Description
Technical field
The present invention relates to a kind of device that is used for the sleeve part of eddy-current heating knife rest.
Particularly for the cutter with the higher rotation speed rotation, for example milling cutter and drill bit are known that their shank shrink-fit arrives in the sleeve part of knife rest.This sleeve part for example heats by means of the induction coil around this sleeve part for this reason, is subjected to heat affecting and expands with the described tool shank that will insert described sleeve part, promptly in the admittance mouth of Kuo Daing.The external diameter of this knife rest is slightly larger than the nominal diameter of this admittance mouth, thereby cutter is force-fitted in the knife rest at described sleeve part cooling back rotationally fixedly.
Background technology
For example DE 101 02 710 A1 provide a kind of induction heating apparatus that is applicable to this.This device has one and can be sleeved on the sleeve part of knife rest and surround the induction coil of this sleeve part at this moment with certain radial spacing circlewise, gives this induction coil supply alternating current.The magnetic field of described induction coil knife rest conduction, induction produces induced-current, the direct heating muff of this induced-current portion in most magnetizable materials.This induction coil extends axially at least and to surpass tool shank and stretch into bonding length in admitting mouthful 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 inner circumferential of induction coil and sleeve part keep certain distance ground to distribute, so that identical induction coil can be used in the knife rest with different sleeve part external diameters.
The winding of described induction coil on it is distolateral and on its excircle by one by magnetizable, be electromagnetic flux field concentrator (Flusskonzentrator) adjusting device that ferromagnet or ferrimagnet material are formed, the magnetic property that described material is high with respect to air focuses on magnetic flux on the shell basically.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 adjacent scope of end face described electromagnetic flux field concentrator shell and cutter side sleeve part is designed to main ringwise concentrated body, and this concentrated body directly axially abuts on the end of sleeve part cutter side.The meaning and the purpose of concentrated body like this are, on purpose import magnetic field in the sleeve part, so that it can play a role there effectively, and prevent simultaneously from the outstanding tool shank sensed heating of sleeve part by the stray field component, tool shank also can expand thus, and this is undesirable.Advantageously, this concentrated body is designed to shield flange, for example, and described in DE 101 02 710 A1.This shield flange interception at first spills into the major part of the field line in the space outerpace.This shield flange also prevents that with effective and efficient manner and method the tool shank that stretches out is heated thus.
Even so, in by aforementioned such device, still have the stray field that can survey in the external environment condition of induction coil and whole device, this stray field is packed into to contraction and the major function of taking out does not have significant effects in most application scenarios.
In the recent period, outside the proprietary field of all the time being paid close attention to especially, increasing concern has appearred in " electric leakage (elektrische Streufelder) " for theme.
Summary of the invention
The objective of the invention is further to reduce the magnetic field in the external environment condition of induction coil and device.
This purpose realizes by the feature of claim 1 characteristic.Described concentrated body carries the inductance boss indirectly or directly, and this inductance boss is made by the preferred non-magnetic material that reaches of conduction.Producing on this inductance boss has magnetic field, and the magnetic field of the induction coil in this magnetic field and the external environment condition that is distributed in induction coil and device is superimposed, and partly makes this field weakening thus.By this way and method, with the material that passes through by non-conductive and magnetic conduction, compare as the pole shoe shielding that realize and that therefore can be described as " passive screening (passive Abschirmung) " that ferrite is made, realized a kind of (being generally additional) magnetic field shielding initiatively.
According to the regulation of claim 2, described inductance boss is passed like this by a part that becomes the magnetic field outside the described concentrated body of section ground (partly) distribution,, produces electric current at the internal induction of described inductance boss own that is.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 self-closing along the circumferential direction usually.This inductance boss has been guaranteed best shielding with method by this way, because the field line of high frequency magnetic field also intercepted and captured thus veritably fully, and can not produce reaction to the effect of inductance boss of the present invention.
Particularly preferably be the configuration of the inductance boss that is made of copper.Because verified, in the application scenario particularly of the present invention, copper can obtain obviously to surpass the action effect that other looks the material (for example aluminium) of equivalence.
Described inductance boss is preferably designed to and makes it have the cross section of the ring of crimping.Described inductance boss radially surpasses described concentrator from described concentrated body thus and extends along outside direction, and, install to concentrate body in accordance with regulations so that it when having horizontal orientation, extends upward with respect to horizontal direction slight inclination (preferably spending to 20 degree 10) from described concentrated body with one.By this way and method, described inductance boss is for described otherwise have at first that the major part of the field line of the tendency of enclosure aggregate body has constituted a kind of obstruction structure, and this obstruction structure is passed by described field line effectively.Be that described field line has obtained effective utilization, in described inductance boss, to produce vortex flow and to produce corresponding opposing magnetic field thus.
Preferably design, described concentrated body is in its radial outside inserts a retaining ring.This retaining ring is used for positioning concentrating body with respect to described magnetic coil arrangement.Described retaining ring also makes described inductance boss be held in place with respect to described concentrated body simultaneously, preferably holds it in described concentrated body and described inductance boss direct surface position contacting each other.Heat can flow in the described concentrated body from described inductance boss with suitable degree apace thus.Also simplify the operation by this design, because should concentrate body and the inductance boss that is complementary is fixed to one another all the time is connected with it, and in case of necessity can one reinstate the corresponding member of forming by another concentrated body and another inductance boss that is complementary with it and change, and which inductance boss the user must not consider this with which concentrated body match.In addition,, just guaranteed concentrating the especially effectively interaction of magnetic between body and the inductance boss, promptly guaranteed to realize the zone of continuous reinforcement shielding if described concentrated body contacts on the surface each other with described inductance boss.
In the scope of another preferred improvement project, described retaining ring is designed to plastic hoop.Considered such fact the most simply by means of plastic hoop, the i.e. relative motion that between described concentrated body and described inductance boss, produces by thermal expansion, this almost is inevitable, because different with concentrated body, the inductance boss directly is heated owing to the vortex flow of portion's generation within it.
Described in principle retaining ring can certainly be designed to ceramic ring.That is to say, when this ceramic ring during with certain clearance enclosure aggregate body and inductance boss, this ceramic ring can be owing to the thermal expansion of this concentrated body or this inductance boss distending.But consider this point, compare obviously easier processing and the tolerance issues of causing with the clear and definite retaining ring of preferably forming by plastics by the retaining ring that pottery is made.
If retaining ring is a plastic hoop, make the member of forming by inductance boss, concentrated body and plastic hoop ideally like this, that is, will concentrate body and inductance boss to put into corresponding injection molding machine of plastic together, and utilize the plastics that solidify to form retaining ring that it is surrounded injection.
Described retaining ring by heat-resisting, preferably under the temperature conditions more than 120 ℃, make up to the plastics of 150 ℃ of anti-distortion ideally, can guarantee that then it keeps function.The retaining ring that manufacturing is made by heat-resisting plastics makes that can interruptedly not carry out a plurality of contractions in proper order packs into or the fetch cycle, and following situation can not take place, promptly be heated to the degree of the plastics that make its heat damage retaining ring, make by inductance boss, the component failure of concentrating body and plastic hoop to form by inductance boss at least.Consider the plastics that adopt as being used for above-mentioned application purpose, can enumerate PI especially or also have the PTFE plastics.
In the scope of a particularly preferred form of implementation, the plastics of described retaining ring completely or partially surround the inductance boss, and especially also in such zone of its excircle, surround, when the user takes out the member of being made up of inductance boss, concentrated body and plastic hoop from device, may touch described zone unintentionally.By this way and method, avoided such danger, that is, because the good heat conductive surface of the described inductance boss of user direct contact, the user is burnt by accident on the inductance boss of heating.
Ideally, be provided with the contact protection portion that is made of plastics of interruption at least partly for the inductance boss or by its covering.The part that the contact protection portion of this interruption is normally made by heat resistant plastice (for example above described plastics or nylon material), this part is provided with a plurality of ports with spacing closely, promptly is " (unterbrochen) of interruption ".The metal surface that (blow or convection current flow into) air that is used to cool off by these ports or cooling medium realize directly arriving described inductance boss is although there is contact protection portion also can cool off this inductance boss effectively thus.Although closely arrange at interval, but each port is all so little with respect to the contact pin between the port, even grasping when being heated to about 80 ℃ inductance boss, user's skin can not pass described port basically yet and directly contact with the metal surface of this inductance boss, and is burnt owing to the strong heat conductivility on surface at this moment.Because depend on concrete condition, can't specify, port is necessary for much under concrete condition and how closely separates.But those skilled in the art can test several times by minority at definite concrete condition and consider definite above-mentioned situation under the situation of following provisions; promptly should hinder entering of air on the described inductance boss metal surface and cold medium usually as small as possible, thereby should fixedly cover described metal surface on the necessary degree of contact protection portion.Described contact protection portion can be designed to the integral part of described retaining ring or be designed to independent member.It is desirable to, the contact protection portion of described interruption is designed to the closed cage (Kaefig) of a kind of segmentation at least (part).Promptly be designed to such cage, this cage under any circumstance all contacts with the surface of described inductance boss partly, and its " grid section (Gitterabschnitt) " is spaced apart on the surface with described inductance boss significantly.In addition, described contact protection portion also can directly abut on the surface of described inductance boss, for example in the mode of netted or grid.
Ideally, described inductance boss is designed so that it has so big thermal capacity and quality, so that the final temperature of this inductance boss after the contraction cycle that repeatedly directly carries out in succession each other is less than 100 ℃ and preferably less than 80 ℃, in described contraction cycle, respectively a colder knife rest is heated to such degree, that is can pack into associated cutter and therefrom taking out again.This is important, because the electric current that produces by induction here in described inductance boss produces bigger heat, described heat can only be exported in around the extraneous air at short notice deficiently.However, described inductance body does not allow any heating.This can be remedied with described mode.

The specific embodiment
Before inductance boss of the present invention was elaborated, the function to device shown in Figure 1 described at first generally.
Can see, this knife rest 1 by conduction at least, go back magnetic conduction here material for example steel make.This knife rest has sleeve part 2 on its other end.This sleeve part 2 comprises an admittance mouth 4 that is centrally aligned to the rotation 3 of this knife rest, is used for the rotary cutter that can pack into and not be shown specifically in this admittance mouthfuls 4 with its shank 5, for example drill bit, milling cutter or also have milling cutter.
The external diameter of this shank 5 is slightly larger than the free nominal diameter of admitting mouth 4, thereby shank 5 remains in the sleeve part 2 by interference fit, thus can be with required transmission of torque to rotary cutter.In order tool shank 5 to be enclosed in the knife rest 1 or, to make sleeve part 2 expansions by heating from wherein taking out.Described heating be by means of on the suit sleeve part 2 and the induction coil 6 that surrounds the case surface of this sleeve part with certain radial spacing with one heart carry out.Can utilize frequency is that for example 5 to 20kHz alternating current or pulse direct current are powered to described induction coil.The magnetic flux that winding 7 by near cylindrical produces produces vortex flow at sleeve part 2 internal inductions.Described vortex flow is heating muff portion 2 in the short time, and further makes admittance mouthful 4 fully expansions thus, so that can insert or take out tool shank.
This winding 7 that is provided with yoke adjusting device 9 extends on the whole length of the admittance mouth 4 that is defined as being used to admitting tool shank 5 or sleeve part 2 basically.
For with magnetic flux from this side, slightly surpassing winding 7 outstanding yoke adjusting devices 9 vertically best towards end face 10 guiding of sleeve part 2; and shield tool shank 5 simultaneously and surpass the outstanding part of sleeve part 2; and protect its not sensed heating; set one for coil end face SF and concentrate body 11, this concentrated body is controlled from the magnetic field that yoke adjusting device 9 comes out.As shown in Figure 1, this concentrated body 11 is preferably designed to the form of shield flange.Should concentrate body to be made by the permeability magnetic material that can assemble magnetic flux, certain described material is nonconducting basically, and therefore it can obviously not heated under the influence in magnetic field.
So the concentrated body 11 that constitutes distributes in each side and yoke adjusting device 9 spaced apartly.In the illustrated embodiment, yoke adjusting device 9 does not extend beyond the end face of the cutter side of winding 7, but only slightly protrudes in this end face, but can also cover coil where necessary.Concentrated body has the flat contact-making surface 12 of a distribution perpendicular to axial direction vertically towards sleeve part 2, utilize this contact-making surface, and described concentrated body can abut on the end face for annular here of sleeve part 2 on the surface.
Concentrate body 11 to be provided with a retaining ring 13, this retaining ring is by anti-higher temperatures temperature, magnetic conduction and non electrically conductive material are not made, and particularly is made of plastics.By this retaining ring 13, concentrate body 11 fixing with respect to induction coil 6, but fixing like this, promptly can replace this concentrator with a kind of selection of the slightly different concentrated body (not shown) of size in case of necessity.By this way, concentrate body 11 to guarantee the correct axial location of (knife rest) corresponding sleeve part of packing into 2 with respect to induction coil 6.In addition, can also be for identical induction coil 6 being complementary with the knife rest with different sleeve part 2 and changing this concentrated body.
Though improved impedance in the magnetic circuit of induction coil 6 at yoke adjusting device 9 and the annular gap that is designed to reserve between the concentrated body 11 of shield flange shape here; But concentrate body 11 owing to its design as shield flange allow in tool shank 5 scopes with higher degree with the magnetic flux magnetic leakage free focus on the sleeve part 2.By this way, this sleeve part 2 can sensedly heat, and the superheated to tool shank 5 can not occur.
The present invention's concentrated body 11 here is provided with an inductance boss 14 on the outside of induction coil 6 dorsad at it.Different with concentrated body, this inductance boss by good conductive but non-magnetic material make.
This inductance boss 14 radially outwards surpasses concentrates body to tilt to stretch out.Its distributions (showing the angle α that spends with respect to horizontal direction 10 to 20 greatly) that preferably be inclined upwardly this moment, as illustrated in fig. 1 and 2.Therefore this inductance boss 14 can be interpreted as annulus with the turnup that makes progress on its excircle.This annulus forms one with method by this way and outwards surpasses the flange of concentrating body to stretch out.This flange constitutes a kind of blocking structure that must be passed by the major part of field line, and described field line otherwise have such tendency is promptly at first walked around described concentrated body and had only from distance axis 3 higher zones and just enters concentrated body.
For this reason, form vortex flow in inductance boss 14, described vortex flow itself forms a magnetic field, a kind of opposing magnetic field certainly.Therefore, guarantee automatically to be set out by inductance boss 14 and form the opposing magnetic field of abated effect in the magnetic field of the weakening in coil 9 external environment conditions.
This inductance boss is designed to a closed in a circumferential direction copper ring here.But in principle, also can adopt for example a kind of configuration that is designed to the aluminium ring here.But verified, make inductance boss have obvious more efficiently effect as the configuration of copper ring for the application scenario that exists here, cause in other words the obviously littler heating of inductance boss.
Concentrate body and inductance boss insert above in cutline, the common retaining ring 13.Retaining ring 13 concentrates the plastics of the highly heat-resistant on body 11 and the inductance boss 14 to make by being injected at.The plastics of retaining ring surround the inductance boss and prevent that the user from directly contacting with the surface with having the good heat conductive characteristic that expose, heat of inductance boss 14 in this position in the scope of its maximum outside diameter.
Fig. 3 shows the half sectional view of another embodiment of the present invention.
This embodiment be according to the difference part of the described embodiment of Fig. 1 and 2 before, here not the inductance boss to be set itself, but be provided with an inductance body 14a who is designed to flanged type here equally on direct-on-line coil apparatus 9 or the solenoid housing (especially at coil 6 towards on the zone of sleeve part end end face) to concentrated body 11.Only otherwise relate to the above-mentioned concrete feature that does not appear at the inductance boss among Fig. 3, described (Fig. 1 and 2's) form of implementation here also reasonably is suitable for above.
The operation principle of inductance body 14a is with top identical at the described situation of inductance body with inductance boss 14 forms, and this inductance body 14a is passed by the magnetic field of coil 6, and induction produces electric current therein thus.This electric current produces an opposing magnetic field, and this magnetic field part ground weakens main field or it is turned to, thereby also can realize initiatively shielding here.
Just be also pointed out that the F of footing portion of the main part H that keeps inductance body 14a, be not to make preferably, but preferably make by plastic material by conduction identical and non-magnetic material with the main part H of flange-shape.Thus, compare, can obviously reduce the thermic load of this inductance body with the situation of the F of footing portion that makes by conductive material.
Irrelevant with concentrated body, inductance body fixing and keep at first having significant practical significance for the system with adjustable coil and/or adjustable concentrated body needn't be changed described coil or concentrated body in order to reequip described system at the shrink-fit of different sleeve diameters.
Can determine in addition, for example also can be on the circumference of coil the similar shielding element initiatively of installation effect, for example so that the operated key of shielded coil.
The inductance boss that be also pointed out that type described here at last of course not only with its effect of concentrated body acting in conjunction competence exertion that is designed to shield flange.
