Powder metallurgy component and production method of powder metallurgy component with mounting through hole

Abstract

The invention discloses a powder metallurgy component. The powder metallurgy component comprises, by weight, 100 parts of steel powder, 4-5 parts of copper powder, 1-2 parts of iron sulfide, 1-2 partsof rare earth powder, 1-2 parts of nickel powder, 3-5 parts of calcium fluoride, 0.1-0.3 part of micronized wax, 1.2-1.5 parts of molybdenum powder, 2-4 parts of a forming agent and 0.5-0.9 part of alubricating agent. According to the powder metallurgy component, alloy iron-based powder obtained by fully mixing the steel powder, the copper powder, the iron sulfide, the rare earth powder, the nickel powder, the calcium fluoride, the micronized wax, the molybdenum powder, the forming agent and the lubricating agent is subjected to pressing, sintering, machining, heat treatment and surface vibration grinding treatment, and then a finished product is obtained. Due to the fact that a powder metallurgy machining technology is adopted, the integrated degree is high, large-scale repeated production is facilitated, the surface smoothness is good, cutting machining is not needed, and the advantages of material saving, time saving and the like are achieved.

Description

technical field [0001] The invention relates to the field of powder metallurgy, in particular to a method for producing powder metallurgy parts and powder metallurgy parts with installation through holes. Background technique [0002] The so-called powder metallurgy parts refer to the finished products of various shapes by pressing the alloy iron-based mixed powder through the mold. At present, for powder metallurgy parts with mounting through holes, most of them still use traditional machining methods, which not only have complicated manufacturing procedures and high costs; but also the obtained finished products have low hardness and insufficient wear resistance, which greatly shortens the bevel gear. service life. Contents of the invention [0003] In order to achieve the above object, the present invention provides the following technical solution: a powder metallurgy part, which consists of the following components: iron and steel powder, copper powder, iron sulfide,...
