(1) Isakhiwo somshini wokubumba umjovo
Umshini wokubumba umjovo uvame ukwenziwa ngohlelo lokujova, uhlelo lokunamathela, uhlelo lokuhambisa u-hydraulic, uhlelo lokulawula ugesi, uhlelo lokuthambisa, uhlelo lokushisa nokupholisa, kanye nohlelo lokuqapha ukuphepha.
1. Uhlelo lokujova
Indima yesistimu yomjovo: uhlelo lokujova lungenye yezinto ezibaluleke kakhulu kumshini wokubumba umjovo, ngokuvamile kufaka phakathi uhlobo lwe-plunger, uhlobo lwe-screw, isikulufa se-plunger pre-plastic
Izinhlobo ezintathu eziyinhloko zokudubula. Uhlobo lwesikulufa njengamanje lusetshenziswa kakhulu. Umsebenzi wawo ukuthi kumjikelezo womshini wokujova epulasitiki, inani elithile lepulasitiki lingashiswa futhi lifakwe iplastikhi ngesikhathi esinqunyiwe, futhi ipulasitiki encibilikisiwe ingafakwa emgodini wesikhunta ngesikulufa ngaphansi kwengcindezi ethile nejubane. Ngemuva komjovo, into encibilikisiwe efakwe kulomgodi igcinwa isesimweni.
Ukwakheka kohlelo lokujova: Uhlelo lokujova luqukethe idivayisi yeplastikhi nedivayisi yokudlulisa amandla. Idivayisi yokufaka ipulasitiki yomshini wokubumba umjovo wesikulufu ikakhulukazi yakhiwe ngedivayisi yokuphakela, umgqomo, isikulufa, ingxenye yenjoloba kanye nombhobho. Idivayisi yokudlulisa amandla ifaka isilinda kawoyela womjovo, isihlalo somjovo esihambisa isilinda samafutha nedivayisi ye-screw drive (imoto encibilikayo).
2. Isikhunta clamping uhlelo
Indima yohlelo lokuminyanisa: indima yohlelo lokuqiniswa ukuqinisekisa ukuthi isikhunta sivaliwe, savulwa futhi sakhishwa imikhiqizo. Ngasikhathi sinye, ngemuva kokuthi isikhunta sivaliwe, amandla anele okubambelela anikezwa isikhunta ukumelana nengcindezi yomgodi eyenziwe ngopulasitiki oncibilikisiwe ongena emgodini wesikhunta, futhi uvimbele isikhunta ekuvuleni izintambo, okuholela esimweni esibi somkhiqizo .
3. Uhlelo lwe-Hydraulic
Umsebenzi wohlelo lokudlulisela umfutholuketshezi ukuqaphela umshini wokubumba umjovo wokuhlinzeka amandla ngokuya ngezenzo ezahlukahlukene ezidingekayo ngenqubo, nokuhlangabezana nezidingo zengcindezi, isivinini, izinga lokushisa, njll. umshini. It is ikakhulukazi yakhiwa izingxenye ezehlukene wokubacindezela kanye izingxenye wokubacindezela wokubasiza, phakathi kwawo futha uwoyela futhi motor kukhona imithombo amandla umshini umjovo udini. Ama-valve ahlukahlukene alawula umfutho kawoyela nokugeleza kwawo ukuhlangabezana nezidingo zenqubo yokubumba umjovo.
4. Ukulawulwa kagesi
Uhlelo lokulawula ugesi nohlelo lwe-hydraulic luhlanganiswe ngokufanelekile ukufeza izidingo zenqubo (ingcindezi, izinga lokushisa, isivinini, isikhathi) nokuhlukahluka
Isenzo sohlelo. Ngokuyinhloko yakhiwe ngogesi, izinto zikagesi, amamitha, ama-heater, izinzwa, njll. Ngokuvamile kunezindlela ezine zokulawula, ezenziwa ngesandla, ezizenzekelayo, ezizenzekelayo ngokuphelele, nezokulungiswa.
5. Ukushisa / ukupholisa
Uhlelo lokushisa lusetshenziselwa ukufudumeza umgqomo nombhobho womjovo. Umgqomo womshini wokubumba umjovo ngokuvamile usebenzisa iringi yokushisa kagesi njengethuluzi lokushisa, elifakwe ngaphandle komgqomo futhi litholwa ngezigaba yi-thermocouple. Ukushisa kuqhuba ukuqhutshwa kokushisa ngodonga lwe-cylinder ukuhlinzeka ngomthombo wokushisa we-plasticization yento; uhlelo lokupholisa lusetshenziswa kakhulu ukupholisa izinga lokushisa likawoyela. Ukushisa ngokweqile kukawoyela kuzodala amaphutha ahlukahlukene, ngakho-ke izinga lokushisa likawoyela kufanele lilawulwe. Enye indawo edinga ukupholiswa iseduze nechweba lokondla lepayipi lokuphakela ukuvimbela ukuthi impahla eluhlaza ingancibiliki echwebeni lokuphakela, okwenza ukuthi impahla eluhlaza yehluleke ukondliwa ngokujwayelekile.
6. Uhlelo Lubrication
Uhlelo lokuthambisa isekethe elihlinzeka ngezimo zokugcotshwa kwezingxenye ezihambisanayo zesifanekiso somshini wokubumba umjovo, umshini wokulungisa isikhunta, ukuxhuma umshini wenduku, itafula lomjovo, njll, ukuze kunciphise ukusetshenziswa kwamandla futhi kwandise impilo yezingxenye . Ukumanzisa kungaba ukuthambisa okuvamile kwemanuwali. Kungaba futhi ukuthambisa okuzenzakalelayo kagesi;
7. Ukuqapha ukuphepha
Idivayisi yokuphepha yomshini wokubumba umjovo isetshenziswa ikakhulukazi ukuvikela ukuphepha kwabantu nemishini. Yakhiwe ngomnyango wokuphepha, ukudideka kwezokuphepha, i-valve yokubacindezela, iswishi yomkhawulo, into yokutholwa kwe-photoelectric, njll.
Uhlelo lokuqapha ikakhulukazi luhlola ukushisa kukawoyela, ukushisa kwempahla, ukulayishwa kwesistimu, nokwehluleka kwenqubo kanye nemishini yomshini wokubumba umjovo, futhi kukhombisa noma ama-alamu lapho kutholakala izimo ezingavamile.
(2) Ukusebenza isimiso somjovo udini umshini
Umshini umjovo udini kuyinto ekhethekile plastic udini umshini. Isebenzisa i-thermoplasticity yepulasitiki. Ngemuva kokuthi ishisiwe futhi incibilike, ithululelwa ngokushesha embotsheni yesikhunta ngokucindezela okukhulu. Ngemuva kwesikhathi sengcindezi nokupholisa, iba ngumkhiqizo wepulasitiki wezimo ezahlukahlukene.
