Abstract

The invention discloses a method for processing a spinning cup by using Al-Cu-Mn-Mg hard aluminum alloy as a material, belonging to the technical field of spinning machineries. The spinning cup is processed by the following steps of preparing a blank through injection molding; normalizing; heavy boring; induction hardening, carrying out chemical treatment on surface; depositing; and coating on surface. The spinning cup prepared by the method is easy to process, is of a more reasonable structure, has long service life, good wear resistance, mechanical property, sealing performance, corrosion resistance and oxidation resistance, does not overflow lubricating grease, prevents rubber rollers and cotton silver from being contaminated, further meets the lubricating requirement of a bearing, further prolongs the service life of the bearing, and is applicable to high speed and low speed spinning machineries.

Description

technical field [0001] The invention belongs to the field of textile machinery and relates to a rotor and a hard aluminum alloy thereof. In particular, it is a processing and forming manufacturing process for a rotor made of Al-Cu-Mn-Mg hard aluminum alloy. Background technique [0002] With the continuous development of rotor spinning technology, people have deepened the research on the key parts and materials of rotor spinning. This is because in the production practice of rotor spinning, people have gradually realized that the wear of key parts will It will seriously affect the spinning quality, end breakage and production efficiency. The rotor used in air spinning in textile machinery is the conical component that collects fibers, condenses, merges, and twists into yarn in rotor spinning. The rotating speed of the spinning cup is very high, its centrifugal force is relatively large, and the negative pressure inside the spinning cup is very high, so the air resistance su...
