中文摘要：采用闭式镦锻-空心分流一模两击式的模具结构对圆柱直齿轮的成形过程进行了DEFORM-3D数值模拟，对成形载荷和齿轮充填情况进行分析，从而得出圆柱直齿轮的理论成形范围曲线，该曲线对今后圆柱直齿轮的成形具有一定的指导意义。
英文摘要：The spur gear forging process with closed heading-hollowness distributary die structure was simulated under the DEFORM-3D.The forming load and gear filling conditions was analyed, and forging range curve of parts of the spur gear was obtained，This curve plays a certain guiding role on the spur gear forging.
