Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a sheet metal punching die, including a base 1, a lower left die 2 is fixedly connected to one end of the top of the base 1, a lower right die 3 is slidably connected to the other end of the top of the base 1, the base 1 and the lower right die 3 are jointly provided with a separation mechanism 4 for facilitating the separation of punching waste, and die cavities 5 are respectively opened at the intersections of the lower left die 2 and the lower right die 3;

[0023] The separation mechanism 4 includes a dovetail groove 41, a card slot 42, a dovetail block 43, a mounting rod 44, a slider 45, a spring 46, and an inverted L-shaped rod 47. A dovetail groove 41 and a card slot 42 are respectively opened on one side of the top of the base 1, a dovetail block 43 is fixedly connected to the bottom of the lower right die 3, the dovetail block 43 is slidably connected in the dovetail groove 41, mounting rods 44 are fixedly connected to the front and back grooves of the lower right die 3, a slider 45 is slidably connected to the outside of the mounting rod 44, a spring 46 is sleeved on the outside of the mounting rod 44, the slider 45 and the inverted L-shaped rod 47 are fixedly connected, the longitudinal end of the inverted L-shaped rod 47 is slidably connected in the card slot 42, and the inverted L-shaped rod 47 and the lower right die 3 are slidably connected.

[0024] By setting the various components of the above separation mechanism 4 to cooperate with each other, the punching waste can be conveniently separated and collected after the sheet metal punching is completed in this utility model.

[0025] At the center of the top of the base 1, a blanking port 6 is provided. On the front of the base 1, a push-pull groove 7 and a guiding groove 8 are respectively provided. A collection box 9 is slidably connected in the push-pull groove 7. On both sides of the collection box 9, guiding blocks 10 are fixedly connected. The guiding blocks 10 are slidably connected in the guiding groove 8. At the upper end of the collection box 9, a collection groove 11 is provided.

[0026] The waste materials after punching can be collected through the collection groove 11 provided in the collection box 9, which is convenient for the subsequent recycling of the waste materials.

[0027] At the upper end of the base 1, a mounting plate 12 is installed through four support rods. At the upper end of the mounting plate 12, a servo motor 13 is fixedly connected. At the center of the upper end of the mounting plate 12, a through hole 14 is provided. On the output end of the servo motor 13, a mounting seat 15 is fixedly connected.

[0028] Through the operation of the servo motor 13, the mounting seat 15 can be driven to rotate, so as to adjust the angle of the mounting seat 15.

[0029] At the lower end of the mounting seat 15, a cylinder 16 is fixedly connected. On the output end of the cylinder 16, a support plate 17 is fixedly connected. On both sides of the lower end of the support plate 17, cutting tools 18 are fixedly connected.

[0030] Since the cutting tools 18 are connected to the cylinder 16, the cutting tools 18 can be driven by the cylinder 16 to punch the sheet metal parts.

[0031] The mounting seat 15 rotates in the through hole 14 to adjust the angle of the mounting seat 15.

[0032] The cutting tools 18 are fixedly installed through the mounting seat 15. Thus, by adjusting the rotation of the mounting seat 15, the angle of the cutting tools 18 can be adjusted, and punching at different angles can be performed.

[0033] The blanking port 6 is communicated with the collection groove 11 for collecting punching waste

[0034] Since the blanking port 6 is communicated with the collection groove 11, the waste materials can fall into the collection groove 11 after punching.

[0035] During specific use, the sheet metal parts are placed at a suitable position on the lower left die 2 and the lower right die 3. The cylinder 16 is started. The cylinder 16 drives the cutting tools 18 to move downward, so as to punch the sheet metal parts. The waste materials after punching fall into the collection groove 11 provided in the collection box 9 through the blanking port 6, which is convenient for collecting the waste materials. If the waste materials are stuck in the die groove 5, the inverted L-shaped rod 47 can be moved to make it slide out of the card slot 42, releasing the limit on the lower right die 3. Moving the lower right die 3 can complete the separation of the lower right die 3 and the lower left die 2, so that the stuck waste materials can break away from the die groove 5 and fall in;

[0036] When the sheet metal part needs to be transversely punched, the servo motor 13 can be started. Under the action of the servo motor 13, the mounting plate 12 rotates at an angle, thereby driving the support plate 17 fixed on the output end of the cylinder 16 to rotate, enabling the cutter 18 fixed on the support plate 17 to rotate, so as to perform transverse punching.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
