Impilo yesevisi yesikhunta se-carbide esine-cemented ihlobene nezimo zesevisi, ukuklama kanye nenqubo yokukhiqiza, ukufakwa, ukusetshenziswa nokugcinwa kwesikhunta. Ngakho-ke, ukuthuthukisa impilo yesevisi yesikhunta, izinyathelo ezihambisanayo zokuthuthukisa lezi zimo zidinga ukwamukelwa. Izici eziyinhloko ezithinta impilo yesevisi yesikhunta zichazwe kanje.
(1) Umthelela wokuklanywa kwesakhiwo sesikhunta empilweni yesevisi yesikhunta Ukuhluzeka kwesakhiwo sesikhunta kunomthelela omkhulu emandleni okuthwala amafomu; isakhiwo esingenangqondo singabangela ukugxila okukhulu kokucindezeleka noma ukushisa okusebenzayo ngokweqile, ngaleyo ndlela kuphazamise izimo zokusebenza zesikhunta futhi kubangele ukwehluleka ngaphambi kwesikhathi kwesikhunta. Isakhiwo sesikhunta sihlanganisa ukuma kwejometri yengxenye esebenzayo yesikhunta, ubukhulu be-angle yokuguqulwa, ukwakheka kwe-clamping, umhlahlandlela kanye ne-ejection mechanism, igebe lesikhunta, isilinganiso se-aspect ratio ye-punch, i-engeli yokuthambekela kobuso bokuphela, ukuvulwa kwamashaneli amanzi okupholisa kanye nezakhiwo zokuhlangana ezibunjeni ezisebenzayo ezishisayo, njll.
(2) Ithonya lezinto zokubunjwa ze-carbide ezinosimende empilweni yesevisi yesikhunta Ithonya lezinto zokubumba empilweni yesevisi yesikhunta liwumfanekiso ophelele wezici ezifana nohlobo lwempahla yesikhunta, ukwakheka kwamakhemikhali, ukwakheka kwenhlangano, ubulukhuni kanye nekhwalithi ye-metallurgical, phakathi kwayo uhlobo lwezinto ezibonakalayo nobulukhuni bunethonya elisobala kakhulu. Umthelela wohlobo lwezinto zokubumba empilweni yesikhunta likhulu kakhulu.
Ngakho-ke, lapho ukhetha izinto zokubumba, izinto zokubunjwa kufanele zikhethwe ngokufanele ngokuya ngosayizi we-batch wezingxenye. Ukuqina kwezingxenye zokusebenza zesikhunta nakho kunethonya elikhulu empilweni yesikhunta, kodwa ukuphakama kokuqina, isikhathi eside sokuphila kwesikhunta. Kungabonakala ukuthi ubulukhuni besikhunta se-carbide esine-cemented kumele kunqunywe ngokusho kwezakhiwo zokwakha kanye namafomu okuhluleka, futhi ubulukhuni, amandla, ukuqina, ukumelana nokugqoka, ukumelana nokukhathala, njll kufanele kuhambisane kahle nezidingo zokwakha. Ithonya lekhwalithi ye-metallurgical yezinto ezibonakalayo empilweni yesikhunta ayikwazi ukushaywa indiva, ikakhulukazi insimbi ephezulu ye-carbon alloy, eneziphambeko eziningi ze-metallurgical, okuvame ukuba yimbangela yokuqhekeka kwesikhunta kanye nokulimala kwangaphambi kwesikhunta. Ngakho-ke, ukuthuthukisa ikhwalithi ye-metallurgical yezinto ezibonakalayo kuyisici esibalulekile sokuthuthukisa impilo yesikhunta.
Ayini amandla okumelana nokuphuka kwezibungu ze-carbide zikasimende?
Ukumelana nokuphuka kwe-brittle ngesikhathi esisodwa: Izinkomba ezingabonisa ukumelana nesikhathi esisodwa sokuphuka kwesikhunta se-carbide esine-cemented umsebenzi wesikhathi esisodwa sokuphuka, amandla acindezelayo namandla okugoba.
Ukumelana nokuphuka kokukhathala: Kubonakala ngenani lemijikelezo yokuphuka ngaphansi komthwalo othile ojikelezayo noma inani lomthwalo elibangela ukuba isifanekiso siphuke enanini elicacisiwe lemijikelezo. Isikhunta se-carbide esine-cemented singaboniswa izinkomba ezimbalwa ezifana namandla amancane umsebenzi wokuphuka komthelela omningi noma impilo yokuphuka okunomthelela omningi, amandla okukhathala okuqinile nokucindezelayo noma impilo yokukhathala, ukuthintana namandla okukhathala noma impilo yokukhathala yokuxhumana. Ukumelana nokuqhekeka kwe-crack: Uma ama-microcracks esevele ekhona kusikhunta se-carbide esine-cemented, ukumelana kwayo nokuqhekeka kuba buthaka kakhulu. Ngakho-ke, ukuphikiswa okuhlukahlukene kokuqhekeka okuhlolwe kuma-specimens abushelelezi akukwazi ukusetshenziselwa ukuhlola ukumelana nokuqhekeka komzimba wokuqhekeka. Ngokombono we-fracture mechanics, inkomba yokuqina kwe-fracture ingasetshenziswa ukukhombisa ukumelana nokuqhekeka komzimba wokuqhekeka.
