近年来,国外科技工作者将摩擦学的理论应用于压力加工,形成了一项新的冲压工艺——流体摩擦冲压。在一般的金属压力加工过程中,坯料和模具之间的摩擦状态属于干摩擦或边界摩擦。若能改变金属压力加工过程的摩擦状态,会在很大程度上减弱摩擦力的有害作用,而在许多情况下,流体摩擦的形成可以将摩擦力的阻碍作用变为积极因素,导致金属应力状态的有利改变,使变形过程更容易进行。从而能减少成形工序的次数,提高冲压制品的
In recent years, foreign scientists applied the theory of tribology to pressure processing, forming a new stamping process - fluid friction stamping. In a typical metal press working process, the state of friction between the blank and the mold is dry friction or boundary friction. Changing the frictional state of the metal during the pressing process can greatly reduce the detrimental effect of friction and in many cases the formation of fluid friction can obstruct the impeding effect of the friction force to a positive factor and lead to a metallic stress state The favorable changes make the deformation process easier. Thereby reducing the number of forming steps and improving the stamping product
