The invention discloses a kind of polymorphic structure box part extend and extrusion molding dies, it includes Stretching die A, Stretching die B and extrusion die, and it also discloses the forming method of special-shaped thin wall box part.The beneficial effects of the invention are as follows：Take blank is convenient, shaping efficiency is high, forms taper oral area clear angle, dimensional accuracy height, homogeneity of product high.
Description
Technical field
It is particularly a kind of with polymorphic structure box part the present invention relates to the technical field of polymorphic structure box part shaping
Extend and extrusion molding dies and method.
Background technology
Special-shaped thin wall box part is fine aluminium 1060, and adds a profound side inner chamber structure by a flanged (FLGD) tilted conical inner chamber
Into such as the structural representation that Fig. 1 ~ 3 are the special-shaped thin wall box part, it includes main part（33）With main part（33）Phase
Conical section even（34）, conical section（34）Bottom be coupled smooth side（35）.Special-shaped thin wall box part is non-
Axially symmetric structure, there is thin-walled, complicated deep chamber, inside surface roughness requires high, radius is small, taper oral area in inner side is wanted
Ask clear angle, the characteristics of dimensional accuracy is high.Also require that its geometry and size have very high uniformity, technological forming hardly possible simultaneously
Degree is quite big.Because of the requirement such as the special-shaped thin wall box part and surface roughness, dimensional accuracy, uniformity, do not have still on the market
This kind of part similar shaping scheme or technology.At present, typically used for traditional box-like structure part and repeatedly extend or press
It is cast into capable shaping.
However, the shortcomings that repeatedly extending be shaping after inside parts corner fillet it is excessive, inner side taper oral area does not reach
The requirement at clear angle, that is, carry Inner arc after extending（36）, there are the vestige repeatedly extended, roughness, dimensional accuracy, one in this outer surface
Cause property, which does not reach, to be required.And use the shaping scheme of die casting, although can clear angle, dimensional accuracy can also reach requirement,
It is that die casting surface roughness can not reach requirement, tissue is also not fine and close enough, and can not pass through electric performance test.
The content of the invention
The shortcomings that it is an object of the invention to overcome prior art, there is provided one kind takes convenient blank, shaping efficiency height, formed
The clear angle of taper oral area, the special-shaped thin wall box part that dimensional accuracy is high, homogeneity of product is high extend with extrusion molding dies and
Its forming method.
The purpose of the present invention is achieved through the following technical solutions：A kind of extending and extruding with polymorphic structure box part
Mould, it includes Stretching die A, Stretching die B and extrusion die, the Stretching die A include base A, holding pad A,
Punch-pin A, cavity plate A and pop-up A, cavity plate A are arranged at base A top, and the push rod A of insertion cavity plate A grooves is provided with base A,
The top plate A being connected with the top of push rod A in cavity plate A grooves, pop-up A bottom are connected with holding pad A, are set in holding pad A
It is equipped with punch-pin A；
The Stretching die B includes base B, holding pad B, punch-pin B, cavity plate B and pop-up B, and cavity plate B is arranged at base B top,
The push rod B of insertion cavity plate B grooves is provided with base B, the top plate B in cavity plate B grooves is connected with the top of push rod B, on
Support B bottom is connected with holding pad B, and punch-pin B is provided with holding pad B, what holding pad B was even integral by flat board and with flat board
Guide sleeve forms, and guide sleeve is located at the lower section of flat board；
The extrusion die includes base C and pop-up C, and guidance set, base C top are connected between the base C and pop-up C
Portion is provided with punch-pin C, and punch-pin C includes big pylon and small pylon, and small pylon is linked as an entirety and on big pylon with big pylon
Side, formed with annular slope A and shoulder between small pylon and big pylon, the pop-up C fixed cavity plate overcoat in bottom, in cavity plate overcoat
Cavity plate C is installed with, the bottom of cavity plate C grooves is provided with and annular slope A inclination angles identical annular slope B, pop-up C top
The rod member being inserted into cavity plate C is connected with, the bottom of rod member is connected with the upper push pedal in cavity plate C grooves.
It is connected between described pop-up C and cavity plate overcoat and is connected to upper padding plate.
Lower bolster is fixed between described base C and punch-pin C.
Described guidance set includes the guide sleeve being fixedly arranged on pop-up C, the lead being fixedly arranged on base C, guide sleeve
It is set on lead.
The method that described mould is extended with extrusion forming special-shaped thin wall box part, it comprises the following steps：
S1, the first time of blank extend：Blank is first lain against to the groove top of cavity plate A in Stretching die A, then makes holding pad A
Descending with pop-up A, blank is pressed on cavity plate A top surfaces by holding pad A, adjustment holding pad A thrust ensure holding pad A with
Blank between cavity plate A can be slided, then descending punch-pin A, and blank is clamped and continued traveling downwardly predetermined by punch-pin A and top plate A
Height after, you can complete blank for the first time be molded, it is achieved thereby that the first time of blank extend；When fetched, answer pop-up A
Position, then jacks up push rod A, and push rod A ejects blank out of cavity plate A groove；
S2, extend for more than times of blank：Blank after being molded in step S1 opening up is put into cavity plate B in Stretching die B
In groove, descending pop-up B and holding pad B, ensure that holding pad B guide sleeve withstands on the arc sections of blank, then descending punch-pin B,
After blank is clamped and continues traveling downwardly predetermined height by punch-pin B and top plate B, you can complete second of shaping of blank；Gradually
Synchronously successively decrease cavity plate B groove sizes, punch-pin B outer profile sizes and holding pad B outer profile sizes, and repeat step S2 can be achieved
Blank is repeatedly extended, and it is bell-mouthed blank finally to process opening, realizes repeatedly extending for blank；
S3, the blank in step 2 deoiled, is made annealing treatment；
S4, blank extrusion forming：First the opening down punch-pin C for being enclosed on extrusion die of bell-mouthed blank will be carried in step S3
Small pylon on, then the vertical wall section material of blank is expressed to annular by descending pop-up C, the straight wall of cavity plate C grooves gradually downward
On inclined-plane A, blank wall thickness is gradually thinning, with continuing traveling downwardly for pop-up C, between cavity plate C annular slope B and annular slope A
Upsetting pressure goes out conical section, so as to realize the extrusion forming of blank；
S5, smooth side unnecessary on blank after extrusion forming in step S4 cut away, finally process finished product special-shaped thin wall box
Shape part；It is when taking out product, pop-up C is slowly up, while the upper push pedal below rod member is against at the top of product, continue on up
C is held in the palm, finished product is deviate from so as to stay on punch-pin C from cavity plate C, you can easily removes product.
The present invention has advantages below：The present invention takes the purpose that blank is convenient, shaping efficiency is high, reaches clear angle, size essence
Degree is high, homogeneity of product is high.
