发明了一种高纯高致密粉末冶金制品的压扭锻成型方法，其利用压扭锻模具进行操作；压扭锻模具包括主体部，主体部包括上模部和下模部，上模部和下模部依靠导柱导套定位，上模部包括旋转惯性体，主体部还包括驱动上模部上下运动的压力机和驱动旋转惯性体旋转的驱动机构；包括以下步骤：首先对预压后的粉末坯料进行加热烧结，开启旋转惯性体的驱动机构使旋转惯性体高速旋转运动，将加热后坯料置于成型凹模后切断旋转驱动机构并迅速启动压力机使上模部靠近下模部运动，旋转惯性体仅依靠惯性的高速旋转将对生坯施以扭转和锻压加载；旋转惯性体运动停止后加工完成。该发明能够获取少无杂质、高致密度、微观组织优良的圆饼或碗锥类制品。

Invented a high-purity and high-density powder metallurgy product compression torsion forging molding method, which uses a compression torsion forging die; the compression torsion forging die includes a main body, the main body includes an upper die and a lower die, and the lower mold part is positioned by the guide post and the guide sleeve. The upper mold part includes a rotating inertial body. The main body also includes a press for driving the upper mold part to move up and down and a driving mechanism for driving the rotating inertial body to rotate; including the following steps: the powder blank is heated and sintered, and the drive mechanism of the rotating inertia body is turned on to make the rotating inertia body rotate at a high speed. After the heated blank is placed in the forming die, the rotary drive mechanism is cut off and the press is quickly started to move the upper mold part close to the lower mold part. The rotating inertial body only relies on the high-speed rotation of inertia to apply torsion and forging loading to the green body; the processing is completed after the rotating inertial body stops moving. The invention can obtain round cakes or bowl cone products with few impurities, high density, and excellent microstructure.
