The Engine Valve Umbrella Head Hot Forging Die Improvement Measures
Abstract:
When using monolithic hot die to forge the umbrella head of valve parts, hot die of a short life. Through the analysis of factors caused by mold, the structure design, mold material, mold manufacturing and use to take certain measures, the production practice showed that die fatigue crack generation and extended time to prolong service life, obviously improved.
