Problems solved by technology

The disadvantage of existing vacuum degreasing and sintering furnaces is that degreasing cannot be completed at one time, and the degreasing rate at one time is low, that is, in addition to the first degreasing of lipids that are extracted through the degreasing pipeline, a second degreasing is often required, that is, the furnace body is opened and the furnace body is degreased again. Degreasing cleaning, complex operation, low processing efficiency

Abstract

The invention relates to a method for metal powder vacuum sintering forming. The method for metal powder vacuum sintering forming comprises the following steps in sequence: (1) material loading: putting a metal powder product to be processed in a hearth of a vacuum degreasing sintering furnace; (2) vacuumizing: carrying out vacuumizing treatment on the hearth of the vacuum degreasing sintering furnace; (3) degreasing: clearing a forming agent in the metal powder product; (4) high temperature sintering. The method for metal powder vacuum sintering forming has the advantages of novel technology, convenient degreasing and high primary degreasing rate.

Description

technical field [0001] The invention relates to the field of vacuum heat treatment equipment, in particular to a vacuum degreasing sintering furnace for metal powder injection molding. Background technique [0002] Vacuum degreasing sintering furnace is a vacuum heat treatment equipment with vacuum degreasing and vacuum sintering functions, which is widely used in metal powder injection molding production. The structure of the existing vacuum degreasing sintering furnace mainly includes a furnace body provided with a degreasing pipeline and a degreasing box arranged in the furnace body. An incubator is arranged in the furnace body, and the pre-degreased product is placed in the degreasing box for heating. The degreasing port is drawn out through the degreasing pipeline, which can avoid the furnace body from being polluted by lipids. When cleaning, only the degreasing box needs to be cleaned. The lipids in the product are mainly forming agents. The disadvantage of existing v...
