齿顶分流腔结构对直齿圆柱齿轮冷锻成形的影响分析

Influence Analysis of Apical Shunt Cavity Structure on Cold Forging Forming of Spur Gear

冷挤压成形齿轮件具有优异的表面质量和成形精度,而且材料利用率高,符合绿色制造的发展理念,但是过大的锻压力对锻压设备和模具提出了较高的要求,因而,降低锻件锻压力成为行业的研究热点。以直齿圆柱齿轮的冷锻作为研究对象,对比分析了原始模具结构和2种改进模具结构对锻压力的影响,为冷锻模具的结构优化提供依据。

Cold extruded gear parts have excellent surface quality and forming precision,and high material utilization rate,in line with the development concept of green manufacturing,but excessive forging pressure puts high requirements on forging equipment and molds,thus reducing forgings forging pressure has become a research hotspot in the industry.The cold forging of the spur gear was taken as the research object,and the influence of the original die structure and the two improved die structures on the forging pressure was compared and analyzed,which provides a basis for the structural optimization of the cold forging die.
