Kuseri Kwezviitiko: Magadzirirwo Akaitwa Neodymium Magnets Anogadzirwa

Mumaindasitiri umo simba remagineti, kutungamira kutarisisa, uye compact dhizaini hazvigone kutaurirana,U-shaped neodymium maginetimirai semagamba asina kuimbwa. Asi magineti aya ane simba, ane chimiro chakasiyana anoberekwa sei? Rwendo rwekubva pahupfu mbishi kuenda kune yakakwira-inoita magineti workhorse ibasa resainzi yemidziyo, huinjiniya hwakanyanya, uye nekuchenjera kutonga kwemhando. Ngatipindei mukati mefekitari pasi.

Raw Materials: The Foundation

Izvo zvese zvinotanga ne "NdFeB" triad:

• Neodymium (Nd): Nyeredzi yezvinhu zvisingawanzo pasi, zvichigonesa simba remagineti risingaenzaniswi.
• Simbi (Fe): Musoro wemusana.
• Boron (B): Iyo inodzikamisa, inosimudzira kumanikidza (kupokana kune demagnetization).

Zvinhu izvi zvakasanganiswa, zvinonyungudutswa, uye zvinokurumidza kutonhodzwa kuita maflakes, zvobva zvagayiwa kuita hupfu hwakatsetseka, hudiki-diki. Zvikuru, hupfu hunofanirwa kunge husina oxygen (inogadziriswa muinert gas / vacuum) kudzivirira oxidation inoremadza magineti.

Danho 1: Kudzvanya - Kuumba Ramangwana

Hupfu hunotakurwa muzviumbwa. Kune magineti akaumbwa neU, nzira mbiri dzekutsikirira dzinotonga:

1. Isostatic Pressing:
   • Hupfu hwakaputirwa muforoma inochinjika.
   • Yakaiswa kune yakanyanya-yakakwirira hydraulic pressure (10,000+ PSI) kubva kumativi ese.
   • Inogadzira padhuze-net-shape blanks ine yunifomu density uye magineti kurongeka.
2. Transverse Pressing:
   • A magnetic field inogadzirisa zvimedupanguvakudzvanya.
   • Yakakosha pakuwedzera simba remagineti(BH)maxpedyo nematanda eU.

Nei zvichikosha: Particle alignment inosarudza simba remagineti rinotungamira - U-magineti isina kurongeka inorasikirwa> 30% kunyatsoshanda.

Danho rechipiri: Sintering - Iyo "Bonding Fire"

Iwo akadzvanywa "girinhi" zvikamu zvinopinda vacuum sintering furnaces:

• Kupisa kusvika ≈1080°C (padyo nenzvimbo inonyungudika) kwemaawa.
• Zvimedu zvinosanganiswa kuita dense, yakasimba microstructure.
• Inononoka inotonhorera inokiya mu crystalline chimiro.

Dambudziko: maU-maumbirwo anowanzoita kurwisana nekuda kwekusaenzana kwehuwandu. Fixture dhizaini uye chaiyo tembiricha curves yakakosha kuchengetedza dimensional kugadzikana.

Danho rechitatu: Machining - Precision mune Yese Curve

Sintered NdFeB ine brittle (senge ceramic). Kuumba iyo U kunoda diamond-chishandiso mastery:

• Kukuya: Mavhiri akavharwa nedhaimondi akacheka curve yemukati uye makumbo ekunze kusvika kushiviriro ye ± 0.05 mm.
• Wire EDM: Kune yakaoma U-profiles, waya yakachajwa inopfungaira zvinhu zvine micron kunyatsoita.
• Chamfering: Mipendero yese inokwenenzverwa kudzivirira chipping uye kutarisisa magineti flux.

Chokwadi chinonakidza: NdFeB yekukuya sludge inopfuta zvakanyanya! Anotonhodza masisitimu anodzivirira pfarivari uye anotora zvimedu zvekudzokorodza.

Nhanho 4: Kupeta - Kana Magnet Asangana Origami

Imwe nzira yeU-magineti akakura:

1. Rectangular zvidhinha zvinosiiwa uye pasi.
2. Kupisa kusvika ≈200 ° C (pasi peCurie tembiricha).
3. Hydraulically yakakotama kuita "U" inopesana nemazvo inofa.

The Art: Kukurumidza = kutsemuka. Kunyanya kutonhora = kuputsika. Tembiricha, kudzvanywa, uye bend radius zvinofanirwa kuenderana kudzivirira madiki mafractures anonetesa magineti.

Danho 5: Kupfekedza - The Armor

Bare NdFeB inoora nekukurumidza. Coating is non-negotiable:

• Electroplating: Nickel-copper-nickel (Ni-Cu-Ni) katatu akaturikidzana anopa kusimba kwakasimba kwekudzivirira.
• Epoxy/Parylene: Zvekurapa/zvakatipoteredza zvikumbiro uko simbi ions inorambidzwa.
• Specialty: Goridhe (electronics), Zinc (inodhura-inoshanda).

U-Shape Dambudziko: Kupfekedza iyo yakasimba yemukati curve zvakaenzana inoda nyanzvi yekuputira mbiya kana marobhoti ekupfapfaidza masisitimu.

Nhanho 6: Magnetizing - Iyo "Kumuka"

Iyo magineti inowana simba rayo kwekupedzisira, kudzivirira kukuvadzwa panguva yekubata:

• Yakaiswa pakati pemakoiri makuru anofambiswa necapacitor.
• Yakaiswa kune pulsed field> 30,000 Oe (3 Tesla) yemamilliseconds.
• Kutungamira kwemunda kunoiswa perpendicular kune hwaro hweU, kurongedza matanda pamazano.

Key nuance: U-magineti anowanzoda akawanda-pole magineti (semuenzaniso, chinjana mapango mukati memukati mechiso) yekushandisa sensor/motor.

Nhanho yechinomwe: Kudzora Kwemhando - Kupfuura Gauss Meters

Yese U-magineti inoedzwa zvisina tsitsi:

1. Gaussmeter / Fluxmeter: Inoyera nzvimbo yepasi & flux density.
2. Coordinate Measuring Machine (CMM): Inosimbisa micron-level dimensional kurongeka.
3. Salt Spray Testing: Inobvumira kuvhara kusimba (semuenzaniso, 48-500+ maawa kuramba).
4. Dhonza Miedzo: Yekubata magineti, inosimbisa simba rekunamatira.
5. Demagnetization Curve Analysis: Inosimbisa (BH) max, Hci, HcJ.

Marema? Kunyange 2% kutsauka kunoreva kurambwa. U-maumbirwo anoda kukwana.

Nei iyo U-Shape Inoda Premium Craftsmanship

1. Stress Concentration: Bend nemakona injodzi dzekutyoka.
2. Flux Path Kutendeseka: Asymmetric maumbirwo anokudza zvikanganiso zvekugadzirisa.
3. Coating Uniformity: Inner curves inoteya mabhubhu kana mavara matete.

"Kugadzira U-magineti hakusi kungogadzira zvinhu - ndizvokurongaphysics."

Mhedziso: Iko Injiniya Inosangana neArt

Nguva inotevera paunoona magineti eU-yakaita neodymium yakamisa mota inomhanya kwazvo, ichichenesa simbi dzakadzokororwa, kana kugonesa budiriro yezvokurapa, yeuka: curve yayo inoyevedza inovanza saga yekurongeka kweatomu, kupisa kwakanyanya, kurongeka kwedhaimani, uye kusimbiswa kusingadzoreki. Uku hakusi kugadzira chete — ndiko kukunda kwakanyarara kwesainzi inosundidzira miganhu yemaindasitiri.

Kufarira magineti akaumbwa neU?Govera zvaunofunga - isu tichakufambisira maze yekugadzira iwe.
