abstract

This study is to analyze the extrusion process of a hollow spur gear of magnesium alloys. A design criterion for the die geometry is first proposed for decreasing the extrusion load and increasing the filling ratio at the tooth tip of the product. Then, the Finite Element Analysis is used to simulate the flow pattern of the billet pushing through a port-hole, a welding chamber and finally a die bearing part. From a series of simulation results, the effect of the bridge length, bearing length, and the welding chamber height, etc. on the filling ratio, welding pressure, extrusion load, final temperature, etc. are discussed. Finally, hot extrusion experiments are conducted with a better die geometry to obtain a sound product. The experimental values of extrusion loads and filling ratios are compared with the analytical values to verify the validity of the analytical model.
