Njengengxenye yobuchwepheshe obuphezulu bezimoto, ukucutshungulwa kwamabhulokhi enjini kungena kancane kancane emabhizinisini amakhulu. Ibhulokhi yenjini iyingxenye enodonga oluncane futhi enezimbotshana, edinga ukunemba okuphezulu kakhulu kwezinqubo ezahlukahlukene zokucubungula, futhi ikhwalithi yokucubungula ingxenye ithinta ngqo ukusebenza kwenjini.

I-engine block iyingxenye efana nebhokisi enesakhiwo esiyinkimbinkimbi esinama-porous esinezindonga ezincane, okulula ukusilimaza ngesikhathi sokucutshungulwa kwayo, okudinga ukulawula okuqinile kokunemba kwayo. Njengamanje, ukucutshungulwa nokukhiqizwa kwezinjini ikakhulukazi kubhekisela ekuqedeni ukukhiqizwa emigqeni eguquguqukayo ngaphansi kokulawulwa kwezikhungo zemishini ye-CNC. Lobu buchwepheshe bunezidingo eziphezulu zobuchwepheshe obuzenzakalelayo kanye nezindleko zokukhiqiza eziphansi. Ngaphezu kwalokho, ekucubungulweni kwe-cylinder block, ukunemba kwanoma yisiphi isixhumanisi kufanele kube phezulu kakhulu, ngaphandle kwalokho kunzima ukuhlangabezana nezidingo ezijwayelekile zale nqubo. Okulandelayo inqubo ethile yobuchwepheshe yokucubungula isilinda:

1. I-cylinder surface processing

Ukucutshungulwa kwangaphezulu kwesilinda kuhlukaniswe ikakhulukazi ekucubunguleni indiza kanye nokucubungula igebe. Umshini wendiza wenziwa ikakhulukazi ukugaya ubuso bokuphela, njengokuthi: ukucubungula ubuso obuphezulu, ubuso obuphansi kanye nobuso bangaphambili nabangemuva. Ukucutshungulwa kwe-voids kuvame ukudinga izinqubo ezifana nokubhora, ukucija, ukubhola, ukuphinda uchofoze, kanye nokuthepha, okufaka imbobo yejakhethi yamanzi, izimbobo ezikhwezwayo, izimbobo zokuxhuma, izimbobo zesilinda se-piston, izimbobo zikawoyela, njll.

2. Inqubo ye-cylinder machining

Inqubo yomshini we-cylinder block ingahlukaniswa cishe ngezinhlelo ezine: ukucubungula iphrofayili eyinhloko, ukucubungula ikholomu yembobo eyinhloko, ukuhlolwa kokuhlanza, nokucubungula isakhiwo esisizayo. Izinhlelo ezahlukene zinesibopho semikhakha ehlukene kanye namazinga ahlukene okuma. Isibonelo: ingxenye yohlelo isebenzisa indlela yokuma egcwele enezikhonkwane ezimbili, futhi abanye basebenzisa inkomba enzima 3 eyodwa 2 eyodwa] indlela yokumisa egcwele. Ngaphezu kwalokho, indawo yokubeka ngezindlela ezihlukene nayo inomehluko phakathi kwendawo engaphansi kanye nesiphetho. Enqubweni yomshini we-cylinder block, kuyinqubo ebaluleke kakhulu yokwenziwa kwezindawo ezingaphansi neziphetho ze-cylinder block.

3. Isiteji sokuhlukanisa i-cylinder machining

Ukucutshungulwa kwe-cylinder kungahlukaniswa ngamamojula amabili, i-roughing kanye nokuqeda. Imojula ngayinye ingahlukaniswa izingxenye ezimbili. Wonke umugqa wokukhiqiza uhlukaniswe izingxenye ezintathu: iyunithi ye-roughing, i-semi-finishing unit kanye neyunithi yokuqedela. Esigabeni ngasinye, umkhiqizo udinga ukubekwa ngokwesidingo futhi ukukhiqizwa okuhluzekile kufanele kwenziwe.
