DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a stamping die for processing special-shaped parts as Figures 1 to 4 shown, including a fixed lower die base 1 and a movable upper die base 2. An irregular stamping column 3 is installed at the bottom of the movable upper die base 2. A die pressing groove 4 aligned with the stamping column 3 is provided at the top of the fixed lower die base 1 in a counterpoint manner. A transverse groove 5 is arranged inside the fixed lower die base 1. The transverse groove 5 communicates with the die pressing groove 4. A push plate 6 is movably arranged in the inner cavity of the transverse groove 5. A horizontal pushing assembly 7 for moving the push plate 6 is arranged at the bottom of the fixed lower die base 1;

[0023] The flat pushing component 7 includes a servo motor 71 fixed to one side of the fixed lower die base 1. A receiving groove 72 is formed at the bottom of the fixed lower die base 1. The inner cavity of the receiving groove 72 is rotationally connected with a threaded rod 73 through a bearing. The output shaft of the servo motor 71 is fixedly connected with one end of the threaded rod 73. The outer side of the threaded rod 73 is threadedly connected with a connecting block 74 through a threaded sleeve. The top of the connecting block 74 extends upward and is fixedly connected with the bottom of the pushing plate 6. By driving the threaded rod 73 to rotate through the servo motor 71, and then the threaded rod 73 drives the connecting block 74 to translate in the inner cavity of the receiving groove 72 through the threaded sleeve, and the pushing plate 6 is moved by the connecting block 74, ensuring that the pushing plate 6 reciprocates in the transverse groove 5, facilitating the flat pushing of the special-shaped parts in the die pressing groove 4;

[0024] The movable upper die base 2 drives the stamping column 3 to move downward, and the stamping column 3 is clamped with the die pressing groove 4 to punch and cut the material, so that the stamped special-shaped parts directly fall into the die pressing groove 4, and at the same time move downward in the die pressing groove 4. Subsequently, the flat pushing component 7 drives the pushing plate 6 to reciprocate in the inner cavity of the transverse groove 5. By making the pushing plate 6 fit with the special-shaped parts, the special-shaped parts are sequentially moved from the die pressing groove 4 into the transverse groove 5, and then pushed out from the transverse groove 5, which not only ensures the integrity of the special-shaped parts, but also avoids the occurrence of die clamping during the demoulding process of the special-shaped parts, which is fast and convenient.

[0025] A groove 8 is annularly formed at the bottom of the movable upper die base 2. A connecting spring 9 is fixed in the inner cavity of the groove 8. One end of the connecting spring 9 is fixed with a support frame 10. The bottom of the support frame 10 penetrates through the groove 8 and extends outward. Through the arrangement of the connecting spring 9 and the support frame 10, it is convenient to perform pre-limiting on the stamping material, preventing the stamping material from shifting when the stamping column 3 stamps the material, resulting in damage to the forming of the special-shaped parts and affecting the quality of the special-shaped parts.

[0026] The width of the transverse groove 5 is the same as the width of the die pressing groove 4. One side of the pushing plate 6 is in contact with one side of the die pressing column. By limiting the sizes of the transverse groove 5 and the die pressing groove 4, it is convenient to prevent the special-shaped parts from shaking after falling from the die pressing groove 4 into the transverse groove 5, so as to avoid the pushing block being unable to fit with the side of the special-shaped parts.

[0027] Limiters 11 are fixedly arranged around the top of the fixed lower die base 1. Sliding seats 12 are fixedly arranged on the front and back of the movable upper die base 2. The limiters 11 extend into the inner cavity of the sliding seats 12. By sliding the limiters 11 in the inner cavity of the sliding seats 12, it is convenient to align the movable upper die base 2 with the fixed lower die base 1, preventing misalignment from causing the stamping column 3 to be unable to align with the die pressing groove 4.

[0028] Two support surfaces with different heights are arranged on the top of the pushing plate 6. The two support surfaces are connected by an inclined surface. Through the setting of the shape of the pushing plate 6, it is convenient for the pushing block to support the special-shaped parts with different support surfaces when moving in the inner cavity of the transverse groove 5, ensuring that the stacked special-shaped parts are neat.

[0029] At the center of the top of the movable upper die base 2, a mounting post 13 is fixed. A limiting hole is provided on the outer side of the mounting post 13. Through the arrangement of the mounting post 13 and the limiting hole, it is convenient to connect the movable upper die base 2 with the stamping equipment, ensuring the stable output of the movable upper die base 2.

[0030] During specific use, the movable upper die base 2 is connected with the stamping equipment by using the mounting post 13. The movable upper die base 2 moves up and down driven by the stamping equipment. Then, the movable upper die base 2 drives the stamping post 3 to move down to stamp and cut the material. At this time, the stamping material is stamped into a special-shaped part, and the special-shaped part is located in the die slot 4. With multiple stampings, the special-shaped parts in the die slot 4 are stacked in sequence. At the same time, the servo motor 71 drives the threaded rod 73 to rotate, and drives the connecting block 74 through the threaded sleeve. The connecting block 74 drives the push plate 6 to move in the transverse slot 5. When the push plate 6 pushes the downward special-shaped part into the transverse slot 5, the push plate 6 supports the upper special-shaped part. The push plate 6 can only demold and discharge one group of special-shaped parts at a time. As the special-shaped part moves in the inner cavity of the transverse slot 5, the special-shaped parts are pushed out in sequence.

[0031] 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.
