Description

Technical Field

[0001] This invention belongs to the technical field of laser cutting machines for aluminum tube processing, specifically relating to a laser cutting device for aluminum profile processing. Background Technology

[0002] Cutting is a crucial step in aluminum profile processing. Common cutting methods include electric sawing, stamping, plasma cutting, and laser cutting. Among these, laser cutting, with its significant advantages of high efficiency, high precision, and low energy consumption, is gradually replacing traditional cutting methods and becoming the mainstream choice for aluminum profile processing. A laser cutting machine for aluminum profile processing is a high-precision CNC device specifically designed for cutting aluminum alloy profiles. It uses a high-energy laser beam to perform non-contact cutting of aluminum, possessing characteristics such as high efficiency, precision, and flexibility. During laser cutting of aluminum profiles, the profile is first rotated by an electric clamp, and then the laser cutting mechanism cuts it. Due to aluminum's high thermal conductivity and low melting point, tiny weld slags and molten slags are easily generated at the laser-cut edges, affecting the product's appearance and assembly accuracy. In such cases, manual grinding or the use of files, sandpaper, or a dedicated weld slag removal machine is required. Manual grinding requires the operator to manually refine the surface with files and sandpaper, which is not only inefficient but also results in poor consistency. A dedicated weld slag removal machine transfers the aluminum profiles to a separate machine for secondary processing after cutting, which undoubtedly increases production cycle time and logistics costs.

[0003] A laser cutting device for aluminum profile processing, with announcement number CN120038454A, currently exists. Existing such devices use a torsion spring between a fixed plate and the laser cutting head, creating an elastic connection between the shearing needle and the laser cutting head. This allows the shearing needle to move along the same path as the laser cutting head. A conical surface on the outer wall of the shearing needle, combined with a second spring, exerts downward force, squeezing the shearing needle into the cutting kerf of the aluminum profile. This achieves simultaneous laser cutting and grinding. The second spring also drives the shearing needle at the top of the cutting waste to push it downwards, ensuring complete separation between the cutting waste and the aluminum profile. However, existing laser cutting devices suspend half of the aluminum profile in mid-air during laser cutting. After the laser cutting is complete, the suspended half of the aluminum profile falls onto the worktable, causing deformation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a laser cutting device for aluminum profile processing, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a laser cutting equipment for aluminum profile processing, including a base. A fixed seat is provided on the top of the base, and a fixing device is assembled on the top of the fixed seat. The fixing device includes a mounting seat fixedly installed on the top of the fixed seat. A connecting block is fixedly installed on the left side of the mounting seat. A T-shaped moving frame is slidably connected to the top of the connecting block. A lead screw is rotatably connected through the right side of the T-shaped moving frame. A connecting rod is fixedly installed on the left side of the mounting seat. A mounting plate is fixedly installed on the right side of the top of the connecting rod. A hydraulic chamber one is fixedly installed on the top of the mounting plate. A hydraulic rod one is slidably connected to a piston at one end of the hydraulic chamber one. A hydraulic rod two is slidably connected to a piston at the other end of the hydraulic chamber one. A fixing block one is fixedly installed at the bottom of the hydraulic rod two. A spring one is fixedly installed on the top of the fixing block one. A hydraulic chamber two is fixedly installed inside the mounting seat. A hydraulic rod three is slidably connected to a piston at one end of the hydraulic chamber two. A hydraulic rod four is slidably connected to a piston at the other end of the hydraulic chamber two. A fixing block two is fixedly installed on the top of the hydraulic rod four. A spring two is fixedly installed on the bottom of the fixing block two.

[0006] Preferably, the base has rails on both sides, a movable frame on the top of the rails, a lifting frame in the middle of the movable frame, a fixed column at the bottom of the lifting frame, a motor at the top of the fixed column, and a laser cutter on the front of the lifting frame.

[0007] Preferably, the right end of the lead screw is connected to the motor, and the first fixing block is located directly above the second fixing block.

[0008] Preferably, the interior of the mounting base is a hollow structure, and the top of the mounting base is provided with a circular through hole, through which the fixing block 2 passes.

[0009] Preferably, the top of the fixed column is equipped with a striking device for rotating and striking the aluminum profile.

[0010] Preferably, the striking device includes a rotating shaft connected to the output end of the motor and an L-shaped mounting bracket movably connected to the right side of the fixed column. A main gear is mounted on the right side of the rotating shaft. A movable shaft 1 is rotatably connected through the bottom of the L-shaped mounting bracket. A rolling wheel is mounted on the left side of the movable shaft 1, and a transmission gear 1 is mounted on the right side of the movable shaft 1. A movable shaft 2 is rotatably connected through the bottom of the L-shaped mounting bracket. A transmission gear 2 is mounted on the left side of the movable shaft 2, and a striking turntable is mounted on the right side of the movable shaft 2. A striking rod is provided on the outer side of the striking turntable.

[0011] Preferably, the L-shaped mounting bracket has a rack on the side facing the main gear, the rack meshes with the main gear, and the first transmission gear and the second transmission gear mesh with each other.

[0012] Preferably, the right side of the laser cutter is equipped with a grinding device for rotating and grinding aluminum profiles.

[0013] Preferably, the grinding device includes a mounting rod fixedly installed on the right side of the laser cutter, a pulley one mounted on the right side of the rotating shaft, a rotating rod rotatably connected through the bottom of the mounting rod, a pulley two mounted on the left side of the rotating rod, the pulley one and the pulley two being connected by belt drive, a grinding wheel mounted on the right side of the rotating rod, and a grinding layer mounted on the outer side of the grinding wheel.

[0014] Preferably, the polishing layer is made of rigid abrasive, and the outer contour of the polishing layer is adapted to the shape of the cut surface of the finished aluminum profile.

[0015] The advantages of this application are: (1) This application starts the motor to make the lead screw rotate. The rotation of the lead screw drives the T-shaped moving frame to move. When the T-shaped moving frame moves, it pushes the hydraulic rod one and the hydraulic rod three. The hydraulic rod one and the hydraulic rod three perform piston movement, causing the fixed block one to move downward and the fixed block two to move upward, thereby clamping the placed aluminum profile at the four corners. This avoids the aluminum profile falling off the worktable and causing deformation after laser cutting.

[0016] (2) This application sets up a striking device. The motor drives the rotating shaft to rotate, and the rotating shaft drives the main gear to rotate, thereby driving the L-shaped mounting bracket to move downward. The moving bracket moves on the track, driving the lifting bracket and the laser cutter to move. This causes the L-shaped mounting bracket to move, so that the rolling wheel contacts and rolls with the aluminum profile. At the same time, the transmission gear one and the transmission gear two mesh and drive the movable shaft two to rotate. The movable shaft two drives the striking turntable to rotate, and the striking rod on the striking turntable strikes the aluminum profile. This avoids the situation that often occurs in the laser cutting process, especially when the cutting thickness is large, the alloy composition is complex, or the cutting parameters are not optimal, after the cutting contour is completed, the part and the base material are not completely physically separated. The mechanical transmission replaces manual prying, avoiding the micro-deformation of the workpiece caused by external force impact. The striking force is precisely controlled by the gear ratio to ensure the separation effect without damaging the surface of the profile. The entire separation process is completed in parallel with the cutting process, shortening the single-piece processing time and significantly improving the continuous operation capability of the production line.

[0017] (3) The grinding device of this application is connected by the transmission of pulley one, belt and pulley two, so that the motor can drive the laser cutter to work and drive the grinding wheel to rotate. The grinding layer on the outside of the grinding wheel is made of rigid abrasive and the outer contour is adapted to the shape of the cut surface of the processed aluminum profile. It can accurately grind the cut surface of the aluminum profile, remove welding slag and molten slag, save the tedious process of manual hand-held grinding, reduce the labor burden of workers, reduce the risk of operation error, avoid the time loss and collision damage of the workpiece when transferring between different equipment, ensure the integrity of the product appearance, reduce the connection of production links, significantly shorten the processing cycle of a single product, save equipment purchase cost and production site occupation, and reduce equipment maintenance costs, thereby improving the overall production efficiency in many aspects.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-6As shown, a laser cutting equipment for aluminum profile processing includes a base 100, which, after treatment, can effectively absorb cutting vibrations and ensure the stability of the equipment during operation. Tracks 200 are provided on both sides of the base 100, and a movable frame 300 is provided on the top of the tracks 200. A lifting frame 600 is assembled in the middle of the movable frame 300, employing a double-guide column structure for lifting motion with high repeatability. A fixed column 500 is fixedly installed at the bottom of the lifting frame 600, and a motor 800 is provided on the top of the fixed column 500. A laser cutting blade is provided on the front of the lifting frame 600. 700, a fixed seat 400 is provided on the top of the base 100, and a fixing device 900 is assembled on the top of the fixed seat 400. The fixing device 900 includes a mounting seat 901 fixedly installed on the top of the fixed seat 400. A connecting block 902 is fixedly installed on the left side of the mounting seat 901. A T-shaped groove is machined on the top of the connecting block 902 to form a sliding pair with a T-shaped moving frame 903. The top of the connecting block 902 is slidably connected to the T-shaped moving frame 903. A lead screw 906 is rotatably connected through the right side of the T-shaped moving frame 903. The right end of the lead screw 906 is connected to the motor 80. A connecting rod 904 is fixedly installed on the left side of the mounting base 901. A mounting plate 905 is fixedly installed on the right side of the top of the connecting rod 904. The interior of the mounting base 901 has a hollow structure, and a circular through hole is provided at the top of the mounting base 901. A hydraulic chamber 907 is fixedly installed on the top of the mounting plate 905. A hydraulic rod 908 is slidably connected to one end of the hydraulic chamber 907 by a piston. A hydraulic rod 909 is slidably connected to the other end of the hydraulic chamber 907 by a piston. A fixing block 910 is fixedly installed at the bottom of the hydraulic rod 909. A spring 911 is fixedly installed on the top to provide buffer pressure and prevent workpiece damage. A hydraulic chamber 913 is fixedly installed inside the mounting base 901. A hydraulic rod 914 is slidably connected to a piston at one end of the hydraulic chamber 913. A hydraulic rod 915 is slidably connected to a piston at the other end of the hydraulic chamber 913. A fixing block 912 is fixedly installed on the top of the hydraulic rod 915. The fixing block 912 passes through a circular hole. A fixing block 910 is located directly above the fixing block 912. A spring 916 is fixedly installed on the bottom of the fixing block 912.

[0022] In practical use, the operator places the aluminum profile stably on the surface of the mounting base 901, then starts the motor 800 to drive the lead screw 906 to rotate. The lead screw 906 drives the T-shaped moving frame 903 to slide smoothly along the guide rail of the connecting block 902 through threaded transmission. During the movement, the T-shaped moving frame 903 pushes the hydraulic rod 1 908 and the hydraulic rod 3 914, causing the hydraulic rod 1 908 to generate piston movement in the hydraulic chamber 1 907. The thrust is transmitted to the hydraulic rod 2 909 through the hydraulic oil medium, causing the fixed block 1 909 to move vertically downward. At the same time, the hydraulic rod 3 914 performs piston movement synchronously in the hydraulic chamber 2 913, pushing the hydraulic rod 4 915 upward, causing the fixed block 2 912 to rise vertically. The two sets of fixed blocks form a "top and bottom clamping" four-corner clamping structure, which is buffered by the spring 1 911 and the spring 2 916. The clamping force is evenly applied to the four corners of the aluminum profile to achieve stress-free fastening. After fixing, the moving frame 300 moves precisely along the track 200, driving the lifting frame 600, the fixed column 500, and the laser cutter 700 to move as a whole to the cutting station. The lifting frame 600 adjusts its height through the servo system, so that the laser cutter 700 is precisely positioned on the cutting reference surface. During the cutting process, the fixing device continuously provides stable clamping to prevent deformation damage caused by the workpiece falling, and also facilitates the operator to quickly pick up and put down materials. This automated fixing mechanism significantly improves production safety and processing accuracy. The synchronous clamping at the four corners ensures that the aluminum profile does not warp or deform during the cutting process and ensures that the perpendicularity error of the cut is small. The hydraulic buffer design avoids the surface indentation of the profile caused by rigid clamping. The fixing process and the cutting process are seamlessly connected, the single-piece clamping time is shortened, and the efficiency of batch production is greatly improved.

[0023] Example 2, as Figures 1-8As shown, a laser cutting equipment for aluminum profile processing includes a striking device 1000 mounted on the top of a fixed column 500 for rotating and striking the aluminum profile. This device serves as a post-cutting processing unit and can eliminate residual stress on the cut surface of the aluminum profile through high-frequency mechanical striking. The striking device 1000 includes a rotating shaft 1001 connected to the output end of a motor 800 and an L-shaped mounting bracket 1003 movably connected to the right side of the fixed column 500. A main gear 1002 is mounted on the right side of the rotating shaft 1001, and a movable shaft 1005 rotatably passes through the bottom of the L-shaped mounting bracket 1003. A rolling wheel 1004 is mounted on the left side of the movable shaft 1005. The cam track on the right side of the fixed column 500 forms a guide support. The right side of the movable shaft 1005 is equipped with a transmission gear 1006. The L-shaped mounting bracket 1003 is provided with a rack on the side facing the main gear 1002. The rack meshes with the main gear 1002. The bottom of the L-shaped mounting bracket 1003 is connected to the movable shaft 2 1008 through and rotatably. The left side of the movable shaft 2 1008 is equipped with a transmission gear 2 1007. The transmission gear 1006 and the transmission gear 2 1007 mesh with each other. The right side of the movable shaft 2 1008 is equipped with a striking turntable 1009. A striking rod 1010 is provided on the outer side of the striking turntable 1009.

[0024] In practical use, the above-mentioned equipment is activated by starting the motor 800, which drives the rotating shaft 1001 to rotate. Through the meshing of the main gear 1002 and the rack of the L-shaped mounting bracket 1003, the mounting bracket is driven to move smoothly downwards. During this process, the moving frame 300 moves along the track 200 and simultaneously drives the lifting frame 600 and the laser cutter 700 to complete the cutting operation. After the L-shaped mounting bracket moves downwards, the rolling wheel 1004 at its bottom first contacts the surface of the aluminum profile and rolls with the cutting progress. At the same time, through the meshing of the first transmission gear 1006 and the second transmission gear 1007, the moving frame is driven to move downwards. The rotation of shaft 1008 and the striking turntable 1009 causes the striking rod 1010 on the turntable to precisely strike the incompletely separated parts, ultimately achieving complete separation of the part from the base material. This avoids workpiece deformation or surface damage that may be caused by manual prying with tools, ensuring the integrity of the product's appearance. Operators do not need to manually check the separation after cutting, reducing manual intervention costs and operational risks. The separation action is completed simultaneously with the cutting process, eliminating additional processing steps, shortening the processing cycle of a single product, ensuring consistent separation results for different batches of parts, and improving production stability.

[0025] Example 3, as Figures 1-10As shown, a laser cutting equipment for aluminum profile processing includes a grinding device 1100 for rotating and grinding aluminum profiles, mounted on the right side of a laser cutter 700. This device integrates power transmission and grinding functions, and can automatically start after the cutting process is completed, realizing integrated cutting and grinding operations. The grinding device 1100 includes a mounting rod 1104 fixedly installed on the right side of the laser cutter 700 and a pulley 1101 mounted on the right side of a rotating shaft 1001. The bottom of the mounting rod 1104 is rotatably connected to a... A rotating rod 1105 is equipped with a pulley 1102 on its left side. The pulleys 1101 and 1102 are connected by a belt 1103. A grinding wheel 1106 is equipped on the right side of the rotating rod 1105. A grinding layer 1107 is mounted on the outer side of the grinding wheel 1106. The grinding layer 1107, which is made of diamond rigid abrasive, is sintered on the outer side of the grinding wheel 1107 with a resin binder. The outer contour of the grinding layer 1107 is adapted to the shape of the cut section of the finished aluminum profile.

[0026] In practical use, when the laser cutter begins cutting, the motor 800 starts, driving the rotating shaft 1001 to rotate. The rotation of the rotating shaft 1001 drives the pulley 1101 to rotate, which, through the transmission of the belt 1103, drives the pulley 1102 to rotate, thereby driving the rotating rod 1105 and the grinding wheel 1106 to rotate smoothly. At this time, the rigid abrasive layer 1107 on the outer side of the grinding wheel 1106 will precisely fit the cut surface of the aluminum profile, and simultaneously grind the cut surface at the moment the cutting is completed, efficiently removing welding slag and molten slag. The mechanical transmission ensures the grinding force. The uniform and stable surface finish completely solves the problem of uneven surface roughness caused by uneven pressure when manually sanding with hand-held sandpaper. This ensures that the surface finish of each product is consistent, eliminating the need for manual transfer of workpieces between the cutting table and the sanding equipment. This avoids potential quality hazards such as surface scratches and edge bumps that may occur during handling. The entire processing flow is completed continuously at the same workstation without additional waiting or process switching. The processing cycle of a single product is shortened, reducing manual intervention and the labor intensity of operators. At the same time, it avoids production accidents caused by human error, significantly improving the safety and stability of workshop production.
