Kalamita Anisotropika Mxarrba, Isotropika Xotta u Niexfa Anisotropic Hard Ferrite
L-iffurmar ta 'kalamita Hard Ferrite huwa l-aktar minn magna tal-istampa mgħammra b'kojl dak li jista' jiġġenera kamp manjetiku estern biex tikseb kalamita anisotropika. Il-materjal biex tagħmel kalamita Anisotropic Hard Ferrite huwa normalment fi stat ta 'slurry imxarrab sabiex il-molekuli jkunu jistgħu jiġu allinjati perfettament fil-proċess tal-iffurmar. Allura aħna nsejħu kalamiti magħmula minn proċess tip bħal kalamiti Hard Ferrite anisotropiċi mxarrba dak li biss jistgħu jiġu manjetizzati matul pre-orjentazzjoni. Il-(BH)max ta 'Ferrite Iebsa anisotropika hija diversi drabi aktar b'saħħitha minn dik tal-kalamita Isotropic Hard Ferrite.
Il-materja prima biex isiru kalamiti Isotropic Hard Ferrite hija ġeneralment fi stat ta 'trab niexef. L-iffurmar huwa minn magna punch dak li ma setax japplika kamp manjetiku estern fuq kalamita. Għalhekk il-kalamiti miksuba sussegwentement jissejħu kalamiti Hard Ferrite isotropiċi niexfa. Il-manjetizzazzjoni fuq kalamita Isotropic Hard Ferrite tista 'ssir bi kwalunkwe orjentazzjoni u mudell preferut skont il-magnetizing yoke.
Hemm ukoll kalamita Hard Ferrite tat-tip wieħed imsejħa kalamita Hard Ferrite niexfa. Huwa magħmul minn trab tal-materjal niexef iżda li jkun orjentat minn kamp manjetiku estern. Il-proprjetà manjetika tal-kalamita Hard Ferrite anisotropika niexfa hija aktar baxxa minn dik anisotropika mxarrba. Normalment il-proċess niexef u anisotropiku jintuża biex jiġi ffurmat kalamita bi struttura kumplessa iżda proprjetà ogħla minn dik isotropika.
Forma u Tolleranza Dimensjonali
Kalamita Ferrite iebsa tista 'tkun iffurmata ekonomikament biċ-ċirku, segment ark, rettangolari, diska, ċilindru, trapezium jew 2 ġeometriji kkombinati f'biċċa waħda. Skont dawn il-ġeometriji bażiċi, l-isfera, il-forma olivarja, u ġeometrija irregolari oħra huma disponibbli permezz ta' proċess ulterjuri ta' magni. Slotting fil-kalamita Hard Ferrite huwa prattikabbli minn qabel id-disinn fil-proċess tat-tħin tal-għodda jew tad-djamanti. Kalamiti Ferrite iebsa bi struttura 3S (super-żgħar, super-kbar u super-irqaq) huma wkoll produċibbli bi proċess ta 'iffurmar imxarrab.
Id-devjazzjoni dimensjonali tal-kalamita Hard Ferrite hija kkontrollata fi ħdan +/-2% qabel ma tiġi mmaxinjata, u tista 'tiġi kkontrollata fi ħdan +/-0.10mm wara li tkun sempliċement mitħuna b'għodda tad-djamanti. It-tolleranza doganali jew il-kontroll preċiż anki +/-0.015mm jista' jinkiseb, iżda għandhom jiġu nnegozjati. Fil-biċċa l-kbira taċ-ċirkostanza, kalamita Hard Ferrite anisotropika mxarrba hija fornuta b'uċuħ li paralleli mal-orjentazzjoni anisotropika mhux mitħuna u uċuħ oħra mitħuna. Id-definizzjonijiet dwar it-tolleranza tal-konċentriċità, it-tond, il-kwadrità, il-perpendikularità u oħrajn jekk jogħġbok irreferi għall-istandard MMPA Nru 0100-00 jew DIN17410 jew ISO2768.
Għodda ta 'Kalamita Ferrite Iebsa
Il-proċess ekonomiku għall-manifattura tal-kalamita Hard Ferrite fi kwantità kbira huwa permezz tal-iffurmar bl-għodda. L-għodda biex tagħmel kalamita Hard Ferrite anisotropika hija konsiderevolment għalja, iżda biex tagħmel kalamita Isotropic Hard Ferrite huwa irħis. Jekk il-kalamita meħtieġa hija bl-istess dijametru, jew l-istess tul u wisa 'meta huwa tip blokka, bħall-għodda kurrenti, allura nistgħu jutilizzaw l-għodda lesta biex moffa kalamiti ħxuna / għoli differenti fil-firxa permissibbli.
Fil-prattika, xi kultant aħna tqatta 'blokka kbira, tħin ċirku / diska ta' dijametru akbar u tip ta 'segment ta' ark tal-magna ta 'dimensjoni mill-qrib f'dik meħtieġa. Dan il-proċess huwa ta 'għajnuna biex tinkiseb dimensjoni preċiża, biex tiffranka l-ispiża tal-għodda meta l-kwantità tal-ordni ma tkunx daqshekk kbira (b'mod partikolari fil-fażi tal-prototip), u biex omoġenizza l-piż u l-fluss ta' kull prodott tal-biċċa. In-nuqqas ta 'produzzjoni ta' kalamita bil-magna huwa għali ħafna spiża.
