中文摘要:分析了挤杆成形过程中挤压坯表面质量较差的原因,并针对传统挤杆模结构上的问题,提出了改进方案并重新设计了模具。结果表明,新模具生产出的挤压坯外形更加合理,表面质量有所提高,并可减少加热火次,对提高生产效率,降低制造成本有积极意义。
英文摘要:Inferior surface equality during bar extruding formation was analyzed. Regarding to unreasonable structure of die, improved design was applied in new die. The results show that new extruded stock has more reasonable shape, better surface quality and reduce the times of heating during forging. New structure die has positive sense in raising production efficiency and reducing the cost of product.
