Problems solved by technology

[0003] Since the main material of powder metallurgy is metal powder, and the raw material is decomposed into powder, the pulverizer needs to continuously crush the raw material, causing huge power consumption and noise pollution. In the process of powder loading into the mold cavity, a single mold cavity The amount of powder required is the same, but the amount of powder injected ...

Abstract

The invention discloses an energy-saving powder metallurgy process. The energy-saving powder metallurgy process includes steps of preparing, mixing, compacting, sintering, aging treatment, shaping and warehousing. According to the arrangement, powder materials are directly adopted without primary mashing and fed to a compacting die through a standard dosage barrel, thus high accuracy is achieved, compactness of part blanks is good, and pass percentage is high. Particularly, natural aging treatment is adopted to lead to low internal stress and remarkable energy saving after crystals are formed.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy technology, in particular to an energy-saving powder metallurgy technology. Background technique [0002] The powder metallurgy process mainly includes three steps. First, the main constituent materials are decomposed into powders composed of many fine particles; size of the compact; finally, the compact is sintered. [0003] Since the main material of powder metallurgy is metal powder, and the raw material is decomposed into powder, the pulverizer needs to continuously crush the raw material, causing huge power consumption and noise pollution. In the process of powder loading into the mold cavity, a single mold cavity The amount of powder required is the same, but the amount of powder injected into the mold cavity is often abnormal in the mass production of blanks. Too much powder is wasted as usual and the abnormality of the press is too small. The compact is not dense enough, and eve...
