[0005] Preferably: the first die core corresponds to the first trimming die and is used to remove the external flash of the triangular ring.

[0006] Preferably: the second die core corresponds to the second trimming die and is used to remove the internal flash of the triangular ring.

[0007] Preferably: the cross section of the convex platform is trapezoidal.

[0008] Preferably: the trimming die female die is fixed on the lower backing plate through symmetrically arranged mounting counterbores, and positioning blind holes A are symmetrically arranged on both side wall surfaces of the trimming die female die.

[0009] Preferably: positioning blind holes B are symmetrically arranged on both side walls of the trimming die male die.

[0010] Compared with the traditional structure, the beneficial effects of the present utility model are as follows: the structure is simple, the operation is safe and reliable. The internal flash and external flash of the triangular ring are respectively removed by two trimming dies. After the flash is removed, the product can directly enter the next process without grinding, avoiding the cracks and performance defects generated by flame cutting, achieving the purpose of improving production efficiency and saving costs. By designing the surfacing edge, the hardness and blanking strength of the edge are increased, the service life of the die is improved, and the production cost is reduced.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below.

[0019] Referring to the attached drawings, a trimming die for a high-strength triangular ring accessory includes a trimming die female die 6 and a trimming die male die 3, characterized in that: the trimming die female die 6 is arranged on the base die set 1 through a lower backing plate 2, the trimming die female die 6 includes a female die body 61, a first trimming die 62 and a second trimming die 63 are arranged on the female die body 61, a cavity A623 in the form of a through hole is arranged at the center of the first trimming die 62, the cavity A623 is a triangular ring structure, a convex platform 621 extending outward with a matching shape is arranged at the edge of the cavity A623, a built-up cutting edge A622 is arranged at the edge of the cavity A623, a cavity B631 matching the outer edge of the triangular ring is arranged at the center of the second trimming die 63, the trimming die male die 3 includes a male die body 31, a first die core 32 and a second die core 33 protruding downward are arranged on the male die body 31, and built-up cutting edges B34 are respectively arranged at the outer edges of the bottoms of the first die core 32 and the second die core 33.

[0020] In this preferred embodiment, the first die core 32 corresponds to the first trimming die 62 and is used to remove the external flash 5 of the triangular ring.

[0021] In this preferred embodiment, the second die core 33 corresponds to the second trimming die 63 and is used to remove the internal flash 4 of the triangular ring.

[0022] In this preferred embodiment, the cross-section of the convex platform 621 is trapezoidal.
