Description
Technical field
The present invention relates to a kind of device of the sleeve part for eddy-current heating knife rest.
Particularly for the cutter rotated with higher rotation speed, such as milling cutter and drill bit are it is known that their shank shrink-fit is in the sleeve part of knife rest.This sleeve part such as heats by means of the induction coil around this sleeve part for this reason, expands, in the receiving mouth namely expanded so that the described tool shank inserting described sleeve part is subject to heat affecting.The external diameter of this knife rest is slightly larger than the nominal diameter of this receiving mouth, thus cutter rotationally fixedly after described sleeve part cooling is press-fitted in knife rest.
Background technology
Such as DE 101 02 710 A1 provides a kind of induction heating apparatus being applicable to this.This device to have on a sleeve part that can be sleeved on knife rest and surrounds the induction coil of this sleeve part at this moment circlewise with certain radial spacing, to this induction coil supply alternating current.The magnetic field of described induction coil knife rest conduct electricity, in most magnetizable material induction produce induced-current, the direct heating muff portion of this induced-current.This induction coil axially extends to and at least exceedes tool shank and stretch into and receive the bonding length in mouth and roughly concordant with described sleeve part vertically in the scope of the end face of the cutter side of sleeve part with its winding.Diametrically, the internal circumference of induction coil and sleeve part keep certain distance ground to distribute, identical induction coil can be used in the knife rest with different sleeve part external diameters.
The winding of described induction coil on its side and on its excircle by one by magnetizable, i.e. electromagnetic flux field concentrator (Flusskonzentrator) adjusting device that forms of ferromagnet or ferrimagnet material, magnetic flux focuses on shell by magnetic property that described material is high relative to air substantially.The described magnetizable material of this electromagnetic flux field concentrator adjusting device is nonconducting, to avoid making the also sensed heating of this electromagnetic flux field concentrator shell.The scope adjacent with the end face of the cutter side of sleeve part of described electromagnetic flux field concentrator shell is designed to main ringwise concentrated body, and this concentrated body directly axially abuts on the end of sleeve part cutter side.Meaning and the object of concentrated body are like this, magnetic field is on purpose imported in sleeve part, can effectively play a role there to make it, and prevent from the outstanding tool shank sensed heating by stray field component of sleeve part simultaneously, tool shank also can expand thus, and this is undesirable.Advantageously, this concentrated body is designed to shield flange, such as, as described in DE 101 02 710 A1.First the interception of this shield flange spills into the major part of the field line in space outerpace.This shield flange also prevents the tool shank stretched out from being heated thus in an efficient way with method.
Even so, by aforementioned such device, in the external environment condition of induction coil and whole device, still there is the stray field that can survey, in most application scenario, this stray field does not have important impact to shrinking the major function loaded and take out.
In the recent period, outside all the time concerned especially proprietary field, increasing concern is occurred for theme " electric leakage field (elektrische Streufelder) ".
Summary of the invention
The object of the invention is the magnetic field reduced further in the external environment condition of induction coil and device.
This object is realized by the feature of claim 1 characteristic.Described concentrated body carries inductance boss indirectly or directly, and this inductance boss is made up of that conduct electricity and preferred non-magnetic material.This inductance boss produces and has magnetic field, this magnetic field is superimposed with the magnetic field being distributed in the induction coil in the external environment condition of induction coil and device, and partly makes this field weakening thus.By this way and method, with by by the non-conductive and material of magnetic conduction, the pole shoe made as ferrite realizes and the shielding that therefore can be described as " passive screening (passive Abschirmung) " is compared, and achieves one (being generally additional) magnetic field shielding initiatively.
Regulation according to claim 2, described inductance boss by the section of one-tenth (partly) part in magnetic field that distributes outside described concentrated body pass like this, that is, at the internal induction generation current of described inductance boss own.In brief, the magnetic field of weakening in the external environment condition of described coil automatically guarantees to produce the opposing magnetic field of carrying out abated effect from described inductance boss.
Preferably, described inductance boss is designed to the ring of along the circumferential direction self-closing usually.This inductance boss ensure that best shielding by this way with method, because the field line of high frequency magnetic field is is also intercepted and captured thus veritably completely, and can not produce reaction to the effect of inductance boss of the present invention.
Particularly preferably be the configuration of the inductance boss be made of copper.Because verified, particularly in application scenario of the present invention, copper can obtain the action effect of the equivalent material (such as aluminium) of looking significantly more than other.
Described inductance boss is preferably designed to the cross section of the ring making it have crimping.Described inductance boss radially exceedes described concentrator from described concentrated body thus and extends along outside direction, and, by regulation install concentrate body to make it have horizontal orientation time, from described concentrated body with one relative to horizontal direction slightly tilt (preferably 10 degree to 20 degree) upwards extend.By this way and method, described inductance boss constitutes for the described otherwise major part with the field line of the tendency of first enclosure aggregate body and a kind ofly hinders structure, and this obstruction structure is passed by described field line effectively.Namely described field line obtains effective utilization, to produce vortex flow and produce corresponding opposing magnetic field thus in described inductance boss.
Preferably design, described concentrated body inserts in a retaining ring at its radial outside.This retaining ring is used for positioning concentrated body relative to described magnetic coil arrangement.Simultaneously described retaining ring also makes described inductance boss be held in place relative to described concentrated body, preferably holds it in described concentrated body and the described inductance boss position that contacts of direct surface each other.Heat can flow in described concentrated body from described inductance boss with suitable degree rapidly thus.Also simplified the operation by this design, because this concentrated body and being fixed to one another all the time with the inductance boss that it matches is connected, and can one reinstate and changed to the corresponding component that the inductance boss that it matches form by another concentrated body and another if desired, and which inductance boss user must not consider this with which concentrated body match.In addition, if described concentrated body and described inductance boss surface contact each other, just ensure that the interaction of effective especially magnetic between concentrated body and inductance boss, namely guarantee the region realizing continuous print strengthening shielding.
In the scope of another preferred improvement project, described retaining ring is designed to plastic hoop.Such fact is take into account the most simply by means of plastic hoop, namely the relative motion produced by thermal expansion between described concentrated body and described inductance boss, this is almost inevitable, because different from concentrated body, inductance boss is directly heated due to the vortex flow produced therein.
Described retaining ring can certainly be designed to ceramic ring in principle.That is, when this ceramic ring is with certain gap enclosure aggregate body and inductance boss, this ceramic ring can not due to the thermal expansion of this concentrated body or this inductance boss and distending.But consider this point, the retaining ring be made up of pottery obviously more easily causes processing and tolerance issues compared with the clearly preferred retaining ring be made up of plastics.
If retaining ring is plastic hoop, manufacture the component be made up of inductance boss, concentrated body and plastic hoop ideally like this, that is, concentrated body is put into corresponding injection molding machine of plastic together with inductance boss, and utilize the plastics solidifying to form retaining ring to carry out encirclement injection to it.
Described retaining ring is by under heat-resisting, preferably more than 120 DEG C temperature conditions, and the plastics ideally up to 150 DEG C of deformation resistant are made, then can guarantee that it keeps function.Manufacture the retaining ring be made up of heat-resisting plastics to make it possible to interruptedly sequentially not carry out multiple contraction loading or fetch cycle, and following situation can not be there is, namely be heated to the degree of the plastics making its heat damage retaining ring by least inductance boss, make by inductance boss, the component failure of concentrating body and plastic hoop to form.As the plastics considering for above-mentioned application purpose to adopt, PI can be enumerated especially or also have PTFE plastics.
In the scope of a particularly preferred form of implementation, the plastics of described retaining ring completely or partially surround inductance boss, and especially also surround in such region of its excircle, when user takes out the component be made up of inductance boss, concentrated body and plastic hoop from device, described region may be touched unintentionally.By this way and method, avoid such danger, that is, due to the good heat conductive surface of inductance boss described in user direct contact, user is surprisingly burnt on the inductance boss of heating.
Ideally, be provided with the contact protection portion be made of plastics of interruption at least partly for inductance boss or covered by it.The part that the contact protection portion of this interruption is normally made up of heat resistant plastice (such as above described plastics or nylon material), this part is provided with multiple port with spacing closely, is namely " interruption (unterbrochen) ".Realize directly arriving the metal surface of described inductance boss for (blow or convection current flow into) air of cooling or cooling medium by these ports, although there is contact protection portion also effectively can cool this inductance boss thus.Although closely interval is arranged, but each port is so little relative to the contact pin between port, even if when grasping the inductance boss being heated to about 80 DEG C, the skin of user also directly can not contact with the metal surface of this inductance boss through described port substantially, and is burnt due to the strong heat conductivility on surface at this moment.Because depend on concrete condition, cannot illustrate, port is necessary in particular situations and much and manyly closely separates.But those skilled in the art can be tested several times by minority for definite concrete condition and determine above-mentioned situation when considering following provisions; namely usually should hinder entering of the air on described inductance boss metal surface and cold medium as small as possible, thus described metal surface should be covered in the necessary degree in fixing contact protection portion.Described contact protection portion can be designed to the integral part of described retaining ring or be designed to independent component.It is desirable that the contact protection portion of described interruption is designed to the closed cage (Kaefig) of one at least segmentation (locally).Namely be designed to such cage, this cage under any circumstance all partly with the surface contact of described inductance boss, and its " grid section (Gitterabschnitt) " is spaced apart with the surface of described inductance boss significantly.In addition, described contact protection portion also can directly abut on the surface of described inductance boss, such as, in mode that is netted or grid.
Ideally, described inductance boss is designed to make it have so large thermal capacity and quality, be less than 100 DEG C to make the final temperature of this inductance boss after the contraction cycle repeatedly directly in succession carried out each other and be preferably less than 80 DEG C, in described contraction cycle, respectively a colder knife rest is heated to such degree, that is, associated cutter can be loaded and again therefrom take out.This is important, because the electric current by responding to generation here in described inductance boss produces larger heat, described heat can only export in extraneous air around at short notice deficiently.However, described inductance body does not allow any heating.This can be made up by described mode.

Detailed description of the invention
Before inductance boss of the present invention is described in detail, first generally the function of Fig. 1 shown device is described.
Can see, this knife rest 1 is made by least conducting electricity, going back the material such as steel of magnetic conduction here.This knife rest has sleeve part 2 on its other end.This sleeve part 2 comprises the receiving mouth 4 that is centrally aligned to the rotation 3 of this knife rest, can load the rotary cutter be not shown specifically in this receiving mouth 4 for one with its shank 5, such as drill bit, milling cutter or also have milling cutter.
The external diameter of this shank 5 is slightly larger than the free nominal diameter receiving mouth 4, thus shank 5 remains in sleeve part 2 by press-fit, thus can by required transmission of torque on rotary cutter.In order to be enclosed in by tool shank 5 in knife rest 1 or from wherein taking out, by heating, sleeve part 2 is expanded.Described heating be by means of in a set of sleeved portion 2 and the induction coil 6 surrounding the case surface of this sleeve part with certain radial spacing with one heart carry out.Can utilize frequency be such as 5 to 20kHz alternating current or pulse direct current described induction coil is powered.The magnetic flux produced by the winding 7 of near cylindrical produces vortex flow at sleeve part 2 internal induction.Described vortex flow is heating muff portion 2 in the shorter time, and makes receiving mouth 4 fully expand further thus, can insert or take out tool shank.
Induction coil 6 has the coil case 8 be made up of heat-resisting plastics or pottery be provided at its inner portion, and is arranged on this coil case by the winding 7 of multilayer.The excircle of winding 7 and axially dorsad cutter end face by one or multi-piece type, by magnetic conduction and the yoke adjusting device 9 that electrically non-conductive material is made cover, this material is by the magnetic flux boundling in the environmental field of winding 7 and converge on yoke adjusting device 9.
This winding 7 being provided with yoke adjusting device 9 is being defined as the whole length of receiving mouth 4 or sleeve part 2 for receiving tool shank 5 extends substantially.
In order to magnetic flux is led towards the end face 10 of sleeve part 2 slightly above the outstanding yoke adjusting device 9 of winding 7 vertically best from this side; and shielding tool shank 5 exceedes the outstanding part of sleeve part 2 simultaneously; and protect its not sensed heating; arrange one to coil end face SF and concentrate body 11, this concentrated body controls from yoke adjusting device 9 magnetic field out.As shown in Figure 1, this concentrated body 11 is preferably designed to the form of shield flange.This concentrated body is made up of the permeability magnetic material can assembling magnetic flux, and certain described material is nonconducting substantially, and therefore under the impact in magnetic field, it can not obviously be heated.
The concentrated body 11 of formation like this distributes spaced at a distance in each side and yoke adjusting device 9.In illustrated embodiment, yoke adjusting device 9 does not extend beyond the end face of the cutter side of winding 7, but only slightly protrudes from this end face, but can also cover coil where necessary.Concentrated body has the flat contact surface 12 of a distribution perpendicular to axial direction vertically towards sleeve part 2, utilize this contact surface, and described concentrated body can abut on the end face here for annular of sleeve part 2 on surface.
Concentrate body 11 to be provided with a retaining ring 13, this retaining ring is by resistance to higher temperatures temperature, not magnetic conduction and non electrically conductive material is made, and is particularly made of plastics.By this retaining ring 13, body 11 is concentrated to fix relative to induction coil 6, but fixing like this, namely can select to replace this concentrator by the one of the slightly different concentrated body (not shown) of size if desired.By this way, body 11 is concentrated to guarantee the correct axial location of sleeve part 2 relative to induction coil 6 of (knife rest) corresponding loading.In addition, this concentrated body can also be changed in order to make identical induction coil 6 match from the knife rest with different sleeve parts 2.
Although the annular gap reserved between yoke adjusting device 9 and the concentrated body 11 being designed to shield flange shape here improves the impedance in the magnetic circuit of induction coil 6; But concentrate body 11 to allow to be focused on sleeve part 2 by magnetic flux magnetic leakage free with higher degree in tool shank 5 scope as the design of shield flange due to it.By this way, this sleeve part 2 can sensedly heat, and there will not be the superheated to tool shank 5.
The present invention's concentrated body 11 here arranges an inductance boss 14 on the outside of its induction coil 6 dorsad.Different from concentrated body, this inductance boss by good conductive but non-magnetic material make.
Inductance boss 14 directly contacts with concentrated body 11 here in large area.Inductance boss and concentrated body are substantially along concentrating the whole upper plane of body to contact.By this way, inductance boss 14 can when needed quickly by the Energy transmission that produces wherein on concentrated body, prevent possible overheated of inductance boss thus.
This inductance boss 14 radially exceedes concentrated body and tilts to stretch out.Now it be preferably inclined upwardly distribution (show greatly relative to horizontal direction 10 to 20 spend angle α), as illustrated in fig. 1 and 2.Therefore this inductance boss 14 can be interpreted as with the annulus of upwards turnup on its excircle.This annulus outwards exceedes the flange that concentrated body stretches out by this way with method formation one.This flange forms a kind of blocking structure that must be passed by the major part of field line, described field line otherwise have such tendency, namely first walks around described concentrated body and only just enters concentrated body from the region higher apart from axis 3.
For this reason, in inductance boss 14, form vortex flow, described vortex flow itself forms a magnetic field certainly, a kind of opposing magnetic field.Therefore, the opposing magnetic field forming abated effect by inductance boss 14 is guaranteed in the magnetic field of the weakening in coil 9 external environment condition automatically.
This inductance boss is designed to a copper ring closed in a circumferential direction here.But in principle, also can adopt such as a kind of configuration being designed to aluminium ring here.But verified, the configuration as copper ring makes inductance boss have obvious more efficiently effect for the application scenario existed, cause the heating obviously less to inductance boss in other words here.
Concentrate body and inductance boss insert above cutline, in common retaining ring 13.Retaining ring 13 is made up of the plastics of the highly heat-resistant be injected on concentrated body 11 and inductance boss 14.The plastics of retaining ring the scope of its maximum outside diameter surround inductance boss and prevent user in this position directly with expose, hot and that the there is good heat conductive characteristic surface contact of inductance boss 14.
Fig. 3 shows the half sectional view of another embodiment of the present invention.
This embodiment is with the difference part of the embodiment before according to Fig. 1 and 2, here not that inductance boss is set itself to concentrated body 11, but direct-on-line coil apparatus 9 or solenoid housing (especially on the region of coil 6 towards sleeve part end end face) are provided with the inductance body 14a that is designed to flanged type here equally.Only otherwise relate to the above-mentioned specific features not have the inductance boss occurred in figure 3, described in above, (Fig. 1 and 2's) form of implementation is here also reasonably suitable for.
The operation principle of inductance body 14a with above for identical with the situation described in the inductance body of inductance boss 14 form, this inductance body 14a is passed by the magnetic field of coil 6, responds to generation current wherein thus.This electric current produces an opposing magnetic field, and this magnetic field part ground weakens main field or makes it turn to, thus also can realize initiatively shielding here.
Just be also pointed out that the footing portion F of the main part H keeping inductance body 14a, be not preferably be made up of the identical conduction of the main part H with flange-shape and non-magnetic material, but be preferably made up of plastic material.Thus, compared with the situation of the footing portion F be made up of conductive material, the thermic load of this inductance body can obviously be reduced.
Have nothing to do with concentrated body, first the fixing and maintenance of inductance body has significant practical significance for the system with adjustable coil and/or adjustable concentrated body, need not reequip described system in order to the shrink-fit for different sleeve diameter and change described coil or concentrated body.
In addition can determine, such as, also can act on similar active shielding element in the circumferentially installation of coil, such as, so that the operated key of shielded coil.
The inductance boss that finally be also pointed out that type described here of course not only be designed to shield flange concentrated body acting in conjunction competence exertion its act on.
