| The aim of this study was to research cold extrusion forming process of the involute inner spline. Based on the structural characteristics of the involute inner splines， came up with two cold extrusion forming technology schemes of involute inner spline. The processes were numerically simulated through Deform-3D， different process of different stages were analyzed. The load-displacement curve of the two schemes， different blank inside diameter and friction coefficient of involute spline forming quality of scheme two and so on. The involute inner spline can be shaped within the allowable range of stress of the die by the two schemes proposed. The process parameters of the process of forming were obtained and the results revealed the deformation mechanism of the involute inner spline during cold extrusion forming process through numerical simulation. The proposed cold extrusion forming process of the involute inner spline has significance for the actual production and other similar parts. |
