Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment industry, and specifically to a length-adjustable cutting device for processing aluminum profiles. Background Art

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

[0003] Circular saw machine is a more common sawing equipment, which uses a high-speed rotating circular saw blade as a cutting tool. When working, the motor drives the saw blade to rotate at high speed through the transmission device to provide power for cutting. The tubular aluminum profile is fixed on the workbench, and the profile is conveyed to the rotating saw blade according to the set speed and direction through the feeding mechanism. 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 and 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 in the cutting process. Due to the thin wall and poor rigidity of thin-walled aluminum profiles, under the action of the saw blade cutting force, the profile part between the two-point clamping area and the cutting point is very prone to internal deformation, resulting in excessive ovality and wrinkles on the pipe mouth of the cut profile. This not only affects the appearance quality of the product, but also reduces the mechanical properties and assembly accuracy of the profile. In addition, the existing fixing mechanism lacks the ability to adaptively adjust to thin-walled aluminum profiles of different specifications, and cannot be flexibly adjusted according to the profile diameter. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This intelligent manufacturing industry aluminum profile cutting device is composed of several pieces of resistance thin plates and an electric telescopic rod. The electric telescopic rod is driven by the extension and contraction of the resistance thin plates along the outside of the central axis. When cutting thin-walled tubular aluminum profiles, the electric telescopic rod is extended, and the resistance thin plates expand outwards, closely fitting the inner wall of the aluminum profile to form a uniform and stable internal support. Compared with the traditional two-point clamping positioning method, the internal support component can evenly disperse the cutting force generated by the saw blade during cutting, avoiding excessive local force on the profile, which is extremely The deformation problems of thin-walled aluminum profiles such as excessive ovality and wrinkles at the pipe mouth caused by uneven force are greatly reduced. At the same time, the adjustable setting of the inner support component enables adaptive adjustment of thin-walled aluminum profiles of different specifications. At the same time, the U-shaped positioning block opening on the resisting thin plate is set, so that the circular saw blade will not damage the body of the resisting thin plate when it descends for cutting. At the same time, the opening setting of the positioning block ensures that when the circular saw blade descends for cutting, the cut end of the thin-walled pipe and the inner wall of the raw material end can be supported by several resisting thin plates to ensure the overall cutting effect.

[0018] 2. This device uses an automatic lubrication system formed by the oil wiping component, the extrusion chamber and the strong magnet structure, so that the wiping cotton block can fit accurately to ensure that the key cutting parts of the saw blade are fully lubricated, effectively reducing the friction coefficient between the saw blade and the aluminum profile, reducing cutting resistance, making the saw blade cut more smoothly, reducing the roughness of the cutting surface, and improving cutting accuracy, which significantly improves the lubrication efficiency and quality. At the same time, it can automatically supply liquid to the wiping cotton block inside the installation box each time the aluminum profile is cut, and the overall operation effect is better and more convenient.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figure 1 - Figure 8A length-adjustable cutting device for aluminum profile processing includes an intelligent manufacturing workbench 1, a gear plate 2 rotatably mounted on the outside of the top of one side of the intelligent manufacturing workbench 1, and a central shaft 3 that penetrates and slides and is mounted in the middle position of the gear plate 2. 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 mounted on one side of the top of the intelligent manufacturing workbench 1 near the central shaft 3. An electric telescopic rod 24 is fixedly mounted on the top of the limit frame 23. A motor drive frame is fixedly mounted on the output end of the bottom 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 a plurality of conflicting thin plates 6 and an electric telescopic rod 9. The plurality of conflicting thin 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 plate 2 away from the plurality of conflicting thin plates 6. A U-shaped positioning block 17 is fixedly installed inside one side of each conflicting thin plate 6.

[0033] A fixing frame 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 fixed to one side of the fixing frame 8. A limiting slide groove 4 is provided inside the gear plate 2 near one side of each contact sheet 6. A limiting slider 5 is slidably engaged with the inside of the limiting slide groove 4. One side of the limiting slider 5 is fixed to one end of the contact sheet 6 on the corresponding side.

[0034] A number of connecting frames 7 are rotatably mounted at equal intervals on the inner wall of one side of each resisting thin plate 6 close to the central axis 3. An end of each connecting frame 7 away from the resisting thin plate 6 is rotatably mounted on the outside of one side of the central axis 3. A number of mounting grooves 10 are embedded at equal intervals on the outside of each resisting thin plate 6, and a motor drive wheel 11 is installed inside each mounting groove 10.

[0035] An electric slide 12 is fixedly mounted on one side of the intelligent manufacturing workbench 1 , and a pressure switch seat 13 is fixedly mounted on the outside of the slide seat of the electric slide 12 close to the central axis 3 .

[0036] A mounting bracket 14 is fixedly installed on one side of the top of the intelligent manufacturing workbench 1 near the gear plate 2, a driving motor 15 is fixedly installed on the outside of one side of the mounting bracket 14, and a driving gear 16 is fixedly installed on the output end of the driving motor 15, and one side of the driving gear 16 is meshed and connected with one side of the gear plate 2.

[0037] In this embodiment, when the aluminum profile cutting device for the intelligent manufacturing industry is in use, first, through the existing feeding assembly, one end of the thin-walled aluminum pipe fitting to be cut is inserted into the end of the central axis 3 away from the gear disk 2, and then the motor drive wheel 11 on the outside of the contact thin plate 6 is controlled to start, so that the motor drive wheel 11 fits the inner wall of the pipe fitting to produce friction, and at the same time cooperates with the auxiliary wheel 40 on the bottom wall of the intelligent manufacturing workbench 1, thereby driving the thin-walled aluminum pipe fitting to be transported and moved to one side of the gear disk 2. At the same time, a spring can be installed between the bottom of the motor drive wheel 11 and the bottom wall of the mounting groove 10 during production, so that when the contact thin plate 6 expands later, the motor drive wheel 11 can be compressed and retracted, and when the contact thin plate 6 contracts, the motor drive wheel 11 can rebound and reset the contact to transport the pipe fitting. When the thin-walled aluminum pipe fitting moves to a certain position, one end of the thin-walled aluminum pipe fitting contacts one side of the pressure switch seat 13, so that the pressure switch seat 13 controls the motor drive wheel 11 to stop transporting, thereby limiting the cutting length of the thin-walled aluminum pipe fitting. When in use later, the existing electric slide 12 can be controlled to drive the pressure switch seat 13 on the slide to move other distances, so as to limit different cutting lengths and ensure the overall cutting convenience and accuracy. When the thin-walled aluminum pipe is stopped, the electric telescopic rod 9 on one side is controlled to extend. The extension of the electric telescopic rod 9 drives the fixed frame 8 on one side and the central axis 3 to extend synchronously. The multiple connecting frames 7 are used to connect the rotation of the resistance thin plate 6, so that when the central axis 3 is extended, it will drive the several resistance thin plates 6 on the side to expand synchronously, so that the expanded resistance thin plates 6 are tightly fitted to the inner wall of the aluminum profile to form a uniform and stable internal support. Compared with the traditional two-point clamping positioning method, the internal support component can evenly disperse the cutting force generated by the saw blade during cutting, avoiding excessive local force on the profile. At the same time, through the adjustable setting of the internal support component, it can adaptively adjust thin-walled aluminum profiles of different specifications, greatly reducing the deformation problems of thin-walled aluminum profiles such as excessive ovality and wrinkles at the pipe mouth caused by uneven force.

[0038] It should also be noted that when the positioning of the thin-walled aluminum pipe is completed, the electric telescopic rod 24 is controlled to drive the motor drive frame 25 and the rotating circular saw blade 26 to descend, so that the circular saw blade 26 rotates and descends to cut the top of the thin-walled aluminum pipe. At this time, the opening of the positioning block 17 is set so that when the circular saw blade 26 descends for cutting, the cut end of the thin-walled pipe and the inner wall of the raw material end can be fitted and supported by several pieces of contact thin plates 6 to ensure the overall cutting effect. At the same time, it can also ensure that the main body of the contact thin plate 6 will not be damaged when the circular saw blade 26 descends for cutting. When the rotating circular saw blade 26 descends and completes the cutting of the top of the thin-walled aluminum pipe, one side drive motor 15 is started at this time, and the output shaft of the drive motor 15 is rotated, thereby driving the one side drive gear 16 to rotate synchronously, and the drive gear 16 rotates, thereby driving the meshing gear plate 2 on one side to start rotating, so that the rotation of the gear plate 2 drives the limited thin-walled aluminum pipe fitting to rotate synchronously, so that the slowly rotating thin-walled aluminum pipe fitting contacts the circular saw blade 26 rotating at the top, thereby completing the overall cutting of the thin-walled aluminum pipe fitting. Through this slow rotating cutting method, when cutting the thin-walled aluminum pipe fitting, the circular saw blade 26 has a small contact area with the pipe when cutting around, and the cutting force is dispersed. In conjunction with the uniform rotation of the pipe, the force of the circular saw blade 26 on the pipe is evenly distributed in the circumferential direction, which greatly reduces local stress concentration and avoids the huge cutting force acting vertically on the pipe when the large saw blade directly descends for cutting, which easily causes the pipe to be deformed such as concave and elliptical under single-point force, thereby ensuring the overall cutting effect.

[0039] It should also be noted that when 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 rise, and then the electric telescopic rod 1 9 is controlled to drive the fixed frame 8 and the central axis 3 to reset, so that the contact thin plate 6 is recovered and no longer tightly fits the inner wall of the pipe. Subsequently, the motor drive wheel 11 is controlled to start reverse rotation again, so that the cut pipe is transported and discharged.

[0040] Example 2: Please refer to Figure 3 - Figure 4 as well as Figure 9 - Figure 11 This embodiment further illustrates the first embodiment, in which an oil wiping component is provided inside the positioning block 17 .

[0041] An extrusion chamber 18 is embedded in the middle position of the inner side of the central axis 3 close to the electric telescopic rod 9, and a piston rod 19 is installed in a sliding seal inside the extrusion chamber 18 close to the electric telescopic rod 9. A resistance frame 20 is fixedly installed on the outside of the intelligent manufacturing workbench 1 close to the piston rod 19, and one end of the piston rod 19 is rotatably engaged and installed inside one side of the resistance frame 20.

[0042] A one-way liquid inlet valve tube 22 is fixedly installed through the bottom of the internal extrusion chamber 18 on the side of the central shaft 3 close to the gear plate 2, and a storage tank 21 is fixedly installed on one side of the gear plate 2. The input end of the one-way liquid inlet valve tube 22 of the storage tank 21 is fixedly installed inside 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 on both sides of the positioning block 17. The two wiping cotton blocks 29 are embedded and adhered to the opening of a mounting box 28 on the corresponding side. A number of positioning rods 30 are fixedly installed at equal intervals on the outside of each mounting box 28 close to the inner wall of the positioning block 17. One end of the number of positioning rods 30 is slidably installed on the outside of the side of the positioning block 17 away from the mounting box 28. A limiting block 31 is fixedly installed on the through end of each positioning rod 30. A one-way drain valve pipe 39 is fixedly installed on the inside of one side of the mounting box 28. The input end of the one-way drain valve pipe 39 is fixedly installed on the inside of one side of the extrusion chamber 18.

[0044] A return spring 32 is sleeved on the outside of each positioning rod 30 near the limit block 31, and the two ends of the return spring 32 are respectively installed on one side of the limit block 31 and the positioning block 17. A through hole 33 is penetrated inside the side of the positioning block 17 near the middle position of each installation box 28, and an arc-shaped interference block 34 is fixedly installed on the side of each installation box 28 near the through hole 33. An auxiliary frame 35 is fixedly installed on the outside of the positioning block 17 near the protruding end of the arc-shaped interference block 34.

[0045] A compression rod 36 is slidably installed longitudinally through the interior of the auxiliary frame 35, and 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 resistance block 2 37 is fixedly installed on the outside of the compression rod 36 near the arc-shaped resistance block 1 34, and a strong magnet 2 38 is fixedly installed on the top of the compression rod 36. The adjacent surfaces of the strong magnet 2 38 and the strong magnet 1 27 are set with the same poles.

[0046] In this embodiment, when the extension of the electric telescopic rod 9 drives the one side fixing frame 8 and the central axis 3 to extend synchronously, the piston rod 19 is positioned by the resistance frame 20, so that the piston rod 19 squeezes the lubricating oil previously sucked into the extrusion chamber 18, so that the squeezed oil is discharged into the wiping cotton block 29 inside the installation box 28 through the one-way discharge valve pipe 39, so that the entire device can replenish the oil inside the wiping cotton block 29 once each time a single pipe is cut. At the same time, when the recovery of the electric telescopic rod 9 drives the one side fixing frame 8 and the central axis 3 to recover synchronously, the piston rod 19 is withdrawn and moved inside the extrusion chamber 18. At this time, the one-way liquid inlet valve pipe 22 and the storage tank 21 are used. The conduction is turned on, thereby sucking a certain amount of hydraulic oil into the interior of the extrusion chamber 18 to complete the fluid replenishment operation. The overall use effect is good and the convenience is high. When encountering a pipe with a larger diameter, the electric telescopic rod 9 drives the central axis 3 to move a longer distance, thereby ensuring that the contact thin plate 6 can contact the inner wall of the fitting. On the contrary, when encountering a pipe with a smaller diameter, the electric telescopic rod 9 drives the central axis 3 to move a shorter distance, thereby making it possible for the piston rod 19 to move in the extrusion chamber 18 inside the central axis 3 to adapt to the change. Therefore, when cutting pipes of different diameters, the supplied oil can also adapt to the change, avoiding excessive waste or too little damage, and the overall use effect is better.

[0047] It should also be noted that when the electric telescopic rod 24, the motor drive frame 25 and the circular saw blade 26 descend to cut the pipe fitting, when the circular saw blade 26 completes cutting the top of the pipe fitting, the bottom of the circular saw blade 26 is inserted into one of the positioning blocks 17. At this time, the strong magnet 1 27 on both sides of the motor drive frame 25 contacts the strong magnet 2 38 corresponding to the two sides of the bottom end. Through the setting of the same poles of the strong magnet 2 38 and the adjacent surfaces of the strong magnet 1 27, the strong magnet 1 27 will resist and repel the strong magnet 2 38, thereby causing the strong magnet 2 38 to descend. When the strong magnet 2 38 descends, it will drive the compression rod 36 to descend synchronously. When the compression rod 36 descends, it will drive the arc-shaped resistance block 2 37 on one side of the bottom end to descend, thereby causing the arc-shaped resistance block 2 37 to resist and squeeze the arc-shaped resistance block 1 34 on one side, so that the arc-shaped resistance block 1 34 is forced to drive the installation box 28 and the wiping cotton The block 29 moves toward the side of the circular saw blade 26, so that the wiping cotton block 29 is in contact with the circular saw blade 26, thereby lubricating and maintaining the circular saw blade 26, so that the wiping cotton block 29 can fit accurately to ensure that the key cutting parts of the saw blade are fully lubricated, effectively reducing the friction coefficient between the saw blade and the aluminum profile, reducing cutting resistance, making the saw blade cut more smoothly, reducing the roughness of the cutting surface, improving cutting accuracy, and significantly improving lubrication efficiency and quality. When the strong magnet 2 38 is away from the strong magnet 1 27, the reset spring 32 and the compression spring at the bottom of the compression rod 36 rebound, so that the mounting box 28 and the wiping cotton block 29 move back and away from the side wall of the circular saw blade 26, so that the circular saw blade 26 can be smoothly withdrawn, and the direct contact of the circular saw blade 26 to avoid the wiping cotton block 29 from being torn and damaged, reduces the replacement frequency of the wiping cotton block 29, and extends its service life.
