Ubuchwepheshe bendabuko bokukhipha ukufa kanye nemishini sekuvuthwe impela, ikakhulukazi imishini yokuphonsa yegumbi elibandayo evundlile kanye nezinqubo zokuphonsa kufa ezivundlile. Umjovo wabo kanye nemishini yokubopha isikhunta inokuguquguquka okuqinile kwenqubo. Ngakho-ke, uma ubuchwepheshe be-extrusion casting bungakwazi ukuhlanganiswa nezisetshenziswa zendabuko zokusakaza ukufa, ukusetshenziswa kwazo okusabalele kuzonqunyelwa. Ukuthatha lesi sinyathelo, kuzovela elinye igatsha lobuchwepheshe bokusakaza nge-extrusion: ubuchwepheshe bokusakaza nge-extrusion die. Ngamanye amazwi, ukusebenzisa ubuchwepheshe be-extrusion casting emshinini we-die casting wendabuko ubuchwepheshe be-extrusion die casting. Ngokusekelwe ezicini zenqubo ye-extrusion die casting ngokwayo, futhi ngokwenza ukuthuthukiswa okuhambisanayo nokulungiswa komshini wendabuko wokufafaza wendabuko, lesi sisetshenziswa siba umshini omusha we-extrusion die casting machine.
1. Ukuqonda Okulungile Nokuphelele Kobuchwepheshe Be-Die Casting kanye Nemisebenzi Yemishini Yokusakaza Yendabuko
Ukubamba izimiso zobuchwepheshe be-extrusion casting, ukumane ukusebenzise emshinini wendabuko wokufa akunzima. Okubalulekile wukweqa imiqondo yendabuko. Kudinga ukuqonda okuphelele nokuphelele kokusebenza kwemishini evamile yokukhipha ukufa, ukuqonda okujulile kwenqubo yokukhipha ukufa kwendabuko, kanye nokuqedwa kwemibono ecatshangwe ngaphambili. Eqinisweni, imishini yesimanje yokufa{3}}yokusakaza isivele iphelele emsebenzini. Abakwazi ukwenza i-die casting evamile kuphela, kodwa futhi ne-extrusion die casting kanye{5}}nokusekelwe ku-extrusion die casting; bangakwazi ukwenza{6}}ingcindezi ephansi ehlukahlukene, ukusakaza kwengcindezi ehlukile, kanye nokusakaza amandla adonsela phansi. Ngokungezwa kwedivayisi ye-vacuum, bangakwazi futhi ukwenza i-vacuum suction cast, i-vacuum die cast, kanye ne-vacuum extrusion die casting. Uma sinweba ukucabanga kwethu ngokuqhubekayo futhi sikuhlanganise -nokucubungula okuqinile kanye nobuchwepheshe be-die forging ukuze senze inqubo eqhubekayo yokulingisa nokukhanga, kuyenzeka futhi ngempumelelo.
Amamodeli amaningi emishini yokusakaza{0}}ekhona kakade anamandla okujova ashintshekayo kanye nesivinini somjovo. Ngokwezici zenqubo-zokusakaza kwengcindezi ephansi, ukusakaza kwengcindezi ehlukile, kanye nokusakaza amandla adonsela phansi, ukwenza lezi zinqubo emishinini yokusakaza efayo evamile{3}}akuyona inkinga. Ukufaka isikhunta esinjalo emishinini yokuphonsa{5}akubizi ngendlela abantu abacabanga ngayo, njengoba akudingeki ukuba kuklanywe ngendlela eyinkimbinkimbi njengokubunjwa kwendabuko{6}}okubunjwayo. Ngeshwa, asivamile ukubona izinhlelo zokusebenza ezifanele noma imibiko ekusebenzeni. Lona umbono oyiphutha, umbono oyiphutha, kanye nokungaqondi kahle kohlelo lokusebenza mayelana nemishini yokufa yendabuko{9}}nezinqubo zokusakaza zendabuko{10}}zokusakaza.
2. Izici Zezinqubo Zokulingisa I-Die Yendabuko Nezisetshenziswa kanye Nokujwayela Kwazo Ku-Extrusion Die Casting
Imishini yokufaka ukufa yendabuko iwela ezigabeni ezimbili: imishini yokufaka isilinda eyinhloko ye-hydraulic (ukukhiya) kanye nemishini yokufaka yokufaka ukufa kwemishini yokufaka. Ngenxa yezindleko eziphansi zokukhiqiza ze-toggle mechanism clamping okokusebenza, lolu hlobo lomshini njengamanje lubusa imakethe.
Isici esiyisihluthulelo semishini yendabuko yokukhipha ukufa ukuthi amamodeli ayo aqanjwe ngokuyinhloko ngokusekelwe kumandla okubamba. Uma sithi umshini wokulingisa ukufa unenani elithile lamathani, sibhekisela kumandla awo okubamba ngamathani. Imishini ye-Extrusion die casting, nokho, ayinazo kuphela izidingo zokuphoqa amandla kodwa futhi namandla okunxeshezelwa kwe-extrusion, futhi la mandla okukhiphayo ayinkomba ebaluleke kakhulu.
Yize kunezinhlobo ezimbili ezihlukene zemishini yokulingisa idaye evamile-i-hydraulic ngokugcwele kanye ne-toggle-awukho umehluko uma kwenziwa i-die casting evamile. Kodwa-ke, inqubo iyahluka uma isetshenziselwa ukusakaza kwe-extrusion die. Umehluko phakathi kokukhishwa kokuminyanisa kanye nokuphonswa kwe-die okujwayelekile useqinisweni lokuthi ngemuva kokugcwaliswa kokuphonswa, ukuminyanisa ukulingisa kunezela isinyathelo lapho isilinda esiyinhloko siqhubekisela phambili ukuphonsa phambili ukuze kunxephezele ukuncipha, kuyilapho ukukhishwa kwefa okujwayelekile kuvumela kuphela ukupholisa kwemvelo ngaphandle kwalesi sinyathelo.
Kuyadingeka futhi ukuqhubeka nokuhlukanisa nokucacisa imiqondo emibili: amandla okucindezela kanye namandla okuqinisa (noma ukumelana nokucindezela). I-clamping force ibhekisela emandleni okuya phambili adingekayo ukuze aqhubekisele phambili isikhunta esinyakazayo, kuyilapho amandla okubamba kuwukumelana okudingekile ukumelana nokugcwalisa kanye nokwandiswa kwesikhunta; kungaba amandla amile (amandla okusabela). Ngakho-ke, lapho usebenzisa ngokuqondile ukuphonsa okukhama emshinini wokuphonsa wendabuko, amandla okubamba kuphela angasetshenziswa, futhi amandla okubamba kuphela ahlinzeka ngamandla okuqhubela phambili. Ubukhulu bamandla okuphoqa bunquma ubukhulu bamandla esinxephezelo sokuminyanisa. Ngakho-ke, emshinini wokuphonsa wokufa wendabuko onama-hydraulic ngokugcwele, amandla amakhulu okubamba nawo angamandla awo aphezulu okubamba, angasetshenziswa futhi njengamandla awo okunxephezela. Amandla amakhulu okukhipha phambili okuya phambili omshini wokulingisa ifa alingana namandla esilinda abambayo aphindaphindeka ngesilinganiso se-lever ye-clamping mechanism, kodwa awakwazi ukudlula amandla acindezelayo umshini wokubopha ongamelana nawo. Uma usebenzisa lesi sisetshenziswa se-extrusion die casting, indawo ehlongozwayo yezingxenye ezingakhiqizwa iyancishiswa ngoba indawo yokuqala yokuvala isikhunta ayifinyeleli "iphuzu elifile" lokukhiya lendlela yokuvala isikhunta, kuyilapho indawo yokugcina ye-extrusion "indawo efile" yokumelana okuphezulu kwesikhunta.
