Mold design and process experiment of open die cold extrusion of spline shaft

摘要

in view of the 125 cc motorcycle transmission of spline shaft, spline is discussed in open die extrusion die structure characteristics and the influence of the spline forming mold springback problem, put forward the choice among the formability of open die extrusion into the die Angle, can avoid squeezing into the mold mouth occurs when local upsetting.
