我厂10吨模锻锤生产的曲轴,如图1所示。其结构特点是: (1),拐柄与平衡块之间的开档尺寸K太小,深度C太大,C/K>1.5。 (2),平衡块的体积大,特别是其高度尺寸太大。因此,按常规的弯曲一终锻工艺设计模具时,很难弯曲 I plant 10 tons forging hammer production crankshaft, shown in Figure 1. Its structural features are: (1), the opening handle between the handle and the balance block size K is too small, the depth C is too large, C / K> 1.5. (2), the weight of the balance block is large, especially its height dimension is too large. Therefore, it is difficult to bend when designing the mold according to the conventional bending-final forging process
