Abstract：

Through the study on the forming process of brake adjust-nut with hollow blind structure, small hole diameter for medium carbon alloy steel 42CrMo4,a precise forming scheme with simple process and low cost was proposed to improve product competitiveness. Two kinds of forming processes were designed based on its special structure, such as reducing process scheme and upsetting process scheme,which were simulated by finite analysis software DEFORM-3D,the metal streamline distributions, loads and forgings structures were studied and compared in different forming processes. At last, a multi-operation precision forming process which combined warm forging, cold backward extrusion, reducing and other forming methods was obtained. Furthermore, the multiple precision forming process was verified by manufacture. A precision forming idea is provided for the formation of the product with multi-step, variable cross-section, core hollow and much more alloy compositions and carbon content.
