Description
Technical Field
The invention belongs to the field of liquid die forging of automobile parts, and particularly relates to high-yield hub liquid die forging equipment.
Background
Liquid forging is an emerging metal forming process that has both casting characteristics and is similar to die forging. The method comprises the steps of directly pouring a certain amount of cast metal liquid into a cavity coated with a lubricant, continuously applying mechanical static pressure, utilizing a flowable and forging technology during metal casting, solidification and forming to enable solidified hard shells to generate plastic deformation, crystallizing and solidifying the metal under pressure, and forcedly eliminating shrinkage cavities and shrinkage porosity formed by solidification and shrinkage so as to obtain a liquid die forging part without casting defects;
The current liquid die forging generally adopts the steps of opening a die, taking out alloy liquid from the side, pouring the alloy liquid into a forming cavity, and gradually pressing down by a hydraulic part above the die forging, because the pressurizing effect is best when the metal is in a molten state, the pressurizing starting time is too late, the thickness of a metal free solidification shell is increased, the deformation resistance is increased, the pressurizing effect is reduced, and the quality of a finished piece is influenced.
