Description
Technical field
The utility model is related to automobile product processing technique fields, and in particular to a kind of drawing die.
Background technology
The cover board of the bends such as the bonnet of automobile is that moulding is carried out by way of drawing, and a monoblock plate is led to
The extruding for crossing cavity plate and punch-pin forms specific curve form, in existing drawing die, when design only with blank holder with it is upper
Extruding force between mould compresses plate, and there are the effects of gravity in the middle part of plate can be to recessed, and the surrounding of plate
After pressure force, the plate among blank holder will produce ripple, will produce fold when cavity plate and punch-pin coordinate drawing
The phenomenon that, cause the product demoulded after drawing not meet processing request, cause process time waste, production efficiency reduce ask
Topic.
Utility model content
For the deficiency in the presence of the prior art, the utility model provides a kind of drawing die, solves existing
Drawing die causes plate to generate ripple when squeezing, and demoulds and causes fold on product, causes process time waste, production efficiency
The problem of reduction.
To achieve the above object, the utility model uses the following technical solution：A kind of drawing die, including lower die,
Upper mold and the blank holder between upper die and lower die are equipped with punch insert in the middle part of the lower die, are offered on the punch insert
Embedding groove is slideably equipped with sliding shoe in the embedding groove；Multiple apical pores are offered in the lower die, multiple apical pores are distributed on convex
The surrounding of mold core；Offer the slide opening with the edge mate of punch insert in the middle part of the blank holder, the bottom of blank holder be equipped with
The corresponding multiple guide rods in position of apical pore；The pressing position of the blank holder is surrounded by multiple positioning plates；The flanging
The locking member for locking blank holder is additionally provided on circle；The table with punch insert and sliding shoe is equipped in the middle part of the lower surface of the upper mold
Face matched cavity plate type face offers location hole corresponding with the position of multiple positioning plates, the upper mold in the upper mold
On be further opened with fastening hole for engaging locking member.
When in use, upper die and lower die are installed on press, blank holder is mounted in lower die, before carrying out plate placement, is led to
The catch bar crossed on press pushes guide rod on blank holder and sliding shoe to move up, and makes blank holder and sliding shoe and lower die
Separation avoids punch insert from influencing the installation of plate.After plate is placed on blank holder and sliding shoe, control upper mold moves down, and leads to
The pressing position crossed in upper mold compresses four sides of plate with the pressing position on blank holder, and the centre position of plate passes through sliding
Block is supported, and after plate is compressed, control catch bar moves down, and blank holder is made to be carried in lower die completely, controls upper mold
Continue to move down, by the cooperation in cavity plate type face and punch insert in upper mold, by deep drawing of sheet at the moulding surface structure of punch-pin.
Compared with the prior art, the utility model has the advantages that：
1, it when blank holder and upper mold are compressed plate, by sliding shoe to being supported in the middle part of plate, avoids
Plate when upper mold and blank holder drive plate to move down and squeeze plate with the punch-pin cooperation in lower die, can be kept away to recessed
Exempt to generate ripple in the middle part of plate, the case where product surface of final molding not will produce fold, it, can in drawing processing
Directly obtain final product so that process time makes full use of, and improves the efficiency of whole process, improves product
Quality；
2, it is locked at by the locking member on blank holder by blank holder is firm after upper mold and blank holder compress plate
It on mould, can be moved down with blank holder, when the moment that plate touches punch insert causing upward impact force, plate be avoided to send out
Raw movement, plate can be deformed according to the moulding surface structure of punch insert during ensureing drawing processing.
