Embodiment Construction
[0017] The present invention will be described in detail below in combination with specific embodiments.
[0018] The method for manufacturing the air deformation nozzle by 3D printing of the present invention is implemented according to the following steps:
[0019] Step 1. Process the micropowder materials used for printing
[0020] 1.1) The material selected for the preparation nozzle is TaC+Ni micropowder, the ratio of TaC to Ni is 1: 5%-15%, and the particle size of the micropowder is 0.5-10μm. The two are called metal-based ceramic micropowder together. Add ethylene glycol to the powder for wetting;
[0021] TaC micropowder has the characteristics of wear resistance, high hardness, high melting point, high corrosion resistance, and oxidation resistance. In order to reduce the sintering temperature in the subsequent process, Ni micropowder is doped into TaC micropowder, using TaC micropowder as the skeleton material, and Ni micropowder As a doping material to build stre...

Abstract
The invention discloses a method for manufacturing an air texturing nozzle by 3D printing. The method comprises the following steps: step 1, performing treatment on a micro powder material used for printing: selecting metal-based ceramic ultrafine powder of TaC and Ni, adding ethylene glycol into the metal-based ceramic ultrafine powder for wetting, adding a silane coupling agent into the wetted metal-based ceramic ultrafine powder, and performing ball milling on the mixture in a ball mill; step 2, printing the air texturing nozzle: establishing a 3D model of the printing object, namely the air texturing nozzle, exporting the model in the STL format, performing slicing and layering on the 3D model of the air texturing nozzle, and importing the STL format data of a workpiece to be molded into the 3D printing equipment; setting parameters, performing layering on the metal-based ceramic ultrafine powder, and performing laser scanning sinter molding; step 3, performing surface treatment on the printed air texturing nozzle to obtain the air texturing nozzle finished product. The method provided by the invention is reasonable in design and high in manufacturing precision.
Description
technical field [0001] The invention belongs to the technical field of 3D printing of mechanical parts, and in particular relates to a method for manufacturing air deformation nozzles by 3D printing. Background technique [0002] The air texturing nozzle is a key component in the production of air texturized yarn. As the core component of the air texturing machine used in the textile industry, it has a decisive impact on the quality and productivity of air texturized yarn (ATY) products. Because the nozzle relies on compressed air to generate eddy currents to deform the chemical fibers and produce different textures, the surface roughness value is required to be small. Since the air deforming nozzle is subjected to continuous impact and friction of high-speed air flow and the processed filaments and particles in the air during work, the most common and common failure mode of the air deforming nozzle is excessive wear, and due to the There is a small amount or a small amount...
