Abstract

The invention relates to a brand-new high-requirement mechanical part production device, in particular to a device for forging liquid metal through ultrahigh-pressure nitrogen. A means of forging metal liquid by using ultrahigh-pressure air is adopted, high density of the mechanical parts is achieved, crystal grains are reduced, and therefore the tensile strength, the ductility, the corrosion resistance, the scouring resistance, the high temperature resistance and the like of metal products are greatly improved. The device comprises a liquid nitrogen tank (1), a first one-way valve (2), a plunger pump (3), an oil cylinder (4), a second one-way valve (5) and a liquid metal pressurization device (6), the liquid nitrogen tank (1), the first one-way valve (2), the plunger pump (3), the second one-way valve (5) and the liquid metal pressurization device (6) sequentially communicate with one another, and the plunger pump (3) is driven and pressurized by the oil cylinder (4); and the liquid metal pressurization device (6) comprises a barrel (7), a cock (8), a sealing assembly (9) and a liquid nitrogen gasification generating device (10).
