Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments.
Example (b):
referring to fig. 1-2, the present embodiment is a structure of a precise blanking die for a shaft sleeve plate, and includes a lower die plate 1 for supporting a plate (not shown in the drawings), a stripper plate 2 disposed above the lower die plate 1 and matched with the lower die plate, a male die 3 penetrating through the stripper plate 2, a punching punch 4, and a steel stamp punch 5; the surface of the lower template 1 is provided with a forming cavity 11 avoiding the male die 3, the initial position of the male die 3 arranged in the stripper plate 2 is lower than the initial position of the punching punch 4 arranged in the stripper plate 2, the initial position of the punching punch 4 arranged in the stripper plate 2 is lower than the initial position of the steel seal punch 5 arranged in the stripper plate 2, and the circumferential direction of the male die 3 is provided with an annular chamfer part 31.
The bottom of the lower template 1 is provided with a lower backing plate 12 and a bottom plate 13, a positioning column 6 extending out of the surface of the lower template 1 is further arranged in the lower template 1, and the positioning column 6 is used for positioning the position of a corresponding positioning hole in a plate.
An upper template 21, an upper backing plate 22 and a top plate 23 are sequentially arranged above the stripper plate 2, the top of the male die 3 is fixed at the bottom of the upper template 21, the punching punch 4 is arranged in the upper template 21 and extends into the stripper plate 2, and the steel seal punch 5 is arranged in the upper template 21 and extends into the stripper plate 2.
Before the die assembly, the bottom of the male die 3 is flush with the bottom of the stripper plate 2, and the distance from the bottom of the punching punch 4 to the bottom of the stripper plate 2 is smaller than the distance from the bottom of the steel seal punch 5 to the bottom of the stripper plate 2.
