Experimental Study of Hot Extrusion Micro Gear of Brass H62 Xudong Zhou 1, A, Xiangru Liu 2,B 1 Material Science & Engineering College, Henan University of Science & Technology, Luo Yang, 471003, China 2 Physics College& Engineering College, Henan University of Science & Technology, Luo Yang, 471003, China a syuuzhou@163.com, b xiangruliu314@126.com Keywords: Hot Extrusion; Micro-Gear; Brass H62 Abstract.
In the special die set, the split die structure was designed, and the special die materials were chosen, such as the pressure ram was made of tungsten carbide, and the other dies were made of mold materials 4Cr5MoSiV1.
IWAZAKI, GUMA University in Japan successfully squeezed the micro-gears, which the module m = 10μm, number of teeth z = 10 with superplastic materials Al78-Zn [1-2].
In this study brass H62 blank was choose as the extrusion raw material of the micro gear.
