Description
Technical field
The invention belongs to punching press deep-drawing technique field, it is especially a kind of device improving punching press drawing part evenness of wall thickness
And method.
Background technology
Drawing is exactly substantially the material of blank flange portion gradually to be transferred to the process of barrel, during transfer
The material of flange, due to being acted on by drawing pressure, produces tension in radial direction, and produces compressive stress in circumference.In tension and
Under the collective effect of compressive stress, the metal of flange portion produces plastic deformation, and constantly flows in die and become cylindrical member, due to
Barrel material thickness under action of pulling stress is thinning, and the thickness of barrel material presents the trend of from top to bottom more and more thinner, and
At cylinder bottom, fillet part thickness is the thinnest.Be gradually increased with drawing depth, finally cylinder bottom fillet position cracking so that
The drawing depth shaping eventually is restricted.And due to localized necking, it is even to result in whole cylindrical member wall unevenness, cylinder bottom fillet
Position relatively thin thus reduce its use during intensity.
In order to make up the intensity decreases brought by wall thickness reduction, need to increase overall wall thickness, and after this is produced
Fruit is exactly that part quality increases, and this commercial production theory with current energy-conservation loss of weight is disagreed, for needing by mitigation vehicle body
Weight and reaching reduce particularly important for the automobile industry that consumption of petroleum and greenhouse gas emission are target, simultaneously for
For aerospace field, the loss of weight of parts is always the target of researcher struggle.For this reason, production work persons are to carry
The evenness of wall thickness of high punching press drawing part have also been made many researchs.
In existing technology, for example, the patent of Zhang Yu（CN204135174U）In describe a kind of aluminum cylindrical member local

Mould obtains the preform of certain depth and shape, then application upsetting squeeze mould by preform punch and kicker work
Increased by the local that material is realized in upsetting squeeze with lower, therefore obtain the aluminum blank of Varying-thickness distribution, that is, in advance in drawing stress
The thickness local of material at this is increased, so in drawing process on blank corresponding to the big and thinning serious region of thickness
In, still there is enough material thick, thus avoiding ftractureing after material of partial thickening is thinning under action of pulling stress at this.This kind of
Blank-making method is there is problems that need the strict depth controlling prefabricated blank, if dealing with improperly easily during follow-up upsetting squeeze
Lead to the folding of plate due to Compressional buckling, and upsetting squeeze process convex mould has higher wanting with the routing motion of kicker
Ask, otherwise just cannot obtain Varying-thickness base.
Chen Tan and et al. patent（CN103801608A）In describe a kind of not thinning deep-drawing technique of little flange cylindrical member,
The feature of this patent is that the heating and softening that first blank of drawing is carried out with material is processed, and carries out specific acid to blank
Property solution washing and surface embrocate lubricating oil, it is right to need after carrying out the deep-drawing technique of multi-pass and every time drawing afterwards
Drawing part is made annealing treatment.There is the defects such as early stage blank preparatory process is relatively complicated in the method, can not enter for some
For the material of row heat treated, this technique should not use.

Manufacturing process, the feature of this patent is to be filled with liquid from the top of plate first, when making plate that plastic deformation, one section of pressurize to occur
Between, positive bulging goes out the performing member of certain altitude, and removal upper liquid is passed through into concave die cavity and has certain pressure afterwards
Liquid, makes performing member that plastic deformation occurs in the presence of punch, discharges the liquid of concave die cavity, so that panel beating is equal simultaneously
Homogenize deformation.The method is there is problems that be difficult to be accurately controlled preform by fluid pressure highly and descending in punch
During need between the descending amount of precise control punch and the decrement of concave die cavity liquid relation, because performing member leads to
Cross bulging process to obtain, therefore performing member has had a certain amount of thinning, and the sealing to mould in whole forming process
Property has higher requirements, and production cost is too high.
The eighties in 20th century, the method referred in topping up it is proposed that anti-inflation hydro-mechanical drawing is industrial on the basis of hydro-mechanical drawing
Under the initial pressure effect of room fluid media (medium), there is bulging in sheet material, and obtain reservation shape by the constraint of mould, afterwards one
Determine under liquid chamber pressure plate and carry out with punch motion that liquid filling deep-drawing forming is in opposite direction, it is attached that larger pre- bulk is easily caused die mouth
Nearly folding of material, leads to part forming failure, thus limiting deflection and the performance of part, meanwhile, at preform and end
In forming process, the sealing of mould is had higher requirements, this will increase the manufacturing cost of mould processing.
Therefore, a kind of new technique improving punching press drawing part evenness of wall thickness of exploitation, can make up all in prior art
As higher in punch and kicker motion quality of fit, the defect such as operation is excessively loaded down with trivial details, can solve the problem that punching press drawing part wall thickness subtracts again
Thin serious problem, breaks through the restriction of drawing depth in traditional deep-drawing technique, and the use intensity improving drawing cylindrical member has depth
