Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy profile processing, in particular to a punching die for aluminum alloy profile processing. Background Art

[0002] Aluminum alloy profile processing refers to the cutting, forming, and processing of aluminum alloy materials to produce the desired profile products. A blanking die is a tool used for this purpose. It typically consists of an upper die and a lower die. Pressure is applied between the two dies to plastically deform or cut the metal material. Existing blanking dies typically use bolts to secure the lower die, making installation and removal cumbersome. Furthermore, the lower die cannot be flexibly fixed to different sizes, limiting the overall mold size. Therefore, we have introduced blanking dies for aluminum alloy profile processing. Utility Model Content

A limit slot 22 is provided at one end of the two movable frames 23 away from each other, and a guide rod 25 is interspersed and movably connected between the two movable frames 23. The guide rod 25 is located on the bidirectional threaded rod. The upper part of the threaded rod 24; a long slot 11 is opened at the upper end of the workbench 1, and a lower mold 12 is provided on the workbench 1; the telescopic end of the hydraulic cylinder 6 passes through the bracket 4, and the telescopic end of the bracket 4 is installed and connected to the upper mold 61, and the position of the upper mold 61 corresponds to the position of the lower mold 12; during transportation, the No. 1 motor 21 is fixedly connected to the right end of the workbench 1, the bidirectional threaded rod 24 is movably connected to the inner wall of the long slot 11 through a bearing, the guide rod 25 is fixedly connected to the inner wall of the long slot 11, and the two movable frames 23 do not contact the front and rear slot walls of the long slot 11. The four L-shaped clamps 26 are respectively located at the four corners of the lower mold 12.

[0027] Through the above scheme: start the No. 1 motor 21 to work, so that the No. 1 motor 21 drives the bidirectional threaded rod 24 to rotate, and the two movable frames 23 threadedly connected on the bidirectional threaded rod 24 move closer to each other under the cooperation of the guide rod 25, and the two L-shaped clamping parts 26 on the two movable frames 23 jointly clamp the lower mold 12, thereby improving the installation convenience.

[0028] In this embodiment, the protective device 7 includes a No. 2 motor 71 and a transparent protective plate 75. The output end of the No. 2 motor 71 is fixedly connected to the No. 1 gear 72.

After the lower die 12 is placed on the workbench 1, the No. 1 motor 21 is started, and the No. 1 motor 21 drives the bidirectional threaded rod 24 to rotate. As the bidirectional threaded rod 24 rotates, the two movable frames 23 on it, which are connected by threads, will move. Since two L-shaped clamps 26 are slidably connected to each movable frame 23, these four L-shaped clamps 26 work together to quickly and firmly clamp the lower die 12, thereby achieving efficient positioning of the lower die 12. In addition, the four L-shaped clamps 26 can flexibly adjust their front and rear positions, further enhancing the convenience and flexibility of use. During the punching operation stage, the No. 2 motor 71 is started, which drives the No. 1 gear 72 to rotate. Since the No. 1 gear 72 is engaged with the No. 2 gear 73 installed on the upper end of the transparent guard plate 75, the rotation of the No. 1 gear 72 will drive the No. 2 gear 73 to rotate, thereby achieving angle adjustment of the transparent guard plate 75.
