Description
Technical field
Technical field of mold is the utility model is related to, especially a kind of disk fine blanking die.
Background technology
A kind of slim disk, its center have through hole, and clear size of opening required precision is high, and surface roughness value requirement
Low, former technique is made of wire cutting perforate on billot, and former technique process is more, efficiency is low, and cutting on line shaped
Cheng Zhong, because work pieces process internal stress produces size distortion reason, clear size of opening precision is difficult to ensure that.Therefore, people are common
Produce disk on forcing press by the way of fine die stamping billot,, first should be by pressing before punch-pin enters punch-die during punching press
Flitch compresses billot, to improve pressure-plate-force, avoids billot during punching press from moving, holding pad working face is standing to have cross section V-shaped
Raised line, the V-arrangement wedge angle of raised line can form impression in the upper surface of disk, and this can not meet requirement of the people to some products.
Utility model content
The technical problems to be solved in the utility model is：Overcome deficiency in the prior art, there is provided one kind will not produce pressure
The disk fine blanking die of trace.
Technical scheme is used by the utility model solves its technical problem：A kind of disk fine blanking die, including upper bolster
And die shoe, upper bolster are connected with die shoe by guide pin bushing and guide pillar, die shank, punch retainer and recessed are fixed with upper bolster
Mould, the punch-pin stretched into cavity plate endoporus is fixed with punch retainer, is movably installed with and is respectively positioned in cavity plate endoporus on punch-pin
Cyclic spring pad and annular holding pad, punch-die is fixed with die shoe, elastic ring is movably installed with punch-die and annular is moved back
Flitch, the annular holding pad lower surface are provided with convex annular platform of at least one circle around punch-pin, and annular holding pad passes through ring
Shape convex flat platform is to billot binder, and during binder, the lower surface of convex annular platform and billot upper surface be facet, thus reduction
The compression of impression is easily produced on billot.
To reduce convex annular platform lower surface to the compression of billot upper surface, the annular holding pad lower surface is provided with
Convex annular platform of two circles around punch-pin.
Elastic ring and the cyclic spring pad is made by polyurethane rubber.
The beneficial effects of the utility model are：The utility model is simple to manufacture, production efficiency is high, the circle stamped out using it
Piece clear size of opening precision disclosure satisfy that requirement, and disk upper surface does not have impression.

Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of disk fine blanking die as shown in Figure 1, 2, including upper bolster 18 and die shoe 13, upper bolster 18 and die shoe 13
It is connected by guide pin bushing 8 with guide pillar 10, guide pillar 10 is stretched into the endoporus of guide pin bushing 8, is fixed with die shank 1 on upper bolster 18, on upper bolster 18
Punch retainer 3 and cavity plate 5 also are fixed with by some screws 19 and alignment pin 7, punch-pin 2 is fixed with punch retainer 3, it is convex
The upper end of mould 2 offsets with the lower end of die shank 1, and the lower end of punch-pin 2 is passed down through the upper end of cavity plate 5 and stretched into the endoporus of cavity plate 5, movable on punch-pin 2
Be set with the cyclic spring pad 17 and annular holding pad 6 being respectively positioned in the endoporus of cavity plate 5, annular holding pad 6 by some screws 4 with
Cavity plate 5 is flexibly connected, and punch-die 16 is fixed with by some screws 11 and alignment pin 12 on die shoe 13, the upper end of punch-die 16 with
The endoporus of cavity plate 5 is corresponding, and punch-die 16 is provided with punch-pin hole corresponding with punch-pin 2, and elastic ring is movably installed with punch-die 16
15 and annular stripper 9, annular stripper 9 be flexibly connected by some screws 14 with punch-die 16, the annular lower surface of holding pad 6
It is provided with convex annular platform 20 of two circles around punch-pin 2.
The elastic ring 15 and cyclic spring pad 17 are made by polyurethane rubber.
During punching press, upper mould is descending, and annular holding pad 6 and annular stripper 9 are respectively in cyclic spring pad 17 and elastic ring 15
Billot is pressed between cavity plate 5 and punch-die 16 in the presence of elastic force, the subsequent upper end of punch-die 16 enters in the endoporus of cavity plate 5
Row disk profile blanking, annular holding pad 6 is then in the endoporus of retraction cavity plate 5；Upper mould continues traveling downwardly, and punch-pin 2 is by disk through hole fine
Shaping, waste material are fallen into the punch-pin hole on punch-die 16；After the completion of punching, upper mould gos up, and annular holding pad 6 is in cyclic spring pad
Made disk is ejected from the endoporus of cavity plate 5 in the presence of 17 elastic force, annular stripper 9 is in the presence of the elastic force of elastic ring 15
Billot is drawn off upwards, whole blanking process is completed.
For above-mentioned embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this skill
The personage of art can understand content of the present utility model and be carried out, and protection model of the present utility model can not be limited with this
Enclose, all equivalent change or modifications made according to the utility model Spirit Essence, should all cover in protection model of the present utility model
In enclosing.
