曲柄压力机常用曲线的推导与分析

Derivation and analysis of common curves of crank press

以2000kN曲柄压力机为例,绘制曲柄滑块机构运动简图,并对其常用特性曲线进行公式推导,绘制出滑块运动曲线、行程扭矩曲线、行程压力曲线和偏载下许冲吨位曲线,结合相关特性曲线图介绍曲柄压力机的特点及使用过程中的注意事项。为曲柄压力机设计者和使用者提供理论参考依据。

Taking the 2000kN crank press as an example, the motion diagram of the crank slider mechanism has been drawn, and the formula of its common characteristic curve has been deduced. The slider motion curve, stroke torque curve, stroke pressure curve and accessible tonnage curve under eccentric load have been drawn. The characteristics of the crank press and the precautions during use have been introduced by combination with relevant characteristic curve diagram. It provides theoretical reference for the designers and users of crank press.
