2 are adapted to the drainage groove 21. During use, a pull ring is provided on one side of the water collection box 2. By holding the pull ring, the water collection box 2 can be pulled out for cleaning. During installation, the pull-out bracket 3 can be aligned with the pull-out slide and inserted. After installation, the installation of the water collection box 2 is completed. After installation, the water collection box 2 is located below the drain trough 21. Wastewater flowing out of the drain trough 21 can enter the water collection box 2 for collection. After a large amount is collected, it can be cleaned in a centralized manner. After the wastewater is collected, it can be filtered and purified. After purification, it can be reused, which can increase the utilization rate of water resources and avoid unnecessary waste. To enhance the cleaning effect of brush 32, such as Figure 7 As shown, the bristles at the bottom of the cleaning brush 32 have grooves, and the grooves are in a continuous mountain-shaped pattern. When in use, the cleaning brush 32 with continuous mountain-shaped grooves can effectively improve the cleaning effect. Traditional brush bristles have a small contact area with the cleaning surface, resulting in poor cleaning effect. However, the mountain-shaped grooves form multiple longitudinal ridges and grooves on the bristles. When the bristles of the cleaning brush 32 rub against the surface of the curtain wall steel structure, these extra ridges act like miniature scrapers or blades, which can more effectively cut into and scrape away stubborn stains and impurities. While improving the cleaning effect, the grooves can also form a temporary storage space for impurities, which can prevent the cleaning brush 32 from brushing the impurities back onto the curtain wall steel structure when it moves.

[0024] Example 2: For ease of control, refer to Figure 1 A laser cutting device for curtain wall steel structure. This embodiment makes the following improvements compared to embodiment 1: a control panel 6 is provided on one side of the support plate 19, and a light shield 5 is provided on one side of the support plate 19. The size and position of the light shield 5 are adapted to the control panel 6. When in use, the control panel 6 can be covered by the light shield 5 to block the light, thus preventing glare from affecting the view when operating the control panel 6. The control panel 6 is connected to various components by wires. The start, stop and power of each component can be easily controlled through the control panel 6. The internal controller can quickly identify and process the control signals to achieve control of each component.
