Macropore on general stamping parts plays the role of installation or via hole, can design hole flanging in design process, hole flanging plays
Reinforce or prevent installation part by the effect of friction damage installing component (such as harness), thus Sheet Metal Forming Technology and die design process
Middle design punching-hole flanging need to design two secondary molds, but the increase of the complexity with stamping parts shape and structure, a stamping parts
Required number of molds is with regard to more and more.Not only development cost increase for the design of excessive number of molds, live mould replacing time, punching press
Jig frequency expense is also increase accordingly.Therefore the compactedness of mold design content is more and more important.
General hole flanging position stamping parts technological design is drawing/molding-three sequence of punching-hole flanging, drawing/punching press after molding
After process part processing completes punching by piercing die, hole flanging is completed through plunging die.Two secondary molds need to be designed, when increasing development cost and mold changing
Between, production efficiency is low.
Utility model content
The purpose of the utility model is to provide a kind of punching hole flanging Integral dies, are asked with solving technology in the prior art
Topic, punching and hole flanging process step design can be integrated by it, the exploitation of a secondary mold be reduced, when saving development cost and mold changing
Between, improve production efficiency.
The utility model provides a kind of punching hole flanging Integral die, comprising:
Punching Burring Punch, is fixed on upper die holder, has concentric holes, the punching hole flanging on the punching Burring Punch
There is hole flanging boss on the outer wall of punch-pin；
Hole flanging cavity plate is fixed on the lower die seat, and with flanging bore, the top of the flanging bore has convex with the hole flanging
The hole flanging type face of platform cooperation；
Punching concave die is fixed on the lower die holder, and is set in the hole flanging cavity plate, the two clearance fit, outer diameter
Equal to the diameter of the concentric holes.
It preferably, further include material returned cylinder, the material returned cylinder is mounted in the concentric holes, and the material returned cylinder is stretched
Contracting bar is towards the punching concave die；There is material returned hole in the punching concave die.
Preferably, the material returned hole is up-narrow and down-wide funnel-shaped structure.
Preferably, the outer diameter of the axis collinear of the axis of the telescopic rod and the material returned hole, the telescopic rod is less than institute
State the diameter in material returned hole.
Preferably, the end of the telescopic rod is spheroidal structure.
Preferably, the end of the telescopic rod is conical structure.
Compared with prior art, the utility model has the function of punching and hole flanging simultaneously, passes through concentric holes and punching convex
Punching operation is completed in the cooperation of mould, is completed flange hole technology by the cooperation that hole flanging boss and hole flanging cavity plate turn over pass face, is realized
Punching, one mould of hole flanging are completed, and are significantly reduced mould development cost, are improved production efficiency.

Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and cannot be construed to the utility model
Limitation.
An embodiment of the present invention:As shown in FIG. 1 and FIG. 2, a kind of punching hole flanging Integral die, comprising: punching is turned over
Hole punch-pin 1, is mounted by means of bolts on upper die holder, has concentric holes 2, punching Burring Punch 1 on punching Burring Punch 1
Outer wall on have hole flanging boss 3；
Hole flanging cavity plate 4, is bolted on lower die holder, with flanging bore 5, the top of flanging bore 5 have with
The hole flanging type face 6 that hole flanging boss 3 cooperates；
Punching concave die 7 is fixed on the lower die seat, and is set in hole flanging cavity plate 4, the two clearance fit, and outer diameter is equal to same
The diameter in heart hole 2.
Stamping procedure part is placed on mold, as upper die holder moves down, material pressing core on upper die holder is by stamping procedure part
Positioning is compressed, when upper die holder reaches bottom dead centre, concentric holes 2 and punching concave die 7 cooperation of punching Burring Punch 1 are completed punching and made
Industry, at the same time, the cooperation of hole flanging type face 6 of hole flanging boss 3 and hole flanging cavity plate 4 on punching Burring Punch 1 complete hole flanging operation.
Punching, hole flanging can be completed by a sequence, effectively increase working efficiency, and significantly reduce mould development cost.
It is preferably carried out in mode in one kind, further includes material returned cylinder 8, material returned cylinder 8 is mounted in concentric holes 2, the material returned
The telescopic rod 9 of cylinder 8 is towards punching concave die 7；There is material returned hole 10 in punching concave die 7.By the setting of material returned cylinder 8, when complete
When at punching operation, waste material enters in concentric holes 2, can be by waste material top such as material returned hole 10 by the telescopic rod 9 of material returned cylinder 8
It is interior, mold is discharged by material returned hole 10, in order to allow waste to that mold is smoothly discharged, it is preferable that material returned hole 10 to be designed as
Narrow lower wide funnel-shaped structure, to prevent waste material to be stuck in material returned hole 10.
It is further preferable that the axis collinear of the axis of telescopic rod 9 and material returned hole 10, the outer diameter of telescopic rod 9 is less than material returned hole
10 diameter.The end of telescopic rod 9 is spheroidal structure or conical structure.Waste material can also be squeezed when pushing away waste material in this way
Deformation, keeps its volume smaller, is more convenient for falling out of material returned hole 10.
