Electromagnetic induction type rapid metal melting spray head for 3D metal printer

Abstract

Provided is an electromagnetic induction type rapid metal melting spray head for a 3D metal printer. The spray head is composed of a spray nozzle (R), a crucible (C), a heat insulating layer (A), a medium-high frequency inverter power supply (P), an electromagnetic coil (B), a cooling device (D), a to-be-melted metal (M) and a feeding device (S). The electromagnetic coil (B) passes through the heat insulating layer (A) and surrounds the crucible (C), the cooling device (D) supplies cooling to the electromagnetic coil (B) and the medium-high frequency inverter power supply (P), the medium-high frequency inverter power supply (P) drives the electromagnetic coil (B), the to-be-melted metal (M) in the crucible (C) is rapidly melted due to electromagnetic induction so as to form metal fluid or liquid (L), and the metal fluid or liquid (L) is sprayed out through the spray nozzle (R). High-cost-performance 3D metal printing can be achieved, the energy conversion efficiency is high, the high deposition rate, a small oxidation layer and the higher safety can be provided, rapid printing can be conducted, and manufacturing of large-size metal components can be conducted.

Description

[0001] Technical field [0002] The invention relates to the technical field of 3D metal printing, in particular to an electromagnetic induction fast metal melting spray head for a 3D metal printer. Background technique [0003] Since metals are used in the manufacture of many parts and components, metal parts with complex shapes are widely used in aerospace, ships, automobiles, machines, electronics, and medicine. 3D printing can manufacture complex parts that cannot be processed by traditional processes , the use of 3D metal printing technology can greatly reduce the need for spare parts and save the input cost of storage and related facilities. Large metal components include aircraft fuselages, aircraft engines, aviation equipment, railway carriages, rails, ship hulls, ocean-going ship masts, trucks, cars, nuclear reactor control rods, oil well casings, electro-hydraulic turbines, etc. Small metal components include automotive engines, gears, bicycle components, clocks, co...
