这项工作描述了多孔挤压工艺的设计过程。对于相同尺寸的孔，单孔挤压工艺中的冲压力大于多孔挤压工艺中的冲压力。因此，对单孔挤压工艺进行了简化的上限和板坯法分析。从该分析中获得的冲压压力和模具压力用于设计多孔挤出工艺设置。使用有限元方法计算模具中的应力。在此基础上搭建了实验装置并进行了实验研究。
This work describes the procedure for the design of a multi-hole extrusion process. For the same sizes of the holes, the ram force in a single-hole extrusion process is more than in a multi-hole extrusion process. Therefore, a simplified upper bound and slab method analysis has been carried out for a single-hole extrusion process. The ram and die pressures obtained from this analysis are used for designing a multi-hole extrusion process setup. The stresses in the die are computed using the finite element method. Based on this approach, an experimental setup was fabricated and experimental study was carried out.
