套筒胎模闭式模锻中,正确的选择模锻设备吨位和合理的设计模具,是保证生产过程顺利进行的关键,通用计算模锻力的方法,由于各种简化和假设,往往使计算结果与生产实际有较大的出入。本文介绍如何通过实验方法来测定套筒胎模闭式模锻单面法兰锻件时,接触表面上特征点的正应力值及侧表面上特征点的正应力值,从而为较简单较准确的选择模锻设备吨位及设计模县提供了可靠的依据。
Sleeve mold closed die forging, the correct choice of forging equipment, tonnage and reasonable design of the mold is to ensure the smooth progress of the production process the key to universal forging force calculation method, due to various simplifications and assumptions, often make the calculation The results and the actual production have a greater discrepancy. This article describes how to determine the normal stress of the feature point on the contact surface and the normal stress value of the feature point on the side surface when the closed mold forging single-faced flange forging die is experimentally determined, so as to be relatively simple and accurate Select forging equipment tonnage and design mode county provides a reliable basis.
