摘要
合理布置成形后半球毛坯的壁厚加工余量,并计算超塑成形模具型面的名义加工尺寸。通过分析半球在超塑成形过程中材料变形机理,设计反向预成形模具型面,达到均匀半球毛坯壁厚的目的,使其满足后续加工尺寸的要求。
The machining allowance of the wall thickness of the formed blank hemisphere is decorated reasonably, and the dimensions of the superplastic forming mold surface is calculated. Through the analysis of material deformation mechanism in the process hemisphere superplastic-forming, the reverse direction preforming mold type surface is designed to achieve the purpose of uniform blank wall thickness and to make it satisfy the requirements of subsequent processing size.
