Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, and in particular to a profile end sawing and milling processing center and a working method thereof. Background Art

[0002] At present, the split processing equipment commonly used in the field of aluminum profile processing usually includes independent vertical saw blade beds and end milling machines (or sawing machines). The vertical saw blade bed is mainly composed of a fixed-angle workbench, a single-axis movable saw blade, a manual clamping device and a feeding roller. Its working principle is to achieve bevel cutting of profiles by adjusting the saw blade angle, but it is limited by the saw blade diameter and the rigidity of the clamping mechanism, and it is difficult to adapt to the processing of large-width profiles. The milling machine uses an independent three-axis movable milling head, and the profile needs to be clamped twice before processing the end face notch, which has the problems of low process connection efficiency and accumulated positioning errors.

[0003] Therefore, the problems existing in the prior art include:

[0004] The diameter of the saw blade of the traditional vertical saw bed is insufficient to meet the cutting requirements of ultra-wide profiles, and multiple changes or manual intervention are required. The profile needs to be transferred between different equipment to complete sawing and milling, resulting in repeated positioning errors and time loss, especially for the end milling process, which requires additional clamping. The fixed clamping mechanism cannot adjust the clamping position according to the size of the profile. When cutting large-sized profiles, the long overhang length can easily cause vibration, resulting in skewed cuts or increased burrs. The lack of a directional chip removal structure means that aluminum chips are easily accumulated in the processing area, which not only affects the cleanliness of the processing environment, but may also damage the transmission components of the equipment and shorten the service life of the equipment. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the embodiments of the present invention is to provide a profile end sawing and milling processing center, which can complete profile sawing, end face milling and processing of large-width, multi-angle profiles through a single device, thereby reducing equipment investment and process conversion time.

[0006] In order to achieve the above object, the embodiment of the present invention provides the following technical solutions:

[0007] A profile end sawing and milling machining center comprises a base and a vertical sawing unit, a horizontal sawing unit and a clamping unit mounted on the base; the vertical sawing unit can move in the Y direction and the Z direction relative to the base, and the saw blade of the vertical sawing unit can rotate along the Z axis; the horizontal sawing unit is located at the rear side of the vertical sawing unit in the X direction, the horizontal sawing unit can move in the X direction, the Y direction and the Z direction relative to the base, and the saw blade of the horizontal sawing unit can rotate along the Y axis; the clamping unit can move in the X direction relative to the base, and comprises a front clamping unit and a rear clamping unit respectively located at the front and rear sides of the sawing position, for clamping the profile.

[0008] The embodiment of the present invention also provides a working method for the profile end sawing and milling processing center as described above, including the following steps:

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

[0010] When cutting a right angle, if the width of the profile exceeds a predetermined value, after the vertical saw blade cuts downwards, it then performs a cut in the Y-axis direction; when cutting an oblique angle, if the width of the profile is less than the preset value, the vertical saw blade directly performs an angle cut at position one in the Y-axis; if the width of the profile 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 position of the profile width for cutting; if the width of the profile is greater than the preset value, the vertical saw blade searches for suitable positions between position three and position four in the Y-axis direction, and performs two cuts on the profile to complete the cutting. After the first cut, the profile is fed again, and the second cut is completed after the semi-section is coplanar with the vertical saw blade;

[0011] If the profile needs to be cut by the horizontal saw blade, the horizontal saw blade moves in the X, Y, and Z axes and rotates around the Y axis according to the processing requirements to complete the groove milling or Y-direction arbitrary angle cutting process on the profile end face.

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

[0013] The profile end sawing and milling processing center includes a base, a vertical sawing unit, a horizontal sawing unit, and a clamping unit. The base serves as the basic support structure of the entire device, ensuring the stable installation and operation of each component. The vertical sawing unit is responsible for sawing the profile in the vertical direction. It can move relative to the base in the Y and Z directions to adapt to the processing requirements of profiles with different sizes and positions. At the same time, the saw blade can rotate along the Z axis to achieve cutting at different angles. The horizontal sawing unit is located behind the vertical sawing unit and is mainly used for milling the profile end face or performing arbitrary angle cutting 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 to meet the diverse processing technology requirements. The clamping unit is used to stabilize the profile during processing to prevent it from shifting or shaking during processing, which affects the processing accuracy. Through this device, the cutting of 90 degrees and positive and negative arbitrary angles of large profiles with different sizes can be satisfied, and at the same time, it has the ability to mill the groove on the profile end face. Multiple processes can be completed without transferring the profile, greatly improving the processing efficiency, reducing the equipment cost and labor cost, and improving the processing accuracy and equipment reliability.

[0029] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. In addition, it should also 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] Embodiment 1

[0031] As Figure 2 shown, this embodiment proposes a profile end sawing and milling machining center, which is a new integrated sawing and milling machining center suitable for processing door and window profiles, sliding door profiles, curtain wall profiles, sliding door profiles, and sunroom aluminum profiles 1 (as Figure 1 shown). The feeding range is: width: 30 - 260 mm, length: 20 - 190 mm. It can meet the processing requirements of most profiles to be loaded onto the machine once and produce finished profile 1.

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

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

[0034] This profile end sawing and milling center adopts a modular layout. The vertical sawing unit 8 and the horizontal sawing unit 7 are distributed front and rear along the X direction to form a continuous processing area. The vertical saw blade 81 adapts to profiles 1 with different widths through Y-direction movement, and its Z-axis rotation realizes cutting at angles from -50° to 50°; the horizontal saw blade 71 covers the end face processing requirements through XYZ three-axis movement, and the Y-axis rotation function expands the notch processing angle range. The X-direction movement mechanism of the front and rear clamping units 4 is linked with the sawing unit, and dynamically adjusts the clamping position during the cutting process: the front clamping unit 2 approaches / away from the vertical saw blade 81 through servo drive to shorten the overhang of the profile 1, and the rear clamping unit 4 makes an avoidance displacement in cooperation with the processing of the horizontal saw blade 71.

[0035] A gantry 31 is provided on the base 3, and a track along the Y axis is provided on the gantry 31. 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, a rotating motor is installed on the vertical seat 82, the rotating shaft of the rotating motor is along the Z-axis direction, and the vertical saw blade 81 is installed on the lower side of the rotating motor.

[0036] The gantry 31 serves as the bearing frame of the vertical sawing unit 8, and the sliding fit between its Y-direction track and the transverse seat realizes the lateral positioning of the saw blade. The vertical seat 82 drives the saw blade to rotate around the Z axis through the rotating motor, and the angle adjustment mechanism works in coordination with the Y-direction movement: when cutting a special angle, the saw blade inclination angle generated by the rotation of the vertical seat 82 and the Y-direction displacement of the transverse seat form a composite movement trajectory.

[0037] As Figure 4 shown, an adjusting block 83 is provided on the transverse seat, a set screw is installed in the adjusting block 83, and the set screw abuts against the side surface of the vertical seat 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 seat 82, and by screwing the set screw, the vertical seat 82 is pushed to generate a small angular offset around the rotating shaft. This mechanical adjusting mechanism can compensate for the saw blade installation error and ensure the angle calibration accuracy.

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

[0039] When it is necessary to cut profiles 1 at any positive or negative angle (-50 degrees to 50 degrees), there are three cases: If the size of the profile 1 is small, the vertical saw blade 81 can directly perform angle cutting at position one in the Y-axis; if the size of the profile 1 is wide, the vertical saw blade 81 will move in the negative Y-axis direction to position two to ensure that the center of the saw blade is at the center position of the width of the profile 1, maximizing the usable range of the saw blade; if the size of the profile 1 is extremely wide and the saw blade cannot meet the requirement of cutting it off in one go, the vertical saw blade 81 can find suitable positions between position three and position four in the Y-axis direction to cut the profile 1 in two cuts. In the second and third cases, the front pressing table needs to move backward to make way for the saw blade. At the same time, in the third case, after the first cut at position three, the profile 1 needs to cooperate with the loading gripper for secondary feeding, transporting the semi-cut surface forward, and at the same time, the saw blade Y-axis moves to position four so that the saw blade of the second cut is coplanar with the semi-cut surface. Thus, the cutting is completed, and the operation for the other symmetric angle is vice versa.

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

[0041] The chip discharge groove 32 on the base 3 is used to discharge waste such as aluminum chips generated during the processing, keeping the working area clean. The fixing plate of the horizontal sawing unit 7 is installed at the position of the chip discharge groove 32, and the slide rail 73 thereon provides a moving track for the first mounting seat 76. The multi-directional sliding mounting structure enables the horizontal sawing unit 7 to flexibly adjust its position 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-direction arbitrary angle cutting, etc. Moreover, the motor and the horizontal saw blade 71 adopt a non-directly connected synchronous belt drive method, which saves space while ensuring the stability of the saw blade rotation and the transmission efficiency.

[0042] A horizontal sawing unit 7 is added to the rear end of the vertical saw blade 81. The diameter of the horizontal saw blade 71 is 450 mm. The saw blade can move in the X, Y, and Z axes. It is indirectly driven by a motor and a synchronous belt to rotate, which can meet the milling processing of the notches on the end face of the profile 1. And the saw blade can rotate 0 - 180 degrees around the rotation center B axis, enabling processing at different angles in the Y direction of the profile 1.

[0043] If there is no process that requires the horizontal saw blade 71 for processing on the profile 1, the saw blade will retract backward, and at the same time, the rear workbench 21 will move forward, and the support rollers of the auxiliary discharging unit 5 will form 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 rollers of the auxiliary discharging unit 5 will drop, the rear clamping unit 4 will vertically clamp the profile 1, and the clamping plates of the discharging gripper unit 6 will horizontally clamp the profile 1. Driven by the servo motors in the X direction of the two units, they will clamp and move the profile 1 backward together to make way for the processing area of the horizontal saw blade 71. Thus, the end face process of the profile 1 can be processed.

[0045] It can be seen that the horizontal sawing unit 7 is driven by servo motors in the X, Y, and Z axes, and the saw blade can rotate 0 - 180 degrees around the B axis. At the same time, to save space and make the structure more compact, the saw blade rotation adopts a non-direct-connected synchronous belt drive. The usage conditions of this saw blade: If the profile 1 needs end milling and grooving processing on the horizontal end face, or cutting at any angle in the Y direction, this saw blade can be directly used for processing without the need to transfer the profile 1 to a face milling machine for processing.

[0046] When the horizontal saw blade 71 is cutting, the support rollers of the auxiliary discharging unit 5 will drop to avoid, and the rear clamping unit 4 will move backward to make way for the processing area of the horizontal saw blade 71. The processing range of the horizontal saw blade 71 is as follows: 1. If there is a through straight notch process on the end face of the profile 1, this saw blade can be used to directly cut horizontally. 2. If the profile 1 needs to be cut at any angle in the Y direction (wide and short material), this saw blade can be used for cutting after rotating around the B axis. 3. If the profile 1 has a special profile 1 process that is not cut off, such as a V-shaped groove or a straight notch in the X-axis direction, this saw blade can be used for cutting after rotating around the B axis.

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

[0048] A chip guide plate 72 is installed on the fixed plate, asFigure 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 obliquely, 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 arranged on the first guide plate 721, one end of the second guide plate 722 is docked with the end of the slide rail 73, the second guide plate 722 is of an inverted V-shaped structure, and the extension line of the bottom of the inclined surface of the second guide plate 722 intersects with the first guide plate 721.

[0049] This design of the chip guide plate 72 can effectively collect and guide the chips and cutting heads generated during the processing to the chip discharger, prevent the chips from accumulating inside the equipment, affecting the processing accuracy and the normal operation of the equipment. At the same time, it is also beneficial to maintain the cleanliness of the working environment, reduce the cleaning workload and time, and improve the production efficiency.

[0050] The front clamping unit 2 includes a workbench 21, a vertical backing plate 22, a vertical pressing plate 23 and a pressing plate 24. The workbench 21 is used to support the profile 1. The vertical pressing plate 23 is pressed against the profile 1. The end faces of the workbench 21 and the vertical pressing plate 23 form a preset angle with the X direction. A pressing cylinder is arranged on the workbench 21. The pressing cylinder is parallel to the end face of the workbench 21. The pressing plate 24 is installed on the pressing cylinder and is used to press the profile 1 against the side of the vertical backing plate 22. The rear clamping unit 4 is symmetrically arranged with the front clamping unit 2.

[0051] The workbench 21 of the front clamping unit 2 is used to support the profile 1 to be processed. The vertical backing plate 22 provides a backrest support for the profile 1. The vertical pressing plate 23 is pressed against the profile 1 to prevent the profile 1 from shaking or displacing during the processing. The end faces of the workbench 21 and the vertical pressing plate 23 form a preset angle with the X direction to meet the processing requirements at different angles. By driving the pressing plate 24, the profile 1 is pressed against the side of the vertical backing plate 22 to ensure the stability of the profile 1 during the processing. The vertical pressing plate 23 adopts a two-end pressing mechanism. Facing profiles 1 with different widths, it can ensure that the vertical pressing force is evenly distributed on the profile 1 to ensure more reliable cutting. The rear clamping unit 4 (as Figure 9 shown) is symmetrically arranged with the front clamping unit 2.

[0052] A rack 33 is installed on the base 3. The rack 33 is arranged along the X direction. A gear 25 is installed on the bottom side of the workbench 21. The gear 25 meshes with the rack 33 on the base 3. The rack 33 arranged along the X direction on the base 3 and the gear 25 on the bottom side of the workbench 21 mesh with each other to form a gear-rack transmission mechanism. Through the cooperation of the gear 25 and the rack 33, the workbench 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 workbench 21 plate is 40 degrees. Within the range of the maximum width of 260 of the profile 1 on the pre-saw pressing table, parallel pressing is still carried out at an angle of 40 degrees to ensure that the horizontal pressing force can position the profile 1 parallelly at the forefront position of the saw cut. At the same time, there are reserved holes on the horizontal pressing plate 24, and different pressing jigs can be replaced according to the height and shape of different profiles 1 to meet the processing requirements of different profiles 1.

[0054] The X direction of the clamping unit is driven by a servo motor to ensure the accuracy of the moving position in the horizontal direction. When cutting normal or smaller profiles 1, the pressing table moves forward to make it as close to the saw blade as possible to shorten the overhang length during the cutting of the profile 1, thereby ensuring the cutting quality of the profile 1. When cutting large-sized profiles 1, the clamping unit moves backward to vacate the front end of the pressing table. When the saw blade is cutting at a process of -50 degrees, it can meet the cutting requirements for a larger width.

[0055] An auxiliary discharging unit 5 is also installed on the base 3, as Figure 10 shown. The auxiliary discharging unit 5 includes a fixed seat 54, a lifting seat 51, a first limit block 52 and a second limit block 53. The fixed seat 54 is installed on the base 3. The first limit block 52 is arranged at the top of the side of the fixed seat 54. The lifting seat 51 is slidably installed on the fixed seat 54 in the Z direction. The second limit block 53 is arranged at the bottom of the side of the fixed seat 54.

[0056] The auxiliary discharging unit 5 adopts a double-limit structure to limit the rising height of the lifting seat 51, so that the upper surface of the support roller is flush with the workbench 21 to form a continuous conveying surface. If the profile 1 feature has no horizontal saw blade 71 cutting process, the horizontal saw blade 71 will move backward. The rear clamping unit 4 moves forward to the saw cut of the vertical saw blade 81. At the same time, the support roller of the auxiliary discharging unit 5 will rise and be adjusted to the same height as the pressing table by using the limit block, so as to form a complete support roller channel, which can meet the one-time passing of the profile 1 and improve the processing efficiency.

[0057] A discharging gripper unit 6 is also arranged at the rear side of the base 3, as Figure 11 shown. The discharging gripper unit 6 includes a discharging frame and a discharging seat. The discharging seat is slidably installed on the discharging frame in the X direction. A fixed discharging rear support plate 62 and a sliding discharging clamping plate 61 are arranged at the bottom side of the discharging seat, and the discharging rear support plate 62 and the discharging clamping plate 61 are located above the auxiliary discharging unit 5.

[0058] The discharging gripper unit 6 is driven by a rodless magnetic coupling cylinder to slide the discharging clamping plate 61 along a linear guide rail. On the premise of meeting the gripping requirements for the width of the profile 1, the complexity of the structure is reduced, the space is more compact, and the structure is simpler. When the horizontal saw blade 71 is processing, the whole discharging seat moves backward to drive the clamped profile 1 section to vacate the processing area, and the clamping plate pressure remains constant during the movement to prevent the profile 1 from sliding.

[0059] In this embodiment, all the supporting rollers participating in the processing adopt the supporting rollers in a double-support form, such as Figure 12 shown, to avoid the inclination of the profile 1 caused by the unilateral inclination of the supporting roller cantilever, thereby improving the reliability of the equipment and greatly improving the processing accuracy.

[0060] Embodiment 2

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

[0062] Place the profile 1 on the loading device of the profile end sawing and milling processing center to make the profile 1 enter the processing area.

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

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

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

[0066] If the size of the profile 1 is small, the vertical saw blade 81 directly performs an angle cut at position one in the Y-axis.

[0067] If the size of the profile 1 is wide, the vertical saw blade 81 moves to position two in the negative Y-axis direction to make the saw blade center located at the width center position of the profile 1 to maximize the use range of the saw blade.

[0068] If the size of the profile 1 is particularly wide, the vertical saw blade 81 searches for suitable positions between position three and position four in the Y-axis direction, and the profile 1 is cut twice to complete the cutting. After the first cut, the semi-section is conveyed forward by the loading gripper, and at the same time, the saw blade moves to position four in the Y-axis to make the second saw blade coplanar with the semi-section.

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

[0070] If the profile 1 needs to be cut by the horizontal saw blade 71, the supporting rollers of the auxiliary discharging unit 5 drop, the rear clamping unit 4 vertically clamps the profile 1, the clamping plates of the discharging gripper unit 6 horizontally clamp the profile 1, and then the two move backward under the linkage of the X-direction servo motor to make room for the processing area of the horizontal saw blade 71. The horizontal saw blade 71 moves in the XYZ three axes and rotates 0-180 degrees around the B axis according to the processing requirements to complete processes such as milling the notch on the end face of the profile 1 or cutting at any angle in the Y direction.

[0071] If there are end face processes at both ends of the profile 1, first use the vertical saw blade 81 to cut the profile 1, then the clamping unit 4 and the discharging gripper unit 6 clamp the rear section of the profile 1 and move it backward to a suitable position, and then perform the processes at both ends.

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

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

[0074] Although the specific implementation manners of the present invention are described above in conjunction with the drawings, they are not limitations on the protection scope of the present invention. Those skilled in the art should understand that based on the technical solutions of the present invention, various modifications or deformations that can be made by those skilled in the art without creative efforts are still within the protection scope of the present invention.
