Anti-blocking mechanism of metal powder production device for 3D printing

Abstract

The invention discloses an anti-blocking mechanism of a metal powder production device for 3D printing. The mechanism comprises a base, a supporting base is fixedly arranged on the base, a plasma archeating source is fixedly arranged on the side wall of the end, away from the base, of the supporting base, and the output end of the plasma arc heating source is fixedly sleeved with a sleeve; and asliding seat is arranged on the base in a sliding manner, the sliding seat is arranged on the base in a sliding manner through a sliding plate, a sliding groove corresponding to the sliding plate is formed in the base, and a limiting mechanism corresponding to the sliding plate is arranged in the sliding groove. When metal powder for 3D printing is prepared through a plasma rotating electrode method, a metal rod serves as a resistor to be connected into a circuit, the cross sectional area of the metal rod is reduced when the metal rod is consumed, so that the resistance is increased, the current in the circuit is reduced, and therefore a magnetic field around a solenoid is continuously reduced; and therefore, a magnetostriction plate deforms to generate continuous vibration, and the problem that the powder blocks a discharge port is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an anti-blocking mechanism of a metal powder production device for 3D printing. Background technique [0002] With the continuous development of science and technology, more and more new materials have been discovered and produced. There is a magnetostrictive plate, which is a magnetic alloy material made of iron and cobalt materials. When a magnetic field is applied , the material deforms slightly, and when the magnetic field changes, the material vibrates due to the continuous deformation. [0003] In the prior art, when producing metal powder for 3D printing, the plasma rotating electrode method is usually used to produce it. This method is to make a metal or alloy into a consumable electrode, and the end of the consumable electrode is at the same time. Under the action of the axial plasma arc heating source, it melts to form a liquid film, and the liquid film is thrown o...
