Description
Fremgangsmåte ved fremstilling av magnetkrets for elektromagnet. Procedure for manufacturing magnetic circuit for electromagnet.
Foreliggende oppfinnelse vedrbrer en fremgangsmåte ved fremstilling av laminerte magnetkjerner og ankere for elektro-magneter, særlig vekselstrbmmagneter som tjener som manbver-magneter f.eks. for lb ftemagneter, kontaktorer, reléer m.m. The present invention relates to a method for the production of laminated magnetic cores and anchors for electromagnets, in particular alternating current magnets which serve as manbever magnets, e.g. for lb fte magnets, contactors, relays, etc.
Hvis en vekselstrbmmagnet skal oppvise lave effekttap . og arbeide stille og vibrasjonsfritt, kreves godt anlegg mellom anker og kjerne. Dette har man hittil vanligvis oppnådd ved å gi kjernens og ankerets pol-flater den bnskede planhet ved skjærende bearbeidelse, f.eks. sliping. En sådan arbeidsoperasjon er imid-lertid relativt tidskrevende, hvilket har påvirket magnetens pris i ugunstig retning. If an alternating current magnet is to exhibit low power losses. and work quietly and without vibration, a good connection between the anchor and the core is required. Up until now, this has usually been achieved by giving the pole surfaces of the core and armature the desired flatness by cutting, e.g. grinding. However, such a work operation is relatively time-consuming, which has adversely affected the magnet's price.
I henhold til oppfinnelsen formes polflatene på magnet-kretsens deler (kjernen henholdsvis ankeret) ved at disse på i og for seg kjent måte av et antall sammenfbyede plateelemr.nter be-stående magnetkretsdeler hver for seg anbringes mellom to i forhold til hinannen bevegelige verktbydeler som deretter presses sammen i hovedsaken vinkelrett på mag netkretsdelens polflate. Denne over-flate utsettes på denne måte for et hbyt" trykk og undergår derved en plastisk deformasjon. Denne fremgangsmåte er i sammenligning med skjærende bearbeidelse hurtigere og mindre arbeidskrevende og fblgelig Skonomisk fordelaktig. Fremgangsmåten ha r -des suten den fordel at der ved koldbearbeide 1 sen av polflaten oppnås en bkning av dens mekaniske slitestyrke. Sistnevnte forhold er særlig viktig ved laminerte vekselstrbmmagneter for tung drift. Ved f.eks. kontaktorer, ved hvilke der kreves en mekanisk 1evetid på 15 - 20 millioner koblinger og koblefrekvenser av storre 1 sesordenen 3000 koblinger pr. time kan forekomme, er det selvsagt meget uheldig at manbvermagnetenes polflater deformeres etter en tids drift med de ovenfor anfbrte ulemper som folge. Undertiden oppviser magneter av denne art etter noen tid også utslåtte polflater, såkalt Kvas-ting. Denne tendens nedsettes som folge av den ifblge oppfinnelsen foreslåtte fremgangsmåte ved at magnetmaterialets hårdhet oker på grunnav koldbearbeidelsen. According to the invention, the pole surfaces of the magnetic circuit parts (the core and the armature respectively) are formed by placing these magnetic circuit parts consisting of a number of connected plate elements in a manner known per se between two relative movable tool parts which then pressed together mainly perpendicular to the pole surface of the mag network part. This surface is exposed in this way to a high pressure and thereby undergoes a plastic deformation. Compared to cutting, this method is faster and less labor-intensive and possibly economically advantageous. The method has the advantage that in cold working 1 of the pole surface, a reduction in its mechanical wear resistance is achieved. The latter condition is particularly important for laminated alternating current magnets for heavy duty. For example contactors, where a mechanical lifetime of 15 - 20 million connections and switching frequencies of the order of 3000 are required connections per hour can occur, it is of course very unfortunate that the pole surfaces of the manbever magnets are deformed after a period of operation, with the above-mentioned disadvantages as a consequence. Sometimes magnets of this type also exhibit worn-out pole surfaces after some time, so-called Kvas-ting. This tendency is described as consequence of the method proposed according to the invention in that the hardness of the magnetic material increases by g runnav cold working.
Den bnskede planhet av polflaten kan oppnås ved en eneste kraftig nedpressing eller ved flere mindre slag. I visse tilfelle kan det være fordelaktig at arbeidsoperasjonen utfores med vibrerende verktby således at pressbevege 1 sen henholdsvis slagene over-lagres med små vibrasjoner. The desired flatness of the pole surface can be achieved by a single forceful pressing down or by several smaller strokes. In certain cases, it can be advantageous for the work operation to be carried out with a vibrating tool so that the press movement 1 and the blows respectively are superimposed with small vibrations.
En vekselstrbmmagnet er vanligvis forsynt med en kort-sluttet ring (såkalt skjermvik1 ing) innlagt i spor i polflaten. Formålet med en sådan ring er å forbedre magnetens heldekraft. Ringen kan festes i sin stilling på forskjellige måter, såsom ved liming eller lodding. I forbindelse med en fremgangsmåte, ved hvilken polflatene formes ved plastisk bearbeidelse, har det dog vist seg å være meget fordelaktig også å la i prinsippet samme me-tode komme til anvendelse ved fiksering av skjermviklingen. Denne fiksering kan utfores for eller samtidig med at polflaten formes. An alternating current magnet is usually provided with a short-circuited ring (so-called screen winding) embedded in grooves in the pole surface. The purpose of such a ring is to improve the holding power of the magnet. The ring can be fixed in position in various ways, such as by gluing or soldering. In connection with a method in which the pole surfaces are shaped by plastic processing, it has, however, proven to be very advantageous to also allow the same method to be used in principle when fixing the screen winding. This fixation can be carried out before or at the same time as the pole surface is shaped.
Oppfinnelsen skal forklares nærmere i tilslutning til tegningen, på hvilken fig. 1 viser et sideriss av en magnetkjerne anbragt mellom to verktbydeler, fig. 2 et enderiss av anordningen på fig. 1, og fig. 3 er et sideriss av en magnetdel med skjermvikling sett i snitt og med et! verktby for fiksering av viklingen. Fig. 1 og 2 viser en laminert magnetkjerne 1 anbragt mellom en fast og en bevegelig verktbydel 2 henholdsvis 3. Magnetkjernens plateelementer holdes sammen av et antall nagler 4. I spor i magnetkjernens polflater 5 er der festet skjermviklinger 6. For å opp-nå at polflatene 5 skal få den bnskedeIplanhet, presses den bevegelige verktbydel 3 mot den faste verktbydel 2, hvorved polflatene 5 utsettes for et hbyt trykk og derved undergår en plastisk deforma - sjon. Denne deformasjon kan hensiktsmessig bevirkes ved at polflatene ved hjelp av den vibrerende verktbydel 3 utsettes for flere mindre stot eller slag. De plateelementer som magnetkjernen er sammensatt av, holdes under formingen av polflatene sammen i side-retningen av vinkelrett til verktbydelens 3 bevegelsesretning ved hjelp av sammenpressbare, ikke viste organer. I visse spesielle tilfelle, avhengig av magnetens konstruksjon og dimensjonering, kan der dog fåes tilstrekkelig mothold ved hjelp av nagleforbindelsen. The invention shall be explained in more detail in connection with the drawing, in which fig. 1 shows a side view of a magnetic core placed between two workshop parts, fig. 2 an end view of the device in fig. 1, and fig. 3 is a side view of a magnet part with shield winding seen in section and with a! workshop for fixing the winding. Fig. 1 and 2 show a laminated magnetic core 1 placed between a fixed and a movable tool part 2 and 3 respectively. The plate elements of the magnetic core are held together by a number of rivets 4. Screen windings 6 are attached to grooves in the magnetic core's pole surfaces 5. To achieve that the pole surfaces 5 are to have the desired flatness, the movable tool part 3 is pressed against the fixed tool part 2, whereby the pole surfaces 5 are exposed to a high pressure and thereby undergo a plastic deformation. This deformation can suitably be effected by subjecting the pole surfaces to several minor shocks or blows with the help of the vibrating tool part 3. The plate elements of which the magnetic core is composed are held together during the shaping of the pole faces in the lateral direction perpendicular to the direction of movement of the tool part 3 by means of compressible, not shown, members. In certain special cases, depending on the construction and dimensioning of the magnet, however, sufficient resistance can be obtained by means of the rivet connection.
