Buthini ubunzima bomphezulu wentsimbi yentsimbi engqukuva?

Xa kuziwa kubunzima bomphezulu wentsimbi yentsimbi ejikelezayo, kukho izinto ezininzi ekufuneka ziqwalaselwe. Enye yezinto eziphambili ezimisela ukuqina komphezulu we-alloy steel bar yinkqubo yokuvelisa.Abavelisi bemivalo yentsimbi ebunjiweyozaziwa ngokuvelisa umgangatho ophezulu wealloyi imivalo engqukuva enobunzima obubalaseleyo bomphezulu.
Ukuqina komphezulu we-alloy iron bar ngeenxa zonke kubaluleke kakhulu ekusebenzeni kwayo kwizicelo ezahlukeneyo. Nokuba ngoomatshini bemizi-mveliso, ulwakhiwo okanye iinxalenye zeemoto, ukukwazi kwentsimbi ukumelana nokuguga nokukrazuka kubalulekile. Apha kulapho ibha yentsimbi eyi-20mm ingena khona. Intsimbi ejikelezileyo yentsimbi yaziwa ngobulukhuni bayo obukhethekileyo bomphezulu, iyenza ilungele usetyenziso olufunayo.
Ukongeza kwi-alloy yentsimbi ekhandiweyo imivalo engqukuva nayo idlala indima ebalulekileyo ekuboneleleni ngobulukhuni bomphezulu obugqwesileyo.Ingxubevange yentsimbi ejikelezayo yebariyaziwa ngokuqina kwayo kunye nokukwazi ukugcina ubulukhuni bayo bomphezulu naphantsi kweemeko ezinzima. Xa zidibaniswe neentsimbi ezijikelezayo, zenza udibaniso olunamandla lwamandla kunye nokuqina.
Ukuqina komphezulu wentsimbi yentsimbi engqukuva ngokuqhelekileyo kulinganiswa kusetyenziswa isikali sobunzima beRockwell. Esi silinganisi sibonelela ngendlela esemgangathweni yokumisela ubunzima bezinto ezahlukeneyo, kuquka intsimbi. Ngokusebenzisa esi sikali, abavelisi kunye neenjineli banokuqinisekisa ukuba i-alloy iron bar round bar idibana neenkcukacha zokuqina komphezulu ezifunekayo kwisicelo esithile.

Ukushwankathela, ukuqina komphezulu weingxubevange yentsimbi baryeyona nto iphambili ekumiseleni ukusebenza kwayo kunye nokuqina kwayo. Ngobuchule bobuchwephesha bentsimbi ekhandiweyo abavelisi beebhari ezijikelezayo kunye nokufumaneka kweentsimbi eziphezulu ezijikelezayo ezifana ne-20 mm yentsimbi yentsimbi ejikelezayo, imboni inokuthembela kubulukhuni obuphezulu bezi zixhobo ukunyusa ukusebenza, izicelo ezifunwayo. Nokuba ngumatshini onzima, izixhobo zokwakha okanye izixhobo ezichanekileyo, intsimbi yealloyi engqukuva yentsimbi enobunzima obuphezulu bomphezulu yeyona nto iphambili ekusebenzeni okungapheliyo kunye nokuthembeka.
