Description

Technical Field

[0001] This utility model belongs to the field of aluminum disc production technology, and specifically relates to an aluminum disc stamping strip correction device. Background Technology

[0002] In the aluminum product processing industry, aluminum discs are an important basic component, widely used in kitchenware, electronic components, automotive parts, and other industries. Their production process typically employs a stamping process to continuously process aluminum strips, using stamping dies to cut discs of the required dimensions from the strip. This continuous stamping method is characterized by high production efficiency and low cost, and therefore is widely used in industrial production. In actual production, aluminum strip is prone to deviation during conveying and stamping. On the one hand, the strip itself may have defects such as curling, wrinkles, or uneven thickness, which can easily cause lateral displacement due to uneven force when conveyed by the drive rollers. On the other hand, installation errors of the conveying mechanism, differences in the speed of the drive rollers, and the impact force generated during the stamping process can also cause the strip to deviate from the preset stamping position. Some production lines have begun to use cylinders to push guide plates to laterally limit the strip, but these devices are mostly fixed structures and cannot be flexibly adjusted according to the width and displacement of the strip. Moreover, when the strip is conveyed at high speed, rigid contact can easily cause damage to the edges of the strip. Utility Model Content

A movable support is connected to one side of the upper part of the base plate. A frame is slidably connected to the upper part of the movable support. Both sides of the upper end of the frame are inclined. Drive rollers are rotatably connected to the lower parts of both sides of the inner wall of the frame. Electric telescopic rods are connected to both sides of the upper end of the inner wall of the frame. The frame is connected to an inverted U-shaped plate at one end. Fixed rollers are rotatably connected to both sides of the inner wall of the inverted U-shaped plate. A material strip is placed on the upper end of multiple drive rollers. Multiple fixed rollers press against one side of the upper end of the material strip. One side of the material strip is located above the stamping table. A material strip stabilizing mechanism is connected to the middle of the upper end of the frame. The material strip stabilizing mechanism includes a housing. The lower end of the housing is connected to the upper end of the frame. A pressing mechanism is slidably connected to one side of the housing. The pressing mechanism includes a sliding rod. The shape of the sliding rod is adapted to the shape of one side of the upper end of the frame. A support roller is rotatably connected to one side of the lower end of the sliding rod. The lower end of the support roller contacts one side of the upper end of the frame. In the above technical solution, a drive motor is further connected to the middle of one side of the housing, and a bidirectional lead screw is connected to the output end of the drive motor. One end of the bidirectional lead screw extends through the housing and connects to one side of the inner wall of the housing.

[0005] In the above technical solution, further, both sides of the outer wall of the bidirectional lead screw are slidably connected to sliders, and the two sliders slide on both sides of the inner wall of the housing, with one end of the two sliders extending through to one side of the housing. In the above technical solution, the lower end of the slide bar is further connected to a first connecting block, the upper part of one side of the first connecting block is connected to a slide plate, the lower part of one side of the slide plate is provided with a rotating groove, the upper end of the inner wall of the multiple rotating grooves is rotatably connected to a stabilizing roller, and one side of the multiple stabilizing rollers is in contact with one side of the material belt. In the above technical solution, the end of the slide away from the first connecting block is connected to a second connecting block, a slip ring is connected to the lower part of one side of the second connecting block, a roller is connected to the inner wall of the slip ring, and one end of the roller is connected to the lower part of one side of the support box. In the above technical solution, the inner wall of the slip ring is further provided with circumferentially embedded balls, and the balls respectively contact the outer wall of the roller. The inner wall of the slip ring is provided with rolling grooves corresponding to the balls, and the balls are respectively located inside the rolling grooves.

[0006] In the above technical solution, further, micro motors are uniformly connected to the upper part of one side of the slide plate, the output ends of the two micro motors extend through to one side of the slide plate, the output ends of the two micro motors are connected to rotating rods, and pressure rollers are rotatably connected to the lower part of one side of the two rotating rods, and the lower ends of the two pressure rollers respectively contact the upper sides of the material belt.

One end of each of the two guide rods is slidably connected inside the two guide grooves.

[0008] Compared with the prior art, the present invention has the following beneficial effects: Through the coordinated action of the material belt stabilization mechanism and the pressing mechanism, the stabilizing rollers form lateral constraints on the material belt from both sides, and the pressing rollers press the material belt from the top. Together with the lower support of the drive roller, a multi-dimensional constraint system is formed, which can effectively prevent the material belt from shifting left and right, swaying up and down, or wrinkling locally due to its own softness or external force interference during the conveying process, ensuring that the material belt is always conveyed to the stamping area in a flat state.

[0009] The drive motor drives the bidirectional lead screw to rotate, which can drive the clamping mechanisms on both sides to adjust the spacing synchronously. This allows the stabilizing roller and pressure roller to be flexibly adapted to material strips of different widths. It can meet the stamping requirements of aluminum discs of various specifications without changing the equipment, thus improving the versatility and applicability of the device. The surfaces of the fixed roller and pressure roller are covered with an elastic rubber layer, which can avoid scratches or indentations caused by rigid contact with the material belt; the design of rolling components such as support rollers and balls converts sliding friction into rolling friction, reducing the wear of the material belt caused by the movement of the mechanism and ensuring the surface quality of the material belt.

[0013] The system includes a base plate 1, a stamping table 2 connected to the upper middle part of the base plate 1, a support box 3 connected to one side of the base plate 1 corresponding to one side of the stamping table 2, a hydraulic cylinder 4 connected to the upper part of one side of the support box 3, a stamping block 5 connected to the lower end of the hydraulic cylinder 4, a movable support table 6 connected to one side of the upper end of the base plate 1, a frame 7 slidably connected to the upper end of the movable support table 6, both sides of the upper end of the frame 7 are inclined, drive rollers 8 are rotatably connected to the lower part of both sides of the inner wall of the frame 7, electric telescopic rods 9 are connected to the upper sides of both sides of the inner wall of the frame 7, an inverted U-shaped plate 10 is connected to the lower end of the two electric telescopic rods 9, fixed rollers 11 are rotatably connected to both sides of the inner wall of the inverted U-shaped plate 10, a material strip is placed on the upper end of multiple drive rollers 8, multiple fixed rollers 11 are pressed against one side of the upper end of the material strip, one side of the material strip is located above the stamping table 2, and a material strip stabilizing mechanism is connected to the upper middle part of the frame 7. The movable support platform 6 consists of a movable box, an electrically controlled slide rail, and a stabilizing block. The stabilizing block slides on the upper end of the electrically controlled slide rail, which can drive the frame 7 to move left and right. A connecting motor is connected to one side of the frame 7 at a location corresponding to multiple drive rollers 8. The output ends of the multiple connecting motors are connected to the multiple drive rollers 8 respectively. The inverted U-shaped plate 10 is used to connect multiple fixed rollers 11, which can drive the multiple fixed rollers 11 to move up and down. The surface of the fixed rollers 11 is covered with an elastic rubber layer to avoid damaging the material strip. The multiple fixed rollers 11 form a stable clamping force under the action of the electric telescopic rod 9. A drive motor 13 is connected to the middle of one side of the housing 12. A bidirectional lead screw 14 is connected to the output end of the drive motor 13. One end of the bidirectional lead screw 14 extends through the inside of the housing 12 and is connected to one side of the inner wall of the housing 12. Sliding blocks 15 are slidably connected to both sides of the outer wall of the bidirectional lead screw 14. The two sliders 15 slide on both sides of the inner wall of the housing 12 respectively. One end of the two sliders 15 extends through the housing 12 to one side. The two-way lead screw 14 has two sliders 15 on its outer walls that are slidably connected to each other. The sliders 15 are located in the matching guide grooves on both sides of the inner wall of the housing 12 to ensure smooth movement along a straight line. The material belt stabilizing mechanism includes a housing 12, the lower end of which is connected to the upper end of the frame 7. A pressing mechanism is slidably connected to one side of the housing 12. The pressing mechanism includes a slide rod 16, the shape of which matches the shape of one side of the upper end of the frame 7. A support roller 17 is rotatably connected to one side of the lower end of the slide rod 16, and the lower end of the support roller 17 contacts one side of the upper end of the frame 7. A first connecting block 18 is connected to the lower end of the slide rod 16. A sliding plate 19 is connected to the upper part of one side of the first connecting block 18. The lower surface of the sliding plate 19 is at the same level as the upper surface of the stamping table 2, facilitating the left and right movement of the material belt above the stamping table 2. Rotating grooves are provided on the lower part of one side of the sliding plate 19. Stabilizing rollers 20 are rotatably connected to the upper ends of the inner walls of multiple rotating grooves, with one side of each stabilizing roller 20 contacting one side of the material belt. A second connecting block 21 is connected to the end of the sliding plate 19 away from the first connecting block 18. A slip ring 23 is connected to the lower part of one side of the slide 19. A roller 22 is connected to the inner wall of the slip ring 23. One end of the roller 22 is connected to the lower part of one side of the support box 3. The inner wall of the slip ring 23 is circumferentially embedded with balls. Multiple balls contact the outer wall of the roller 22. Rolling grooves are opened on the inner wall of the slip ring 23 corresponding to multiple balls. Multiple balls are located inside multiple rolling grooves. Micro motors 24 are evenly connected to the upper part of one side of the slide 19. The output ends of two micro motors 24 extend through to one side of the slide 19. Rotating rods 25 are connected to the output ends of two micro motors 24. Pressure rollers 26 are rotatably connected to the lower part of one side of the two rotating rods 25. The lower ends of the two pressure rollers 26 contact the upper sides of the material belt. Guide rods are connected to one side of the two rotating rods 25. Guide grooves are opened on one side of the slide 19 corresponding to two guide rods. One end of the two guide rods is slidably connected inside the two guide grooves. The slide bar 16 has a high degree of fit with the upper end of the frame 7, and the slide bar 16 can move synchronously with the frame 7 without relative offset. The support roller 17 can rotate flexibly, reducing the frictional resistance when the slide bar 16 moves. The slide plate 19 can prevent wrinkles caused by height difference when the material strip moves above the stamping table 2. The stabilizing roller 20 is evenly distributed along the material strip conveying direction. The ball bearings cooperate with the rolling groove to convert the sliding friction between the slip ring 23 and the idler roller 22 into rolling friction, reducing wear and improving smooth movement. The surface of the pressure roller 26 is covered with an elastic rubber layer to avoid damaging the material strip and enhance friction. The guide rod cooperates with the guide groove to ensure the accurate pressing direction of the pressure roller 26 and avoid offset.

[0014] Working principle: When using the device, the operator first places the aluminum strip to be stamped flat on the top of multiple drive rollers 8, ensuring that the edge of the strip is parallel to the axis of the drive rollers 8 to avoid initial offset. At this time, the electronically controlled slide rail is activated, driving the stabilizing block and the frame 7 to make slight adjustments left and right until one side edge of the strip is aligned with the stamping center axis of the stamping table 2, and extends precisely above the stamping table 2 to complete the initial positioning. Then, the electric telescopic rod 9 is activated, which drives the lower end face of the inverted U-shaped plate 10 and multiple fixed rollers 11 to contact the upper side of the material belt. The clamping force of the fixed rollers 11 and the drive roller 8 is used to initially limit the swaying of the material belt in the vertical direction. At this time, the connecting motor is activated, and the drive roller 8 begins to rotate clockwise. Through surface friction, the material belt is pushed to move towards the side closer to the stamping table 2, entering the continuous conveying stage. When the conveyor belt begins to be conveyed, the conveyor belt stabilizing mechanism is activated simultaneously: the drive motor 13 drives the bidirectional lead screw 14 to rotate, causing the two sliders 15 to move horizontally towards or away from each other along the housing 12, thereby driving the clamping mechanisms on both sides to adjust the spacing synchronously until the stabilizing roller 20 contacts the edge of the conveyor belt, adapting to conveyor belts of different widths. During the adjustment of the clamping mechanism, the slide bar 16 is adapted to the inclined structure at the upper end of the frame 7, and the support roller 17 at its lower end slides along the wear-resistant guide rail at the upper end of the frame 7. At the same time, the slip ring 23 on one side of the second connecting block 21 rolls along the outer wall of the idler roller 22 through circumferentially evenly distributed balls to prevent the conveyor belt from being affected by the shaking of the mechanism. After the width is adjusted to the appropriate width, multiple stabilizing rollers 20 on one side of the slide plate 19 come into contact with the two sides of the conveyor belt, and limit the conveyor belt through the lateral constraint force generated by the rolling contact, preventing the conveyor belt from deviating to the left or right during conveying. In addition, the micro motor 24 drives the rotating rod 25 to rotate. When the rotating rod 25 rotates, the guide rod slides along the guide groove to ensure that the pressure roller 26 presses the material strip from both sides at a certain angle. When the material strip wrinkles due to uneven thickness or local soft areas, the lateral thrust of the stabilizing roller 20, the upper pressure of the pressure roller 26 and the lower support force of the drive roller 8 form a triangular force balance, which quickly smooths out the wrinkles. At the same time, the rolling cooperation between the idler roller 22 and the slip ring 23 can disperse the lateral tension of the material strip during conveying to the support box 3, preventing the material strip from shifting in the area away from the stamping table 2, and ensuring that the material strip is always conveyed to the top of the stamping table 2 in a flat state. When the material strip is conveyed to the stamping position, the connecting motor is immediately de-energized, causing the drive roller 8 to stop rotating quickly. The material strip stops precisely, and the hydraulic cylinder 4 drives the stamping block 5 to move down, completing the stamping of the aluminum disc above the stamping table 2. After stamping, the piston rod of the hydraulic cylinder 4 drives the stamping block 5 to reset. The material strip is moved to the left or right by the moving support table 6, which facilitates stamping of the material strip at multiple positions. After stamping, the material strip continues to move to one side by the drive roller 8. The stamped material strip continues to move under the push of the drive roller 8. When it passes the support roller 22, the outer wall of the support roller 22 contacts the lower end face of the material strip, and its axis remains parallel to the material strip conveying direction, forming effective support for the material strip.
