Zusammenfassung:	Metal parts prevents oxidation treatment device includes: hollow barrel, this barrel supply to treat that refrigerated metal parts places wherein, first inflow pipeline communicates in the barrel for pour into inert gas into barrel, the first pipeline that effluents communicates in the barrel for take out inert gas from the barrel, be located the cooling intermediate layer of barrel wall portion, be full of the refrigerant in the cooling intermediate layer, second inflow pipeline for pour into the refrigerant into to the cooling intermediate layer, the second pipeline that effluents for to cool off the refrigerant that has absorbed the heat in the intermediate layer takes out from the barrel, the vacuum pipe, the one end of vacuum pipe communicates inside the barrel for take out from remaining the air in the barrel. The utility model discloses an isolated air utilizes inert gas to carry out gradual physics cooling as the mode of heat convection for casting fashioned accurate metal parts, reaches the purpose o
