Description

Technical Field

[0001] This utility model relates to the field of aluminum film processing technology, and in particular to an aluminum film punching mechanism. Background Technology

[0002] In the production and processing of aluminum foil, punching is a crucial step. Traditional aluminum foil punching equipment has several shortcomings. For example, the separation effect of the aluminum foil during punching is not ideal, and adhesion is prone to occur, affecting subsequent processing and product quality. The positioning of the punching die is not precise enough, resulting in large dimensional deviations and a high scrap rate. Moreover, the fixation of the aluminum foil by traditional equipment is not stable enough during punching, which can easily cause displacement of the aluminum foil during punching, further reducing punching accuracy. In addition, traditional punching equipment has a low degree of automation, and its production efficiency is difficult to meet the requirements of large-scale production. Furthermore, the maintenance and debugging of the equipment are also relatively inconvenient. Therefore, a new type of aluminum foil punching mechanism is needed to solve these problems. Summary of the Invention

[0003] The purpose of this utility model is to provide an aluminum film punching mechanism that has the advantages of high punching precision, efficient aluminum film separation and collection, strong equipment adaptability, convenient maintenance, high degree of automation and high production efficiency, and can effectively solve the problems existing in traditional aluminum film punching equipment, so as to solve the above-mentioned technical problems.

[0004] To achieve the above technical solution, the technical solution of this utility model is as follows: An aluminum foil punching mechanism mainly consists of a frame, a first drive source, a lower punching die component, and an upper punching die component. The frame serves as the supporting framework for the entire mechanism, providing a stable mounting base for other components. The first drive source is vertically and flexibly mounted inside the frame, providing power for the punching action. The lower punching die component is located directly below the first drive source, serving not only to support the aluminum foil but also to collect the cut aluminum foil after punching. The upper punching die component is movably inserted into the frame and has high-speed airflow holes. During the punching process, the first drive source drives the upper punching die component to move closer to and squeeze towards the lower punching die component, while simultaneously, a high-speed airflow is instantaneously blown in to separate the aluminum foil, thereby achieving efficient and precise aluminum foil punching operation.

[0005] Furthermore, the first drive source is a servo electric cylinder, mounted inside the frame via a motor mounting plate. The servo electric cylinder boasts advantages such as high precision, high speed, and high stability, enabling precise control of the lifting and lowering motion of the upper punching die components. Sensors are installed at the beginning and end positions of the servo electric cylinder, allowing real-time monitoring of its stroke position and feedback of this information to the control system. This enables the control system to accurately control the servo electric cylinder's movements according to a preset program, ensuring the accuracy and repeatability of the punching process and effectively avoiding punching quality problems caused by errors in the drive source's motion.

[0006] Furthermore, the upper punching die assembly includes a punching die support that is slidably inserted into the inner side of the frame. The upper punching die support is detachably connected to the first drive source via an electric cylinder connector. This detachable connection facilitates the installation, disassembly, and maintenance of the upper punching die assembly. When it is necessary to replace the upper punching die assembly with different specifications to adapt to different punching requirements, the replacement operation can be carried out quickly, improving the flexibility and versatility of the equipment.

[0007] Furthermore, a punch fixing plate is fixedly installed below the upper punching die support. Guide positioning pins are detachably inserted at each of the four corners of the punch fixing plate. One end of each guide positioning pin abuts against the upper punching die support. These pins provide precise positioning during the punching process, ensuring accurate relative positioning of the upper and lower punching die components during die closing, thus guaranteeing punching precision. A punching cutter is inserted at the center of the punch fixing plate. This cutter is a key component for cutting the aluminum film, and its shape and size are designed according to the specific requirements of aluminum film punching. One end of the cutter connects to the air inlet channel on the upper punching die support, and the connection surface has good sealing. The cutter has a circumferential array of through-holes with high-speed airflow. During punching, high-speed airflow enters the cutter through the air inlet channel and exits through the high-speed airflow holes, using the impact force of the airflow to separate the cut aluminum film, effectively solving the problem of aluminum film adhesion. One end of the guide positioning pin is chamfered to facilitate smooth insertion into the corresponding hole of the lower punching die component during die closing, improving positioning efficiency.

[0008] Furthermore, a pressure plate is telescopically movable below the punch fixing plate, and an elastic element is provided between the pressure plate and the punch fixing plate. During the punching process, when the upper punching die component moves downward, the pressure plate first contacts the aluminum die and, under the action of the elastic element, presses the aluminum die firmly, preventing displacement of the aluminum die during punching and ensuring the accuracy and quality of punching. The pressure plate has recessed positioning holes, which can further assist in the positioning of the aluminum die, so that the aluminum die is in a more stable and accurate position before punching.

[0009] Furthermore, the lower die component includes a lower die support, on which a detachable profiler is mounted. The profiler's shape matches the shape of the aluminum film after punching, accurately supporting the aluminum film and ensuring the punch cutter cuts along a predetermined shape during punching, guaranteeing the accuracy of the punched shape. The lower die support has insertion holes adapted to guide positioning pins. During die closing, the guide positioning pins are inserted into these holes, achieving precise positioning and engagement between the upper and lower die components. The profiler is detachably equipped with a fixture positioning pin, which allows for precise positioning and installation of the profiler, ensuring accurate placement of the profiler on the lower die support.

[0010] Furthermore, a collection box can be pulled out directly below the cutting tool to collect the finished aluminum foil or waste material after punching, facilitating cleaning and organization. After punching is completed, the collection box can be pulled out to remove the aluminum foil for further processing, and then the collection box can be pushed back into place to prepare for the next punching and collection, improving the convenience and efficiency of the production process.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1) The guide positioning pins of the upper punching die component and the insertion holes of the lower punching die component, along with the precise connection between the upper punching die support and the first drive source, ensure the accurate relative position of the die during the punching process. During punching, the aluminum film can be cut under precise die positioning, effectively reducing punching dimensional deviations, improving product yield, and meeting the stringent requirements for aluminum film punching precision.

[0013] 2) The pressure plate of the upper die component in the punching process can firmly press the aluminum film before punching under the action of the elastic element, preventing the aluminum film from shifting during the punching process. This stable aluminum film fixing method further improves the punching accuracy, ensuring that each punching is carried out according to the predetermined shape and size, reducing punching errors caused by aluminum film movement, and providing a guarantee for the production of high-quality aluminum film products.

[0014] 3) The high-speed airflow holes on the punching blade of the upper die component instantly inject high-speed airflow during punching to separate the cut aluminum film, effectively solving the problem of aluminum film adhesion in traditional punching processes. This high-speed airflow separation method is fast and efficient, requiring no additional separation process, improving production efficiency, and also reducing the impact of aluminum film adhesion on subsequent processing and product quality.

[0015] 4) The collection box below the punching die component is pull-out, which facilitates the collection and cleaning of finished aluminum foil or waste materials after punching. During production, the collection box can be quickly pulled out for processing and then pushed back into place for continued use, greatly improving work efficiency, reducing downtime, and facilitating continuous production.

[0016] 5) The detachable connection between the upper punching die and the first drive source, as well as the detachable profile cutter in the lower punching die, allows for quick replacement of the die components to meet different aluminum foil punching requirements. This detachable design improves the equipment's adaptability to different specifications of aluminum foil products, reduces production costs, and facilitates the maintenance and repair of the die components. When a die component malfunctions or wears out, it can be replaced individually without replacing the entire equipment.

[0017] 6) Sensors are installed at both the beginning and end positions of the servo electric cylinder of the first drive source. These sensors can monitor the stroke position of the servo electric cylinder in real time and provide feedback to the control system. Sensor monitoring allows for timely detection of abnormalities during equipment operation, facilitating fault diagnosis and maintenance. Furthermore, the entire aluminum foil punching mechanism features a rational structural design with clear connections and layouts between components, facilitating daily inspection, cleaning, and maintenance, reducing maintenance costs, and extending the equipment's lifespan.

[0018] 7) This aluminum foil punching and cutting mechanism can achieve automated operation through a control system. From aluminum foil placement, punching, separation to collection, each step can be carried out automatically according to a preset program. Operators only need to perform simple equipment startup, parameter setting, and monitoring operations, greatly reducing labor intensity. The automated production process reduces the impact of human factors on punching quality, improves production efficiency, meets the needs of large-scale production, and provides strong support for enterprises to improve production efficiency.

[0019] In summary, this aluminum foil punching mechanism has advantages such as high punching accuracy, efficient aluminum foil separation and collection, strong equipment adaptability, convenient maintenance, high degree of automation, and high production efficiency. It can effectively solve the problems existing in traditional aluminum foil punching equipment and has broad application prospects in the aluminum foil processing industry.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please see the appendix Figures 1 to 3 As shown: An aluminum foil punching mechanism includes a frame 1, and the aluminum foil punching mechanism further includes:

[0027] The first drive source 2 is vertically and adjustable inside the frame 1 to provide power.

[0028] The punching die component 3 is positioned directly below the first drive source 2, serving to support the cutting of the aluminum film while simultaneously collecting it; and

[0029] The upper punching die component 4 is movably inserted into the frame 1. The upper punching die component 4 is provided with a high-speed airflow hole. The first driving source 2 can drive the upper punching die component 4 to move towards the lower punching die component 3 to squeeze and complete the cutting.

[0030] Wherein: the first drive source 2 drives the upper punching die component 4 to approach the lower punching die component 3 for cutting, and instantaneously blows in a high-speed airflow to separate them. The first drive source adopts a servo electric cylinder, which is mounted on the inner side of the frame through a motor mounting plate, and sensors are provided at the beginning and end positions of the servo electric cylinder. The servo electric cylinder has the characteristics of high precision, high speed and high stability, and can accurately control the lifting and lowering movement of the upper punching die component according to a preset program. The sensors monitor the stroke position of the servo electric cylinder in real time and feed back information to the control system to ensure that the movement trajectory of the upper punching die component is accurate and the coordination with the lower punching die component is just right, so as to achieve efficient and stable punching action and improve the overall punching performance and production efficiency of the equipment; the punching blade of the upper punching die component has a through high-speed airflow hole array along the axis, which is connected to the air inlet channel on the upper punching die support and is well sealed. When the first drive source drives the upper punching die component to approach the lower punching die component to cut the aluminum film, the instantaneously blown in high-speed airflow is ejected from the high-speed airflow hole of the punching blade. The powerful impact of the high-speed airflow can quickly separate the cut aluminum film, avoiding the problem of aluminum film sticking together in traditional punching methods. No additional separation process is required, which significantly improves the overall efficiency of punching, makes the production process smoother and more efficient, and reduces production time and costs.

[0031] Based on the above embodiments, the first driving source 2 is a servo electric cylinder; the servo electric cylinder is mounted on the inner side of the frame 1 through a motor mounting plate; sensors are provided at the beginning and end positions of the servo electric cylinder.

[0032] Based on the above embodiments, the upper punching die component 4 includes a upper punching die support 41 slidably inserted into the inner side of the frame 1; the upper punching die support 41 is detachably connected to the first drive source 2 via an electric cylinder connector; a punch fixing plate 42 is fixedly mounted below the upper punching die support 41; guide positioning pins 43 are detachably inserted at each of the four corners of the punch fixing plate 42; one end of each guide positioning pin 43 abuts against the upper punching die support 41; a punching blade 44 is inserted at the center of the punch fixing plate 42; a pressure plate 43 is retractably movable below the punch fixing plate 42; an elastic element 46 is provided between the pressure plate 43 and the punch fixing plate 42. The upper punching die component has detachable guide positioning pins at each of the four corners of the punch fixing plate, one end of which abuts against the upper punching die support, and the lower punching die support has insertion holes adapted to the guide positioning pins. During the punching process, the guide positioning pins are precisely inserted into the insertion holes, ensuring the accurate relative position of the upper and lower punching die components when the molds are closed. This effectively avoids dimensional deviations caused by die misalignment, significantly improving the precision of aluminum foil punching. This allows the punched aluminum foil products to meet high-quality production standards, reducing scrap rates and increasing production efficiency. A retractable pressure plate combined with an elastic element is located below the punch fixing plate. Before punching, the pressure plate, under the action of the elastic element, contacts and presses the aluminum foil. This design effectively prevents the aluminum foil from shifting or shaking due to force during punching, ensuring the aluminum foil remains stable at the moment of punching. This further improves the precision and quality stability of punching, ensuring that every punching operation yields aluminum foil products with precise dimensions and neat edges.

[0033] Based on the above embodiments, the upper die support 41 for punching is provided with an air inlet channel; one end of the punching blade 44 is connected to the air inlet channel and is sealed to the decryption surface; the punching blade 44 is provided with through high-speed airflow holes arranged in a circular array along the axis; one end of the guide positioning pin 43 is chamfered.

[0034] The pressure plate 45 is provided with recessed positioning holes.

[0035] Based on the above embodiments, the lower punching die component 3 includes a lower punching die support 31; a contour cutter 32 is detachably embedded on the lower punching die support 31; and a collection box 33 is retractable directly below the contour cutter 32. The upper punching die support is detachably connected to the first drive source via an electric cylinder connector. The contour cutter is detachably embedded on the lower punching die support, and a fixture positioning pin is detachably provided on the contour cutter. This detachable structural design allows the die components to be quickly replaced according to different aluminum film punching requirements. For example, when it is necessary to punch aluminum films of different shapes or sizes, the corresponding upper punching die component or contour cutter can be easily replaced without large-scale modification or adjustment of the entire equipment, greatly improving the adaptability of the equipment to diverse production tasks, reducing production costs, and also facilitating die maintenance and repair, extending the die's service life. A retractable collection box is provided directly below the contour cutter of the lower punching die component. During the punching process, the cut aluminum film finished product or waste material falls directly into the collection box. When the collection box is full or needs cleaning, it can be easily pulled out for cleaning or replacement, making the operation convenient and efficient. This design not only facilitates the collection and sorting of aluminum foil after punching, reducing the time and workload of manual cleaning, but also prevents aluminum foil from accumulating inside the equipment, affecting its normal operation, and helps maintain a clean production environment and stable equipment operation.

[0036] Based on the above embodiments, the punching die support 31 is provided with an insertion hole that matches the guide positioning pin 43;

[0037] The contour cutting tool 32 is detachably equipped with a fixture positioning pin.

[0038] In use, the aluminum foil punching mechanism is installed in a suitable working area, ensuring the frame is placed stably and that the frame's structural integrity and stability are checked for any looseness or deformation. The first drive source is installed, and the servo cylinder is securely mounted inside the frame via a motor mounting plate. The electrical wiring is connected, ensuring the sensor functions properly to accurately monitor and provide feedback on the servo cylinder's stroke position. The upper punching die assembly is installed, with the upper punching die bracket slidably inserted inside the frame and connected to the first drive source via the cylinder connector, ensuring a secure and easily detachable connection. Guide pins are inserted at the four corners of the punch fixing plate, with one end abutting against the upper punching die bracket. The punching cutter is installed in the center of the punch fixing plate, ensuring a tight and well-sealed connection between the punching cutter and the air inlet channel. A pressure plate and elastic element are installed below the punch fixing plate, allowing the pressure plate to move flexibly under the action of the elastic element, with accurate positioning holes on the pressure plate. Install the lower die component and detachably mount the profile cutter onto the lower die support. Use the fixture positioning pins for precise installation and positioning to ensure the profile cutter is accurately positioned. Set corresponding insertion holes on the lower die support to match the guide positioning pins. Install the collection box directly below the profile cutter to allow for smooth pulling. After assembly, begin the aluminum foil punching operation. Place the aluminum foil to be punched onto the profile cutter of the lower die component. Use the shape of the profile cutter and the positioning holes on the pressure plate to initially position the aluminum foil, ensuring it is in the correct punching position. Activate the first drive source (servo cylinder), which begins to descend, driving the upper die component downwards. During descent, the pressure plate first contacts the aluminum foil and, under the action of the elastic element, presses the foil firmly to prevent displacement during punching. As the upper die component continues to descend, the guide positioning pins insert into the insertion holes of the lower die component, achieving precise positioning and engagement between the upper and lower dies to ensure punching accuracy. When the upper and lower die components close, the cutting blade cuts the aluminum foil. Simultaneously, a high-speed airflow is instantaneously forced into the cutting blade through the air inlet. The airflow exits through high-speed airflow holes on the cutting blade, using its impact force to separate the cut aluminum foil and prevent it from sticking together. After cutting, the first drive source (servo cylinder) rises, returning the upper die component to its initial position. At this point, the collection box under the lower die component can be removed to clean the finished aluminum foil or waste material. The collection box is then pushed back into its original position, ready for the next cutting operation. In summary, this aluminum foil cutting mechanism, through its unique structural design, exhibits significant advantages in cutting accuracy, efficiency, equipment adaptability, and maintainability. It effectively solves many problems existing in traditional aluminum foil cutting equipment, meeting the modern aluminum foil processing industry's demand for efficient, high-precision, and multi-functional cutting equipment, and has broad application prospects and high market value.
