Technical background
In current practical engineering material, magnesium alloy is the minimum material of proportion, be only 1/4 of steel, 2/3 of aluminium, the specific strength of magnesium alloy, specific stiffness are all higher than iron and steel and aluminum alloy materials, in addition magnesium alloy also has fabulous shockproof properties, shock-resistant and anti-wear performance, and good machinability, therefore magnesium alloy materials industrially obtains applying more and more widely.China's magnesium reserves and output are the first in the world, and the deep process technology exploitation of magnesium alloy has major economic value.
For meeting the growth requirement of automotive energy-saving emission-reducing, the lightweight of automobile has become the inexorable trend of development of automobile, due to the rotatory inertia effect of wheel, the lightweight of wheel has very important effect for energy-saving and emission-reduction, has remarkable result to the startup of car load, the aspect such as braking ability and oil-saving discharging-reducing.Magnesium alloy vehicle wheel compares aluminum-alloy wheel can reach the remarkable result of loss of weight more than 1/3, and the industrialization technology of magnesium alloy hub is urgently broken through.
Current magnesium alloy vehicle wheel mainly contains casting and forging two kinds of forming technologies.Although casting wheel production technology is simple, production cost is low, cast magnesium alloy wheel also exists the problems such as product poor mechanical property, casting flaw are many, therefore casts magnesium wheel and is only applicable to motorcycle and low-speed vehicle at present, be difficult to use in passenger car.Magnesium alloy vehicle wheel Forging Technology is the new technology occurred in recent years, be in constantly improving, Forging Technology can increase substantially the mechanical property of magnesium alloy vehicle wheel, take wrought magnesium alloy as raw material, exploitation wrought magnesium alloy wheel forming technology, for wheel light quantified goal realize significant.
Existing magnesium alloy vehicle wheel Forging Technology, mainly contains: the once-forming technique of (1) isothermal superplastic die forging; (2) pier thick-repeatedly backward and forward extrusion-enlarging-flange (bulging) technique.Above-mentioned two kinds of main Problems existing of process: the once-forming production efficiency of (1) superplastic die forging is low, and the superplastic temperature interval of magnesium alloy materials is narrow, it is more difficult that mold temperature controls; (2) pier thick-repeatedly backward and forward extrusion-enlarging-flange (bulging) technique exists that technological process is long, needs to mend temperature to blank in production process, overturning process is easy to occur problems of crack.
Summary of the invention
For the problems referred to above, this patent discloses a kind of magnesium alloy vehicle wheel forging forming method, its technological process may be summarized to be " two squeeze one revolves ", and feature part is: 1) heat: circular magnesium alloy blank is heated to forging temperature, mold temperature control with blank isothermal; 2) just extrude: complete the first shaping to spoke and wheel rim in enclosed backward extrusion mode, but shapeless outer rim; 3) extruding eventually: the end completing outer rim in enclosed forward extrusion mode is shaped, completes the backward extrusion of wheel rim position simultaneously and is shaped eventually; 4) internal rolling is shaped: complete the enlarging of wheel rim and the spinning flanging forming of inner rim in internal rolling mode.
The first extrusion process of magnesium alloy vehicle wheel manufacturing process of the present invention carries out just being shaped to spoke and wheel rim position, the shapeless outer rim of first extrusion process, the height of wheel rim straight drum part and thickness are all less than whole extruded stock, first extruding is Closed Extrusion, first extruded stock is without radial overlap, first extrusion die will carry out preheating before initial workpiece extruding, needs to carry out temperature control such as grade to mould in extrusion process.
The whole extrusion process of magnesium alloy vehicle wheel manufacturing process of the present invention carries out whole shaping to spoke and outer rim, final height is squeezed to further to wheel rim simultaneously, extruding is Closed Extrusion eventually, whole extruded stock is without radial overlap, whole extrusion die will carry out preheating before initial workpiece extruding, needs to carry out temperature control such as grade to mould in extrusion process.
The internal rolling operation of magnesium alloy vehicle wheel manufacturing process of the present invention adopts spinning roller to carry out mould pressing to the interior side contacts of wheel blank, and by wheel rim position spinning to the molded line required, and internally spinning flanging forming is carried out at wheel rim position, two spinning rollers (2-1) under the drive of connecting plate (2-4) around central rotation, and axially do feed motion with radial direction, rely on frictional force effect around each axis of rotation (2-5) servo rotary after spinning roller (2-1) contacts with wheel blank (2-2), spinning roller (2-1) carries out axis and radial feed according to preset program, finally realize the laminating of wheel blank (2-2) and mould (2-3), two spinning rollers (2-1) are arranged symmetrically with, wheel blank (2-2) radial force symmetrically, ensure that the dimensional stability of product, mould (2-3) will carry out preheating before initial workpiece internal rolling, need to carry out temperature control such as grade to mould in internal rolling process.
The beneficial effect that this patent brings is: the shaping 1) only completing magnesium alloy vehicle wheel with 3 procedures, and technological process is short, and production cost is low; 2) in this technique just extruding and eventually extruding two-step be Closed Extrusion, due to non-trimming, not only eliminate and follow-uply cut overlap operation, and improve stock utilization; 3) whole production process is One-time forging, and blank does not need to carry out heating for multiple times, reduces energy consumption cost; 4) adopt internal rolling method to carry out wheel rim flaring and inner rim flange, improve the stress condition of blank, effectively can avoid the cracking defect of blank in forming process, be easy to mass production.
