Description
Technical field
The present invention relates to a kind of decompressor for the processing of automobile panel inner panel and method.
Background technology
During automobile panel inner panel punch process, the depth of drawing die face is larger, and sheet material consumption of raw materials is larger.Existing punching press
Device is single draw mode structure it is impossible to reach the problem of a large amount of loss of effectively solving material.
Content of the invention
The goal of the invention of the present invention is to provide a kind of decompressor for the processing of automobile panel inner panel and method, energy
Enough effectively solving materials are lost problem in a large number, effectively reduce spillage of material.
Based on same inventive concept, the present invention has two independent technical schemes：
1st, a kind of for automobile panel inner panel processing decompressor, drawing die include upper die and lower die it is characterised in that：Also
It is provided with blank holder and lower blank holder, upper mould, upper blank holder, lower blank holder, lower mould from top to bottom set gradually.
Upper blank holder and lower blank holder all can move up and down；Upper blank holder and lower blank holder can close formation binding face, right
Sheet material is clamped.
The edge of lower blank holder is provided with the recessed low profile matching with upper mould, the edge of upper blank holder be provided with aforementioned
The opening that recessed low profile matches.
Type face on upper blank holder is respectively positioned on the large curved surface of blank holder；Type face on lower blank holder is respectively positioned on and pushes
Under the large curved surface of flange.
2nd, a kind of utilize above-mentioned for automobile panel inner panel processing decompressor process for stamping it is characterised in that：
Rise lower blank holder, in rise mould to limit level, blank holder in rise；
Sheet material is placed on lower blank holder, upper blank holder is descending, until upper blank holder and lower blank holder closure, forms binding face,
Sheet material is clamped；
Upper mould is descending, and upper mould is acted on the recessed low profile on lower blank holder edge, and sheet material is carried out with recessed low profile molding；
Upper mould continues traveling downwardly, and upper mould is acted on upper blank holder, lower blank holder integrator and lower mould, completes plate forming.
Sheet material is carried out spacing by alignment pin, is positioned on lower blank holder.
The minimum point of sheet forming is less than the binding face between upper blank holder and lower blank holder.
The peak of sheet forming is higher than binding face 153mm between upper blank holder and lower blank holder, sheet forming minimum
Point is less than binding face 25mm between upper blank holder and lower blank holder.
The device have the advantages that：
Existing single-action drawing die is optimized by the present invention, sets up double blank holders, be up to sequentially provided with down mould, upper blank holder,
Lower blank holder, lower mould, during punching press, rise lower blank holder, in rise mould to limit level, blank holder in rise；Sheet material is placed
On lower blank holder, upper blank holder is descending, until upper blank holder and lower blank holder closure, forms binding face, sheet material is clamped；
Upper mould is descending, and upper mould is acted on the recessed low profile on lower blank holder edge, and sheet material is carried out with recessed low profile molding；Upper mould continues
Continuous descending, upper mould is acted on upper blank holder, lower blank holder integrator and lower mould, completes plate forming.The present invention first passes through down
The recessed low profile molding to the upper and lower both sides of sheet material for the blank holder, that is, the die face of the upper and lower both sides of sheet material is optimized segmentation so that
The global design depth of drawing die face substantially reduces, and on the premise of ensureing crudy, effectively reduces spillage of material.The present invention
Type face on upper blank holder is respectively positioned on the large curved surface of blank holder；Type face on lower blank holder is respectively positioned on the big of lower blank holder
Under curved surface, ensure that the effect of fitting between blank holder and lower blank holder, reliable retention is realized to sheet material.Plate of the present invention
Material is carried out spacing by alignment pin, is positioned on lower blank holder, further facilitates positioning on lower blank holder for the sheet material.The present invention
The minimum point of sheet forming is less than binding face 25mm between upper blank holder and lower blank holder, and compared with existing drawing, depth reduces
Reach 45mm, improve material-saving further and consume effect.

Specific embodiment
As shown in figure 1, drawing die includes mould 1, upper blank holder 2, lower blank holder 3, lower mould 4, upper mould 1, upper blank holder 2,
Lower blank holder 3, lower mould 4 from top to bottom set gradually.Upper blank holder 2 and lower blank holder 3 all can move up and down；Upper blank holder 2 He
Lower blank holder 3 can close formation binding face, and sheet material is clamped.As shown in Fig. 2 upper mould be provided with the first recessed low profile 5,
Two recessed low profile 6, the 3rd recessed low profile 7, the 4th recessed low profile 8, as shown in figure 5, the edge of lower blank holder is provided with
The first recessed low profile 9 of matching with upper mould, the second recessed low profile 10, the 3rd recessed low profile the 11, the 4th are recessed small-sized
Face 12, as shown in figure 3, the edge of upper blank holder is provided with the opening matching with aforementioned recessed low profile.Said mould 1 and upper pressure
Flange 2, is needed flexibly rationally to be split by cylinder location, structural strength and closure, the type face on upper blank holder is respectively positioned on
On the large curved surface of blank holder, described lower blank holder 3 and lower mould 4, need flexibly to carry out by push rod position, structural strength and closure
Rationally split, the type face on lower blank holder is respectively positioned under the large curved surface of lower blank holder.
During punch process, rise lower blank holder 3, in rise mould 1 to limit level, blank holder 2 in rise, sheet material is placed
On lower blank holder 3, sheet material is carried out spacing by alignment pin；Under cylinder promotes, upper blank holder 2 is descending, until upper blank holder 2 with
Lower blank holder 3 closes, and forms binding face, sheet material is clamped；Upper mould 1 is descending, on upper mould 1 and lower blank holder 3 edge under
Recessed low profile effect, carries out recessed low profile molding to sheet material；Then go up mould 1 to continue traveling downwardly, upper mould 1 and upper blank holder 2, push
Flange 3 integrator is acted on lower mould 4, completes plate forming.The peak of sheet forming in related example involved in the present invention
Higher than binding face 153mm between upper blank holder 2 and lower blank holder 3, the minimum point of sheet forming is less than upper blank holder 2 and lower flanging
