Description
Technical field
The utility model belongs to the quenching cooler in a kind of thermal treatment, refers in particular to the quenching cooler for 42CrMo high-grade car tooth bar, gear heat treatment technique.
Background technology
Automobile steering device is developed to electrodynamictype by hydraulic power assisted, and tooth bar or gear are as the strength member of steering box, and its tissue, hardness and linearity require very harsh, are the difficult points of heat treatment process.Domesticly by traditional salt bath furnace, box-type furnace or common continuous type furnace, Tempering and Quenching is carried out to automobile steering device tooth bar, quenching mode adopts oil quenching or medium quenching usually, the tooth bar heart table difference of hardness of process is large, internal stress is large, yielding after processing, hydraulic power assisted sedan steering machine can only be used for, difficult for electric steering gear.
The accurate tooth bar blank of electric power steering machine mainly adopts continous way induction heating, can only adopt the heat treating method of water quenching.But to 42CrMo material, water quenching will make surface produce quenching crack, produce waste product.Must develop meet the demands can the continous way water quenching refrigerating unit of controlled cooling model speed, not only can meet performance requriements, but also can not surface crack be produced, and then replace oil quenching.
Summary of the invention
The utility model provides a kind of car rack pinion water quenching refrigerating unit, adopts water quenching that surface can be made to produce quenching crack, produce the problem of waste product to solve.
The technical scheme that the utility model is taked is, rollgang is provided with in water leg, water-supply line is positioned at the top of water leg, the centre of described rollgang is provided with 4 ~ 8 spray quenching devices, be connected with water-supply line by pipeline above this spray quenching device, the bottom of this spray quenching device is water spray ring, this water spray ring there is spray orifice, the front end of rollgang is V shaped wheel, this V shaped wheel is connected with variable frequency reducer motor output shaft, described water-supply line is provided with motor-driven control valve, magnetic flow meter, tensimeter and temperature sensor, and water-supply line is connected with working shaft.
The utility model spray orifice injection direction is tooth bar working direction, and angularly α.
The angle [alpha] of the utility model spray orifice is 30 ~ 60 degree.
The utility model has the advantages that novel structure, owing to adopting multiple spray quenching device, all standing can be accomplished at rack surface, realize tooth bar cooling uniformity, Reducing distortion amount, owing to adopting large discharge injection water quenching but, can realize the phase transformation of car tooth bar quenching structure, reach heat treatment performance requirement, cooling power is strong, and evenly, the 42CrMo car tooth bar quenching structure through quench treatment changes evenly in cooling, hardness is high, flawless, can meet the requirement of corresponding high-level standard.
