Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of high barrier part precision punching device, comprise: blank 5, punching bucket 3, jumper bar 1, drift 2, centering ring 3, trimming ring 6, base ring 7, center pad 8 and demoulding block 9, described blank 5 is placed in punching bucket 4, the top of blank 5 is provided with drift 2, the periphery of drift 2 is provided with a circle centering ring 3, described centering ring 3 is arranged between drift 2 and punching bucket 4, and the top of drift 2 is provided with jumper bar 1; The below of described blank 5 is provided with center pad 8, the periphery of center pad 8 is provided with a circle trimming ring 6, the periphery of trimming ring 6 is provided with a circle base ring 7, and described base ring 7 is arranged between trimming ring 6 and punching bucket 4, and the below of described center pad 8 is also provided with one piece of holder module 9.
