Description
Technical field
The utility model relates to a kind of induction heating spraying quenching device, belongs to the machinofacture heat treatment technics.
Background technology
The hard surfacing of workpiece such as the roller of prior art, axle class is handled, generally all be that employing induction heater and cooling fluid spraying quenching device are arranged apart, and be bound up before and after making induction heater and cooling fluid spraying quenching device by mechanism, and synchronously along the technical scheme of processed workpiece axial motion.Undoubtedly, this prior art exists structure more complicated, preparation cost than higher, the cumbersome deficiency that waits of maintenance.
Summary of the invention
The purpose of this utility model is to provide a kind of induction heating spraying quenching device that induction heater and cooling fluid spraying quenching device are integrated into one, and overcoming the structure more complicated of prior art, preparation cost is than higher, maintenance is cumbersome wait not enough.
The technical scheme that realizes the purpose of this utility model is, a kind of induction heating spraying quenching device, has the induction heating ring, its improvement is: induction heating ring system open tube induction heating ring, bead position under open tube induction heating ring inboard and along its circumferential direction, be provided with and the axis of open tube induction heating ring between have cooling fluid jet hole, cooling fluid liquid-inlet pipe and the fixedly connected and mutual perforation of open tube induction heating ring of angle α.
Can understand that by above given technical scheme the utility model is integrated into one induction heating ring and cooling fluid spraying quenching device.That is to say, when being done turning motion by the workpiece of quench treatment, the utility model by the linear velocity of setting along by the axial motion of quench treatment workpiece the time, heated by the energising of induction heating ring earlier by the quench treatment workpiece, the cooling fluid that the back is imported by the cooling fluid liquid-inlet pipe, through open tube induction heating endless tube inner chamber, again by being located at the cooling fluid jet hole ejection at the inboard bead of open tube induction heating ring position, and implement to spray the processing of quenching, thereby finish by the quench treatment of quench treatment workpiece to reaching the above workpiece of AC3 temperature (quenching temperature).So also just realized the purpose of this utility model.
Further improvement of the utility model point also is:
The cooling fluid liquid-inlet pipe has 2 at least.This is in order to make the cooling fluid that enters open tube induction heater inner chamber have enough capacity, and order is along the spray volume basically identical of the set cooling fluid that each jet hole sprayed of open tube induction heating ring circumferential direction.About this point, it is for bigger being even more important by the quench treatment of quench treatment workpiece in cross section.Do like this, can under the existence condition of a plurality of cooling fluid liquid-inlet pipes, ensure by the consistence of the quenching hardness of quench treatment workpiece.
The cross section of open tube induction heating ring can be round, or oval, or the side.And the cross section of the open tube induction heating ring of the utility model special recommendation is rectangular.And make the long limit of the rectangular open tube induction heating ring of cross section get close to by the quench treatment workpiece surface.Obviously, the purpose of doing like this is, improves by the heating surface area of quench treatment workpiece, thereby improves the speed that is heated up by the quench treatment workpiece.
At the beneath bead position of the rectangular open tube induction heating ring inboard of cross section and be provided with along its circumferential direction domatic, cooling fluid jet hole and domatic being orthogonal.Be provided with domatic purpose, be for said domatic on, can arrange multiple tracks cooling fluid jet hole along its circumferential direction.Do like this,, improve by the quenching quality of quench treatment workpiece because the existence of multiple tracks cooling fluid jet hole can be accelerated by the speed of cooling of quench treatment workpiece.
The cooling fluid jet hole is along domatic width, divides at least to be set as 2 rows and by spacing L
1Uniform distribution; Cooling fluid jet hole set on each row is by spacing L
2Along the circumferential direction uniform distribution; L
1≤ 3mm, L
2≤ 6mm.Obviously, the cooling fluid jet hole of intensive layout like this for improving by the speed of cooling of quench treatment workpiece with owing to can accelerate movement velocity of the present utility model, and improves the quench treatment working efficiency, all is very favourable.
Existing angle α is 30 °～60 ° between cooling fluid jet hole and the open tube induction heating ring axis.The utility model has been made repetition test in its R﹠D process, angle α is best between 30 °～60 °.Test-results is declared publicly, and angle α＞60 ° can be caused the cooling fluid splash to by on the hot face of quench treatment workpiece, and be formed by quench treatment workpiece local heating deficiency, produce the quality problems of quench " soft spots ".And angle α＜30 °, then cooling fluid can be injected into again and leave by quench treatment workpiece hot face position far away, and directly has influence on by the quenching hardness requirement of quench treatment workpiece.
The cooling fluid jet hole is a circular hole, and the aperture is φ 1～3mm.Obviously, the cooling fluid jet hole is a circular hole, and not only complete processing is simple and easy for this, and because said jet hole is being equal under the area, circular hole is compared with the hole of other shape, the girth minimum of circular hole.This influence for the magnetoresistive effect of induction heater is also minimum, is good for the thermo-efficiency that improves induction heater.And the aperture of jet hole is set between φ 1～3mm, and this is to be decided by the amount of jet hole ejection according to cooling fluid.The quench treatment or the bigger workpiece of the quench treatment degree of depth of big workpiece can be selected big jet hole aperture, otherwise and can select little jet hole aperture.
By the coolant pressure that the cooling fluid spray hole sprayed be 〉=0.15MPa.In fact, the size of coolant pressure is mainly set by the quality of the cooling fluid that is adopted and the size in jet hole aperture.Bigger for cooling fluid employing tap water or jet hole aperture, its coolant pressure is just passable at 0.15MPa.Have the less such as emulsified water cooling fluid etc. or jet hole aperture of certain viscosity and adopt for cooling fluid, the pressure of its cooling fluid then will be suitable just now more than 0.2MPa.
Characteristics such as after above-mentioned the technical solution of the utility model was implemented, what it had was simple in structure, and preparation cost is lower, and maintenance is convenient are conspicuous, and also have by advantages such as the quench treatment quality are good.
