BALL CHAIN DIE MANUFACTURE METHOD AND INDUSTRIAL STRUCTURE

摘要

To provide a fabrication method of ball chain forming die, the fabrication method for reducing fabrication time of the ball chain forming die and maximizing precision of the ball chain forming die at the same time, and a structure of the ball chain forming die fabricated by the fabrication method. The fabrication method of ball chain forming die comprises a preparation step(S1) of preparing a work for ball chain forming die based on a design drawing; a heat treatment step(S2) of performing heat treatment process on the work for the ball chain forming die after the preparation step; a processing step(S3) of performing grinding and high speed precision processing on the work for the ball chain forming die after the heat treatment step; a wrapping step(S4) of performing wrapping on the work for the ball chain forming die to improve roughness of the surface of the work for the ball chain forming die after the processing step; and a completion step(S5) of completing a finished product(34) of the ball chain forming die by performing inspection and surface treatment on the work for the ball chain forming die after the wrapping step, wherein the wrapping step is performed by wiping out the surface of the work for the ball chain forming die.
