Answer device.
Background technology
Induced surface hardening is the principle using electromagnetic induction, makes part cutting magnetic line in alternating magnetic field,
Surface generates sensing electric current, and according to alternating current kelvin effect, quickly heated piece surface with eddy currents, then chilling
Process for quenching.Now the flank of tooth of driving wheel is carried out induction hardening to be all is quenched by what is be connected with AC power every time
Fiery inductor quenches after carrying out sensing heating to the single flank of tooth of driving wheel, and such repetitive operation reduces operating personnel indirectly
Working efficiency.
Utility model content
The purpose of this utility model is to provide a kind of novel drive wheel flank of tooth quenching inducer, is quenched with solving the existing flank of tooth
The problem of quenching efficiency present in fiery inductor is relatively low.
The utility model is realized in this way：
A kind of novel drive wheel flank of tooth quenching inducer, including induction coil, the induction coil by hollow copper tubing in the shape of a spiral
It crimps, the both ends of the hollow copper tubing are hatch frame, and the entirety of the induction coil is cylindrical in shape structure, the induction coil
The number of turn for multiturn, set and have the gap between every circle hollow copper tubing of the induction coil and the hollow copper tubing of adjacent turn, the sense
The internal diameter that should be enclosed is bigger 50mm ~ 70mm than driving wheel tooth top diameter of a circle to be quenched, and the one end open of the hollow copper tubing is provided with
Cooling water inlet, another end opening are provided with cooling water outlet.
The hollow copper tubing is square copper pipe.
The number of turn of the induction coil is the circle of 6 circles ~ 9.
The internal diameter of the induction coil is bigger 60mm than driving wheel tooth top diameter of a circle to be quenched.
The cooling water inlet is arranged on the opening positioned at induction coil bottom of the hollow copper tubing, and the cooling water goes out
Mouth is arranged on the opening being located at the top of induction coil of the hollow copper tubing.
The axial length of the induction coil entirety is 200mm.
The utility model includes induction coil, and induction coil is crimped in the shape of a spiral by hollow copper tubing, the both ends of hollow copper tubing
It is hatch frame, the entirety of induction coil is cylindrical in shape structure, and the number of turn of induction coil is multiturn, is overcome on single turn quenching inducer
The problem of electric current easily deviates, can effectively improve the heating rate of the sliding tooth flank of tooth, and be less than the temperature of drive gear hub portion
The temperature of face portion reduces the hardness of hub portion after quenching in this way, improves the production efficiency of mechanical processing, and subtracts
The loss of process tool is lacked.When the flank of tooth to sliding tooth quenches, after sliding tooth sensing heating to design temperature, operator
Member rotates sliding tooth itself and is moved downwardly until into quenching press to carry out flank of tooth quenching.
The utility model is simple in structure and cost of investment is relatively low, can effectively improve driving wheel quenching efficiency, and being capable of basis
The quenching hardness of adjusting control driving wheel is needed, improves the driving wheel integral hardness occurred during former resistance furnace integral heating quenching
Quality problems really up to the mark or excessively soft, improve product quality.In addition, the utility model can share a power supply with quenching machine,
Reduce the cost of equipment.

Specific embodiment
As depicted in figs. 1 and 2, the utility model include induction coil 1, induction coil 1 crimped in the shape of a spiral by hollow copper tubing and
Into hollow copper tubing is square copper pipe.In the present embodiment, the cross section of hollow copper tubing is rectangle, outside the cross section of hollow copper tubing
The length on edge is 25mm, is highly 20mm, and the height of thickness 5mm, i.e. induction coil 1 per circle hollow copper tubing is 20mm, radially-wide
It spends for 25mm.The both ends of hollow copper tubing are hatch frame, and the entirety of induction coil 1 is cylindrical in shape structure, i.e. every circle of induction coil 1 is empty
Corresponding outer edge is concordant with adjacent turn hollow copper tubing for the outer edge of heart copper pipe, the generally cylindrical structure of induction coil 1.Sensing
The whole axial length of circle 1 is 200mm.The number of turn of induction coil 1 is multiturn, in the present embodiment, the number of turn of induction coil 1 for 6 circles ~
9 circles.It sets and has the gap between every circle hollow copper tubing of induction coil 1 and the hollow copper tubing of adjacent turn, the internal diameter ratio of induction coil 1 is waited to quench
The fireflood driving wheel big 50mm ~ 70mm of tooth top diameter of a circle, in the present embodiment, the internal diameter of induction coil 1 is than driving wheel tooth top to be quenched
The big 60mm of diameter of a circle.The one end open of hollow copper tubing is provided with cooling water inlet 2, and another end opening is provided with cooling water and goes out
Mouth 3.Cooling water inlet 2 is arranged on the opening positioned at 1 bottom of induction coil of hollow copper tubing, and cooling water outlet 3 is arranged on hollow
The opening for being located at 1 top of induction coil of copper pipe, the cavity of hollow copper tubing is cooling chamber, is stopping the sensing heating to driving wheel
Afterwards, circulating water device is set between cooling water inlet 2 and cooling water outlet 3, induction coil can be cooled down, to extend sensing
The service life of circle.
When carrying out induction hardening processing to driving wheel using the utility model, by the central axis of driving wheel and sense
The central hub that should be enclosed overlaps, and driving wheel heats under rotation status at a slow speed, and 1 minute or so, the tooth socket and crown of driving wheel were opened
Beginning reddens, until at 3 minutes, tooth socket and crown temperature reach 850 DEG C ~ 900 DEG C of hardening heat, and about 400 DEG C of left sides of hub portion
It is right.This is off heating, and driving wheel rotation is carried out quenching treatment downwards and into quenching machine.The result shows that utilize this reality
High with the tooth socket of the driving wheel after novel induction hardening and the hardness of crown, hardness gradient is gradually dropped from crown to center
It is low.For hub portion because temperature is low, hardness is accordingly low, improves the machining efficiency of wheel hub instead.Due to new using this practicality
Control can be adjusted to heating time and heating power, therefore be not in phenomenon of rupture in type.
