摘要
分析了热模锻压力机生产的锻件因设备磨损、工装磨损、锻模加工精度、安装规范和错移力等5类比较常见的原因造成错差及其形成机理,并通过多年现场经验针对这5类原因依次用塞规检查压力机导轨间隙、导向杆与导向套配合间隙、用三坐标检查模具精度、制定模具安装规范和模具优化设计,对生产实践及提高锻件质量具有非常重要的意义。
Mainly introduces five kinds of common causes and forming reason of mismatch of precision forging by hot die forging press machine,such as equipment wear,tooling wear,forging die accuracy,nstallation specification and shifting force,and through years of field experience for the five kinds of reasons were checked with feeler gauge press slide clearance,a guide bar and a guide sleeve with clearance,precision,three coordinate inspection dies make die installation specifications and die design.It plays an important role in the production practice and the improvement of the forgings quality.
