摘要:
针对CH1018转向节锻件,基于其形状、结构和锻造成形工艺,分析了其在模锻中的成形难点, 并结合锻造工艺方案及主锻造设备吨位的计算,对预锻模型腔及其飞边槽进行了优化设计,飞边槽采用双仓结构,飞边桥间隙由4 mm优化至3 mm,桥宽由10 mm增加至12 mm,并应用到实际批量化生产制造中。优化设计后采用机械压力机并结合制坯模具,对制坯、预成形工步进行了简化, 得到的锻件充填效果好、结构紧凑、材料利用率高、生产效率高,产品合格率由95.6%提高至99.2%。此设计实例为叉孔类复杂锻件的成形提供了一种在机械压力机上制坯与锤上模锻相结合的方法。
For steering knuckle CH1018 forgings, based on its shape and structure as well as forging process, the forming difficulties in die forging were analyzed, and combined with forging process scheme and main forging equipment tonnage calculation, the pre-forged die cavity and the flash groove were optimized and designed. Then, the flash groove was designed as the double storehouse structure, the flash bridge clearance was optimized from 4 mm to 3 mm, and the bridge width was increased from 10 mm to 12 mm. Finally, the optimized design method was applied to the practical mass production. After the design optimization, the blanking and pre-forming steps were simplified by means of mechanical press combined with blanking mold, and the forgings were obtained with good filling effect, compact structure, high material utilization rate and high production efficiency, and the qualified rate of products were increased from 95.6% to 99.2%. Thus, this design example provides a method for forming complex forgings with fork hole by combining blanking on mechanical press with hammer die forging.
