底排船尾精化毛坯工艺改进实践

Net Shape Forming Process Improvement Practice of the Base Bleed Stern

以某产品底排船尾毛坯为对象,进行了冷挤压成形工艺改进研究,通过模具设计制造控制,合理的选用软化处理参数及冷挤压时的润滑剂,实现该零件冷挤压加工的顺利成形,进而达到了精化毛坯的目的,提高了材料利用率。

Based on the base bleed stern blank of a product as the object,the cold extrusion forming technology improvement research was carried out.Through the mould design and manufacture control,reasonable selection of softening parameters and cold extrusion lubricant,the part was cold extruded smootly which attained the goal of net shape forming and improved material utilization.
