Description

Technical Field

[0001] This application belongs to the field of cutting machine technology, and more specifically, relates to a fixed-length cutting device for aluminum profile processing. Background Technology

[0002] In the production and processing of aluminum profiles, length-fixed cutting is a crucial step, as its precision and stability directly affect the assembly quality and performance of subsequent products. Traditional length-fixing methods rely heavily on manual measurement and marking, which is not only inefficient but also prone to inconsistent cutting lengths due to human error, making it difficult to meet the demands of high-volume, high-precision production. Furthermore, the high-speed rotating cutting blade generates significant impact and vibration during cutting. If the aluminum profile is not securely fixed, it is highly susceptible to displacement, wobbling, or even bouncing. This can lead to uneven cut surfaces, burrs, or beveled cuts, affecting product quality and potentially causing safety accidents, threatening the personal safety of operators. Utility Model Content

[0003] Based on the above-mentioned technical problems, this application provides a fixed-length cutting device for aluminum profile processing to solve the technical problems in the prior art that manual measurement is not only inefficient, but also prone to inconsistent cutting lengths due to human operation errors, making it difficult to meet the needs of mass production and high-precision production, and that the aluminum profile is not firmly fixed during cutting, affecting product quality.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: a fixed-length cutting device for aluminum profile processing is provided, comprising an input section, a cutting section, and an output section sequentially connected along the moving direction of the aluminum profile. A fixed-length component for controlling the cutting length of the aluminum profile is slidably disposed on the cutting section. The cutting section includes a worktable and a cutting blade rotatably disposed above the worktable. The cutting direction of the cutting blade is perpendicular to the moving direction of the aluminum profile. On the cutting section, a first positioning component and a second positioning component for fixing the aluminum profile are respectively disposed on both sides of the axial direction of the cutting blade.

[0005] Furthermore, the cutting blade includes a bracket, a blade for cutting the aluminum profile rotatably mounted at one end of the bracket, and a first motor for driving the blade to rotate. The end of the bracket away from the blade is rotatably connected to the top surface of the workbench. A side plate is fixedly provided on one side of the workbench. A first telescopic cylinder is provided between the side plate and the bracket. The two ends of the first telescopic cylinder are rotatably connected to the side plate and the bracket, respectively.

[0006] Furthermore, the first positioning component includes baffles fixedly disposed at intervals on one side of the worktable, and the second positioning component includes two second telescopic cylinders fixedly disposed on the other side of the worktable. The output ends of the two second telescopic cylinders correspond to the two baffles respectively, and each output end of the second telescopic cylinder is fixedly provided with a push plate.

[0007] Furthermore, a horizontal plate is fixed to the top of the baffle, one end of the horizontal plate extends toward the push plate, a third telescopic cylinder is vertically fixed to the horizontal plate, the output end of the third telescopic cylinder extends through the horizontal plate toward the aluminum profile, and a pressure plate is fixed to the output end of the third telescopic cylinder.

[0008] Furthermore, nylon pads are fixedly provided on the side of the baffle, push plate, and pressure plate near the aluminum profile.

[0009] Furthermore, the fixed-length component includes a slidably mounted U-shaped frame on the output section. The sliding direction of the U-shaped frame is parallel to the moving direction of the aluminum profile. A fourth telescopic cylinder is fixedly mounted on the U-shaped frame. The free end of the fourth telescopic cylinder extends vertically through the top of the U-shaped frame towards the output section and is fixedly mounted with a positioning plate. A locking part for preventing the U-shaped frame from sliding is provided on one side of the U-shaped frame.

[0010] Furthermore, slide rods are fixed on both sides of the output section adjacent to the moving direction of the aluminum profile, and the bottom ends of the U-shaped frame are slidably connected to the two slide rods respectively. The locking part includes a first screw screwed to one side of the U-shaped frame, and one end of the first screw passes through one side of the U-shaped frame and abuts against the corresponding slide rod.

[0011] Furthermore, a measuring scale is provided on one side of the output section, and a pointer is fixed on one side of the length-fixing component corresponding to the measuring scale.

[0012] Furthermore, both the input section and the output section are roller conveyors, and each of the input section and the output section is equipped with a drive motor for driving the input section and the output section, respectively.

[0013] Furthermore, the conveying speed of the input segment is less than the conveying speed of the output segment.

[0014] Compared with the prior art, the beneficial effects of the fixed-length cutting device for aluminum profile processing provided in this application are: 1.

[0023] Please refer to the following: Figures 1 to 2 As shown, the following describes a fixed-length cutting device for aluminum profile processing provided in an embodiment of this application. This utility model provides a fixed-length cutting device for aluminum profile processing, comprising an input section 1, a cutting section 2, and an output section 3 sequentially connected along the moving direction of the aluminum profile 7. The input section 1 is used to transport the aluminum profile 7 into the cutting section 2, the cutting section 2 completes the cutting of the aluminum profile 7, and then the output section 3 transports the cut aluminum profile 7 to the next process. The cutting section 2 includes a worktable 21 and a cutting blade 22 rotatably mounted above the worktable 21. The cutting direction of the cutting blade 22 is perpendicular to the moving direction of the aluminum profile 7. In practice, the conveying section transports the aluminum profile 7 to below the cutting blade 22, and then the operator starts the cutting blade 22 to complete the cutting along a direction perpendicular to the moving direction of the aluminum profile 7.

[0024] Preferably, the cutting blade 22 includes a bracket 221, a blade 222 for cutting the aluminum profile 7 rotatably mounted at one end of the bracket 221, and a first motor 223 for driving the blade 222 to rotate. The end of the bracket 221 away from the blade 222 is rotatably connected to the top surface of the worktable 21. A side plate 211 is fixedly mounted on one side of the worktable 21, and a first telescopic cylinder 23 is provided between the side plate 211 and the bracket 221. The two ends of the first telescopic cylinder 23 are rotatably connected to the side plate 211 and the bracket 221, respectively. In practice, the first telescopic cylinder 23 extends or retracts, pushing the bracket 221 to rotate around the connection point with the worktable 21, thereby driving the blade 222 to descend to the cutting position. The first motor 223 drives the blade 222 to rotate, completing the cutting of the aluminum profile 7. After cutting is completed, the first telescopic cylinder 23 resets, driving the blade 222 to rise and leave the aluminum profile 7. By driving the bracket 221 to rotate through the first telescopic cylinder 23, the precise lifting and lowering of the blade 222 is achieved, avoiding the instability of manual operation and improving the reliability of the cutting process.

[0025] In this embodiment, both input section 1 and output section 3 employ existing roller conveyor lines, each driven by a drive motor 31. The rolling friction between the rollers and the aluminum profile 7 reduces conveying resistance, prevents surface wear on the aluminum profile 7, and ensures stable conveying. Preferably, the conveying speed of input section 1 is lower than that of output section 3. Because input section 1 is slower and output section 3 is faster, it prevents the aluminum profile 7 in cutting section 2 from accumulating due to inconsistent conveying speeds, ensuring smooth continuous production.

[0026] In this embodiment, a length-fixing component 4 for controlling the cutting length of the aluminum profile 7 is slidably disposed on the cutting section 2. The length-fixing component 4 precisely controls the cutting length, eliminating the need for repeated manual measurement and marking, thus improving the accuracy and efficiency of length-fixed cutting of the aluminum profile 7. Specifically, the length-fixing component 4 includes a U-shaped frame 41 and a fourth telescopic cylinder 42 vertically fixed to the top of the U-shaped frame 41. The U-shaped frame 41 is slidably disposed on the output section 3, and the sliding direction of the U-shaped frame 41 is parallel to the moving direction of the aluminum profile 7. The free end of the fourth telescopic cylinder 42 extends vertically through the top of the U-shaped frame 41 towards the output section 3 and is fixedly disposed on a positioning plate 43. A locking part 44 for preventing the U-shaped frame 41 from sliding is provided on one side.

[0027] During implementation, the sliding frame 41 is moved to the corresponding position according to the required cutting length, and then the position of the frame 41 is fixed by the locking part 44. Then the fourth telescopic cylinder 42 extends, driving the positioning plate 43 to descend to the height of contact with the aluminum profile 7. The aluminum profile 7 stops when it moves to abut against the positioning plate 43. At this time, the cutting blade 22 is located in the preset position of the aluminum profile 7. After the cutting is completed, the fourth telescopic cylinder 42 retracts, the positioning plate 43 rises, and the aluminum profile 7 is released to the output section 3.

[0028] Preferably, slide rods 45 are fixed on both sides of the output section 3 adjacent to the moving direction of the aluminum profile 7. The bottom ends of the U-shaped frame 41 are slidably connected to the two slide rods 45 respectively. The locking part 44 includes a first screw screwed to one side of the U-shaped frame 41. One end of the first screw passes through one side of the U-shaped frame 41 and abuts against the corresponding slide rod 45. The U-shaped frame 41 slides along the slide rods 45 to ensure stable movement and improve the accuracy of the fixed length position. By setting the screw and slide rod 45 to fix the U-shaped frame 41, the structure is simple and avoids accidental sliding of the U-shaped frame 41 during the fixed length process. Specifically, when adjusting the fixed length, the first screw is loosened to separate the first screw from the slide rod 45. At this time, the U-shaped frame 41 can be pushed to slide along the slide rod 45 to the target position. Then, the first screw is tightened so that one end of it abuts tightly against the slide rod 45, and the position of the U-shaped frame 41 is locked by friction.

[0029] Ideally, a measuring scale 32 is provided on one side of the output section 3. The scale of the measuring scale 32 is distributed along the moving direction of the aluminum profile 7. A pointer 411 is fixed on one side of the length fixing component 4 corresponding to the measuring scale 32. The position of the length fixing component 4 is determined by the pointer 411 pointing to the scale of the measuring scale 32. This allows the staff to quickly read and adjust the cutting length without the need for additional measuring tools, shortens the debugging time, and ensures that the cutting length is consistent across multiple batches of production.

[0030] In this embodiment, on the cutting section 2, a first positioning component 5 and a second positioning component 6 for fixing the aluminum profile 7 are respectively provided on both sides of the cutting blade 22. Specifically, the first positioning component 5 includes baffles 51 fixedly at intervals on one side of the worktable 21 (the baffles 51 are respectively located on both sides of the cutting blade 22 along the axial direction), and the second positioning component 6 includes two second telescopic cylinders 61 fixedly on the other side of the worktable 21. The output ends of the two second telescopic cylinders 61 correspond to the two baffles 51 respectively, and a push plate 62 is fixedly provided on the output end of each second telescopic cylinder 61.

[0031] During operation, after the aluminum profile 7 moves to the cutting position, the second telescopic cylinder 61 extends, driving the push plate 62 to move towards the baffle 51, clamping the aluminum profile 7 between the push plate 62 and the baffle 51 to achieve lateral fixation. After cutting, the second telescopic cylinder 61 retracts, the push plate 62 resets, and the aluminum profile 7 is released. The baffle 51 and the push plate 62 cooperate to clamp the aluminum profile 7 from both sides, preventing the profile from shifting laterally (perpendicular to the direction of movement) during cutting and ensuring accurate cutting position.

[0032] Preferably, a horizontal plate 52 is fixed to the top of the baffle 51, one end of which extends towards the push plate 62. A third telescopic cylinder 53 is vertically fixed to the horizontal plate 52, and the output end of the third telescopic cylinder 53 extends through the horizontal plate 52 towards the aluminum profile 7. A pressure plate 54 is fixed to the output end of the third telescopic cylinder 53. In practice, after the aluminum profile 7 is horizontally fixed by the baffle 51 and the push plate 62, the third telescopic cylinder 53 extends, driving the pressure plate 54 to descend and press against the top surface of the aluminum profile 7. After cutting, the third telescopic cylinder 53 retracts, the pressure plate 54 rises, and the profile is released. By adding vertical (pressure plate 54) fixation on the basis of horizontal (baffle 51 and push plate 62) fixation, the profile is prevented from bouncing upward due to vibration during cutting, further improving the fixation stability.

[0033] Preferably, nylon pads (not shown in the figure) are fixed on the side of the baffle 51, push plate 62, and pressure plate 54 near the aluminum profile 7. Due to the soft texture of nylon, surface scratches and indentations caused by direct contact between the metal baffle 51, push plate 62, and pressure plate 54 and the aluminum profile 7 are avoided, ensuring the appearance quality of the product. At the same time, the nylon pads have a moderate surface friction coefficient, which can enhance the clamping effect on the profile and reduce relative sliding after fixing.

[0034] In a specific implementation of this utility model, the roller of the input section 1 rotates under the drive of the drive motor 31, conveying the aluminum profile 7 to be cut to the cutting section 2. The output section 3 starts synchronously, and its conveying speed is slightly higher than that of the input section 1 to prevent the aluminum profile 7 from accumulating in the cutting section 2. At the same time, according to the preset cutting length, the operator observes the pointer 411 of the measuring scale 32 and the length fixing component 4 on one side of the output section 3, loosens the first screw on the girder 41, pushes the girder 41 to slide along the slide bar 45 to the target position, and then tightens the first screw to lock the girder 41. At this time, the positioning is completed. Subsequently, the fourth telescopic cylinder 42 extends, driving the positioning plate 43 to descend to the height of contact with the top surface of the aluminum profile 7, forming the positioning reference for the cutting length of the aluminum profile 7. Aluminum profile 7 enters cutting section 2 via input section 1 and stops when it comes into contact with positioning plate 43 (at which point the preset cutting length is reached). Then, the second telescopic cylinder 61 extends, driving the push plate 62 to move towards the baffle 51, which, together with the baffle 51, clamps the aluminum profile 7 laterally. At the same time, the third telescopic cylinder 53 on the horizontal plate 52 extends, causing the pressure plate 54 to descend and press the top surface of the aluminum profile 7 vertically, thus achieving three-dimensional fixation of the aluminum profile 7 (horizontal + vertical). The nylon pads that contact the baffle 51, push plate 62, and pressure plate 54 directly adhere to the surface of the profile. Next, the first telescopic cylinder 23 of the cutting blade 22 extends, pushing the bracket 221 to rotate around the connection point of the worktable 21, causing the blade 222 to descend to the cutting position and complete the cutting along the direction perpendicular to the movement of the aluminum profile 7. After the cutting is completed, the first telescopic cylinder 23 retracts, and the blade 222 rises to reset. At the same time, the third telescopic cylinder 53 retracts, causing the pressure plate 54 to rise, and the second telescopic cylinder 61 retracts, causing the push plate 62 to reset, releasing the aluminum profile 7. At this time, the cut aluminum profile 7 is quickly conveyed to the next process under the drive of the output section 3, while the input section 1 continuously conveys the next section of aluminum profile 7 to be cut, entering the next cycle.

[0035] This utility model solves the problems of large errors and low efficiency of traditional manual measurement and marking by using the fixed-length component 4. The sliding rod 45 and the first screw work together to ensure the stability of the fixed-length position and strong consistency in multiple batches of production. The first positioning component 5 and the second positioning component 6 on both sides of the cutting blade 22 form a three-dimensional fixation, which completely avoids the displacement, shaking or bouncing of the aluminum profile 7 during cutting, ensuring that the cut surface is flat and burr-free, and eliminating the safety hazards caused by the loosening of the aluminum profile 7. By setting up a push plate 62 and a pressure plate 54 driven by a second telescopic cylinder 61 and a third telescopic cylinder 53, the adaptability of the equipment is enhanced to accommodate aluminum profiles 7 with different widths and thicknesses. It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0036] The above description is only a preferred embodiment of the present utility model and is 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.
