Description
Technical field
Heat treatment quenching process of the present invention vacuum hardening tank structure is related to one kind during heat treatment, to quenching
Oil groove carries out the stirring structure of internal temperature sum, belongs to heat treatment equipment field.In particular to a kind of to be carried out in main body case
Stirring, by mixing part in main body case can the offset of circumferentially rotatable, axial reciprocating, radial reciprocal opening and closing, quench
The oil-quenching tank of internal temperature equilibrium is realized in the stirring of kerosene.
Background technique
Currently, metal product is heat-treated in industrial processes, especially some engineering machinery
Components are heat-treated to reach certain material property, and in being heat-treated, the most common quenching process, usually
By metal material heating, heat preservation, the technique being quickly cooled down, has little time to grow by the crystal grain that chilling means are metal insides, mention
High material property, it usually needs cooled down using hardening media, generally use quenching oil, for large parts, in order to true
Complete through hardening is protected, needs to be placed on progress in oil groove, such as floating bearing seat etc., existing oil groove is all simple container, interior
Portion fills quenching oil, and when part is put into internal cooling, since temperature is higher, the temperature of quenching oil is sharply increased, each in oil groove
The temperature difference at place is big, can not carry out the flowing of quenching oil well, and quenching quality and efficiency is turned up, existing to pass through stirring
Device is stirred, and is rotated by single blade, in blade rotary course, is easy to get to metal product surface, and oil
Groove sidewall, safety is poor, and blade stirring is limited in scope, and also has and installs spray head in oil groove inner wall, is made by the fluid in spray head
With so that the quenching oil in oil groove is flowed, but the penetrating force of its injection is small, and the resistance in quenching oil is big, needs larger
