Description

Technical Field

[0002] Curved aluminum panels are architectural decorative aluminum alloy sheets processed with special techniques to achieve curved shapes. Their core feature lies in breaking through traditional planar limitations, achieving a three-dimensional curved effect through unidirectional or multidirectional curvature design. Based on the complexity of the curvature, they can be divided into the following types: single-curved aluminum panels, double-curved aluminum panels, and spherical aluminum panels. Among these, stamping forming equipment is often required in the processing of double-curved aluminum panels.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5As shown, the aluminum single-panel stamping and forming mechanism of this utility model includes a base 1, a rotating disk 2 above the base 1, a support plate 3 fixedly connected to the side wall of the base 1, a driving assembly on the support plate 3, the driving assembly being able to drive the rotating disk 2 to rotate on the base 1, multiple sets of base plates 14 evenly fixedly connected to the rotating disk 2, a lower die base 15 fixedly connected to the base plate 14, the top of the lower die base 15 having a concave arc surface, an opening at the center of the rotating disk 2, a support column 8 fixedly connected to the center of the base 1, the top of the support column 8 penetrating the opening on the rotating disk 2 and fixedly connected to a mounting plate 9, and a pneumatic fitting fixedly installed on the top of the mounting plate 9. Cylinder 10, the output end of which passes through mounting plate 9 and is fixedly connected to upper die base 11. Upper die base 11 is located below mounting plate 9. A punch head 12 is fixedly connected to the bottom of upper die base 11. The bottom of punch head 12 has a convex arc surface. An annular cavity 17 is provided on the base 1. The annular cavity 17 is provided with a top support assembly. The top support assembly can slide upward to lift the workpiece when lower die base 15 rotates to the unloading position. During operation, the operator places the unprocessed workpiece on the empty lower die base 15. The drive assembly drives the rotating disk 2 to rotate, so that the lower die base 15 loaded with the unprocessed workpiece rotates to below upper die base 11. At this time, the drive assembly stops working. The rotating disk 2 stops rotating, and the cylinder 10 drives the upper die holder 11 to slide downwards, causing the stamping head 12 to stamp the workpiece on the lower die holder 15. Simultaneously, the operator can place a new, unprocessed workpiece on the new lower die holder 15. After the stamping head 12 completes the stamping, it rises and resets under the action of the cylinder 10. The drive assembly drives the rotating disk 2 to rotate again, repeating this process until the stamped workpiece rotates to the unloading station. At this point, the rotating disk 2 stops, the cylinder 10 drives the stamping head 12 to stamp a new workpiece, and the support assembly lifts the workpiece that has rotated to the unloading station on the lower die holder 15. The operator can unload the lifted workpiece while loading the new workpiece. The stamping process is complete. During the unloading process, the operator can use auxiliary tools to detect the curvature of the workpiece stamped on the lower die holder 15 when the rotating disk 2 is stationary. This achieves integrated operation of loading, stamping, detection and unloading, solving the problem that in most existing double-curved aluminum plate stamping equipment, after the curved surface of one workpiece is stamped, the operator places a new workpiece on the die holder to complete the stamping. This process is not only time-consuming and labor-intensive, but also cannot achieve continuous operation, resulting in low stamping efficiency. On the other hand, some curved surface stamping equipment that can operate continuously has difficulties in unloading the workpiece after it is stamped because the workpiece is tightly attached to the die holder, making it difficult to unload quickly.

[0024] The drive assembly includes a motor 4, a spur gear 6, and a gear ring 7. The motor 4 is fixedly mounted on the top of the support plate 3. The output end of the motor 4 is fixedly connected to a rotating shaft 5. The spur gear 6 is fixedly connected to the rotating shaft 5. The gear ring 7 is fixedly connected to the side wall of the rotating disk 2. The spur gear 6 meshes with the gear ring 7. The bottom end of the rotating disk 2 is fixedly connected to a rotating ring, which is rotatably connected to the base 1. During operation, after the material is loaded, the motor 4 drives the spur gear 6 on the rotating shaft to rotate, causing the gear ring 7 to drive the rotating disk 2 to rotate. When the lower die base 15 with the new workpiece rotates to below the stamping head 12, the motor 4 stops working, which facilitates the stamping, inspection, unloading, and loading operations, realizing automatic continuous stamping operation.

[0025] The top support assembly includes a top support rod 22, a spring 24, a guide block 25, and a top plate 26. The bottom of the base plate 14 is slidably connected to the top support rod 22. The top of the top support rod 22 extends into the inner cavity of the lower mold base 15 and is fixedly connected to the top plate 26. The top of the top plate 26 is uniformly provided with protrusions. The top of the lower mold base 15 is uniformly provided with multiple through slots 21. The through slots 21 communicate with the inner cavity of the lower mold base 15. The protrusions on the top plate 26 are adapted to the through slots 21. The bottom end of the top support rod 22 extends into the annular cavity 17. The bottom end of the top support rod 22 is slidably connected to a limit rod 23. The top of the limit rod 23 is fixedly connected to the bottom of the top support rod 22. A guide block 25 is fixedly connected to the side wall of the bottom end of the top support rod 22. A guide groove is provided on the inner side wall of the annular cavity 17. The guide block 25 is slidably connected to the guide groove.

[0026] The guide groove consists of an annular groove 18, a vertical groove 19, and an inclined groove 20. The annular groove 18 is incompletely annular. Four positioning rods 13 are fixedly connected to the bottom of the upper mold base 11, and four positioning sleeves 16 are fixedly connected to the top of the lower mold base 15. The positioning rods 13 and positioning sleeves 16 are adapted to each other. During operation, when loading, the top plate 26 retracts into the inner cavity of the lower mold base 15, and the spring 24 is in a compressed state. The guide block 25 is located in the annular groove 18. When the workpiece completes loading, stamping, and inspection, and rotates to the unloading position, the guide block 25 slides to the connection between the annular groove 18 and the vertical groove 19. At this time, the guide block 25 is spring-loaded by the spring 24. Under the action of force, the top support rod 22 slides upward, causing the top plate 26 to slide upward, which in turn causes the protrusion on the top plate 26 to slide out of the through groove 21 and lift the workpiece, making it convenient for the operator to directly remove the workpiece from the lower mold base 15. After that, the rotating disk 2 rotates again, and the guide block 25 slides along the inclined groove 20 until it enters the annular groove 18. During this process, the top support rod 22 drives the top plate 26 to retract into the inner cavity of the lower mold base 15 again, and the spring 24 is compressed again, which makes it convenient for the operator to load the material. Through the sliding cooperation between the positioning rod 13 and the positioning sleeve 16, the upper mold base 11 and the lower mold base 15 are auxiliary positioned when the cylinder 10 drives the punch head 12 to slide down.

[0027] A mounting bracket 27 is fixedly connected to the top of the support column 8. An arc-shaped seat 28 is fixedly connected to the side of the mounting bracket 27 away from the cylinder 10. An arc-shaped insert plate 32 is slidably connected to the arc-shaped insert plate 28. A rack plate 33 is fixedly connected to the side of the arc-shaped insert plate 32 away from the arc-shaped seat 28. A second motor 29 is fixedly mounted on the mounting bracket 27. A second rotating shaft 30 is fixedly connected to the output end of the second motor 29. A second spur gear 31 is fixedly connected to the second rotating shaft 30. The second spur gear 31 meshes with the rack plate 33.

[0028] The bottom end of the arc-shaped insert plate 32 is pointed and has an inclined surface. The thickness of the arc-shaped insert plate 32 gradually increases from the tip towards the rack plate 33. During operation, when the guide block 25 slides to the connection between the annular groove 18 and the vertical groove 19, the motor 29 starts. The motor 29 drives the spur gear 31 on the rotating shaft 30 to rotate, so that the rack plate 33 drives the arc-shaped insert plate 32 to rotate and slide along the arc-shaped seat 28 until the tip of the arc-shaped insert plate 32 contacts the workpiece on the lower mold base 15. After that, the tip of the arc-shaped insert plate 32 can be directly inserted between the workpiece and the lower mold base 15. As the arc-shaped insert plate 32 goes deeper, the thickness of the arc-shaped insert plate 32 continuously increases, which makes the gap between the workpiece and the lower mold base 15 continuously increase. With the help of the spring 24 and the top plate 26, it is convenient to quickly lift the workpiece.

[0029] Working principle: The operator places an unprocessed workpiece on an empty lower die holder 15. Motor 4 drives the spur gear 6 on the rotating shaft to rotate, causing the gear ring 7 to rotate the rotating disk 2. When the lower die holder 15 with the new workpiece rotates to below the stamping head 12, motor 4 stops working, the rotating disk 2 stops rotating, and cylinder 10 drives the upper die holder 11 to slide downwards, allowing the stamping head 12 to stamp the workpiece on the lower die holder 15. Simultaneously, the operator can place a new unprocessed workpiece on a new lower die holder 15. After the stamping head 12 completes the stamping, it rises and resets under the action of cylinder 10. Motor 4 drives the rotating disk 2 to rotate again. This process repeats until the stamped workpiece rotates to the unloading station. At this point, the rotating disk 2 stops, cylinder 10 drives the stamping head 12 to stamp a new workpiece, and the guide block 25 slides to the connection between the annular groove 18 and the vertical groove 19, and slides upwards under the elastic force of the compressed spring 24, causing the top support rod 22 to move accordingly. The top plate 26 slides upward, causing the protrusion on the top plate 26 to slide out of the through groove 21 and lift the workpiece. At the same time, the second motor 29 starts, driving the spur gear 31 on the rotating shaft 30 to rotate. This causes the rack plate 33 to rotate and slide the arc-shaped insert 32 along the arc-shaped seat 28 until the tip of the arc-shaped insert 32 contacts the workpiece on the lower die seat 15. After that, the tip of the arc-shaped insert 32 can be directly inserted between the workpiece and the lower die seat 15. As the arc-shaped insert 32 goes deeper, its thickness increases, causing the gap between the workpiece and the lower die seat 15 to increase. With the help of the spring 24 and the top plate 26, the workpiece can be quickly lifted. The operator can unload the lifted workpiece while loading. During the process from stamping to unloading, the operator can use auxiliary tools to detect the curvature of the stamped workpiece on the lower die seat 15 when the rotating plate 2 is stationary, realizing the integrated operation of loading, stamping, detection and unloading.
