Abstract

The invention provides a liquid metal forming method, which relates to the technical field of metal processing, and comprises the following steps: placing liquid metal in a liquid state in a reaction container; adding a liquid medium material into the reaction container, wherein the density of the medium material is smaller than that of the liquid metal; a core body set to be in the target shape is placed in a reaction container, and the core body is of a solid structure made of gas and can sublimate at the room temperature; taking out the core body and the metal shell solidified on the surface of the core body; and forming holes in the surface of the metal shell. According to the arrangement, compared with the printing technology in the prior art, the liquid metal forming method implementation device is simple in structure and low in cost, and the manufacturing time can be shortened. In addition, the medium material is arranged, so that when the core body is immersed into the liquid metal, a buffering effect is achieved, the problem of high supercooling degree of the liquid metal is solved, and the liquid metal can be rapidly and uniformly solidified.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a liquid metal forming method. Background technique [0002] Liquid metal has a low melting point and is widely used in the manufacture of products in low-temperature environments. In the prior art, metal printing is used for liquid metal forming. However, the method of forming the liquid metal by printing makes the structure of the entire forming device complex and the cost is high. [0003] Therefore, providing a liquid metal forming method with simple structure and low cost is a technical problem urgently needed by those skilled in the art. Contents of the invention [0004] The invention provides a liquid metal forming method with simple structure and low cost, which is used to solve the defects of complex structure and high cost in metal printing in the prior art. [0005] A kind of liquid metal forming method provided by the present invention comprises steps: ...
