Izixhobo kunye nezixhobo ezisetyenziselwa ukukhwabanisa simahla zilula, zizonke kwaye ziphantsi. Xa kuthelekiswa nokuphosa okungenanto,simahla ukwenzakuphelisa i-shrinkage cavity, i-shrinkage porosity, i-porosity kunye nezinye iziphene, ukwenzela ukuba i-blank ibe neepropati eziphezulu zoomatshini.Forgingszilula ngokwemilo kwaye zibhetyebhetye ekusebenzeni. Ngoko ke, kubaluleke kakhulu ekwenzeni oomatshini abanzima kunye namalungu abalulekileyo.
Indawo yosetyenziso
Iifogi zasimahlazilawulwa ngokusebenza ngesandla kwemilo kunye nobukhulu beforgings, ngoko keukwenza ukuchanekaiphantsi, isibonelelo sokulungisa sikhulu, ubungakanani babasebenzi bukhulu, imveliso ayikho phezulu, ngoko ke isetyenziswa ikakhulu kwimveliso enye, encinci.
I-1) Ubungakanani be-billet kunye nobukhulu obuphakathi kufuneka buhambelane neendawo zokusebenza zenkqubo nganye, njengomlinganiselo wobude be-diameter (H / D) yezinto eziphathekayo ngaphambi kokuphazamiseka yi-2-2.5, kunye nedatha ye-empirical yokuguqulwa kwecandelo xa udweba. ngaphandle.
2) kuyimfuneko ukuqikelela utshintsho lobungakanani obungenanto kwiukwenza iinkqubo,umzekelo, ukuphakama okungenanto kuyancitshiswa xa kubethelwa, ngokubanzi amaxesha angama-1.1 obude bokubumba; Xa i-core shaft reaming inyuka.
I-3) i-indentation yecandelo, kufuneka iqinisekise ukuba inxalenye nganye ye-forging inomthamo owaneleyo, njengakwi-shaft yesinyathelo, i-crankshaft okanye i-gear boss billet, yenza umsebenzi omhle wokusabalalisa umthamo wecandelo ngalinye.
4) Niniukwenzangemililo emininzi, ingqwalasela kufuneka ihlawulwe kumathuba okufudumeza umlilo ngamnye phakathi. Ukuba iforgingszitsalwa ixesha elide kakhulu ekuqaleni, ubukhulu beziko akwanelanga ukubeka kwiifogi ezide ngexesha lokufudumeza kwesibini. Ukuze kuqinisekiswe ubungakanani kunye nomgangatho we-forging, ingqwalasela eyodwa kufuneka ihlawulwe kwi-deformation yomlilo emva kwe-Z kunye nokulawulwa kweqondo lokushisa lokuqala kunye nelokugqibela emva kwe-Z.
5) Kuyimfuneko ukuba kuqinisekiswe ukuba kukho isibonelelo esaneleyo sokunquma emva kokugqiba emva kuka-Z, kwaye ingqalelo kufuneka ihlawulwe:
(1) Ngenxa yokuba kwinkqubo yokucinezela igxalaba, ukufuduka, ukubetha kunye nokunye, kukho into eyenzeka ngokuzoba kunye nokuncipha kwindawo engenanto, ekufuneka ishiye isibonelelo sokunxiba kwinkqubo ephakathi;
(2) Ukubumba ixesha elidei-shaft forgings(ezifana nee-crankshafts, njl.) kunyeforgingsngeebhloko zeconcave, ngenxa yokuba ubungakanani babo ubude abunakuphinda buphazamiseke, kufuneka kuqikelelwe ukuba ubungakanani bendlela yobude buya kwandiswa kancinane ekunxibeni kwaye kukhokelela ekunyamezeleni.

Ukuqulunqa.
6) Xa ukhetha izixhobo, abantwana kufuneka basebenzise izixhobo eziqhelekileyo. Xa ibhetshi yemveliso inkulu, izixhobo ezikhethekileyo okanye ukubunjwa kwamavili kunokwenziwa ukuphucula umgangatho kunye nemveliso ye-forgings.
7) Ngokobukhulu kunye nomgangatho wesithuba esingenanto, khetha izixhobo ezikhoyo kwi-workshop.
