Magiyakudalira miyeso yawo yamapangidwe ndi mphamvu zakuthupi kuti athe kulimbana ndi katundu wakunja, zomwe zimafuna kuti zipangizo zikhale ndi mphamvu zambiri, zolimba komanso zolimba; chifukwa cha zovuta mawonekedwe a magiya, ndizidazimafuna kulondola kwambiri, ndipo zida zimafunikiranso kupanga kwabwino. Zida zomwe zimagwiritsidwa ntchito kwambiri ndi zitsulo zopukutira, zitsulo zotayidwa, ndi chitsulo.
1. Chitsulo chopukutira Malinga ndi kuuma kwa dzino, chimagawidwa m'magulu awiri:
Pamene HB ＜350, imatchedwa pamwamba pa dzino lofewa
Pamene HB ＞350, amatchedwa pamwamba dzino lolimba
1.1. Kuuma kwa mano HB＜350
Njira: kupanga chopanda kanthu → kukhazikika - kutembenuka movutikira → kuzimitsa ndi kutentha, kumaliza
Zomwe zimagwiritsidwa ntchito kawirikawiri; 45 #, 35SiMn, 40Cr, 40CrNi, 40MnB
Mawonekedwe: Imagwira bwino ntchito yonse, pamwamba pa dzino imakhala ndi mphamvu zambiri komanso kulimba, ndipo pachimake dzino chimakhala cholimba. Pambuyo kutentha mankhwala, mwatsatanetsatane waMagiyakudula kumatha kufika 8 magiredi. Ndi yosavuta kupanga, yotsika mtengo, ndipo imakhala ndi zokolola zambiri. Kulondola sipamwamba.
1.2 Kuuma kwa mano HB ＞350
1.2.1 Mukamagwiritsa ntchito chitsulo chapakati cha carbon:
Njira: Kupanga mopanda kanthu → kukhazikika → kudula movutikira → kuzimitsa ndi kutenthetsa → kudula bwino → kuzimitsa pafupipafupi komanso kwapakatikati → kutentha pang'ono → kukulitsa kapena kuthamangitsa kuthamangitsa, kugunda kwamagetsi.
Zida zomwe zimagwiritsidwa ntchito kwambiri:45, 40Cr, 40CrNi
Mawonekedwe: Kulimba kwa dzino ndikwambiri HRC = 48-55, mphamvu yolumikizana ndi yayikulu, ndipo kukana kwa mavalidwe ndikwabwino. Pakatikati pa dzino limakhala lolimba pambuyo pozimitsa ndi kutentha, limakhala ndi mphamvu yotsutsa komanso kunyamula katundu wambiri. Kulondola kumachepetsedwa ndi theka, mpaka pamlingo wa 7 wolondola. Zoyenera kupanga misa, monga magiya othamanga apakatikati komanso apakatikati pamagalimoto, zida zamakina, ndi zina.
1.2.2 Mukamagwiritsa ntchito chitsulo chochepa cha carbon: Kupanga chopanda kanthu → kukhazikika → kudula movutikira → kuzimitsa ndi kutenthetsa → kudula bwino → kubisa ndi kuzimitsa → kutentha pang'ono → kukupera mano. Mpaka 6 ndi 7 misinkhu.
Zomwe zimagwiritsidwa ntchito kawirikawiri; 20Cr, 20CrMnTi, 20MnB, 20CrMnTo Mbali: Kulimba kwa mano ndi kubereka mwamphamvu. Pakatikati pake pali kulimba kwabwino komanso kukana mphamvu. Ndioyenera kuthamanga kwambiri, kunyamula katundu wolemetsa, kutumizira mochulukira kapena nthawi zokhala ndi zofunikira zamapangidwe, monga zida zazikulu zotumizira ma locomotives ndi magiya oyendetsa ndege.
2. Chitsulo choponyera:
Pamene azidam'mimba mwake d> 400mm, dongosolo ndi zovuta, ndi forging ndi zovuta, kuponyedwa zitsulo zakuthupi ZG45.ZG55 angagwiritsidwe ntchito normalizing. Normalization, kuzimitsa ndi kutentha.
3. Chitsulo choponyera:
Kukana kwamphamvu kumamatira ndi dzimbiri, koma kukana kukhudzidwa ndi abrasion. Ndizoyenera kugwira ntchito yokhazikika, mphamvu yochepa, liwiro lotsika kapena kukula kwakukulu ndi mawonekedwe ovuta. Ikhoza kugwira ntchito pansi pa kuchepa kwa mafuta ndipo ndi yoyenera kufalitsa poyera.
4. Zachitsulo:
Nsalu, matabwa, pulasitiki, nayiloni, yoyenera kuthamanga kwambiri komanso katundu wopepuka.
Posankha zida, ziyenera kuganiziridwa kuti momwe magiya amagwirira ntchito ndi osiyana, komanso mitundu yolephera ya mano a zida ndi yosiyana, yomwe ndi maziko owerengera mphamvu zama giya ndi kusankha kwa zida ndi kutentha. mawanga.
1. Pamene mano a gear amathyoledwa mosavuta pansi pa katundu wokhudzidwa, zipangizo zolimba bwino ziyenera kusankhidwa, ndipo chitsulo chochepa cha carbon chingasankhidwe kuti chizimitse ndi kuzimitsa.
2. Pakutumiza kotsekeka kothamanga kwambiri, dzino limakhala losavuta kuponya, kotero zida zokhala ndi kulimba kwa mano ziyenera kusankhidwa, ndipo kuuma kwa chitsulo chapakati kungagwiritsidwe ntchito.
3. Pakuti otsika-liwiro ndi sing'anga-katundu, pamene zida kuthyoka, pitting, ndi abrasion zikhoza kuchitika, zipangizo zabwino makina mphamvu, dzino pamwamba kuuma ndi zina zonse mabuku makina katundu ayenera kusankhidwa, ndi sing'anga-mpweya mpweya zitsulo kuzimitsidwa ndi kupsa mtima angathe. kusankhidwa.
4. Yesetsani kukhala ndi zida zazing'ono, zosavuta kuzisamalira, ndikuganiziranso zothandizira ndi kupereka. 5. Pamene kukula kwapangidwe kumakhala kofanana ndipo kukana kuvala kuli kwakukulu, zitsulo za alloy ziyenera kugwiritsidwa ntchito. 6. Zida ndi luso lazopangapanga.
