Abstract

The application relates to the technical field of intelligent manufacturing equipment industry, in particular to a length-adjustable cutting device for aluminum profile machining, which comprises an intelligent manufacturing workbench, a gear disc rotationally and clippingly installed at the top end of one side of the intelligent manufacturing workbench, and a central shaft penetratingly and clippingly installed in the middle position of the inside of the gear disc. The aluminum profile cutting device for the intelligent manufacturing industry is composed of a plurality of abutting thin plates and an electric telescopic rod by the setting of an inner supporting assembly, so that when cutting the thin-walled tubular aluminum profile, the electric telescopic rod is elongated, the abutting thin plates are expanded outward, tightly adhere to the inner wall of the aluminum profile, and form uniform and stable internal support. Compared with the traditional two-point clamping positioning mode, the inner supporting assembly can uniformly disperse the cutting force generated when the saw blade is cutting, avoid the local stress of the profile being too large, and greatly reduce the deformation problems such as the ovality out-of-tolerance and pipe opening wrinkles of the thin-walled aluminum profile caused by uneven stress.

Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing equipment technology, specifically to an adjustable-length cutting device for aluminum profile processing. Background Technology

[0002] Against the backdrop of the booming development of the intelligent manufacturing equipment industry, tubular aluminum profiles, as key structural materials in high-end manufacturing fields such as aerospace, rail transportation, and new energy vehicles, are becoming the core driving force for industrial upgrading due to their processing precision, efficiency, and level of intelligence.

[0003] Circular saws are a common type of sawing equipment. They use a high-speed rotating circular saw blade as the cutting tool. During operation, the electric motor drives the saw blade to rotate at high speed through a transmission device, providing power for cutting. The tubular aluminum profile is fixed on the worktable and is fed to the rotating saw blade by the feeding mechanism at a set speed and direction. The saw blade rotates and descends to contact the aluminum profile. Under the action of strong cutting force, it gradually cuts into the aluminum profile and cuts it off.

[0004] However, existing circular saw cutting machines face severe challenges when processing thin-walled aluminum profiles. The cutting and fixing mechanisms of traditional circular saw machines mostly adopt a two-point clamping positioning method. This method is difficult to provide uniform and stable support for thin-walled tubular aluminum profiles during the high-speed rotation and vertical descent of the circular saw blade. Due to the thin walls and poor rigidity of the aluminum profiles, the profile section between the two-point clamping area and the cutting point is prone to internal deformation under the cutting force of the saw blade. This results in problems such as excessive ellipticity and wrinkles at the tube ends of the cut profiles, which not only affect the appearance quality of the products but also reduce the mechanical properties and assembly accuracy of the profiles. In addition, the existing fixing mechanisms lack the ability to adaptively adjust to thin-walled aluminum profiles of different specifications and cannot be flexibly adjusted according to the diameter of the profile tube. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable length cutting device for aluminum profile processing, in order to solve the problem mentioned in the background art that traditional circular saws are difficult to provide uniform and stable support for thin-walled tubular aluminum profiles during cutting. Due to the thin walls and poor rigidity of thin-walled aluminum profiles, the profile part between the two-point clamping area and the cutting point is prone to internal deformation under the cutting force of the saw blade, resulting in the cut profile having excessive ellipticity and tube end wrinkles. At the same time, it lacks the ability to adaptively adjust to thin-walled aluminum profiles of different specifications.

A plurality of auxiliary wheels are evenly spaced on the bottom wall of the intelligent manufacturing workbench. A limit frame is fixedly installed on the top edge of the intelligent manufacturing workbench near the central shaft.

The motor drive frame has a circular saw blade fixedly mounted on the motor output shaft inside. Two strong magnets are symmetrically fixedly mounted on both sides of the circular saw blade on the motor drive frame. An internal support assembly is provided on the outside of the central shaft. The internal support assembly includes several abutment plates and an electric telescopic rod. The several abutment plates are arranged at equal angles around the outside of the central shaft. The electric telescopic rod is fixedly mounted on the outside of the gear disk on the side away from the several abutment plates. A U-shaped positioning block is fixedly installed through one side of each abutment plate. An oil wiping assembly is provided inside each positioning block.

[0008] Furthermore, each of the contact plates has several connecting brackets rotatably mounted at equal intervals on the inner wall of the side closest to the central axis. The end of each connecting bracket away from the contact plate is rotatably mounted on the outside of the central axis. Each of the contact plates has several mounting slots embedded at equal intervals on the outside. Each mounting slot has a motor drive wheel installed inside it.

[0009] Furthermore, an electric slide is fixedly installed on one side of the intelligent manufacturing workbench, and a pressure switch seat is fixedly installed on the side of the slide seat on the electric slide near the central axis.

[0010] Furthermore, a mounting bracket is fixedly installed on the side of the intelligent manufacturing workbench near the top of the gear disk, and a drive motor is fixedly installed on the outside of one side of the mounting bracket. A drive gear is fixedly installed on the output end of the drive motor, and one side of the drive gear meshes with one side of the gear disk.

[0011] Furthermore, an extrusion chamber is embedded in the middle of the side of the central shaft near the electric telescopic rod, and a piston rod is slidably and sealed inside the side of the extrusion chamber near the electric telescopic rod. An abutment frame is fixedly installed on the outside of the intelligent manufacturing workbench near the piston rod, and one end of the piston rod is rotatably engaged inside the side of the abutment frame.

[0012] Furthermore, a one-way liquid inlet valve pipe is fixedly installed through the bottom of the internal extrusion chamber on the side of the central shaft near the gear disk, and a storage tank is fixedly installed on one side of the gear disk. The input end of the one-way liquid inlet valve pipe of the storage tank is fixedly installed through the bottom side of the storage tank.

[0013] Furthermore, the oil wiping assembly includes two mounting boxes and two wiping cotton blocks. The two mounting boxes are symmetrically arranged on the inner walls of both sides of the positioning block. The two wiping cotton blocks are embedded and adhered to the inside of one of the mounting box openings on the corresponding side. Several positioning rods are fixedly installed at equal intervals on the outer side of each mounting box near the inner wall of the positioning block. One end of each positioning rod is slidably installed on the outer side of the positioning block away from the mounting box. A limit block is fixedly installed on the through end of each positioning rod. A one-way drain valve pipe is fixedly installed through one side of each mounting box. The input end of the one-way drain valve pipe is fixedly installed through one side of the squeezing chamber.

[0014] Furthermore, each of the positioning rods is fitted with a return spring on the side near the limiting block. The two ends of the return spring are respectively installed on one side of the limiting block and the positioning block. Each positioning block has a through hole on the side near the middle of each mounting box. Each mounting box has an arc-shaped abutment block fixedly installed on the side near the through hole. An auxiliary frame is fixedly installed on the side of the positioning block near the protruding end of the arc-shaped abutment block.

[0015] Furthermore, a compression rod is slidably installed longitudinally through the interior of the auxiliary frame. A compression spring is fixedly connected between the bottom end of the compression rod and the bottom wall of the auxiliary frame. An arc-shaped contact block two is fixedly installed on the outside of the compression rod near the arc-shaped contact block one. A powerful magnet two is fixedly installed at the top end of the compression rod. The adjacent surfaces of the powerful magnet two and the powerful magnet one are set with the same pole.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This intelligent manufacturing aluminum profile cutting device comprises several contact plates and an electric telescopic rod as its internal support assembly. Driven by the extension and retraction of the electric telescopic rod, the contact plates expand or contract at equal angles along the central axis. When cutting thin-walled tubular aluminum profiles, the electric telescopic rod extends, causing the contact plates to expand outwards and tightly adhere to the inner wall of the aluminum profile, forming a uniform and stable internal support. Compared to the traditional two-point clamping positioning method, this internal support assembly can evenly distribute the cutting force generated by the saw blade during cutting, preventing excessive local stress on the profile. This greatly reduces deformation problems such as excessive ellipticity and tube end wrinkling caused by uneven stress on thin-walled aluminum profiles. At the same time, the adjustable setting of the internal support component enables adaptive adjustment for thin-walled aluminum profiles of different specifications. In addition, the U-shaped positioning block opening on the contact plate ensures that the circular saw blade will not damage the contact plate body when cutting. Furthermore, the opening of the positioning block ensures that the inner wall of both the cut end and the raw material end of the thin-walled tube can be supported by several contact plates when the circular saw blade cuts, thus ensuring the overall cutting effect.

[0018] 2. This device utilizes an automatic lubrication system formed by the combination of an oil wiping component, an extrusion chamber, and a powerful magnet structure. This system ensures that the wiping cotton block adheres precisely to the cutting surfaces of the saw blade, guaranteeing sufficient lubrication for critical cutting areas. This effectively reduces the coefficient of friction between the saw blade and the aluminum profile, decreasing cutting resistance and resulting in smoother cutting, reduced surface roughness, and improved cutting precision. It significantly enhances lubrication efficiency and quality. Furthermore, it automatically supplies lubricant to the wiping cotton block inside the mounting box each time an aluminum profile is cut, resulting in better overall operation and greater convenience.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 8An adjustable-length cutting device for aluminum profile processing includes an intelligent manufacturing workbench 1, a gear disk 2 rotatably engaged and installed on the outer side of the top of one side of the intelligent manufacturing workbench 1, and a central shaft 3 slidably engaged and installed inside the gear disk 2 at its middle position. A plurality of auxiliary wheels 40 are evenly spaced on the bottom wall of the intelligent manufacturing workbench 1. A limit frame 23 is fixedly installed on the top side of the intelligent manufacturing workbench 1 near the central shaft 3. An electric telescopic rod 24 is longitudinally fixedly installed on the top of the limit frame 23, and a motor drive frame is fixedly installed at the bottom output end of the electric telescopic rod 24. 25. A circular saw blade 26 is fixedly installed on the motor output shaft inside the motor drive frame 25. Two strong magnets 27 are symmetrically fixedly installed on the outside of the motor drive frame 25 on both sides of the circular saw blade 26. An internal support assembly is provided on the outside of the central shaft 3. The internal support assembly includes several abutment plates 6 and an electric telescopic rod 9. The several abutment plates 6 are arranged at equal angles around the outside of the central shaft 3. The electric telescopic rod 9 is fixedly installed on the outside of the gear disk 2 on the side away from the several abutment plates 6. A U-shaped positioning block 17 is fixedly installed through one side of each abutment plate 6.

[0033] A fixing bracket 8 is fixedly installed on the outside of the central shaft 3 near the output end of the electric telescopic rod 9. The output end of the electric telescopic rod 9 is fixedly installed on one side of the fixing bracket 8. A limiting groove 4 is provided inside the gear disk 2 near each contact plate 6. A limiting slider 5 is slidably engaged inside the limiting groove 4. One side of the limiting slider 5 is fixedly installed on one end of the corresponding contact plate 6.

[0034] On the inner wall of each contact plate 6 near the central shaft 3, several connecting brackets 7 are rotatably installed at equal intervals. The end of each connecting bracket 7 away from the contact plate 6 is rotatably installed on the outer side of the central shaft 3. Several mounting slots 10 are embedded at equal intervals on the outer side of each contact plate 6. A motor drive wheel 11 is installed inside each mounting slot 10.

[0035] An electric slide table 12 is fixedly installed on one side of the intelligent manufacturing workbench 1. A pressure switch seat 13 is fixedly installed on the side of the slide table 12 near the central shaft 3.

[0036] A mounting bracket 14 is fixedly installed on the top side of the intelligent manufacturing workbench 1 near the gear disk 2. A drive motor 15 is fixedly installed on the outside of one side of the mounting bracket 14. A drive gear 16 is fixedly installed on the output end of the drive motor 15. One side of the drive gear 16 is meshed with one side of the gear disk 2.

[0037] In this embodiment, when using the aluminum profile cutting device for intelligent manufacturing, firstly, one end of the thin-walled aluminum profile to be cut is inserted into the end of the central shaft 3 away from the gear disk 2 using the existing feeding assembly. Then, the motor drive wheel 11, which abuts against the outside of the thin plate 6, is activated by control, causing the motor drive wheel 11 to come into contact with the inner wall of the profile and generate friction. At the same time, the auxiliary wheel 40 on the bottom wall of the intelligent manufacturing workbench 1 is set up to drive the thin-walled aluminum profile to move towards one side of the gear disk 2. During manufacturing, a spring can be installed between the bottom of the motor drive wheel 11 and the bottom wall of the mounting groove 10, so that when the thin plate 6 expands, the motor drive wheel 11 can compress and retract, and when the thin plate 6 contracts, the motor drive wheel 11 can spring back to reset contact, thus conveying the profile. When the thin-walled aluminum profile moves to a certain position, one end of the thin-walled aluminum profile contacts one side of the pressure switch seat 13, thereby causing the pressure switch seat 13 to control the motor drive wheel 11 to stop conveying, thus limiting the cutting length of the thin-walled aluminum profile. In later use, the existing electric slide table 12 can be controlled to move the pressure switch seat 13 on the slide block to other distances, thereby limiting different cutting lengths and ensuring the overall cutting convenience and accuracy. When the thin-walled aluminum profile is stopped, the electric telescopic rod 9 on one side is extended. The extension of the electric telescopic rod 9 drives the fixed frame 8 and the central shaft 3 to extend synchronously. Through the rotational connection of multiple connecting frames 7 to the contact plate 6, the central shaft 3 will drive several contact plates 6 on the side to expand synchronously when it extends. This allows the expanded contact plates 6 to fit tightly against the inner wall of the aluminum profile, forming a uniform and stable internal support. Compared with the traditional two-point clamping positioning method, this internal support component can evenly distribute the cutting force generated by the saw blade during cutting, avoiding excessive local stress on the profile. At the same time, the adjustable setting of the internal support component allows for adaptive adjustment for thin-walled aluminum profiles of different specifications, greatly reducing deformation problems such as ellipticity deviation and pipe end wrinkling caused by uneven stress on the thin-walled aluminum profile.

[0038] It should also be noted that after the thin-walled aluminum profile is positioned, the electric telescopic rod 24 drives the motor drive frame 25 and the rotating circular saw blade 26 to descend, causing the circular saw blade 26 to rotate and descend to cut the top of the thin-walled aluminum profile. At this time, the opening of the positioning block 17 ensures that the inner walls of both the cut end and the raw material end of the thin-walled profile are supported by several abutting thin plates 6 during the downward cutting of the circular saw blade 26, ensuring the overall cutting effect and preventing damage to the abutting thin plates 6. After the rotating circular saw blade 26 has finished cutting the top of the thin-walled aluminum profile, the drive motor 15 on one side is started. The rotation of the output shaft of the drive motor 15 drives the drive gear 16 on one side to rotate synchronously. The rotation of blade 16 causes the meshing gear disk 2 on one side to rotate, which in turn causes the limiting thin-walled aluminum profile to rotate synchronously. This allows the slowly rotating thin-walled aluminum profile to come into contact with the rotating circular saw blade 26 at the top, thus completing the overall cutting of the thin-walled aluminum profile. Through this slow-rotation cutting method, when cutting the thin-walled aluminum profile, the contact area between the circular saw blade 26 and the pipe is small, and the cutting force is dispersed. Combined with the uniform rotation of the pipe, the force exerted by the circular saw blade 26 on the pipe is evenly distributed in the circumferential direction, greatly reducing local stress concentration. This avoids the huge cutting force acting vertically on the pipe when the large saw blade directly descends to cut, which can easily cause the pipe to deform under single-point stress, such as dents or ellipticization, thus ensuring the overall cutting effect.

[0039] It should also be noted that after the overall cutting is completed, the electric telescopic rod 24 is controlled to drive the motor drive frame 25 and the stopped circular saw blade 26 to lift. Then, the electric telescopic rod 9 is controlled to drive the fixed frame 8 and the central shaft 3 to reset, so that the contact plate 6 is no longer tightly attached to the inner wall of the pipe. Subsequently, the motor drive wheel 11 is controlled to start rotating in the opposite direction again, so as to transport and discharge the cut pipe.

[0040] Example 2: Please refer to Figure 3 - Figure 4 as well as Figure 9 - Figure 11 This embodiment further illustrates that, in accordance with Example 1, each positioning block 17 is equipped with an oil wiping component.

[0041] An extrusion chamber 18 is embedded in the middle of the inner side of the central shaft 3 near the electric telescopic rod 9. A piston rod 19 is slidably and sealed inside the extrusion chamber 18 near the electric telescopic rod 9. An abutment frame 20 is fixedly installed on the outer side of the intelligent manufacturing workbench 1 near the piston rod 19. One end of the piston rod 19 is rotatably engaged inside the abutment frame 20.

[0042] A one-way inlet valve pipe 22 is fixedly installed through the bottom of the extrusion chamber 18 on the side of the central shaft 3 near the gear disk 2. A storage tank 21 is fixedly installed on one side of the gear disk 2. The input end of the one-way inlet valve pipe 22 of the storage tank 21 is fixedly installed through the bottom side of the storage tank 21.

[0043] The oil wiping assembly includes two mounting boxes 28 and two wiping cotton blocks 29. The two mounting boxes 28 are symmetrically arranged on the inner walls of both sides of the positioning block 17. The two wiping cotton blocks 29 are embedded and adhered to the opening of one of the mounting boxes 28 on the corresponding side. Several positioning rods 30 are fixedly installed at equal intervals on the outer side of the side of each mounting box 28 near the inner wall of the positioning block 17. One end of each positioning rod 30 is slidably installed on the outer side of the positioning block 17 away from the mounting box 28. A limit block 31 is fixedly installed on the through end of each positioning rod 30. A one-way drain valve pipe 39 is fixedly installed through one side of the mounting box 28. The input end of the one-way drain valve pipe 39 is fixedly installed through one side of the squeezing chamber 18.

[0044] Each positioning rod 30 is fitted with a return spring 32 on the side near the limiting block 31. The two ends of the return spring 32 are respectively installed on the side of the limiting block 31 and the positioning block 17. The side of the positioning block 17 near the middle position of each mounting box 28 is provided with a through hole 33. Each mounting box 28 is fixedly installed with an arc-shaped abutment block 34 on the side near the through hole 33. An auxiliary frame 35 is fixedly installed on the side of the positioning block 17 near the protruding end of the arc-shaped abutment block 34.

[0045] A compression rod 36 is slidably mounted longitudinally through the interior of the auxiliary frame 35. A compression spring is fixedly connected between the bottom end of the compression rod 36 and the bottom wall of the auxiliary frame 35. An arc-shaped abutment block 27 is fixedly mounted on the outside of the compression rod 36 near the arc-shaped abutment block 34. A strong magnet 28 is fixedly mounted on the top end of the compression rod 36. The adjacent surfaces of the strong magnet 28 and the strong magnet 27 are set with the same pole.

[0046] In this embodiment, when the extension of the electric telescopic rod 9 causes the side fixing frame 8 and the central shaft 3 to extend synchronously, the piston rod 19 is positioned by the contact frame 20, thereby causing the piston rod 19 to squeeze the lubricating oil that has been pre-drawn into the squeezing chamber 18. The squeezed oil is then discharged through the one-way drain valve pipe 39 into the wiping cotton block 29 inside the mounting box 28. This ensures that the entire device can replenish the oil inside the wiping cotton block 29 each time a single pipe is cut. Simultaneously, when the retraction of the electric telescopic rod 9 causes the side fixing frame 8 and the central shaft 3 to retract synchronously, the piston rod 19 moves back within the squeezing chamber 18. At this time, the oil is released through the one-way inlet valve pipe 22 and the storage tank 21. The hydraulic system draws a certain amount of hydraulic oil into the extrusion chamber 18 to complete the fluid replenishment operation. The overall performance is good and the system is convenient. When encountering pipes with larger diameters, the electric telescopic rod 9 moves the central shaft 3 a longer distance, ensuring that the contact plate 6 can contact and adhere to the inner wall of the pipe. Conversely, when encountering pipes with smaller diameters, the electric telescopic rod 9 moves the central shaft 3 a shorter distance, allowing the piston rod 19 to adapt its extrusion movement distance within the extrusion chamber 18 inside the central shaft 3. This allows the supplied hydraulic oil to be adjusted when cutting pipes of different diameters, avoiding excessive waste or insufficient damage, resulting in a better overall performance.

[0047] It should also be noted that when the electric telescopic rod 24, motor drive frame 25, and circular saw blade 26 descend to cut the pipe, after the circular saw blade 26 has finished cutting the top of the pipe, the bottom of the circular saw blade 26 is inserted into one of the positioning blocks 17. At this time, the strong magnets 27 on both sides of the motor drive frame 25 contact the corresponding strong magnets 38 on both sides of the bottom. Through the same pole arrangement of the adjacent surfaces of the strong magnets 38 and the strong magnets 27, the strong magnets 27 will resist and repel the strong magnets 38, thereby causing the strong magnets 38 to descend. When the strong magnets 38 descend, they will drive the compression rod 36 to descend synchronously. When the compression rod 36 descends, it will drive the arc-shaped contact block 37 on one side of the bottom to descend, thereby causing the arc-shaped contact block 37 to resist and compress the arc-shaped contact block 34 on one side. This causes the arc-shaped contact block 34 to be forced to move the mounting box 28 and the wiping cotton. Block 29 moves towards the side of the circular saw blade 26, thereby bringing the wiping cotton block 29 into contact with the circular saw blade 26. This lubricates and maintains the circular saw blade 26, ensuring precise contact and adequate lubrication of key cutting areas. This effectively reduces the coefficient of friction between the saw blade and the aluminum profile, decreases cutting resistance, makes cutting smoother, reduces surface roughness, and improves cutting accuracy, significantly enhancing lubrication efficiency and quality. When the second strong magnet 38 moves away from the first strong magnet 27, the return spring 32 and the compression spring at the bottom of the compression rod 36 cause the mounting box 28 and the wiping cotton block 29 to move back and detach from the side wall of the circular saw blade 26. This allows the circular saw blade 26 to exit smoothly, preventing direct contact with the circular saw blade 26 and avoiding tearing damage to the wiping cotton block 29. This reduces the replacement frequency of the wiping cotton block 29 and extends its service life.
