Cold forging of gear components by a modified Samanta process

Abstract: Cold forging of toothed components by extrusion is associated with high punching forces and tool loads, which requires the use of expensive and high-strength tool steels. High process forces result into a substantial tool deflection, which significantly reduces the precision of the toothed components. Thus, the development of alternative processes in order to reduce acting process forces in cold forging is of high interest. A potential process enhancement approach is to use a preform operation where the result… Show more

“…Cold forging is an advanced manufacturing technique that is inexpensive and is widely used in the mass production of industrial parts, such as stepped shafts [1,2] and complex gears [3,4]. Although cold forging has developed considerably over the course of more than 70 years, shortening the process chain [5], reducing the number of process steps [6], and developing hybrid raw parts [7] remain areas that warrant further research.…”

“…The application, however, is limited due to the low achievable die filling and gearing accuracy [2]. In previous research, influencing parameters on the material flow such as the shoulder angle [4] and adjustments of the infeed area [5] have already been identified. However, the influence of the material flow on the application relevant component properties was not investigated.…”
