Title: Comparative Analysis About Different Processes of Knuckle Hot Extrusion
Abstract: The different processes about knuckle hot extrusion were comparatively analyzed by FEM simulation,which focused on filling capacity,deformation uniformity and flow lines distribution.The results show that the large ratio of height to diameter of the billet is not suitable for knuckle hot extrusion.The billet with large diameter has the best filling capacity of bar.The process of upsetting-extrusion and press has the best filling capacity and deformation uniformity.Deformation mode plays an important role in flow lines distribution of forging and deformation extent has an important impact on flow lines.The best flow lines distribution can be obtained by preform process.The process of upsetting-extrusion and press has the best integrated process performance.
