Dynamic Position Accuracy Analysis of Paper-converying Grippers in Die-cutting Machine
Each component of die-cutting machine at high speed may produce vibration and die-cutting quality would be affected in different degrees by direct or indirect vibration.Position accuracy of paper-conveying grippers may be an important influencing factor.Under some suitable hypothetical conditions,single degree of freedom no-damp dynamic model was established based on transferring principle of mass and stiffness equivalence and principle of equivalent substitution.Position process has been discussed at high speed,dynamic displacement deviationresponse spectrum has been gotten by numerical computation method in cam resting rang.The result of the analysis and computation shows that position error has an increasing tendency with the increase of the working speed.So it is vitally necessary that the maximum speed of die-cutting machine must be limited to meet die-cutting accuracy requirement when natural frequency of the machine is known.
