Embodiment Construction

[0018] like figure 1 As shown, a laser 3D printing forming amorphous metal component cooling system includes a cooling liquid storage pool 5 and a cooling liquid working pool 6 arranged in a vacuum glove box 1 .

[0019] The cooling liquid storage pool 5 communicates with the cooling liquid working pool 6 through the cooling liquid delivery pipe 7 through the cooling liquid pump I9, and the cooling liquid delivery pipe 7 is provided with a control valve 10 for adjusting the flow rate of the cooling liquid. Driven by the coolant pump I9 to flow from the coolant storage pool 5 to the coolant working pool 6, the flow rate is regulated by the flow control valve 10;

[0020] The coolant working pool 6 communicates with the coolant storage pool 5 through the coolant return pipe 8 through the coolant pump II 9, and the coolant is driven by the coolant pump II 9 from the coolant working pool 6 to the coolant storage pool 5 flow;

[0021] The worktable 4 is installed in the cooling l...

Abstract

The invention discloses a cooling system for an amorphous metal member formed in a laser 3D printed manner. The cooling system is characterized by comprising a cooling fluid storing tank and a cooling fluid working tank; the cooling fluid storing tank is communicated with the cooling fluid working tank through a cooling fluid conveying pipe and a cooling fluid returning pipe; and a work bench is arranged in the cooling fluid working tank, and the periphery of the work bench is surrounded by a plurality of layers of circulating cooling water pipes. The invention further discloses a cooling method of the cooling system. The liquid level of cooling fluid is always lower than a laser printing layer and kept at the preset height by controlling the rising speed of the liquid level of the cooling fluid, so that the molten pool heat of the metal member can quickly flow to the cooling fluid through the a metal base body. The circulating cooling water pipes can take the heat of the cooling fluid away in time, and the temperature of the cooling fluid is reduced. By means of the cooling system, the manufactured metal member can be always kept in the specified temperature, the molten pool heat can be quickly and efficiently radiated, and melt is prevented from crystallizing. Thus, the amorphous metal member can be obtained.

Description

technical field [0001] The invention belongs to the field of laser 3D printing, and specifically relates to a cooling system and a cooling method for realizing the preparation of amorphous metal components by laser 3D printing technology. Background technique [0002] Amorphous metals combine many excellent properties, such as high strength, high hardness, wear resistance and corrosion resistance. These excellent properties make it have broad application prospects in aerospace, automobile and ship, armor protection, precision instruments, electric power, energy, electronics, biomedicine and other fields. However, the size of the amorphous metal produced by the copper mold casting method commonly used at present is only centimeter-level, which seriously restricts its engineering application. In addition, due to the serious room temperature brittleness of amorphous metals, it is difficult to machine at room temperature, so it is difficult to obtain sophisticated and complex a...
