Multi-material hybrid forming method and process based on single mold opening and closing, and multi-material component

A multi-material hybrid forming method based on single mold opening and closing, specifically comprising the following steps in sequence:

• loading a metal tube blank into a mold cavity,
• closing a mold, and sealing two ends of the metal tube blank;
• heating the metal tube blank to a first specified temperature;
• bulging the metal tube blank, comprising:
• injecting a first-pressure high-pressure bulging medium into an end port of the metal tube blank at a side, allowing a wall of the metal tube blank to conform to the mold;
• wherein,
• the bulging the metal tube blank further comprises:
• injecting a first-pressure bulging medium into a space formed between an inner wall of the mold cavity and an outer wall of the metal tube blank to control a deformation amount at a local position of the metal tube blank;
• and
• injecting a first material:
• depressurizing and recovering the first-pressure bulging medium;
• and adjusting a temperature of the mold cavity to a second specified temperature, injecting a first material in a liquid or semi-solid state into a first material space formed between the inner wall of the mold cavity and the outer wall of the metal tube blank, and integrally forming and bonding the first material onto the metal tube blank bulged, wherein the first material differs from a metal material of the metal tube;
• and
• performing rapid quenching in the mold, and demolding.
