Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting device and processing technology for aluminum material blanking in the processing of sliding doors. Background Technology

[0002] In the production and processing of sliding doors, aluminum is the core structural material. In order to meet the overall strength and deformation resistance requirements of the doors and windows, its cross-section is often designed with longitudinal or transverse reinforcing ribs (such as T-shaped and L-shaped protrusion structures). At the same time, it is necessary to complete multiple processing steps such as 90° straight cutting and 45° oblique cutting and splicing. This places strict requirements on the cutting accuracy, surface flatness and integrity of the profile.

[0003] From the perspective of cutting method selection, although the existing single laser cutting can theoretically achieve fine cuts, its defects are particularly prominent when applied to aluminum alloy profiles with reinforcing ribs: the high reflectivity of aluminum alloys leads to low laser energy utilization, especially in the thick-walled parts of the reinforcing ribs. To ensure complete cut penetration, the exposure time needs to be significantly extended, which easily generates a large heat-affected zone, amplifies the difference in thermal expansion coefficients between the reinforcing ribs and the main profile, and causes local warping or micro-stress cracks.

[0004] Traditional sawing processes have lower equipment costs and are simpler, but existing equipment often lacks synchronous linkage and precise adjustment between the saw blade feed angle and the profile fixing mechanism. Especially during oblique cutting, the fixing mechanism fails to change its positioning direction synchronously with the saw blade angle adjustment, resulting in a non-ideal feed angle between the actual cutting line and the reinforcing rib. This can easily cause lateral polarization of the cutting saw, resulting in severe vibration at the root of the reinforcing rib and local high stress concentration, which can induce fatigue cracking at the connection between the reinforcing rib and the main body, or even directly cause chipping or burr formation at the cut edge. This significantly reduces the overall processing stability and production efficiency, making it difficult to support the quality and capacity requirements of modern industrialized mass production of sliding doors. Summary of the Invention

[0005] Given that existing technologies suffer from problems such as large heat-affected zones and easy warping and cracking due to the high reflectivity of aluminum alloy when laser cutting aluminum materials for sliding doors with reinforcing ribs, and the inability of the fixing mechanism to synchronously change the positioning direction with the saw blade angle adjustment in traditional sawing, resulting in large cutting vibration, low precision, and easy edge chipping, a laser cutting device and processing technology for aluminum material blanking in sliding door processing is proposed.

[0006] One aspect of this application provides a laser cutting device for aluminum material cutting in the processing of sliding doors. Its purpose is to solve the positioning and processing stability problems of straight and oblique cutting of aluminum material with reinforcing ribs by realizing the synchronous angle adjustment of the cutting saw and the reinforcing component, so as to meet the requirements of industrial mass production for cutting accuracy and profile integrity.

[0010] Furthermore, the reinforcing component also includes a folding cylinder disposed inside the support frame and communicating with the interior of the sealing cavity, with one end of the folding cylinder fixedly connected to the inner wall of the support frame and the other end of the folding cylinder fixedly connected to the outer wall of the sliding block, and the outer wall of the folding cylinder being provided with a flame-retardant insulating layer; the reinforcing component also includes a first connecting pipe disposed on the sleeve wall and communicating with the interior of the sealing cavity and an oil reservoir disposed on the top surface of the inner wall of the protective cover, with the end of the first connecting pipe and the end of the oil reservoir connected by an oil pipe; the reinforcing component also includes a second connecting pipe disposed on the sleeve wall and communicating with the interior of the sleeve, with the end of the second connecting pipe and the end of the oil reservoir connected by an oil pipe.

[0011] Furthermore, the reinforcing components also include an electrically controlled valve located at the end of the oil reservoir, and the inside of the electrically controlled valve, oil pipe, folding cylinder, sealing cavity and sleeve is filled with hydraulic oil. The amount of hydraulic oil inside the folding cylinder and sleeve can be fixed by the electrically controlled valve.

[0012] Furthermore, the reinforcing component also includes a first tapered channel opened inside the connecting block and a second tapered channel with damping holes disposed on the inner wall of the sleeve, wherein the second tapered channel is located between the second connecting tube and the compression spring.

[0013] Furthermore, the clamping mechanism includes a rotating seat rotatably disposed inside the control cabinet and a clamping roller slidably disposed on the rotating seat to clamp the aluminum material; a conveyor table is provided on the other side of the control cabinet, a pushing mechanism for pushing the aluminum material is provided on the conveyor table, and a support roller for supporting the aluminum material is also provided on the conveyor table; a guide plate is provided on the top surface of the cutting box, a collection box is provided at the bottom of the cutting box, and the side of the lifting cabinet near the collection box is inclined.

[0014] Furthermore, the lifting cabinet is equipped with a lifting rotary cylinder, and the movable end of the lifting rotary cylinder is connected to the base of the cutting saw. The rotation angle of the movable end of the lifting rotary cylinder is the same as the rotation angle of the stepper motor output shaft.

The top of the lifting cabinet is equipped with an electric multi-stage telescopic rod, and the movable end of the electric multi-stage telescopic rod is fixedly connected to the outer wall of the push plate.

Step 5: After cutting, the push plate on the top of the lifting cabinet pushes out the cut aluminum material. The cut aluminum material slides down the inclined side of the lifting cabinet to the bottom collection box via the guide plate on the top of the cutting box.

[0016] The beneficial effects of this invention are:

[0017] 1. This device addresses the issues of deformation, displacement, and stress concentration that easily occur during the cutting of reinforced aluminum profiles. It features a multi-directional adaptive clamping and positioning reinforcement structure. Two sets of reinforcement components provide constraints on both sides of the cutting saw, offering multi-point clamping and synchronous rotation according to the cutting angle. This ensures the aluminum profile remains stable in critical cutting areas, whether cutting straight or at an angle. The first positioning cylinder, second positioning cylinder, tension spring, compression spring, and hydraulic mechanism work together to not only conform to aluminum profiles of various cross-sections but also buffer and absorb vibrations during cutting, significantly improving cutting accuracy and surface flatness. Simultaneously, it greatly reduces the risk of micro-cracks at the root of the reinforcement ribs, increasing product yield.

[0018] 2. This device integrates multiple functions such as clamping, positioning, laser / sawing, unloading, and material collection. Each mechanism is linked by electrical control to achieve parameterized linkage, improving automation and processing efficiency. The height and angle of the lifting cabinet, cutting saw, and laser cutting head are linked, enabling aluminum materials to be cut and drilled at different angles and processes in the same workstation. The integrated design of the automatic pusher plate and material collection box simplifies the unloading and waste collection process, reduces manual intervention, and improves assembly line efficiency and process continuity.

[0019] 3. This device controls the opening of the hydraulic circuit before cutting, allowing the first and second positioning cylinders to adapt to aluminum materials of different sizes and shapes, reducing adjustment difficulty. During cutting, the hydraulic circuit is closed to achieve rigid locking, minimizing clamping loosening caused by vibration, impact, and cutting forces. The hydraulic buffer and tapered channel design effectively absorbs minor vibrations, significantly reducing the risk of damage to reinforced aluminum materials caused by concentrated force during cutting.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Example 1, referring to Figures 1-10 The first embodiment of the present invention provides: a laser cutting device for aluminum material cutting in the processing of sliding doors, including a control cabinet 1, a clamping mechanism 2 for clamping aluminum material disposed on the control cabinet 1, and a laser cutting mechanism 3 disposed on the control cabinet 1. A cutting box 9 is disposed on one side of the control cabinet 1. A lifting cabinet 10 is slidably installed inside the cutting box 9. A cutting saw 11 is slidably installed inside the lifting cabinet 10. A plurality of through slots 12 for the cutting saw 11 to pass through are opened on the top surface of the lifting cabinet 10. A protective cover 13 is slidably installed on the top surface of the cutting box 9. A reinforcing component 14 for positioning the aluminum material is disposed inside the protective cover 13. A push plate 38 is slidably installed on the top surface of the lifting cabinet 10.

[0034] The reinforcing component 14 includes a clamping rod 15 disposed on the side of the aluminum material, a first positioning cylinder 16 rotatably mounted on the wall of the clamping rod 15, an I-shaped rod 23 disposed on the top of the aluminum material, and a second positioning cylinder 24 rotatably mounted on the wall of the I-shaped rod 23. The reinforcing component 14 is provided in two sets, and each set of the reinforcing component 14 has two clamping rods 15. The two first positioning cylinders 16 corresponding to the clamping rods 15 clamp the front and rear sides of the aluminum material respectively, and the clamping direction of the two first positioning cylinders 16 is always parallel to the angle of the cutting saw 11.

[0035] Specifically, the laser cutting mechanism 3 includes a laser cutting head, which can perform grooving and hole-making processes on the surface of aluminum. Different through slots 12 represent different bevel angles, and the protective cover 13 can prevent waste from splashing and injuring operators during the cutting process. After cutting, the cut aluminum material can be pushed down the lifting cabinet 10 by the push plate 38. The cutting saw 11 can rise from the inside of the lifting cabinet 10 and pass through the through slots 12 to cut the aluminum material on the lifting cabinet 10. At the same time, the cutting saw 11 can also descend into the lifting cabinet 10 and then rotate to adjust its cutting angle.

[0036] Two sets of reinforcing components 14 form constraints on the left and right sides of the cutting saw 11, respectively. Two clamping rods 15, in conjunction with the first positioning cylinder 16, clamp the aluminum material on both the front and rear sides, while the I-shaped rod 23, in conjunction with the second positioning cylinder 24, limits the top of the aluminum material. This multi-directional restriction restricts the displacement and warping of the aluminum material. When the angle of the cutting saw 11 changes, the two sets of reinforcing components 14 remain close to the left and right sides of the cutting saw 11 while clamping the aluminum material. This helps to form a stable near-cut constraint around the cutting area, reducing vibration and deformation of the aluminum material during cutting, thereby ensuring cutting accuracy and the integrity of the aluminum material.

[0037] It is important to note that the aluminum material of sliding doors often has reinforcing ribs. The presence of these ribs makes the aluminum material more prone to localized stress concentration during cutting, especially during bevel cuts. Changes in the direction of the cutting force amplify this problem, increasing the risk of vibration and displacement of the aluminum material during the cutting process. By synchronizing the angle changes, it is ensured that the clamping direction of the first positioning cylinder 16 and the pressing direction of the second positioning cylinder 24 in each set of reinforcing components 14 are always parallel to the angle of the cutting saw 11. This allows for better contact with the surface of the aluminum material with reinforcing ribs, providing uniform clamping and support forces. This effectively avoids torsion or bending deformation of the aluminum material due to mismatched cutting angles, reduces the breakage rate during the cutting process, and improves the quality of the finished product.

[0038] Reference Figures 3-7The top of the two sets of reinforcing components 14 is provided with a connecting plate 32. A rotating shaft 33 is fixedly installed on the top surface of the connecting plate 32, and the top end of the rotating shaft 33 is rotatably connected to the top surface of the inner wall of the protective cover 13. A stepper motor 37 is fixedly installed on the top surface of the protective cover 13, and the output shaft of the stepper motor 37 is fixedly connected to the top end of the rotating shaft 33.

[0039] Specifically, the stepper motor 37 drives the connecting plate 32 through the rotating shaft 33 to drive the two sets of reinforcing components 14 to rotate synchronously, ensuring that when the angle of the cutting saw 11 is adjusted, the clamping angle of the reinforcing component 14 is completely matched with that of the cutting saw 11, avoiding clamping failure caused by angle misalignment in traditional fixed positioning structures, and is especially suitable for the processing requirements of beveled angles of aluminum materials with reinforcing ribs.

[0040] Reference Figures 4-8 The reinforcing component 14 also includes a sliding block 17 fixedly installed on the top of the clamping rod 15, a bearing frame 18 sleeved on the outer wall of the sliding block 17, and a tension spring 19 disposed inside the bearing frame 18. One end of the tension spring 19 is fixedly connected to the outer wall of the sliding block 17, and the other end of the tension spring 19 is fixedly connected to the inner wall of the bearing frame 18. The reinforcing component 14 also includes a sleeve 20 sleeved on the top of the I-shaped rod 23, a sealing cavity 21 opened on the top of the sleeve 20, and a connecting block 22 fixedly installed inside the sealing cavity 21. The end of the connecting block 22 away from the sealing cavity 21 is fixedly connected to the outer wall of the bearing frame 18, and the top surface of the sleeve 20 is fixedly connected to the bottom surface of the connecting plate 32. The reinforcing component 14 also includes a compression spring 25 disposed inside the sleeve 20, and the compression spring 25 is located at the top of the I-shaped rod 23.

[0041] Specifically, the tension spring 19 drives the clamping rod 15 to adapt to the width change of the aluminum material through the sliding block 17, and the compression spring 25 can push the I-shaped rod 23 to drive the second positioning cylinder 24 to adapt to the thickness of the aluminum material.

[0042] Reference Figures 1-4 The clamping mechanism 2 includes a rotating seat 4 rotatably installed inside the control cabinet 1 and a clamping roller 5 slidably installed on the rotating seat 4 to clamp the aluminum material; a conveyor 6 is provided on the other side of the control cabinet 1, a pushing mechanism 7 for pushing the aluminum material is provided on the conveyor 6, and a support roller 8 for supporting the aluminum material is also provided on the conveyor 6; a guide plate 42 is fixedly installed on the top surface of the cutting box 9, a collection box 34 is provided at the bottom of the cutting box 9, and the side of the lifting cabinet 10 close to the collection box 34 is inclined.

[0043] Specifically, the rotating seat 4 and clamping roller 5 in the clamping mechanism 2 can rotate synchronously with the aluminum material feed, reducing frictional damage between the clamping surface and the aluminum material. The support roller 8 of the conveyor table 6 can support long aluminum materials, avoiding positioning deviations caused by bending due to its own weight. The pushing mechanism 7 realizes automatic feeding of aluminum materials, reducing manual labor intensity. The guide plate 42 on the top surface of the cutting box 9 cooperates with the inclined surface of the lifting cabinet 10 to guide the cut aluminum material or waste material to slide smoothly into the collection box 34, realizing integrated cutting and collection, eliminating the need for manual cleaning, reducing process intervals, and improving batch production efficiency.

[0044] Reference Figure 9 The lifting cabinet 10 is equipped with a lifting rotary cylinder 40, and the movable end of the lifting rotary cylinder 40 is connected to the base of the cutting saw 11. The rotation angle of the movable end of the lifting rotary cylinder 40 is the same as the rotation angle of the output shaft of the stepper motor 37. The bottom of the cutting box 9 is equipped with a lifting platform 41, and the movable end of the lifting platform 41 is connected to the bottom surface of the lifting cabinet 10. The top of the lifting cabinet 10 is fixedly installed with an electric multi-stage telescopic rod 39, and the movable end of the electric multi-stage telescopic rod 39 is fixedly connected to the outer wall of the push plate 38.

[0045] Specifically, the rotation angle of the lifting rotary cylinder 40 is kept consistent with that of the stepper motor 37, ensuring that the angle of the cutting saw 11 and the reinforcing component 14 are perfectly matched, thus solving the problem of positioning failure after the saw blade angle is adjusted in traditional equipment.

[0046] The lifting platform 41 is adjustable in height to accommodate the cutting depth requirements of aluminum materials of different thicknesses, improving the equipment's versatility. Furthermore, when the laser cutting mechanism 3 is operating, the lifting platform 41 lowers the lifting cabinet 10, providing rotation space for the aluminum material and facilitating grooving and drilling on various surfaces of the aluminum. The electric multi-stage telescopic rod 39 drives the push plate 38 to precisely control the ejection of the cut aluminum material from the top of the lifting cabinet 10. The parameterized control angles, heights, and feed rates of each component can be uniformly set through the control cabinet 1, ensuring that the processing dimensions and cutting angles of each batch of aluminum material are completely consistent, meeting the needs of industrial mass production.

[0047] Example 2, refer to Figures 3-8This is the second embodiment of the present invention, which differs from the first embodiment in that: the reinforcing component 14 further includes a folding cylinder 26 fixedly installed inside the support frame 18 and communicating with the interior of the sealing cavity 21. One end of the folding cylinder 26 is fixedly connected to the inner wall of the support frame 18, and the other end of the folding cylinder 26 is fixedly connected to the outer wall of the sliding block 17. The outer wall of the folding cylinder 26 is provided with a flame-retardant insulating layer. The reinforcing component 14 also includes a first connecting pipe 27 fixedly installed on the wall of the sleeve 20 and communicating with the interior of the sealing cavity 21, and an oil reservoir 30 fixedly installed on the top surface of the inner wall of the protective cover 13. The end of the first connecting pipe 27 and the end of the oil reservoir 30 are connected by an oil pipe 29. The reinforcing component 14 also includes a second connecting pipe 28 fixedly installed on the wall of the sleeve 20 and communicating with the interior of the sleeve 20. The end of the second connecting pipe 28 and the end of the oil reservoir 30 are connected by an oil pipe 29.

[0048] Specifically, the folding cylinder 26, the sealing cavity 21, the first connecting pipe 27, the second connecting pipe 28, the sleeve 20, and the oil reservoir 30 work together to form a closed hydraulic space to prevent hydraulic oil leakage. The flame-retardant insulation layer on the outer wall of the folding cylinder 26 can isolate the high temperature and sparks generated during cutting, prevent the hydraulic oil from being affected by high temperature and deteriorating, and at the same time protect the folding cylinder 26 from damage by high temperature and sparks, thus extending the service life of the components.

[0049] Reference Figure 7 The reinforcing component 14 also includes an electrically controlled valve 31 located at the end of the oil reservoir 30. The electrically controlled valve 31, the oil pipe 29, the folding cylinder 26, the sealing cavity 21 and the sleeve 20 are filled with hydraulic oil. The amount of hydraulic oil inside the folding cylinder 26 and the sleeve 20 can be fixed by the electrically controlled valve 31.

[0050] Specifically, by controlling the on / off state of the electronically controlled valve 31, the valve opens, allowing hydraulic oil to flow to adapt to aluminum materials of different sizes; when the valve closes, the hydraulic oil is fixed, adapting to the needs of different processes such as aluminum material feeding, positioning, and cutting, without the need for manual adjustment of the mechanical structure, thus improving processing efficiency.

[0051] During the cutting operation, closing the electric control valve 31 can fix the hydraulic oil volume in the folding cylinder 26 and the sleeve 20, so that the position and clamping force of the clamping rod 15, the first positioning cylinder 16 and the second positioning cylinder 24 remain constant, avoiding positioning loosening caused by the vibration of the cutting saw 11. It is especially suitable for lateral force constraint when cutting at 45° angle, and prevents torsional deformation of aluminum material with reinforcing ribs.

[0052] Reference Figure 8 The reinforcing component 14 also includes a first tapered channel 35 opened inside the connecting block 22 and a second tapered channel 36 with damping holes fixedly installed on the inner wall of the sleeve 20, and the second tapered channel 36 is located between the second connecting pipe 28 and the compression spring 25.

[0053] Specifically, during the cutting process, the vibration of the cutting saw 11 is transmitted to the first positioning cylinder 16 and the second positioning cylinder 24 through the aluminum material. When the hydraulic oil flows in the first tapering channel 35 and the second tapering channel 36, it generates viscous resistance, which can absorb some of the vibration energy, reduce the impact of vibration on the aluminum material, reduce the micro-stress cracks at the connection between the reinforcing rib and the main aluminum material, and ensure the smoothness of the cut.

[0054] The remaining structure is the same as that in Example 1.

[0055] Working principle: First, the aluminum material with reinforcing ribs to be processed is placed on the conveyor table 6. The support rollers 8 of the conveyor table 6 provide stable support for the aluminum material, preventing long aluminum materials from bending due to their own weight. The pushing mechanism 7 is activated to push the aluminum material towards the control cabinet 1. When one end of the aluminum material enters the clamping mechanism 2 of the control cabinet 1, the clamping rollers 5 of the clamping mechanism 2, in cooperation with the rotating seat 4, initially clamp the aluminum material. The rotating seat 4 can rotate synchronously with the aluminum material as it is fed, greatly reducing frictional damage between the clamping rollers 5 and the surface of the aluminum material, ensuring that the aluminum material is smoothly transported to the top surface of the lifting cabinet 10 of the cutting box 9.

[0056] One end of the aluminum material contacts the arc surface of the first positioning cylinder 16 and the arc surface of the second positioning cylinder 24, causing the two first positioning cylinders 16 inside the two sets of reinforcing components 14 to move away from each other, and causing the second positioning cylinder 24 to rise until the first positioning cylinder 16 and the second positioning cylinder 24 stably clamp the surface of the aluminum material. It should be noted that since the first positioning cylinder 16 and the second positioning cylinder 24 are in rolling contact with the surface of the aluminum material, it does not affect the position of the protective cover 13 that the workers can move.

[0057] The stepper motor 37 on the top surface of the protective cover 13 drives the rotating shaft 33 to rotate, which in turn drives the connecting plate 32 and the two sets of reinforcing components 14 at the bottom to rotate synchronously, so that the angle of the reinforcing component 14 is consistent with the preset angle (straight cut or oblique cut) of the cutting saw 11. At this time, the tension spring 19 in the bearing frame 18 pulls the clamping rod 15 through the sliding block 17, so that the two first positioning cylinders 16 are close to the front and rear sides of the aluminum material to form a horizontal clamping. At the same time, the compression spring 25 in the sleeve 20 pushes the I-shaped rod 23, so that the second positioning cylinder 24 presses against the top surface of the aluminum material to achieve vertical limitation, forming a stable clamping near the cut on the left and right sides of the cutting saw 11, which is suitable for complex cross sections of aluminum materials with reinforcing ribs.

[0058] The oil reservoir 30, together with the folding cylinder 26, sealing cavity 21, and sleeve 20, forms a closed hydraulic space via the oil pipe 29, the first connecting pipe 27, the second connecting pipe 28, the oil pipe 29, the first connecting pipe 27, the second connecting pipe 28, the sleeve 20, and the oil reservoir 30. When adjusting the position of the first positioning cylinder 16 and the second positioning cylinder 24, the electric control valve 31 is opened, and the hydraulic oil can flow in each chamber. With the help of the tension spring 19 and the compression spring 25, the self-adaptive ability of the first positioning cylinder 16 and the second positioning cylinder 24 is further enhanced. Before cutting, the electric control valve 31 is closed to fix the hydraulic oil volume and lock the clamping position and force. At the same time, the first tapering channel 35 of the connecting block 22 and the second tapering channel 36 of the sleeve 20 limit the flow speed of the hydraulic oil through the damping orifice. This not only avoids the impact vibration when the positioning cylinder is in contact with the aluminum material, but also absorbs the vibration energy during the cutting process and prevents stress concentration cracking at the root of the reinforcing rib.

[0059] If grooving or drilling is required, the lifting platform 41 lowers the lifting cabinet 10 to provide rotation space for the aluminum material. The laser cutting mechanism 3 on the control cabinet 1 precisely processes the surface of the aluminum material through the laser cutting head. If cutting is required, the lifting rotary cylinder 40 drives the cutting saw 11 to rotate to a set angle (completely synchronized with the rotation angle of the stepper motor 37 to ensure that the cutting direction is parallel to the clamping direction of the reinforcing component 14). At the same time, the lifting platform 41 adjusts the height of the lifting cabinet 10 so that the cutting saw 11 extends from the through slot 12 on the top surface of the lifting cabinet 10 to cut the aluminum material straight or obliquely. During the cutting process, the reinforcing component 14 always forms a constraint around the cut, effectively suppressing the torsional deformation of the aluminum material caused by the lateral force of the cutting saw 11.

[0060] After cutting, the electric multi-stage telescopic rod 39 drives the push plate 38 to push the cut aluminum material out from the top of the lifting cabinet 10. The aluminum material slides down the inclined side of the lifting cabinet 10 to the bottom collection box 34 via the guide plate 42 on the top of the cutting box 9, achieving automatic material collection. Throughout the process, the control cabinet 1 uniformly sets parameters such as pushing amount, cutting angle, and clamping force. Through the synchronous control of the stepper motor 37 and the lifting rotary cylinder 40, and the coordinated constraint of the hydraulic system and the elastic structure, the automation, high precision, and stability of the processing of aluminum material with reinforcing ribs are achieved.

[0061] Example 3, referring to Figures 1-10 The fourth embodiment of the present invention provides a laser cutting process for aluminum material blanking in sliding door processing, employing a laser cutting device for aluminum material blanking in sliding door processing, comprising the following steps:

[0062] Step 1: Place the aluminum material to be processed on the support roller 8 of the conveyor table 6, and then connect the other end of the aluminum material to the pushing mechanism 7. Start the pushing mechanism 7 to push the aluminum material into the control cabinet 1. When one end of the aluminum material enters the clamping mechanism 2, the rotating seat 4 drives the clamping roller 5 to roll and clamp the aluminum material, and smoothly transport it to the top surface of the lifting cabinet 10 of the cutting box 9.

[0063] Step 2: The two sets of reinforcing components 14 inside the protective cover 13 are activated. The two clamping rods 15 of each set of reinforcing components 14 clamp the aluminum material from the front and rear sides through the first positioning cylinder 16. The I-shaped rod 23 is limited from the top of the aluminum material through the second positioning cylinder 24. The clamping direction of the two first positioning cylinders 16 of each set of reinforcing components 14 is parallel to the angle of the cutting saw 11, forming a stable constraint.

[0064] Step 3: Control the lifting cabinet 10 to descend, leaving room for the aluminum material to rotate. The laser cutting mechanism 3 on the control cabinet 1 performs precise grooving and hole cutting on the surface of the aluminum material through the laser cutting head.

[0065] Step 4: When the lifting cabinet 10 is raised again and the angle of the cutting saw 11 needs to be adjusted, ensure that the clamping direction of the cutting saw 11 matches that of the first positioning cylinder 16, and then raise the cutting saw 11 from inside the lifting cabinet 10 and extend it from inside the corresponding through slot 12 to cut the aluminum material.

[0066] Step 5: After cutting, the push plate 38 on the top surface of the lifting cabinet 10 pushes out the cut aluminum material. The cut aluminum material slides down the inclined side of the lifting cabinet 10 to the bottom collection box 34 via the guide plate 42 on the top surface of the cutting box 9.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
