Description

Technical Field

[0001] The present invention relates to the technical field of profile processing and manufacturing, and specifically to a multi-host sawing and milling processing unit, a machining center and a working method for curtain wall profiles. Background Art

[0002] The statements in this part only provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Compared with conventional door and window profiles, the curtain wall profiles in construction projects are larger in size and thickness to meet the requirements of wind pressure, seismic load and structural strength of high-rise buildings.

[0004] For example, the cross-sectional size of curtain wall profiles is more than 100 mm, and the wall thickness is commonly 2.5 - 12 mm, or even thicker; the cross-section of conventional door and window profiles is between 50 - 80 mm, and the wall thickness is between 1.4 - 2.0 mm.

[0005] The end face structure of curtain wall profiles is a key part to ensure their close fit with connectors, adjacent profiles or building structures. The structure of the end face is complex and may include mortise grooves, screw holes, cuts, inclined planes, etc., for bolt fixing, rubber strip installation or drainage design.

[0006] The volume, weight and complexity of the end structure of curtain wall profiles are much greater than those of conventional door and window profiles. When processing the ends of curtain wall profiles, a combination of multiple processes such as sawing, milling and stamping is generally used. Each processing process is usually performed by a separate processing host, and multiple clamping actions are required during processing to achieve transfer between multiple processing hosts.

[0007] The processing efficiency is low by the way of repeated clamping, and it is easy to cause large processing errors. Some existing technologies attempt to use multi-axis processing hosts to improve processing efficiency, but the structure of multi-axis processing hosts is complex and the processing requirements that can be met are limited.

[0016] Further, the first saw blade together with the saw blade driving mechanism rotates around the y-axis under the drive of a swing angle driving mechanism, so that the first saw blade swings between a horizontal state and a vertical state.

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanations of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0044] The following embodiments provide a multi-host sawing and milling processing unit, a machining center and a working method for curtain wall profiles. A lateral sawing and milling host and a vertical sawing and milling host are arranged between two juxtaposed gantry frames. Each host has movements in the x, y, and z directions. At the same time, the lateral sawing and milling host can swing around the y-axis, and the vertical sawing and milling host can swing around the y-axis and the z-axis, forming a cooperation mode of two groups of sawing and milling hosts with four axes + five axes, so that the curtain wall profiles can complete the required sawing and milling processing after one clamping, and can meet the processing requirements of the end structures of most curtain wall profiles and meet the processing quality requirements.

[0045] In the following embodiments, the length direction of the profile is the x-axis or the x direction, the width direction is the y-axis or the y direction, and the height direction is the z-axis or the z direction, and the three directions are perpendicular to each other.

[0046] Unless specifically specified, the "profile" mentioned in the following embodiments all refers to the "curtain wall profile", that is, an aluminum alloy profile with a cross-sectional width exceeding 100 mm and a wall thickness greater than 3 mm. For example, a typical curtain wall profile specification is: width 385 mm, height 200 mm, wall thickness 3 - 12 mm (it can be thicker).

[0047] Embodiment 1:

[0048] The multi-host sawing and milling processing unit for curtain wall profiles given in this embodiment is arranged in the profile machining center as shown in Figure 1 The machining center shown includes a base 1. A gantry A 2 and a gantry B 3 are arranged side by side on the upper surface of the base 1. A drilling and milling unit 4 is arranged outside the gantry A 2. The space between the gantry A 2 and the gantry B 3 accommodates a sawing and milling unit 5.

[0049] The profile is grasped by a mechanical gripper and fed into the Figure 1 The machining center shown in the figure performs drilling and milling processing through the drilling and milling processing unit; after the drilling and milling processing is completed, it is fed into the subsequent sawing and milling unit 5 for sawing and milling processing according to the processing requirements. After the sawing and milling is completed, the front section of the profile is taken out and unloaded by the gripper at the discharge end.

[0050] The multi-host sawing and milling processing unit for curtain wall profiles, the overall structure is as shown in Figure 2As shown, it includes at least two groups of saw-milling fixtures: the first saw-milling fixture 51 and the second saw-milling fixture 52, as well as the corresponding saw-milling processing mechanism.

[0051] The two groups of saw-milling fixtures are arranged side by side in the space between the two gantry frames and are connected to the base 1. The two groups of saw-milling fixtures clamp the profile from both vertical and horizontal directions. In the traditional method, the profile is usually clamped and fixed by horizontal clamping or vertical clamping. However, in this solution, the cross-sectional width of the curtain wall profile is larger, and the single-direction clamping method during traditional processing cannot meet the clamping force requirements during processing. Therefore, the two groups of saw-milling fixtures clamp the profile simultaneously from the horizontal and vertical directions, clamping the profile from different directions to ensure the processing quality.

[0052] As Figure 3 and Figure 4 As shown, the saw-milling processing mechanism includes the first saw-milling processing mechanism 53 and the second saw-milling processing mechanism 54. The two groups of saw-milling processing mechanisms perform saw-milling processing in the area between the two groups of saw-milling fixtures, and both groups of saw-milling processing mechanisms can move in the x, y, and z directions. Among them, the lateral saw-milling main machine in the first saw-milling processing mechanism 53 can swing around the y-axis, and the vertical saw-milling main machine in the second saw-milling processing mechanism 54 can swing around the y-axis and the z-axis, forming a cooperation mode of two groups of saw-milling main machines with four axes + five axes, so that the curtain wall profile can complete the required saw-milling processing after one clamping, which can meet the processing requirements of the end structures of most curtain wall profiles and meet the processing quality requirements.

[0053] As Figures 5 - 6 As shown, the first saw-milling processing mechanism 53 includes a base 531 connected to the upper surface of the base 1. The upper surface of the base 531 is provided with an x-direction guide rail 532, and the x-direction guide rail 532 is slidably connected to the x-direction slide plate 533. The x-direction slide plate 533 is connected to the z-direction guide rail 539 through a bracket, and the z-direction guide rail 539 is slidably connected to the z-direction slide plate 5310. The z-direction slide plate 5310 is slidably connected to the y-direction guide rail 5311, and the y-direction guide rail 5311 is arranged on the y-direction slide plate 534, and the y-direction slide plate 534 is provided with a lateral saw-milling main machine.

[0054] As a further implementation method, the lateral saw-milling main machine can move in the x, y, and z directions under the guidance of the guide rails in three directions, enabling the lateral saw-milling main machine to feed from the vertical direction of the profile to be processed (feeding along the z direction), or from the side of the profile (feeding along the y direction), or from the feeding direction of the profile (feeding along the x direction). Among them, the x-direction driving mechanism 5313 drives the x-direction slide plate 533 and the components on this slide plate to move along the x direction. The y-direction driving mechanism 535 is arranged at one end of the y-direction slide plate 534 and drives the y-direction slide plate 534 and the components on this slide plate to move along the y direction. The z-direction driving mechanism 5312 drives the z-direction slide plate 5310 and the components on this slide plate to move along the z direction.

[0055] As a further implementation, the first saw-milling mechanism 53 is spatially arranged on one side of the feeding direction of the profile to be processed. Considering the convenience of observing the processing area during processing, when the front side is used as the visual exposure area of the processing area, the first saw-milling mechanism 53 is spatially located at the rear side, facilitating the observation of the working state of the first saw-milling mechanism 53 at any time during processing.

[0056] As a further implementation, the x-direction driving mechanism 5313, the y-direction driving mechanism 535, and the z-direction driving mechanism 5312 do not limit the specific structural form. For example, it can be a ball screw structure, in which the screw is arranged in parallel with the respective corresponding guide rails, the screw is movably connected to the corresponding slider, the slider is connected to the corresponding slide plate, and the screw is driven to rotate by the respective corresponding motors to drive the slider together with the corresponding slide plate and the components on the slide plate to achieve movement in the x, y, and z directions.

[0057] As a further implementation, the side saw-milling main machine includes a first saw blade 537, and the first saw blade 537 is driven to rotate by a saw blade driving mechanism 538, and the saw blade driving mechanism 538 is used to provide power for the first saw blade 537 during sawing or saw-milling.

[0058] As a further implementation, the first saw blade 537 together with the saw blade driving mechanism 538 is driven by a swing angle driving mechanism 536 that rotates around the y-axis, and is used to drive the first saw blade 537 to rotate or swing around the y-axis, so that the first saw blade 537 can swing between the horizontal state (0°) and the vertical state (90°), and cooperate with the movement in the x, y, and z directions to process the profile using the first saw blade 537.

[0059] In this embodiment, the swing angle driving mechanism 536 is a motor, and the motor drives the first saw blade 537 together with the saw blade driving mechanism 538 to rotate around the y-axis to achieve swinging.

[0060] As Figure 3 shown, the second saw-milling mechanism 54 includes a vertical saw-milling main machine movably connected to two groups of gantry frames. Specifically: y-direction guide rails are provided at the tops of the two groups of gantry frames, the y-direction guide rails are slidably connected to the truss, an x-direction guide rail is provided on the truss, the x-direction guide rail is slidably connected to a z-direction slide plate, and the bottom end of the z-direction slide plate is movably connected to the vertical saw-milling main machine. Through the above truss and the guide rails in three directions combined with relevant driving structures or motors, the vertical saw-milling main machine is driven to move in the x, y, and z directions, enabling the vertical saw-milling main machine to feed from the vertical direction of the profile to be processed (feed from top to bottom along the z direction), or feed from the side of the profile (feed along the y direction), or feed from the feeding direction of the profile (feed along the x direction).

[0061] As Figures 7 - 8As shown in the figure, the vertical sawing and milling machine includes a Z-axis rotation drive mechanism 541 that rotates around the Z-axis. The output end of the Z-axis rotation drive mechanism 541 is connected to a bracket 542. The bottom end of the bracket 542 is movably connected to a swing arm assembly 543. A swing arm drive mechanism 545, a second saw blade 544, and a saw blade drive mechanism 546 are provided on the swing arm assembly 543.

[0062] As a further implementation method, the second saw blade 544 is driven by the saw blade drive mechanism 546 to rotate. The saw blade drive mechanism 546 is used to provide the power for the second saw blade 544 during sawing or milling.

[0063] As a further implementation method, the second saw blade 544 together with the saw blade drive mechanism 546 is driven by a swing arm drive mechanism 545 that rotates around the Y-axis. The swing arm drive mechanism 545 drives the second saw blade 544 to rotate or swing around the Y-axis through the swing arm assembly 543, so that the second saw blade 544 can swing between a horizontal state (0°) and a vertical state (90°). In cooperation with the movements in the X, Y, and Z directions, the second saw blade 544 is used to process profiles.

[0064] In this embodiment, the swing arm drive mechanism 545 is a motor. The motor drives the second saw blade 544 together with the saw blade drive mechanism 546 to rotate around the Y-axis to achieve swinging, and is used to change the direction of the cutting seam formed by the second saw blade 544 in the XOZ vertical plane.

[0065] Sawing and milling are performed in the area between two juxtaposed gantry frames. Both the first sawing and milling mechanism 53 and the second sawing and milling mechanism 54 have movements in the X, Y, and Z directions. At the same time, the first sawing and milling mechanism 53 can also swing around the Y-axis to form a four-axis processing structure, and the second sawing and milling mechanism 54 can also swing around the Y-axis and Z-axis to form a five-axis processing structure. Through the cooperation of the two groups of sawing and milling machines with four axes + five axes, the curtain wall profiles can be completed with the required sawing and milling processing after one clamping, which can meet the processing requirements of the end structures of most curtain wall profiles and meet the processing quality requirements.

[0066] It should be noted that the more axes the sawing and milling machine has, the more comprehensive the end structures of the profiles it can handle. Correspondingly, the structure of the machine is more complex, and it is more difficult to maintain the required processing accuracy, and the cost occupied by the sawing and milling machine is higher. Based on the balance between cost and processing requirements, this solution does not adopt the method of the sawing and milling machine rotating around the X-axis. Considering that the profile can be rotated around the X-axis to a convenient processing direction in advance according to specific processing requirements before being fed into the sawing and milling unit, therefore, by using the cooperation method of two groups of sawing and milling machines with four axes + five axes, it can meet the processing requirements of the end structures of most curtain wall profiles.

[0067] Embodiment 2:

[0068] The profile processing center is asFigure 1 As shown in the figure, it includes a base 1. On the upper surface of the base 1, a gantry A 2 and a gantry B 3 are arranged in parallel. A drilling and milling unit 4 is provided outside the gantry A 2. The space between the gantry A 2 and the gantry B 3 accommodates a sawing and milling unit 5, and the sawing and milling unit 5 therein is the multi-host sawing and milling processing unit for curtain wall profiles in the first embodiment.

[0069] The profile is grasped by a mechanical gripper and fed in the X direction Figure 1 into the shown machining center, and the drilling and milling processing unit is used to perform drilling and milling processing; after the drilling and milling processing is completed, the profile is fed into the sawing and milling unit 5 in the X direction for sawing and milling processing. After reaching the set position, according to the actual processing requirements and the structural requirements of the end of the profile to be processed, any group of sawing and milling processing mechanisms is controlled to perform sawing and milling processing, or the two groups of sawing and milling processing mechanisms are controlled to cooperate for sawing and milling processing.

[0070] Embodiment 3:

[0071] The working method of the multi-host sawing and milling processing unit for curtain wall profiles includes the following steps:

[0072] The profile is fed into the sawing and milling unit 5 in the X direction for sawing and milling processing. After running to the set sawing and milling processing position, the profile stops running, and the sawing and milling fixture acts to clamp the profile;

[0073] According to the profile processing requirements, the first sawing and milling processing mechanism 53 and / or the second sawing and milling processing mechanism 54 act to start sawing and milling processing;

[0074] After the sawing and milling is completed, the frontmost section of the profile is taken out and unloaded by the gripper at the discharging end.

[0075] In this embodiment, sawing and milling is performed in the area between two parallel gantries. Both the first sawing and milling processing mechanism 53 and the second sawing and milling processing mechanism 54 have movements in the x, y, and z directions. At the same time, the first sawing and milling processing mechanism 53 can also swing around the y axis to form a four-axis processing structure, and the second sawing and milling processing mechanism 54 can also swing around the y axis and the z axis to form a five-axis processing structure. Through the cooperation of two groups of sawing and milling hosts of four-axis + five-axis, the curtain wall profile can complete the required sawing and milling processing after one clamping, can meet the processing requirements of the end structures of most curtain wall profiles, and meet the processing quality requirements.

[0076] In this embodiment, "sawing and milling" includes "sawing" and "milling". "Sawing" means sawing off a part of the profile to completely separate the profile blank, which is used to quickly divide the profile blank and control the length. "Milling" means processing holes, grooves, threads, and special-shaped contours on the profile.

[0077] For example, if a narrow groove is sawed at the end of a profile, such as a narrow groove 8 mm wide and the saw blade is only 4 mm thick, two "milling" processes are required. That is, in the rotating state of the saw blade, the required "8 mm narrow groove" is obtained through two feeding actions.

[0078] In addition, "holes" and "grooves" are sometimes processed using a drill press or a milling machine according to the differences in specific processing techniques and forming shapes. For example, when a horizontal strip-shaped groove needs to be processed on the surface of a profile, a milling machine is required to achieve the processing. If an arc-shaped groove is needed, a saw-milling method is used for processing.

[0079] At the same time, "saw-milling" also includes processing the end face of the profile, such as removing burrs or protrusions on the end face and correcting the accuracy and smoothness of the sawed end face.

[0080] According to the processing requirements of different structures of the profile, the first saw-milling processing mechanism 53 and the second saw-milling processing mechanism 54 can operate jointly or separately. Taking the structure of some curtain wall profiles as an example for introduction.

[0081] When processing the end of the profile as Figure 9 shown, any one of the saw-milling processing mechanisms is used to saw the profile to obtain the end face of the profile. For example, the second saw-milling processing mechanism 54 can be used. The notched part of the end face is processed through the action of the second saw-milling processing mechanism 54, and the "milling" method introduced above can be used for processing.

[0082] When processing the end of the profile as Figure 10 shown, any one of the saw-milling processing mechanisms is used to saw the profile to obtain the end face of the profile. For example, the second saw-milling processing mechanism 54 can be used. The two notches located at the upper part of the end face are gradually saw-milled through the action of the second saw-milling processing mechanism 54 until the width of the processed notch meets the requirements. The notch located at the lower part of the end face is processed by the first saw-milling processing mechanism 53. For example, it can be processed by switching the first saw blade 537 to a 90° vertical saw through the action of the 0° horizontal first saw + swing angle drive mechanism 536.

[0083] When processing the end of the profile as Figure 11 shown, any one of the saw-milling processing mechanisms is used to saw the profile to obtain the end face of the profile. For example, the second saw-milling processing mechanism 54 can be used. The notched part of the end face is processed through the action of the second saw-milling processing mechanism 54.

[0084] When processing the end of the profile as Figure 12 shown, any one of the saw-milling processing mechanisms is used to saw the profile to obtain the end face of the profile. For example, the second saw-milling processing mechanism 54 can be used. The notched part of the end face is processed by the first saw-milling processing mechanism 53, and it can be processed by 0° horizontal first saw + 90° vertical first saw.

[0085] When processing the end of the profile asFigure 13 When machining the end of the profile shown, any set of sawing and milling mechanisms is used to saw the profile to obtain the profile end face. For example, the second sawing and milling mechanism 54 can be used, and the notched part of the end face is machined by the operation of the second sawing and milling mechanism 54.

[0086] When machining Figure 14 When machining the end of the profile shown, any set of sawing and milling mechanisms is used to saw the profile to obtain the profile end face. For example, the second sawing and milling mechanism 54 can be used. Since there is a 45° inclined plane in the notched part of the end face, it is machined by the swinging motion of the second sawing and milling mechanism 54 around the z-axis.

[0087] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
