Description
Technical field
It the utility model is related to water injector, more particularly to a kind of pressure spray for uniformly being sprayed water to plane
Head.
Background technology
When for example large-scale plate of metalwork is heat-treated, first metalwork is needed to be cooled to normal temperature after rolling or directly quenched
Fire obtains required product or semi-finished product, in cooling procedure, in order to ensure that the mechanical performance of large-scale plate requires to want during cooling
Uniformly, constant speed and rapidly plate is cooled；But existing workpiece heat and cooling procedure in, due to top layer and center portion
Cooling velocity and inconsistent, the formation temperature difference of time, may result in volumetric expansion and shrink uneven and produce thermal stress, answered in heat
In the presence of power, because top layer start temperature is less than center portion, shrinks also greater than center portion and make center portion tension, when cool down is complete,
Because center portion finally cools down, volume contraction can not freely carry out and make top layer compression center portion tension, and this phenomenon is cooled speed
The influence of the factors such as degree, material composition and Technology for Heating Processing, when cooling velocity is faster, phosphorus content and alloying component are higher, cooling
During thermal stress effect under it is caused it is uneven plastic deformation it is bigger, the residual stress eventually formed is just bigger；The opposing party
Face workpiece in heat treatment process because the change of tissue is austenite to during martensite transfor mation, because the increase of specific volume can be with work
The expansion of part volume, each position priority phase transformation of workpiece, volume length is caused to make great difference and produce structural stress.Structural stress changes
Final result be top layer tension stress, center portion compression chord, just with thermal stress on the contrary, thus to quench cooling velocity be one
Quenching quality can be influenceed and an important factor for determine residual stress, and one hardening flaw can be given it is important or even decisive
The factor of influence.In order to reach the purpose of quenching, it is often necessary to accelerate cooling velocity of the part in high temperature section, and past
The critical hardening cooling velocity of workpiece can just obtain martensitic structure.And existing cooling water injector, due to the high pressure of ejection
Water column skewness, the cooling velocity in the same section of workpiece is caused to differ, so that position different on the same section of workpiece
Stress is different, and caused deformation is different, causes workpiece to deform.
Utility model content
The purpose of this utility model is to provide a kind of pressure spray head, is highly suitable for uniformly spraying water to plane.
According to one side of the present utility model, there is provided a kind of pressure spray for uniformly being sprayed water to plane
Head, including main jet face and side spray face, main jet face are plane, and the angle between side spray face and main jet face is 45 °, and side spray face is located at master
Spray plane both sides, main jet face are provided with main burner, and side spray face is provided with side nozzle.
In some embodiments, main burner is straight type nozzle.
In some embodiments, side nozzle is shrinkage type nozzle.
In some embodiments, side nozzle includes water inlet, delivery port and located at transition part between the two, water inlet
Mouthful it is more than the internal diameter of delivery port located at water spray side, the internal diameter of water inlet located at water inlet side, delivery port.
In some embodiments, the internal diameter of water inlet is 2~3 times of internal diameter of delivery port.
In some embodiments, main burner and side nozzle are perpendicular with main jet face and side spray face respectively.
In some embodiments, the cross section of water inlet and delivery port is circle.
Using above technical scheme for the pressure spray head uniformly sprayed water to plane, structure to nozzle and set
Angle setting degree is all optimized, it is possible thereby to spray pressure stability and the water jets under high pressure being evenly distributed to plane.Applied
When in quenching bed, water jets under high pressure can be made uniformly to be quenched to workpiece, make the cooling velocity in the same section of workpiece identical, from
And making position stress different on the same section of workpiece, caused deformation is also identical, so as to reach more preferable quenching effect.
