Specific embodiment
As shown in Figure 1, a kind of semi-solid magnesium alloy high pressure Jet forming machine, including oil pressure pushing meanss 1, nozzle 2, barrel
3, connecting cylinder 4, screw rod 5, check ring 6, driving servo motor 7, feed bin 8, heating device 9, cooling device 10.
Oil pressure pushing meanss 1 include cabinet 1-1, push bearing 1-2 and partition 1-3, and bearing 1-2 level is pushed to run through case
Inside body 1-1, on outer ring of the partition 1-3 fixing sleeve loaded on promotion bearing 1-2, and two confined airs will be divided into inside cabinet 1-1
Between, there are two oil transportation mouth 1-11 for setting on cabinet 1-1, and its opening is located in the cavity of two confined spaces, realize two
A oil transportation mouth 1-11 conveys or extracts respectively hydraulic oil into two confined spaces, and then by pushing partition 1-3 to make to be located at case
Promotion bearing 1-2 in body 1-1 is moved left and right in the horizontal direction.
Nozzle 2, barrel 3 and connecting cylinder 4 are horizontally disposed and are sequentially communicated, and then form sending of communicating of an inside
Expect channel, the outlet diameter of nozzle 2 is the 1/4 of the diameter of barrel 3, and the passage length of nozzle 2 and the ratio of channel diameter are 4:
1, the cabinet 1-1 of oil pressure pushing meanss 1 is fixedly connected with the side of connecting cylinder 4, and screw rod 5 is horizontally placed on barrel 3 and connecting cylinder 4
Inside, the front end sleeve of screw rod 5 are equipped with check ring 6, and end passes through the inner ring for pushing bearing 1-2 and connects with driving 7 axis of servo motor
Connect, the discharge port of feed bin 8 is penetrated through to connecting cylinder 4, heating device 9 be electromagnetic induction heater, and be wrapped in barrel 3 and
The outside of nozzle 2, cooling device 10 are to be filled with the collet of recirculated water, and be wrapped in outside heating device 9；
Barrel 3, connecting cylinder 4 and oil pressure pushing meanss 1 are both secured on pedestal, keep it solid in the operation process of screw rod 5
It is fixed motionless, and servo motor 7 is driven to be fixed on slidable pedestal, so that as promotion bearing 1-2 is in the mistake moved left and right
Cheng Zhong, driving servo motor 7 drive screw rod 5 to rotate also with moving left and right simultaneously.
As shown in Fig. 2, being using the course of work of semi-solid magnesium alloy high pressure Jet forming machine of the present invention, starting driving is watched
Taking motor 7 drives screw rod 5 to rotate, and starting heating device 9 preheats barrel 3 and nozzle 2, by magnesium alloy particles or fragment
By the way that in the investment to connecting cylinder 4 of feed bin 8, the high pressure oil in pressure-oil tank is passed through the cabinet 1-1 close to driving 7 end of servo motor
On oil transportation mouth 1-11 be sent into confined space, at this point, high pressure oil in another confined space passes through the oil transportation mouth of the upper end
1-11 loopback enters in pressure-oil tank, and with the feeding and submitting of high pressure oil, band dynamic dividing plate 1-3 forward end is mobile, and then drives and push away
Dynamic bearing 1-2 forward end is mobile, meanwhile, the high-speed rotation under the drive of driving servo motor 7 of screw rod 5, so that screw rod 5 is continuous
It is mobile to 2 end of nozzle in the case where rotation；Be added to the magnesium alloy material in barrel 3 becomes solid under the heating of heating device 9
The semisolid of liquid two-phase coexistent, then pass through the shear action of screw rod 5, so that magnesium alloy is become spherical from solid phase, and drop its viscosity
Low, mobility increases, and rotates and pushes and during forward end is mobile in screw rod 5, constantly to flowing at nozzle 2 and pass through spray
Mouth 2 sprays, and finally forms magnesium alloy product in mold 11.After completing the process a magnesium alloy product, by converting high pressure
Two oil transportation mouth 1-11 modes are sent into and are sent out to oil, so that screw rod 5 is mobile to the direction far from nozzle 2, at this point, opening cooling dress
It sets 10 recirculated water to cool down to barrel 3, when screw rod 5 returns to initial position, the temperature of barrel 3 has reduced 150
DEG C or so；At this point, putting into new a collection of magnesium alloy material by feed bin 8 again, the processing of next magnesium alloy product is carried out.
Using the high pressure Jet forming machine, constantly heating becomes semisolid during the push of magnesium alloy material,
And before next group magnesium alloy material feeding, the temperature of barrel 3 is reduced, can avoid the heat release of magnesium alloy during transportation
Synergistic effect caused by phenomenon, temperature when reaching material at nozzle 2 is excessively high, influences the molding effect of magnesium alloy；By upper
Mode is stated, can make magnesium alloy when reaching at nozzle 2 in optimal melting semisolid, jeting effect is more preferable, magnesium alloy product
Molding effect more preferably；By the way that the diameter at nozzle 2 is smaller than the diameter of barrel 3 and the design in 2 channel of elongate nozzle, make
Material when reaching at nozzle 2, moment is compressed in the space rapidly reduced, forms huge injection pressure and from nozzle 2
Place's high speed is projected to mold 11, quickly fills with semi-solid magnesium alloy material to each corner of mold 11, and then make magnesium alloy
The size of product is more stable, the higher surface of precision is also more smooth.Using the high pressure Jet forming machine, consuming energy, low, molding is fast,
And magnesium-alloy material quality after molding is more excellent, surface is more smooth, dimensional accuracy is higher, size is more stable, in addition, also processable
More complicated workpiece, such as bicycle front fork of 90 ° of angles, are very suitable in magnesium alloy manufacture field wide popularization and application.
