Experimental Study on Superplastic Extrusion of Spur Gear
The superplastic extrusion of spur gears wos studied.The manner of extrusion is radial and the experiment material is Pb-Sn alloy.In order to reduce load,the divided flow method was used in the experiment.The experimental results show that it is feasible to machining the spur gear with superplastic extrusion process.The divided flow method has merits in the fields of inducing forming load and improving metal ability to fill in mould,which provides a feasible basis for practice use.
