The Characteristic Research And The Simulated Design Of Offset Transferring-Sheet Framework

The transferring-sheet framework is an important component, which weightily affects the quality of presswork. It is composed of cams and staffs, whose dynamic capabilities directly influence orientation precision of sheet. There are many parameters working on the dynamics capabilities of transferring-sheet framework, for example, the type of cam movement rule, the geometry parameters and the material of staffs, and the speed of framework, etc. This article combines the task offered by Shanghai Guanghua Printing Machinery Co., Ltd, in which theory analysis of the fixed center lapping transferring-sheet framework and the exploitation of design & analysis are processed. Material content is as follows:(l)The pluralism vector method is adopted to carry through rigidity movement analysis by choosing several movement rules for high speed movement, whose results offer the base of movement integration and dynamics research.(2) The pluralism vector method and rollback method are introduced to figure out the contour, the press angle and curvature of cam after making certain the movement rule of the staff following cam.(3)The dynamic statics analysis of the framework is dealt with for solving the forces of apiece joint and the moments by using d'Alembert principle.(4)According to the establishing method of dynamic convergence parameter model, the elasticity dynamics analysis is executed in order to gain the dynamic angle displacement, dynamic angle velocity and dynamic angle acceleration of the output system.(5)In the environment of Visual C++, the computer model of livelong analysis process is established by MFC, and the design & analysis software of framework is empoldered.
