Ubuchwepheshe bokukhiqiza
Inqubo yokukhiqiza ibha ye-mandrel iqukethe izinyathelo eziningana eziyinkimbinkimbi futhi ezinembile. Okokuqala ukuncibilika kwezinto, okuqinisekisa ukufana nokuhlanzeka kwe-core bar. Khona-ke ukukhanga, ngenqubo yokubumba, okusanhlamvu kwezinto ezibonakalayo kuyacwengisiswa, ngaleyo ndlela kuthuthukise izakhiwo zayo zemishini kanye nempilo yesevisi. I-mandrel eyakhiwe idinga ukwelashwa kokushisa, inqubo esusa ukucindezeleka kwangaphakathi futhi ikhulise ubulukhuni nokugqoka ukumelana kwe-mandrel. Ngemva kwalokho, machining, kuhlanganise turning, Milling kanye neminye imisebenzi, kwenza mandrel ukuhlangabezana nezidingo nokunemba design. Isinyathelo sokugcina ukwelashwa okungaphezulu, njengokucisha, ukuthulisa, njll., ukuthuthukisa ukumelana nokugqwala kanye nobulukhuni bobuso be-mandrel.
Ububanzi besicelo kanye nokucaciswa
Ibha ye-Mandrel isetshenziswa kabanzi ezinhlotsheni ezahlukahlukene zezigayo eziginqikayo, njengeMPM (isigayo esinama-multi-pass rolling), i-PQF (isigayo esinembayo esiphezulu) kanye ne-FQM (isigayo esisheshayo). Ukucaciswa kwayo okuhlukahlukene, okusuka ku-Φ80 mm kuya ku-500 mm ububanzi, ubude obusuka ku-2500 mm kuya ku-17,500 mm, kungahlangabezana nezidingo ezahlukene zokukhiqiza.
Ukukhetha okubalulekile
Izinto zebha ye-mandrel ngokuvamile i-AISI H13 noma i-4Cr5MoSiV1 ejwayelekile kazwelonke kanye ne-36CrNiMoV6. Lezi zinto zinezakhiwo ezinhle kakhulu zokushisa okuphezulu namandla emishini ukuze kugcinwe ukuzinza ekushiseni okuphezulu nasezindaweni ezicindezelayo. I-non-metallic inclusions ku-mandrel impahla kudingeka ukuba ingabi ngaphezu kuka-1.0 grade A, B, C no-D, futhi usayizi okusanhlamvu kufanele sifinyelele 8 grade noma ngaphezulu. Lezi zidingo eziqinile zezinto ezibonakalayo ziqinisekisa izinga eliphezulu nokuthembeka kwebha ye-mandrel.
Impahla yemishini
Izakhiwo ezinconyiwe zemishini yebha ye-mandrel yezinto ezibonakalayo ze-H13 zimi kanje: Okwe-mandrel enobubanzi obungu-≤200 mm, amandla aqinile yi-1127-1274 mpa, amandla okukhiqiza ngu-≥931MPa, ukuphakama kungu-≥8%, ukuncipha kwesigaba ngu-≥25%, umsebenzi womthelela ngu-≥20J, futhi ubulukhuni bu-HB350-390; Ku-mandrel enobubanzi > 200 mm, amandla ayo okubamba 1078-1274 mpa, amandla esivuno ≥882MPa, ubude ≥8%, ukuncipha kwesigaba ≥25%, umsebenzi womthelela ≥20J, ubulukhuni bungu-HB330-375.
