Kodi moto unayi wamakampani ndi chiyani?

Kodi moto unayi wamakampani ndi chiyani?

1. Kuwonjezera

Njira yogwiritsira ntchito: Mukatenthetsa chitsulo ku Ac3 + 30 ~ 50 madigiri kapena Ac1 + 30 ~ 50 madigiri kapena kutentha pansi pa Ac1 (chidziwitso choyenera chikhoza kufufuzidwa), nthawi zambiri chimazizira pang’onopang’ono ndi kutentha kwa ng’anjo.

Cholinga:

1. Kuchepetsa kuuma, kusintha plasticity, ndi kusintha kudula ndi kuthamanga processing ntchito;

2. Yenga mbewu, kukonza makina, ndi kukonzekera ndondomeko yotsatira;

3. Chotsani kupsinjika kwamkati komwe kumachitika chifukwa cha kuzizira komanso kutentha.

Mfundo zofunikira:

1. Ndi oyenera aloyi structural zitsulo, carbon chida zitsulo, aloyi chida zitsulo, mkulu-liwiro zitsulo forgings, welded mbali ndi zosayenerera zopangira;

2. Nthawi zambiri, annealing ikuchitika mu mkhalidwe wovuta.

2. Kusintha kwachilengedwe

Njira yogwirira ntchito: Yatsani chitsulo mpaka madigiri 30 ~ 50 pamwamba pa Ac3 kapena Accm, ndipo muziziziritsa pamlingo wozizira pang’ono kuposa wa annealing pambuyo posunga kutentha.

Cholinga:

1. Kuchepetsa kuuma, kusintha plasticity, ndi kusintha kudula ndi kuthamanga processing ntchito;

2. Yenga mbewu, kukonza makina, ndi kukonzekera ndondomeko yotsatira;

3. Chotsani kupsinjika kwamkati komwe kumachitika chifukwa cha kuzizira komanso kutentha.

Mfundo zofunikira:

Normalizing nthawi zambiri amagwiritsidwa ntchito ngati njira yopangira kutentha kwa preheat forgings, weldments ndi carburized parts. Kwa chitsulo chochepa cha carbon ndi sing’anga-carbon carbon structural steel ndi zitsulo zazitsulo zochepa zomwe zimakhala ndi zofunikira zochepa, zitha kugwiritsidwanso ntchito ngati chithandizo chomaliza cha kutentha. Kwa zitsulo zapakatikati komanso zapamwamba za aloyi, kuziziritsa kwa mpweya kungayambitse kuzimitsa kwathunthu kapena pang’ono, kotero sikungagwiritsidwe ntchito ngati njira yomaliza yochizira kutentha.

3. Kuthetsa

Njira yogwiritsira ntchito: tenthetsani chitsulo pamwamba pa kutentha kwa Ac3 kapena Ac1, sungani kwa kanthawi, kenako muziziziritsa mofulumira m’madzi, nitrate, mafuta, kapena mpweya.

Cholinga: Kuzimitsa nthawi zambiri ndiko kupeza mawonekedwe olimba kwambiri a martensite, ndipo nthawi zina pozimitsa zitsulo zamtengo wapatali (monga zitsulo zosapanga dzimbiri ndi zitsulo zosavala), ndiko kupeza mawonekedwe amodzi a austenite kuti apititse patsogolo kuvala. ndi kukana dzimbiri.

Mfundo zofunikira:

1. Nthawi zambiri ntchito mpweya zitsulo ndi aloyi zitsulo ndi mpweya okhutira kuposa 0.3%; 2. Kuzimitsa kungapereke kusewera kwathunthu ku mphamvu ndi kuvala kukana mphamvu zachitsulo, koma panthawi imodzimodziyo zidzayambitsa kupsinjika kwakukulu kwamkati ndikuchepetsa mphamvu yachitsulo. Pulasitiki ndi kulimba kwamphamvu, kotero kutentha kumafunika kuti mupeze zinthu zamakina bwino.

4. Kutentha

Njira yogwiritsira ntchito:

Zigawo zazitsulo zozimitsidwa zimatenthedwanso kutentha pansi pa Ac1, ndipo pambuyo posungira kutentha, zimakhazikika mu mpweya kapena mafuta, madzi otentha, ndi madzi.

Cholinga:

1. Kuchepetsa kapena kuthetsa kupsinjika kwamkati mutatha kuzimitsa, kuchepetsa kusinthika ndi kusweka kwa workpiece;

2. Sinthani kuuma, kukonza pulasitiki ndi kulimba, ndikupeza makina omwe amafunikira ndi ntchitoyo;

3. Khola workpiece kukula.

Mfundo zofunikira:

1. Gwiritsani ntchito kutentha pang’ono kuti musunge kuuma kwakukulu ndi kuvala kukana kwachitsulo pambuyo pozimitsa; gwiritsani ntchito kutentha kwapakati kuti muwonjezere kusungunuka ndi kutulutsa mphamvu zachitsulo ndikusunga kulimba kwina; kukhalabe olimba kwambiri komanso pulasitiki makamaka, pakakhala mphamvu zokwanira, kutentha kwakukulu kumagwiritsidwa ntchito;

2. Kawirikawiri, zitsulo ziyenera kutenthedwa pa madigiri 230 ~ 280 ndi zitsulo zosapanga dzimbiri ziyenera kutenthedwa pa madigiri 400 ~ 450, chifukwa kupsa mtima kudzachitika panthawiyi.
