Description

Technical Field

[0001] This utility model relates to the field of curtain wall profile processing, and in particular to a curtain wall profile sawing device and processing system. 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] A curtain wall profile processing center is provided in the related technology, including a base, with gantry A and gantry B arranged side by side on the upper surface of the base. A milling unit is provided on the outer side of gantry A. The space between gantry A and gantry B accommodates a multi-master milling and sawing processing unit for curtain wall profiles. The multi-master milling and sawing processing unit for curtain wall profiles includes at least two sets of milling and sawing fixtures arranged side by side. A first milling and sawing processing mechanism and a second milling and sawing processing mechanism are provided in the area between the two sets of milling and sawing fixtures. The profile to be processed is fed along the x-axis to achieve milling and sawing processing. Both the first milling and sawing processing mechanism and the second milling and sawing processing mechanism have linear motion strokes in the x, y, and z directions. The first milling and sawing processing mechanism has a lateral milling and sawing main unit located in the lateral space of the profile to be processed and rotates around the y-axis. The second milling and sawing processing mechanism has a vertical milling and sawing main unit located in the space above the profile to be processed and rotates around the z-axis and y-axis respectively.

[0004] However, when using the above technical solutions to process the interface grooves at the ends of the horizontal beams on the curtain wall, since the beam has an inclined drainage surface, that is, there is an angle between the drainage surface and the XOY plane of the processing center, when sawing the interface groove, the saw blade needs to perform interpolation on the Y and Z axes. Since the saw blade needs to move synchronously on the Y and Z axes, its dynamic response lag is prone to overcutting or undercutting at the beginning and end of the inclined interface groove, forming tiny steps or burrs, which affects the processing quality. At the same time, the interpolation processing has high precision requirements for the drive system, and the equipment investment cost is high. Utility Model Content

[0005] To address the technical problem in the prior art that curtain wall profile processing centers cannot cut the interface groove of the upper horizontal beam with drainage surface with high quality, this utility model provides a curtain wall profile sawing device and processing system that can ensure the processing quality of sawing the interface groove of the upper horizontal beam and ensure the connection and sealing between the upper horizontal beam and the column.

[0006] Firstly, the technical solution adopted by this utility model to solve the above-mentioned technical problems is: a curtain wall profile sawing device, including a sawing base, a sawing unit one provided on the sawing base, the sawing unit one including a column, the column being provided on the sawing base, a lifting plate being movably provided on the column along the Z direction, a rotating seat being provided on the lifting plate, the rotating seat being rotatable about the X direction as the rotation axis, a slide being movably provided on the rotating seat, the slide being movable towards and away from the profile, a sawing component one being provided at the end of the slide, the sawing component one being rotatable about the Y direction as the rotation axis.

[0007] This invention sets the rotating seat to swing around the X-axis, allowing the sawing assembly to adjust to an angle parallel to the drainage surface of the upper beam to be processed. Combined with the sawing assembly's own rotation around the Y-axis, the cutting plane of the saw blade aligns with the drainage slope when sawing the interface groove. This eliminates the need for synchronous interpolation between the Y and Z axes, reducing dynamic response deviations caused by multi-axis linkage. It helps minimize dimensional fluctuations at the start and end positions of the interface groove, improves the smoothness of the groove edge, and reduces reliance on the multi-axis linkage accuracy of the drive system. The required sawing accuracy can be achieved in a conventional single-axis feed with pre-adjusted angle processing mode, which helps control equipment manufacturing costs. Furthermore, the improved groove processing quality reduces uneven gaps during assembly of the upper beam and column, positively impacting the sealing performance of the connection.

[0008] Furthermore, the rotating seat is rotatably connected to the lifting plate, a rotary motor is hinged to the lifting plate, the rotary motor is connected to a lead screw, a lead screw nut is provided on the lead screw, a drive seat is hinged to the lead screw nut, and the drive seat is connected to the rotating seat.

[0009] This invention uses a rotary motor to drive a lead screw, and the linear displacement of the lead screw nut is converted into a thrust of the drive seat on the rotating seat, thereby realizing the stable swing of the rotating seat around the X-axis. The lead screw drive has high position resolution and repeatability, and can accurately convert the rotation angle of the rotary motor into the swing angle of the rotating seat, making it easy to precisely adjust the sawing assembly to a state parallel to the drainage surface.

[0010] Furthermore, it also includes a reinforcing column, which is disposed on the sawing base opposite to the upright column along the X direction, and a reinforcing plate is disposed between the top ends of the reinforcing column and the upright column.

[0011] This utility model forms a stable support structure on the other side of the column by strengthening the column and the top strengthening plate, which effectively improves the overall bending stiffness and torsional stiffness of the sawing unit, suppresses the elastic deformation and vibration of the column caused by the cutting force, reduces the slight shaking during the processing, and thus further improves the dimensional accuracy and edge quality of the interface groove.

[0012] Furthermore, it also includes a second sawing unit, which includes two opposing crossbeams supported above the sawing base and arranged along the Y direction. A reinforcing beam is provided between one end of the two crossbeams, and a movable beam is also provided between the two crossbeams. The movable beam is arranged along the X direction and can move along the Y direction. A lifting seat is provided on the movable beam, and a second sawing component is provided on the lifting seat. The second sawing component can rotate about the Z direction as its rotation axis.

[0013] This invention expands the processing coverage by using a second sawing unit, enabling the device to complete the processing of the inclined interface groove of the upper crossbeam with drainage surface using the first sawing unit, and to complete the conventional sawing of profile end faces or planar features using the second sawing component that can rotate around the Z-axis in a single clamping operation. This reduces profile turnover and repeated positioning errors. At the same time, the double crossbeam support structure of the moving beam, together with the reinforcing beam, improves the bending resistance of the overhanging end. When the second sawing component is subjected to radial cutting force, it can effectively suppress flexural deformation and help maintain the straightness of the sawing trajectory. The functional differentiation and collaborative operation of the two sawing units improve processing accuracy and process integration, which is conducive to shortening the processing cycle.

[0014] Furthermore, it also includes a discharge unit, which includes a discharge seat that is movably mounted on the sawing base along the X direction. The discharge seat is also provided with a discharge slide, and a clamping assembly is movably mounted on the discharge slide along the X direction.

[0015] This invention, through the cooperation of the discharge seat and the discharge clamping assembly for X-axis conveying, can directly complete fixed-length conveying and unloading after sawing, reducing collisions and repeated clamping errors, which helps to improve the cross-sectional quality and dimensional consistency of batch processing, while shortening the flow path and improving the stability of the processing cycle.

[0016] Secondly, this utility model also provides a curtain wall profile processing system, including the above-mentioned curtain wall profile sawing device, and also includes a drilling and milling device. The drilling and milling device includes a drilling and milling base, which is located on one side of the sawing base in the X direction. A gantry frame is provided on the drilling and milling base, and a drilling and milling processing unit is provided on the gantry frame.

[0017] Furthermore, the drilling and milling unit is provided in four parts, and the four drilling and milling units are respectively used to process different surfaces of the profile.

[0018] Furthermore, all four drilling and milling units are located on the same side of the gantry frame, and a drainage groove processing unit is located on the other side of the gantry frame. The drainage groove processing unit includes a movable plate, which is movably mounted on the gantry frame along the Y direction. A Z-axis plate is vertically mounted on the movable plate, and a swing seat is mounted on the Z-axis plate. The swing seat can swing about the X-axis as its rotation axis, and a milling cutter assembly is mounted on the swing seat. The milling cutter assembly is used to process the drainage groove.

[0019] This utility model integrates the drainage groove processing unit on the other side of the gantry frame, forming a functional partition with the four drilling and milling processing units on the same side. It can independently complete the drainage groove processing without interfering with the main processing area. The swinging ability of the swing seat around the X direction allows the milling cutter assembly to adapt to the tilt angle of the drainage surface of the upper beam. During the milling process, the tool axis is kept perpendicular to the drainage surface or at a set angle, ensuring the flatness and dimensional accuracy of the drainage groove wall.

[0020] Furthermore, along the profile conveying direction, clamping component one and clamping component two are sequentially arranged on the gantry frame, and clamping component three is also arranged on the drilling and milling base. Clamping component three is located on one side of clamping component two in the X direction and close to the curtain wall profile sawing device.

[0021] This utility model forms a multi-point continuous support structure by arranging clamping component one and clamping component two sequentially along the profile conveying direction and clamping component three located on the drilling and milling base. This structure can effectively suppress flexural deformation caused by excessive overhang during profile drilling, milling and sawing.

[0022] Furthermore, each of the clamping components 1, 2, and 3 includes a lower support roller that is rotatable and horizontally arranged, a fixed roller that is rotatable and vertically arranged, and a movable roller that is rotatable and movable. The movable roller is arranged parallel to the fixed roller and moves along the Y direction. The clamping components 2 and 3 also include an upper pressure roller that is lifted and rotated, and the upper pressure roller is arranged opposite to the lower support roller.

[0023] As can be seen from the above technical solutions, this utility model has the following advantages: This invention provides a curtain wall profile sawing device and processing system. By setting the rotating seat to swing around the X-axis, the sawing component can be adjusted along with the rotating seat to an angle parallel to the drainage surface of the upper beam to be processed. Combined with the rotation adjustment of the sawing component itself around the Y-axis, the cutting plane of the saw blade can be made to fit with the drainage slope when sawing the interface groove. The processing of the slope groove can be completed without relying on the synchronous interpolation motion of the Y and Z axes, reducing the dynamic response deviation caused by multi-axis linkage, helping to reduce the dimensional fluctuation of the interface groove at the beginning and end positions, improving the flatness of the groove edge, and reducing the dependence on the multi-axis linkage accuracy of the drive system. The required sawing accuracy can be achieved in the conventional single-axis feed and angle pre-adjustment processing mode. This design helps control equipment manufacturing costs, and the improved quality of the slot processing reduces uneven gaps during the assembly of the upper beam and column, thus playing a positive role in ensuring the sealing performance of the connection parts. The rotary motor drives the lead screw, and the linear displacement of the lead screw nut is converted into a thrust force from the drive seat to the rotating seat, achieving stable oscillation of the rotating seat around the X-axis. The lead screw drive has high position resolution and repeatability, accurately converting the rotation angle of the rotary motor into the oscillation angle of the rotating seat, facilitating precise adjustment of the sawing assembly to a state parallel to the drainage surface. The reinforcing column and top reinforcing plate form a stable support structure on the other side of the column, effectively improving the overall bending and torsional stiffness of the sawing unit and suppressing the effects of cutting forces. The elastic deformation and vibration of the column reduce micro-shaking during processing, thereby further improving the dimensional accuracy and edge quality of the interface groove. The second sawing unit expands the processing coverage, allowing the device to complete the processing of the upper crossbeam inclined interface groove with drainage surface using the first sawing unit, and also to complete conventional sawing of profile end faces or planar features using the second sawing component, which can rotate around the Z-axis. This reduces profile turnover and repetitive positioning errors. Simultaneously, the double crossbeam support structure of the moving beam, combined with the reinforcing beam, improves the bending resistance of the overhanging end. When the second sawing component is subjected to radial cutting force, it can effectively suppress flexural deformation, helping to maintain the straightness of the sawing trajectory. The functional differentiation and collaborative operation of the two sawing units improve processing accuracy while enhancing... The process integration is improved, which helps to shorten the processing cycle. Through the cooperation of the discharge seat and the discharge clamping component in X-axis transfer, fixed-length conveying and unloading can be completed directly after sawing, reducing collision and repeated clamping errors, which helps to improve the cross-sectional quality and the dimensional consistency of batch processing, while shortening the flow path and improving the stability of the processing cycle. The drainage groove processing unit is integrated on the other side of the gantry, forming a functional area with the four drilling and milling processing units on the same side. It can independently complete the drainage groove processing without interfering with the main processing area. The swinging ability of the swing seat around the X-axis allows the milling cutter assembly to adapt to the tilt angle of the upper beam drainage surface, keeping the tool axis perpendicular to the drainage surface or at a set angle during milling, ensuring the flatness and dimensional accuracy of the drainage groove wall.The clamping components one and two, arranged sequentially along the profile conveying direction, together with the clamping component three located on the drilling and milling base, form a multi-point continuous support structure, which can effectively suppress flexural deformation caused by excessive overhang during profile drilling, milling, and sawing.

Detailed Implementation

[0034] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model 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 utility model, 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.

[0035] Implementation Method 1 like Figures 1 to 4As shown in the figure, this specific embodiment provides a curtain wall profile sawing device, including a sawing base 1, a sawing unit 2 disposed on the sawing base 1, the sawing unit 2 including a column 18 disposed on the sawing base 1, a lifting plate 17 movably disposed on the column 18 along the Z direction, a rotating seat 43 disposed on the lifting plate 17, the rotating seat 43 being rotatable about the X direction (profile conveying direction) as the rotation axis, a slide 16 movably disposed on the rotating seat 43, the slide 16 being movable towards and away from the profile, a sawing assembly 15 disposed at the end of the slide 16, the sawing assembly 15 being capable of... The device rotates around the Y-axis (the direction perpendicular to the profile conveying direction in the horizontal plane). Specifically, the sawing base 1, serving as the supporting foundation for the entire sawing device, is integrally cast from high-strength cast iron. Its top surface is machined with a horizontal mounting reference surface for installing the sawing unit 2 and other functional units. The column 18 has a rectangular box-shaped structure, welded from steel plates, with internal reinforcing ribs to improve bending and torsional rigidity. The bottom end of the column 18 is connected to the sawing base 1 by bolts. The column 18 extends along the Z-axis (i.e., the vertical direction). The lifting plate 17 is a flat plate structure, slidingly engaging with the front side of the column 18 via a linear guide pair. The guide rails of the linear guide pair are vertical. Fixed to the column 18, the slider is fixed to the back of the lifting plate 17, allowing the lifting plate 17 to move up and down along the Z-axis. The lifting plate 17 is driven by a Z-axis drive motor through a screw and nut mechanism to achieve precise vertical position adjustment. A rotating seat 43 is provided on the lifting plate 17. The rotating seat 43 has a plate-like structure and is rotatably connected to the lifting plate 17 through a bearing seat. The rotating seat 43 can rotate around the X-axis, which is the conveying direction of the profile, i.e., the length direction of the sawing base 1. The slide ram 16 is a long strip box structure with a rectangular or square cross-section. The slide ram 16 slides with the rotating seat 43 through a linear guide pair. The ram 16 is able to move along its own axis towards and away from the profile. The movement of the ram 16 is driven by a servo motor and a lead screw and nut mechanism, ensuring precise control of the feed speed and position. The sawing assembly 15 is mounted on the end of the ram 16 facing the profile via a rotary spindle box. The sawing assembly 15 includes a saw blade spindle, a saw blade, and a drive motor. The saw blade is mounted on the spindle, and the drive motor drives the spindle to rotate via a direct drive. The rotation of the sawing assembly 15 around the Y direction is achieved by a rotary reducer located at the end of the ram 16. The rotary reducer is driven by a servo motor, which drives the spindle box to rotate around the Y-axis, thereby changing the angle of the saw blade relative to the profile.

[0036] In this embodiment, the oscillation of the rotating seat 43 around the X-axis adjusts the overall posture of the slide 16 and the sawing assembly 15 to be parallel to the inclined drainage surface of the upper crossbeam. Subsequently, the rotation of the sawing assembly 15 around the Y-axis precisely aligns the cutting plane of the saw blade with the shape of the interface groove to be processed. When the slide 16 feeds axially toward the profile, the saw blade cuts into the profile in a straight line along the inclined direction of the drainage surface, directly sawing out the inclined interface groove that meets the design requirements. During this process, the saw blade feeds in a straight line in only one direction, without the need for interpolation linkage of the Y and Z axes. This avoids the overcutting or undercutting problems caused by dynamic response lag at the beginning and end of the interpolation motion at the groove opening, significantly improving the flatness and dimensional accuracy of the interface groove edge, thereby ensuring the sealing performance of the connection part when the upper crossbeam and the column 18 are assembled. At the same time, since a high-precision multi-axis linkage control system is not required, the manufacturing cost of the equipment is also effectively controlled.

[0037] like Figures 4 to 5 As shown, in this embodiment, the rotating seat 43 is rotatably connected to the lifting plate 17. A rotary motor 21 is hinged to the lifting plate 17. The rotary motor 21 is connected to a lead screw 22. A lead screw nut 24 is provided on the lead screw nut 24. A drive seat 23 is hinged to the lead screw nut 24 and connected to the rotating seat 43. Specifically, a bearing support is provided on the lifting plate 17, and the bearing support cooperates with the connecting journal on the rotating seat 43. A rotary motor 21 is hinged to one side of the lifting plate 17. The rotary motor 21 is a servo motor, and its housing is connected to the lifting plate 17 through a hinge seat. The hinge seat allows the rotary motor 21 to swing slightly around its hinge point as the lead screw 22 swings during the driving process. The output shaft of the rotary motor 21 is connected to the lead screw 22 through a coupling. The lead screw 22 is arranged in a direction tangential to the swing direction of the rotating seat 43. When the rotary motor 21 drives the lead screw 22 to rotate, the lead screw nut 24 generates a linear displacement along the axial direction of the lead screw 22. The lead screw nut 24 is hinged to the drive seat 23. When the rotary motor 21 drives the lead screw 22 to rotate, the linear displacement of the lead screw nut 24 pushes the rotating seat 43 to swing around the X-axis through the drive seat 23, thereby realizing the precise adjustment of the angle of the rotating seat 43. The lead screw drive has extremely high transmission accuracy and repeatability, and can accurately convert the angular displacement of the rotary motor 21 into the swing angle of the rotating seat 43, ensuring that the posture of the sawing assembly 15 is accurately matched with the tilt angle of the drainage surface. In this embodiment, the rotation angle of the rotary motor 21 is preset by the control system and calculated according to the design angle of the drainage surface of the upper beam to be processed. When processing profiles of different specifications, the adjustment can be quickly completed by simply calling the corresponding angle parameters in the control system. The operation is simple and the accuracy is reliable.

[0038] like Figures 4 to 5As shown, to further improve the structural stability of the sawing unit 2 during processing, a reinforcing column 20 is also included. The reinforcing column 20 and the upright column 18 are arranged opposite each other on the sawing base 1 along the X direction. A reinforcing plate 19 is provided between the top ends of the reinforcing column 20 and the upright column 18. Specifically, the reinforcing column 20 is welded from square steel pipe or steel plate, and its height is equivalent to that of the upright column 18. Its bottom end is fixedly connected to the sawing base 1 by bolts. The reinforcing plate 19 is a rectangular steel plate. One end of the reinforcing plate 19 is fixedly connected to the top side of the upright column 18 by bolts, and the other end of the reinforcing plate 19 is fixedly connected to the top side of the reinforcing column 20 by bolts, thereby improving the structural stability of the sawing unit 2 during processing. The side of column 18 facing away from the profile forms a closed frame structure composed of reinforcing column 20, reinforcing plate 19 and sawing base 1. This frame structure significantly improves the overall bending stiffness and torsional stiffness of sawing unit 2. When sawing assembly 15 is sawing, the bending moment and torque generated by the cutting force can be transmitted to reinforcing column 20 through reinforcing plate 19, and then shared and transmitted to sawing base 1 by reinforcing column 20. This effectively suppresses the elastic deformation and vibration of column 18 under the action of cutting force, reduces the slight wobbling of saw blade during processing, and further improves the dimensional accuracy and edge quality of interface groove, especially when the cutting volume is large or the profile cross section is large.

[0039] To expand the functionality of sawing equipment and enable it to perform multiple types of sawing processes on a single machine, such as... Figures 1 to 3As shown, this sawing device also includes a second sawing unit 3, which includes two opposing crossbeams 5. The crossbeams 5 are supported above the sawing base 1 and are arranged along the Y direction. A reinforcing beam 27 is provided between one end of the two crossbeams 5. A movable beam 7 is also provided between the two crossbeams 5. The movable beam 7 is arranged along the X direction and can move along the Y direction. A lifting seat 6 is provided on the movable beam 7. A second sawing component 9 is provided on the lifting seat 6. The second sawing component 9 can rotate about the Z direction as the rotation axis. Specifically, the crossbeams 5 are long strip structures with rectangular cross sections, made of welded steel plates or shaped steel. The crossbeams 5 are arranged along the Y direction (i.e., the horizontal direction perpendicular to the material conveying direction). The bottom of the crossbeams 5 is fixedly connected to the sawing base 1 through a support column 8. The reinforcing beam 27 is arranged along the X direction and connects the same end of the two crossbeams 5. 5. The fixed connection is integrated to improve the overall rigidity and torsional resistance of the sawing unit 2 3. The moving beam 7 is set along the X direction and its two ends are respectively slidably engaged with the two crossbeams 5. The moving beam 7 is installed on the upper surface or inner side of the crossbeam 5 through the linear guide pair. The moving beam 7 can reciprocate between the two crossbeams 5 along the Y direction. The Y direction movement of the moving beam 7 is driven by a servo motor in conjunction with a gear rack mechanism or a screw nut mechanism. The lifting seat 6 is slidably engaged with the front side of the moving beam 7 through the linear guide pair and can move up and down along the Z direction. The Z direction movement of the lifting seat 6 is driven by a drive motor through a screw nut mechanism. The sawing assembly 2 9 includes a spindle motor, a saw blade and a rotation mechanism. The sawing assembly 2 9 can rotate and swing around the vertical direction. The rotation angle is realized by the servo motor. After the saw blade axis of the sawing assembly 2 9 rotates around the Z axis, it can saw the end face or side of the profile from different angles. In this embodiment, sawing unit 2 3 is mainly used to complete conventional sawing processes such as end-cutting of profiles, length-fixed sawing, and groove processing on the profile plane. During processing, the profile passes through the working area of ​​sawing unit 2 3 along the X direction, the moving beam 7 moves along the Y direction according to the sawing position, the lifting seat 6 moves along the Z direction according to the profile height, and the sawing assembly 2 9 rotates around the Z direction to the required angle. The sawing action is completed by the Z-direction feed of the lifting seat 6 or the Y-direction feed of the moving beam 7. Sawing unit 2 3 works in conjunction with sawing unit 1 2, so that the entire sawing device can complete the sawing of the end face and planar features of ordinary profiles in one clamping, and also complete the processing of the inclined interface groove of the upper crossbeam with the inclined drainage surface, reducing the turnover and repeated positioning errors of the profile between different equipment. Meanwhile, the double crossbeam 5 support structure, together with the reinforcing beam 27, enables the moving beam 7 to have high support rigidity and bending resistance when moving on the crossbeam 5. When the sawing component 2 9 is subjected to radial cutting force, it can effectively suppress flexural deformation and ensure the straightness of the sawing trajectory, thereby improving the processing accuracy while increasing the process integration and processing efficiency.

[0040] To achieve automatic unloading of the profiles after sawing, such as Figures 2 to 3As shown, this sawing device also includes a discharge unit 4, which includes a discharge seat 14. The discharge seat 14 is movably mounted on the sawing base 1 along the X direction. The discharge seat 14 is also provided with a discharge slide 11, and a clamping component 26 is movably mounted on the discharge slide 11 along the X direction. Specifically, the bottom of the discharge seat 14 is slidably engaged with the sawing base 1 via a linear guide pair. The discharge seat 14 is driven to move along the X direction by a servo motor and a lead screw and nut mechanism. The clamping component 26 is used to clamp the end of the profile during the sawing process, providing auxiliary support, suppressing the end vibration of the profile during sawing, and avoiding a decrease in the quality of the saw cut surface due to vibration. The discharge slide 11 is a long strip platform extending along the X direction. The clamping component 26 is also used to clamp the profile during the discharge process and cut the profile. The completed profile segment is pulled out from the sawing area to the discharge position. The clamping assembly 26 includes a rear positioning plate, which is movably connected to the discharge slide 11 via a guide rail slider pair and is driven by a servo motor and a gear rack mechanism. The rear positioning plate is vertically and vertically equipped with a vertical clamping block 12 and a horizontal clamping block 13 that moves in the horizontal plane. The vertical clamping block 12 and the horizontal clamping block 13 are driven by a cylinder to clamp and release the profile. The working process is as follows: Before the cutting process, the discharge seat 14 moves to the set position along the X direction according to the fixed length dimension. The clamping assembly 26 clamps the profile to provide support. After the sawing is completed, the discharge seat 14 moves in the opposite direction along the X direction to avoid the saw blade. The rear positioning plate moves in the opposite direction along the X direction to transport the cut profile segment to the unloading station. Then the profile is released to complete the discharge. The setting of the discharge unit 4 enables automatic connection between sawing and unloading actions, reducing manual intervention and damage to profiles. At the same time, the auxiliary support of the sawing clamping component 2 37 during processing helps to ensure the flatness of the cross-section and improve the consistency and cycle stability of batch processing.

[0041] like Figure 2 As shown, in this embodiment, a clamping component 5 25 is also included. The clamping component 5 25 includes a support base. The support base is disposed on the sawing base 1 and is close to the feeding end. A vertical pressure plate is driven by a cylinder to lift on the support base. A horizontal pressure plate is also driven by another cylinder on one side of the support base.

[0042] The working process of this curtain wall profile sawing device is as follows: The profile is fed into the working area of ​​the sawing device along the X direction. For profiles requiring end-to-end finishing, fixed length, or flat grooves, sawing unit 2 (3) performs the processing. The moving beam 7 moves along the Y direction according to the sawing position, and the lifting seat 6 adjusts along the Z direction according to the profile height. After the sawing assembly 2 (9) rotates around the Z direction to the required angle, the sawing is completed by the feed from the lifting seat 6 or the moving beam 7. After sawing, the material is discharged by the unloading unit 4. For upper crossbeams with inclined drainage surfaces, when it is necessary to process the inclined interface groove at the end, sawing unit 1 (2) performs the processing. In the processing, the rotating seat 43 is reset, the slide 16 rotates to a horizontal state, and the saw blade rotates to a vertical state for vertical sawing. Then, the rotary motor 21 drives the rotating seat 43 to swing around the X direction through the lead screw 22, so that the overall posture of the slide 16 and the sawing assembly 15 is adjusted to be parallel to the drainage surface. The sawing assembly 15 then rotates around the Y direction so that the cutting plane of the saw blade is aligned with the shape of the interface groove. Subsequently, the slide 16 feeds linearly along the axial direction towards the profile, and the saw blade cuts into the profile in one go along the inclined direction of the drainage surface to complete the sawing of the inclined interface groove.

[0043] Implementation Method 2 like Figure 6 As shown, this embodiment provides a curtain wall profile processing system, including the curtain wall profile sawing device of Embodiment 1, and a drilling and milling device. The drilling and milling device includes a drilling and milling base 44, which is located on one side of the sawing base 1 in the X direction. A gantry frame 28 is provided on the drilling and milling base 44, and a drilling and milling processing unit 31 is provided on the gantry frame 28. Specifically, the drilling and milling base 44 is also made of high-strength cast iron material, and its top surface has an installation reference surface and a T-slot. The gantry frame 28 is provided on the drilling and milling base 44. The gantry frame 28 is a portal frame structure, including two columns 18 and a crossbeam 5 connecting the tops of the two columns 18. The gantry frame 28 spans above the drilling and milling base 44, forming a processing channel for the profile to pass through. The drilling and milling unit 31 is installed on the gantry frame 28. The drilling and milling unit 31 is used to drill and mill various surfaces of the profile. The drilling and milling device is used to drill and mill the profile before or after sawing to form features such as mounting holes, connecting holes, and tenons. The drilling and milling base 44 is located downstream of the sawing base 1 along the profile conveying direction. That is, the drilling and milling device and the sawing device are arranged sequentially along the profile conveying direction. The profile first enters the drilling and milling device for drilling and milling, and then enters the sawing device for sawing, forming a continuous automated processing production line.

[0044] To further improve drilling and milling efficiency, enabling multiple surfaces of the profile to be machined simultaneously or rapidly in rotation, such as... Figures 6 to 8As shown, in this embodiment, four drilling and milling units 31 are provided, and the four drilling and milling units 31 are respectively used to process different surfaces of the profile. Specifically, the four drilling and milling units 31 are respectively located on the front, rear, upper, and lower sides of the gantry 28, that is, corresponding to the four sides of the profile—the front side facing the operator, the rear side away from the operator, the top surface facing upward, and the bottom surface facing downward. Each drilling and milling unit 31 has an independent electric spindle and a three-axis linear feed system, which can move independently and complete the processing tasks of its corresponding surface. The drilling and milling components in the four directions correspond to the slot processing unit one, slot processing unit two, slot processing unit three, and slot processing unit four in the applicant's prior patent with authorization announcement number CN223368741U, and all include cutter head assemblies. Multiple cutter head assemblies can move independently along the X-axis, Y-axis, and Z-axis, and can rotate at corresponding angles for processing. Their structure and working principle will not be described in detail here.

[0045] To add the function of machining drainage grooves on the drainage surface of the upper crossbeam without interfering with the four drilling and milling machining units 31, such as... Figures 7 to 8As shown, in this embodiment, all four drilling and milling processing units 31 are arranged on the same side of the gantry frame 28, and a drainage groove processing unit 29 is arranged on the other side of the gantry frame 28. Specifically, the four drilling and milling processing units 31 are all arranged on the discharge side of the gantry frame 28, and are used to process the front side, top side, bottom side and rear side of the profile, respectively. The feed end of the gantry frame 28 is left open for installing the drainage groove processing unit 29. In this way, the four drilling and milling processing units 31 and the drainage groove processing unit 29 are located on the gantry frame 28. The two sides form functional zones that are completely isolated from each other in space, avoiding mutual interference during the processing. The drainage trough processing unit 29 includes a movable plate 38, which is movably mounted on the gantry frame 28 along the Y direction. A Z-axis plate 46 is mounted on the movable plate 38 and a swing seat 39 is mounted on the Z-axis plate 46. The swing seat 39 can swing about the X-axis as the rotation axis. A milling cutter assembly 40 is mounted on the swing seat 39 and is used to process the drainage trough. Specifically, the movable plate 38 is a rectangular flat plate structure with a slider fixedly mounted on its back. A linear guide rail extending along the Y direction is fixedly mounted on the rear side of the gantry 28. The movable plate 38 is slidably mounted on the rear side of the gantry 28 through the cooperation of the slider and the guide rail. The Y-axis movement of the movable plate 38 is driven by a servo motor and a lead screw and nut mechanism. The lead screw is set along the Y direction, and the lead screw and nut are fixed on the movable plate 38. When the servo motor drives the lead screw to rotate, the movable plate 38 moves precisely along the Y direction. The Z-axis plate 46 is a flat plate structure with a slider fixedly mounted on its back. A linear guide rail extending along the Y direction is fixedly mounted on the front side of the movable plate 38. A linear guide rail extends along the Z-direction. The Z-direction plate 46 is slidably mounted on the movable plate 38 through the cooperation of the slider and the guide rail. The Z-direction lifting and lowering of the Z-direction plate 46 is driven by a servo motor and a lead screw and nut mechanism. The lead screw is set along the Z-direction, and the lead screw and nut are fixed on the Z-direction plate 46. When the servo motor drives the lead screw to rotate, the Z-direction plate 46 is precisely lifted and lowered along the Z-direction. The swing of the swing seat 39 is driven by a servo motor and a reducer. The milling cutter assembly 40 includes an electric spindle and a milling cutter mounted on the front end of the electric spindle. The electric spindle is fixedly mounted on the swing seat 39, and the axial direction of the milling cutter changes with the swing of the swing seat 39. During processing, the swing seat 39 swings according to the inclination angle of the drainage surface of the upper crossbeam, so that the axis of the milling cutter is perpendicular to the drainage surface. Then, the moving plate 38 moves along the Y direction to the set position of the drainage groove in the width direction of the profile. The Z-axis plate 46 moves along the Z direction to make the milling cutter contact the drainage surface and cut into the set depth. The electric spindle is started to drive the milling cutter to rotate. The moving plate 38 feeds slowly along the Y direction at a set speed to mill a drainage groove of set width and depth on the drainage surface.

[0046] To ensure the positioning accuracy and stability of the profile during drilling, milling, and subsequent sawing processes, and to avoid flexural deformation caused by excessive overhang of long strip profiles, such as... Figures 6 to 8As shown, in this embodiment, along the profile conveying direction, clamping component 1 30 and clamping component 2 37 are sequentially arranged on the gantry frame 28, and clamping component 32 is also arranged on the drilling and milling base 44. The clamping component 32 is located on the X-direction side of the clamping component 2 37 and is close to the curtain wall profile sawing device. Specifically, clamping component 30 is located on the input end side of the gantry 28 along the X direction, i.e., the end where the profile enters the gantry 28. Clamping component 30 is fixedly installed on the column 18 of the gantry 28 or on the drilling and milling base 44. It is used to initially clamp and position the front part of the profile when it enters the gantry 28, guiding the profile into the processing area in the correct direction. Clamping component 37 is located on the output end side of the gantry 28 along the X direction, i.e., the end where the profile leaves the gantry 28. Clamping component 37 is installed on the gantry 28. It is used to clamp the middle and rear part of the profile after it passes through the gantry 28. Together with clamping component 30, it forms a two-point support in the area of ​​the gantry 28. The base of clamping component 32 is fixedly installed on the top surface of the drilling and milling base 44 near the sawing device by bolts. The three clamping components are arranged sequentially along the X direction to form a multi-point continuous support structure along the profile conveying direction. During the processing, when one end of the profile enters the clamping component 30, the clamping component 30 clamps the profile. Then the profile continues to be conveyed forward and enters the clamping range of the clamping component 37 and the clamping component 32 in sequence. Each clamping component clamps the profile in sequence, forming multiple support points along the entire length of the profile.

[0047] To achieve effective positioning and clamping of the profiles in each clamping assembly, and to ensure that the profiles can still be smoothly conveyed along the X-axis while clamped, such as Figures 6 to 8As shown, clamping assembly 1 30, clamping assembly 2 37 and clamping assembly 32 each include a lower support roller 36 that is rotatable and horizontally arranged, a fixed roller 33 that is rotatable and vertically arranged, and a movable roller 35 that is rotatable and movable. Specifically, the lower support roller 36 is a cylindrical roller with its axis arranged horizontally along the Y direction. The lower support roller 36 is mounted in a bearing seat fixed to the clamping assembly base via rolling bearings, allowing it to rotate freely around its own axis. The lower support roller 36 supports the profile from below, bearing its weight. The height of its top generatrix is ​​consistent with the conveying plane height of the processing system, ensuring the profile remains horizontal during conveying. The fixed roller 33 is a cylindrical roller with its axis arranged vertically along the Z direction. The fixed roller 33 is mounted in a bearing seat fixed to the base or gantry 28 via rolling bearings, allowing it to rotate freely around its own axis. The fixed roller 33 positions the profile from one side of its width direction, serving as a reference for the profile in the Y direction. The moving roller 35 is a cylindrical roller with its axis arranged vertically along the Z direction. The movable roller 35 is arranged parallel to the fixed roller 33. The movable roller 35 moves along the Y direction and slides with the base through a linear guide pair. It is driven by a cylinder or hydraulic cylinder to move along the Y direction. The movable roller 35 and the fixed roller 33 are arranged opposite to each other. After the profile is placed on the clamping assembly, the movable roller 35 moves towards the fixed roller 33 under the drive of the cylinder or hydraulic cylinder, clamping the profile between the fixed roller 33 and the movable roller 35, realizing the positioning and clamping of the profile in the Y direction. The lower support roller 36, the fixed roller 33 and the movable roller 35 can all rotate freely around their own axes. Therefore, the profile can still roll and be conveyed along the X direction on the roller surface when it is clamped. It provides sufficient clamping force to constrain the position of the profile in the Y direction without hindering the feeding movement of the profile. It is very suitable for the continuous conveying and positioning needs in automated production lines. Furthermore, clamping assembly 2 37 and clamping assembly 32 also include an upper pressure roller 34 that is lifted and rotated. The upper pressure roller 34 is positioned opposite to the lower support roller 36, with its axis arranged horizontally along the Y direction. The upper pressure roller 34 is positioned above the base and connected to the base via a lifting mechanism, which is a cylinder or hydraulic cylinder. The cylinder body is fixedly mounted on the base, and the piston rod is fixedly connected to the bearing seat of the upper pressure roller 34, driving the upper pressure roller 34 to move up and down along the Z direction. The upper pressure roller 34 is positioned opposite to the lower support roller 36, that is, the upper pressure roller 34 is located directly above the lower support roller 36, and their axes are parallel. After the profile is placed on the clamping assembly, the upper pressure roller 34 moves downward under the drive of the lifting mechanism, pressing the profile against the lower support roller 36, thus achieving positioning and clamping of the profile in the Z direction. This prevents the profile from jumping up and down due to cutting forces during processing. The upper pressure roller 34 can also rotate freely around its own axis without obstructing the conveying of the profile along the X direction.

[0048] The working process of this curtain wall profile processing system is as follows: The profile is first fed into the drilling and milling device along the X-axis. The four drilling and milling processing units 31 on the gantry 28 perform drilling, milling, and tapping on the front, rear, top, and bottom surfaces of the profile, respectively. At the same time, the swing seat 39 of the drainage groove processing unit 29 on the other side of the gantry 28 swings to the corresponding posture according to the inclination angle of the drainage surface of the upper crossbeam. The moving plate 38 and the Z-axis plate 46 position the milling cutter assembly 40 on the processing position on the drainage surface. The milling cutter assembly 40 is fed along the Y-axis to mill on the drainage surface. Drainage grooves are cut out; during the drilling and milling process, clamping components 1 30, 2 37 and 3 32 clamp the profile in sequence along the profile conveying direction to form multi-point support to prevent bending deformation; after drilling and milling is completed, the profile continues to be conveyed along the X direction to the sawing device, where sawing unit 1 2 completes the sawing of the inclined interface groove at the end of the upper crossbeam, or sawing unit 2 3 completes other conventional sawing processes, and finally the finished profile is output by the discharge unit 4, realizing fully automatic continuous processing from drilling and milling to sawing.

[0049] As can be seen from the above specific embodiments, this utility model has the following beneficial effects: 1. By setting the rotating seat 43 to swing around the X-axis, the sawing assembly 15 can be adjusted to be parallel to the drainage surface. Combined with the rotation of the saw blade around the Y-axis, the cutting plane of the saw blade is made to fit with the drainage slope. The slope groove can be processed without the need for Y-axis and Z-axis interpolation linkage, avoiding the dynamic response deviation caused by multi-axis linkage, improving the flatness of the groove edge, reducing the dependence on the accuracy of multi-axis linkage, which is conducive to controlling equipment costs. Moreover, the improvement of groove processing quality can reduce uneven assembly gaps and ensure sealing performance. 2. The rotary motor 21 drives the lead screw 22 to drive the lead screw nut 24 to linear displacement, which is converted into the thrust of the drive seat 23 on the rotating seat 43 to achieve stable swing of the rotating seat 43. The lead screw drive has high position resolution and repeatability, which makes it easy to accurately adjust the sawing component 15 to be parallel to the drainage surface.

[0050] 3. By forming a support structure on the other side of the column 18 through the reinforcing column 20 and the top reinforcing plate 19, the bending and torsional stiffness of the sawing unit as a whole is improved, the deformation and vibration of the column 18 caused by the cutting force are suppressed, and the dimensional accuracy and edge quality of the interface groove are further improved.

[0051] 4. The sawing unit 23 expands the processing range, enabling the device to complete both inclined interface groove processing and conventional sawing in a single clamping operation, reducing turnover and repetitive positioning errors. The double crossbeams 5, in conjunction with the reinforcing beam 27, improve the bending resistance of the overhanging end, ensuring the straightness of the sawing trajectory, and improving process integration and processing cycle time. The X-axis transfer cooperation between the discharge seat 14 and the discharge clamping assembly enables fixed-length conveying and unloading after sawing. The clamping assembly 4 26 provides auxiliary support during processing to suppress end vibration. The discharge clamping assembly maintains a grip during transfer, reducing collisions and repetitive clamping errors, and improving cross-sectional quality and dimensional consistency.

[0052] 5. The drainage groove processing unit 29 is integrated on the other side of the gantry 28, forming a functional area with the four drilling and milling processing units 31. It can independently complete the drainage groove processing without interfering with the main processing area. The swing seat 39 swings around the X direction to make the milling cutter assembly 40 adapt to the tilt angle of the drainage surface, ensuring the flatness and dimensional accuracy of the drainage groove wall.

[0053] 6. The clamping components 1 30, 2 37 and 32 arranged sequentially along the profile conveying direction form a multi-point continuous support, which effectively suppresses the flexural deformation caused by excessive overhang during drilling, milling and sawing.
