I-Warpage isho ukuphambuka kokuma komkhiqizo obunjiwe ngomjovo kusuka ekujuleni kwesikhunta. Kungokunye kokukhubazeka okuvamile kwemikhiqizo yepulasitiki. Kunezizathu eziningi ze-warpage ne-deformation, ezingenakuxazululwa ngamapharamitha wenqubo kuphela. Lokhu okulandelayo ukuhlaziywa okufishane kwezinto ezithinta i-warpage nokukhubazeka kwemikhiqizo ebunjiwe yomjovo.
Ithonya lesakhiwo sesikhunta kumkhiqizo we-warpage kanye nokusonteka.
Ngokuya ngesikhunta, izinto eziyinhloko ezithinta ukusonteka kwezingxenye zepulasitiki zithela uhlelo, uhlelo lokupholisa nohlelo lokukhipha.
(1) Uhlelo lokuthela.
Ukuma, ukwakheka nobuningi besango lomjovo womjovo kuzothinta isimo sokugcwaliswa kwepulasitiki embotsheni yesikhunta, okuholele ekuguqukeni komkhiqizo wepulasitiki. Uma ibanga lokugeleza lokuncibilika lide, kukhula ukucindezeleka kwangaphakathi okubangelwa ukugeleza nokondla phakathi kongqimba olufriziwe naphakathi kokugeleza kokugeleza; okufushane ibanga lokugeleza, kufushane isikhathi sokugeleza kusuka kokugudluza kuze kube sekupheleni kokugeleza komkhiqizo, kanye nobukhulu besendlalelo esiqhwaqhakala ngesikhathi sokugcwalisa isikhunta Ukuncipha, ukucindezeleka kwangaphakathi kuncishisiwe, nokuguqulwa kwe-warpage nakho kuzoncipha kakhulu. Kwezinye izingxenye zepulasitiki eziyisicaba, uma kusetshenziswa isango elilodwa kuphela, kungenxa yokuqondisa kobubanzi. Izinga lokuncipha kwe-BU likhulu kunezinga le-shrinkage ohlangothini oluzungezile, futhi izingxenye zepulasitiki ezibunjiwe zizokhubazeka; uma kusetshenziswa amasango amaphoyinti amaningi noma amasango ohlobo lwefilimu, ukusonteka okugoqekayo kungavinjelwa ngempumelelo. Lapho amasango wephoyinti asetshenziselwa ukubumba, futhi ngenxa ye-anisotropy yokuncipha kwepulasitiki, indawo nenombolo yamasango inethonya elikhulu ezingeni lokuguqulwa kwemikhiqizo yepulasitiki. Ngaphezu kwalokho. Ukusetshenziswa kokuguquguquka okuningi nakho kunganciphisa isilinganiso sokugeleza kwepulasitiki (L / t), ngaleyo ndlela kwenze ukuqina kokuncibilika emgodini kufane kakhulu futhi kunciphe umfaniswano owengeziwe. Ngemikhiqizo yonyaka, ngenxa yezimo ezihlukile zamasango, izinga elifanayo lomkhiqizo wokugcina nalo liyathinteka. Lapho wonke umkhiqizo wepulasitiki ungagcwaliswa ngaphansi kwengcindezi encane yomjovo, ingcindezi encane yomjovo inganciphisa ukuthambekela kokuma kwamangqamuzana epulasitiki futhi inciphise ukucindezela kwayo kwangaphakathi. Ngakho-ke, ukusonteka kwezingxenye zepulasitiki kungancishiswa.
(2) Ukupholisa uhlelo.
Ngesikhathi senqubo yokujova, izinga lokupholisa elingalingani lemikhiqizo yepulasitiki nalo lizothinta ukuncipha okungalingani kwezingxenye zepulasitiki. Lo mehluko ekunciphiseni kuholela ekwakhiweni kwezikhathi zokuguqa kanye ne-warpage yemikhiqizo. Uma umehluko wezinga lokushisa phakathi kwesikhunta somgogodla nomgogodla osetshenziswe ekubunjweni komjovo kwemikhiqizo eyisicaba (njengamagobolondo ebhethri efoni ephathekayo) mkhulu kakhulu, ukuncibilika okuseduze nomgodi obandayo wesikhunta kuzophola ngokushesha, kuyilapho impahla isondele isikhunta esishisayo imbobo Igobolondo lesendlalelo lizoqhubeka nokuncipha, futhi ukuncipha okungalingani kuzodala ukuthi umkhiqizo ugobe. Ngakho-ke, ukupholisa kwesikhunta somjovo kufanele kunake ibhalansi phakathi kwezinga lokushisa lomgogodla nomgogodla, futhi umehluko wokushisa phakathi kwalaba ababili akufanele ube mkhulu kakhulu (kulokhu, imishini yokushisa yesikhunta ingabhekwa).
Ngaphezu kokubheka ukushisa kwangaphakathi nangaphandle komkhiqizo kuvame ukulinganisela. Ukungaguquguquki kokushisa ohlangothini ngalunye kufanele kubhekwe nakho, okungukuthi, izinga lokushisa lomgodi kanye nomgogodla kufanele kugcinwe ngokufana ngangokunokwenzeka lapho isikhunta selehlile, ukuze izinga lokupholisa lezingxenye zepulasitiki likwazi ukulinganiswa, ukuze ukuncipha kwezingxenye ezahlukahlukene kufana kakhulu futhi kusebenza ngempumelelo ukuvimbela ukusonteka. Ngakho-ke, ukuhleleka kwezimbobo zamanzi ezipholisayo kusikhunta kubaluleke kakhulu, kufaka phakathi ukupholisa imbobo yamanzi ububanzi d, isikhala somgodi wamanzi b, udonga lwamapayipi kubanga elingaphezulu c nobubanzi bomkhiqizo w. Ngemuva kokunqunywa kwebanga phakathi kodonga lwamapayipi nobuso bomgodi, ibanga phakathi kwezimbobo zamanzi okupholisa kufanele libe lincane ngangokunokwenzeka. Ukuze kuqinisekiswe ukufana kwezinga lokushisa lodonga lwenjoloba olubunjiwe; inkinga okufanele inakwe lapho kunqunywa ubukhulu bomgodi wamanzi opholile ukuthi noma ngabe isikhunta sikhulu kangakanani, ububanzi bomgodi wamanzi abunakuba ngaphezu kuka-14mm, uma kungenjalo isiphephetha ngeke sakha ukugeleza okunesiyaluyalu. Ngokuvamile, ububanzi bomgodi wamanzi bunganqunywa ngokuya ngosayizi odongeni womkhiqizo, lapho ubukhulu bodonga obungu-2mm. Ububanzi bomgodi wamanzi bungu-8-10mm; lapho ubukhulu bodonga obungu-2-4mm, ububanzi bomgodi wamanzi ngu-10-12mm; lapho ubukhulu bodonga obungu-4-6mm, ubukhulu bomgodi wamanzi bungu-10-14mm, njengoba kukhonjisiwe kuMdwebo 4-3 Kukhonjisiwe. Ngasikhathi sinye, njengoba izinga lokushisa lendawo yokupholisa likhuphuka ngokukhuphuka kobude besiteshi samanzi sokupholisa, umehluko wezinga lokushisa phakathi komgodi nengqikithi yesikhunta wenziwa eduze komsele wamanzi. Ngakho-ke, ubude besiteshi samanzi wesifunda ngasinye sokupholisa kudingeka bube ngaphansi kuka-2m. Amasekethe amaningi okupholisa kufanele afakwe kwisikhunta esikhulu, futhi ukungena kwesekethe eyodwa kutholakala eduze kwesitolo sesinye isifunda. Ezingxenyeni zepulasitiki ezinde, kufanele kusetshenziswe iziteshi zamanzi eziqonde ngqo. Iningi lezikhunta zethu zamanje zisebenzisa izihibe ezimise okwe-S, ezingakulungeli ukusakazwa nokwandisa umjikelezo.
(3) Uhlelo lokukhipha.
Idizayini yohlelo lwe-ejector nayo ithinta ngqo ukusonteka kwemikhiqizo yepulasitiki. Uma uhlelo lokukhipha lungalingani, kuzodala ukungalingani emandleni okukhipha futhi kukhubaze umkhiqizo wepulasitiki. Ngakho-ke, lapho kuklanywa uhlelo lokukhipha, amandla okukhipha kufanele alinganiswe nokuphikiswa kokukhishwa. Ngaphezu kwalokho, indawo enqamulelayo yenduku ye-ejector ayinakuba ncane kakhulu ukuvimbela umkhiqizo wepulasitiki ukuthi ungakhubazeki ngenxa yamandla amaningi ngokweyunithi yendawo (ikakhulukazi lapho izinga lokushisa elidilizayo liphezulu). Ukuhlelwa kwenduku ye-ejector kufanele kusondele ngangokunokwenzeka engxenyeni enokumelana okuphezulu kokubuyisa. Ngesisekelo sokungaphazamisi ikhwalithi yemikhiqizo yepulasitiki (kufaka phakathi izidingo zokusetshenziswa, ukunemba okulinganayo, ukubukeka, njll.), Izinto eziningi ngangokunokwenzeka kufanele zisethelwe ukunciphisa ukushiyeka okuphelele kwemikhiqizo yepulasitiki (lesi yisizathu sokushintsha induku ephezulu kubhuloki ephezulu).
Lapho kusetshenziswa amapulasitiki athambile (njenge-TPU) ukukhiqiza izingxenye zepulasitiki ezinamapulangwe amancane anezindonga ezijulile, ngenxa yokumelana nokudilizwa okukhulu nezinto zokwakha ezithambile, uma nje kusetshenziswa indlela eyodwa yokukhipha imishini, imikhiqizo yepulasitiki izokhubazeka. Ngisho nokugqoka noma ukusonga okuphezulu kudala ukuthi imikhiqizo yepulasitiki isuswe. Kulokhu, kuzoba ngcono ukushintshela enhlanganisweni yezakhi eziningi noma inhlanganisela yengcindezi yegesi (i-hydraulic) kanye nokukhishwa kwemishini.
