Abstract

Fine blanking is a specialized form of blanking where there is no fracture zone when shearing. This is achieved by compressing the whole part and then an upper and lower punch extract the blank. This allows the process to hold very tight tolerances, and perhaps eliminate secondary operations. In the present study, tensile test and numerical simulation has been performed to investigate distribution of deformation and stress of car seat recliner. The commercial ABAQUS/Explicit software was applied for analyzing the stress and strain of the recliner. In analysis, three lock gear has reached the maximum moment on rotational degree of 2.27. This is more than two times than maximum moment of same size recliner, and can be used safely. Therefore, these can use as criterion of actual structural design.
