Problems solved by technology

However, this type of nozzle cannot scan and swing during the atomization process, so scanning atomization cannot be performed. Therefore, the deposition area is small, and it is not suitable for preparing wider metal slabs, larger diameter tube blanks and larger diameter metal cylinder blank

Embodiment 1

[0018] Such as Figure 4 As shown, the restrictive scanning gas atomization system of the present invention is composed of a restrictive atomizing nozzle 31, a flow guiding mechanism 41 and a scanning swing mechanism 21. The flow guiding mechanism 41 is located in the middle of the restrictive atomizing nozzle 31, and the restrictive atomizing nozzle 31 is a non-restricted atomizing nozzle structure, which is connected with the scanning swing mechanism 21 through a connecting piece to realize the swing scanning of the restrictive atomizing nozzle 31 in the atomization process; The central axis coincides.

[0019] The lower end of the restrictive atomizing nozzle 31 has 36 vent holes 31A (the vent holes 31A in this embodiment are ring hole structures) evenly distributed on the circumference of its lower end, and the outer wall of the restrictive atomizing nozzle 31 has atomizing gas introduction holes 31B; The introduction hole 31B is connected to the atomizing gas pipeline th...

Abstract

The present invention relates to a restrictive scanning gas-atomizing system. It is formed from gas-atomizing nozzle, guide mechanism and scanning-swinging mechanism. Said guide mechanism is positioned in the centre of gas-atomizing nozzle, said gas-atomizing nozzle is connected with scanning-swinging mechanism by means of connecting component, and the axis of the described guide mechanism is coincided with the axis of said gas-atomizing nozzle. Said invention can improve atomizing effect, and can raise the quality of spray-formed blank, and can be used for spray-forming wide-width plate blank, pipe blank and rod blank.

Description

technical field [0001] The invention belongs to the technical field of gas atomization, in particular to a restricted scanning gas atomization system for metal injection molding equipment. Background technique [0002] In the metal spray forming process, high-pressure gas atomizes a continuous stream of metal liquid through atomizing nozzles, breaking it into tiny droplets. The droplets are then cooled and deposited to form a metal blank. This process is a typical rapid solidification process. The design of the atomizing nozzle is very important. A good atomizing nozzle should have a high gas atomization efficiency and ensure a high cooling rate of the atomized liquid droplets. In addition, in order to prepare larger slabs, tube blanks and cylindrical blanks, it is often required that the nozzle can scan and swing during the atomization process. [0003] At present, according to the different ways of cooperation between the metal liquid guide tube and the atomizing nozzle...
