Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a high-precision CNC cutting device for aluminum alloy profiles. Background Technology

[0002] Aluminum alloy profiles are widely used in modern industrial fields such as building decoration, rail transportation, aerospace, and electronic equipment due to their excellent properties such as light weight, high strength, and good corrosion resistance. As various industries continue to increase their requirements for the precision of aluminum profile components, especially in the grooving of profile end faces in fields such as doors, windows, curtain walls, and precision frames, higher requirements are placed on their dimensional accuracy and surface quality.

[0003] Existing aluminum profile cutting equipment typically requires positioning and calibration of the profile to be processed before edge grooving. Traditional methods often rely on manual visual inspection or mechanical stops for positioning, which makes it difficult to ensure precise alignment between the profile edge and the tool path. Especially when the profile has slight bending, twisting, or burrs left over from previous processes, direct grooving can easily cause problems such as grooving position deviation and inconsistent groove depth, affecting the subsequent assembly of door and window frames. Furthermore, there are issues with chip removal during the grooving process. Aluminum alloys have high toughness, and the aluminum chips generated during grooving are small and easily stick together, clogging the grooving area and the chip groove of the tool. If they cannot be removed in a timely and effective manner, the accumulated chips will not only affect the surface quality of the grooving and accelerate tool wear, but may also cause the aluminum chips to melt due to frictional heat, or even cause processing failures.

[0023] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes the title of the high-precision CNC cutting device for aluminum alloy profiles. Please refer to [link / reference]. Figures 1-7 Specifically, it is as follows: a high-precision CNC cutting device for aluminum alloy profiles, including a conveyor table 1 and a limit frame 3; A set of slide rails is provided at the top of the conveyor table 1, and the limiting frame 3 is movably set on the top of the slide rails. The rear end of the conveyor table 1 is connected to the recycling box 2. The recycling box 2 is provided with several dust collection slots with filter plates snapped in. The recycling box 2 is connected to an external air pressure device. The front end of the limiting frame 3 is provided with an auxiliary positioning plate 4. One end of the auxiliary positioning plate 4 is connected to a telescopic shaft 41 inserted inside the limiting frame 3. The rear end of the limiting frame 3 is provided with a calibration mechanism 5 and a dust collection box 6. The calibration mechanism 5 includes a calibration plate 54 and several calibration end blocks 55 for calibrating and positioning the aluminum alloy profile. The dust collection box 6 is located at the bottom of the aluminum alloy profile for assisting in the recycling of small debris. Through the monitoring module and the rotatable calibration end blocks, the profile is dynamically corrected in real time to ensure processing accuracy. The cone-shaped recycling box, together with the dust collection box, completes the classification and recycling of debris of different sizes, which is environmentally friendly and efficient. The flexible clamping structure ensures stable clamping while allowing calibration and adjustment to prevent profile deformation. The intelligent feedback system can automatically adjust the feed and screen out defective products, reducing manual intervention. At the same time, the integrated grinding plate grinds the edges to remove burrs and improve the cut quality. Overall, it significantly improves cutting accuracy, automation, and environmental performance, and reduces maintenance frequency and rework rate.

[0026] like Figure 2 and Figure 3 As shown, the recycling bin 2 is equipped with several drive shafts, and a cutting disc 21 is installed at the top of the drive shaft for cutting and grooving the edges of aluminum alloy profiles. The bottom of the recycling bin 2 is set in a truncated cone shape for auxiliary flow of debris. In conjunction with the dust collection trough, during the feeding process of the aluminum alloy profile driven by the limit frame 3, the edges of the profile can be grooved with the help of several cutting discs 21. At this time, the external air pressure equipment is running, which can guide the discharged debris along the truncated cone at the bottom and discharge large particles of debris along the dust collection trough for subsequent unified processing.

[0027] like Figure 4As shown, the limiting frame 3 is divided into an upper fixed plate and a lower fixed plate, and several support shafts are set between the upper fixed plate and the lower fixed plate. A monitoring module 32 is set on the limiting frame 3. The monitoring module 32 has a camera installed inside and is installed inside the upper fixed plate. With the help of the camera, the position of the aluminum alloy profile can be monitored in real time. Several calibration lines 31 are set on the lower fixed plate to cooperate with the monitoring module 32 to provide feedback on the position of the aluminum alloy profile. The internal processor controls the rotation of the calibration end block 55 to assist in correction. The calibration lines 31 work with the monitoring module 32 to judge the position of the aluminum alloy profile, which can reduce the deviation of the aluminum alloy profile during the limiting process. It can also judge the curvature of the aluminum alloy profile itself, reduce bending and other situations, and screen out defective products.

[0028] like Figure 7 and Figure 9 As shown, a fixed cylinder 33 is installed at the top of the limiting frame 3. The output end of the fixed cylinder 33 passes through the upper fixed plate and a limiting pressure plate 34 is installed at the bottom. A buffer pad 341 is provided at the bottom of the limiting pressure plate 34. The fixed cylinder 33 can drive the limiting pressure plate 34 at the bottom to move. After the aluminum alloy profile is calibrated, it is limited and pressed to ensure that there will be no deviation during the subsequent cutting process.

[0029] like Figure 9 and Figure 10 As shown, the auxiliary positioning plate 4 is provided with several transmission plates 45 on the side near the limit frame 3. The transmission plates 45 are movably locked on the auxiliary positioning plate 4. One end of the transmission plate 45 is provided with several push shafts, and one end of the push shaft is connected to a locking plate 42. The locking plate 42 is provided with a resettable semi-circular shaft, and the semi-circular shaft is connected to a limit block 43. During the positioning process, the rear end of the aluminum alloy profile can be locked in the limit block 43 for auxiliary positioning. When the calibration end block 55 at the front end is rotated and adjusted, the profile can be adjusted under the cooperation of the semi-circular shaft and the movable locking plate 42, reducing the offset and tilt during the clamping process and avoiding subsequent assembly tolerance problems as much as possible.

[0030] like Figure 10 As shown, the limiting block 43 is continuously bent, and a positioning plate 44 is inserted at the top of the limiting block 43. A rubber pad is provided at the bottom of the positioning plate 44 for auxiliary pressing and limiting of the aluminum alloy profile. When the aluminum alloy profile is limited and pressed, the rubber pad at the bottom of the positioning plate 44 can be used to press against the inside of the profile to assist in positioning. The movable snap-fit ​​plate 42 and the semi-circular shaft facilitate subsequent manual adjustment of the limiting position.

[0031] like Figure 5 and Figure 8As shown, the calibration mechanism 5 also includes a connecting shaft 51, which is located inside the fixed plate on the limiting frame 3. Several feed shafts are located at the bottom of the connecting shaft 51, and a push plate 52 is connected to the bottom of each feed shaft. Locking shafts are located at both ends of the push plate 52. A limiting groove is formed on the support shaft inside the limiting frame 3, and the locking shaft is located inside the limiting groove. During the movement of the push plate 52 driven by the top feed shaft, the locking shaft can lock the plate inside the limiting groove, controlling the overall movement and reducing interference during operation. A calibration end block 55 is rotatably located at the bottom of the push plate 52. Several movable rods are located at the bottom of the calibration end block 55, and a movable frame 56 is connected to the bottom of each movable rod. A set of symmetrical calibration pressure plates 561 are provided at the bottom edge of the moving frame 56. The calibration pressure plates 561 are covered with a rubber layer. The bottom of the calibration end block 55 is connected to a fixed insertion rod 57. The bottom of the fixed insertion rod 57 is arc-shaped. During the movement of the moving frame 56, the fixed insertion rod 57 is used to push the calibration pressure plates 561 outward to abut against the inside of the aluminum alloy profile. During the positioning process, the moving frame 56 can be placed inside the aluminum alloy profile. As the fixed insertion rod 57 at the top moves, it pushes the calibration pressure plates 561 at both ends outward to abut against the inside of the aluminum alloy profile. With the help of its inner wall, it can press and position the aluminum alloy profile to ensure that it is in a relatively vertical state and reduce the occurrence of displacement. The fixed insertion rod 57 is provided with a rectangular frame, and a set of snap-fit ​​brackets 58 are connected to the outside of the rectangular frame. The snap-fit ​​brackets 58 are used to abut against the outside of the aluminum alloy profile. During the movement of the fixed insertion rod 57, the snap-fit ​​brackets 58 can also abut against the outside of the profile for calibration and limit, so that the limit pressure plate 34 can play the role of limit clamping in the future.

[0032] like Figure 5 As shown, a transmission frame 53 is provided at the front end of the push plate 52, and a calibration plate 54 is movably arranged inside the transmission frame 53. The bottom of the calibration plate 54 is provided with an arc-shaped chamfer, and the top of the calibration plate 54 is provided with a grinding plate for grinding the edge of the aluminum alloy profile. During the calibration and limiting process, the push plate 52 can be used to press against one side of the aluminum alloy profile for auxiliary calibration. Subsequently, the monitoring module 32 provides feedback on the slight angular deviation of the profile, which can be adjusted by rotating the calibration end block 55. At this time, the calibration end block 55 retracts a part, which can move the push shaft between the transmission plate 45 and the snap-fit ​​plate 42 at the rear end, and can control the amount of aluminum alloy profile pushed out. At this time, the grinding plate on the calibration plate 54 can be driven to press against the surface of the profile. During the reciprocating motion, the edge of the profile is ground to reduce burr residue and uneven cut, thereby reducing the overall rework rate.

[0033] like Figure 6As shown, a set of guide plates 61 are provided at the opening of the dust collection box 6. The guide plates 61 are inclined and used for dust and debris conduction. Several swing shafts 63 are provided inside the dust collection box 6. The swing shafts 63 are all connected to the fixed shaft, and the fixed shaft is locked inside the dust collection box 6. Several elastic suction tubes 62 are provided inside the dust collection box 6. One end of the suction tube 62 is provided with a counterweight. Both ends of the dust collection box 6 are provided with connection interfaces for connecting to external air pressure equipment. During the operation of the equipment, with the help of the external equipment, a negative pressure can be formed at the dust collection box 6, which can absorb small particles of debris generated by grinding. Larger particles of debris can fall into the recycling box 2, which can reduce the situation where small particles of debris adhere to the bottom edge of the limit frame 3 during processing, and reduce the frequency of cleaning and maintenance of the equipment.

[0034] like Figure 1 and Figure 2 As shown, one end of the conveyor table 1 is connected to a support frame, and the support frame is equipped with a control panel 11, which can control the operation of the equipment.

[0035] During use, the rear end of the aluminum alloy profile to be processed is clamped in the limiting block 43 of the auxiliary positioning plate 4. At this time, the rubber pad at the bottom of the positioning plate 44 will slightly press the inside of the profile, which plays a preliminary fixing role. The monitoring module 32 and the internal camera on the limiting frame 3 monitor the initial position and state of the profile in real time by identifying the calibration line 31 on the lower fixing plate, and determine whether there is bending or displacement. The limiting frame 3 moves on the slide rail at the top of the conveyor table 1, which drives the clamped aluminum alloy profile to feed towards the cutting area, i.e., the recycling box 2. During the feeding process, the cutting disc 21 at the top of the recycling box 2 rotates to perform high-precision cutting or grooving on the edge of the profile. Before cutting, the system performs closed-loop control. The monitoring module 32 continuously observes the position of the profile relative to the calibration line 31. If an angle or positional deviation is found, the calibration mechanism 5 is activated, the calibration end block 55 moves into the inside of the profile, and pushes the calibration pressure plate 561 outward through the fixed insertion rod 57 to press against the inner wall of the profile and restore it to a vertical state. At the same time, the snap-fit ​​bracket 58 provides auxiliary limiting from the outside. During the correction process, the snap-fit ​​plate 42 on one side of the auxiliary positioning plate 4 cooperates with the semi-circular shaft to allow the profile to have a small degree of freedom during adjustment, preventing damage to the profile or jamming due to rigid clamping. Finally, after calibration, the top fixed cylinder 33 pushes the limiting pressure plate 34 down, and the profile is firmly fixed by the buffer pad 341 to ensure cutting stability. If burrs need to be removed, the push plate 52 will drive the calibration plate 54 to move, so that the grinding plate at its top abuts against the edge of the profile. With the reciprocating micro-movement of the limiting frame 3, the cutting edge is ground to remove burrs and ensure a smooth cut. During cutting, large particles of waste generated fall into the bottom of the frustum-shaped recycling box 2. With the help of external air pressure equipment, they are discharged through the dust collection groove with a filter plate inside, which facilitates the unified collection of small particles of dust generated during grinding and cutting. These particles are absorbed by the dust collection box 6 located at the bottom of the profile. Under negative pressure, the dust is sucked in through the inclined guide plate 61 and the elastic dust collection pipe 62, reducing the amount of dust adhering to the equipment and reducing the maintenance frequency.
