Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a positioning and cutting structure for aluminum profile processing. Background Technology

[0002] Aluminum profiles are relatively soft and are prone to denting and deformation due to extrusion pressure during high-speed cutting. When traditional saw blades cut square aluminum profiles, the initial extrusion pressure can cause uneven cuts, affecting subsequent welding accuracy. In addition, hollow or openwork aluminum profiles, such as prismatic profiles, are prone to positional shifts due to uneven clamping force distribution, resulting in tilted cut surfaces.

[0003] Existing positioning and cutting devices for aluminum profile processing suffer from unstable clamping due to the varying sizes of the aluminum profiles being cut. Different sized aluminum profiles may not be completely fixed during clamping, leading to positional shifts or movement during cutting. This affects the accuracy of the required cutting length and angle. Furthermore, unstable clamping can cause vibrations during the cutting process, further impacting cutting quality. Additionally, the fixed structure of the cutting head in existing positioning and cutting devices makes maintenance cumbersome. This increases the complexity and difficulty of repair and maintenance. Because the cutting head is fixed, it cannot be easily disassembled and replaced, requiring tedious disassembly and readjustment when repair or replacement is needed. The existing patent (publication number: CN220196509U) discloses a positioning and cutting device for aluminum profile processing. It uses a cutting table and a positioning table in combination. During use, the operator can make corresponding adjustments according to the size of the aluminum profile. By adjusting the rotating rod, the position of the nut can be moved, allowing the limiting plate to adapt to aluminum profiles of different sizes. This ensures stable clamping of the aluminum profile during processing, solves the problem of unstable clamping caused by different sizes of aluminum profiles, which affects the cutting accuracy, and achieves the goal of ensuring cutting quality.

[0004] To address the aforementioned issues, existing patents offer solutions. However, existing positioning and cutting structures for aluminum profile processing typically lack adaptive positioning capabilities for irregularly shaped aluminum profiles. They are not convenient for flexibly adjusting the clamping angle and force according to the specific contours of the aluminum profiles, resulting in uneven distribution of clamping force. This can easily lead to problems such as aluminum profile position shift and cut surface tilt, affecting cutting accuracy and subsequent processing quality. Furthermore, it is not convenient to accurately collect the debris and dust generated during the cutting process, causing debris to accumulate on the processing table and cutting components. This can easily lead to accelerated wear of the cutting blade, obstruction of the cutting path, and affect the stability of cutting and the service life of the equipment.

[0005] To address this, a positioning and cutting structure for aluminum profile processing is proposed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 The present invention provides the following technical solution: A positioning and cutting structure for aluminum profile processing includes a processing table 1. Positioning components 4 are provided on both sides of the top of the processing table 1. A dust collection component 5 is provided on the top of the processing table 1. The positioning component 4 includes a rotating seat 401 fixedly connected to the top of the processing table 1. Rotating shafts 402 are rotatably connected to both sides of the rotating seat 401. A positioning clamping plate 403 is fixedly connected to the bottom of the rotating shaft 402. A limiting rod 404 is fixedly connected to the bottom of the positioning clamping plate 403. An arc-shaped limiting frame 405 is fixedly connected inside the processing table 1. The arc-shaped limiting frame 405 is slidably connected to the limiting rod 404. A driving cylinder 406 is fixedly connected to the top of the positioning clamping plate 403. An upper positioning seat 407 is fixedly connected to the top of the driving cylinder 406.

[0020] In this embodiment: by starting the motor inside the rotating seat 401, the motor drives the rotating shaft 402 to rotate. The rotating shafts 402 on both sides can rotate flexibly around the rotating seat 401. The positioning clamp 403 connected to the bottom of the rotating shaft 402 adjusts its angle accordingly to closely fit the contour of the irregular aluminum profile. During the rotation of the positioning clamp 403, the limiting rod 404 at its bottom slides along the arc-shaped limiting frame 405 fixed inside the processing table 1. The limiting circular plate 10 at the bottom of the limiting rod 404 plays a limiting role at the bottom of the processing table 1, ensuring that the limiting rod 404 is always in the arc. The positioning clamp 403 slides within the limiting bracket 405, ensuring a precise and stable rotation trajectory. Once the positioning clamp 403 is adjusted to a suitable position that fits against both sides of the shaped aluminum profile, the drive cylinder 406 at the top of the positioning clamp 403 is activated. The output end of the drive cylinder 406 pushes the upper positioning seat 407 downward until the upper positioning seat 407 is in close contact with the top of the shaped aluminum profile. This securely clamps the shaped aluminum profile from multiple directions, effectively preventing instability and positional shift caused by the special shape of the aluminum profile, and providing a stable positioning foundation for subsequent cutting operations.

[0021] Specifically, such as Figure 3As shown, the dust collection assembly 5 includes a support frame 501 fixedly connected to the top of the processing table 1, a reinforcing seat 502 fixedly connected to the bottom of the support frame 501, a dust collection fan 503 fixedly connected to the top of the support frame 501, and a filter dust collection chamber 504 slidably connected inside the dust collection fan 503.

[0022] Specifically, such as Figure 3 As shown, an adjusting electric cylinder 505 is fixedly connected to the top of the support frame 501, and a dust suction hood 506 is fixedly connected to the output end of the adjusting electric cylinder 505.

[0023] Specifically, such as Figure 3 As shown, a vacuum cleaner hose 507 is connected to the top of the vacuum cleaner hood 506, and the vacuum cleaner hose 507 is connected to the vacuum cleaner fan 503.

[0024] In this embodiment: When the cutting operation begins, the adjusting electric cylinder 505 on the top of the support frame 501 is activated, precisely adjusting the extension and retraction of the output end according to the cutting position, thereby moving the dust suction hood 506 to a suitable position directly above the cutting point. One end of the suction hose 507 connected to the top of the dust suction hood 506 is connected to the dust suction fan 503. After the dust suction fan 503 is started, it generates a strong negative pressure, sucking in the debris and dust generated during the cutting process through the dust suction hood 506, and then transporting it through the suction hose 507 to the filter dust collection chamber 504 inside the dust suction fan 503. The filter dust collection chamber 504 can efficiently filter and collect the sucked-in debris and dust, facilitating subsequent cleaning, avoiding pollution of the processing environment by debris and dust and harm to the health of operators, ensuring that the cutting operation is carried out in a clean environment, and improving the overall quality and safety of the processing.

[0025] Specifically, such as Figure 6 As shown, a fixed base 2 is fixedly connected to the bottom of the processing table 1, a drive motor 3 is fixedly connected to the outside of the fixed base 2, a lead screw 6 is fixedly connected to the output end of the drive motor 3, a moving block 7 is threadedly connected to the outside of the lead screw 6, a cutting frame 8 is fixedly connected to the top of the moving block 7, and a cutting blade 9 is fixedly connected inside the cutting frame 8.

[0026] Specifically, such as Figure 5 As shown, the bottom of the limiting rod 404 is fixedly connected to the limiting circular plate 10, which is located at the bottom of the processing table 1.

[0027] In this embodiment: by setting up a fixed base 2, a drive motor 3, a lead screw 6, a moving block 7, a cutting frame 8, and a cutting blade 9, when cutting the aluminum profile, the drive motor 3 is started, and its output end drives the lead screw 6 to start rotating. Since the lead screw 6 is threadedly connected to the moving block 7, the rotational motion of the lead screw 6 is converted into the linear motion of the moving block 7 along the axial direction of the lead screw 6. Then, the cutting frame 8 connected to the top of the moving block 7 moves smoothly at the bottom of the processing table 1, and the cutting blade 9 inside the cutting frame 8 also moves along with it, gradually approaching... The aluminum profile is cut and the cutting operation is completed. By setting a limiting circular plate 10, when the limiting rod 404 slides in the arc-shaped limiting frame 405, the limiting circular plate 10 can effectively block the upward movement of the limiting rod 404, prevent the limiting rod 404 from disengaging from the arc-shaped limiting frame 405, and ensure that the limiting rod 404 always slides within the preset trajectory. This ensures that the rotation trajectory of the positioning clamp 403 is stable and accurate, avoids the problem of unstable clamping of aluminum profile caused by the offset of the positioning clamp 403, and enhances the reliability of the positioning component 4 in positioning irregular aluminum profiles.

[0028] Specifically, such as Figure 4 As shown, an anti-slip pad 11 is bonded to the inner side of the positioning clamp 403. The anti-slip pad 11 is made of rubber.

[0029] Specifically, such as Figure 1 As shown, a support leg 12 is fixedly connected to the bottom of the processing table 1, and a rubber foot pad 13 is fixedly connected to the bottom of the support leg 12.

[0030] In this embodiment: by setting anti-slip pads 11, when the positioning clamp 403 contacts both sides of the irregular aluminum profile, the rubber anti-slip pads 11 bonded to the inner side of the positioning clamp 403 directly adhere to the surface of the aluminum profile. At this time, the anti-slip pads 11 tightly adhere to the surface of the aluminum profile through their own elastic deformation, increasing the friction between the positioning clamp 403 and the aluminum profile, effectively preventing the aluminum profile from sliding relative to each other due to vibration or force during the cutting process, ensuring the positional stability of the aluminum profile after positioning. Especially for the irregular surface of the irregular aluminum profile, the anti-slip pads 11 can effectively prevent the aluminum profile from sliding relative to each other during the cutting process. The adaptive deformation of the 1 improves the clamping effect and solves the problem of slippage in traditional clamping structures. By setting the support leg 12 and rubber foot pad 13, the rubber foot pad 13 at the bottom of the support leg 12 is in direct contact with the ground. During the operation of the equipment, the vibration generated by the cutting operation is transmitted to the support leg 12 through the processing table 1, and then to the ground through the rubber foot pad 13. The rubber foot pad 13 has good elasticity and cushioning performance, which can absorb and weaken the vibration energy, reduce the overall vibration amplitude of the equipment, prevent the equipment from shifting due to vibration, and improve the stability and safety of the equipment operation.

[0031] Working Principle: When using this aluminum profile processing positioning and cutting structure, the irregular aluminum profile to be processed is first placed at the positioning position on the top of the processing table 1. At this time, the positioning component 4 is activated, and then the motor inside the rotating seat 401 drives the rotating shaft 402 to rotate. Then, the rotating shafts 402 on both sides can rotate around the rotating seat 401. Then, the positioning clamp 403 connected to the bottom of the rotating shaft 402 can adjust the angle to adapt to the contour of the irregular aluminum profile. During the rotation of the positioning clamp 403, the limiting rod 404 at its bottom will slide along the arc-shaped limiting frame 405 fixed inside the processing table 1. The limiting circular plate 10 at the bottom of the limiting rod 404 plays a limiting role at the bottom of the processing table 1, preventing the limiting rod 404 from sliding off the arc-shaped limiting frame 405. 05. The positioning clamp 403 is disengaged to ensure stable and precise rotation. Once the positioning clamp 403 is adjusted to fit against both sides of the irregular aluminum profile, the drive cylinder 406 is activated. The output end of the drive cylinder 406 pushes the upper positioning seat 407 downwards until it is in close contact with the top of the irregular aluminum profile. Combined with the rubber anti-slip pad 11 adhered to the inner side of the positioning clamp 403, the irregular aluminum profile is firmly clamped from multiple directions (top, bottom, left, and right), effectively avoiding instability and positional shift caused by the special shape of the aluminum profile. This solves the problem of existing structures being inconvenient for positioning irregular aluminum profiles. After positioning the aluminum profile, the drive motor 3 is activated, and the output end of the drive motor 3 drives the lead screw 6. As the lead screw 6 rotates, its rotation is converted into linear motion of the moving block 7 due to the threaded connection between the lead screw 6 and the moving block 7. The cutting frame 8, connected to the top of the moving block 7, moves accordingly at the bottom of the processing table 1. The cutting blade 9 inside the cutting frame 8 then gradually approaches the part of the aluminum profile to be cut. During the cutting process, the dust collection assembly 5 starts simultaneously. Its support frame 501 is stably fixed to the top of the processing table 1 by the bottom reinforcing seat 502. At this time, the adjusting electric cylinder 505 is activated to adjust the extension and retraction of the output end according to the cutting position, thereby moving the dust collection hood 506 to a suitable position directly above the cutting point. One end of the dust collection hose 507 connected to the top of the dust collection hood 506 is connected to the dust collection fan 503. 3. Upon startup, negative pressure is generated, drawing in the debris and dust produced during the cutting process through the dust suction hood 506. The debris and dust are then transported via the suction hose 507 to the filter dust collection chamber 504 inside the suction fan 503. The filter dust collection chamber 504 filters and collects the drawn-in debris and dust, facilitating subsequent cleaning and preventing the debris and dust from affecting the processing environment and operators. As cutting progresses, the drive motor 3 continuously drives the lead screw 6 to rotate, causing the cutting blade 9 to continuously move towards the aluminum profile and complete the cutting operation. After cutting, the drive cylinder 406 drives the upper positioning seat 407 to reset upwards. The positioning clamp 403, under the action of the rotating shaft 402, rotates in the opposite direction around the rotating seat 401, releasing the clamp on the aluminum profile so that the cut aluminum profile can be removed.Then, adjusting the electric cylinder 505 causes the dust suction hood 506 to reset, and the drive motor 3 drives the cutting frame 8 and the cutting blade 9 back to their initial positions, ready for the next processing.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
