Chithandizo cha Kutentha kwa Carburizing pa Magiya: Kulimbitsa Mphamvu, Kulimba & Kugwira Ntchito

Mu makina otumizira mphamvu amakono, magiya akuyembekezeka kugwira ntchito pansi pa mikhalidwe yovuta kwambiri, kuzungulira kosalekeza, katundu wolemera, liwiro losinthasintha, komanso magwiridwe antchito ataliatali. Zitsulo zachikhalidwe za alloy, ngakhale zili ndi kuuma kwabwino kwamkati, nthawi zambiri sizingathe kupirira ntchito zovuta zotere popanda kulephera pamwamba, kuvulala mano, kusweka, kuwonongeka, ndi kutopa. Kuti tithane ndi mavutowa, chithandizo cha kutentha chimakhala gawo lofunikira kwambiri popanga zida, ndipo pakati pa njira zonse,kuwotchaimadziwika ngati imodzi mwa njira zothandiza kwambiri zolimbitsira pamwamba.

Kukonza zinthu pogwiritsa ntchito kabotolo (kotchedwanso kuti kuuma kwa kabotolo) ndi njira yogwiritsira ntchito zitsulo yomwe imalowetsa kaboni pamwamba pa zida zachitsulo pa kutentha kwambiri. Pambuyo pozimitsa, pamwamba pake pamasintha kukhala chikwama cholimba cha martensitic pomwe pakati pake pamakhalabe kulimba komanso kukana kugwedezeka. Kuphatikiza kumeneku kumakhala kolimba kunja, kolimba mkati. Ichi ndichifukwa chake magiya opangidwa ndi carburised amagwiritsidwa ntchito kwambiri mu ma transmission a magalimoto, ma gearbox a mafakitale, makina olemera, zida zamigodi, ma aerodrome drive, ndi ma robotic.

Kodi Carburizing ndi chiyani?

Kutenthetsa ndi njira yotenthetsera pogwiritsa ntchito kufalikira kwa madzi yomwe imachitika pa kutentha komwe kumakhala pakati pa 880°C - 950°C. Panthawiyi, magiya amatenthedwa mumlengalenga wokhala ndi kaboni wambiri. Maatomu a kaboni amafalikira pamwamba pa chitsulocho, zomwe zimawonjezera kuchuluka kwa kaboni. Pambuyo ponyowa kwa nthawi yofunikira, magiya amazimitsidwa mwachangu kuti apange chivundikiro cholimba cha martensitic.

Kuzama kwa kulowa kwa kaboni kumatchedwa kuya kwa chipolopolo, ndipo kumatha kulamulidwa ndi kutentha kosiyanasiyana, nthawi yogwirira, ndi mphamvu ya kaboni. Kawirikawiri, kuya kwa chipolopolocho kumakhala pakati pa 0.8 mm ndi 2.5 mm, kutengera momwe chigwiritsidwe ntchito, kukula kwa zida, ndi mphamvu yofunikira yonyamula katundu.

N’chifukwa Chiyani Magiya Amafunika Kukonza Magalimoto?

Kukonza mafuta sikuti kungowonjezera kuuma kokha, komanso kumathandizira kwambiri magwiridwe antchito m'mikhalidwe yeniyeni yogwirira ntchito. Ubwino waukulu ndi monga:

1. Kukana Kwambiri Kuvala
   Malo olimba amaletsa kuwonongeka kwa makoma, kusweka kwa maenje, kufalikira kwa madontho, ndi kuwonongeka kwa kutopa kwa pamwamba.

2. Kutha Kunyamula Katundu Kwambiri
   Magiya opangidwa ndi carburised amatha kunyamula katundu wolemera kwambiri ndikutumiza mphamvu yayikulu popanda kusintha.

3. Mphamvu Yopindika Mano Yabwino
   Chiwalo chofewa cha ductile chimayamwa kugwedezeka ndi kugwedezeka, zomwe zimachepetsa chiopsezo cha kusweka kwa dzino.

4. Moyo Wotopa Kwambiri
   Magiya opangidwa ndi carburizing amatha kugwira ntchito kwa maola masauzande ambiri m'malo ozungulira kwambiri.

5. Kuchepetsa Kukangana & Kupanga Kutentha
   Kugwira bwino dzino kumathandiza kuti liziyenda bwino komanso kuti lizigwira ntchito bwino.

Chifukwa cha zabwino izi, kugwiritsa ntchito carburizing kwakhala njira yodziwika bwino yochizira kutentha kwamagalimotozida, makamaka zamagiya a bevel, magiya ozungulira, magiya ozungulira, magiya osiyanitsa, ndi ma shaft otumizira.

Njira Yopangira Carburizing Pang'onopang'ono

Njira yonse yopangira carburing imaphatikizapo magawo angapo, iliyonse yomwe imakhudza magwiridwe antchito omaliza:

1. Kutentha Pasadakhale ndi Kuziziritsa

Magiya amatenthedwa kufika kutentha kwa carburizing komwe chitsulo chimasanduka austenite. Kapangidwe kameneka kamalola kaboni kufalikira mosavuta.

2. Kufalikira kwa Kaboni ndi Kupanga Mlandu

Magiyawo amasungidwa pamalo okhala ndi kaboni wambiri (gasi, vacuum, kapena chopangira carburizing cholimba). Maatomu a kaboni amafalikira mkati, ndikupanga chivundikiro cholimba pambuyo pozimitsa.

3. Kuzimitsa

Kuziziritsa mwachangu kumasintha gawo la pamwamba la kaboni wambiri kukhala martensite—lolimba kwambiri komanso losawonongeka.

4. Kulimbitsa thupi

Pambuyo pozimitsa, kutenthetsa kumafunika kuti kuchepetse kusweka, kulimbitsa kulimba, ndikukhazikitsa kapangidwe kake.

5. Machining Yomaliza / Kupera

Magiya otenthedwa ndi kutentha nthawi zambiri amapukutidwa kapena kukulungidwa kuti akwaniritse mawonekedwe olondola a mano, mawonekedwe osalala a mano, komanso kuwongolera bwino phokoso.

Mitundu ya Carburizing ya Magiya

Ukadaulo wosiyanasiyana wa carburizing wapangidwa, uliwonse uli ndi ubwino wake wapadera.

Mwa iwo,vacuum carburizingimakonda kwambiri kugwiritsa ntchito zida zolondola chifukwa cha kufalikira kwa zikwama zake zofanana, kusamala chilengedwe, komanso kusinthasintha kochepa.

Kusankha Zinthu Zopangira Carburizing

Si zitsulo zonse zomwe sizimawononga ma carburizing. Zipangizo zabwino kwambiri ndi zitsulo zopanda mpweya wambiri zomwe zimakhala zolimba komanso zolimba kwambiri.

Zitsulo zodziwika bwino za carburizing:

• 16MnCr5

• 20CrMnTi

• Chitsulo cha 8620/4320

• 18CrNiMo7-6

• SCM415 / SCM420

Zitsulo zimenezi zimathandiza kuti chivundikiro cha chivundikirocho chikhale cholimba komanso cholimba, komanso cholimba kwambiri—choyenera kugwiritsa ntchito magiya olemera.

Zinthu Zabwino mu Magiya Opangidwa ndi Carburised

Kuti ntchito iyende bwino, zinthu zingapo zofunika ziyenera kulamulidwa:

1. Kuchuluka kwa kaboni pamwamba

2. Kuzama kwa milandu moyenera (ECD)

3. Kusunga mulingo wa austenite

4. Kusokonezeka ndi kukhazikika kwa magawo

5. Kufanana kwa kuuma (58–62 HRC pamwamba)

Njira yoyendetsera bwino ma carburing imatsimikizira kuti magiya amagwira ntchito bwino kwa zaka zambiri popanda kukonza kwambiri.

Kugwiritsa Ntchito Magiya Opangidwa ndi Carburised

Carburizing imagwiritsidwa ntchito kwambiri m'mafakitale komwe kudalirika, kulondola, komanso kupirira katundu wambiri ndikofunikira:

• Ma gearbox a magalimoto ndi makina osiyana siyana

• Matrakitala, migodi ndi zida zolemera

• Magiya a Robotic ndi automation

• Ma gearbox a mphepo

• Ma drive oyendetsa ndege ndi ma transmission a turbine

• Makina oyendetsa sitima zapamadzi

Kulikonse komwe magiya ayenera kupirira kugwedezeka, kupanikizika komanso kupsinjika kwa nthawi yayitali, kuyika magiya mu carburizing ndiye njira yodalirika kwambiri.

Kutenthetsa ndi kutentha kwa carburing kumasintha magiya achitsulo wamba kukhala zida zogwira ntchito bwino zomwe zimatha kupirira malo ovuta. Njirayi imalimbitsa pamwamba kuti isawonongeke komanso kutopa pamene ikusunga mkati mwake wolimba kuti usagwe. Pamene makina akusintha kukhala amphamvu komanso ogwira ntchito bwino, magiya a carburing adzakhalabe ukadaulo wofunikira kwambiri muukadaulo wamakono komanso makina otumizira mphamvu.
