冲击活塞热挤压工艺及模具设计

The Hot Extrusion Process of Impact Plunger and Mould Design

通过对零件生产制坯工艺的改进,将胎模锻改为热挤压,并在设计热挤压模具时反复试验改进,最终取得良好效果,提高了产品的使用寿命,节约了材料.

After blank making process was changed from loose tooling forging into hot extrusion and with the improvement of its mould design after repeated tests, a good result was produced. The part service life was increased and material was saved.
