Description

Technical Field

[0001] This invention relates to the field of aluminum profile processing technology, specifically to an aluminum profile cutting device and control method. Background Technology

[0002] Aluminum profiles, as a typical representative of lightweight materials, are increasingly widely used in building curtain walls, new energy vehicles, rail transportation, and other fields. The precision of their cutting directly affects the subsequent assembly quality and product performance. Traditional aluminum profile cutting equipment generally uses manual pushing and positioning methods. Especially when processing profiles longer than 6 meters, multiple people are required to work together to complete feeding, centering, and positioning. This not only results in high labor intensity but also leads to cutting position deviations of ±2mm or more due to human error, posing safety hazards such as profile slippage and accidental tool damage. Existing equipment mostly achieves positioning through fixed limit blocks or single lead screw adjustments, but this is difficult to adapt to the processing needs of profiles with different cross-sectional specifications (e.g., from 40mm×40mm to 200mm×120mm). Frequent changes of tooling and fixtures result in downtime exceeding 30%. Furthermore, long profiles are prone to bending deformation during cutting due to the lack of continuous support, causing cut flatness errors exceeding 0.5mm and reducing tool life to less than 300 cuts.

[0003] Taking the "Aluminum Profile Cutting Equipment" (publication number CN213224508U) as an example, this equipment achieves fixed-length cutting through a belt conveyor mechanism and a limit plate driven by a lead screw. While this solves the efficiency problem of manual measurement, it has the following limitations: First, relying solely on a single lead screw to adjust the position of the limit plate makes it impossible to achieve synchronous centering of both sides of the profile. When the profile cross-sectional width changes by more than 20%, the positioning deviation can reach ±1.2mm. Second, the guide wheel assembly is driven by an independent motor, failing to form a continuous transmission chain. This makes it prone to slippage when the conveying speed exceeds 1.5m / s, leading to fluctuations in the cutting position. Third, the contact surface between the support block and the profile is rigid, lacking a buffer structure. This can easily cause material deformation when cutting thin-walled profiles (wall thickness ≤1.2mm), resulting in burr heights exceeding 0.3mm. Although this equipment performs stably in processing small and medium-sized profiles, it still requires manual support when dealing with 12-meter-long profiles used for new energy vehicle battery trays, making it difficult to meet the fully automated requirements of intelligent manufacturing production lines.

[0004] The core pain point of existing technologies lies in the failure to achieve integrated and coordinated control of "positioning-supporting-conveying": the positioning mechanism and the conveying system are independent of each other, which easily leads to secondary positioning errors; the support structure lacks adaptive adjustment capabilities and cannot match the rigidity requirements of profiles with different cross-sections; the transmission system mostly uses segmented drive, which makes it difficult to ensure synchronization during long-distance conveying. This invention achieves automatic alignment of profiles through a motor-driven bidirectional screw mechanism, combined with a belt-driven continuous guide wheel set and an adjustable-pitch clamping and positioning frame, specifically addressing the above pain points. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an aluminum profile cutting device and control method, which solves the problem that existing technologies cannot achieve integrated and coordinated control of positioning, support, and conveying.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: an aluminum profile cutting device, including a workbench, two mounting frames fixedly connected above the workbench, a bracket mounted on the top of the mounting frame, a positioning frame fixedly connected to the top of the bracket, a clamping groove penetrating through the interior of the positioning frame, a clamping plate two fixedly connected to the top of the inner side of the clamping groove, a cylinder two fixedly connected to the interior of the bracket, and a clamping plate one fixedly connected to the extension end of the cylinder two through the clamping groove.

[0009] The workbench has support brackets fixedly connected to both outer ends, and a guide platform fixedly connected to the top of the support brackets. A slot is formed on the bottom inner side of the guide platform. A motor is fixedly connected to the right outer end of the guide platform. A bidirectional screw is rotatably connected inside the slot. The output end of the motor is connected to the bidirectional screw. Two connecting plates are threaded onto the bidirectional screw, and U-shaped brackets are fixedly connected to the inner ends of both connecting plates.

[0010] The U-shaped frame has several guide wheels rotatably connected inside. A drive box is fixedly connected to the top of the left side of the U-shaped frame. A second motor is fixedly connected to one end of the drive box. A main shaft is installed at both ends of the outermost guide wheel and is rotatably connected inside the U-shaped frame. The main shaft is fixedly connected to the output end of the second motor and a pulley is fixedly connected to the main shaft. A driven shaft is installed at both ends of the adjacent guide wheel and is also rotatably connected to the U-shaped frame. Two second pulleys are fixedly connected to the driven shaft. A belt is fitted on the first and second pulleys. Two connecting blocks are fixedly connected below the guide platform. A sliding rod is fixedly connected inside the connecting block, and the connecting plate is slidably connected to the sliding rod.

[0011] Preferably, a limiting block is fixedly connected to the bottom of the bracket, and a limiting groove is formed on the top of the mounting bracket, with the limiting block and the limiting groove corresponding to each other.

[0012] Preferably, the mounting bracket has rotating handles rotatably connected to both outer ends, and mounting slots are provided at both upper ends of the mounting bracket.

[0013] Preferably, a bevel gear box is fixedly connected to one end of the inner side of the mounting groove, the rotating handle is connected to the transverse bevel gear inside the bevel gear box, a screw is rotatably connected inside the bevel gear box, a longitudinal bevel gear is fixedly connected to the screw, and the transverse bevel gear and the longitudinal bevel gear mesh with each other.

[0014] Preferably, the screw is threaded with a positioning block, and the limiting block has a positioning groove inside, with the positioning block and the positioning groove corresponding to each other.

[0015] Preferably, a crossbeam is fixedly connected to the rear end of the workbench, and a cylinder is fixedly connected to the top of the crossbeam.

[0016] Preferably, a cutting disc is fixedly connected to the extended end of the cylinder one through downwards, a motor one is fixedly connected to one outer end of the cutting disc, and a cutting blade is fixedly connected to the output end of the motor one.

[0017] A control method for an aluminum profile cutting device includes the following control cutting steps:

[0018] S1. Pass the aluminum profile to be cut through the interior of the two positioning frames in sequence, so that its upper end contacts the second clamping plate. Then, start the second cylinder to drive the first clamping plate to move upward. With the help of the second clamping plate, the positioning and clamping of the aluminum profile can be completed.

[0019] S2. Then, the staff starts motor three to drive the double screw to rotate. Under the action of the threaded engagement, the two connecting plates can drive the U-shaped frame to move inward, so that the inner guide wheel contacts the two ends of the aluminum profile. Then, the motor two on the upper left end is started to drive the internal main shaft and pulley one to rotate. Through the transmission between the belts, multiple shafts can be rotated to ensure the stable rotation of the guide wheel, so that the guide wheel can transport the aluminum profile and ensure that the cutting position of the aluminum profile is consistent with the cutting blade at the top, avoiding the complexity of manual adjustment when the aluminum profile is long.

[0020] S3. During cutting, start the top cylinder to drive the cutting blade downward so that the cutting blade can contact the aluminum profile at the bottom. Then start the motor to drive the cutting blade to rotate. The cutting blade can complete the fast cutting operation of the aluminum profile.

[0021] S4. When the positioning clamping assembly needs to be replaced, rotating the handles at both ends of the mounting bracket can drive the transverse bevel gear inside the bevel gear box to rotate. Under the meshing action, the longitudinal bevel gear and the screw will rotate. Then, under the action of the threaded engagement, the positioning block can gradually retract inward. At this time, the positioning block leaves the inside of the positioning groove, and the staff can directly remove the positioning bracket from the top of the mounting bracket.

[0022] (III) Beneficial Effects

[0023] This invention provides an aluminum profile cutting device and control method. It has the following beneficial effects:

[0024] 1. This invention significantly improves processing efficiency and precision in the field of aluminum profile cutting. It features a uniquely designed guiding component. Traditional equipment relies on manual pushing and positioning when processing long profiles, which is prone to deviations and safety hazards. This invention uses a motor-driven bidirectional screw mechanism to synchronously adjust the guide wheel sets on both sides, achieving automatic centering and stable clamping of the profile. Multiple sets of belt-driven guide wheels form a continuous conveying structure, ensuring that the profile is accurately fed to the cutting position. This not only completely replaces manual pushing but also ensures the consistency of the cutting position through mechanical automation, greatly reducing positioning errors and operational intensity when processing long materials.

[0025] 2. The synergistic design of the guide component and the overall structure of this invention further amplifies the technical advantages. The guide wheel assembly has both support and conveying functions. Combined with the adjustable-spacing clamping and positioning frame, the equipment can adapt to the processing of profiles of different specifications. During the cutting process, both ends of the profile are always in a state of rigid support and controllable movement, effectively suppressing vibration and deformation, thereby improving the cut quality and tool life. This integrated guide solution solves the technical problem of "positioning-support-conveying" linkage in the processing of long profiles, and provides the industry with a high-stability and low-energy-consumption cutting solution.

[0033] 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.

[0034] Example:

[0035] like Figure 1-6 As shown, this embodiment of the invention provides an aluminum profile cutting device, including a workbench 1. Two mounting brackets 3 are fixedly connected to the top of the workbench 1. A support 4 is installed on the top of the mounting brackets 3. A positioning bracket 2 is fixedly connected to the top of the support 4. A clamping groove is provided through the inside of the positioning bracket 2. A clamping plate 37 is fixedly connected to the top of the inner side of the clamping groove. A cylinder 22 is fixedly connected to the inside of the support 4. The extension end of the cylinder 22 passes through the clamping groove and is fixedly connected to a clamping plate 26. Activating the cylinder 22 can drive the clamping plate 37 to move upward. With the cooperation of the clamping plate 26, the aluminum profile can be quickly positioned and clamped. The distance between the two positioning brackets 2 is relatively short. Through clamping, the position to be cut can be better fixed, improving the stability during cutting.

[0036] The workbench 1 has a support frame 11 fixedly connected to both outer ends. The top of the support frame 11 is fixedly connected to the guide table 10. The bottom of the inner side of the guide table 10 has a slot 17. The right side of the outer side of the guide table 10 is fixedly connected to the motor 21. The slot 17 is rotatably connected to the double screw 18. The output end of the motor 21 is connected to the double screw 18. The double screw 18 has two connecting plates 14 threaded on it. The inner ends of the two connecting plates 14 are fixedly connected to U-shaped frames 15. By setting the guide table 10, the two ends of the aluminum profile can be supported. In addition, the guide wheels 16 at both inner ends can stably transport it, which can greatly reduce the labor intensity of the workers. After the cutting is completed, it can also transport one end. When processing long aluminum profiles, it can save time and effort.

[0037] Several guide wheels 16 are rotatably connected inside the U-shaped frame 15. A drive box 13 is fixedly connected to the top of the left side of the U-shaped frame 15. A second motor 12 is fixedly connected to one end of the drive box 13. A main shaft 32 is installed at both ends of the outermost guide wheel 16 and is rotatably connected inside the U-shaped frame 15. The main shaft 32 is fixedly connected to the output end of the second motor 12, and a pulley 33 is fixedly connected to the main shaft 32. A driven shaft 36 is installed at both ends of the adjacent guide wheel 16 and is also rotatably connected to the U-shaped frame 15. Two second pulleys 35 are fixedly connected to the driven shaft 36. A belt 34 is fitted on the first pulley 33 and the second pulley 35. Two connecting blocks 20 are fixedly connected to the bottom of the guide table 10. The connecting block 20 is internally fixedly connected to a slide rod 19, and the connecting plate 14 is slidably connected to the slide rod 19. The starting motor 21 drives the bidirectional screw 18 to rotate. Under the action of the threaded engagement, the two connecting plates 14 can drive the U-shaped frame 15 to move inward, so that the inner guide wheel 16 contacts the two ends of the aluminum profile. Then, the starting motor 12 on the upper left end drives the internal main shaft 32 and the pulley 33 to rotate. Through the transmission between the belts 34, the rotation of multiple slave shafts 36 can be realized to ensure the stable rotation of the guide wheel 16, thereby enabling the guide wheel 16 to transport the aluminum profile and ensure that the cutting position of the aluminum profile is consistent with the cutting blade 7 at the top, avoiding the complexity of manual adjustment when the aluminum profile is long.

[0038] A limiting block 25 is fixedly connected to the bottom of the bracket 4, and a limiting groove 27 is opened on the top of the mounting bracket 3. The limiting block 25 and the limiting groove 27 correspond to each other. Rotating handles 24 are rotatably connected to both ends of the outer side of the mounting bracket 3. Mounting grooves 31 are opened at both ends of the upper part of the mounting bracket 3. A bevel gear box 28 is fixedly connected to one end of the inner side of the mounting groove 31. The rotating handle 24 is connected to the transverse bevel gear inside the bevel gear box 28. A screw 30 is rotatably connected inside the bevel gear box 28. A longitudinal bevel gear is fixedly connected to the screw 30. The transverse bevel gear and the longitudinal bevel gear mesh with each other. The upper thread is fitted with a positioning block 29, and the interior of the limiting block 25 is provided with a positioning groove 23. The positioning block 29 and the positioning groove 23 correspond to each other. The interior of the bevel gear box 28 is equipped with a horizontal and vertical bevel gear assembly. The two work together to achieve a transmission effect, ensuring that when the operator turns the rotating handle 24 at the bottom, the internal screw 30 can be driven to rotate. At the same time, the retraction and extension of the positioning block 29 are controlled. It works in conjunction with the positioning groove 23 inside the limiting block 25, which makes it easy for the operator to disassemble and assemble the positioning frame 2, replace different sized clamps, and improve the applicability of the device.

[0039] A crossbeam 9 is fixedly connected to the rear end of the workbench 1. A cylinder 8 is fixedly connected to the top of the crossbeam 9. A cutting disc 6 is fixedly connected downward through the extension end of the cylinder 8. A motor 5 is fixedly connected to one outer end of the cutting disc 6. A cutting blade 7 is fixedly connected to the output end of the motor 5. When cutting, the cylinder 8 at the top is started to drive the cutting blade 7 to move downward, so that the cutting blade 7 can contact the aluminum profile at the bottom. Then, the motor 5 is started to drive the cutting blade 7 to rotate. The cutting blade 7 can complete the rapid cutting operation of the aluminum profile.

[0040] Working principle: The aluminum profile to be cut is passed through the interior of the two positioning frames 2 in sequence, so that its upper end contacts the clamping plate 37. Then, the cylinder 22 is started, which can drive the clamping plate 26 to move upward. Together with the clamping plate 37, the aluminum profile can be positioned and clamped.

[0041] Subsequently, the staff started motor 321 to drive the bidirectional screw 18 to rotate. Under the action of the threaded engagement, the two connecting plates 14 can drive the U-shaped frame 15 to move inward, so that the inner guide wheel 16 contacts the two ends of the aluminum profile. Then, the motor 212 on the upper left end is started to drive the internal main shaft 32 and pulley 13 to rotate. Through the transmission between the belts 34, the rotation of multiple slave shafts 36 can be realized to ensure the stable rotation of the guide wheel 16, so that the guide wheel 16 can transport the aluminum profile and ensure that the cutting position of the aluminum profile is consistent with the cutting blade 7 at the top, avoiding the complexity of manual adjustment when the aluminum profile is long.

[0042] During cutting, the top cylinder 8 is activated to drive the cutting blade 7 downward, so that the cutting blade 7 can contact the aluminum profile at the bottom. Then, the motor 5 is activated to drive the cutting blade 7 to rotate, and the cutting blade 7 can complete the rapid cutting operation of the aluminum profile.

[0043] When the positioning clamping assembly needs to be replaced, rotating the handles 24 at both ends of the mounting bracket 3 can drive the transverse bevel gear inside the bevel gear box 28 to rotate. Under the meshing action, the longitudinal bevel gear and the screw 30 will rotate. Then, under the action of the threaded engagement, the positioning block 29 can gradually retract inward. At this time, the positioning block 29 leaves the inside of the positioning groove 23, and the staff can directly remove the positioning bracket 2 from the top of the mounting bracket 3.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
