自动锻压机的床身广泛采用框架式整体床身,床身的应力计算历来是个十分突出的问题。框式压力机角弯矩的普遍公式适用于自动锻压机床身的计算,问题在于载荷受力图的简化模型选择要合理才能使理论计算符合实际情况。符合实际情况满足工程计算要求的理论公式才有实用的价值。本文通过Z41—5型螺母冷镦机床身的应力计算,采用四种载荷受力图的简化模型,将计算结果与实测应力值进行比较,确定出接近实际应力值的最佳方案,以供这类床身应力计算借鉴。诚然,自动机框式整体床身不是“理想刚
Automatic forging machine bed frame widely used as a whole bed, the bed of the stress calculation has always been a very prominent issue. The general formula for angular moment of frame press applies to the calculation of the machine body of automatic forging press. The problem is that the simplified model of load-bearing diagram should be chosen reasonably to make the theoretical calculation accord with the actual situation. Meet the actual situation to meet the engineering requirements of the theoretical formula has practical value. In this paper, through the stress calculation of Z41-5 nut cold heading machine bed, a simplified model of four kinds of load force diagrams is used to compare the calculated results with the measured stress values to determine the best solution close to the actual stress value Class bed stress calculation reference. Admittedly, the overall automatic machine frame bed is not "ideal just
