Description
Technical field
The present invention relates to a kind of preparation of Model For The Bush-axle Type Parts semi solid slurry and the integrated devices of extrusion casint, belong to material
Science and technology field.
Background technique
Semi-Solid Metal Process, be exactly in metal solidification process, by being vigorously stirred or the control of process of setting,
Obtaining equably left floating the solid-liquid mixed slurries of subsphaeroidal solid phase components in a kind of liquid metal mother liquor, (solid phase components even can
Up to 60%).This semi-solid metal slurry has rheology and thixotropic behavior, i.e. semi-solid metal slurry has flowing well
Property, it is easy to the product more complicated by common processing methods shaping form.This not only non-fully liquid is prepared, but also non-fully solid
The metal paste of state, and the method that it is shaped, are known as Semi-Solid Metal Process.
Semisolid Metal Processing using metal from solid-state to liquid or from liquid to Solid State Transformation during semisolid temperature
Spend the forming that metal is realized in section.Semisolid Metal Processing has many advantages compared with conventional metal forming technology,
And have wide range of applications, semi-solid processing can be achieved in all alloys with solid-liquid two-phase region.And Semi-solid Metal Thixoforming
In combination with a variety of existing processing technologys, such as casting, extruding, forging and stamping and casting.
Semisolid Metal Processing applies also for composite processing, thoroughly solves out-phase material in composite material preparation process
The floating of material, segregation and it is poor with the wetability of parent metal the problems such as, this has been provided for the preparation and forming of composite material
The condition of benefit.
It is that metal is warm from liquid cooled to semisolid that the forming technology route of semisolid Metal Processing, which mainly has two: one,
Degree, then to obtained semi solid slurry direct forming, commonly known as rheological molding；Another is that semi solid slurry is complete
Full solidification, is first prepared into blank, then according to product size blanking, then is reheated to semi-solid temperature forming, is usually claimed
For thixotropic forming.
Wherein semi-solid rheological molding technique be by semi solid slurry direct forming, therefore have save the energy, process it is short,
Production cost is low, high production efficiency, equipment are simple, be applicable in semi-solid processing alloys range it is big the advantages that.Meanwhile process
Oxide inclusion it is few, the recycling and use of waste material can be completed in same workshop.But the preservation of slurries and conveying difficulty are larger,
Forming process situations such as there may be thermal loss.And thixotropic forming is that molten metal is thoroughly cooled to solid phase from liquid phase, cold
But strong stirring or other processing are carried out during, first obtaining has partially solidified semi solid slurry, nascent in slurry
Mutually in subsphaeroidal, further cooling obtains the blank with non-dendritic structure.Then, by obtained blank formation of parts as needed
Quality be split, then again by every piece of blank heating to need partial remelting degree, cast, forged, being rolled or
Extrusion molding.Therefore the disadvantages of it is long that there are processing flows, and energy consumption is high.
Summary of the invention
For the above-mentioned problems of the prior art and deficiency, the present invention provides a kind of Model For The Bush-axle Type Parts semi solid slurry system
The standby and integrated device of extrusion casint.Process flow has not only been greatly shortened in the present apparatus, but also reduces energy consumption, improves warp
Ji property.The present apparatus is achieved through the following technical solutions.
