Description

A kind of high-strength vehicle parts materials and preparation method thereof
Technical field
The present invention relates to tubing field, more particularly to a kind of high-strength vehicle parts materials and preparation method thereof.
Background technology
Ge great motor corporations of the world reform one after another supply system, carry out worldwide production, global procurement, i.e., to multiple automobiles The buying of parts manufacturer is changed into minority system supplier buying;Module buying is changed into by single automobile part sourcing;By Carry out domestic procurement and be changed into global procurement.Whole-car firm purchase system change, it is desirable to auto parts and components manufacturer constantly with It is to be adapted, not only require that auto parts and components manufacturing enterprise expands oneself strength, improves product development ability, accomplish that system is opened Send out, system is supplied, while also requiring that its shortens the construction cycle, there is provided high-quality cheap products.This change, advances whole world vapour Car parts industry is merged, the process of restructuring.
The market concentration is relatively several years ago higher, car load factory day by day tend to modularity and systematization buying, supplier it Between cooperation it is even closer so that Global Auto components supplying quotient system system gradually to pyramid-like structure develop, by one-level Manufacturer is responsible for whole piece supply chain so that the more specification of the cooperation between supply chain.The enterprise for developing like this, respective Market be all top, they occupy 80% market, have dominated high-end market exclusively.
Ge great auto parts and components manufacturer is applied to auto parts and components and assembly technologies such as space flight, aviation and electronics one after another On, safe practice, electronic technology, power-saving technology and green technology are extensively applied on automobile.Especially with e-mail Breath technology is the new technique of representative, is not only extensively applied on automobile product, and also extend into exploitation design, trial-production, The various aspects such as production and management;Single automobile parts are may not only be applied to, and has been applied to system synthesis.
For reduces cost, dominate the market, many auto parts and components multinational corporationss are one after another to international development.European car Parts manufacturing enterprise carries out internationalized production one after another to overseas investment;North America auto parts and components producer then invests one after another Europe, Also want to the Eastern Europe Market for extending;Japanese Auto Makers also constantly set up in the world the production mechanism of branch of oneself.Newly The focus of emerging Asian market Shi Ge great auto parts and components multinational corporationss competition, China is even more its hotly contested spot.
The theme of the planning of auto industry 12 is to run business into strong one, and the core run business into strong one still will possess core technology, core Competitiveness, strengthens autonomous innovation.In the regular period, the autonomous innovation of car load has been in progress, it is possible to use the existing platform of foreign countries is opened New product is sent out, but platform development is still weakness.The autonomous innovation of auto parts and components is ignored always, and independent brand parts Already by marginalisation, because auto parts and components producer may be few in the representative of two Conferences, this respect is heard in two Conferences over the years to industry Words it is few.With social city, technicalization, hommization development, design that a kind of impact strength is high, tensile strength is high, High-strength vehicle parts materials that elongation at break is high, hardness is high and bending strength is high and preparation method thereof, to meet market Demand, is very important.
