Process utilizing powder metallurgy to manufacture gear output shaft

Abstract

The invention discloses a process utilizing powder metallurgy to manufacture a gear output shaft. The process comprises performing stirring, forming sintering, turning machining, heat treatment, grinding with vibration, oil immersion and packaging on basic iron powder and other formula powder materials to obtain the gear output shaft. The process utilizing the powder metallurgy to manufacture the gear output shaft has the advantages that part deviation is formed in a forming step through a mould in a one-step mode, process steps are simplified, surface quality of products is improved, adverse impact of an original process is reduced, production raw materials are reduced, production efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention relates to a process for manufacturing a gear output shaft by powder metallurgy. Background technique [0002] At present, the process of manufacturing gear output shaft in powder metallurgy industry is mostly: stirring-forming-sintering-packaging. In this process, in order to reduce costs, many companies adopt methods such as streamlining the formula or reducing the process. Although the streamlined formula saves costs, it lacks guarantee for product performance and quality, and can only be used for some of the lowest-end products. Turning oil must be used for machining, which will easily lead to a layer of putty on the surface of the parts after heat treatment, which will affect the appearance. If it is to be removed, it must be brushed off, which will easily increase labor and increase costs. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the invention is to provide a simpl...

In this process, in order to reduce costs, many companies adopt methods such as streamlining the formula or reducing the process. Although the streamlined formula saves costs, it lacks guarantee for product performance and quality, and can only be used for some of the lowest-end products. Turning oil must be used for machining. It is easy to cause the surface of the parts to be covered with a layer of putty after heat treatment, which will affect the appearance. If you want to remove it, you must brush it off, which is easy to increase labor and increase the cost.
