Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, and in particular to a profile end sawing and milling machining center and its working method. Background Technology

[0002] Currently, commonly used split-type processing equipment in the aluminum profile processing field typically includes independent vertical saw blade machines and end milling machines (or sawing machines). Vertical saw blade machines mainly consist of a fixed-angle worktable, a single-axis moving saw blade, a manual clamping device, and a feeding roller conveyor. Their working principle is to achieve beveling of the profile by adjusting the saw blade angle. However, limited by the saw blade diameter and the rigidity of the clamping mechanism, they are difficult to adapt to processing large-width profiles. Milling machines use independent three-axis moving milling heads, requiring secondary clamping of the profile before machining the end face grooves, resulting in low process connection efficiency and accumulated positioning errors.

[0003] Therefore, the problems with existing technologies include:

[0004] Traditional vertical saw blade beds suffer from insufficient blade diameter, failing to meet the cutting requirements of ultra-wide profiles and necessitating multiple blade changes or manual intervention. Profiles must be transferred between different machines for sawing and milling, leading to repetitive positioning errors and time losses, especially for end-face milling which requires additional clamping. Fixed clamping mechanisms cannot adjust the clamping position according to profile dimensions; when cutting large profiles, excessive overhang can cause vibration, resulting in skewed cuts or increased burrs. The lack of a directional chip removal structure allows aluminum chips to accumulate in the processing area, affecting the cleanliness of the processing environment and potentially damaging the equipment's transmission components, thus shortening its lifespan. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a profile end sawing and milling machining center that can complete profile sawing, end face milling, and processing of wide and multi-angle profiles with a single machine, reducing equipment investment and process changeover time.

[0006] To achieve the above objectives, the embodiments of the present invention provide the following technical solutions:

[0007] A profile end-saw milling machining center includes a base and a vertical sawing unit, a horizontal sawing unit, and a clamping unit mounted on the base. The vertical sawing unit is capable of moving relative to the base in the Y and Z directions, and the saw blade of the vertical sawing unit is capable of rotating along the Z-axis. The horizontal sawing unit is located behind the vertical sawing unit in the X direction, and the horizontal sawing unit is capable of moving relative to the base in the X, Y, and Z directions, and the saw blade of the horizontal sawing unit is capable of rotating along the Y-axis. The clamping unit is capable of moving relative to the base in the X direction and includes a front clamping unit and a rear clamping unit located at the front and rear sides of the sawing position, respectively, for clamping the profile.

[0008] This invention also provides a working method for the profile end milling machining center described above, comprising the following steps:

[0009] Adjust the position and angle of the vertical saw blade according to the size of the profile and processing requirements;

[0010] When cutting right angles, if the profile width exceeds the preset value, the vertical saw blade cuts downwards and then makes a cut along the Y-axis. When cutting beveled angles, if the profile width is less than the preset value, the vertical saw blade makes an angled cut directly at position one along the Y-axis. If the profile width is equal to the preset value, the vertical saw blade moves to position two in the negative Y-axis direction, so that the center of the vertical saw blade is located at the center of the profile width for cutting. If the profile width is greater than the preset value, the vertical saw blade finds suitable positions at positions three and four along the Y-axis and makes two cuts to complete the cut. After the first cut, the profile is fed a second time so that the half-section is coplanar with the vertical saw blade to complete the second cut.

[0011] If the profile needs to be cut by a horizontal saw blade, the horizontal saw blade will move along the XYZ axes and rotate around the Y axis according to the processing requirements to complete the groove milling or cutting process at any angle in the Y direction on the end face of the profile.

[0012] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0013] This profile end-saw milling machining center includes a base, a vertical sawing unit, a horizontal sawing unit, and a clamping unit. The base serves as the fundamental support structure for the entire equipment, ensuring the stable installation and operation of all components. The vertical sawing unit is responsible for vertical sawing of the profile. It can move relative to the base in the Y and Z directions to accommodate the processing needs of profiles of different sizes and positions. Simultaneously, the saw blade can rotate along the Z-axis to achieve cuts at different angles. The horizontal sawing unit, located behind the vertical sawing unit, is mainly used for milling the profile end face or cutting at any angle in the Y direction. It can move relative to the base in the X, Y, and Z directions, and the saw blade can rotate along the Y-axis, thus meeting diverse processing requirements. The clamping unit stabilizes the profile during processing, preventing displacement or shaking that could affect processing accuracy. This equipment can cut large profiles of different sizes at 90-degree angles and any positive or negative angle. It also has the capability to mill grooves on the end faces of profiles. Multiple processes can be completed without transferring the profiles, which greatly improves processing efficiency, reduces equipment and labor costs, and improves processing accuracy and equipment reliability.

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] Example 1

[0031] like Figure 2 As shown, this embodiment proposes a profile end sawing and milling machining center. This equipment is suitable for aluminum profiles 1 (such as those used in doors and windows, sliding doors, curtain walls, and sunrooms) Figure 1 The new integrated sawing and milling machining center (shown) has a loading range of 30-260mm in width and 20-190mm in length. It can meet the processing needs of most profiles, producing finished profile 1 in one pass.

[0032] like Figure 2 As shown, Figure 3 As shown, the profile end sawing and milling machining center includes a base 3 and a vertical sawing unit 8 mounted on the base 3 (e.g., ...). Figure 4 As shown), horizontal sawing unit 7 (as shown) Figure 5 (as shown) and clamping unit (such as Figure 7 , Figure 8 (As shown).

[0033] The vertical sawing unit 8 can move relative to the base 3 in the Y and Z directions, and the saw blade of the vertical sawing unit 8 can rotate along the Z axis; the horizontal sawing unit 7 is located behind the vertical sawing unit 8 in the X direction, and the horizontal sawing unit 7 can move relative to the base 3 in the X, Y and Z directions, and the saw blade of the horizontal sawing unit 7 can rotate along the Y axis; the clamping unit can move relative to the base 3 in the X direction, and includes a front clamping unit 2 and a rear clamping unit 4 located at the front and rear sides of the sawing position, respectively, for clamping the profile 1.

[0034] This profile end-saw milling machining center adopts a modular layout. The vertical sawing unit 8 and the horizontal sawing unit 7 are distributed along the X-axis to form a continuous processing area. The vertical saw blade 81 adapts to profiles 1 of different widths by moving in the Y-axis, and its Z-axis rotation enables cutting angles from -50° to 50°. The horizontal saw blade 71 covers the end face processing requirements by moving along the X, Y, and Z axes, and the Y-axis rotation function expands the range of groove processing angles. The X-axis movement mechanism of the front and rear clamping units 4 is linked with the sawing units, dynamically adjusting the clamping position during the cutting process: the front clamping unit 2 moves closer to / away from the vertical saw blade 81 via servo drive to shorten the overhang of the profile 1, and the rear clamping unit 4 works with the horizontal saw blade 71 to perform avoidance displacement.

[0035] The base 3 is provided with a gantry frame 31, and the gantry frame 31 is provided with a track along the Y-axis. The vertical sawing unit 8 includes a transverse seat, a vertical seat 82 and a vertical saw blade 81. The transverse seat is slidably installed on the track, the vertical seat 82 is installed on the transverse seat, and a rotary motor is installed on the vertical seat 82. The rotation axis of the rotary motor is along the Z-axis direction, and the vertical saw blade 81 is installed on the lower side of the rotary motor.

[0036] The gantry 31 serves as the supporting frame for the vertical sawing unit 8. Its Y-axis track and the sliding cooperation with the transverse seat enable the lateral positioning of the saw blade. The vertical seat 82 drives the saw blade to rotate around the Z-axis via a rotary motor. The angle adjustment mechanism works in conjunction with the Y-axis movement: when cutting at a special angle, the saw blade tilt angle generated by the rotation of the vertical seat 82 and the Y-axis displacement of the transverse seat form a composite motion trajectory.

[0037] like Figure 4 As shown, an adjusting block 83 is provided on the transverse support, and a set screw is installed in the adjusting block 83. The set screw abuts against the side of the vertical support 82. The adjusting block 83 and the set screw constitute an angle fine-tuning mechanism: the end of the set screw abuts against the side wall of the vertical support 82, and by turning the set screw, the vertical support 82 is pushed to produce a slight angular displacement around the axis of rotation. This mechanical adjustment mechanism can compensate for saw blade installation errors and ensure angle calibration accuracy.

[0038] The vertical saw blade 81 has a cutting diameter of 600mm to meet the needs of large-size cutting. To accommodate profiles 1 with different widths and heights, the vertical saw blade 81 uses a servo motor to adjust its Y-axis movement during cutting. For profiles 1 with a larger width, when cutting at 90 degrees, the vertical cut is performed downwards first, followed by a Y-axis cut to ensure that the profile 1 can be cut through.

[0039] There are three scenarios for cutting profile 1 at any angle (-50 degrees to 50 degrees): If profile 1 is small, the vertical saw blade 81 can directly cut at position one along the Y-axis. If profile 1 is wide, the vertical saw blade 81 will move to position two along the negative Y-axis to ensure the saw blade center is at the center of profile 1's width, maximizing the saw blade's usable range. If profile 1 is exceptionally wide, the saw blade cannot complete a single cut; the vertical saw blade 81 can find suitable positions three and four along the Y-axis to cut profile 1 in two stages. In the second and third scenarios, the front clamping table needs to move backward to allow the saw blade to pass. In the third scenario, after the first cut at position three, profile 1 needs to be fed a second time with the feeding gripper to convey the half-section forward. Simultaneously, the saw blade moves to position four along the Y-axis, making the second cut coplanar with the half-section. This completes the cut. The other symmetrical angle is operated in reverse.

[0040] The base 3 has a chip removal groove 32. The horizontal sawing unit 7 includes a fixed plate, a first mounting base 76, a second mounting base 77, a third mounting base 75, a support arm 74, and a horizontal saw blade 71. The fixed plate is installed at the chip removal groove 32 of the base 3. The fixed plate has a slide rail 73. The first mounting base 76 is installed on the slide rail 73. The second mounting base 77 is slidably installed on the first mounting base 76 along the Z direction. The third mounting base 75 is slidably installed on the second mounting base 77 along the Y direction. The support arm 74 is installed on the front side of the third mounting base 75. The horizontal saw blade 71 is installed on the support arm 74.

[0041] The chip removal groove 32 on the base 3 is used to remove aluminum chips and other waste generated during processing, keeping the working area clean. The fixing plate of the horizontal sawing unit 7 is installed at the chip removal groove 32, and the slide rail 73 on it provides a moving track for the first mounting seat 76. The multi-directional sliding mounting structure allows the horizontal sawing unit 7 to be flexibly adjusted in three-dimensional space. The support arm 74 is installed on the front side of the third mounting seat 75, and the horizontal saw blade 71 is installed on the support arm 74. Through the coordinated movement of each mounting seat, the horizontal saw blade 71 can reach the required spatial position to perform precise end face processing on the profile 1, meeting different process requirements, such as end face milling, Y-axis arbitrary angle cutting, etc. Moreover, the motor and the horizontal saw blade 71 adopt a non-direct connection synchronous belt drive, which saves space while ensuring the stability of the saw blade rotation and transmission efficiency.

[0042] The device adds a horizontal sawing unit 7 at the rear end of the vertical saw blade 81. The horizontal saw blade 71 has a diameter of 450mm and can move along the XYZ axes. It is indirectly driven by a motor and a synchronous belt to rotate and can perform milling of the groove on the end face of the profile 1. The saw blade can rotate 0-180 degrees with the rotation center B axis, and can process different angles in the Y direction of the profile 1.

[0043] If there is no process in the profile 1 that requires the horizontal saw blade 71 to process, the saw blade will move backward to avoid it, and at the same time the rear worktable 21 will move forward to assist the discharge unit 5 in supporting the rollers, forming a normal vertical unit profile 1 cutting mechanism.

[0044] If the profile 1 needs to be cut by the horizontal saw blade 71, the support roller of the auxiliary discharge unit 5 will drop, the rear clamping unit 4 will vertically press the profile 1, and the clamping plate of the discharge gripper unit 6 will horizontally clamp the profile 1. Under the linkage of the servo motors in the X direction, the two units will clamp the profile 1 together and move it backward to make room for the processing area of ​​the horizontal saw blade 71. Thus, the end face of the profile 1 can be processed.

[0045] As can be seen, the horizontal sawing unit 7 is driven by an XYZ three-axis servo motor, and the saw blade can rotate 0-180 degrees around the B-axis. Meanwhile, to save space and make the structure more compact, the saw blade rotation uses a non-direct-drive synchronous belt drive. The saw blade can be used as follows: if profile 1 needs to be end-milled and grouted on its horizontal end face, or cut at any angle in the Y-axis, this saw blade can be used directly for processing, eliminating the need to transfer profile 1 to an end-mill for further processing.

[0046] When the horizontal saw blade 71 is cutting, the support roller of the auxiliary discharge unit 5 will drop down to avoid it, and the rear clamping unit 4 will move backward to make room for the processing area of ​​the horizontal saw blade 71. The processing range of the horizontal saw blade 71 is as follows: 1. If the end face of the profile 1 has a through-type straight groove, the saw blade can be used to cut directly horizontally. 2. If the profile 1 needs to be cut at any angle in the Y direction (wide and short material), the saw blade can be used to rotate the B-axis before cutting. 3. If the profile 1 has a special non-cutting profile 1 process, such as a V-groove or straight groove in the X-axis direction, the saw blade can be used to rotate the B-axis before cutting.

[0047] Note that during cutting, if both ends of profile 1 have end-face processes, the profile 1 needs to be cut off first using the vertical saw blade 81. Then, the vertical clamping of clamping unit 4 and the horizontal clamping of discharge gripper unit 6 will clamp the already cut rear section of profile 1, and the two units will move backward together to a suitable position. Then, the rear end of the first section of profile 1 and the front end of the second section of profile 1 will be processed.

[0048] A chip guide plate 72 is installed on the fixed plate, such as Figure 6 As shown, the chip guide plate 72 includes a first guide plate 721 and a second guide plate 722. The first guide plate 721 is arranged at an angle, and the bottom end of the first guide plate 721 extends to the bottom of the chip discharge groove 32. The second guide plate 722 is disposed on the first guide plate 721, and one end of the second guide plate 722 is connected to the end of the slide rail 73. The second guide plate 722 has an inverted V-shaped structure, and the bottom extension line of the inclined surface of the second guide plate 722 intersects with the first guide plate 721.

[0049] The design of this chip guide plate 72 can effectively collect and guide the chips and cutting heads generated during the processing to the chip conveyor, preventing chips from accumulating inside the equipment, affecting processing accuracy and normal equipment operation. At the same time, it is also conducive to maintaining a clean working environment, reducing cleaning workload and time, and improving production efficiency.

[0050] The front clamping unit 2 includes a worktable 21, a vertical backing plate 22, a vertical pressure plate 23, and a clamping plate 24. The worktable 21 is used to support the profile 1. The vertical pressure plate 23 is pressed onto the profile 1. The end faces of the worktable 21 and the vertical pressure plate 23 are at a preset angle to the X direction. A clamping cylinder is provided on the worktable 21. The clamping cylinder is parallel to the end face of the worktable 21. The clamping plate 24 is installed on the clamping cylinder and is used to clamp the profile 1 onto the side of the vertical backing plate 22. The rear clamping unit 4 is symmetrically arranged with the front clamping unit 2.

[0051] The worktable 21 of the front clamping unit 2 supports the profile 1 to be processed. The vertical backrest 22 provides back support for the profile 1, and the vertical pressure plate 23 presses against the profile 1 to prevent it from shaking or shifting during processing. The end faces of the worktable 21 and the vertical pressure plate 23 are at a preset angle to the X direction to accommodate processing requirements at different angles. The profile 1 is pressed against the side of the vertical backrest 22 by driving the pressure plate 24, ensuring the stability of the profile 1 during processing. The vertical pressure plate 23 adopts a two-end clamping mechanism, which can ensure that the vertical clamping force is evenly distributed on the profile 1 for profiles of different widths, ensuring more reliable cutting. The rear clamping unit 4 (e.g.) Figure 9 (As shown) is arranged symmetrically with the front clamping unit 2.

[0052] A rack 33 is mounted on the base 3, and the rack 33 is arranged along the X direction. A gear 25 is mounted on the bottom side of the worktable 21, and the gear 25 meshes with the rack 33 on the base 3. The rack 33 arranged along the X direction on the base 3 meshes with the gear 25 on the bottom side of the worktable 21, forming a gear 25 rack 33 transmission mechanism. Through the cooperation of the gear 25 and the rack 33, the worktable 21 can be driven to move along the X direction, thereby driving the front clamping unit 2 to adjust its position on the base 3.

[0053] The maximum working angle of the front and rear sawing worktables 21 is 40 degrees. Within the maximum width range of the profile 1 (260mm), the pre-saw clamping table maintains a parallel clamping angle of 40 degrees to ensure that the horizontal clamping force can position the profile 1 at the foremost position of the saw cut. Simultaneously, the horizontal clamping plate 24 has pre-drilled holes, allowing for the replacement of different clamping fixtures according to the height and shape of different profiles 1, thus meeting the processing requirements of different profiles 1.

[0054] The clamping unit is driven by a servo motor in the X direction to ensure accurate horizontal movement. When cutting normal or smaller profiles 1, the clamping table moves forward to get as close as possible to the saw blade to shorten the overhang length of profile 1 during cutting, thus ensuring the cutting quality of profile 1. When cutting larger profiles 1, the clamping unit moves backward, allowing the front end of the clamping table to be cleared, enabling the saw blade to meet the cutting requirements of wider widths when cutting at -50 degrees.

[0055] An auxiliary discharge unit 5 is also installed on the base 3, such as Figure 10 As shown, the auxiliary discharge unit 5 includes a fixed seat 54, a lifting seat 51, a first limiting block 52, and a second limiting block 53. The fixed seat 54 is mounted on the base 3. The first limiting block 52 is provided on the top side of the fixed seat 54. The lifting seat 51 is slidably mounted on the fixed seat 54 along the Z direction. The second limiting block 53 is provided on the bottom side of the fixed seat 54.

[0056] The auxiliary discharge unit 5 adopts a double-limiting structure to limit the lifting height of the lifting seat 51, so that the upper surface of the support roller is flush with the worktable 21 to form a continuous conveying surface. If the profile 1 does not have a horizontal saw blade 71 cutting process, the horizontal saw blade 71 will move backward to avoid it. The rear clamping unit 4 moves forward to the sawing edge of the vertical saw blade 81, and at the same time, the support roller of the auxiliary discharge unit 5 will rise and be adjusted to the same height as the clamping table using the limiting block, thus forming a complete support roller channel, which can meet the requirement of profile 1 passing through in one go and improve processing efficiency.

[0057] The rear side of the base 3 is also provided with a discharge gripper unit 6, such as Figure 11 As shown, the discharge gripper unit 6 includes a discharge frame and a discharge seat. The discharge seat is slidably mounted on the discharge frame along the X direction. The bottom side of the discharge seat is provided with a fixed discharge back plate 62 and a sliding discharge clamping plate 61, and the discharge back plate 62 and the discharge clamping plate 61 are located on the upper side of the auxiliary discharge unit 5.

[0058] The discharge gripper unit 6 uses a rodless magnetic coupling cylinder to drive the discharge clamping plate 61 to slide along a linear guide rail. While meeting the requirements for gripping the width of the profile 1, it reduces the complexity of the structure, making the space more compact and the structure simpler. When processing with the horizontal saw blade 71, the discharge seat moves backward as a whole, causing the clamped section of the profile 1 to move out of the processing area. During the movement, the pressure of the clamping plate remains constant to prevent the profile 1 from sliding.

[0059] In this embodiment, all support rollers involved in the processing are double-supported rollers, such as... Figure 12 As shown, this avoids the tilting of profile 1 caused by the unilateral tilting of the support roller cantilever, thereby improving the reliability of the equipment and greatly improving the processing accuracy.

[0060] Example 2

[0061] This embodiment proposes a working method for a profile end milling machining center as described in Embodiment 1, including the following steps:

[0062] The profile 1 is placed on the loading device of the profile end milling machining center, so that the profile 1 enters the machining area.

[0063] According to the size and processing requirements of profile 1, the position and angle of vertical saw blade 81 are adjusted. Vertical saw blade 81 can be adjusted within the range of -50 degrees to 50 degrees to meet the cutting requirements of different angles.

[0064] For profile 1 with a larger width, when cutting at 90 degrees, the vertical saw blade 81 cuts downwards and then cuts in the Y-axis direction to ensure that profile 1 can be completely cut off.

[0065] When it is necessary to cut profile 1 at any positive or negative angle, different cutting strategies are adopted according to the dimensions of profile 1:

[0066] If the profile 1 is small, the vertical saw blade 81 can be used to cut at an angle directly at position 1 along the Y axis.

[0067] If profile 1 is wide, the vertical saw blade 81 is moved to position two in the negative Y-axis direction so that the center of the saw blade is located at the center of the width of profile 1, thereby maximizing the usable range of the saw blade.

[0068] If the profile 1 is particularly wide, the vertical saw blade 81 finds suitable positions three and four in the Y-axis direction and cuts the profile 1 twice to complete the cutting. After the first cut, the half section is conveyed forward by the feeding gripper, and at the same time the saw blade moves to position four in the Y-axis direction so that the saw blade for the second cut is coplanar with the half section.

[0069] During the cutting process, the front clamping table moves back and forth according to the size of the profile 1 to adjust the overhang length of the profile 1 and ensure the cutting quality. When cutting large-sized profile 1 or making special angle cuts, the front clamping table moves backward to make room for the saw blade.

[0070] If profile 1 needs to be cut by horizontal saw blade 71, the auxiliary discharge unit 5 supports the rollers to fall, the rear clamping unit 4 clamps the profile 1 vertically, and the clamping plate of the discharge gripper unit 6 clamps the profile 1 horizontally. Then, the two move backward under the linkage of the X-direction servo motor to make room for the processing area of ​​horizontal saw blade 71. Horizontal saw blade 71 moves along the XYZ three axes and rotates around the B-axis from 0 to 180 degrees according to the processing requirements to complete the groove milling or Y-direction arbitrary angle cutting of the end face of profile 1.

[0071] If both ends of profile 1 have end face processing, first use vertical saw blade 81 to cut profile 1, then clamping unit 4 and discharge gripper unit 6 clamp the rear section of profile 1 and move it to a suitable position, and then perform processing on both ends.

[0072] After processing, profile 1 is discharged from the processing area through auxiliary discharge unit 5.

[0073] This method can meet the processing requirements of profiles 1 with different sizes and processing requirements, improve the versatility of equipment and processing efficiency, ensure the quality and accuracy of profile 1 processing through reasonable cutting strategies and steps, and make full use of the cutting ability of the saw blade to reduce material waste and processing time.

[0074] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.

Under the linkage of the servo motor in the X-axis direction, the two units clamp the profile together and move backward to make way for the processing area of ​​the horizontal saw blade, thereby processing the end face of the profile. When cutting right angles, if the profile width exceeds the predetermined value, the vertical saw blade will cut downwards and then cut in the Y-axis direction. When cutting at an angle, if the profile width is less than the preset value, the vertical saw blade directly makes an angled cut along the Y-axis at position one. If the profile width is equal to the preset value, the vertical saw blade moves in the negative Y-axis direction to position two, so that the center of the vertical saw blade is located at the center of the profile width for cutting. If the profile width is greater than the preset value, the vertical saw blade finds suitable positions at positions three and four in the Y-axis direction and makes two cuts to complete the cut. After the first cut, the profile is fed a second time so that the half-section is coplanar with the vertical saw blade to complete the second cut.
