在实验基础上 ,通过挤压力的分析计算 ,论证了牙嵌齿轮挤压成形的单位压力极大 ,模具强度难以满足 ,应设计合理的锻坯 ,以降低单位压力。并指出了最佳锻坯应满足的条件
Based on the experiment, through the calculation and analysis of extrusion force, it is demonstrated that the unit pressure of tooth cogged extrusion is extremely large and the strength of the mold is hard to meet. The reasonable forging billet should be designed to reduce the unit pressure. And pointed out that the best forging blank should meet the conditions
