Abstract

In this paper we present the cold extrusion shaping technology of 20Cr bevel gears. First, we analyzed a series of processing and treatment referring to bevel gear cold extrusion technology and calculated the cold extrusion pressures used for mold design; then, we designed and cold extruded two- or three-ring composite cold extrusion dies with its precise guiding device; and last, we experimentally tested our designed and extruded bevel gear. The results showed that 20Cr bevel gears shaped with cold extrusion have qualified properties and satisfy application requirements within the required error range. This research is of significance in actual cold extrusion production.
