E die forging is pressurizeed: start when product presents half curdled appearance to pressurize to wheel spoke face; In order to promote spoke performance, this die forging pressurization steps can be carried out 1 to 3 time.
F die sinking: mold cools down, when product solidifies completely, completes the forging of product, and main piston drives mold to move up, and bed die ejects by the ejecting mechanism being simultaneously arranged on bed die lower end, blank and mould separating.
(2) heat treatment, use the die forging of annealing device liquid towards to produce wheel blank and heat-treat, improving product performance also reaches design temperature;
(3) machined, uses machining set-up finishing wheel billet size;
(4) rotary pressing processing, blank top is pressed in the end of core, and rotate with main shaft, utilize the wheel rim moulding material that the spinning running roller applying high pressure of spinning apparatus is reserved in blank edge, rotary billet is advanced along mould by means of external force, rolls gradually and produces plastic deformation and thinning thus obtain high strength, high-precision aluminum-alloy wheel.
Spinning apparatus is see shown in accompanying drawing 2, comprise backform 1, limit shaft 2, core 5, bed die 4 and spinning roller 3, bed die is coaxially shaped with core, core upper center is coaxially shaped with limit shaft, above core, be provided with backform 1 with axially oriented, this backform is used for the axiality being used for limiting wheel blank with limit shaft coaxial cooperation;
In the middle part of core, corresponding outer radial interval, wheel rim position is provided with three spinning rollers; The radius of these three spinning rollers is respectively 20mm, 20mm and 6mm, and the wheel shaft of these three spinning rollers is arranged on mechanical arm end respectively and drives High Rotation Speed by motor.
Spinning apparatus job step is as follows:
