摘要
为满足曲柄压力机冲头工作性能要求,提出一种基于椭圆齿轮与曲柄滑块机构组合的驱动机构方案。建立该椭圆齿轮曲柄压力机运动学模型,通过Matlab仿真分析椭圆齿轮偏心率、曲柄安装角及曲柄连杆长度比等参数对曲柄压力机滑块速度、加速度以及急回特性的影响规律,从而优化压力机冲头输出特性,为选择符合不同冲压工艺要求的椭圆齿轮压力机设计参数提供参考。
To meet the performance requirements of the crank press punch,a driving mechanism scheme based on the combination of elliptical gear and crank slider mechanism is proposed.The kinematic model of the elliptical gear crank press is established,the influence of parameters such as elliptical gear eccentricity,crank installation angle,and crank connecting rod length ratio on the crank press slider speed,acceleration,and quick return characteristics are analyzed by using Matlab simulation software.The output characteristics of the press punch is optimized,a reference for selecting design parameters of elliptical gear presses which meet different stamping process requirements is provided.
