Electromagnetic wave type micro casting and liquid forging integrated 3D metal printing machine

Abstract

The invention discloses an electromagnetic wave type micro casting and liquid forging integrated 3D metal printing machine. The electromagnetic wave type micro casting and liquid forging integrated 3Dmetal printing machine comprises a traditional 3D sand mould printing machine (1), an electromagnetic wave rapid melting metal filling device (4), a micro casting and liquid forging pressure device (5) and an integrated electronic controller (3), wherein a target piece sand mould (2) is printed by the traditional 3D sand mould printing machine (1). A part 3 comprises a master controller (MCU), apulse generator (PG), a solid-state relay (SR), a temperature controller (CNTL) and a converter (TR); a part 4 comprises a nozzle (NZ), a crucible (CR), an electromagnetic wave inductor (EM), a liquidmetal or liquid metal based composite (LQ), a temperature sensor (TS), a ball valve (BV), an exhaust hole (EX) and an electromagnetic valve 1 (E1); and a part 5 comprises compressed gas (A) and an electromagnetic valve 2 (E2). The electromagnetic wave type micro casting and liquid forging integrated 3D metal printing machine achieves dense uniform structure of a workpiece, grain refinement, excellent mechanical property and high anti-fatigue degree of metal, and solves the problems that the cost of the conventional metal 3D printing is high, the labor hour is long and no durable material is printed.

Description

Technical field [0001] The invention relates to the technical field of 3D metal printing, in particular to an electromagnetic wave type micro-casting liquid forging integrated 3D metal printer. Background technique [0002] Since metal is used in the manufacture of many parts and components, metal parts with complex shapes are widely used in aerospace, ships, automobiles, machines, electronics, and medical fields. 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, c...
