Ungafinyeza kanjani umjikelezo wokubumba umjovo emshinini wokubumba umjovo we-china?

Kulo mphakathi wamabhizinisi oqhubeka uqhudelana, ukuthuthukisa ukusebenza kahle kokukhiqiza kuyindaba edinga ukunakwa. Lesi sihloko sichaza izindlela ezihlukahlukene zokuthuthukisa umjikelezo womjovo ngokusebenzisa okukhona noma okusanda kwakhiwa imishini yokubumba umjovo we-china noma isikhunta

Umjikelezo womjovo

I umjikelezo womjovo umshini wokubumba umjovo we-china oqhutshwa ngamanzi ubhekisela ekuqaleni kokubopha isikhunta ekubambeni kwesikhunta esilandelayo.. I-Mold clamping ngokuvamile ihlukaniswe izigaba ezine: fast isikhunta clamping, isikhunta kancane clamping, ukuvikelwa kwesikhunta esinengcindezi ephansi kanye nokucindezela kwesikhunta esicindezelayo.

Umjovo uqala ngemva kokuqedwa kokuqinisa ingcindezi ephezulu, futhi ihlukaniswe yaba izigaba eziningi. Ipulasitiki encibilikisiwe igcwalisa umgodi ngesikhathi sokujova. Lapho umgodi ugcwele, ingcindezi ikhuphuka kakhulu, ngakho ukuphela komjovo kubizwa nangokuthi isigaba sokupakisha.

Lapho isilawuli singafanelekile, umkhiqizo ophelile uzoba nama-burrs.Ingcindezi yokubamba iqala ngemva kokuqedwa komjovo. Empeleni, ukupholisa kuqala ngemva kokugcwalisa umgodi, leyo, iqala kusukela ekubambeni kwengcindezi. Lapho isikhunta sipholile, umkhiqizo ophelile uyancipha ngaphansi kwamakhaza.

Umsebenzi wokubamba ukucindezela ukudlula kumgijimi obandayo ongakaqini, futhi ugcwalise izikhala ezakhiwe ukushwabana ngengcindezi yokubamba ngokuvamile ephansi kunokucindezela komjovo, ukuze umkhiqizo ophelile ugcwale (ngaphandle kwamazinyo) lapho lidilizwa.

Lapho umgijimi obandayo eqiniswa, akusho lutho ukubamba ukucindezela futhi, futhi ingcindezi ingaqedwa. Ingcindezi yokubamba ingahlukaniswa ngezigaba eziningi, futhi ukucindezela kokubamba kwesigaba ngasinye kuhlukile (ngokuvamile kuncipha isinyathelo ngesinyathelo), ehlukaniswa yisikhathi. Isikhathi esiphelele sokubamba sinqunywa isisindo somkhiqizo oqediwe noma ukungabi khona kwama-dent kumkhiqizo ophelile. Lungisa kusukela esikhathini esifushane sokubamba, futhi wandise isikhathi sokubamba umjovo ngamunye, kuze kube yilapho isisindo somkhiqizo ophelile singasakhuli noma amazinyo ayamukeleka, isikhathi sokubamba asidingi ukwanda.

I “isikhathi sokupholisa” ipharamitha ebekwe emshinini wokubumba umjovo we-china yinkathi yesikhathi kusukela ekuqedweni kwengcindezi ebambe ukuvulwa kwesikhunta., kodwa ukupholisa kuqala ngokushesha lapho isikhunta sigcwaliswa ngepulasitiki. Inhloso ye “isikhathi sokupholisa” ukwenza umkhiqizo oqediwe uqhubeke uphola futhi uqina ukuze ungakhubazeki ngomjovo lapho ujovwa.. Kufanele kushiwo ukuthi “isikhathi sokupholisa” isuselwa ekuhloleni.

I-clamping
