穿甲弹尾翼超塑成形工艺与模具的优化设计

SUPERPLASTIC FORMING PROCESS AND THE OPTIMIZATION OF DIE FRAME FOR AN ARMOUR-PIERCING FIN

在文献 [1]研究成果的基础上 ,通过对成形方案的分析优化和试验研究 ,提出了双向挤压成形和凹模镶块轴向移动开模顶出的工艺优化方案 ,并采用带有液压装置的模具结构 ,解决了普通液压机动作少 ,无法实现成形工艺的难题。该成形方案使穿甲弹尾翼成形的自动化程度显著提高 ,产品质量更加稳定 ,劳动强度进一步减轻 ,生产率呈多倍提高 ,电能消耗大大减少 。

Based on the results of previous study , through optimization of the superplastic forming process and further tests, the paper puts forward an optimized scheme of superplastic forming process for an armour-piercing fin. A scheme of two-way extrusion forming and moving ejection in the axial direction of sectional die is adopted. The scheme solves with the hydraulic setting die frame the difficulties arising from limited movements of a general purpose hydraulic press. The forming scheme increases the level of automation in armour-piercing fin forming, stabilizes the quality of products, relieves the work intensity, increases productivity,decreases the power consumption, and meets the demands in mass production.
