Abstract
Description
Technical Field
[0001] This invention relates to the field of aluminum alloy strip production technology, specifically to an automatic shearing device for aluminum alloy strip. Background Technology
[0002] Aluminum alloy strip production is a technology-intensive and rigorous modern manufacturing process, widely used in aerospace, new energy vehicles, electronic communications, and packaging materials. The production process begins with smelting and casting. High-purity aluminum ingots are melted, and alloying elements such as magnesium and silicon are added for composition adjustment. Impurities are removed through online degassing and filtration, and advanced continuous or semi-continuous casting processes are used to form slabs. The slabs then enter a pretreatment stage, where homogenization annealing eliminates compositional segregation and improves processing plasticity. The core process is rolling. Hot rolling repeatedly rolls the thick slab to a certain thickness, breaking down the as-cast structure at high temperatures. After precision rolling in the cold rolling process, the strip thickness is further reduced to the micrometer level, while an automatic thickness control system ensures that dimensional tolerances meet strict standards. The rolled strip then undergoes intermediate or final annealing to regulate the material's mechanical properties and grain structure.
[0003] In the shearing process of aluminum alloy strip, failure to effectively flatten the strip directly affects the yield and subsequent processing efficiency. Without flattening constraints, the strip is highly susceptible to localized warping or flanging under shearing force. Due to stress release during shearing, unflattened strip edges will develop noticeable burrs, wavy edges, or even "ruffled" edges, severely impacting end-face flatness. For high-precision electronic or automotive strips, such edge defects can lead to gap deviations during subsequent welding or assembly. Summary of the Invention

[0013] This invention provides an automatic shearing device for aluminum alloy strip. It has the following advantages: 1. This automatic aluminum alloy strip shearing device, through the setting of the feeding mechanism, is the "feeding guide unit" of the device, responsible for guiding the aluminum strip coil smoothly into the device, reducing friction and sway, and ensuring smooth feeding.
[0014] Second, the automatic aluminum alloy strip shearing device, by setting a flow guiding mechanism, is the device's "anti-backward and tension control unit". Utilizing the characteristics of a one-way bearing, it allows the aluminum strip to be conveyed forward while preventing it from backing up due to springback during the cutting process, thus ensuring accurate cutting position.
[0015] Third, the automatic aluminum alloy strip shearing device has a leveling mechanism, which is the "leveling core" of the device. It is used to mechanically flatten the curled aluminum strip, eliminate curling stress, keep the strip flat before cutting, and improve the cutting quality.
[0016] IV. This automatic aluminum alloy strip shearing device, through the setting of a support plate and a stamping cutter, constitutes the final "fixed-length cutting unit".

[0017] V. This automatic aluminum alloy strip shearing device, through the setting of limiting posts and ball bearings, constitutes the rolling guide mechanism of the upper pressure roller assembly. A track bar, fixed to the top of the support rod, has an inner track consisting of a straight section and an arc-shaped section. When the leveling mechanism reciprocates under the drive of the reciprocating screw, the ball bearings slide within the track bar's track. In the straight section, the upper pressure roller maintains a horizontal height, applying constant pressure to the aluminum strip; upon entering the arc-shaped section, the track descends, causing the upper pressure roller to gradually press down, squeezing the curled aluminum strip. This design achieves automatic lifting and lowering of the leveling pressure roller during its reciprocating stroke, making the leveling action smoother and more efficient.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
[0021] like Figures 1-9As shown, the present invention provides a technical solution: an automatic aluminum alloy strip shearing device, including a base 1, a first aluminum frame 2 fixedly mounted on the upper surface of the base 1, a frame 3 fixedly mounted on the top of the first aluminum frame 2, and a second aluminum frame 8 fixedly mounted on the side of the upper surface of the base 1. By setting the base 1, the first aluminum frame 2, and the frame 3, a rigid frame is formed for the entire shearing device, providing a precise installation reference and a stable working platform for each functional component. The second aluminum frame 8 provides stable installation support for the stamping cutting machine 11. The feeding mechanism 6 is fixed on the upper surface of the base 1 on the side away from the second aluminum frame 8. By setting the feeding mechanism 6, it serves as the "feeding guide unit" of the device, responsible for guiding the aluminum strip coil smoothly into the device, reducing friction and sway, and ensuring smooth feeding. The flow guiding mechanism 7 is used to prevent the aluminum strip coil from retracting. A support rod 4 is fixed to the outer surface of the frame 3, and the flow guiding mechanism 7 is fixed to the top of the support rod 4. By setting the flow guiding mechanism 7, it serves as the "anti-backflow and tension control unit" of the device. Utilizing the characteristics of the one-way bearing 73, it allows the aluminum strip to be fed forward while preventing it from retracting due to springback during the cutting process, ensuring accurate cutting position. The leveling mechanism 9 is used to flatten the coiled aluminum strip. The leveling mechanism 9 is fixed in the inner cavity of the frame 3. By setting up the leveling mechanism 9, it is the "leveling core" of the device. It is used to mechanically flatten the coiled aluminum strip, eliminate the coiling stress, keep the strip flat before cutting, and improve the cutting quality. A support plate 10 is fixedly installed on the outer surface of frame 3 near the side of the second aluminum frame 8. This support plate 10 is used to support the bottom of the aluminum strip coil cutting area. A stamping cutter 11 is fixedly installed at the top of the second aluminum frame 8, with the cutting head of the stamping cutter 11 located directly above the support plate 10. By setting up the support plate 10 and the stamping cutter 11, the final "fixed-length cutting unit" is formed. The support plate 10 provides bottom support for the aluminum strip to prevent deformation during cutting; the stamping cutter 11 operates under control signals to precisely cut the flattened aluminum strip.
[0022] The feeding mechanism 6 includes a guide frame 61, which is fixed to the upper surface of the base 1. Track grooves are provided on both sides of the inner wall of the guide frame 61, and slots 62 are formed at the track grooves on the inner wall of the guide frame 61. The guide frame 61 serves as the supporting housing for the feeding mechanism 6, and the track grooves on both sides of its inner wall provide guidance for the installation and height adjustment of the roller 66. The slots 62 provide operating space for the installation and adjustment of the positioning ring 65, facilitating the insertion of the roller 66 into the inner cavity of the guide frame 61.
[0023] A first rolling bearing 63 is fixed to the inner wall of the guide frame 61, and a locking block 64 is fixed to the inner ring of the first rolling bearing 63. A positioning ring 65 is rotatably connected to the track groove inside the guide frame 61. The positioning ring 65 is adapted to the shape of the locking block 64, and a roller 66 is fixed to the side of the positioning ring 65 away from the locking block 64. The first rolling bearing 63 provides rotational support for the locking block 64. The locking block 64 and the positioning ring 65 form a quick installation and adjustment interface for the roller 66. The shape adaptation between the locking block 64 and the positioning ring 65 allows for quick assembly and disassembly of the roller 66, enabling rapid placement of the aluminum strip. The roller 66 is a conveying element that directly contacts the aluminum strip, guiding the strip smoothly into subsequent workstations.
[0024] Two flow guiding mechanisms 7 are provided, each positioned directly above one end of the frame 3. Each flow guiding mechanism 7 includes a fixed plate 71, which is fixed to the top of the support rod 4. A fixed ring 72 is fixed to the outer surface of the fixed plate 71, and a one-way bearing 73 is fixed to the inner wall of the fixed ring 72. A rotating rod 74 is fixed to the inner ring of the one-way bearing 73, and a first rubber cylinder 75 is fixed to the end of the rotating rod 74. Two first rubber cylinders 75 are provided, arranged in parallel, with the distance between them less than the thickness of the aluminum strip coil. The one-way bearing 73 allows the aluminum strip coil to pass between the two first rubber cylinders 75 without reverse movement. By providing two flow guiding mechanisms 7, located at the feed and discharge ends of the frame 3 respectively, a double anti-backflow protection is formed. The fixed plate 71, fixed ring 72, and one-way bearing 73 constitute a one-way rotational support for the first rubber cylinder 75. The one-way bearing 73 only allows the rotating rod 74 to rotate in one direction. By setting two parallel first rubber cylinders 75 with a spacing less than the thickness of the aluminum strip, the friction force drives the first rubber cylinders 75 to rotate when the aluminum strip passes between them. Due to the constraint of the one-way bearing 73, the first rubber cylinders 75 only allow the aluminum strip to move in the cutting direction. Once the aluminum strip tends to move backward, the one-way bearing 73 locks, preventing it from reversing. This purely mechanical anti-reversal design is responsive, highly reliable, and ensures the accuracy of the strip position during each cut.
[0025] The leveling mechanism 9 includes a stepper motor 91 and a limiting rod 93. The stepper motor 91 is fixed to the inner wall of the frame 3. A reciprocating lead screw 92 is mounted on the output end of the stepper motor 91 via a coupling. The end of the reciprocating lead screw 92 away from the output end of the stepper motor 91 is rotatably connected to the inner cavity of the frame 3. The limiting rod 93 is fixed to the inner wall of the frame 3. The stepper motor 91 serves as the power source for the leveling mechanism 9, providing precise and controllable rotational motion. The reciprocating lead screw 92 is a special type of lead screw with a bidirectional thread in its helical groove, enabling the lead screw nut 96 to automatically reverse direction during lead screw rotation, achieving reciprocating linear motion without complex reversing control. The limiting rod 93 provides linear guidance for the sliding ring 97, ensuring smooth and non-skewed movement of the leveling components.
[0026] The leveling mechanism 9 also includes a connecting frame 94. A lead screw nut 96 is fixed to one end of the connecting frame 94, threaded onto the outer surface of the reciprocating lead screw 92. A sliding ring 97 is fixed to the end of the connecting frame 94 away from the lead screw nut 96, slidably connected to the outer surface of the limiting rod 93. By setting the connecting frame 94, the lead screw nut 96 and the sliding ring 97 are connected as a whole, serving as a moving platform for the leveling actuator. The lead screw nut 96, in cooperation with the reciprocating lead screw 92, converts the rotational motion of the lead screw into the reciprocating linear motion of the connecting frame 94. The sliding ring 97, sliding on the limiting rod 93, provides precise linear guidance for the connecting frame 94, ensuring that the leveling component remains horizontal and does not twist during reciprocating motion.
[0027] A limiting tube 99 is fixedly installed at the bottom of the inner cavity of the connecting frame 94. A piston rod 98 is slidably connected to the inner cavity of the limiting tube 99. A spring 911 is fixedly installed at the bottom end of the piston rod 98, and the bottom end of the spring 911 is fixed at the bottom of the inner cavity of the limiting tube 99. A connecting frame 910 is fixedly installed at the top end of the piston rod 98. By setting the limiting tube 99 and the piston rod 98, an elastic lifting support structure is formed. The piston rod 98 can slide up and down within the limiting tube 99. By setting the spring 911, an upward elastic force is provided, so that the connecting frame 910 and the second rubber cylinder 913 above it are held in the upper limit position when there is no external force. When the leveling component presses down on the aluminum strip, the spring 911 is compressed, providing a certain floating pressure.
[0028] A second rolling bearing 912 is fixed to the inner wall of the connecting frame 910. A second rubber cylinder 913 is fixed to the inner ring of the second rolling bearing 912. A limiting ring 914 is fixed to the top of the connecting frame 910. A third rolling bearing 915 is fixed to the inner wall of the limiting ring 914. A rotating column 916 is fixed to the inner ring of the third rolling bearing 915. An anti-slip ring 917 is fixed to the outer surface of the rotating column 916, located directly above the second rubber cylinder 913. The second rolling bearing 912 and the second rubber cylinder 913 form a lower pressure roller, used to support and flatten the aluminum strip from below. The limiting ring 914, the third rolling bearing 915, the rotating column 916, and the anti-slip ring 917 form an upper pressure roller, located directly above the second rubber cylinder 913. The anti-slip ring 917 has a high coefficient of friction, increasing the friction with the aluminum strip. When the leveling mechanism 9 reciprocates, the upper and lower pressure rollers together clamp the aluminum strip, apply pressure to it, and roll and press it back and forth, effectively eliminating the curling deformation of the strip and making it flat.
[0029] Both ends of the rotating column 916 are fixed with limiting posts 918, and the outer surface of the limiting posts 918 is fitted with a ball 919. The top of the support rod 4 is fixed with a track bar 5, which is a curved grooved tubular component, including an arc-shaped section and a straight section. The straight section is symmetrically arranged at both ends of the arc-shaped section, and the inner cavities of the arc-shaped section and the straight section have a communicating track. The ball 919 is slidably connected to the track in the inner cavity of the track bar 5. By setting the limiting posts 918 and the ball 919, the rolling guide mechanism of the upper pressure roller assembly is formed. The track bar 5 is fixed to the top of the support rod 4, and its inner cavity track is composed of a straight section and an arc-shaped section. When the leveling mechanism 9 reciprocates under the drive of the reciprocating screw 92, the ball 919 slides in the track of the track bar 5. In the straight section, the upper pressure roller maintains a horizontal height, applying constant pressure to the aluminum strip. Upon entering the curved section, the track descends, causing the upper pressure roller to gradually press down, squeezing the curled aluminum strip. This design enables the leveling roller to automatically rise and fall during its reciprocating stroke, making the leveling process smoother and more efficient.
[0030] Working principle: The aluminum strip coil is drawn out from the unwinding frame, passes through the roller 66, and then the roller 66 is placed into the inner cavity of the guide frame 61, and the positioning ring 65 is matched with the locking block 64. The rolling support and guiding function of the roller 66 ensures that the strip enters the subsequent station smoothly and horizontally. The strip continues forward, passing sequentially through two guide mechanisms 7. Each guide mechanism 7 consists of two parallel first rubber cylinders 75, spaced slightly less than the strip thickness. As the strip moves forward, friction drives the first rubber cylinders 75 to rotate, and the one-way bearing 73 allows this rotation, ensuring smooth transport. If the strip tends to retract backward, the one-way bearing 73 immediately locks, preventing the first rubber cylinders 75 from rotating in the opposite direction, thus firmly clamping the strip and preventing it from rolling back. This purely mechanical anti-backward design ensures the accuracy and consistency of the strip's position during each cut; afterwards, the worker continues to pull the end of the aluminum strip, moving it and pulling it out to the required cutting length. After the strip enters the inner cavity of frame 3, the leveling mechanism 9 begins to work. Stepper motor 91 drives reciprocating screw 92 to rotate, causing screw nut 96 and the entire connecting frame 94 to reciprocate linearly along limit rod 93. The second rubber cylinder 913 on the connecting frame 94 and the upper anti-slip ring 917 together clamp the strip. With the reciprocating motion of the leveling mechanism 9, the upper and lower pressure rollers continuously roll and crush the strip, effectively eliminating the curling stress and wave deformation of the strip, making it flat. At the same time, the ball 919 slides in the track of track bar 5. In the straight section, the upper pressure roller maintains a horizontal height and crushes the aluminum strip with constant pressure; when entering the curved section, the track descends, causing the upper pressure roller to gradually press down and squeeze the curled aluminum strip. The leveled strip continues to be conveyed forward. When it reaches the preset length, the control system issues a command. The punch-type cutting machine 11 operates, and its cutting head punches downward, precisely cutting the strip with the support of the support plate 10. Due to the anti-backflow function of the guide mechanism 7, the strip will not retract backward due to the impact force during cutting, ensuring a neat cut and accurate length. The cut aluminum alloy strip is collected by workers. The device automatically enters the next work cycle: the leveling mechanism 9 continues to reciprocate, and the strip continues to be conveyed forward for the next fixed-length cut.
