本文的目的是研究在变形速度达10-20米/秒的高速锤上开式模锻时所应具备的主要条件。开式模具的主要特点是带有飞边槽,它的几何形状取决于变形条件和承受上下模打击力的模具镜面的面积。随着变形速度的提高,变形金属的热损耗降低,接触磨擦减少,而润滑效果却得到 The purpose of this paper is to study the main conditions for open die forging at high-speed hammers with a deformation rate of 10-20 m / s. The main feature of an open mold is a flash tank with a geometry that depends on the deformation conditions and the area of ​​the mold mirror that withstands the upper and lower mold strikes. As the deformation rate increases, the heat loss of the deformed metal is reduced, the contact friction is reduced, and the lubricating effect is obtained
