Fig. 1 is the structural representation of drift in a kind of blanking punched device of foam of the utility model；
Fig. 2 is the structural representation of punch process in a kind of blanking punched device of foam of the utility model；
Fig. 3 is a kind of structural representation of the blanking punched device of foam of the utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.
Embodiment one：
As depicted in figs. 1 and 2, the blanking punched device of a kind of foam of the present utility model, including vertical slug drift 1,
Drift cutting edge 2, lower template 3, lower template 3 are provided with lower template material-dropping hole 31, and drift 1 coordinates with lower template material-dropping hole 31 and connected during blanking
Connect, drift cutting edge 2 is connected to the bottom side of drift 1, drift cutting edge 2 includes the knife edge 22, sword in the outer knife edge 21 of cutting edge and cutting edge
Mouthful outer knife edge 21 is overlapped with the outer edge extended line of drift 1, in cutting edge the knife edge 22 be connected to the bottom inside of drift 1 and with knife outside cutting edge
Cutting edge of a knife or a sword 21 is connected into knuckle.
Wherein, the knife edge 22 and the bottom of drift 1 composition slug groove 23 in cutting edge.Slug groove 23 is preferably that circular platform type is recessed
Groove.
The length of drift cutting edge 2 is directly proportional to the thickness of stamping material.The length of drift cutting edge 2 is preferably 0.5-1.5mm.
The outer knife edge 21 of cutting edge with the horizontal 90 ° of angles, in cutting edge the angle of the knife edge 22 and the outer knife edge 21 of cutting edge be 30 °-
60°.According to the difference of die cut material thickness, different knife edge angles and height are selected.Knife edge angle is smaller, and otch is more smooth；
