印铁机前规定位铁皮运动仿真分析

Kinematical simulation analysis of front lay location to iron sheet of iron printing machine

针对印铁机在定位接触瞬间产生铁皮碰撞,导致铁皮边缘产生缺陷的问题,以前规挡板为从动件,对前规进行机构运动学分析,把前规转化成铰链四连杆机构和凸轮-摆杆机构,建立各构件之间运动学方程,运用三维仿真软件Solidworks Motion对前规定位铁皮的过程进行运动学仿真分析,通过对8种不同的前规运动规律和铁皮运动规律进行对比分析,得到一种最优的前规和铁皮的运动规律组合.仿真结果表明,在选取最优铁皮运动规律下,前规定位铁皮的接触力最小,撞击最为柔和.

To solve the edge defect of iron sheet due to instant iron collision during the positioning contact of iron printing machine,the kinematics analysis of front lay was carried out with gauge baffle as follower.The front lay was transformed into hinge four-bar mechanism and CAM-swinging rod mechanism to set up the kinematics equation among components. 3D simulation software of solidworks motion was used to analysis the kinematical simulation of front lay location to iron sheet. The motion regularity comparison of8 front lays and iron sheets was conducted to achieve an optimum kinematical combination of iron sheet and front lay. The simulation results show that the minimum contact force is realized with the most mild striking for the optimum regularity of iron sheet.
