Process Design in Cold Forging of a lnner Cylindrical Pulley for Automobile Airconditioner
자동차 냉방기용 내부 풀리의 냉간 단조 공정 설계
Abstract
The inner pulley is automobile component used as airconditioner clutch assembly. in cold forging of the inner pulley . the design conditions are the same between inner length and outer length, the uniform hardness and the no shape change in inner fillet radius due toa piercing. In industries, the design of forging processes is performed based on an experience-oriented technology, that is, designer's experiences and expensive trial and error. Using the rigid -plastic finite element simulation, we propose the optimal process conditons and design of preform or redesign of final product shape without defects prodicted by metal flow, distribution fo strain, forging load during forging processes form initial workpiece to final product.
