Improvement of Precision Forging Process for a Outer Cone Gear Ring in Double Cone Synchronizer
The characters of a outer cone gear ring in a double cone synchronizer were introduced,the reasons causing defects were analyzed,the proposals for improving process were given.By changing the section shape,orientation position and die structure as well as adding a discharge slot,the quality of the products meet the technical requirements,the pass rate of the products reaches to 70% or more,and requirements for batch production is met,the die can be used for longer time.
