Description
Technical field
The present invention relates to Al alloys andMg alloys extrusion forming technology, be specifically related to a kind of almag wheel hub former.
Background technology
The development advanced by leaps and bounds along with Global Auto industry, automotive light weight technology has been brought into schedule.In order to alleviate automobile certainly
Heavy sensation of the body amount, improves fuel-saving efficiency, reduces exhaust pollution, it is ensured that automotive safety so that it is serviceability is more excellent.Light structures material
Material (such as Al alloys andMg alloys etc.) demonstrates huge superiority, especially magnesium alloy, not only light weight on automobile, and specific strength is high, and
And damping capacity is good, it is for manufacturing such as the good damping material of automotive hub etc..
Magnesium alloy has abroad been used to manufacture automotive hub.Its technique has low pressure casting method, gravity-assist pouring method and die forging rotation
Platen press etc..The first two technique wheel molecule coarse grains to making, Shrinkage cavity is many, and scrappage is high；Latter die forging, rolling
Pressure, spinning process, have very big breakthrough in quality, the wheel hub intensity of making, and toughness is greatly improved, but manufacturing cost is high,
Its operation is many, and mould is many, and equipment requirements is high, and the magnesium alloy vehicle wheel price of production is high, is only used for racing car and high-grade sedan-chair
Car, hardly enters in general-utility car and applies.And domestic at present rarer manufacturer production magnesium alloy hub, Technology uses
It is still low pressure autofrettage and gravity casting method.
Chinese patent application 101491873 discloses two step plastic forming methods of a kind of automotive hub and supporting molding thereof
Mould, the open first step of this patent: blank is put into and uses fashion of extrusion first to mold spoke part also in extrusion molding dies
Mold the front and rear wheel edge portion of wheel rim simultaneously；Second step: preformed member is put into forward and backward for wheel rim wheel rim in flaring die
Flare formation of part.The enlarging of this forming method and flanging process can be with molding vertically hung scroll products of mid portion in cylinder
Product.Such as hub of motorcycle, but the vertically hung scroll of automotive hub links together with week rounded edge in upper surface.Front rim is expanded by second step
Mouth flange causes hales vertically hung scroll, and easy spalling is damaged, it is difficult to molding.This invention preforming inner rim portion is straight line tubbiness.It is squeezed into
After type, shrinkage after rectilinear cylindrical shape Al alloys andMg alloys blank flatulence of heat type, tightly encase straight barrel type core rod, in knockout course, owing to lacking
Weary draw taper.(Al alloys andMg alloys draw taper is typically more than 3 °) eject difficulty, make blank capping deform.Use edge simultaneously
Guide runner mould comes enlarging, flange molding, owing to enlarging flange (expanding as big mouth from osculum) deformation coefficient is relatively big, easily ftractures,
Difficult forming, yield rate is low.
