Abstract

The invention relates to a rod sealing structure of powder making equipment, comprising a base for fixing the sealing part, an inner sleeve installed on the inner diameter of the base and capable of moving in the axial direction, and a driving lever for moving the inner sleeve. A limit plate that restricts the moving position of the inner sleeve; a rod connecting sleeve is inserted in the inner sleeve, there is a gap between the rod connecting sleeve and the inner sleeve, and there is an inner sleeve outer sleeve between the inner sleeve and the base. sealing ring. The rod sealing structure of the pulverizing equipment of the present invention adopts a radial sealing method, which is easy to operate and easy to realize automatic control. This method has no force on the driving device and will not cause damage to the driving device.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to powder making equipment, in particular to a rod sealing structure of powder making equipment. Background technique [0002] In the prior art, methods for producing metal powder include mechanical methods, chemical methods, gas atomization methods, centrifugal atomization methods, metal thermal reduction methods, electrolytic methods, and the like. The metal powder produced by the rotating electrode method in the centrifugal atomization method is spherical, dense in structure, and narrow in particle size distribution. The parts used in 3D printing have high relative density and good mechanical properties. It is the main production method of metal powder for 3D printing at present. . [0003] The processing technology for producing metal powder by the rotating electrode method is to place the metal rod in an atomization chamber filled with inert gas, such as argon, helium, etc.,...
