Description
Technical field
The present invention relates to a kind of auto parts mould, especially relate to a kind of mould for automobile rear wall outside plate.
Background technology
Automobile rear wall outside plate is as the indispensable part of body of a motor car, and the stability of its quality is for automotive safety
Property plays particularly important effect.Up till now mould be divided into 4 operations, want four jig frequencies during production, need a large amount of
Operating personnel, production efficiency is the highest, and part quality is not sufficiently stable.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and provide a kind of service life length,
Safe and reliable, the mould for automobile rear wall outside plate of low cost.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of mould for automobile rear wall outside plate, including upper die component, lower mold assemblies and guide pin bushing Guide column component, institute
The lower mold assemblies stated includes lower bolster and lower mold punch, and described upper die component includes cope match-plate pattern and upper mold die, institute
The lower mold punch stated includes drawing punch, edge-cutting and hole-punching punch, flanging and restriking punch and punching separation punch,
Described upper mold die includes dividing with drawing punch, edge-cutting and hole-punching punch, flanging and restriking punch and punching respectively
Drawing die, edge-cutting and hole-punching die, flanging and restriking die and the punching separation die matched from punch,
This mould passes through a matched moulds, completes the drawing to automobile rear wall outside plate, edge-cutting and hole-punching, flanging and restriking and punching
Hole separates.
This mould is continuous combination die, described drawing punch, edge-cutting and hole-punching punch, flanging and restriking punch and punching
Separate punch to be sequentially arranged along material strip feedstock direction.
Eccentric swage and lower eccentric swage, described upper binder is further respectively had on described upper die component and lower mold assemblies
Device and lower eccentric swage are for pushing down material strip when matched moulds, and described lower eccentric swage is used for part top after die sinking
Rise.
The edge of described drawing punch is provided with the blank holder matched with drawing die, and this blank holder uses insert shape
Formula is spliced.
Described upper mold die, lower mold punch and blank holder all use Quenching Treatment.
Described upper die component also includes being arranged on the edge iron block at edge-cutting and hole-punching die side, after matched moulds completes
Edge iron block falls, and coordinates with edge-cutting and hole-punching die and edge-cutting and hole-punching punch, it is achieved the deburring to part.
Described punching separation punch separates die with punching, and to be respectively adopted the Wedge type sidewise punching being mutually matched convex
Mould and die.
Described guide pin bushing Guide column component includes the guide pillar being arranged on lower bolster and is arranged on cope match-plate pattern and and guide pillar
The guide pin bushing of coupling.
Upper mold die and the lower mold punch of this mould have employed Quenching Treatment technology, make at mould stress hardness and bright and clean
Degree is correspondingly improved, eliminate part caused ftractureing by plucking in drawing process, secretly split, wrinkling and draw
Hair, the phenomenon that scrappage is high.
When the present invention works, upper mold is moved, and has upper and lower eccentric swage by tablet pressure when press is depressed with specified pressure
Tightly, then by punch-die, slab is stretched to state on earth, press liter is removed eccentric swage jack-up part, take out
?.
Compared with prior art, the method have the advantages that
Compared with prior art, this mould has the advantage that
(1) service life is long: this mould blank holder and lower mold are walked material part and be have employed Quenching Treatment technology, improves
Case hardness and mold surface finish, thus reduce the normal wear speed of mould, extend mold use
Life-span.
(2) safe and reliable: fineness and the raising of hardness, during production, in drawing process, part walks material uniformly,
It is not easily susceptible to cracking, improves stability, reduce scrappage, significantly promote the quality of part；
(3) reducing cost: blank holder uses block insert type to be spliced, convenient maintenance is cost-effective.Because hardness carries
Height decreases number of times and the cost of the lowest maintenance of mould plucking and normal wear.
Accompanying drawing explanation
Fig. 1 is that the master of the present invention regards cross-sectional view；
Fig. 2 is that the master of edge-cutting and hole-punching punch of the present invention and edge-cutting and hole-punching die regards cross-sectional view.
In figure, 1 is lower bolster, and 2 is cope match-plate pattern, and 3 is guide pillar guide pin bushing assembly, and 4 is drawing punch, and 5 is drawing
Die, 6 is edge-cutting and hole-punching punch, and 7 is edge-cutting and hole-punching die, and 8 is flanging and restriking punch, and 9 is that flanging and restriking is recessed
Mould, 10 is punching separation punch, and 11 is punching separation die, and 12 is bar in lower mold, and 13 is edge iron block.
