Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the blanking die of the utility model bounce-proof function.
1- formed punch；2- lower template；21- blanking through-hole；3- lower bolster；31- fold-line-shaped air flue；32- bottom outlet；4- gas occurs
Device；5- controller.
Specific embodiment
Combined with specific embodiments below, the content of the utility model is described in further detail, Fig. 1 shows this reality
With the structural schematic diagram of the blanking die of novel bounce-proof function comprising formed punch 1, lower template 2, lower bolster 3 and gas occur
Device 4 etc..Lower bolster 3 is set to the underface of lower template 2, and the two is fixedly connected.Blanking through-hole is offered in lower template 2
21.Bottom outlet 32 and the tapered fold-line-shaped air flue 31 of most latter end are provided in lower bolster 3.Bottom outlet 32 is set to blanking through-hole
21 underface.Gas generating unit 4 is connected by fold-line-shaped air flue 31 with blanking through-hole 21.The most latter end of fold-line-shaped air flue 31
