Investigation of the effect of pre-deformation shape on cold forming properties in the product material in fastener production

Due to product features such as production quality and high surface quality, cold forging extrusion methods are widely used in the of fasteners. Extrudability plays a key role during process is affected by many parameters. Die shape characteristics directly affect deformation. In particular, deformation hardening influenced characteristics. The also significantly affects mechanical properties. this study, effect die on extrudability 20MnB4 (EN 10263-4) low carbon steel was investigated. Additionally, finite element analysis conducted optimize extrudability. Radiuses, angular, radius-angular shapes were experimental analysis. SIMUFACT FORMING software for Both results showed that steels. steels can be optimized with shape. highest homogeneous metal flow obtained sample from Samples an angular lowest feature. Hardness consistent.
