Embodiment
With reference to the accompanying drawings and examples, the embodiment to the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
Referring to Fig. 1 to Fig. 4, a kind of metal liquid filling described in a preferred embodiment of the present invention, Plastic Flow compound die
Forging process, technique includes：In a Die, liquid or semi-solid-state metal complete to fill under first pressure effect first
Type, solidification, obtain the blank with formation of parts shape；Applying formed metal after second pressure can force some active modules to produce
Raw movement, discharges some die spaces, while the plasticity for making pre- section of blank and realizing under pressure truly becomes
Shape, finally obtains formation of parts, wherein, first pressure value is less than second pressure value.
The simple T-piece of the present embodiment selected shape is as the typical parts of integrated die forging, and liquid or semisolid fill axle
The vertical cylinder of line, two waney column parts of axis horizontal are by plastic deformation after added metal solidification
Into.Liquid is completed during integral forming or semisolid filling completes plastic deformation again, so will to building mortion
Ask higher, it is more complicated.
The present embodiment integration die forging system, including three major parts：Mould part, pressure control device, fixed company
Connection device.Mould part is the main body of building mortion；Pressure control device controls the movement of movable slider, and is pressed by adjusting it
Power size realizes different speed；Fixed connection apparatus is to connect mould and pressure control device and make mould active type
Core is matched properly with hydraulic cylinder.
The main points of mold design are as follows：
(1) in the mold materials liquid and semisolid die forging forming process of formation of parts, formation of parts connects with molten metal
Touch, to absorb substantial amounts of heat, it is thus possible to because temperature is too high and causes intensity decreases, this material for requiring to select has
Certain intensity, heat resistance and corrosion resistance.Appropriate heat treatment is carried out to mould steel to improve hardness, if hardness is not enough, mould
Tool may be damaged.This experiment formation of parts selects 5CrNiMo.
(2) convex, recessed clearance of touching will be suitably.Concave, convex gap is too small, can be because of punch-pin and the rigging error of cavity plate generation
Collide or bite；Excessive, 6061 molten aluminium alloy can then be sprayed by die clearance, 1. cause danger, 2. produce longitudinal overlap,
Reduce pressure effect, 3. hinder moving down for drift, build-up of pressure loss makes forging's block dimension not enough, and aggravates mould damage, makes
Gap is bigger, causes vicious circle.It is that 0.06-0.1mm is more suitable according to the unilateral gap of practical production experience.
(3) demolding structure can not directly eject product because the shape of part is limited using push rod, but need first to eject
Combined die, then combined die is opened take out forging part.Cavity plate is taken out for convenience simultaneously, in cavity plate and cavity plate die sleeve
Between need to design certain gradient.
(4) exhaust molten metal in itself and pours into during die cavity and will carry some gases secretly, if these gases are not arranged
Die cavity, can hinder metal to fill type, and causing to wrap up in gas, outer surface inside forging has bubble depression, has a strong impact on the quality mould of product.One
As under situation, mould will set steam vent.This experiment is no but sets steam vent, but utilizes and pass through clearance between matrix and punch by gas
Discharge.
T-piece shaping dies operation principle：In shaping, molten metal is poured into combined die first, less
Liquid underfill is carried out under the pressure of drift 3, metal gradually solidifies in filling.Now, hydraulic press is less than or equal to the power of drift
Control pressure outside movable slider, so sliding block is remained stationary as, black region is applied in die cavity holding figure.Continue intensified pressure, metal
Blank increases the pressure of movable slider, gradually more than control pressure outside movable slider, and the metal of formed part will be promoted
Sliding block 6,13 is displaced outwardly, and cavity shape produces change, and cavity space becomes big, and the cylinder (φ 50) for now filling formation is produced
Compressive plastic deformation, two horizontal columns (φ 20, φ 30) squeeze sub- shearing large plastometric set by variable diameter angle and formed.
In the present embodiment, (1) changes the control mode of moving core.Original design realizes control using spring, operationally,
One it is possible that failure and pressure increase with core displacement；Two be that control pressure is small；Three are spring element and install annex
Space-consuming is big, and can not obtain big core amount of movement, to realize die size can be made to become very big, therefore can design
A set of hydraulic system replaces original spring.
(2) increase gradient is to reduce the contact area of cavity plate and die sleeve on the outside of cavity plate, and with positioning finger setting, to control
The formation of overlap, and play a part of reducing the ejection resistance after shaping.
Pressure control device is made up of fuel tank, hydraulic pump, overflow valve, choke valve, six parts of reversal valve and hydraulic cylinder, figure
2 be its schematic diagram.After hydraulic system starts, by the pressure of throttle valve adjustment oil pressure, oil cylinder piston is driven with differently speed
It is mobile, untill meeting the stroke after forcing press continues to press.This set system is controlled left and right two cunnings by two oil cylinders
Block, because the right and left face of cylinder diameter is different, suffered pressure is also different, and we can be increased by this set system
More experimental condition changes, so as to more fully be studied integrated swaging technique.
In order to fixed and connection take over a job movable slider control oil hydraulic cylinder with die design auxiliary equipment, as shown in Fig. 3
's.This set auxiliary equipment is made up of two inner and outer diameter identical large circles, by two threaded guide pillars and nut support
Get up.Annulus above can highly make the center of the center of control cylinder and mould movable slider same by threaded adjusting
One level height.Oil hydraulic cylinder is secured on the annulus that this can be moved up and down.
The checking of the T-shaped part structure property of the present invention is carried out by taking 6061 aluminium alloys as an example.
Density and hardness test is carried out to it in T-shaped 5 point interception 10mm × 10mm × 15mm of part sample.1 point is straight
The contact jaw of footpath 30mm sliding blocks, 2 points are the end face with diameter 20mm shoe contacts, and 3 points and 4 points are respectively two various sizes of
Corner, 5 points are the upper surface with punch. contact.
Microstructure conclusion：The influence that the pattern and size of crystal grain are under pressure with deformation direction, near crystal boundary and portion
Divide the pointing object that some black are occurred in that at crystal grain, these pointing object are some precipitated phases, due to Mg in 6061 aluminium alloys
Content is higher, so containing more Mg2Si phases.
Liquid fills forging part density measurement result and analysis
The density of forging is substantially uniform, but there are still certain regularity of distribution：1st, 5 points are and shoe contact position density
It is relatively low, because being the fore-end of extrusion φ 30mm and φ 20mm cylinders, plastic deformation is not participated in during extrusion, is
Solidified structure in the case of pressure is smaller in filling, so tissue is more loose；2nd, 4 points take part in positioned at corner metal and cut
Plastic deformation is cut, density is larger；With main punch. contact position 3, the pressure being subject to is big, similar Upsetting, so material is relatively caused
It is close；Corner is the pressure for having upper metal to transmit, and by the pressure of the both sides obstruction of frozen metal and oil cylinder, density value
It is larger.The change of side cylinder pressure is to 1,3,5 points of affecting laws it is unobvious, but can see the real density of corner and be in pressure
The trend now increased.
The not real density (g/cm3) of homonymy cylinder pressure
Hardness test
First by forging part carry out solid solution+artificial aging T6 be heat-treated, be solid-solubilized in 525 DEG C of temperature be incubated it is 2 small
When, quenched after taking-up, then in 175 DEG C of timeliness 8 hours.
(1) liquid filling forging part hardness test result following table is test force 100N, pressurize 15s Hardness Measurement Results.
From the point of view of the result of measurement, hardness is similar to Density Distribution variation tendency, and it is to influence the weight of material mechanical performance to illustrate consistency
Want one of factor.Side cylinder pressure is nearly free from influence on the position with punch. contact, and the hardness number of 1,2,4,5 positions with
Increased trend is presented in the increase for surveying cylinder pressure.Because corner generates certain plastic deformation, so this is in whole system
Part takes hardness number in a position maximum, particularly smaller diameter end corner, is to understand plastic deformation degree here by metallograph
It is maximum, is coincide substantially with hardness test result.1st, 3,5 points of hardness number is relatively low, because several places of this in shaping are actual
On be that solidification under certain pressure is formed, the result of this and density measure is also consistent.
Hardness test result
The mechanical property of integrated forging part：Liquid filling method forging part mechanical property is obtained to see the table below.
Liquid fills the mechanical property of forging part
Compared with 6061 typical mechanical properties, it is seen that the performance of forging part has all reached the effect of plastic deformation, and liquid is filled
The mechanical property of mold filling forging is suitable with traditional performance.
There is plasticity in forging part in density, the hardness distribution uniform of integrated forging part, forging part microstructure observation
Deformation structure, the mechanical property of liquid filling respectively reaches and exceeded the performance indications of conventional 6061 forging, it was demonstrated that integration
Die forging is feasible, there is application value.
Described above is only the preferred embodiment of the present invention, is not intended to limit the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is some improvement and
