Abstract: In order to slove the problem that the coil shearing machine can′t meet shearing quality of thin electrolytic copper foil, a cutting knife institutions based on linkage mechanism of eccentric wheel was studied for the material characteristic of the electronic copper foil. Firstly, the operating principle of the cutting knife institutions was described in detail from the aspects of eccentric wheel transmission mechanism and linkage of the swinging rod. Then the force of cutting knife meshing point was analyzed .Finally , the optimization design of the cutting knife institutions was realized through analyzing the prototype practical measurement data and using Matlab data. The result indicates that the shearing knife institutions improves the shearing copper foil effect for the different thickness of the copper foil by adjusting the technical parameters of swinging rod and tool holder properly, solves problems of corrugation and copper powder in the process of shearing copper, and meets the special requirements of electrolytic copper foil.
