Description

Technical Field

[0001] The present application relates to the technical field of metal cutting, and in particular to an aluminum profile cutting device. Background Art

[0002] Aluminum profiles are widely used in the fields of construction, automobile manufacturing, aerospace, and home decoration due to their light weight, corrosion resistance, and easy processing. In the aluminum profile processing, cutting is one of the key processes, and its accuracy directly affects the subsequent assembly and product performance. With the development of industrial automation, higher requirements are placed on the efficiency, accuracy, and stability of aluminum profile cutting equipment, especially for the cutting of special-shaped or thin-walled profiles, which requires ensuring that the cut is smooth and the size is accurate.

[0003] In the prior art, a Chinese patent with publication number CN105269068A discloses an aluminum profile cutting device, including a cutting machine, a belt conveyor, a glass cover, a collection box and other components. Its working process is as follows: the cutting machine conveys aluminum profiles through a belt conveyor, and grooves are set on the surface of the conveyor belt to fix the workpiece. After cutting, the workpiece is introduced into the collection box by the transmission plate, and the debris is removed by a cleaning brush. The equipment reduces noise through a glass cover, improves efficiency through automated transmission, and is designed with a double collection box to simplify the cleaning process.

[0004] However, since aluminum profiles are limited only by the grooves on the surface of the conveyor belt when cutting, when cutting at high speed or processing special profiles, the aluminum profiles are prone to swing due to uneven force or inertia, resulting in deviation of the cutting path, and then causing dimensional errors or cutting burrs. Circular saw disc-type cutting machines require a deeper cutting depth, which will increase the force on the aluminum profiles, further exacerbating the material shaking problem and seriously affecting the cutting accuracy. Summary of the invention

[0005] In order to reduce the impact on the cutting accuracy of aluminum profiles, the present application provides an aluminum profile cutting device.

[0006] The present application provides an aluminum profile cutting device, which adopts the following technical solution: An aluminum profile cutting device, comprising: The workbench forms a flat work surface and is provided with a clearance groove; A support frame, arranged on the workbench; The cutting mechanism comprises a cutting frame sliding on the support frame in a vertical direction, a cutting saw rotating on the cutting frame, a power member arranged on the cutting frame for driving the cutting saw to rotate, and a sliding assembly arranged on the support frame for driving the cutting frame to move, wherein the cutting saw can rotate in the clearance groove through the sliding assembly; The positioning mechanism comprises a positioning block and a force-applying component. The positioning block slides on the workbench in a vertical direction through the force-applying component, and the positioning block presses and positions the aluminum profile on the workbench.

[0007] By adopting the above technical solution, when cutting aluminum profiles, first place the aluminum profile on the workbench, press the positioning block downward to fix the profile through the force-applying component, and then use the sliding component to drive the cutting saw close to the profile. In the process of approaching, the power part drives the cutting saw to rotate, and the cutting saw contacts the profile and cuts the profile. During the cutting process, the cutting saw enters the make way groove to reduce the damage of the cutting saw to the workbench.

[0008] By pressing vertically with the positioning block, the longitudinal jump of the profile is directly suppressed, and the cutting path is limited by the clearance groove, which significantly improves the positioning accuracy and avoids cutting deviation. The setting of the clearance groove facilitates the cutting saw to cut deeply into the profile, optimizes the cutting edge, and can reduce the interference of the workbench on the cutting saw. Combined with the setting of the positioning block, the aluminum profile is easy to be evenly stressed, the probability of swinging is reduced, and the deviation of the cutting path is reduced, thereby reducing dimensional errors, reducing cutting burrs, and reducing the impact on the cutting accuracy of the aluminum profile.

[0009] Optionally, at least two groups of positioning blocks are provided, and the two groups of positioning blocks are respectively located on both sides of the clearance groove.

[0010] By adopting the above technical solution, two sets of positioning blocks are pressed down synchronously from both sides of the profile to clamp the area to be cut; the single conveyor belt groove only provides bottom limit and has no lateral constraints; the double-sided positioning blocks form a lateral clamping force to effectively prevent the profile from lateral sliding or twisting, further reducing the risk of cutting deviation.

[0011] Optionally, two groups of the cutting mechanisms are symmetrically arranged on the workbench, and two groups of the positioning mechanisms are correspondingly arranged.

[0012] By adopting the above technical solution, two sets of cutting mechanisms cut both ends of the profile at the same time, and are fixed synchronously with the double positioning mechanism; the efficiency of a single cutting machine is limited and cannot meet the needs of batch processing; the double-station design realizes parallel cutting and improves processing efficiency, and the symmetrical layout ensures balanced cutting force and reduces equipment vibration.

[0013] Optionally, the cutting mechanism includes two cutting saws, the cutting paths of the two cutting saws are set at an angle, and the two cutting saws are spaced apart in the vertical direction.

[0014] By adopting the above technical solution, the upper and lower cutting saws cut into the profile at different angles successively to complete compound cutting; a single cutting saw can only complete plane cutting, and multiple adjustments are required for complex profiles; multi-angle cutting can form special-shaped cuts (such as V-shaped grooves) in one time, reducing process switching, improving processing accuracy and efficiency, and can meet the one-time cutting of a single outer frame of the thermally broken aluminum window, improving efficiency and reducing cutting errors caused by movement or changing sides.

[0015] Optionally, a blowing mechanism is provided on the workbench, and the blowing mechanism includes a blowing head and an air source; the blowing head is arranged on the workbench, facing the give way groove, and is used to blow away the debris generated by cutting; the air source is used to supply air to the blowing head.

[0016] By adopting the above technical solution, the air blowing head sprays air during cutting to blow the debris away from the clearance groove, and actively blows air to immediately remove the debris, avoiding the accumulation of debris interfering with the cutting path, while reducing the downtime for cleaning. The set blowing mechanism can reduce the adhesion of debris between the aluminum profile and the workbench, reduce the upward warping of the aluminum profile, and reduce the scratches on the aluminum profile by the debris, thereby improving the cutting accuracy and product quality.

[0017] Optionally, two groups of the blowing mechanisms are provided and are respectively located on both sides of the giving way groove.

[0018] By adopting the above technical solution, the air blowing heads on both sides spray air at the same time, forming a cross airflow to cover the cutting area; the double-sided blowing covers a wider area, completely removing debris in and around the groove to ensure a clean cutting environment.

[0019] Optionally, the blowing head is located on the travel path of the aluminum profile; a sliding frame is provided on the blowing head, and the sliding frame slides on the workbench in a vertical direction; a lifting assembly is provided on the workbench, and the lifting assembly is connected to the sliding frame to drive the sliding frame to move up and down.

[0020] By adopting the above technical scheme, when the aluminum profile is placed or moved on the workbench, the set air blowing head can lift the aluminum profile so that the air blowing head can blow on the workbench, and the aluminum profile does not contact the workbench, so that the cleaning effect is improved, and the contact surface between the aluminum profile and the workbench can be cleaned, reducing the debris between the aluminum profile and the workbench, and facilitating the movement of the aluminum profile; when the positioning block presses the aluminum profile, the lifting assembly is used to drive the air blowing head downward, so that the aluminum profile contacts the workbench, and then the positioning block is used to press it, and then cutting is performed; through the above arrangement, the debris between the aluminum profile and the workbench is further reduced, the positioning and fixing effect of the aluminum profile is improved, and the cutting accuracy is improved.

[0021] Optionally, the blowing head is spherical and has a plurality of blowing holes; the blowing head is rotatably disposed on the sliding frame, and the aluminum profile can be tangent to the blowing head.

[0022] By adopting the above technical solution, the air blowing head moves and rotates with the profile, and the air jets cover the cutting surface at multiple angles; the cleaning efficiency in a fixed direction is low, and there are cleaning dead corners; the spherical head with multiple holes can realize all-round debris cleaning, and the self-rotation feature avoids airflow blind spots, improves cleaning efficiency, and makes the cutting surface of the aluminum profile and the contact surface with the workbench cleaner.

[0023] Optionally, the lifting assembly includes a lifting spring, which is connected to the sliding frame and pushes the sliding frame to approach the aluminum profile.

[0024] By adopting the above technical solution, the spring automatically presses the blowing head so that it always fits the surface of the profile; the elastic adaptive mechanism ensures that the blowing head is in close contact with the profile without manual intervention, thereby improving the level of automation; and it can provide support when the aluminum profile moves, and can roll and clean the aluminum profile during the support process.

[0025] Optionally, a steel brush is provided on the air blowing head, and an extension frame and a side blowing assembly are also provided on the workbench. The extension frame rotates on the workbench, and the side blowing assembly is arranged on the extension frame. The side blowing assembly faces the give way groove and is used to blow the cutting saw; the sliding frame abuts against one end of the extension frame, and when the sliding frame moves away from the aluminum profile, the extension frame is squeezed to rotate, so that the side blowing assembly on the extension frame swings in a direction away from the aluminum profile.

[0026] By adopting the above technical solution, when the positioning block presses the aluminum profile, the sliding frame moves in the direction away from the aluminum profile, and the sliding frame squeezes the extension frame to make the extension frame rotate. The extension frame drives the side blowing assembly to blow downward at an angle. When cutting, the side blowing assembly blows on the cutting saw to reduce the surface temperature of the cutting saw, extend the cutting time, and reduce the adhesion of surface debris; the side blowing assembly cooperates with the air blowing head to clean the aluminum profile, the workbench and the cutting saw, reduce the environmental impact, and maintain the cutting accuracy.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. The vertical pressing of the positioning block directly suppresses the longitudinal jump of the profile, and the use of the clearance groove to limit the cutting path significantly improves the positioning accuracy and avoids cutting deviation. The setting of the clearance groove facilitates the cutting saw to cut the profile in depth, optimizes the cutting edge, and can reduce the interference of the workbench on the cutting saw. In combination with the setting of the positioning block, the aluminum profile is easy to be evenly stressed, the probability of swinging is reduced, and the deviation of the cutting path is reduced, thereby reducing the dimensional error, reducing the cutting burrs, and reducing the impact on the cutting accuracy of the aluminum profile; 2.

When the positioning block presses the aluminum profile, the sliding frame moves in the direction away from the aluminum profile, and the sliding frame squeezes the extension frame to make the extension frame rotate.

The positioning plate 622 on the conveyor belt 621 abuts against both sides of the aluminum profiles to ensure that they are symmetrically arranged along the partition 810.

[0047] The lifting cylinder drives the lifting frame 631 to rise, and the lifting roller 632 contacts the bottom surface of the aluminum profile to lift it away from the conveyor belt 621. The separation roller and the adjustment roller 637 limit the longitudinal and lateral positions of the aluminum profile respectively. The double-rod cylinder drives the adjustment roller 637 to move to correct the centering state of the aluminum profile; the clamping cylinder of the push assembly 640 drives the second clamping block 647 to approach the first clamping block 646 to clamp the two sides of the aluminum profile; the motor drives the sliding seat 642 to move along the sliding track 641 through the gear rack (775) to push the aluminum profile to the cutting area of ​​the workbench 100.

[0048] The hydraulic cylinder of the force-applying assembly 420 drives the positioning block 410 to press down, applying vertical pressure from the top of the aluminum profile. At the same time, the positioning blocks 410 on both sides of the partition 810 form a double-sided clamping force to suppress the longitudinal jump and lateral sliding of the profile.

[0049] The servo motor drives the cutting frame 310 to move down along the vertical guide rail of the support frame 200 through the ball screw, and the driving member 330 drives the cutting saw 320 to rotate at high speed. The upper and lower cutting saws 320 successively cut into the aluminum profile at an angle of 45°, and the cutting path enters the clearance groove 110 and the cutting groove 120 to complete the one-time forming of the V-shaped groove or special-shaped cut.

[0050] Two sets of symmetrically arranged cutting mechanisms 300 cut the aluminum profiles on both sides of the partition 810 at the same time, achieving efficient parallel processing.

[0051] Before or after the aluminum profile is cut, the spring drives the air blowing head 510 to lift the aluminum profile, and the air source supplies air to the spherical air blowing head 510 through the air pipe 540, and multiple air blowing holes spray high-pressure air to remove the cutting debris in the clearance groove 110. The air blowing head 510 rises and falls with the sliding frame 520, and the lifting spring 532 pushes it to always fit the surface of the aluminum profile, and the steel brush synchronously scrapes the residual debris on the profile surface.

[0052] After the cutting is completed, the front half of the aluminum profile is lifted up by the lifting spring 532, reducing the contact with the workbench 100, and is moved away from the workbench 100 under the action of the discharge conveyor belt 621, and the air blowing head 510 blows and cleans the cutting seam and the workbench 100; when the pushing assembly 640 drives the aluminum profile to continue to move forward, the end of the aluminum profile is slightly lifted up by the lifting spring 532, and then crosses the give way groove 110 and abuts against the air blowing head 510, and as the air blowing head 510 rotates, the cutting seam is cleaned, and the side wall of the aluminum profile close to the workbench 100 is cleaned.

[0053] When the positioning block 410 presses down the aluminum profile, the sliding frame 520 moves down, and the transmission rod 570 squeezes the limit rod 580 of the extension frame 550, driving the high-pressure nozzle of the side blowing assembly 560 to spray air toward the cutting saw 320, cooling the tool and removing adhered debris, and continuously spraying air during the cutting process, thereby reducing the adhesion of debris on the cutting saw 320 and extending the service life of the cutting saw 320; the cut aluminum profile is transported away from the workbench 100 via the receiving conveyor belt 710, and the receiving roller 750 rolls to assist it in sliding to the receiving table 720.

[0054] The push cylinder 740 drives the push plate 730 to push the aluminum profiles to the designated stacking area to complete batch sorting.

[0055] The double-sided positioning blocks 410 and the partition 810 cooperate to suppress the swing, and the cutting size error is less than 0.1mm; the double-station and double-cutting saw 320 design increases the processing efficiency by 60%, which is suitable for complex profile processing; the air blowing head 510 and the side blowing component 560 are linked, the debris removal rate exceeds 98%, and the tool life is extended by 30%; loading, cutting, cleaning, and collecting are seamlessly connected, reducing manual intervention, and are suitable for industrial mass production.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
