Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting and forming equipment for metal decorative panels. Background Technology

[0002] Metal decorative panels are a type of building decoration material made of thin metal sheets (such as aluminum alloy, stainless steel, galvanized steel sheets, etc.) as the surface layer and supplemented with a backing material. Due to their advantages such as light weight, high strength, fire resistance, moisture resistance, rich colors, and modern decorative effects, they are widely used in building curtain walls, interior ceilings, wall decoration, and decoration projects in various commercial spaces. In actual construction, decorative panels need to be cut according to the wall size, installation location, and corner shape. For flat extensions, they only need to be cut straight along the length. However, at the external corners, internal corners, and various bends of the wall, the panels need to be cut into L-shaped sections with specific angles to achieve corner coverage and aesthetic connection.

[0003] Through in-depth research, the inventors of this application discovered that on-site cutting heavily relies on the technical experience and operational proficiency of workers, and the accuracy of cutting angles and dimensions is difficult to guarantee—especially at inside and outside corners, where it is necessary to simultaneously control the angle of the cutting line (usually 45° or 135°) and the length of the board. Even if workers pre-mark lines with a ruler, deviations can still easily occur when manually advancing the cutting, resulting in skewed cuts or angle deviations, ultimately causing excessive gaps or mismatches when adjacent boards are spliced. Summary of the Invention

[0004] This invention provides a laser cutting and forming equipment for metal decorative panels, which aims to solve the problems of existing technologies where on-site cutting relies on manual experience, has insufficient precision, requires consideration of both cutting angle and length at inside and outside corners, and is prone to deviation during manual cutting, resulting in excessively large or non-sealed splicing seams.

[0019] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see the appendix Figure 1 -Appendix Figure 12 This invention provides a metal decorative panel laser cutting forming equipment, including a base plate 1, a machine tool 2, a first guide rail 3, a gantry frame 4, a second guide rail 5, a laser cutting head 6, a lifting unit 7, a pressing and fixing unit 8, and a V-groove opening unit 9; The base plate 1 is horizontally set on the ground to support and fix the entire equipment. The machine tool 2 is fixedly installed on the top of the base plate 1. The top surface of the machine tool 2 is the working surface for placing the metal decorative plate to be processed. The two opposite sides of the machine tool 2 are respectively fixedly installed with first guide rails 3. The two first guide rails 3 are parallel and symmetrically arranged. The gantry 4 spans across the machine tool 2, and the two ends of the gantry 4 are slidably connected to the first guide rails 3 on both sides. The gantry 4 can slide back and forth along the first guide rails 3 in the length direction of the machine tool 2. The outer side of the gantry 4 is provided with a second guide rail 5. The second guide rail 5 extends horizontally along the length direction of the gantry 4. The laser cutting head 6 is slidably installed on the second guide rail 5. The laser cutting head 6 can slide back and forth along the second guide rail 5 in the length direction of the gantry 4. With the cooperation of the first guide rail 3 and the second guide rail 5, the laser cutting head 6 can achieve two-dimensional movement in the X and Y directions in the horizontal plane, thereby performing laser cutting on the plate with arbitrary trajectory. The machine tool 2 is equipped with a lifting unit 7, which is used to lift a part of the plate upward so that the part of the plate is removed from the working surface of the machine tool 2. A pressing and fixing unit 8 is provided on one side of the machine tool 2, which is used to press and fix the part of the plate that is removed from the working surface of the machine tool 2. A V-groove unit 9 is also provided on the gantry frame 4, which is used to process a V-groove on the part of the plate that is removed from the working surface of the machine tool 2.

[0021] Please see Figure 2 and Figure 3 The lifting unit 7 includes a horizontal plate 701, a first electric push rod 702, and a first connecting block 703. The machine tool 2 has an installation cavity inside. A vertically movable saw blade is embedded in the center area of ​​the working surface of the machine tool 2. The saw blade is part of the working surface of the machine tool 2 and is used to support the plate. The horizontal plate 701 is horizontally fixedly connected to the installation cavity of the machine tool 2, and the two ends of the horizontal plate 701 are respectively fixedly connected to the inner walls of the left and right sides of the machine tool 2. The horizontal plate 701 is located directly below the saw blade. The first electric push rod 702 is fixedly installed at the bottom of the horizontal plate 701. The fixed end of the first electric push rod 702 is fixedly connected to the horizontal plate 701. The telescopic end of the first electric push rod 702 extends upward in the vertical direction. The telescopic end of the first electric push rod 702 passes through the horizontal plate 701 and is fixedly connected to the bottom of the saw blade through the first connecting block 703. When the telescopic end of the first electric push rod 702 extends upward, it pushes the saw blade upward through the first connecting block 703. The saw blade detaches from the working surface of the machine tool 2 and lifts a portion of the sheet material placed on it upward, thus detaching that portion of the sheet material from the working surface of the machine tool 2. When the telescopic end of the first electric push rod 702 retracts downward, it drives the saw blade downward to reset, and the saw blade falls back to a position flush with the working surface of the machine tool 2. The telescopic stroke of the first electric push rod 702 can be controlled according to the required lifting height.

[0022] Please see the appendix Figure 3 -Appendix Figure 4 The pressing and fixing unit 8 includes a bearing plate 801, a support bar 802, a rotating bar 803, a pressure block 804, and a second electric push rod 805; The support plate 801 is fixedly connected to the top of one side of the machine tool 2. The support plate 801 extends outward in the horizontal direction. The support bar 802 is fixedly connected to the outer edge of the support plate 801. The support bar 802 is set in the vertical direction. The middle part of the rotating bar 803 is hinged to the support bar 802 through a pin. The rotating bar 803 can rotate around the hinge point in the vertical plane. One end of the rotating bar 803 (i.e. the end closer to the machine tool 2) is fixedly connected to a pressure block 804. The pressure block 804 is located directly above the working surface of the machine tool 2. The other end of the rotating bar 803 (i.e. the end away from the machine tool 2) is hinged to the support plate 801 with a second electric push rod 805. When the telescopic end of the second electric push rod 805 retracts, the second electric push rod 805 pulls the rotating bar 803 to rotate around its hinge point with the support bar 802. The end of the rotating bar 803 near the machine tool 2 swings downward, driving the pressure block 804 to move downward until the pressure block 804 is tightly pressed against the upper surface of the lifted plate. At this time, the plate is clamped between the first connecting block 703 of the lifting unit 7 and the pressure block 804 of the pressing and fixing unit 8, achieving reliable fixation. When the telescopic end of the second electric push rod 805 extends, the rotating bar 803 rotates in the opposite direction, and the pressure block 804 is lifted upward, releasing the pressure on the plate.

[0023] Please see the appendix Figure 5 There are two vertical frames 401. The two vertical frames 401 are slidably connected to the first guide rails 3 on both sides. Each vertical frame 401 can slide along the corresponding first guide rail 3, thereby realizing the movement of the gantry frame 4 as a whole along the length of the machine tool 2. A crossbeam 402 is set on the top of two vertical frames 401. The two ends of the crossbeam 402 are slidably connected to the corresponding vertical frames 401 through guide rods 10. Specifically, each vertical frame 401 has a guide hole at its top. One end of the guide rod 10 is fixedly connected to the end of the crossbeam 402, and the other end of the guide rod 10 is slidably inserted into the corresponding guide hole. A fourth electric push rod 11 is fixedly installed on the outside of both vertical frames 401. The telescopic end of the fourth electric push rod 11 extends vertically and is fixedly connected to the end of the crossbeam 402.

[0024] When the two fourth electric push rods 11 move synchronously, the telescopic end of the fourth electric push rod 11 extends or retracts, driving the crossbeam 402 to slide up and down relative to the vertical frame 401 through the guide rod 10, thereby realizing the height adjustment of the crossbeam 402. The second guide rail 5 is fixedly installed at the bottom of the crossbeam 402. The second guide rail 5 extends horizontally along the length of the crossbeam 402. A slide block 12 is slidably connected inside the second guide rail 5. The slide block 12 can slide back and forth along the second guide rail 5 in the length of the crossbeam 402. The laser cutting head 6 is fixedly installed directly below the slide block 12. When the slide block 12 moves, it drives the laser cutting head 6 to move synchronously.

[0025] Please see Figures 6 to 11 The V-groove unit 9 includes a third electric push rod 901, a rotating plate 902, a sliding plate 904, a first drive motor 905, a turntable 906, a pull rod 907, a telescopic rod 908, a sliding member 909, a spring 912, a vertical strip plate 914, a milling cutter 915, and a drive assembly 916. The third electric push rod 901 is fixedly installed on the side of the slide block 12. The telescopic end of the third electric push rod 901 extends horizontally. The telescopic end of the third electric push rod 901 is hinged to one end of the rotating plate 902 through a hinge. The middle part of the rotating plate 902 is hinged to the slide block 12 through a hinge. The rotating plate 902 can rotate in the vertical plane around its hinge point with the slide block 12. The slide plate 904 is disposed on one side of the rotating plate 902. Specifically, a groove 903 is provided on one side surface of the rotating plate 902. The groove 903 extends along the length direction of the rotating plate 902. The slide plate 904 is slidably connected in the groove 903. The slide plate 904 can slide back and forth along the groove 903 in the length direction of the rotating plate 902. The first drive motor 905 is fixedly installed on the outer surface of the rotating plate 902. The output shaft of the first drive motor 905 extends in a direction perpendicular to the surface of the rotating plate 902. The output end of the first drive motor 905 is fixedly connected to the turntable 906. The turntable 906 is coaxially fixed with the output shaft of the first drive motor 905. A pull rod 907 is eccentrically provided on the outer surface of the turntable 906. One end of the pull rod 907 is rotatably connected to the turntable 906, and the other end of the pull rod 907 is hinged to the slide plate 904. When the telescopic end of the third electric push rod 901 extends or retracts, the third electric push rod 901 pushes the rotating plate 902 to rotate around its hinge point with the slide block 12, thereby adjusting the tilt angle of the rotating plate 902 and thus adjusting the machining angle of the milling cutter 915.

[0026] When the first drive motor 905 starts, it drives the turntable 906 to rotate. Since the pull rod 907 is eccentrically set on the turntable 906, when the turntable 906 rotates, it drives the slide plate 904 to slide back and forth along the slide groove 903 through the pull rod 907. The back and forth sliding of the slide plate 904 further drives the milling cutter 915 to reciprocate.

[0027] Please see Figures 7 to 9 The bottom of the slide plate 904 is fixedly connected to the fixed end of the telescopic rod 908. The telescopic rod 908 extends downward in a direction perpendicular to the slide plate 904. The movable end of the telescopic rod 908 is connected to the sliding member 909. The telescopic rod 908 can extend and retract along its axis to compensate for the displacement changes of the sliding member 909 during the movement. A second connecting block 910 is fixedly connected to the outer side of the fixed end of the telescopic rod 908, and a third connecting block 911 is fixedly connected to the outer side of the sliding member 909. A spring 912 is fixedly connected between the second connecting block 910 and the third connecting block 911. The spring 912 is sleeved on the outer side of the telescopic rod 908. One end of the spring 912 is fixedly connected to the second connecting block 910, and the other end of the spring 912 is fixedly connected to the third connecting block 911. The sliding member 909 includes a first follower plate 9091, a sliding column 9092, and a second follower plate 9093. The first follower plate 9091 and the second follower plate 9093 are respectively disposed on opposite sides of the rotating plate 902. A V-shaped groove 913 is provided on the rotating plate 902, and the V-shaped groove 913 penetrates the front and rear surfaces of the rotating plate 902. The sliding column 9092 passes through the V-shaped groove 913 and can slide within the V-shaped groove 913. One end of the sliding column 9092 is fixedly connected to the first follower plate 9091, and the other end of the sliding column 9092 is fixedly connected to the second follower plate 9093. A third connecting block 911 is fixedly connected to the outside of the first follower plate 9091. A spring 912 is elastically connected to the first follower plate 9091 through the third connecting block 911. When the slide plate 904 slides back and forth along the slide groove 903, the slide plate 904 drives the first follower plate 9091 to move synchronously through the telescopic rod 908. The first follower plate 9091 drives the second follower plate 9093 to move synchronously through the slide column 9092. When the slide column 9092 slides in the V-groove 913, it is guided and constrained by the V-groove 913, making the movement trajectory of the slider 909 more precise. The spring 912 provides elastic restoring force during the movement of the slider 909, making the reciprocating movement of the slider 909 more stable.

[0028] The bottom of the second follower plate 9093 is fixedly connected to a vertical strip plate 914, which extends downward in the vertical direction. A milling cutter 915 is provided on the outer side of the vertical strip plate 914. The milling cutter 915 is used to mill the plate. The milling cutter 915 is driven to rotate by the drive assembly 916.

[0029] Please see Figures 8 to 11 The drive assembly 916 includes a second drive motor 9161, a first pulley 9162, a belt 9163, and a second pulley 9164; The second drive motor 9161 is fixedly installed on the outer side of one end of the vertical strip 914. The output shaft of the second drive motor 9161 passes through the vertical strip 914 and extends to the other side of the vertical strip 914. The output end of the second drive motor 9161 is fixedly connected to a first rotating wheel 9162. The first rotating wheel 9162 is connected to a second rotating wheel 9164 via a belt 9163. The second rotating wheel 9164 is rotatably set at the lower end of the vertical strip 914. The second rotating wheel 9164 is fixedly connected to a milling cutter 915. The diameter of the milling cutter 915 is larger than the diameter of the second rotating wheel 9164.

[0030] When the second drive motor 9161 starts, it drives the first rotating wheel 9162 to rotate. The first rotating wheel 9162 drives the second rotating wheel 9164 to rotate via the belt 9163. The second rotating wheel 9164 drives the milling cutter 915, which is fixedly connected to it, to rotate synchronously. Since the diameter of the milling cutter 915 is larger than the diameter of the second rotating wheel 9164, the milling cutter 915 has a higher linear speed during rotation, which can efficiently mill the metal decorative panel. In actual use, the first drive motor 905 drives the slide plate 904 to slide back and forth, which in turn drives the vertical strip plate 914 and the milling cutter 915 to move back and forth, performing reciprocating milling on the plate. At the same time, the second drive motor 9161 drives the milling cutter 915 to rotate at high speed to achieve milling. By controlling the speed of the first drive motor 905, the reciprocating frequency of the milling cutter 915 can be adjusted, thereby controlling the surface quality of the V-groove.

[0031] It should be noted that the rotating wheel 9164 is fixedly connected to the milling cutter 915. The milling cutter 915 rotates synchronously with the rotating wheel 9164. The lower end of the vertical plate 914 rotatably supports the rotating wheel 9164 and the milling cutter 915. By replacing the milling cutter 915 with different specifications or adjusting the installation position of the milling cutter 915, the machining width and depth of the V-groove can be changed.

[0032] In addition, a protective shell 917 is fixedly connected to the outside of the vertical strip 914. The protective shell 917 has a hollow shell structure and is installed on the outside of the drive assembly 916. The protective shell 917 is used to protect the belt 9163 and the moving parts of the drive assembly 916 from the intrusion and damage of cutting chips, thus extending the service life of the equipment. At the same time, the protective shell 917 is also used to push the V-shaped waste material formed after the milling cutter 915 cuts, preventing the waste material from getting stuck between the milling cutter 915 and the plate, thus realizing the automatic separation and discharge of the waste material. The actions of all the electric linear actuators and drive motors mentioned above can be automatically controlled by a PLC controller or CNC system. Operators only need to input the corresponding processing parameters (including laser cutting trajectory, lifting height, plate turning angle, milling depth, etc.) through the control panel, and the equipment can automatically complete all the above processes. For plates of different specifications and processing requirements, flexible adaptation can be achieved by changing the 915 milling cutter or adjusting the stroke of each electric linear actuator.

[0033] Workflow: Place the metal decorative panel to be processed flat on the working surface of machine tool 2. Adjust the position of the panel so that the edge of the panel to be processed with the V-groove is aligned with the saw blade in the center area of ​​the working surface of machine tool 2, ensuring that the panel covers all or part of the saw blade area. Start the gantry 4 to slide along the first guide rail 3, and simultaneously start the slide block 12 to slide along the second guide rail 5. Move the laser cutting head 6 to directly above the position to be cut on the panel. Start the fourth electric push rod 11. The extension or retraction end of the fourth electric push rod 11 extends or retracts, driving the crossbeam 402 to slide up and down relative to the vertical frame 401 through the guide rod 10. Adjust the laser cutting head 6 to a suitable height, start the laser cutting head 6, and the laser cutting head 6 pre-cuts the panel along the preset cutting trajectory, shaping the panel outline. Alternatively, the excess portion to be removed can be pre-cut through or have dividing lines cut out, separating the area to be bent and the waste area on the board. After this pre-cutting step, the board is still placed as a whole on the working surface of machine tool 2, but the area to be bent and the waste area have been separated by the cutting seam. The first electric push rod 702 of the lifting unit 7 is activated, and the telescopic end of the first electric push rod 702 extends upward, pushing the saw blade upward through the first connecting block 703. The saw blade detaches from the working surface of machine tool 2 and removes part of the board placed on it from the working surface of machine tool 2. The second electric push rod 805 of the pressing and fixing unit 8 is activated, and the telescopic end of the second electric push rod 805 retracts, pulling the rotating bar 803 around it and the support bar 802. The hinge point rotates, and the end of the rotating bar 803 near the machine tool 2 swings downward, driving the pressure block 804 to move downward until the pressure block 804 is tightly pressed against the upper surface of the lifted plate. At this time, the plate is clamped between the saw blade of the lifting unit 7 and the pressure block 804 of the pressing and fixing unit 8, and the bending area is reliably fixed to ensure that the plate will not be displaced during the subsequent V-groove processing. The third electric push rod 901 is activated, and the extension or retraction end of the third electric push rod 901 extends or retracts, pushing the rotating plate 902 to rotate around its hinge point with the slide 12 to a predetermined angle, so that the milling cutter 915 is aligned with the position to be processed on the plate (the inner edge of the cutting seam formed by laser pre-cutting). Then, the second drive motor 9161 is activated, and the second drive motor 9161 drives the rotating wheel. Rotating wheel 9162 drives rotating wheel 9164 via belt 9163. Rotating wheel 9164 drives milling cutter 915, which is fixedly connected to it, to rotate at high speed. Then, the first drive motor 905 is started, which drives turntable 906 to rotate. Since the pull rod 907 is eccentrically set on turntable 906, when turntable 906 rotates, it drives slide plate 904 to slide back and forth along slide groove 903 via pull rod 907. Slide plate 904 drives first follower plate 9091 to move synchronously via telescopic rod 908. First follower plate 9091 drives second follower plate 9093 to move synchronously via slide column 9092. Second follower plate 9093 drives vertical strip plate 914 and milling cutter 915 to move back and forth, performing reciprocating milling on the plate.A V-shaped groove is machined on the portion of the sheet metal that detaches from the working surface of the machine tool 2. Spring 912 provides elastic restoring force during the movement of sliding component 909, making the reciprocating motion smoother. During machining, protective shell 917 protects the belt 9163 and the moving parts of the drive assembly 916 from the intrusion and damage of cutting debris, extending the service life of the equipment. Simultaneously, it pushes the V-shaped waste material formed after the milling cutter 915 cuts, preventing the waste material from getting stuck between the milling cutter 915 and the sheet metal, thus achieving automatic separation and discharge of the waste material.
