我厂引进的国外图纸中有一件铝合金大型阀体,如图1所示。锻这么大的LF2阀体,我厂还是第1次。我厂只有5t和3t以下的自由锻锤,所以只能考虑用锤上胎模锻的方法来生产该零件。根据阀体零件图及其技术要求,并考虑到铝合金胎模锻造的工艺特点作出阀体锻件图。如图2所示。分析阀体锻件形状,分模位置显然应取在图2所注的分模面处。根据有飞边合模锻造时的设备吨位简化 I introduced a foreign plant drawings in a large aluminum body, as shown in Figure 1. Forging such a large LF2 body, I plant is the first time. Our factory has only 5t and 3t free forging hammer, so only consider the method of using hammer on the tire forging to produce the part. According to the valve body parts and technical requirements, and taking into account the characteristics of aluminum alloy forging process forging valve body made of plans. as shown in picture 2. Analysis of the valve body forgings shape, parting position apparently should be taken in Figure 2 Note the parting plane. According to the flash clamping forging equipment when the tonnage simplified
