Description

Technical Field

[0001] This invention relates to the field of aluminum profile cutting technology, and more specifically to an aluminum profile cutting device that prevents extrusion deformation. Background Technology

[0002] Aluminum profiles, also known as aluminum and aluminum alloy profiles, are metal basic components made from pure aluminum or aluminum alloy as raw materials through plastic forming processes such as hot extrusion, cold drawing, rolling, and cold bending. They have a constant cross-sectional shape, uniform dimensional tolerances, and are continuous long strips. They are the most widely used core basic materials in lightweight manufacturing, industrial automation, and construction engineering. According to the cross-sectional structure, they can be divided into: solid aluminum profiles, hollow aluminum profiles, composite structure aluminum profiles, and custom-made aluminum profiles.

[0003] Hollow aluminum profiles, especially hollow aluminum tubes, have inherent low rigidity and high risk of instability. Therefore, during actual cutting, hollow aluminum profiles are very prone to deformation, especially at the cut, due to the superposition of multiple factors such as mechanical clamping force and dynamic cutting force.

[0004] Currently, the common solution to the problem of deformation that may occur during the cutting of hollow aluminum tubes is to use a non-rigid clamping structure to clamp the hollow aluminum tube and adjust the cutting blade's feed speed. However, these adjustments only reduce the degree of deformation caused by the cutting force and clamping force on the hollow aluminum tube from the outside, resulting in a very limited effect in preventing extrusion deformation. Therefore, this application proposes an aluminum profile cutting device to prevent extrusion deformation, thereby solving the above-mentioned problem. Summary of the Invention

[0005] This invention provides an aluminum profile cutting device that prevents extrusion deformation, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An aluminum profile cutting device resistant to extrusion deformation includes an operating table, a pusher support, a cutting blade, and an aluminum profile. The aluminum profile is placed on the operating table and the pusher support. A protective cover is movably connected to the operating table. The cutting blade is disposed inside the operating table, and a cutting groove is formed on the operating table. The cutting blade extends through the cutting groove to the outside of the operating table to cut the aluminum profile placed on the operating table. An extension base is connected to the side of the operating table away from the pusher support. Multiple telescopic rods are fixedly connected to the extension base. A base plate is fixedly connected to the output end of each telescopic rod, and a base platform is movably connected to the base plate.

[0007] Multiple telescopic positioning components are movably connected to the base platform. One end of each telescopic positioning component extends into the interior of the aluminum profile to position and prevent crushing of the aluminum profile to be cut.

[0008] The base platform rotates along the base plate, causing the shorter aluminum profile, after being cut, to detach from the operating table and protective cover.

[0009] A further improvement of the technical solution of the present invention is that: each of the telescopic positioning components includes a telescopic rod 2, the output end of the telescopic rod 2 is fixedly connected to a grid frame, a driving device 3 is fixedly installed inside the grid frame, a fixing block is fixedly connected to one end of the output shaft of the driving device 3 extending to the outside of the grid frame, and two telescopic rods 4 are fixedly connected to the fixing block. The output ends of the two telescopic rods 4 are in opposite directions, and a support roller is fixedly connected to the output end of each telescopic rod 4. The farthest distance between the two support rollers is adapted to the inner diameter of the aluminum profile.

[0010] A further improvement of the technical solution of the present invention is that: a plurality of sliding grooves are provided on the base platform, a plurality of sliders are movably connected to the inner wall of each sliding groove, and a slot is provided on each slider; an insert is fixedly connected to the telescopic rod II, and the insert is movably connected to the slot.

[0011] A further improvement of the technical solution of the present invention is that: in one of the sliding grooves, multiple sliders movably connected inside are threadedly connected to a drive screw, and the two ends of the drive screw are movably connected to the inner wall of the sliding groove; in the other sliding groove, multiple sliders movably connected inside are threadedly connected to a slide rail, and the two ends of the slide rail are fixedly connected to the inner wall of the sliding groove.

[0012] A further improvement of the technical solution of the present invention is that a telescopic rod three and a baffle are fixedly connected to the telescopic rod two.

[0013] When multiple aluminum profiles are cut simultaneously in a single layer, the installation positions of the telescopic rods and baffles on two adjacent telescopic positioning components are staggered.

[0014] A further improvement of the technical solution of the present invention is that: a blade is fixedly connected to one end of the output shaft of the drive device three that extends to the outside of the grid frame.

[0015] A further improvement of the technical solution of the present invention is that: there are two base platforms, which are fixedly connected by a connecting block. The connecting block is rotatably connected to the base plate by a rotating shaft, and multiple telescopic positioning components that are movably connected on the two base platforms are symmetrically arranged about the center of the rotating shaft.

[0016] A further improvement of the technical solution of the present invention is that: a side baffle is fixedly connected to one side of the base platform, and the length of the side baffle is the same as the length of the grid frame and the supporting roller.

[0017] A storage cart is provided on the side of the extended base away from the operating table, and the upper surface of the storage cart is lower than the lower surface of the base plate.

[0018] A further improvement of the technical solution of the present invention is that: when multiple aluminum profiles need to be cut in multiple layers simultaneously, multiple vertical mounting plates are fixedly connected to the outer circumference of each telescopic rod 2, and a telescopic rod 5 is fixedly connected to each vertical mounting plate. The output end of the telescopic rod 5 connected to the bottom telescopic rod 2 is movably connected to the vertical mounting plate connected to the outer circumference of the top telescopic rod 2. The telescopic rod 5 connected to the bottom telescopic rod 2 pushes the top telescopic rod 2 to rise, so as to adapt to the cutting of aluminum profiles of different diameters.

[0019] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides an aluminum profile cutting device that prevents extrusion deformation. When the distance between the two support rollers is at its minimum, the two support rollers are first pushed to a position close to one side of the cutting groove by the telescopic rod 2. Then, the aluminum profile is pushed in so that the aluminum profile covers the two support rollers. Then, the two support rollers are unfolded to abut against the inner wall of the aluminum profile. At this time, the telescopic positioning component can play the role of positioning, guiding and auxiliary fixing, so that the aluminum profile will not have a positional deviation problem during the pushing and cutting process.

[0020] 2. The present invention provides an aluminum profile cutting device that prevents extrusion deformation. When the two support rollers are pushed to a position that fits against one side of the cutting groove and form a rotation support, they support the aluminum profile at the edge of the cut, reducing the possibility of cutting deformation at the cut of the aluminum profile or weakening the degree of cutting deformation.

[0021] 3. This invention provides an aluminum profile cutting device to prevent extrusion deformation. When the support roller unfolds and abuts against the inner wall of the aluminum profile, and after the aluminum profile is cut, the friction between the support roller and the aluminum profile, as well as the radial force generated when the support roller unfolds, allows the support roller to maintain a connection with the aluminum profile. Then, the telescopic positioning component, the base platform, and the cut aluminum profile sleeved on the support roller rotate along the base plate to a position where they are disengaged from the cutting groove. This facilitates the processing of the cut profile and avoids the problem of the cut profile accumulating in the cutting groove, which would otherwise require additional manual processing.

[0024] The present invention will be further described in detail below with reference to embodiments: Example

[0025] like Figure 1-10As shown, this invention provides an aluminum profile cutting device to prevent extrusion deformation, including an operating table 1, a pushing support 3, a cutting blade 4, and an aluminum profile 5. The aluminum profile 5 in this application is a hollow round tube. The aluminum profile 5 is placed on the operating table 1 and the pushing support 3. A protective cover 2 is movably connected to the operating table 1. The operating table 1, protective cover 2, pushing support 3, cutting blade 4, and aluminum profile 5 are all prior art, used to push the aluminum profile 5 according to a predetermined cutting length. A vertical clamping assembly for constraining the vertical position of the aluminum profile 5 and a horizontal clamping assembly for constraining the lateral position of the aluminum profile 5 are also provided between the operating table 1 and the protective cover 2. Both the vertical clamping assembly and the horizontal clamping assembly are prior art, used to fix the position of the aluminum profile 5 to be cut and directly contact the aluminum profile. The part in contact with the profile 5 is made of soft material to reduce the effect of clamping force on the deformation of the aluminum profile 5. The cutting blade 4 is set inside the operating table 1 and includes a drive structure and a heat dissipation structure. The drive structure and the heat dissipation structure are existing technologies. The drive structure is used to drive the cutting blade 4 to rotate and move vertically or horizontally along the cutting groove to cut the aluminum profile 5. The operating table 1 has a cutting groove. The cutting blade 4 extends through the cutting groove to the outside of the operating table 1 to cut the aluminum profile 5 placed on the operating table 1. An extension base 6 is connected to the side of the operating table 1 away from the push support 3. Multiple telescopic rods 7 are fixedly connected to the extension base 6. The output end of the telescopic rods 7 is fixedly connected to the base plate 30. A base platform 9 is movably connected to the base plate 30.

[0026] Multiple telescopic positioning components are movably connected to the base platform 9. One end of each telescopic positioning component extends into the interior of the aluminum profile 5 to position and prevent crushing of the aluminum profile 5 to be cut. The spacing between each telescopic positioning component can be adjusted in real time according to the diameter of the aluminum profile 5.

[0027] When the diameter of the aluminum profile 5 to be cut changes, the position of the aluminum profile 5 with different diameters can be fixed and cut by means of the telescopic rod 7 and the spacing between the telescopic positioning components.

[0028] The base platform 9 rotates along the base plate 30, causing the shorter aluminum profile 5, after being cut, to detach from the operating table 1 and the protective cover 2.

[0029] First, confirm the quantity of aluminum profiles 5 for a single cut and install the corresponding number of telescopic positioning components on the base platform 9. Then, fix the position of the aluminum profiles 5 using vertical and horizontal clamping components. Simultaneously, one end of the telescopic positioning component extends into the aluminum profile 5 and aligns with the side of the cutting groove closest to the extension base 6. The distance the aluminum profile 5 extends to the side of the cutting groove is the required cutting distance. At this point, the telescopic positioning component supports the cutting edge of the aluminum profile 5 from inside, ensuring anti-extrusion deformation and avoiding severe cutting deformation. Next, the drive structure drives the cutting blade 4 to rotate and advance along the cutting groove until the aluminum profile 5 is cut. Once completed, the vertical and horizontal clamping components release their constraints on the aluminum profile 5. The uncut aluminum profile 5 continues to advance the distance to be cut, while the cut aluminum profile 5 follows the telescopic positioning component and the base platform 9 to rotate along the base plate 30. Currently, when cutting a longer profile into multiple shorter profiles, after the profile itself is cut, the cut profile is pushed out of the cutting equipment by the continuous advancement of the longer profile. The cut profile will accumulate outside the cutting groove, causing a mess on the production site. However, the technical solution of this application can avoid the accumulation of the cut shorter profiles near the cutting groove. After the cut aluminum profile 5 is unloaded, subsequent cutting operations can be carried out.

[0030] It also includes a PLC control system and other related equipment, which are electrically connected to each electrical control device in this application to ensure the real-time performance and accuracy of control commands and to adapt to the continuous operation requirements of each structure in this application.

[0031] Furthermore, each telescopic positioning component includes a telescopic rod 214, which is existing technology and includes pneumatic, electric, and other drive methods. The output end of the telescopic rod 214 is fixedly connected to a grid frame 24. The grid frame 24 has a drive device 325 fixedly installed inside. The drive device 325 is existing technology and includes a motor and other equipment and related accessories. The output shaft of the drive device 325 extends to one end outside the grid frame 24 and is fixedly connected to a fixing block 26. Two telescopic rods 427 are fixedly connected to the fixing block 26. The telescopic rods 427 are existing technology and include pneumatic, electric, and other drive methods. The output ends of the two telescopic rods 427 are in opposite directions. The output end of each telescopic rod 427 is fixedly connected to a support roller 28. The farthest distance between the two support rollers 28 is adapted to the inner diameter of the aluminum profile 5.

[0032] Initially, telescopic rod 4 27 is inactive, and the maximum distance between the two support rollers 28 is at its minimum. This corresponds to the minimum inner diameter of the aluminum profile 5, which is r. The actual inner diameter of the aluminum profile 5 to be cut is R (R>r). First, telescopic rod 1 7 moves the telescopic positioning assembly upwards by a distance Rr. Then, the telescopic positioning assembly moves laterally by a distance Rr, making the midpoint line of the distance between the two support rollers 28 collinear with the central axis of the aluminum profile 5 to be cut. The aluminum profile 5 is then pushed to the desired cutting distance. Next, telescopic rod 2 14 operates, pushing telescopic rod 4 27 and the two support rollers 28 to a position where one side of the support rollers 28 contacts the cutting groove. At this point, both telescopic rods 4 27 operate simultaneously, pushing the two support rollers 28 to move in opposite directions. Until the two support rollers 28 abut against the inner wall of the aluminum profile 5, this is a static support effect. When the drive device 3 25 drives the two support rollers 28 to rotate along the inner wall of the aluminum profile 5, a rotational support effect is formed, which minimizes the deformation of the cut on one side of the aluminum profile 5 during cutting and ensures the cutting quality. At the same time, after the aluminum profile 5 is cut, the two telescopic rods 4 27 push the axial force generated at the point where the support rollers 28 abut against the inner wall of the cut aluminum profile 5, so that when the base platform 9 drives the telescopic rod 2 14 to rotate, the cut aluminum profile 5 moves with the two open support rollers 28 to a position away from the cutting groove, avoiding the accumulation of the cut aluminum profile 5 at the cutting groove and causing a messy production site.

[0033] At this time, when the output ends of the two telescopic rods 27 drive the two support rollers 28 to retract, the axial force generated by the two support rollers 28 on the aluminum profile 5 disappears, and the cut aluminum profile 5 is hung on the support rollers 28. At this time, it is convenient to remove the cut aluminum profile 5 and store it in a centralized manner.

[0034] After the position of the support rollers 28 is determined, the two support rollers 28 are first pushed to the position closest to the cutting groove by the telescopic rod 2 14, and then the aluminum profile 5 is pushed in so that the aluminum profile 5 covers the two support rollers 28. The telescopic rod 4 27 pushes the support rollers 28 to a distance that matches the inner diameter of the aluminum profile 5. At this time, the two support rollers 28 can also play a positioning role, so that the position of the aluminum profile 5 to be cut is fixed. In this case, the force of the vertical clamping component and the horizontal clamping component does not need to be very large, so that the aluminum profile 5 will not shift during the cutting process, which will affect the cutting effect.

[0035] The maximum stroke of the telescopic rod 14 is the maximum cutting length of the aluminum profile 5 that it can be used for, and the maximum stroke of the two support rollers 28 is the maximum inner diameter of the aluminum profile 5 that it can be used for.

[0036] Furthermore, the base platform 9 has multiple sliding grooves 11, and multiple sliders 12 are movably connected to the inner wall of each sliding groove 11. Each slider 12 has a slot 18. An insert 19 is fixedly connected to the telescopic rod 14. The insert 19 is movably connected to the slot 18. Multiple sliders 12 can be installed with multiple telescopic rods 14, that is, multiple telescopic positioning components, corresponding to multiple aluminum profiles 5 to be cut. The number of telescopic positioning components can be selectively installed according to actual needs.

[0037] Furthermore, locking grooves 20 are provided on both sides of the insert block 19, and corresponding locking balls 21 are provided on the inner wall of the slot 18. The locking balls 21 are movably connected inside the locking balls 21, and elastic balls 23 are movably connected between the locking balls 21 and the inner wall of the movable cavity 22. The elastic balls 23 are made of elastic material or replaced by springs. The locking balls 21 extend to the outside of the movable cavity 22 through the elastic balls 23 and form a locking engagement with the locking grooves 20. When the insert block 19 enters and exits the slot 18, the insert block 19 will exert a squeezing effect on the locking balls 21, causing the elastic balls 23 to undergo elastic deformation. This can ensure the connection stability between the telescopic rod 14 and the slider 12, and also facilitate the disassembly and assembly of the telescopic rod 14 according to the actual number of aluminum profiles 5 to be cut, so as to match them.

[0038] Furthermore, multiple sliders 12 movably connected inside one of the slide grooves 11 are threadedly connected to a drive screw 13, with both ends of the drive screw 13 movably connected to the inner wall of the slide groove 11. Multiple sliders 12 movably connected inside another slide groove 11 are threadedly connected to a slide rail 35, with both ends of the slide rail 35 fixedly connected to the inner wall of the slide groove 11. A clamp is provided between the slider 12 and the slide rail 35. The clamp is existing technology and is used to limit the sliding position and distance of the slider 12 along the drive screw 13 and the slide rail 35. When the connection between the slider 12 and the slide rail 35 is locked under the action of the clamp, the other... The slider 12 at the corresponding position on the drive screw 13 is threadedly connected to the drive screw 13, but only rotates, while the position of the telescopic positioning component corresponding to the two sliders 12 does not change. Through the action of the clamp, the distance between multiple sliders 12 can be adjusted according to actual needs. The base platform 9 is externally fixedly connected to the drive device 2 17. The output shaft of the drive device 2 17 is fixedly connected to the drive screw 13. The drive device 2 17 is existing technology and includes equipment such as motors and related accessories to drive the drive screw 13 to rotate, thereby moving the sliders 12 along the drive screw 13 to different positions.

[0039] Furthermore, a telescopic rod 15 and a baffle 16 are fixedly connected to the telescopic rod 2 14. The telescopic rod 3 15 and the baffle 16 are set separately. The telescopic rod 3 15 is existing technology and includes pneumatic, electric and other drive methods.

[0040] When multiple aluminum profiles 5 are cut simultaneously in a single layer, the installation positions of the telescopic rods 15 and baffles 16 on two adjacent telescopic positioning assemblies are staggered.

[0041] In the initial stage, one of the telescopic positioning components is located at the outermost edge of the slide 11, and the two support rollers 28 are not extended. At this time, the inner diameter of the corresponding aluminum profile 5 is r, with a minimum of r. The actual inner diameter of the aluminum profile 5 to be cut is R (R>r). Depending on the number of aluminum profiles 5 to be cut in different single layers, there are different operating methods: 1. When there is only one aluminum profile 5 to be cut, there is only one telescopic positioning component. First, the telescopic rod 17 drives the base plate 30 and the telescopic positioning component installed on it to move upward by a distance Rr. The drive screw 13 rotates and drives the telescopic positioning component to move laterally by a distance Rr, so that the midpoint line of the distance between the two support rollers 28 on the telescopic positioning component is collinear with the central axis of the aluminum profile 5 to be cut. Then, the telescopic rod 24 pushes the two support rollers 28 to move to one side of the cutting groove. Then, the aluminum profile 5 is pushed in so that the aluminum profile 5 covers the two support rollers 28. At this time, the two telescopic rods 47 push the support rollers 28 to unfold until the support rollers 28 abut against the inner wall of the aluminum profile 5. Continue to push the aluminum profile 5 to the length to be cut. The cutting blade 4 is used to complete the cutting of the aluminum profile 5. 2. When there are multiple aluminum profiles 5 to be cut, and it is a single-layer cut, firstly, select the corresponding number of telescopic positioning components and install them on the corresponding sliders 12. Then, the telescopic rod 17 drives the base plate 30 and the telescopic positioning components installed on it to move upward by a distance Rr. Next, the output end of the telescopic rod 35 extends out by a distance of 2*(Rr). Then, the drive screw 13 rotates to drive multiple sliders 12 to move. With the action of the clamp set between the slider 12 and the slide rail 35, the position of multiple telescopic positioning components is adjusted so that the output end of the telescopic rod 35 on the current telescopic rod 2 14 is aligned with the stop on the next telescopic rod 2 14. Plate 16 abuts until the midpoint line of the distance between the two support rollers 28 installed on the multiple telescopic positioning components is collinear with the central axis of the multiple aluminum profiles 5 to be cut. Then, multiple telescopic rods 14 push the support rollers 28 to one side of the cutting groove. Then, multiple aluminum profiles 5 are pushed in at the same time so that the aluminum profiles 5 cover the corresponding two support rollers 28. At this time, two telescopic rods 27 push the support rollers 28 to unfold until the support rollers 28 abut against the inner wall of the aluminum profiles 5. Continue to push the aluminum profiles 5 to the length to be cut. The cutting blade 4 is used to complete the cutting of the aluminum profiles 5.

[0042] The above technical solution has the following beneficial effects: 1. When the distance between the two support rollers 28 is the smallest, the two support rollers 28 are first pushed to a position close to one side of the cutting groove by the telescopic rod 2 14. Then, the aluminum profile 5 is pushed in so that the aluminum profile 5 covers the two support rollers 28. Then, the two support rollers 28 are unfolded to abut against the inner wall of the aluminum profile 5. At this time, the telescopic positioning component can play a positioning and guiding role, so that the aluminum profile 5 will not have a positional deviation problem during the pushing and cutting process. Second, the telescopic positioning component can play an auxiliary fixing role. When the support roller 28 is unfolded and abuts against the inner wall of the aluminum profile 5, the position of the aluminum profile 5 can be constrained and fixed even without the action of the vertical clamping component and the horizontal clamping component. Alternatively, the vertical clamping component and the horizontal clamping component can generate a small clamping force, which can keep the aluminum profile 5 stable during cutting, thereby reducing the possibility of the aluminum profile 5 being squeezed and deformed or cut due to the clamping force. Third, when the two support rollers 28 are pushed to the position where they fit against one side of the cutting groove and form a rotation support, they support the aluminum profile 5 at the edge of the cut, reducing the possibility of cutting deformation at the cut of the aluminum profile 5 or weakening the degree of cutting deformation. Fourth, since the support rollers 28 form a support on one side of the cut, when the edge of the aluminum profile 5 on the other side of the cut deforms, during the next cut, when the two support rollers 28 at the smallest spacing position are pushed to the support rollers 28 at the edge of the aluminum profile 5, the support rollers 28 can gradually extend and rotate until the maximum extension distance of the support rollers 28 is the same as the inner diameter of the aluminum profile 5. At this time, the cut edge of the deformed aluminum profile 5 will gradually return to its original shape under the action of rotating the support rollers 28, ensuring the cutting quality. 5. When the support roller 28 unfolds and abuts against the inner wall of the aluminum profile 5, and after the aluminum profile 5 is cut, the friction between the support roller 28 and the aluminum profile 5, as well as the radial force generated when the support roller 28 unfolds, allows the support roller 28 to maintain a connection with the aluminum profile 5. Then, the telescopic positioning component, the base platform 9, and the cut aluminum profile 5 fitted on the support roller 28 rotate along the base plate 30 to a position where they are disengaged from the cutting groove. This facilitates the processing of the cut profile and avoids the problem of the cut profile accumulating in the cutting groove, which would require additional manual processing.

[0043] Furthermore, the output shaft of the drive device 25 extends to one end of the grid frame 24 and is fixedly connected to a blade 29. When the drive device 25 drives the support roller 28 to rotate, it will drive the blade 29 to rotate together, forming an airflow. The debris generated by the cutting blade 4 cutting the aluminum profile 5 will be blown away and will not enter the interior of the cut aluminum profile 5, ensuring the cleanliness of the inner wall of the subsequently cut aluminum profile 5.

[0044] Furthermore, there are two base platforms 9, which are fixedly connected by a connecting block 10. The connecting block 10 is rotatably connected to the base plate 30 via a rotating shaft. The bottom of the base plate 30 is fixedly connected to the base plate 30, and the output shaft of the base plate 30 is connected to the rotating shaft. The base plate 30 is existing technology and includes equipment such as motors and related accessories. The base plate 30 drives the connecting block 10 to rotate the two base platforms 9. Multiple telescopic positioning components movably connected on the two base platforms 9 are symmetrically arranged about the center of the rotating shaft.

[0045] After the multiple telescopic positioning components connected to one of the base platforms 9 perform positioning, guiding, auxiliary fixing, and cutting of the aluminum profile 5 to be cut, the multiple telescopic positioning components connected to the other base platform 9 are in an idle state. Then, the base plate 30 drives the locking groove 20 to rotate the two base platforms 9. At this time, the base platform 9 with the telescopic positioning components connected to the aluminum profile 5 to be cut moves to the other side to facilitate the stacking of the cut aluminum profile 5. Meanwhile, the base platform 9 with the multiple empty telescopic positioning components moves to a position aligned with the aluminum profile 5 to be cut. At this time, the telescopic positioning components on this side can continue to perform positioning, guiding, auxiliary fixing, and cutting support on the aluminum profile 5 to be cut.

[0046] Furthermore, a side baffle 34 is fixedly connected to one side of the base platform 9, and the length of the side baffle 34 is the same as the length of the grid frame 24 and the support roller 28.

[0047] A storage cart 31 is provided on the side of the extension base 6 away from the operating table 1. The storage cart 31 is existing technology. The storage cart 31 is equipped with casters with self-locking function. The upper surface of the storage cart 31 is lower than the lower surface of the base plate 30.

[0048] After a cut is completed, the drive unit 8 drives the connecting block 10 and the two base platforms 9 to rotate 180 degrees, so that the base platform 9 connected to the telescopic positioning assembly of the cut aluminum profile 5 moves to the other side and is aligned with the storage cart 31. At this time, the telescopic rod 14 and the telescopic rod 27 drive the support roller 28 to gradually retract, and one edge of the cut aluminum profile 5 abuts against the side baffle 34. Therefore, when the telescopic rod 14 drives the support roller 28 to gradually retract, the cut aluminum profile 5 is blocked by the side baffle 34 and gravity, causing the cut aluminum profile 5 to detach from the support roller 28 and fall into the storage cart 31, avoiding the problem of manual stacking. At the same time, the base platform 9 connected to multiple empty telescopic positioning assemblies moves to the position aligned with the aluminum profile 5 to be cut. At this time, the telescopic positioning assembly on this side can continue to perform positioning, guiding, auxiliary fixing and cutting support on the aluminum profile 5 to be cut, thereby improving the cutting efficiency.

[0049] Since the grid frame 24, support rollers 28 and other structures have a certain length, when the required cutting length of the aluminum profile 5 is shorter than the width of the output end connection structure of the telescopic rod 14, the shorter width of the cut aluminum profile 5 can also fall into the storage cart 31 through the action of the side baffle 34.

[0050] Furthermore, when multiple aluminum profiles 5 need to be cut simultaneously in multiple layers, multiple vertical mounting plates 32 are fixedly connected to the outer circumference of each telescopic rod 2 14. Each vertical mounting plate 32 is fixedly connected to a telescopic rod 5 33. The telescopic rod 5 33 is existing technology and includes pneumatic, electric and other drive methods. The output end of the telescopic rod 5 33 connected to the bottom telescopic rod 2 14 is movably connected to the vertical mounting plate 32 connected to the outer circumference of the top telescopic rod 2 14. The telescopic rod 5 33 connected to the bottom telescopic rod 2 14 pushes the top telescopic rod 2 14 to rise, so as to adapt to the cutting of aluminum profiles 5 of different diameters.

[0051] First, multiple vertical mounting plates 32 are connected to the outer circumference of the telescopic rod 2 14. Each vertical mounting plate 32 can be detachably connected to a telescopic rod 5 33. The output end of the telescopic rod 5 33 is detachably and movably connected to the vertical mounting plate 32 corresponding to the top telescopic rod 2 14. This allows multiple telescopic positioning components to be connected to the base platform 9, forming a single layer of multiple aluminum profiles 5 for positioning, guiding, cutting support, etc. Through the action of the vertical mounting plates 32 and the telescopic rod 5 33, the number of telescopic positioning components can be increased vertically, so as to realize the simultaneous multi-layer cutting of multiple aluminum profiles 5, thereby improving cutting efficiency, ensuring cutting quality, and avoiding the problem of cutting, squeezing and deformation.

[0052] Currently, the common operation for simultaneous multi-layer cutting of multiple aluminum profiles 5 is as follows: Multiple aluminum profiles 5 are neatly stacked. Typically, the upper aluminum profile 5 is placed in the gap formed by the two lower aluminum profiles 5. The neatly stacked aluminum profiles 5 are then constrained externally with packaging bags or tape, and then the multiple aluminum profiles 5 are pushed in for overall cutting. This method has the following drawbacks: 1. The stacking method with multiple layers at intervals results in multiple stacked aluminum profiles 5 forming a pyramid shape. The amount of aluminum profiles 5 in a single layer decreases as you move up, affecting cutting efficiency. In this technical solution, multiple layers of aluminum profiles 5 can be stacked neatly, and the number of aluminum profiles 5 in different layers is the same, which can effectively ensure cutting efficiency. Second, the initial constraint and fixation of multi-layer stacked aluminum profiles 5 using packaging bags, tape, etc., has a poor constraint effect, and the constraint treatment of covering and wrapping is quite troublesome. In this technical solution, two support rollers 28 that are close to or far apart from each other are used to guide, position, assist in fixing, and support the cutting of aluminum profiles 5, which can effectively ensure the constraint and fixation effect of multi-layer stacked aluminum profiles 5, thereby ensuring cutting stability. Third, during multi-layer stacking and cutting, the multiple aluminum profiles 5 stacked together exert multi-directional mutual compressive forces on each other, making the stress on the aluminum profiles 5 more complex and prone to cutting and extrusion deformation. In this technical solution, the aluminum profiles 5 are subjected to the action of two support rollers 28 that are close to or far apart from each other. The two support rollers 28 unfold during cutting to form support from the inside, and the contact area between two adjacent aluminum profiles 5 is reduced, which reduces the possible interaction force and reduces the possibility of cutting and extrusion deformation.
