It is not used to limit the enforceable scope of the present invention, its relativeness is altered or modified, in the case where changing technology contents without essence, when
Also it is considered as the enforceable category of the present invention.
As shown in Figures 1 to 3, the present invention provides a kind of reducing type spray quenching apparatus, including support body 4 and is arranged on support body 4
On multiple spraying mechanisms, spraying mechanism includes drive system, the connecting rod 2 of spray piping 5 and at least two, and spray piping 5 is along perpendicular
Nogata is to setting, and all connecting rods 2 be arranged in parallel and one end and the outer wall of spray piping 5 are hinged, the other end and the phase of support body 4
Be hinged, multiple spray pipings 5, which are uniformly distributed along the circumference, surrounds a spray chamber that can house workpiece 11 to be quenched, spray piping 5
Inside be provided with multiple closed subregions on vertically, the closed subregion on each spray piping 5 on sustained height is logical
Cross flexible pipe 3 to connect on same liquor charging pipeline, be provided with the tube wall of each closed subregion multiple towards workpiece 11 to be quenched
Nozzle 7；Drive system includes linear drive apparatus, drawstring 103 and fixed pulley 102, and linear drive apparatus and fixed pulley 102 are equal
Be arranged on the top of spray piping 5, one end of drawstring 103 is connected with the mobile terminal spindle nose of linear drive apparatus, the other end around
It is connected after crossing fixed pulley 102 with connecting rod 2.
Multiple spray pipings 5 being vertically arranged in the present invention surround an adjustable spray cavity, in initial position
When spray piping 5 due to conduct oneself with dignity it is sagging, now spray cavity for maximum, according to the maximum outside diameter of workpiece 11 to be quenched adjust set
Linear drive apparatus at top, the mobile terminal spindle nose of linear drive apparatus is set to retract, the drawstring 103 being connected on spindle nose will even
The up pull-up of bar 2, now the central side of spray piping 5 to spray cavity move, spray cavity be contracted to it is suitably sized, with hanging
Holding tool hangs in workpiece 11 to be quenched in the spray chamber body adjusted, and is rotated under lifting device effect, according to be quenched
The quenching technical requirement of 11 axially different position of workpiece, adjusts the pressure and flow in corresponding liquor charging pipeline, so as to control phase
Quenching hydraulic coupling and flow in corresponding closed subregion, required to reach the different quenchings at axially different position.
Patent of the present invention can adjust the radial dimension of spray cavity, meet that the quenching of different-diameter rotor axial workpiece will
Ask, while the present invention can also be directed to the different diameter adjustment spray pipings 5 of workpiece to be quenched 11 to most suitable position, can be more
The distance of nozzle 7 and axle body, reaches more preferable quenching effect, is quenched to adapt to the difference of diverse location when being accurately controlled quenching

Vertical interval between adjacent circulating line 6 is one meter.When workpiece 11 to be quenched hangs in spray cavity, first make workpiece upper end and spray
The upper end of pipeline 5 is concordant, so distance can be with the naked eye estimated according to the interval of circulating line 6, so that it is determined that going out to be quenched
Circulating line 6 corresponding to the axially different position of workpiece 11, can more intuitively be judged, convenient and swift.
The quantity of spraying mechanism does not limit in principle in the present invention, but the spraying mechanism of the present embodiment is 12, and
Centered on the rotating shaft of circulating line 6, circumferentially shape array is arranged on support body 4, so can both ensure there are enough through hardening
Property, it will not increase machine utilization because of excessive again.
The bottom of the support body 4 of the present embodiment is provided with cistern 9, and draining pump 8 is provided with cistern 9.Row can be passed through
Water pump 8 takes the hydrops in cistern 9 away in time, prevents hydrops from flooding workpiece 11 to be quenched, influences quenching property.
The reducing type spray quenching apparatus of the present embodiment, which also includes being arranged on outside whole reducing type spray quenching apparatus, to be used
In the wall 10 for preventing current splashing and thermal insulation.
Control valve is additionally provided with the liquor charging pipeline of the present embodiment, can be controlled in liquor charging pipeline and quenched by control valve
The pressure and flow of fiery liquid, and therein several, energy-saving and emission-reduction can be closed when the diameter of workpiece 11 to be quenched is smaller.
All linear drive apparatus are by same PLC coordinated signals in the present embodiment.Can be by PLC to straight
Line drive device coordinates control.
Linear drive apparatus in the present invention can be hydraulic jack or cylinder, but be hydraulic oil used by the present embodiment
Cylinder 101.
In summary, the present invention can adjust the radial dimension of spray cavity, meet different-diameter rotor axial workpiece
Quenching requires, while the present invention can also be directed to different diameter of work to be quenched and adjust spray piping to most suitable position,
The distance of delivery port and axle body during energy more precise control quenching, reaches more preferable quenching effect.It can solve the problem that in the prior art
The spray cavity size of sprinkling equipment can not adjust, it is impossible to the problem of being quenched to the workpiece to be quenched of different-diameter.So
