采用试验研究与计算机工艺仿真相结合的方法,对圆柱齿轮闭式温锻成形过程中影响其成形效果的因素——模具结构进行研究,分析模具结构对齿轮成形的影响。结果表明,冲孔连皮设置在齿轮中心孔的中间部位能减小成形时的载荷,而且所受应变也更加均匀。这有利于齿轮成形,可用来指导模具的设计。 In this paper, a combination of experimental research and computer simulation is used to study the influence of mold structure on gear forming, which is the factor that affects its forming effect during the closed warm forging process. The results show that the perforated skin located in the center of the gear center hole can reduce the forming load, and the strain is also more uniform. This is good for gear forming and can be used to guide the mold design.
