我厂在试制一付风冷发动机大型曲轴锻模时,模块尺寸是:1200×650×430(毫米),模块毛坯重3吨,该锻模用于10吨模锻锤,锻模型面结构由终锻槽,压弯槽、凸台,锁扣部分组成。按常规工艺,锻模压弯槽是在XB4450靠模铣床上加工。但由于该靠模铣工作台承载最大负荷为1吨,而曲轴锻模在加工完燕尾,凸台,锁扣以后,还有2.4吨。模块尺寸也大大超过了靠模铣所允许的最大加工尺
Our factory in trial production of a large air-cooled engine crankshaft forging die, the module size is: 1200 × 650 × 430 (mm), the module blank weight 3 tons, the forging die for 10 tons die forging hammer, forging die surface structure by Final forging groove, bending groove, boss, lock part of the composition. According to conventional technology, forging bending groove is in the XB4450 by the milling machine processing. However, due to the model by the milling table load maximum load of 1 ton, while the crankshaft forging die Dove, boss, lock, there are 2.4 tons. Module size also greatly exceeds the maximum allowable size by mold milling
