Dynamic Design of the Quick Clamping System of the Press Brake
Abstract:The efficiency of changing the upper molds largely influences the efficiency of bending works. In this paper, a hydraulic upper mold clamping system of press brake is designed. Based on the introduction of the operational principle and structural design of the clamping system, a multibody dynamics method is utilized to dynamic simulation of the key components. Finite element analysis is be applied on clamping device to analyze the mechanical properties of the clamping system. The results which come from dynamic simulation and finite element analysis confirm the practicability of the upper mold clamping device presented in this paper.
