TECHNICAL FIELD
[0001] The application relates to the field of metal material processing, in particular to a high-precision cutting device for aluminum profiles. BACKGROUND
[0002] Aluminum profile plates are widely used in the fields of building, automobile, aerospace and electronic equipment due to their light weight, high strength and easy processing. In the subsequent processing of the aluminum profile plates, cutting is a key process, and the machining precision directly affects the quality and assembly performance of products.
[0003] When aluminum fence poles are produced, the aluminum fence pole pieces need to be processed first, so the aluminum profile plates need to be pre-cut. The aluminum profile plates can have different shapes and sizes, so the precision needs to be improved by fixing and clamping according to the shape of the fence pole piece.
[0004] The existing aluminum profile plate cutting device usually has the following technical defects in the clamping link: poor clamping adaptability: the traditional clamps are mostly fixed or can only be clamped in one direction (such as only from both sides). For non-standard rectangular or aluminum profiles with special-shaped sections, the clamping stability is insufficient, and the machining precision is reduced under the action of cutting force, and even the workpiece is damaged. Low positioning accuracy: for aluminum profiles of different sizes, the clamp position needs to be adjusted manually, which is tedious and difficult to ensure accurate center positioning, affecting the consistency of batch processing. Prone to deformation: especially for aluminum fence pieces, the thickness is limited, and the rigidity is also limited, which is easy to cause the workpiece to be extruded and deformed, so that the size of the finished product deviates from the design size, and it is difficult to meet the requirements of high-precision machining.

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0020] This invention provides, for example Figures 1-13 The high-precision aluminum profile cutting device shown includes... Support component 001 includes support door 101, and the inside of support door 101 is provided with feeding and discharging equipment; The cutting adjustment assembly 002 includes a hydraulic cylinder 201, which is installed on the inner top of the support door 101.

A servo motor 207 is slidably connected inside the electric slide rail 203. The output end of the servo motor 207 is fixedly connected to a milling cutter 208 through a coupling. The bottom is fixed 003, which includes a horizontal lower box 304. Both sides of the horizontal lower box 304 are linked to a lower adjusting block 306. Both sides of the bottom of the horizontal lower box 304 are fixedly connected to a lower crossbar 309. The top of the lower crossbar 309 is fixedly connected to a vertical bar 310. Bottom fixing 2004 includes a longitudinal lower box 403, and lower movable rails 406 are fixedly connected to both sides of the longitudinal lower box 403. The lower movable rails 406 are connected to the transverse lower box 304 in a transmission connection. The top fixing component 005 includes a top plate 501, a horizontal upper box 503 slidably connected to the bottom of the top plate 501, upper crossbars 505 fixedly connected to both sides of the horizontal upper box 503, and the ends of the upper crossbars 505 slidably connected to the vertical bar 310.
[0021] In use, the user can first place the aluminum profile plate on the feeding and discharging equipment to feed it into the support door 101. Then, the first electric push rod pushes it, and the bottom fixing 003 and bottom fixing 004 are adjusted according to the size and dimensions of the aluminum profile to bring it closer to the cutting part. Then, the top electric push rod 502 is activated to drive the top fixing 005 to descend and fix and squeeze the top of the aluminum profile plate to prevent displacement. In order to reduce the possibility of deformation, the electric push rod is activated again to drive the bottom fixing 003 and bottom fixing 004 to support the bottom of the aluminum profile plate and support the cutting area. Then, the cutting adjustment assembly 002 is activated to cut it. The electrical components inside the device are all connected to the PLC controller for easy control.
[0022] The support door 101 has an internal cavity 102 through which the feeding and discharging equipment passes. The feeding and discharging equipment includes an extension plate 103, and two rotating rollers 104 are rotatably connected inside the extension plate 103. A transmission belt 105 is sleeved on the outside of the two rotating rollers 104. One of the rotating rollers 104 is driven by a motor. A dustproof plate 106 is installed on the top of the extension plate 103. An avoidance groove is opened inside the dustproof plate 106, and a dustproof cloth 107 is placed in the avoidance groove. A base 108 is installed at the bottom of the support door 101. A first electric push rod is also installed on the top of the base 108. The output end of the first electric push rod is fixedly connected to a support platform. The support platform is located directly above the lifting plate 301. A second electric push rod that pushes the lifting plate 301 up and down is installed inside the base 108. The lifting plate 301 is slidably connected to the support door 101.
[0023] During feeding, the motor is started, which drives the rotating roller 104 to rotate, thereby driving the transmission belt 105 to move and send the aluminum profile plate into the interior of the support door 101, located at the top of the support platform. Then, by starting the first electric push rod, the support platform is lifted, raising the aluminum profile plate away from the transmission belt 105, so that it is located between the lower adjusting block 306 and the upper adjusting block 507.
[0024] As a further optimization of the present invention, the cutting adjustment assembly 002 also includes an electric slide rail 203 driven by a motor, a limiting groove 204 is provided at the bottom of the rotating disk 202, the limiting groove 204 is slidably connected to the electric slide rail 203, a sliding groove 205 is provided inside the electric slide rail 203, a slider 206 is slidably connected inside the sliding groove 205, and a servo motor 207 is installed at the bottom of the slider 206. When cutting aluminum profiles, the hydraulic cylinder 201 drives the rotating disk 202 to descend, causing the milling cutter 208 to contact the aluminum profile. The starting motor drives the electric slide rail 203 to rotate, and the top of the electric slide rail 203 slides against the limiting groove 204, which supports the electric slide rail 203 and makes it more stable. The electric slide rail 203 drives the slider 206 to slide, which facilitates the adjustment of the position of the milling cutter 208. The servo motor 207 drives the milling cutter 208 to rotate, which facilitates multi-directional cutting.
[0025] In a further optimization of the above embodiment, the bottom fixed 003 includes a lifting plate 301, a horizontal motor 302 is installed on the top of the lifting plate 301, the output end of the horizontal motor 302 is fixedly connected to a horizontal lead screw 303 through a coupling, two horizontal lower boxes 304 are provided, both horizontal lower boxes 304 are threaded to the outside of the horizontal lead screw 303, the bottom of the horizontal lower box 304 is slidably connected to the lifting plate 301, a rotating block 311 is fixedly connected inside the horizontal lower box 304, a gear 312 is rotatably connected to the top of the rotating block 311, a rack 313 is meshed on both sides of the gear 312, a sliding plate 314 is fixedly connected to the outside of the rack 313, an movable groove 315 is opened inside the sliding plate 314 and is slidably connected to the sliding plate 314, and a horizontal downward adjustment rod 305 is fixedly connected to the outside of the sliding plate 314 through the movable groove 315. There are four lower adjustment blocks 306, which are slidably connected to the four lower adjustment blocks 306 respectively. The lower adjustment block 306 has an elliptical groove 307 inside for the horizontal lower adjustment rod 305 to move. The outer side of the horizontal lower adjustment rod 305 is connected to the lower movable block 308.
[0026] When adjustments are needed based on the lateral dimensions of the aluminum profile sheet, the user activates the lateral motor 302, which drives the lateral lead screw 303 to rotate. The lateral lead screw 303 is a bidirectional threaded screw that can drive the two lateral lower boxes 304 to move closer together. The lateral lower boxes 304 slide on the top of the lifting plate 301, which facilitates limiting the lateral lower boxes 304 and improving their stability. The lateral lower boxes 304 drive the lower horizontal bar 309 and the vertical bar 310 to slide inward. The vertical bar 310 drives the lateral upper box 503 to move closer together through the upper horizontal bar 505, thereby linking with the top fixing part 005. The lateral lower boxes 304 can also drive the lateral lower adjusting rod 305 to move synchronously. The lateral lower adjusting rod 305 drives the lower adjusting block 306 to slide on the longitudinal lower adjusting rod 411, thereby adjusting the lateral distance of the lower adjusting block 306.
[0027] The bottom fixing element 2004 includes a longitudinal motor 401, which is installed on the top of the lifting plate 301. The output end of the longitudinal motor 401 is fixedly connected to a longitudinal lead screw 404 via a coupling. Two lower C-shaped plates 402 are threadedly connected to the outer side of the longitudinal lead screw 404. Two longitudinal lower boxes 403 are slidably connected inside the lower C-shaped plates 402. A strip groove 405 is provided on the top of the lifting plate 301 for the lower C-shaped plates 402 to slide. Lower movable rails 406 are fixedly connected to both sides of the longitudinal lower boxes 403. The lower movable rails 406 are slidably connected to the lower movable blocks 308. The interior of the longitudinal lower box 403 is provided with a clearance groove 409 for the lower C-shaped plate 402 to move. The interior of the longitudinal lower box 403 is fixedly connected with a rotating block 407. The top of the rotating block 407 is rotatably connected with a gear 408. The two sides of the gear 408 are meshed with racks 410. The racks 410 are slidably connected to the longitudinal lower box 403. The top of each rack 410 is fixedly connected with a longitudinal downward adjustment rod 411. The interior of the lower adjustment block 306 is provided with a circular groove 412 for the longitudinal downward adjustment rod 411 to pass through. The top of each lower adjustment block 306 is fixedly connected with a pressing block 413.
[0028] When adjustments are needed based on the longitudinal dimensions of the aluminum profile plate, the longitudinal motor 401 is started to drive the longitudinal lead screw 404 to rotate. The longitudinal lead screw 404 is a bidirectional threaded lead screw, which can drive the two lower C-shaped plates 402 to move closer to each other. The protrusion at the bottom of the lower C-shaped plate 402 slides inside the strip groove 405, which facilitates the limiting of the lower C-shaped plate 402 and improves stability. The longitudinal lower box 403 drives the lower movable rail 406 and the longitudinal lower adjusting rod 411 to move closer to each other. The lower movable rail 406 and the longitudinal lower adjusting rod 411 drive the lower adjusting block 306 to move closer to each other, thereby adjusting the longitudinal distance between the lower adjusting block 306 and the pressing block 413. The lower C-shaped plate 402 drives the longitudinal upper box 510 to move closer to each other through the upright plate 508, and is linked with the top fixing part 005. It can automatically adjust the clamping position according to the specific size of the aluminum profile, ensuring that the clamping force is applied to the optimal force point. This not only avoids workpiece deformation caused by improper clamping position, but also ensures the repeatability of positioning accuracy for each clamping, making it particularly suitable for high-precision, large-volume automated production.
[0029] When it is necessary to fix and support the aluminum profile plate, the second electric push rod is activated to drive the bottom fixing 1 003 and the bottom fixing 2 004 to rise as a whole. When the aluminum profile plate is not longitudinally flat, after one of the extrusion blocks 413 contacts the aluminum profile plate, the lifting plate 301 continues to rise. The lower adjustment block 306 at the bottom of the extrusion block 413 in contact with the aluminum profile plate remains stationary, and the lower adjustment block 306 keeps the longitudinal lower adjustment rod 411 stationary. Since the bottom of both longitudinal lower adjustment rods 411 are connected by rack 2 410, and there is gear 2 408 between the two racks 2 410, when one rack 2 410 is stationary, the other longitudinal lower adjustment rod 411 inside the longitudinal lower box 403 can be raised through gear 2 408, thereby driving the extrusion block 413 on the other side of the longitudinal lower box 403 to contact the aluminum profile plate. Similarly, when the profile plate is uneven laterally, the pressing block 413 on one side of the transverse lower box 304 contacts the aluminum profile plate first, thus fixing the lower adjusting block 306 at the bottom of the pressing block 413. The lower adjusting block 306 keeps one side of the longitudinal lower box 403 stationary. The longitudinal lower box 403 fixes the transverse lower adjusting rod 305 through the lower movable rail 406 and the lower movable block 308. When the transverse lower adjusting rod 305 fixes the sliding plate 314 and the rack 313 connected to it, since the gear 312 is provided between the two transverse lower adjusting rods 305, the other rack 313 and the sliding plate 314 will drive the transverse lower adjusting rod 305 to continue to rise. The sliding plate 314 slides against the transverse lower box 304. The moving connection facilitates limiting and improves stability. The horizontal lowering rod 305 rises, causing the lower movable block 308 to rise. The lower movable block 308, through the lower movable rail 406, causes the longitudinal lower box 403 to rise, thereby adjusting the pressing blocks 413 on both sides of the horizontal lower box 304. The elliptical groove 307 provides movement space for the horizontal lowering rod 305, and the clearance groove 409 provides movement space for the longitudinal lower box 403. The raising and lowering of the longitudinal lower box 403 will cause the lower C-shaped plate 402 to shift until the pressing block 413 at the top of the lower adjusting block 306 at the end of another horizontal lowering rod 305 contacts and is fixed to the aluminum profile plate. Therefore, all four pressing blocks 413 can contact the aluminum profile plate and provide support for it.
[0030] It can automatically make corresponding adjustments according to the different shapes of the components and fit the workpiece surface. This allows one set of equipment to handle the processing of aluminum profiles of various specifications, reducing downtime for changing fixtures and improving equipment utilization and production flexibility.
[0031] Furthermore, the top fixing component 005 includes a top plate 501, a top electric push rod 502 is installed on the top of the support door 101, the output end of the top electric push rod 502 is connected to the top plate 501, the top plate 501 is slidably connected to the support door 101, the top of the horizontal upper box 503 is fixedly connected to a T-shaped block 504 that is slidably connected to the top plate 501, both sides of the upper crossbar 505 are slidably connected to a horizontal upper adjustment rod 506, and the outer sides of the horizontal upper adjustment rod 506 are slidably connected to an upper adjustment block 507. A vertical plate 508 is fixedly connected to the outer side of the lower chamfered plate 402. An upper chamfered plate 509 is slidably connected to the top of the vertical plate 508. A longitudinal upper box 510 is slidably connected to the inside of the upper chamfered plate 509. Upper movable rails 511 are fixedly connected to both sides of the upper chamfered plate 509. Upper movable blocks 512 are slidably connected to the outer side of the upper movable rails 511. The upper movable blocks 512 are fixedly connected to the transverse upper adjusting rods 506. Longitudinal upper adjusting rods 513 are slidably connected to both sides of the bottom of the longitudinal upper box 510. The longitudinal upper adjusting rods 513 are slidably connected to the upper adjusting blocks 507.
[0032] When it is necessary to fix the top of the aluminum profile plate, the user can activate the top electric push rod 502 to drive the top plate 501 to descend. The top plate 501 drives the horizontal upper box 503 to descend. The upper U-shaped plate 509 slides inside the vertical plate 508, which makes it easy for the vertical upper box 510 to adjust its size according to the bottom fixing 2004 without affecting the descent of the vertical upper box 510. The internal structure of the horizontal upper box 503 is the same as that of the horizontal lower box 304, and the internal structure of the vertical upper box 510 is the same as that of the vertical lower box 403. Similarly, the pressing blocks 413 at the ends of the four upper adjusting blocks 507 can be driven to contact the top of the aluminum profile plate respectively. This allows the four corners of the aluminum profile plate to be pressed and fixed according to different shapes, which greatly enhances the rigidity of the workpiece during the cutting process and effectively suppresses the vibration and displacement caused by the cutting force, thus providing a basic guarantee for achieving high-precision cutting. The adaptive clamping method combined with adjustable clamping force can provide sufficient clamping force while avoiding excessive compressive stress on the aluminum profile, fundamentally reducing workpiece clamping deformation. The extrusion block 413 can support the other side of the cut, further reducing the possibility of deformation caused by workpiece cutting, and significantly improving the processing quality and first pass rate of the product.
[0033] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
