振动时效在采煤机壳体制造过程中的应用

The application of the process of vibration relief in shell of sheaer

振动时效具有投资少、生产周期短、使用方便、节约能源等特点,并且操作简便,易于实现机械自动化,可避免零件在热时效过程中产生的翘曲变形、氧化、脱碳及硬度降低等缺陷。振动时效对减少和均化残余应力皆有着良好作用,广泛应用于生产实践中,在采煤机壳体制造过程中获益非浅。

Vibration relief has many features such as less invest, short production period, convenient use, energysaving etc. , and easily operate, easy to realize mechanical automation. It can avoid the shortage of warp distortion, oxygenation, decarburization and hardness knock-down created in the course of heat vibration relief. It makes well actions to both reduce remains stress and even them, widely is used in production process, benefits much from the process of shearer production
