Description

Notch quenching inducer

Technical field

This utility model relates to thermal processing tool field, particularly relates to a kind of notch quenching inducer.

Background technology

In the manufacture process of auto parts, usually need to use quenching inducer that the surface of part is quenched, piece surface is made to have the characteristic of high-hardness, wearable degree, the core of part keeps again good intensity, toughness and plasticity simultaneously, and the part after heat treatment has wear-resistant and resisting fatigue characteristic.

Magnetic field can be formed on conventional quenching inducer and this magnetic field is directly used in the conductor of heated parts is referred to as active conductor, conventional active conductor is the most ring-type, part is integrally placed in active conductor and heats, then the piece surface water spray after heating is quenched, but for having the part of notch on some outer surfaces, conventional quenching inducer will appear from heating uneven phenomenon at notch so that the slot-open-section quenching effect of part is unsatisfactory；Further, for part as such in the shift rug in automobile gearbox, two sides of the allocating slot on shift rug need to quench, and conventional quenching inducer is due to the restriction of its contour structures, it is impossible to put it in notch the side to notch and quench.

Utility model content

This utility model is intended to provide a kind of notch quenching inducer, uniformly to heat the notch of part and to quench.

Notch quenching inducer in this programme, including active conductor and water jet, wherein the sectional dimension of active conductor is less than 15mm × 15mm, active conductor is four copper pipes being parallel to each other, four copper pipes are fixed on one piece of copper coin jointly, four copper pipes are positioned at copper coin the same side, and on every two copper pipes, there is an electrode plate common connection, has two electrode plate；Being provided with sparge pipe between four copper pipes, sparge pipe is communicated to described water jet, and sparge pipe has spray orifice.

The know-why of this programme and have the beneficial effect that the notch of quenching will be needed to ride over outside active conductor, each side of notch is all relative with active conductor, and the bottom surface of notch is relative with spray orifice, certain interval is kept between notch and active conductor, two electrode plate are connected to alternating current power supply, passing to the alternating current of 5KHz-500KHz, the alternating current in active conductor produces faradic current on notch, thus causes notch to generate heat.Owing to each side of notch is all relative with active conductor, active conductor can make each side of notch be inductively heated, and therefore heats evenly.After notch is heated to uniform temperature, the cooling water of water jet ejection high pressure, high pressure cooling water is ejected towards the bottom surface of notch, and flows out from the gap between notch side and active conductor, each face of notch, during flowing, is quenched by high pressure cooling water.Owing to the overall dimensions of notch is the least, in order to ride on active conductor by notch, the overall dimensions of active conductor can not be too big, therefore must control the sectional dimension of active conductor at 15mm × below 15mm.

Prioritization scheme one based on such scheme: described copper pipe is copper tube.Copper tube electrical efficiency is high, produces faradic effect more preferable.

Prioritization scheme two based on prioritization scheme one: described copper tube is square tube.The side of square tube is plane, compared with conventional arc surface, plane and notch relative to time, the effective area that sensing occurs is bigger.

Being filled with silicon steel magnetic conductor in the space surrounded between three: four described copper pipes of prioritization scheme based on prioritization scheme two, silicon steel magnetic conductor is enclosed within outside described sparge pipe, and silicon steel magnetic conductor has conduction hole, and conduction hole connects with described spray orifice.Silicon steel magnetic conductor magnetic flux rate is high, can increase the magnetic field intensity of active conductor, and the magnetic field of active conductor is the strongest, and the efficiency of sensing heating is the highest.

Prioritization scheme four based on prioritization scheme three: described sparge pipe is tungsten alloy pipe.When active conductor carries out sensing heating to notch, the temperature of sparge pipe also can increase, and in order to avoid sparge pipe melts, sparge pipe uses the tungsten alloy pipe that fusing point is higher.

Detailed description of the invention

Below by detailed description of the invention, this utility model is described in further detail:

Reference in Figure of description includes: active conductor 1, water jet 2, red copper square tube 3, copper coin 4, battery lead plate 5, sparge pipe 6, spray orifice 7, silicon steel magnetic conductor 8, conduction hole 9, notch 10, bottom surface 101, side 102, part 11.

Embodiment notch quenching inducer is the most as shown in Figure 1: include active conductor 1 and water jet 2, wherein the sectional dimension of active conductor 1 is less than 15mm × 15mm, active conductor 1 is four red copper square tubes 3 being parallel to each other, four red copper square tubes 3 are fixed on one piece of copper coin 4 jointly, four red copper square tubes 3 are positioned at copper coin 4 the same side, on every two copper pipes, there is an electrode plate 5 common connection, has two electrode plate 5；Being provided with sparge pipe 6 between four copper pipes, sparge pipe 6 is communicated to described water jet 2, and sparge pipe 6 has spray orifice 7；Being filled with silicon steel magnetic conductor 8 in the space surrounded between four described red copper square tubes 3, silicon steel magnetic conductor 8 is enclosed within outside described sparge pipe 6, and silicon steel magnetic conductor 8 has conduction hole 9, and conduction hole 9 connects with described spray orifice 7；Sparge pipe 6 is tungsten alloy pipe.

Active conductor 1 forms a column, and the side 102 of active conductor 1 is a plane.Its sectional view is as shown in Figure 2.

nullDuring actually used，The notch 10 needing quenching is ridden over outside active conductor 1，Each side 102 of notch 10 is all relative with active conductor 1，And the bottom surface 101 of notch 10 is relative with spray orifice 7，The gap of 3mm is kept between notch 10 and active conductor 1，Two electrode plate 5 are connected to alternating current power supply，Pass to the alternating current of 5KHz-500KHz，Alternating current in active conductor 1 produces faradic current on notch 10，Thus cause notch 10 to generate heat，When notch 10 be heated to quench temperature required after，Water jet 2 sprays the cooling water of high pressure，High pressure cooling water is ejected towards the bottom surface 101 of notch 10 after the spray orifice 7 on sparge pipe 6 and the conduction hole 9 on silicon steel magnetic conductor 8，First the bottom surface 101 of notch 10 is quenched，High-pressure cooling water is under the driving of pressure，Flow out from the gap between notch 10 side 102 and active conductor 1，Again the side 102 of notch 10 is quenched during flowing.Owing to the overall dimensions of notch 10 is the least, in order to ride on active conductor 1 by notch 10, the overall dimensions of active conductor 1 can not be too big, and therefore the sectional dimension of active conductor 1 is 10mm × 10mm.

Owing to active conductor 1 is relatively thin, the most easily melting, therefore during using, the sprinkling of high-pressure cooling water needs in time, otherwise to easily cause active conductor 1 and fuse and damage.

Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
