Development of Fine Blanking Dies for Forming Small Sized Module Gear
미소 모듈기어의 Fine Blanking 성형금형 개발
Abstract
In recent automotive industries, fine blanking technology widely used in production of components with relatively thick gauges in brake systems, seat recliner, door locks, and auto transmission systems. Due to its advantages to obtain almost final product quality using fine blanking forming process without additional finish machining processes, consequently saving the production costs. In this paper we intended to develope the small sized module gear toothed dual seat recliner sector gear(0.5mm module) for car seats using fine blanking process which needed semi piercing with computer simulation and a lot of try and errors to achieve required accuracy and geometric quality. However through the some corrections of tool geometries with tryout test, we could get successful results.
