Description

Technical Field

[0001] This utility model belongs to the field of aluminum disc stamping technology, and specifically relates to a multifunctional aluminum disc stamping die. Background Technology

[0002] Aluminum discs, as an important type of aluminum product, are widely used in many fields such as electronics, home appliances, and automotive parts. Their production and processing rely on efficient and precise stamping dies. Currently, aluminum disc stamping dies typically consist of upper and lower die bases, stamping cutting edges, guiding mechanisms, and drive devices. The drive device drives the upper die downwards, allowing the stamping cutting edges to cooperate with the lower die to complete the stamping and forming of the aluminum sheet. As the market's requirements for the precision, efficiency, and quality of aluminum discs continue to increase, the limitations of traditional stamping dies in structural design are gradually becoming apparent, making it difficult to meet the requirements of thin aluminum discs.

[0003] During the stamping process of thin aluminum discs, the continuous friction between the stamping ring and the aluminum sheet generates a large amount of heat. Traditional molds lack a targeted heat dissipation structure, and the heat easily accumulates at the cutting edge of the stamping ring, causing the stamping ring temperature to rise. This not only reduces its service life but also causes the edges of the aluminum disc to soften due to heat and stick to the stamping ring, resulting in surface damage or deformation of the product and affecting processing quality. Furthermore, the thin aluminum discs have poor rigidity. If the fixing force on its edges is insufficient or the force is uneven during stamping, edge collapse, wrinkles, and other phenomena are very likely to occur. In severe cases, this can even lead to product scrap, increasing production costs and reducing production efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multifunctional aluminum disc stamping die.

[0005] To achieve the above objectives, this utility model provides a multifunctional aluminum disc stamping die, including a base. Support columns are connected to both sides of the upper end of the base. A top plate is connected to the upper end of each support column. A hydraulic cylinder is connected to the middle of the upper end of the top plate. The lower end of the hydraulic cylinder extends through to the lower end of the top plate. A lower pressure plate is connected to the lower end of the hydraulic cylinder. An installation mechanism is connected to the lower end of the lower pressure plate. The installation mechanism can fix the stamping ring. The installation mechanism includes a connecting cylinder with an inverted concave cross-section. An installation plate is connected to the middle of the lower end of the connecting cylinder. The stamping ring is connected to the middle of the lower end of the installation plate. The lower end of the stamping ring is connected to the installation plate by multiple installation bolts. A clamping mechanism is circumferentially connected to the outer wall of the connecting cylinder. In the above technical solution, a support ring is connected to the middle of the upper end of the base, and a discharge port is opened at the upper end of the base corresponding to the support ring.

[0006] In the above technical solution, the lower end of the connecting cylinder and the lower end of the mounting plate are both circumferentially connected to a first air outlet. The first air outlet is inclined in shape, and gas can be cooled on the inner wall of the stamping ring through multiple first air outlets. The lower end of the connecting cylinder is also circumferentially connected to a second air outlet. The second air outlet is inclined in shape, and gas can be cooled on the lower part of the outer wall of the stamping ring through multiple second air outlets. In the above technical solution, the upper end of the connecting cylinder is connected to an air inlet pipe, the upper end of the air inlet pipe passes through the lower pressure plate and the top plate in sequence and extends to the upper end of the top plate, and the middle part of the outer wall of the air inlet pipe is in the shape of a flexible tube. In the above technical solution, a drive motor is further connected to the lower middle part of the inner wall of the connecting cylinder, and a rotating plate is circumferentially connected to the outer wall of the output end of the drive motor. There are four sets of rotating plates, and a blocking plate is connected to one end of each of the rotating plates. The blocking plate is arranged in a Z-shaped structure and can block the first air outlet and the second air outlet. In the above technical solution, the clamping mechanism further includes a connecting rod, and the number of the connecting rods is four sets. A groove is opened on one side of the connecting rod. Buffer springs are evenly connected to the upper end of the inner wall of the groove. Buffer blocks are connected to the lower ends of the multiple buffer springs. The buffer blocks are convex in shape and the shape of the buffer blocks is adapted to the shape of the groove.

[0007] In the above technical solution, the number of buffer blocks is four sets, and the outer walls of multiple buffer blocks are connected to connecting rings. The lower ends of the connecting rings are circumferentially connected to support rods, and the lower ends of multiple support rods are connected to clamping rings. The inner diameter of the clamping rings is adapted to the inner diameter of the support rings.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The clamping mechanism, through the cooperation of the buffer spring and the buffer block, can apply a uniform and buffered pre-pressure to the edge of the aluminum sheet. Together with the support ring, it forms a stable clamp, effectively preventing the workpiece edge from collapsing or shifting during stamping, ensuring stamping accuracy. At the same time, the lower end face of the clamping ring is flat and smooth, which can prevent scratches on the surface of the aluminum sheet. The buffering effect of the buffer spring can reduce the rigid impact during the stamping process, protecting the workpiece from damage and reducing the wear of equipment parts.

[0009] The inclined design of the first and second air outlets allows for precise cooling of the inner and outer walls of the stamping ring. The Z-shaped blocking plate quickly blocks the air outlets during stamping, preventing continuous airflow from impacting the aluminum sheet and causing deformation. Ventilation is immediately opened after stamping. The Z-shaped blocking plate, in conjunction with the drive motor, can quickly block the air outlets during stamping to prevent airflow interference, and immediately open ventilation after stamping, achieving precise control of heat dissipation timing. This reduces the problem of aluminum disc adhesion caused by high temperatures and extends the service life of the stamping ring. Attached Figure Description

[0012] like Figures 1-6 The image shows a multifunctional aluminum disc stamping die.

[0013] The system includes a base 1, with support columns 2 connected to both sides of the upper end of the base 1. A top plate 3 is connected to the upper end of the support columns 2. A hydraulic cylinder 6 is connected to the middle of the upper end of the top plate 3. The lower end of the hydraulic cylinder 6 extends through to the lower end of the top plate 3. A lower pressure plate 7 is connected to the lower end of the hydraulic cylinder 6. An installation mechanism is connected to the lower end of the lower pressure plate 7. The installation mechanism can fix the stamping ring 10. The installation mechanism includes a connecting cylinder 8. The cross-section of the connecting cylinder 8 is set with an inverted concave structure. An installation plate 9 is connected to the middle of the lower end of the connecting cylinder 8. The stamping ring 10 is connected to the middle of the lower end of the installation plate 9. The lower end of the stamping ring 10 is connected to the installation plate 9 by multiple installation bolts 11. A clamping mechanism is circumferentially connected to the outer wall of the connecting cylinder 8. A support ring 4 is connected to the middle of the upper end of the base 1. A discharge port 5 is opened at the upper end of the base 1 corresponding to the support ring 4. The support column 2 is connected to the base 1 and the top plate 3 by bolt fastening. The interior of the connecting cylinder 8 forms an accommodating space to facilitate the accommodation and installation of other components. The mounting plate 9 has a flat surface and is fixed to the lower end of the connecting cylinder 8 by welding. The mounting bolt 11 facilitates the quick replacement of the stamping ring 10. Multiple clamping mechanisms are evenly distributed along the circumference of the outer wall of the connecting cylinder 8 to ensure that a uniform pre-pressure is applied to the edge of the workpiece. The top surface of the support ring 4 is parallel to the lower end surface of the stamping ring 10 and is used to support the workpiece to be stamped. The size of the discharge port 5 is adapted to the workpiece to be stamped, so that the stamped workpiece can fall smoothly and be collected.

[0014] Both the lower ends of the connecting cylinder 8 and the lower ends of the mounting plate 9 are circumferentially connected to first air outlets 12. The first air outlets 12 are inclined, allowing gas to cool the inner wall of the stamping ring 10 through multiple first air outlets 12. The lower ends of the connecting cylinder 8 are also circumferentially connected to second air outlets 13. The second air outlets 13 are inclined, allowing gas to cool the lower part of the outer wall of the stamping ring 10 through multiple second air outlets 13. An air inlet pipe 14 is connected to one side of the upper end of the connecting cylinder 8. The upper end of the air inlet pipe 14 passes through the lower pressure plate 7 and the top plate 3 in sequence and extends to the upper end of the top plate 3. The middle part of the outer wall of the air inlet pipe 14 is in the shape of a flexible tube. The middle part of the lower end of the inner wall of the connecting cylinder 8 is connected to the drive motor 15. The outer wall of the output end of the drive motor 15 is circumferentially connected to the rotating plate 16. There are four sets of rotating plates 16. One end of each rotating plate 16 is connected to a blocking plate 17. The blocking plate 17 is set in a Z-shaped structure. The blocking plate 17 can block the first air outlet 12 and the second air outlet 13. The first air outlet 12 is designed with an inclined direction to precisely align with the key area of ​​the inner wall of the stamping ring 10. The inclined angle of the second air outlet 13 can directly guide the gas to the outer wall of the stamping ring 10 near the cutting edge. The air inlet pipe 14 is used to connect to an external air source device. The middle part of the air inlet pipe 14 is flexible to adapt to the positional changes when the lower pressure plate 7 moves up and down, ensuring the continuity of gas delivery. The drive motor 15 provides power for the rotation of the blocking plate 17. The rotating plate 16 extends radially along the output end of the drive motor 15. The rotating plate 16 is used to transmit the power of the drive motor 15 to the blocking plate 17, so that the blocking plate 17 can rotate synchronously. The blocking plate 17 can effectively block the first air outlet 12 and the second air outlet 13 at the same time. In the blocked state, the plate surface of the blocking plate 17 can completely cover the first air outlet 12 and the second air outlet 13; in the open state, the plate surface and the air outlet are completely offset to ensure that the gas is ejected smoothly.

[0015] The clamping mechanism includes four sets of connecting rods 18. A groove 19 is provided on one side of the connecting rod 18. Buffer springs 20 are evenly connected to the upper end of the inner wall of the groove 19. Buffer blocks 21 are connected to the lower ends of the multiple buffer springs 20. The buffer blocks 21 are convex in shape and their shape matches the shape of the groove 19. There are four sets of buffer blocks 21. Connecting rings 22 are connected to the outer wall of the multiple buffer blocks 21. Support rods 23 are circumferentially connected to the lower ends of the connecting rings 22. Clamping rings 24 are connected to the lower ends of the multiple support rods 23. The inner diameter of the clamping rings 24 matches the inner diameter of the support rings 4. One end of the connecting rod 18 is fixedly connected to the outer wall of the connecting cylinder 8. The slide groove 19 is set along the length of the connecting rod 18 to guide the movement of the buffer block 21. The elastic force of the buffer spring 20 can provide a downward thrust for the buffer block 21 and play a buffering role during the pressing process to avoid rigid impact on the workpiece. The shape of the buffer block 21 and the slide groove 19 ensures the stability of the buffer block 21 when sliding in the slide groove 19 and prevents displacement. The connecting ring 22 connects multiple buffer blocks 21 into a whole so that each buffer block 21 can move synchronously. The support rod 23 is perpendicular to the lower end face of the connecting ring 22 and is used to support the pressing ring 24. The lower end face of the pressing ring 24 is flat and smooth to avoid scratching the surface of the workpiece. The inner diameter design of the pressing ring 24 can ensure that the edge area of ​​the workpiece to be processed can be accurately pressed during the stamping process and form a stable clamping with the support ring 4.

[0016] Working principle: When using the device, first select the appropriate stamping ring 10 according to the specifications of the thin aluminum disc to be stamped, and fix it to the lower end of the mounting plate 9 with the mounting bolts 11 to ensure a stable connection. Place the aluminum disc to be processed on the support ring 4 of the base 1, so that the area to be stamped is aligned directly below the stamping ring 10.

[0017] After the equipment is started, the hydraulic cylinder 6 pushes the lower pressure plate 7 to move downward, which drives the connecting cylinder 8, mounting plate 9 and stamping ring 10 to move downward simultaneously. At the same time, the clamping mechanism moves downward. When the clamping ring 24 contacts the edge of the aluminum sheet, the lower pressure plate 7 continues to move downward, and the buffer block 21 moves upward in the slide groove 19 and compresses the buffer spring 20, so that the clamping ring 24 presses tightly against the edge of the aluminum sheet to achieve pre-fixation.

[0018] Just as the stamping ring 10 is about to contact the aluminum sheet, the drive motor 15 starts, causing the rotating plate 16 to rotate 45 degrees. The rotating plate 16 then causes the blocking plate 17 to rotate 45 degrees synchronously. At this time, the solid part of the blocking plate 17 precisely covers the first air outlet 12 and the second air outlet 13, completing the blocking action. The air inlet pipe 14 stops air intake or maintains low pressure to prevent gas from being ejected and interfering with the stamping. Subsequently, the stamping ring 10 moves downward and cooperates with the support ring 4 to complete the punching. The aluminum disc falls into the collection device through the discharge port 5.

[0019] After stamping is completed, the hydraulic cylinder 6 drives the components to move upward, the drive motor 15 drives the rotating plate 16 to rotate in the opposite direction by 45 degrees, and the blocking plate 17 is reset synchronously. Its notch is completely aligned with the first air outlet 12 and the second air outlet 13 to release the blockage. The external air source supplies air to the connecting cylinder 8 through the air inlet pipe 14. The gas is sprayed out through the first air outlet 12 and the second air outlet 13 to blow air to cool the outer and inner walls of the stamping ring 10, and to cool the stamping ring 10 in all directions to avoid high temperature adhesion.

[0020] As the lower pressure plate 7 continues to move upward, the buffer spring 20 returns to its original position, causing the clamping ring 24 to disengage from the edge of the aluminum sheet, completing one stamping cycle. This can be repeated to achieve continuous operation.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
