Copper Packaging Production Line With Lifting Platform Load Characteristics And Dynamic Mechanical Properties

"The cathode copper automatic packaging production line project"is aiming at the cathode copper packing our homework behind the technology and equipment of the status quo. Comprehensive application machinery, electronics, hydraulic, precision measurement, computer control and so on the different discipline theory development completed fully automatic packaging production line. Lifting platform is one of the main lifting transportation equipment,The structural forms and hydraulic system layout and control form directly affect the performance of lifting platform and service life. In actual applications,Due to production site dimensional size and mechanical characteristics,Must to fixed hydraulic elevator platform of targeted design. Automatic packaging production line in the copper,Feeding, balance and plastic three stations use fixed hydraulic lift platform,Mainly used for making COINS props up from conveying chain,To realize feeding, weighing and plastic purpose. Therefore, this topic aims to lift platform bearing conditions of static and dynamic mechanical properties,Find its weak links,And optimize improvement,This paper focused on the following job:(1)According to lift platform structure and working principle,Will lift platform for a positive inverted equivalent a slider-crank mechanism,Lifting platform of established mechanism motion diagram,Equivalent mechanical model and mathematical analysis;Using 3d CAD software PRO/E,Established a lift platform of the three-dimensional entity model;(2)In PRO/E will build of the three-dimensional entity model into finite element analysis software ANSYS,Ignore system non-rigid connection,Finite element method to lift platform statics analysis,Get to the highest level when lifting platform lifting lifting platform equivalent displacement,Maximum equivalent stress,Extracted from the conditions of the equivalent displacement,Equivalent stress of convective;(3)PRO/E of using a three-dimensional software kinematics analysis model,Get work process vertical direction for maximum acceleration 1.2mm/s~2.The vertical direction inertia force of gravity relative to the COINS itself can be neglected,So the mechanics analysis lifting platform can be considered inertial force.(4)The finite element model of lifting platform dynamic analysis. Through the modal analysis get the top 10 lifting platform natural frequencies,Principal mode figure,Through the harmonic response analysis got X,Y,Z direction of the harmonic response curve.(5)Lifting platform of production line under counterweight station under impact loading force analysis. Using finite element software ANSYS in counterweight workstation lifting platform to add and subtract the load copper bear analysis,Get by impact load lifting platform in the lift platform displacement curve,Speed curve,Acceleration curve;(6)Through the statics analysis and the dynamic analysis of data,Can see that there is a certain optimization space,In finite element analysis software ANSYS parametric establish lifting platform model, Using ANSYS parametric design language,using First-order method,With all the lifting platform base plate thickness and the thickness of the lift platform for optimized object,The deformation by lifting platform optimization target is optimized.
