Description

Technical Field

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

[0002] Stainless steel curtain wall panels, with their corrosion resistance, high strength, excellent appearance, and superior weather resistance, are widely used in the field of architectural curtain wall decoration. They serve multiple functions, including building protection, aesthetic decoration, and structural protection, making them a core material for the facades of modern high-end buildings. In actual production and processing, stainless steel curtain wall panels need to be customized and cut according to the building's dimensions and shape requirements to suit different installation scenarios.

[0003] Currently, the mainstream cutting methods for stainless steel curtain wall panels in the industry are mainly divided into two categories: mechanical cutting and laser cutting. Each of these processes has obvious technical shortcomings. Among them, traditional mechanical cutting is highly stable and has low processing costs, making it suitable for cutting conventional plates. However, it has low processing efficiency and poor cutting accuracy, which can easily cause edge deformation and excessive burrs on the plates. The subsequent grinding process is also cumbersome, making it difficult to meet the processing needs of high precision and irregular shapes.

[0004] Laser cutting, with its advantages of high processing speed, high precision, and high degree of automation, is gradually replacing traditional mechanical cutting as the mainstream processing method. However, this process still has insurmountable technical shortcomings. Laser cutting generates a large amount of heat, and existing equipment cannot quickly cool the cut surface. High temperatures easily lead to thermal deformation and oxidation discoloration of the cut edges of the sheet metal. Simultaneously, the molten slag and impurities produced during cutting are difficult to remove quickly, severely affecting the processing quality of the sheet metal. Furthermore, laser cutting has limitations in processing specifications and a relatively limited cutting range, failing to meet the batch processing needs of large-size and special-specification stainless steel curtain wall panels, thus hindering the large-scale application of stainless steel curtain wall panels in high-end construction. Therefore, how to simultaneously solve the problems of thermal deformation control, slag removal, and limited cutting range during laser cutting is a pressing technical challenge in this field. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that: when existing laser cutting devices cut stainless steel curtain wall panels, heat accumulation causes thermal deformation and oxidation discoloration at the edges of the panels, and the molten slag and impurities generated during cutting cannot be removed in time, affecting the processing quality. Furthermore, the processing specifications are limited and it is difficult to adapt to the flexible processing needs of panels of different sizes.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a laser cutting device for stainless steel curtain wall panels, including a horizontal conveyor frame, an electrically controlled synchronous guide roller group installed on the horizontal conveyor frame, and a laser cutting device body. A top electrically controlled crossbeam is movably installed on the upper end of the horizontal conveyor frame through a top side guide rail, and a top mounting adjustment seat for installing the laser cutting device body is movably assembled on the top electrically controlled crossbeam.

[0007] Furthermore, the top side guide rails are symmetrically fixed on both sides of the upper end of the horizontal conveyor frame.

[0008] Furthermore, the top-mounted electrically controlled crossbeam includes an electrically controlled top adjustment crossbeam, bottom guide blocks fixed to the lower ends of both sides of the electrically controlled top adjustment crossbeam, and embedded lateral adjustment wheels mounted on the bottom guide blocks.

[0009] Furthermore, the electronically controlled top adjusting crossbeam includes a bottom side bracket with a bottom guide block fixed at the lower end, an angle adjustment frame movably mounted on the bottom side bracket, and a lateral support rod for controlling the angle adjustment frame.

[0010] Furthermore, a strip-shaped cutting opening is provided at the center of the upper surface of the angle adjustment frame to cooperate with the laser cutting device.

[0011] Furthermore, the top mounting adjustment seat includes a top mounting seat movably mounted on the upper end of the angle adjustment frame, lateral limiting frames fixed on both sides of the top mounting seat, and support drive wheels mounted on the top mounting seat.

[0012] Furthermore, a strip-shaped assembly hole is provided inside the lateral limiting frame, and a lateral auxiliary wheel is fixedly installed on the lateral limiting frame through the strip-shaped assembly hole.

[0013] Furthermore, an optical positioning probe and a pressure boosting valve nozzle for an external gas-liquid regulating valve are also installed on the outer side of the lateral limiting frame, located on the side of the lateral auxiliary wheel.

[0014] Furthermore, LED supplementary lights can be installed on the outside of the lateral limiting frame via a side-mounted bracket.

[0015] Furthermore, a lateral optical probe for optically identifying the thickness of the stainless steel curtain wall panel is installed on the bottom support.

[0016] The beneficial effects of this invention are as follows: This invention allows the laser cutting device to move freely in the width direction by sliding the top-mounted electrically controlled crossbeam along the top side guide rail, flexibly adapting to stainless steel curtain wall panels of different sizes and specifications, breaking through the limitations of traditional processing specifications; the angle adjustment frame, in conjunction with the lateral support rod, can adjust the cutting angle, enabling complex-shaped irregular cutting and improving processing adaptability; the optical positioning probe accurately positions the cutting position, and the external gas-liquid regulating valve of the pressure booster nozzle sprays cooling medium in real time during the cutting process to cool the cutting surface and blow away molten slag, effectively solving the problems of thermal deformation and impurity residue, and improving cutting quality; the lateral optical probe automatically identifies the plate thickness, enabling adaptive adjustment of cutting parameters, improving automation and processing efficiency.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Figure 1 , Figure 2 , Figure 3 The laser cutting device shown is applied to stainless steel curtain wall panels and includes a horizontal conveyor frame 1, an electrically controlled synchronous guide roller group 2 mounted on the horizontal conveyor frame 1, and a laser cutting device body 3. The horizontal conveyor frame 1 is a horizontally arranged support frame structure, with top side guide rails 4 symmetrically fixed on its upper left and right sides, extending along the length of the horizontal conveyor frame 1. A top electrically controlled crossbeam 5 is slidably mounted on the top side guide rails 4 via bottom guide blocks 8 at both ends. Embedded lateral adjustment wheels 9 are installed on the bottom guide blocks 8, and the lateral adjustment wheels 9 roll in cooperation with the sides of the top side guide rails 4 to ensure that the top electrically controlled crossbeam 5 slides smoothly along the guide rails. The top electrically controlled crossbeam 5 includes an electrically controlled top adjustment crossbeam 7, with a bottom side bracket 10 fixed to the lower end of the electrically controlled top adjustment crossbeam 7, and the lower end of the bottom side bracket 10 is fixedly connected to the bottom guide block 8. An angle adjustment frame 11 is movably mounted on the bottom support 10. A lateral support rod 12 is provided between the bottom support 10 and the angle adjustment frame 11. The tilt angle of the angle adjustment frame 11 can be adjusted by extending and retracting the lateral support rod 12, thereby adjusting the cutting angle of the laser cutting device body 3 to adapt to the cutting needs of stainless steel curtain wall panels with different shapes. A strip-shaped cutting notch 13 is opened in the middle of the upper surface of the angle adjustment frame 11. The strip-shaped cutting notch 13 corresponds vertically to the laser emission port of the laser cutting device body 3 to ensure that the laser beam can pass smoothly through to cut the curtain wall panel below.

[0025] The top mounting adjustment seat 6 includes a top mounting seat 14 movably mounted on the upper end of the angle adjustment frame 11, lateral limiting frames 15 fixed on both sides of the top mounting seat 14, and support drive wheels 16 mounted on the top mounting seat 14. The top mounting seat 14 can slide and adjust longitudinally on the upper end of the angle adjustment frame 11, and the support drive wheels 16 drive the top mounting seat 14 to move, achieving precise control of the cutting position. The lateral limiting frame 15 has a strip-shaped assembly hole 17 inside, and a lateral auxiliary wheel 18 is fixedly mounted on the lateral limiting frame 15 through the strip-shaped assembly hole 17. The lateral auxiliary wheel 18 rolls with the side wall of the laser cutting device body 3, providing auxiliary guidance and stable support for the laser cutting device body 3, ensuring the accuracy of the cutting process. An optical positioning probe 19 and a pressure boosting valve 20 are also installed on the outer side of the lateral limiting frame 15, located on one side of the lateral auxiliary wheel 18. The optical positioning probe 19 is used to accurately position the starting position of the cut. The pressure boosting valve 20 is connected to an external gas-liquid regulating valve. During the cutting process, compressed air or coolant can be sprayed in real time according to the temperature requirements to cool the cutting surface and blow away the molten slag produced during cutting, effectively preventing thermal deformation and oxidation discoloration, and ensuring the cutting quality.

[0026] An LED supplementary light 21 can also be installed on the outside of the lateral limiting frame 15 via a side-mounted bracket. The LED supplementary light 21 provides supplementary lighting for the cutting area, improving the operator's observation conditions and enhancing operational safety. A lateral optical probe 22 is installed on the bottom bracket 10. The lateral optical probe 22 is used to optically identify the thickness of the stainless steel curtain wall panel. The system automatically adjusts parameters such as laser power, cutting speed, and cooling medium flow rate based on the detected thickness information to achieve adaptive cutting control, improving processing efficiency and yield. The electrically controlled synchronous guide roller group 2 consists of multiple synchronously driven guide rollers, responsible for smoothly conveying the stainless steel curtain wall panel along the length of the horizontal conveyor frame 1 to the cutting station, ensuring stable positioning and continuous feeding of the panel during the cutting process.

[0027] The working principle and process of this invention are as follows: Before operation, according to the specifications and dimensions of the stainless steel curtain wall panel to be processed, the top-mounted electric control beam 5 is adjusted to a suitable position by controlling the top adjusting beam 7 to slide along the top side guide rail 4; the tilt angle of the angle control frame 11 is adjusted by the side support rod 12 to align the laser cutting device body 3 with the cutting start position. During operation, the stainless steel curtain wall panel is conveyed to the horizontal conveyor frame 1 by the electric control synchronous guide roller group 2. The side optical probe 22 detects the thickness of the panel in real time and feeds the data back to the control system, which automatically matches the laser power and cutting speed parameters. After the optical positioning probe 19 accurately positions the cutting start point, the laser cutting device body 3 starts the cutting operation. At the same time, the pressure boosting valve nozzle 20 sprays cooling medium to cool and remove slag from the cutting surface in real time according to the control signal. During the cutting process, the support drive wheel 16 drives the top mounting seat 14 to move along the angle control frame 11, driving the laser cutting device body 3 to complete the cutting path along the preset trajectory. After the cutting is completed, the next panel to be processed is conveyed to the position by the guide roller group, and the above steps are repeated to achieve continuous batch processing.

[0028] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
