Metal amorphous 3D printing conveying device

Abstract

The invention discloses a metal amorphous 3D printing conveying device, and belongs to the technical field of 3D printing technologies. The metal amorphous 3D printing conveying device comprises a first metal sleeve, a second metal / ceramic composite sleeve and a ceramic wire feeding throat pipe; the extrusion force to a metal wire material is increased by arranging protrusions on the surface of anextrusion chain; a spiral solenoid heat exchanger is arranged, a water cooling method is adopted, the cooling speed is increased, and accordingly, the situation that equipment is damaged by the hightemperature is avoided; in addition, wire material expansion caused by the high temperature can be prevented by increasing the cooling speed, and the situation that a sleeve pipe is blocked due to thefact that the wire material is melt too early is effectively avoided; and by arranging an ultrasonic vibrator in the position of a rotary nitrogen spray nozzle, ultrasonic vibration is transmitted into molten liquid metal, structure crystal grains are refined, after metal melt is thrown out by rotating the nitrogen spray nozzle, then, liquid nitrogen is sprayed out, metal liquid drops are quicklycooled, accordingly, the amorphous structure is formed, and the structure property of a printed product is more excellent.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a metal amorphous 3D printing feeding device. Background technique [0002] In recent years, 3D printing technology, as a promising advanced manufacturing technology, has set off a wave of technological innovation. Commonly used 3D printing materials include plastic and metal powder. Fused deposition modeling (FDM) technology uses filamentary plastic materials as the main raw material. The superposition finally forms the product. Amorphous materials have excellent mechanical properties, but it is difficult to form parts with complex structures. 3D printing can solve their forming problems. [0003] When 3D printing amorphous materials, the 3D printing feeding device is an important part of the printer. At present, most of the most common 3D printer feeding devices on the market are air-cooled, and the cooling speed is poor; the heating device is made of fast-heat...
