我厂受某汽车制造厂委托,试制若干种汽车零件的锻件毛坯。在其中的左、右转向节臂两种锻件的技术准备工作中,我们发现如果按原设计锻件来设计锻模等工装,由于我厂模具加工能力所限,模具制造有一定困难,同时制造出的锻模操作也不甚方便。为此,我们在对其进行工艺分析的基础上,对原设计进行了改进,从而简化了模具制造工 I plant commissioned by a car factory, trial production of several automotive parts forgings blank. In the technical preparations for the two forgings, the left and the right knuckle arm, we found that if we design the forging die and other workpieces according to the original design forgings, because of the limited processing capacity of the die of our factory, the die manufacturing has some difficulties and at the same time, Forging operation is not very convenient. To this end, we process analysis based on the original design has been improved, thus simplifying the mold manufacturing
