Abstract

Provided are a vacuum water quenching system and a vacuum water quenching method of a bearing. The vacuum water quenching system is provided with a heating chamber, a cooling chamber, an external transfer basket and an external transfer trolley, wherein the heating chamber and the cooling chamber are partitioned in a sealed mode by a cooling chamber heat insulation door. A vacuumizing pipeline communicating with a vacuum pump unit is arranged in the heating chamber, and an inflation pipeline communicating with an oxygen-free inflation system is arranged in the cooling chamber. A quenching water tank is arranged in the cooling chamber. According to the vacuum water quenching method, a semi-finished bearing to be processed is conveyed into the cooling chamber, the vacuum environment is started, the semi-finished bearing is conveyed into the heating chamber for vacuum thermal processing, moisture removal is conducted on the cooling chamber and the heating chamber, and the bearing subjected to thermal processing is conveyed into the cooling chamber to be subjected to vacuum water quenching, lifted out of water and discharged.

Description

technical field [0001] The invention relates to metal processing technology, in particular to a vacuum water quenching system and a vacuum water quenching method for bearings. Background technique [0002] For a long time, bearing products have problems such as oil quenching is not hard, water quenching is easy to crack, and organic PAG is unstable for a long time. Inorganic water-based quenching medium and organic-inorganic composite water-based quenching medium can solve the above problems; but the quenching process of bearing rolling elements and rings There is also the problem of oxidative decarburization. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a vacuum water quenching method for bearings in a vacuum water quenching system, propose a vacuum quenching method for bearings based on water-based media, comprehensively improve the quality of bearing products, reduce deformation, and reduce subsequent proce...
