Description

Technical Field

[0001] This invention relates to the field of profile processing, and in particular to a profile sawing device, a profile processing system and its working method. Background Technology

[0002] The end face structure of curtain wall profiles is a key part to ensure that they fit tightly with connectors, adjacent profiles or building structures. The end face structure is complex, including tenons, bolt holes, cuts, bevels, etc., and is used for bolt fixing, rubber strip installation or drainage design. Compared with ordinary door and window profiles, it has the characteristics of large cross-sectional area and heavy weight.

[0003] Related technologies provide a multi-host sawing and milling processing unit, processing center, and working method for curtain wall profiles. The unit includes at least two sets of sawing and milling fixtures arranged in parallel. A first sawing and milling processing mechanism and a second sawing and milling processing mechanism are located in the area between the two sets of fixtures. The first sawing and milling processing mechanism has a lateral sawing and milling host located in the lateral space of the profile to be processed, and the lateral sawing and milling host rotates around the y-axis. The second sawing and milling processing mechanism has a vertical sawing and milling host located in the upper space of the profile to be processed, and the vertical sawing and milling host rotates around both the z-axis and the y-axis. This technical solution enables the curtain wall profile to complete the required sawing and milling processing in a single clamping operation, reducing the number of repeated clamping operations and improving processing accuracy and efficiency.

[0004] However, in the above technical solutions, the side milling machine is installed on the corresponding base and slide plate, while the vertical milling machine is suspended on the gantry truss. The two rely on different guide rails, lead screws and drive motors, which makes their mechanical zero points, thermal deformation and wear characteristics different. When co-processing the end of the same profile, the cumulative positioning errors of the two sets of motion chains accumulate with each other, resulting in a large processing error. At the same time, the dual processing machines need to be arranged in a large independent motion space, which increases the width of the whole machine and makes the equipment occupy a large area, making it difficult to adapt to compact production lines. Summary of the Invention

[0005] To address the technical problems of large processing errors and large space occupation in the existing curtain wall profile processing devices, the present invention provides a profile sawing device, a profile processing system and its working method, which can improve processing accuracy and reduce the space occupation of the sawing device.

[0006] In a first aspect, the present invention provides a profile sawing device to solve the above-mentioned technical problems, comprising a sawing base, and further comprising: a movable column, the movable column being movably disposed on the base along the X direction; a lifting slide, the lifting slide being movably disposed on the movable column along the Z direction; a swing arm, the swing arm extending along the Y direction in its length direction, one end of the swing arm being rotatably disposed on the lifting slide; and a sawing assembly, the sawing assembly being rotatably disposed at the other end of the swing arm, the sawing assembly comprising a saw blade.

[0007] This invention achieves multi-position, multi-angle sawing of profiles with only one sawing actuator by using a moving column, lifting slide, swing arm and sawing components in a multi-degree-of-freedom manner. This reduces the number of independent moving parts, reduces the accumulation of errors in multiple motion chains, ensures processing accuracy, and reduces the space occupied by the equipment.

[0008] Furthermore, it also includes a sawing clamping assembly one and a sawing clamping assembly two. The sawing clamping assembly one includes a fixed clamping base, which is disposed at the sawing feed end. The sawing clamping assembly two includes a movable clamping base, which is movable along the X direction to be disposed at the sawing discharge end. A discharge component is movable along the X direction on the movable clamping base.

[0009] This invention, by setting a second sawing clamping component that can move along the X direction, can achieve material receiving during sawing and feeding. On the one hand, it provides far-end rigid support for long profiles to eliminate the hanging and deflection deformation caused by the profile's own weight, thereby ensuring the perpendicularity and length accuracy of the saw cut surface. On the other hand, it fixes both ends of the profile during sawing, enhances the system rigidity, and ensures the stability of large feed cutting.

[0010] Furthermore, both the first sawing clamping assembly and the second sawing clamping assembly include a first vertical clamping unit, a second vertical clamping unit, and a second horizontal clamping unit. The first vertical clamping unit includes a first pressure plate, and the second vertical clamping unit includes a second pressure plate. The first and second pressure plates are both vertically mounted on the fixed clamping base or the movable clamping base. The second horizontal clamping unit includes a horizontal clamping block, which can move along a direction that forms a certain angle with the X-axis. The two horizontal clamping blocks are arranged in a figure-eight pattern on both sides of the sawing assembly. The fixed clamping base and the movable clamping base are both vertically mounted with positioning plates, which are positioned opposite to the horizontal clamping blocks.

[0011] This invention uses a combination of vertical and horizontal clamping units with a figure-eight-shaped horizontal clamping block to constrain the profile from multiple directions, effectively suppressing displacement and torsion during the sawing process and improving clamping stability and processing accuracy.

[0012] Furthermore, both the fixed clamping base and / or the movable clamping base are provided with auxiliary support plates that are movable along the X direction, and the auxiliary support plates are provided with the vertical pressing unit and the positioning plate.

[0013] This invention effectively supports the ends of the profile by using a movable auxiliary support plate, avoiding poor support strength caused by a long distance protruding from the fixed or movable clamping base during inclined sawing, thus ensuring the perpendicularity and length accuracy of the saw cut surface.

[0014] Furthermore, the auxiliary support plate is slidably disposed on the fixed clamping base and / or the movable clamping base, and the auxiliary support plate is connected to an auxiliary motor through a transmission mechanism, wherein the auxiliary motor is a servo motor.

[0015] This invention uses a servo motor to drive the auxiliary support plate to move, which can accurately determine the extension distance of the auxiliary support plate according to the requirements, ensuring sufficient support strength, while avoiding interference with the saw blade.

[0016] Furthermore, the discharge assembly includes a support slide, which is disposed at the discharge end of the movable clamping base. A discharge slide is movably disposed on the support slide along the X direction. A fixed clamp is disposed on the end of the discharge slide near the positioning plate. A movable clamp is also movably disposed on the discharge slide along the Y direction. The movable clamp is disposed opposite to the fixed clamp and can move towards and away from the fixed clamp.

[0017] Furthermore, the feeding end of the fixed clamping base is vertically provided with a clamping bracket, and an upper clamping roller is rotatably provided on the clamping bracket. The feeding end of the fixed clamping base is rotatably provided with a lower clamping roller. The upper clamping roller and the lower clamping roller are arranged opposite to each other. The feeding end of the fixed clamping base is also vertically provided with a fixed roller. The clamping bracket is vertically and movably provided with a movable roller, which can move closer to and further away from the fixed roller.

[0018] This invention combines an upper clamping roller, a lower clamping roller, a movable roller, and a fixed roller to form multi-point constraints at the sawing feed end, adapting to the conveying of profiles with different cross-sectional shapes, reducing offset and slippage during the feeding process, and improving conveying stability.

[0019] Secondly, the present invention also provides a profile processing system, which further includes a feeding device and a drilling-milling composite processing device. The feeding device is disposed at the feeding end of the drilling-milling composite processing device. The drilling-milling composite processing device includes a drilling-milling base and the aforementioned profile sawing device. The drilling-milling base is located at the feeding end of the sawing base. A gantry frame is disposed on the drilling-milling base. The gantry frame includes two opposing support columns. A crossbeam is connected to the upper ends of the two support columns. A movable seat is movably disposed on the sawing base along the X direction. Drilling-milling processing components are disposed on the movable seat, the crossbeam, and the two support columns. The four drilling-milling processing components are respectively used to process different surfaces of the profile. A drilling-milling clamping component is also disposed on the top of the movable seat.

[0020] This invention, by setting a movable seat, can provide feeding assistance when the feeding device is feeding material, and provide active driving force at the front end of the profile. This solves the problem of insufficient driving force when conveying heavy long profiles over long distances, avoids the long profiles from shifting or twisting during long-distance conveying, reduces the reaction force of the profiles on the feeding device, and greatly reduces the wear of related components of the feeding device. At the same time, the movable seat can realize the material flow from drilling and milling to sawing during tail material processing.

[0021] Thirdly, the present invention also provides a method for operating a profile processing system. When processing curtain wall profiles using the aforementioned profile processing system, the method includes the following steps: S01: The feeding device feeds the curtain wall profile into the upper part of the moving seat along the X direction, and the curtain wall profile is clamped by the drilling and milling clamping assembly and then moved along the X direction; S02: Start the corresponding drilling and milling processing components to perform drilling and milling processing on the upper surface, two side surfaces and the lower surface of the curtain wall profile respectively; S03: After drilling and milling, the feeding device feeds the curtain wall profile into the sawing feed end. If it is the sawing of the tail section, the moving seat needs to clamp the curtain wall profile. The profile sawing device is close to the feeding device, so that the moving clamping base moves to the set position in the direction of the fixed clamping base, so that the curtain wall profile passes through the sawing clamping assembly one and extends to the top of the moving clamping base of the sawing clamping assembly two. At the same time, when it is determined that the end of the curtain wall profile needs to be sawed at an angle, the auxiliary support plate extends in the direction of the sawing assembly. S04: After the vertical clamping unit one and / or the vertical clamping unit two and the horizontal clamping unit of the sawing clamping assembly two clamp the curtain wall profile to the corresponding positioning plate, the movable clamping base moves to a set position away from the fixed clamping base to leave clearance space for sawing. S05: The vertical clamping unit one and / or the vertical clamping unit two and the horizontal clamping unit of the sawing clamping assembly one press the curtain wall profile against the corresponding positioning plate; S06: Drive the movable column to move along the X direction to the sawing position, drive the lifting slide to move along the Z direction to the sawing height, and drive the swing arm and the sawing assembly to rotate, so that the saw blade rotates to the corresponding sawing angle; S07: Start the sawing assembly to perform sawing. During the sawing process, the discharge assembly keeps the curtain wall profile clamped. At the same time, if there are drilling and milling operations on the curtain wall profile that do not require X-axis movement, the corresponding drilling and milling assembly performs drilling and milling operations on the curtain wall profile. S08: After sawing is completed, the vertical clamping unit one and / or the vertical clamping unit two and the horizontal clamping unit are released, and the discharge assembly removes the cut curtain wall profile.

[0022] This invention ensures accurate initial positioning and stable conveying of curtain wall profiles through a movable receiving seat. The second sawing clamping component actively approaches and presses the material, effectively preventing the large-section heavy profiles from sagging and swaying under their own weight in a long overhang state. On this basis, for inclined sawing, an auxiliary support plate extends to fill the support blind spot and eliminate local deflection deformation. The continuous clamping of the discharge component throughout the sawing process firmly suppresses the impact vibration and displacement at the moment of cutting. The above links together construct a full-stroke, high-rigidity constraint system for curtain wall profiles, eliminating loosening, deformation and secondary positioning errors in processing from the root, and significantly improving the verticality, flatness and relative position accuracy between the hole system and the end face of the curtain wall profile sawing end face.

[0023] Furthermore, when processing door and window profiles, the following steps are included: T01: The feeding device feeds the door and window profiles into the upper part of the moving seat along the X direction, and the door and window profiles are clamped by the drilling and milling clamping assembly and then moved along the X direction; T02: Start the corresponding drilling and milling processing components to perform drilling and milling processing on the upper surface, two side surfaces and the lower surface of the door and window profiles respectively; T03: After drilling and milling, the feeding device feeds the door and window profile into the sawing feed end. If it is the sawing of the tail section, the moving seat needs to clamp the door and window profile. The profile sawing device is close to the feeding device, so that the moving clamping base moves to the set position in the direction of the fixed clamping base, so that the door and window profile passes through the sawing clamping assembly one and extends to the moving clamping base of the sawing clamping assembly two. At the same time, when it is determined that the end of the door and window profile needs to be sawed at an angle, the auxiliary support plate extends in the direction of the sawing assembly. T04: After the vertical clamping unit one and the horizontal clamping unit of the sawing clamping assembly two clamp the door and window profiles to the corresponding positioning plates, the movable clamping base moves to a set position away from the fixed clamping base to leave clearance space for sawing. T05: The vertical clamping unit and the horizontal clamping unit of the sawing clamping assembly one press the door and window profiles against the corresponding positioning plates; T06: Drive the movable column to move along the X direction to the sawing position, drive the lifting slide to move along the Z direction to the sawing height, and drive the swing arm and the sawing assembly to rotate, so that the saw blade rotates to the corresponding sawing angle; T07: Start the sawing assembly to perform sawing. During the sawing process, the discharge assembly keeps clamping the door and window profile. At the same time, if there are drilling and milling operations on the door and window profile that do not require X-axis movement, the corresponding drilling and milling assembly performs drilling and milling operations on the door and window profile. T08: After sawing is completed, the vertical clamping unit and the horizontal clamping unit are released, and the discharge assembly removes the cut door and window profiles.

[0024] This invention utilizes a movable base and a second sawing clamping component to receive the material, while the output component clamps the material throughout the sawing process. This effectively suppresses shaking and cutting impact during the sawing of small-section profiles, ensuring flatness of the end face and dimensional accuracy. Combined with the auxiliary support plate extending as needed during inclined sawing, it guarantees processing accuracy. It enables multi-surface drilling and milling and multi-angle sawing to be completed in a single clamping setup, and supports parallel processing of non-X-axis moving drilling and milling operations. This significantly reduces process switching and repetitive positioning errors, improving processing efficiency. At the same time, this process is highly compatible with the core architecture of curtain wall profile processing, adapting to the characteristics of different profiles, and enabling flexible and high-precision processing of multiple types of door and window profiles on the same production line.

[0025] As can be seen from the above technical solutions, the present invention has the following advantages: This invention provides a profile sawing device, a profile processing system, and its working method. Through the multi-degree-of-freedom coordination of the moving column, lifting slide, swing arm, and sawing components, only one sawing actuator is needed to achieve multi-position, multi-angle sawing of profiles, reducing the number of independent moving parts, minimizing the accumulation of errors in multiple motion chains, ensuring processing accuracy, and simultaneously reducing the equipment's footprint. By incorporating a second sawing clamping component capable of moving along the X-axis, material receiving can be achieved during sawing, providing far-end rigid support for long profiles to eliminate sagging deformation caused by the profile's own weight, thereby ensuring the perpendicularity and length accuracy of the sawn surface. Furthermore, the device fixes both ends of the profile during sawing, enhancing system rigidity and ensuring stability during high-feed cutting. The device is further enhanced by two vertical clamping units and... The horizontal clamping unit, in conjunction with the figure-eight-shaped horizontal clamping blocks, applies constraint to the profile from multiple directions, effectively suppressing displacement and torsion during sawing, and improving clamping stability and processing accuracy. The movable auxiliary support plate effectively supports the ends of the profile, preventing insufficient support strength caused by excessive extension beyond the fixed or movable clamping base during inclined sawing, thus ensuring the perpendicularity and length accuracy of the saw cut surface. The servo motor drives the auxiliary support plate, accurately determining its extension distance as needed to ensure sufficient support strength while avoiding interference with the saw blade. The combination of upper clamping roller, lower clamping roller, movable roller, and fixed roller creates multi-point constraint at the sawing feed end, adapting to different cross-sectional shapes. The profile conveying system reduces offset and slippage during feeding, improving conveying stability. A movable seat provides feeding assistance during the feeding process, offering active driving force at the profile's front end to prevent long profiles from shifting or twisting during long-distance transport. It also reduces the reaction force of the profiles on the feeding device, significantly minimizing wear on related components. The movable seat ensures accurate initial positioning and stable conveying of the curtain wall profiles. The sawing clamping assembly actively approaches and presses against the profiles, effectively preventing sagging and swaying of large-section heavy profiles under long overhang. Furthermore, for inclined sawing, an auxiliary support plate extends to fill support blind spots, eliminating localized deflection. The continuous clamping of the discharge assembly throughout the sawing process firmly suppresses... The impact vibration and displacement at the moment of cutting are controlled. The above-mentioned links together construct a full-stroke, high-rigidity constraint system for the curtain wall profile, which eliminates loosening, deformation and secondary positioning errors in the processing from the root. It significantly improves the verticality, flatness and relative position accuracy between the hole system and the end face of the curtain wall profile sawing end face. Through the receiving of the material by the moving seat and the second sawing clamping component, the material output component is clamped throughout the sawing process, which effectively suppresses the shaking and cutting impact when sawing small cross-section profiles, ensuring the flatness of the end face and dimensional accuracy. Combined with the auxiliary support plate extending as needed when sawing at an angle, it ensures the processing accuracy. It can complete multi-surface drilling and milling and multi-angle sawing in one clamping, and supports parallel processing of non-X-direction moving drilling and milling, which greatly reduces process switching and repeated positioning errors and improves processing efficiency.Meanwhile, this process is highly compatible with the core architecture of curtain wall profile processing, adapting to the characteristics of different profiles, and enabling flexible, high-precision processing of multiple types of door and window profiles on the same production line.

[0033] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Implementation Method 1 like Figure 1 As shown, this specific embodiment provides a profile sawing device, including a sawing base 1. A movable column 13, which moves along the X-direction, is mounted on the sawing base 1. The movable column 13 is slidably engaged with the base via a guide rail slider pair and is precisely positioned by a ball screw driven by a servo motor. A lifting slide 14, which moves up and down along the Z-direction, is mounted on the movable column 13. It also moves up and down via a servo motor and a ball screw transmission mechanism. The lifting slide 14 is connected to the movable column 13 via a corresponding guide rail slider pair. A swing arm 16 is rotatably connected to the lifting slide 14. The swing arm 16 extends along the Y-direction, and one end of it is rotatably connected to the lifting slide 14 via a bearing. Specifically, the swing arm... One end of the swing arm 16 is connected to the drive shaft, which is rotatably mounted on the lifting slide 14 via bearings. The lifting slide 14 contains a servo motor and a reducer connected to it. The reducer is connected to the drive shaft via a coupling. The other end of the swing arm 16 is rotatably mounted with a sawing assembly 4. The sawing assembly 4 includes a saw blade 2 driven by a sawing motor 3. The sawing motor 3 is mounted with a rotating seat. The rotation of the rotating seat is the same as that of the swing arm 16, and will not be described in detail here. Through the cooperation of the swing arm 16 and the sawing assembly 4, the saw blade 2 can swing at multiple angles to meet various sawing angles. In this specific embodiment, the feeding direction of the profile is the X direction, the direction perpendicular to the X direction in the horizontal plane is the Y direction, and the vertical direction is the Z direction.

[0035] In this specific embodiment, the sawing feed motion (X-axis), lifting motion (Z-axis), and angle adjustment motion are all integrated into a set of columns and swing arms 16. Only one sawing actuator is needed to cover multiple sawing angles and positions: by moving the column 13 along the X-axis, the saw blade 2 can be positioned at any sawing position along the length of the profile, including the end-cutting position, the middle fixed-length cutting position, and the tail cutting position; by moving the lifting slide 14 along the Z-axis, the height of the saw blade 2 can be adjusted to adapt to profiles with different cross-sections; and by moving the swing arm 16 around the lifting slide 14... The rotation of the saw blade 2 and the rotation of the sawing assembly 4 around the end of the swing arm 16 allow the saw blade 2 to swing to any angle, thereby realizing vertical sawing (90°), bevel sawing (such as 45°, 30° and other commonly used angles), and composite angle sawing of the profile end. This fundamentally reduces the number of independent moving parts and avoids the problem of overlapping positioning errors caused by different wear and thermal deformation of the lateral processing host and the vertical processing host in the prior art. It ensures the accuracy of the sawing angle and position, and at the same time greatly reduces the space occupied by the equipment, which is conducive to the compact layout of the production line.

[0036] like Figures 1 to 3 As shown, to ensure the cutting stability of the profile during the sawing process, this specific embodiment configures a sawing clamping assembly 12 and a sawing clamping assembly 21 arranged sequentially along the X direction in the sawing device. The sawing clamping assembly 12 includes a fixed clamping base 5, which is bolted to the feed end of the sawing base 1 and is used to clamp the profile near the feed side at the sawing position. The sawing clamping assembly 21 includes a movable clamping base 20, which is slidably disposed at the sawing output end along the X direction via a guide rail slider pair and is driven by an independent servo motor and lead screw, enabling it to reciprocate along the X direction. The movable clamping base 20 also moves along the X direction... A sliding discharge component 22 is provided to receive the cut profile segment and remove it from the processing area. The movable clamping base 20 can actively move towards the feeding end during sawing to receive the material. This provides rigid support at the far end of the long profile, effectively eliminating the drooping deformation caused by the profile's own weight, and ensuring the perpendicularity and length accuracy of the saw cut surface. On the other hand, the receiving action shortens the feeding stroke of the feeding device 34, reduces the difficulty of long-distance pushing, and fixes both ends of the profile during sawing, significantly enhancing the rigidity of the entire process system and ensuring stability under high feed rate cutting conditions.

[0037] like Figures 1 to 3As shown in this specific embodiment, both the sawing clamping assembly 12 and the sawing clamping assembly 21 include a vertical clamping unit 1 8, a vertical clamping unit 2 7, and a horizontal clamping unit 6. The vertical clamping unit 1 8 includes a pressure plate 1 24, and the vertical clamping unit 2 7 includes a pressure plate 2 25. The pressure plate 1 24 and the pressure plate 2 25 each achieve vertical lifting movement through a lifting drive element (such as a cylinder or hydraulic cylinder), thereby clamping the upper surface of the profile from above. The horizontal clamping unit 6 includes a horizontal clamping block 26. The horizontal clamping block 26 can move along the X-axis through an obliquely arranged guide rail and a drive element (such as a cylinder or hydraulic cylinder). The profile is moved at a certain angle (45° in this specific embodiment) to apply lateral clamping force. A positioning plate 15 is vertically mounted on both the fixed clamping base 5 and the movable clamping base 20. This positioning plate 15 is arranged opposite to the horizontal clamping block 26, forming a horizontal clamping pair. The two horizontal clamping blocks 26 are arranged in a V-shape on both sides of the sawing assembly 4. This V-shape arrangement pushes the profile towards the positioning plate 15 simultaneously, generating a constraint force towards the sawing center, effectively suppressing the profile's torsion and lateral displacement in the horizontal plane during sawing. Vertical clamping unit 1 8 and vertical clamping unit 2 7 are arranged at intervals along the X-direction, adapting to profiles of different lengths and cross-sectional shapes. This ensures sufficient vertical constraint near the sawing position. Combined with the multi-directional force application of the horizontal clamping unit 6, they form a multi-point, multi-angle constraint system for the profile in both vertical and horizontal directions, significantly improving clamping stability and vibration resistance.

[0038] In situations involving inclined sawing or large profile overhangs, the conventional clamping position is often far from the sawing point, which can easily lead to insufficient end-support rigidity of the profile. Figure 2 and Figure 3As shown, for this purpose, an auxiliary support plate 11 is slidably provided on the fixed clamping base 5 and / or the movable clamping base 20 along the X direction. The vertical pressing unit 8 and the positioning plate 15 are directly installed on the auxiliary support plate 11. The auxiliary support plate 11 can extend or retract along the X direction on its respective base. When the end of the profile needs to be sawn at an angle, causing the profile to protrude a large length from the fixed clamping base 5 and / or the movable clamping base 20, the auxiliary support plate 11 extends towards the sawing assembly 4, causing the vertical pressing unit 8 and the positioning plate 15 to move forward accordingly. This applies pressure and positioning to the profile closer to the sawing position, significantly shortening the suspension distance between the sawing point and the clamping point of the profile, and avoiding the profile protruding due to the sawing point. The excessive distance causes insufficient support rigidity and profile sagging, ensuring the verticality and length accuracy of the cross-section during inclined sawing. Under normal working conditions, the auxiliary support plate 11 can be retracted to its original position without affecting the normal sawing space. In this specific embodiment, the auxiliary support plate 11 is slidably installed on the fixed clamping base 5 and the movable clamping base 20 along the X direction. The vertical pressing unit 8 uses a cylinder to drive the pressure plate 24 to rise and fall. The cylinder is installed on the auxiliary support plate 11 through a mounting bracket. The upper surface of the auxiliary support plate 11 is flush with the upper surface of the fixed clamping base 5 and the movable clamping base 20. The auxiliary support plate 11 is also provided with an avoidance slope. The angle between the avoidance slope and the X-axis is consistent with the moving direction of the horizontal pressing block 26. Furthermore, in this specific embodiment, the auxiliary support plate 11 is slidably mounted on the fixed clamping base 5 and the movable clamping base 20 via a guide rail slider pair, and is connected to an auxiliary motor via a transmission mechanism (such as a lead screw and nut mechanism or a gear and rack mechanism). This auxiliary motor is a servo motor with closed-loop control capability, which can precisely drive the auxiliary support plate 11 to move to the set position according to the control system command and provide real-time feedback on the actual position. Through servo drive, the extension distance of the auxiliary support plate 11 can be precisely calculated and adjusted according to the overhang length and sawing angle of the current profile, which not only ensures sufficient support strength, but also avoids the auxiliary support plate 11 from extending too far and interfering with the rotating saw blade 2, thus ensuring the safety and reliability of the sawing process.

[0039] For example Figure 1 and Figure 3As shown in this specific embodiment, the discharge assembly 22 can adopt the following specific structure: The discharge assembly 22 includes a support slide 29, which is bolted to the discharge end of the movable clamping base 20 and moves together with the movable clamping base 20. A discharge slide 18 is slidably disposed on the support slide 29 along the X direction. The discharge slide 18 is connected to the support slide 29 through a guide rail slider pair. The discharge slide 18 moves in the X direction on the support slide 29 through a drive mechanism. The drive mechanism includes a corresponding servo motor, which drives the discharge slide 18 to move through a lead screw and nut pair. A fixed clamping plate 17 is disposed on one end of the discharge slide 18 near the positioning plate 15. The fixed clamping plate 17 is fixed relative to the discharge slide 18. A movable clamping plate 19 is also slidably disposed on the discharge slide 18 along the Y direction through a corresponding guide rail slider pair. The movable clamping plate 19 is arranged opposite to the fixed clamping plate 17 and is driven by a Y-direction drive mechanism, enabling it to move towards the fixed clamping plate 17. The fixed clamping plate 17 moves in one direction to clamp the profile, or moves away from the fixed clamping plate 17 to release the profile. The Y-axis drive mechanism includes a corresponding servo motor, which drives the moving clamping plate 19 to move through a lead screw and nut pair. During the sawing process, the fixed clamping plate 17 and the moving clamping plate 19 on the discharge slide 18 work together to clamp the profile. After sawing, the discharge slide 18 moves along the X-axis to remove the profile segment, realizing the integrated automatic operation of cutting, clamping and discharge. This improves the clamping rigidity of the profile during sawing and avoids the free fall of the cut profile segment, which could cause end face collision or damage to the saw blade 2. The clamping position of the discharge component 22 is set according to the length of the finished profile. When the finished product is long, the fixed clamping plate 17 and the moving clamping plate 19 clamp at a position farther away from the positioning plate 15X in the X direction. When the finished product is short, the fixed clamping plate 17 and the moving clamping plate 19 clamp at a position closer to the positioning plate 15X in the X direction, further improving the sawing clamping stability.

[0040] like Figure 2As shown in this specific embodiment, a clamping bracket 9 is vertically arranged at the feeding end of the fixed clamping base 5. An upper clamping roller 10, which is liftable and rotatable, is mounted on the clamping bracket 9. Simultaneously, a lower clamping roller 23, which is rotatable, is also mounted at the feeding end of the fixed clamping base 5. The upper clamping roller 10 and the lower clamping roller 23 are arranged vertically opposite each other, and the distance between them can be adjusted according to the profile height to clamp the profile from a vertical direction. A fixed roller 27 is vertically rotatably arranged at the feeding end of the fixed clamping base 5 via a corresponding rotating shaft. A movable roller 28 is vertically and movably arranged on the clamping bracket 9. The movable roller 28 can move closer to or further away from the fixed roller 27 in the horizontal direction (Y direction) to clamp the profile from the side. In this specific embodiment, the upper clamping roller 10 and the lower clamping roller 23 are vertically rotatable and rotatable. Two rollers 23 are provided. A corresponding cylinder is provided on the clamping bracket 9. The piston rod of the cylinder is set downward and connected to the upper mounting base. The upper mounting base is rotatably mounted on the upper clamping roller 10 via a rotating shaft. A lower mounting base is provided on the upper surface of the fixed clamping base 5. The lower mounting base is rotatably mounted on the lower clamping roller 23 via a rotating shaft. The movable roller 28 on the clamping bracket 9 is driven by a corresponding cylinder. The upper clamping roller 10, lower clamping roller 23, fixed roller 27 and movable roller 28 can all rotate freely. Therefore, while clamping the profile, the profile is allowed to slide smoothly along the X direction, reducing the conveying friction resistance. This multi-point roller clamping structure can adapt to profiles with various cross-sectional shapes, effectively reducing the offset and slippage of the profile during long-distance feeding, and ensuring the accuracy of the feeding direction and position.

[0041] Implementation Method 2 like Figure 4 and Figure 5As shown, this specific embodiment provides a profile processing system, including a feeding device 34, a drilling and milling composite processing device 35, and a profile sawing device 36 of Embodiment 1. The feeding device 34 is located at the feeding end of the drilling and milling composite processing device 35 and is used to feed the profiles to be processed one by one into the system. The drilling and milling composite processing device 35 includes a drilling and milling base 45, which is located at the feeding end of the sawing base 1, that is, the drilling and milling process is before the sawing process. A gantry frame 40 is provided on the drilling and milling base 45. The gantry frame 40 consists of two opposing support columns 39 and a crossbeam 38 connected to the upper ends of the two support columns 39, forming a portal frame structure straddling the profile conveying path. The structure includes a movable seat 41 that slides along the X direction on the drilling and milling base 45. The movable seat 41 serves as a platform for carrying and conveying the profile in the drilling and milling station. Drilling and milling processing components 37 are provided on the movable seat 41, the crossbeam 38, and the two support columns 39, for a total of four drilling and milling processing components 37. These components are respectively arranged below the profile (on the movable seat 41), above the profile (on the crossbeam 38), and on the left and right sides (on the two support columns 39). Each of the four drilling and milling processing components 37 is driven independently and is used to drill and mill the lower surface, upper surface, and two sides of the profile, respectively. A drilling and milling clamping component 44 is also provided on the top of the movable seat 41 to clamp the profile on the movable seat 41 during the drilling and milling process.

[0042] In this specific embodiment, the movable seat 41 can actively move along the X direction when the feeding device 34 feeds the material, which plays a role in assisting the feeding and provides active driving force at the front end of the profile. This prevents the long profile from shifting or twisting due to its own weight during long-distance transportation. At the same time, it reduces the drag reaction force of the profile on the feeding device 34 and reduces the wear of the related transmission components of the feeding device 34. Meanwhile, after the tail section is drilled and milled, the movable seat 41 clamps the tail section of the profile and transports it from the drilling and milling station to the sawing feed end, realizing a seamless connection between drilling and milling and sawing.

[0043] like Figure 5 As shown, in this specific embodiment, the drilling and milling clamping assembly 44 can adopt the following specific structure: The drilling and milling clamping assembly 44 includes a clamping frame, two upper clamping rollers 42, two lower clamping rollers, two fixed rollers 43, and two movable rollers. The clamping frame is arranged opposite to the upper surface of the movable seat 41. The clamping frame is connected to the movable seat 41 through a cylinder. The two upper clamping rollers 42 are rotatably mounted on the clamping frame through a rotating shaft. The lower clamping rollers are rotatably mounted on the upper surface of the movable seat 41 through corresponding rotating shafts. The fixed rollers 43 are vertically and rotatably mounted on the movable seat 41 through corresponding rotating shafts. The movable rollers are moved along the Y direction on the movable seat 41 through corresponding cylinders and are arranged opposite to the fixed rollers 43.

[0044] In this specific embodiment, the drilling and milling machining components 37 in the four directions correspond to the slot machining unit 1, slot machining unit 2, slot machining unit 3, and slot machining unit 4 in the applicant's prior patent with authorization announcement number CN223368741U. Slot machining unit 1, slot machining unit 2, slot machining unit 3, and slot machining unit 4 all include a cutter head assembly. Multiple cutter head assemblies can move independently along the X-axis, Y-axis, and Z-axis, and can rotate at corresponding angles to perform machining. Their structure and working principle will not be described in detail here. The difference is that in this specific embodiment, the cutter head assembly includes two electric spindles with tools of different machining ranges. Each electric spindle is connected to a cylinder, which enables the corresponding tool to extend for drilling and milling, greatly expanding the drilling and milling range of this device.

[0045] like Figure 4 As shown in this specific embodiment, the feeding device 34 has the same structure as the feeding device 34 in the applicant's prior patent with authorization announcement number CN223368741U, including a support frame 31. A feeding robot 30 is movably arranged on the support frame 31 along the X-axis. The support frame 31 is provided with a positioning component 32 and a support component 33. The feeding robot 30 can push the profile to move along the support component 33 for feeding. The feeding device 34 is prior art, and its structure and working principle will not be described in detail here.

[0046] Implementation Method 3 This specific embodiment provides a working method for a profile processing system, using the aforementioned profile processing system. When processing curtain wall profiles, the following steps are included: S01: The feeding device 34 feeds the curtain wall profile into the upper part of the moving seat 41 along the X direction. The curtain wall profile is then clamped by the drilling and milling clamping assembly 44 and moved along the X direction. Specifically, the feeding robot 30 of the feeding device 34 clamps the end of the curtain wall profile and pushes it toward the drilling and milling composite processing device 35. When the end of the curtain wall profile passes through the drilling and milling clamping assembly 44 by a set distance, the drilling and milling clamping assembly 44 clamps the end of the curtain wall profile and moves toward the gantry 40 until the end of the curtain wall profile moves to the set position. The saw blade 2 rotates to the corresponding position to perform a flush sawing on the end of the curtain wall profile. Alternatively, the corresponding drilling and milling processing assembly 37 is activated to perform drilling and milling processing on the upper surface, two side surfaces and the lower surface of the end of the curtain wall profile. After processing is completed, the assembly continues to move toward the saw blade 2 to another set position and then performs a flush sawing. S02: Activate the corresponding drilling and milling assembly 37 to perform drilling and milling on the upper surface, side surfaces, and lower surface of the curtain wall profile, respectively. The drilling and milling assembly 37 arranged on the crossbeam 38 feeds vertically from above the curtain wall profile to process the mounting holes, drainage grooves, or thermal insulation strip mounting grooves on the upper surface. The drilling and milling assembly 37 arranged on the moving base 41 feeds vertically from below the curtain wall profile to process the screw holes on the lower surface. The drilling and milling assembly 37 arranged on the two support columns 39 feeds horizontally along the Y direction from the left and right sides of the curtain wall profile to process the connecting holes, locking grooves, or rubber strip mounting grooves on the two sides, respectively. All four drilling and milling assemblies 37 can move independently along the X, Y, and Z directions, enabling simultaneous or sequential processing of different surfaces of the curtain wall profile at the same X-direction position. The profile can be moved along the X direction to different length positions for segmented processing. During the entire drilling and milling process, the moving seat 41 serves as the bearing platform and positioning reference for the curtain wall profile. The clamping force provided by the top drilling and milling clamping component 44 is balanced with the cutting force of the four drilling and milling processing components 37, ensuring that the curtain wall profile does not shift or vibrate during processing. All features such as holes, grooves, and pits on the curtain wall profile are based on the flush end face established in step S01 as the zero point of the length direction reference, thereby ensuring the relative positional accuracy between each processing feature. This four-surface synchronous or sequential drilling and milling method enables the curtain wall profile to complete all drilling and milling in one clamping, avoiding the accumulation of positioning errors caused by multiple flipping clamping in traditional processes, and significantly improving the positional accuracy, symmetry, and consistency of holes and grooves on the curtain wall profile. S03: After drilling and milling, the feeding device 34 feeds the curtain wall profile into the sawing feed end. If it is a sawing of the tail section, the moving seat 41 needs to clamp the curtain wall profile, and the profile sawing device 36 needs to approach the feeding. At the same time, the moving clamping base 20 of the profile sawing device 36 moves to the set position in the direction of the fixed clamping base 5. The curtain wall profile passes through the sawing clamping assembly 12 and extends above the moving clamping base 20 of the sawing clamping assembly 21. When it is determined that the end of the curtain wall profile needs to be sawn at an angle, the auxiliary support plate 11 extends in the direction of the sawing assembly 4. In this process, the sawing clamping assembly 21 provides the front active driving force, avoiding the feed deviation caused by the tail of the curtain wall profile sagging due to its own weight when pushed a long distance by the feeding device 34 alone. At the same time, the control system adjusts the feed according to the processing... The program determines whether the end of the current tail section needs to be sawed at an angle. If so (e.g., 45° or 30° angled sawing), the auxiliary support plate 11 extends along the X direction towards the sawing assembly 4 to a set position under the drive of the servo motor. This position is calculated based on the sawing angle and the cross-section of the curtain wall profile. This ensures that the front end of the auxiliary support plate 11 is as close as possible to the sawing point but does not interfere with the path of the saw blade 2. After the auxiliary support plate 11 extends, the vertical clamping unit 8 and the positioning plate 15 on it move forward accordingly, providing vertical clamping and lateral positioning near the sawing point. This significantly shortens the suspension distance between the curtain wall profile and the clamping point, effectively resisting the sagging and swaying caused by the oblique cutting force, and ensuring the angle accuracy and surface quality of the end face during inclined sawing. After the moving clamping base 20 is in place and the auxiliary support plate 11 extends as needed, the system completes the position preparation before sawing. S04: After the vertical clamping unit 8 and / or the vertical clamping unit 7 and the horizontal clamping unit 6 of the sawing clamping assembly 21 press the curtain wall profile against the corresponding positioning plate 15, the movable clamping base 20 moves away from the fixed clamping base 5 to a set position to leave clearance space for sawing; specifically, the vertical clamping unit 8, the vertical clamping unit 7 and the horizontal clamping unit 6 on the sawing clamping assembly 21 act simultaneously or sequentially to press the corresponding surface of the curtain wall profile, pressing the side of the curtain wall profile against the corresponding positioning plate 15. For large-section curtain wall profiles, the vertical clamping unit 8 and the vertical clamping unit 7 can be activated simultaneously at two different positions along the length of the curtain wall profile. A vertical clamping force is applied to enhance clamping stability. For cases with small cross-sections or limited clamping space, only the vertical clamping unit 8 can be activated. After the curtain wall profile is reliably clamped to the positioning plate 15, the movable clamping base 20 moves along the X direction away from the fixed clamping base 5 to a set position under the drive of the servo motor. This position is calculated by the control system based on the thickness of the saw blade 2, the sawing angle, and the sawing position. The purpose is to remove the sawing clamping assembly 21 from the sawing path of the saw blade 2, making sufficient space for the saw blade 2 to cut into the curtain wall profile, avoiding interference between the saw blade 2 and any part of the movable clamping base 20 during the sawing process, and providing a stable premise for the clamping of the next sawing clamping assembly 12 and high-precision sawing.

[0047] S05: The vertical clamping unit 8 and / or the vertical clamping unit 7 and the horizontal clamping unit 6 of the sawing clamping assembly 12 press the curtain wall profile against the corresponding positioning plate 15. S06: Drive the movable column 13 to move along the X-direction to the sawing position, drive the lifting slide 14 to move along the Z-direction to the sawing height, and drive the swing arm 16 and the sawing assembly 4 to rotate, so that the saw blade 2 rotates to the corresponding sawing angle; specifically, the control system calculates the target X-direction position of the movable column 13, the target Z-direction height of the lifting slide 14, and the target rotation angle of the swing arm 16 and the sawing assembly 4 according to preset sawing process parameters (including the cross-sectional dimensions of the curtain wall profile, the sawing length, the sawing angle, etc.). During operation, the movable column 13 moves along the X-direction to the sawing position, which corresponds to the cutting point of the saw blade 2 in the length direction of the curtain wall profile. The lifting slide 14 moves along the Z-guide rail on the movable column 13 to the sawing height under the drive of the servo motor, and the swing arm 16 rotates around it in the lifting... The rotation axis on the slide 14 rotates, while the sawing assembly 4 rotates around its rotation axis at the end of the swing arm 16. The rotation angle of the two is calculated by the control system based on the target sawing angle (e.g., 90° vertical sawing, 45° oblique sawing, or other arbitrary angles). When more complex compound angle sawing is required, the rotation of the swing arm 16 and the rotation of the sawing assembly 4 cooperate with each other, and the saw blade 2 can be arbitrarily oriented in three-dimensional space through the linkage of the two axes. This dual-rotation axis design makes the sawing angle of the saw blade 2 no longer limited to the movement range of a single rotation axis, but can achieve a wider range of sawing angles through the combination of the rotation angles of the swing arm 16 and the rotation angle of the sawing assembly 4. Moreover, the movement ranges of the two axes compensate for each other, avoiding excessive occupation of structural space when a single rotation axis needs to rotate at a large angle. S07: The sawing assembly 4 is activated to perform sawing. During the sawing process, the discharge assembly 22 maintains clamping on the curtain wall profile. Simultaneously, if there are drilling and milling operations on the curtain wall profile that do not require X-axis movement, the corresponding drilling and milling assembly 37 performs drilling and milling on the curtain wall profile. Specifically, the sawing motor 3 drives the saw blade 2 to rotate at high speed for sawing. During the sawing process, to improve clamping rigidity, the discharge assembly 22 maintains clamping on the curtain wall profile. When the finished length of the curtain wall profile is long, the clamping point of the discharge assembly 22 is far from the positioning plate 15 on the moving clamping base 20. When the finished length of the curtain wall profile is short, the discharge assembly... The clamping point of component 22 is close to the positioning plate 15 on the movable clamping base 20. At the same time, if a certain processing feature on the curtain wall profile (such as a hole or groove within the coverage of the current drilling and milling station) has not been processed in the previous drilling and milling process, and the processing content is within the stroke range of the drilling and milling processing component 37 in the X direction, it can be processed without moving the curtain wall profile with the movable base 41. Then the control system starts one or more corresponding drilling and milling processing components 37 to perform drilling and milling processing on the curtain wall profile while sawing is being carried out. This overlaps the two processes that originally needed to be completed in sequence in time, greatly shortening the total processing cycle of a single curtain wall profile. S08: After sawing is completed, the vertical clamping unit 1 8 and / or the vertical clamping unit 2 7 and the horizontal clamping unit 6 are released, and the discharge assembly 22 removes the cut curtain wall profile.

[0048] This invention ensures accurate initial positioning and stable conveying of the curtain wall profile through the material receiving mechanism 41. The sawing clamping component 21 actively approaches and presses against the material, effectively preventing the large-section heavy curtain wall profile from sagging and swaying under its own weight in a long overhang state. On this basis, for inclined sawing, the auxiliary support plate 11 extends to fill the support blind area and eliminate local flexural deformation. The continuous clamping of the discharge component 22 throughout the sawing process firmly suppresses the impact vibration and displacement at the moment of cutting. The above links together construct a full-stroke, high-rigidity constraint system for the curtain wall profile, eliminating loosening, deformation and secondary positioning errors in the processing from the root, and significantly improving the verticality, flatness and relative position accuracy between the hole system and the end face of the curtain wall profile sawing end face.

[0049] After S08, the unloading component 22 removes the cut curtain wall profile and completes the unloading. The system then enters the preparation and execution stage of the next processing cycle. After unloading, the unloading slide 18 returns to the initial waiting position along the X direction, waiting to receive the next section of the cut curtain wall profile. At the same time, the control system determines whether the remaining length of the current curtain wall profile is sufficient to continue processing the next finished section. If the remaining length is greater than or equal to the set length of the next finished section (including saw cut loss), the system automatically jumps back to S02 and repeats the drilling, milling, clamping, sawing, and unloading cycle from S02 to S08 until the remaining length of the current curtain wall profile is insufficient to process the next finished section. When the remaining length is less than the set length of the next finished section, the system enters the tail material processing stage. After all finished sections and tail materials of a curtain wall profile have been processed, the moving seat 41 completely returns to the initial loading position of the drilling and milling station. The loading device 34 starts and repeats all the steps from S01 to S08 to begin the complete processing cycle of the next curtain wall profile.

[0050] Furthermore, when processing door and window profiles, the following steps are included: T01: The feeding device 34 feeds the door and window profile into the upper part of the moving seat 41 along the X direction. After the door and window profile is clamped by the drilling and milling clamping assembly 44, it moves along the X direction to transport the end of the door and window profile to the set position. The specific process is the same as S01 and will not be repeated. T02: Start the corresponding drilling and milling assembly 37 to perform drilling and milling on the upper surface, two side surfaces and the lower surface of the door and window profile respectively; T03: After drilling and milling, the feeding device 34 feeds the door and window profile into the sawing feed end, and the movable clamping base 20 moves to the set position in the direction of the fixed clamping base 5, so that the door and window profile passes through the sawing clamping assembly 12 and extends to the upper part of the movable clamping base 20 of the sawing clamping assembly 21. If it is the sawing of the tail section, the movable seat 41 clamps the door and window profile and moves it closer to the profile sawing device 36 for feeding. At the same time, when it is determined that the end of the door and window profile needs to be sawed at an angle, the auxiliary support plate 11 extends in the direction of the sawing assembly 4. T04: After the vertical pressing unit 8 and the horizontal pressing unit 6 of the sawing clamping assembly 21 press the door and window profiles against the corresponding positioning plate 15, the movable clamping base 20 moves away from the fixed clamping base 5 to a set position to leave clearance space for sawing. T05: The vertical clamping unit 8 and the horizontal clamping unit 6 of the sawing clamping assembly 12 press the door and window profiles against the corresponding positioning plate 15. T06: Drive the movable column 13 to move along the X direction to the sawing position, drive the lifting slide 14 to move along the Z direction to the sawing height, and drive the swing arm 16 and the sawing assembly 4 to rotate, so that the saw blade 2 rotates to the corresponding sawing angle; T07: Start the sawing assembly 4 to perform sawing. During the sawing process, the discharge assembly 22 keeps the door and window profile clamped. At the same time, if there is drilling and milling work on the door and window profile that does not require X-axis movement, the corresponding drilling and milling assembly 37 performs drilling and milling work on the door and window profile. T08: After sawing is completed, the vertical clamping unit 8 and the horizontal clamping unit 6 are released, and the discharge assembly 22 removes the cut door and window profiles.

[0051] This specific embodiment effectively suppresses shaking and cutting impact during the sawing of small cross-section profiles by receiving the material through the moving seat 41 and the sawing clamping component 21, and clamping the material throughout the sawing process by the output component 22, ensuring the flatness of the end face and dimensional accuracy. Combined with the auxiliary support plate 11 extending as needed during inclined sawing, it ensures processing accuracy. It can complete multi-surface drilling and milling and multi-angle sawing in one clamping, and supports parallel processing of non-X-direction moving drilling and milling, which greatly reduces process switching and repeated positioning errors and improves processing efficiency. At the same time, the processing flow of door and window profiles and curtain wall profiles in this specific embodiment is highly compatible, realizing flexible and high-precision processing of multiple types of door and window profiles on the same production line.

[0052] As can be seen from the above specific embodiments, the present invention has the following beneficial effects: 1. By cooperating with the moving column 13, lifting slide 14, swing arm 16 and sawing assembly 4, multiple positions and angles of profile sawing can be achieved with only one sawing actuator, reducing the number of independent moving parts, reducing the accumulation of errors in multiple motion chains, ensuring processing accuracy, and reducing the space occupied by the equipment. 2. By setting a sawing clamping component 21 that moves along the X direction, it can actively receive the material during sawing and feeding, provide far-end rigid support for long profiles to eliminate drooping deformation, ensure the perpendicularity and length accuracy of the saw cut surface, and fix both ends of the profile during sawing, thereby enhancing the rigidity of the system and ensuring the stability of large feed cutting. 3. By using two vertical clamping units and horizontal clamping unit 6 in conjunction with the figure-eight shaped lateral clamping blocks, the profile is constrained from multiple directions, effectively suppressing displacement and torsion during the sawing process, and improving clamping stability and processing accuracy. 4. The movable auxiliary support plate 11 effectively supports the end of the profile, avoiding insufficient support rigidity due to excessive protrusion distance during inclined sawing, and ensuring the perpendicularity and length accuracy of the saw cut surface. 5. The auxiliary support plate 11 is moved by a servo motor, which can precisely control the extension distance, ensuring sufficient support strength while avoiding interference with the saw blade 2; 6. By combining the upper clamping roller 10, the lower clamping roller 23, the movable roller 28, and the fixed roller 27, multi-point constraints are formed at the sawing feed end, which can adapt to the conveying of profiles with different cross sections, reduce deviation and slippage during the feeding process, and improve the conveying stability. 7. By setting the movable seat 41, an active driving force can be provided during feeding, which can prevent long profiles from shifting or twisting during long-distance transportation, while reducing the reaction force of the profiles on the feeding device 34 and reducing the wear of related parts of the feeding device 34. 8. The moving seat 41 ensures accurate initial positioning and stable conveying of the curtain wall profile. The sawing clamping component 21 actively receives and presses the material to prevent the large cross-section heavy material from sagging and swaying under its own weight in the long overhang state. The auxiliary support plate 11 extends to fill the support blind area for inclined sawing. The discharge component 22 clamps the material throughout the process to suppress the cutting impact. Together, they form a high rigidity constraint system throughout the entire stroke, which significantly improves the verticality, flatness and relative position accuracy between the hole system and the end face of the curtain wall profile sawing end face. 9. The material receiving and discharging components 22 of the moving seat 41 and the sawing clamping component 21 are used to clamp the material throughout the process, which effectively suppresses the shaking and cutting impact when sawing small cross-section profiles, ensuring the flatness of the end face and dimensional accuracy. Combined with the auxiliary support plate 11 extending as needed and clamping in one go, multi-surface drilling and milling and multi-angle sawing can be completed, and parallel processing is supported. This greatly reduces process switching and repeated positioning errors, improves processing efficiency, and is highly compatible with the curtain wall profile processing architecture, realizing flexible and high-precision processing of multiple types of profiles on the same production line.

The profile sawing device is close to the feeding, so that the moving clamping base (20) moves to the set position in the direction of the fixed clamping base (5), so that the curtain wall profile passes through the sawing clamping assembly one (12) and extends to the moving clamping base (20) of the sawing clamping assembly two (21). At the same time, when it is determined that the end of the curtain wall profile needs to be sawed at an angle, the auxiliary support plate (11) extends in the direction of the sawing assembly (4). S04: After the vertical clamping unit 1 (8) and / or the vertical clamping unit 2 (7) and the horizontal clamping unit (6) of the sawing clamping assembly 2 (21) clamp the curtain wall profile to the corresponding positioning plate (15), the movable clamping base (20) moves away from the fixed clamping base (5) to a set position to leave clearance space for sawing; S05: The vertical clamping unit 1 (8) and / or the vertical clamping unit 2 (7) and the horizontal clamping unit (6) of the sawing clamping assembly 1 (12) clamp the curtain wall profile to the corresponding positioning plate (15). S06: Drive the movable column (13) to move along the X direction to the sawing position, drive the lifting slide (14) to move along the Z direction to the sawing height, and drive the swing arm (16) and the sawing assembly (4) to rotate, so that the saw blade (2) rotates to the corresponding sawing angle; S07: Start the sawing assembly (4) to perform sawing. During the sawing process, the discharge assembly (22) holds the curtain wall profile. At the same time, if there is drilling and milling work on the curtain wall profile that does not require X-axis movement, the corresponding drilling and milling assembly (37) performs drilling and milling work on the curtain wall profile. S08: After sawing is completed, the vertical clamping unit one (8) and / or the vertical clamping unit two (7) and the horizontal clamping unit (6) are released, and the discharge assembly (22) removes the cut curtain wall profile.

The working method of the profile processing system as described in claim 9, characterized in that, When processing door and window profiles, the following steps are included: T01: The feeding device (34) feeds the door and window profiles into the upper part of the moving seat (41) along the X direction, and the door and window profiles are clamped by the drilling and milling clamping assembly (44) and then moved along the X direction; T02: Start the corresponding drilling and milling assembly (37) to perform drilling and milling on the upper surface, two side surfaces and the lower surface of the door and window profile respectively; T03: After drilling and milling, the feeding device (34) feeds the door and window profile into the sawing feed end. If it is the sawing of the tail section, the moving seat (41) needs to clamp the door and window profile. The profile sawing device is close to the feeding, so that the moving clamping base (20) moves to the set position in the direction of the fixed clamping base (5), so that the door and window profile passes through the sawing clamping assembly one (12) and extends to the moving clamping base (20) of the sawing clamping assembly two (21). At the same time, when it is determined that the end of the door and window profile needs to be sawed at an angle, the auxiliary support plate (11) extends in the direction of the sawing assembly (4). T04: After the vertical pressing unit (8) and the horizontal pressing unit (6) of the sawing clamping assembly 2 (21) press the door and window profiles against the corresponding positioning plate (15), the movable clamping base (20) moves away from the fixed clamping base (5) to a set position to leave clearance space for sawing. T05: The vertical clamping unit (8) and the horizontal clamping unit (6) of the sawing clamping assembly (12) clamp the door and window profiles to the corresponding positioning plate (15). T06: Drive the movable column (13) to move along the X direction to the sawing position, drive the lifting slide (14) to move along the Z direction to the sawing height, and drive the swing arm (16) and the sawing assembly (4) to rotate, so that the saw blade (2) rotates to the corresponding sawing angle; T07: Start the sawing assembly (4) to perform sawing. During the sawing process, the discharge assembly (22) holds the door and window profile.
