摘要
随着大批量功能性冲压零件市场需求的日益增长,高速压力机得到了越来越广泛的应用。为了提高压力机的动态性能,扬锻集团对曲柄式高速重载压力机进行了参数化优化设计。本文结合曲柄式高速压力机原理机构,并对原理机构进行运动学建模,确定出相应的运动学设计参数及约束条件;根据主滑块和曲轴运动周期的关系,在分析模型的基础上,结合运动学设计要求,对结构方案下的高速压力机的传动系统运动学参数进行了优化设计。优化结果表明,在满足行程的前提下,该尺寸参数下的主滑块和副滑块运行过程中加速度较小,有利于动平衡的设计且有助于提高系统动态精度。
With the increasing market demand for high-volume functional stamping parts,high-speed press has been used more and more widely.In order to improve the dynamic performance of the press,the parametric optimization design for the crank-type high-speed and heavy-duty press has been carried out.In combination with the principle mechanism of the crank type high-speed press,the kinematics modeling of the principle mechanism has been built to determine the corresponding kinematic design parameters and constraint conditions;according to the relationship between the main slider and the crankshaft movement period,on the basis of the analysis model,in combination with the kinematics design requirements,the kinematics parameters of the transmission system of the high-speed press under the structural scheme have been optimized.The optimization results show that under the premise of satisfying the stroke,the acceleration of the main slider and the auxiliary slider under this size parameter is small during operation,which is beneficial to the design of dynamic balance and helps to improve the dynamic accuracy of the system.
