Description
Technical field
The present invention relates to a kind of multifunctional squeezing compression mould for the shaping of alloy in lightweight profile extrusion, more particularly to one kind
Multifunctional extrusion mould structure and method.
Background technology
Composite element makes up for each other's deficiencies and learn from each other in performance, can give full play to the advantage of various materials, turns into modern work
The focus of industry.At present, the solid-state welding technology such as agitating friction weldering, linear friction welding, diffusion welding (DW) and supersonic welding turns into
Manufacture composite element (composite board, the rod formed such as multiple materials such as aluminium lithium alloy, aluminium alloy, magnesium alloy, copper alloys
Material, hollow unit) important method.During using solid-state welding technology manufacture composite element, due to treating soldering
The presence and welded seam area hole of surface contaminant or oxide, the appearance of slag inclusion and softened region, frequently result in welding and connect
Head mechanical properties decrease.
Plastic Forming and solid-state welding technology can be combined as a whole for manufacturing multiple material composite plate by hot extrusion technique
Material, bar and hollow profile.Compared to using solid-state welding technology, production week can significantly be shortened using hot extrusion technique
Phase.At present, using hot extrusion forming process prepare composite board and bar common method be extrusion billet is fabricated to it is compound
Blank, then molding by extrusion is product.This kind of method or can not eliminate pollutant on composite blank internal interface or
Oxide, so as to it cannot be guaranteed that the quality of final extruded product；Or the preparation technology of composite blank is complex, technological parameter
Regulation and control are difficult.It is the ideal side for manufacturing the components such as composition metal plate, bar and hollow profile using multi-blank extrusion technique
Method, but the technical barrier of three aspects is still suffered from using multi-blank extrusion process manufacture composite element at present：When by
In the difference of different materials flow stress, the rheological behaviour of material is increasingly complex and is difficult to regulate and control, therefore composite element
Weld shape and distributing position are difficult to ensure that；Two be due to different materials fusing point, thermal conductivity, linear expansion coefficient, ductility, crystal knot
The difference of structure and lattice constant etc., realizes that the extruding soldering of composite element is more difficult, therefore composite element
Soldering interface performance is difficult to ensure that；Third, composite structure soldering interface easily forms intermetallic compound, during solid-state soldering
Between and the difference of temperature and soldering interface both sides metallochemistry composition can influence the kind of intermetallic compound on soldering interface
Class and structure, therefore in composite material section bar extrusion process, regulate and control composite material section bar interfacial structure and performance is also extremely multiple
It is miscellaneous.As the above analysis, during composite element is prepared using multi-blank extrusion process, the volume of multiple material
The extruding soldering mechanism of distribution and foreign material is key technical problem urgently to be resolved hurrily with interface performance regulation and control, is numerous works
Journey technical staff and the common focus of attention of researcher.At present, still lack it is a kind of can each material of flexible modulation capacity distribution,
The technical parameter such as cross sectional shape of solid-state soldering condition, extruded product, and suitable for manufacture composite hollow section bar, bar and sheet material
And the extruding soldering mechanism of research foreign material and the multifunctional squeezing compression mould and method of interface performance.
