THE MANUFACTURING METHOD OF PANTA GRAPH USED BY ELECTRIC RAIL CAR

摘要

The present invention relates to a method for manufacturing a pantagrap current collector plate in which electric vehicles receive power from the outside. More specifically, the flatness of the sliding surface of the current collector plate is smoothed when the pantograph current collector plate is moved against the tramline. Compression molding of the pantograph current collector in order to manufacture a current collector plate which wears down while maintaining wear and lowers the transfer rate to the tank wire, and secures a wear area reference line to the current collector plate obtained in the step. Female thread tapping processing step of setting the fixing bolt inserting range in accordance with the step, applying a liquid binding reinforcement to the threads of the female screw formed by the tapping operation and the fixing bolt for installation, and inserting the fixing bolt in accordance with the female screw The manufacturing method of the electric vehicle pantograph collector plate, characterized in that to produce a current collector in stages.
