Ndodo ya hydraulic, kukankha-kukoka ndodo kuzimitsa ndi kutenthetsa mzere wopanga

1. Zofunikira zaukadaulo

1. Cholinga

Amagwiritsidwa ntchito pakuwotcha kwathunthu ndi kutenthetsa kwa ndodo za hydraulic ndi zokankhira-koka.
2. Magawo a workpiece

1 ) Zogulitsa: 45 # zitsulo, 40Cr, 42CrMo

2) Mtundu wazinthu (mm):

Diameter: 60 ≤ D ≤ 150 (chitsulo chozungulira chokhazikika)

Utali: 2200mm ~ 6000mm;

3) Chitsulo chozungulira chimatenthedwa ndi kutentha kozimitsa ndi mafupipafupi apakati ndiyeno utakhazikika kuti uzimitse chithandizo, ndipo chithandizo cha kutentha chimachitidwa pa intaneti.

Kuzimitsa kutentha kutentha: 950 ± 10 ℃;

Kutentha Kutentha Kutentha: 650 ± 10 ℃;

4) Mphamvu yamagetsi: 380V ± 10%

5) Linanena bungwe chofunika: 2T/H (kutengera 100mm kuzungulira zitsulo)

3. Zofunikira zaukadaulo pakuzimitsa ndi kutenthetsa zida:

1 ) Kuuma kwapamwamba kwa tsinde lonse ndi 22-27 madigiri HRC, kuuma kochepa sikungakhale kosachepera madigiri 22, ndipo kuuma koyenera ndi madigiri 24-26;

2 ) Kuuma kwa shaft komweko kuyenera kukhala kofanana, kuuma kwa mtanda womwewo kuyeneranso kukhala kofanana, ndipo kufanana kwa shaft kuyenera kukhala mkati mwa madigiri 2-4.

3) Bungwe liyenera kukhala lofanana ndipo zida zamakina zimakwaniritsa zofunikira:

a. Mphamvu zokolola zimaposa 50kgf/mm²

b. Kulimba kwamphamvu kumapitilira 70kgf/mm²

c. Elongation ndi wamkulu kuposa 17%

4 ) Malo otsika kwambiri apakati pa bwalo sangakhale otsika kuposa HRC18, malo otsika kwambiri a 1 / 2R sadzakhala otsika kuposa madigiri a HRC20, ndipo malo otsika kwambiri a 1 / 4R sadzakhala otsika kuposa madigiri a HRC22.

2. Zolemba za workpiece

Malinga ndi zofunikira za wogula, timapereka seti zotsatirazi za masensa a 45-150 kuzungulira zitsulo.

Malinga ndi tebulo latsatanetsatane la workpiece loperekedwa ndi wogula, ma seti 4 a inductors amafunikira, ma seti 4 aliwonse kuti azimitse ndi kutenthetsa. Kutentha kosiyanasiyana kwa workpiece ndi 40-150mm. The quenching kutentha kukwera kachipangizo utenga 800mm × 2 kapangidwe, quenching yunifolomu kutentha sensa utenga 800mm × 1 mapangidwe, ndi kuzimitsa kutentha kuteteza inductor utenga 800mm × 1 kapangidwe kuonetsetsa kutentha yunifolomu. Gawo la kutentha limapangidwa mofananamo.

Chachitatu, ndondomeko yoyendetsera ntchito

Choyamba, ikani pamanja zida zogwirira ntchito zomwe zimayenera kutenthedwa pamzere umodzi ndi wosanjikiza umodzi pa choyikapo chosungirako chakudya, ndiyeno zinthuzo zimatumizidwa pang’onopang’ono kumalo odyetserako ndi makina onyamula, ndiyeno zinthuzo zimakankhidwira ku chakudya. wozungulira wokhotakhota ndi silinda ya mpweya. Wodzigudubuza wokhotakhota amayendetsa zinthu za bar patsogolo ndikutumiza zinthuzo ku choyimitsa chotenthetsera. Ndiye workpiece ndi mkangano ndi quenching Kutentha gawo, ndi Kutentha Kuzimitsira amagawidwa quenching Kutentha Kutentha ndi kuzimitsa kutentha kuteteza kutentha. Mu quenching ndi Kutentha gawo, 400Kw wapakatikati pafupipafupi magetsi ntchito kutenthetsa workpiece, ndiyeno seti awiri a 200Kw wapakatikati mphamvu magetsi ntchito kuteteza kutentha ndi Kutentha.

Kutentha kukatha, chogwirira ntchito chimayendetsedwa ndi wodzigudubuza wokhotakhota kuti adutse mphete yopopera yamadzi yozimitsa kuti azimitse. Kuzimitsa kumalizidwa, kumalowa mu chotenthetsera chotenthetsera chotenthetsera kutentha. Kutentha kwapang’onopang’ono kumagawidwa m’magawo awiri: kutenthetsa kutentha ndi kuteteza kutentha. Gawo lotenthetsera limagwiritsa ntchito mphamvu yapakati ya 250Kw, ndipo gawo losungira kutentha limagwiritsa ntchito magawo awiri amagetsi apakati a 125Kw. Kutentha kukatha, zinthuzo zimatulutsidwa, ndipo ndondomeko yotsatira ikuchitika.
