Description
Technical field
This utility model belongs to quenching apparatus technical field, more particularly, to a kind of quenching cooler.
Background technology
Quenching is important integral link in heat treatment step, and quenching is steel part to be heated to austenitizing temperature and keeps
After certain time, to cool down more than the speed of critical cooling rate, change tissue, such as martensite, shellfish to obtain non-diffusing type
The Technology for Heating Processing of family name's body and austenite etc..Workpiece in quenching cooling procedure, the rate of cooling of quenching cooling surface and center portion
There is different, if this species diversity is sufficiently large, is likely to result in and is partially converted to martensite more than critical cooling rate, and little
Center portion in critical cooling rate can not be transformed into the situation of martensite.For ensureing all to be changed into martensite needs in whole cross section
From the sufficiently strong cooling medium of cooling capacity, to ensure that workpiece center portion has sufficiently high rate of cooling；But rate of cooling is big,
Inside workpiece due to expand with heat and contract with cold uneven cause internal stress, workpiece deformation may be made or ftracture, thus above two to be considered
Contradictory factor, reasonable selection cooling medium and the type of cooling.
In prior art, the cooling pipe setting of chiller is more single, is generally only that the bottom to accessory die is carried out
Cooling treatment, causes accessory each several part rate of cooling inconsistent, and deforming easily occurs in product.For making workpiece quenching cooling procedure
Middle surface and center portion rate of cooling quite, make the media flow in quenching tank uniformly rationally it is ensured that part obtains after heat treatment
The hardness requiring and good mechanical performance, and deformation can be reduced and avoid problems of crack, there is provided a kind of quenching is cold
But device.
Utility model content
Surface is different with center portion rate of cooling can lead to steel in order to solve in workpiece quenching cooling procedure for this utility model
A kind of problem that the structure of part changes, there is provided quenching cooler.
In order to achieve the above object, base case of the present utility model provides a kind of quenching cooler, including quenching tank
And cooling tower, it is provided with feed tube between quenching tank upper end and cooling tower, between quenching tank lower end and cooling tower, be provided with liquid back pipe,

On output shaft, follower is fixed on the upper end of rot, and the lower end of rot is installed with shaft, and water jet is provided with band
The spray supervisor of nozzle, spray supervisor communicated with feed tube.
In this programme, the top of quenching tank is provided with circular water jet, and the center of water jet is provided with rot, this
Quenching tank cell body can be closed by sample, compared with traditional mixing pump, not there is a problem of sealing leakage and workpiece is difficult by oxygen
Change；The top position setting actuating device of rot, actuating device is located above quenching tank cell body, and actuating device drivewheel connects
Motor, driven pulley connects rot, and the rotation of such motor can drive rot to rotate by belt transmission, and belt
Actuating device make, easy to maintenance；The spray with nozzle for setting supervisor on water jet above quenching tank cell body, can be to processing
Part carries out uniform, quick cooling；The lower end of rot is provided with shaft, and the stirring of shaft can accelerate cooling in quenching tank
The circulation rate of medium；Filter on liquid back pipe can filter the coolant flowing out in quenching tank, will not bring impurity into
In cooling tower.
The principle of this base case is：In the operation that the workpiece in quenching tank is cooled down, first will be to be added
Workpiece is placed in quenching tank, open the circulation pump, and the coolant in cooling tower enters the spray supervisor in water jet by feed tube
In, by spraying the nozzle being responsible for, spray cooling is carried out to workpiece to be cooled, meanwhile, open motor, motor passes through to pass
Send the rot with driving under follower to rotate, the coolant of quenching trench bottom is stirred, accelerates the flowing of coolant, quench
The coolant of fiery trench bottom enters return duct under the suction of circulating pump, is filtered by the filter on return duct and enters cooling tower
In, after coolant cools down in cooling tower again, it is again introduced in feed tube, carry out next circulation.
The having the beneficial effects that of this base case：Because water jet is provided with multiple nozzles, and the stirring of rot lower end
Mix the flowing that axle also can further speed up coolant, the combination of the two can make the center portion of workpiece to be added and outside basic cooling speed
Degree quite, solves the surface structure that can lead to steel part different with center portion rate of cooling in workpiece quenching cooling procedure and becomes
The problem changed.
Scheme two：Based on this, scheme is preferred, spray supervisor be ring pipe, spray supervisor be provided with multigroup radially
And the spray arm with nozzle.Beneficial effect：Shower is provided with multigroup spray arm communicating with spray supervisor, and spray
Pipe is provided with multiple nozzles, and the coolant in such shower can separately flow in each spray arm, can be to be processed
Part carries out sufficiently cool.
Scheme three：This is the preferred of scheme two, and the nozzle on spray arm is uniformly distributed.Beneficial effect：So in motor
During driving shaft to rotate, because the nozzle on spray arm is uniformly distributed, can be by each position in quenching tank
Sprayed, if spray arm is very intensive, nozzle is distributed also than comparatively dense, whole cooling procedure is accomplished no dead substantially
Angle.
Scheme four：This is the preferred of scheme three, and feed tube is provided with circulating pump and filter.Beneficial effect：On feed tube
Circulating pump the coolant in cooling tower can be made to circulate, coolant in feed tube can be entered by the filter on feed tube
Row filters, when such coolant flows into the nozzle in water jet, will not plug nozzle.
Scheme five：This is the preferred of scheme four, and shaft is fixedly connected by flange coupling with rot.Beneficial effect
Really：Flange coupling rigidity is big, can transmit larger moment of torsion, in actual applications, has non-maintaining, superpower oil resistant and resistance to
The advantage of corrosion.
