I-bumper yemoto ingenye yezesekeli ezinkulu emotweni, inemisebenzi emithathu eyinhloko: ukuphepha, ukusebenza nokuhlobisa.
Kunezindlela ezintathu eziyinhloko ze-car bumper lightweight: impahla engasindi, idizayini yokuthuthukisa izakhiwo kanye nokusungulwa kwenqubo yokukhiqiza.I-Material lightweight ngokuvamile ibhekisela ekushintsheni izinto zangempela ngaphansi kwezimo ezithile, njengepulasitiki yensimbi;i-bumper lightweight structure optimization design ikakhulukazi inobuchwepheshe bodonga oluncane;inqubo entsha yokukhiqiza ine-micro-foam kanye nokubumba okuyisiza kwegesi kanye nobunye ubuchwepheshe obusha.
Ipulasitiki yokukhetha impahla yepulasitiki ngenxa yekhwalithi yokukhanya, ukusebenza kahle kokusetshenziswa, ukukhiqiza okulula, ukumelana nokugqwala, ukumelana nomthelela, inkululeko yokuklama nezinye izici, isetshenziswa kabanzi embonini yezimoto, kanye nengxenye yezinto ezithe xaxa nangokwengeziwe embonini yezimoto.Inani lepulasitiki elisetshenziswa emotweni seliphenduke enye yezindlela zokukala izinga lokuthuthuka kwemboni yezimoto yezwe.Njengamanje, amazwe athuthukile ukukhiqiza imoto ezosetshenziswa ngepulasitiki isifinyelele ku-200kg, okuyisibalo esilinganiselwa ku-20% wekhwalithi yemoto.
Ipulasitiki embonini yezimoto yaseChina isetshenziswa sekwephuzile kakhulu, inani lepulasitiki ezimotweni ezingokomnotho lingama-50 ~ 60kg kuphela, izimoto ezindala zine-60 ~ 80kg, ezinye izimoto zingafinyelela ku-100kg, eChina ekukhiqizeni amaloli aphakathi nendawo, imoto ngayinye cishe 50kg plastic.Imoto ngayinye isebenzisa ipulasitiki amaphesenti angu-5 kuya kwangu-10 esisindo semoto.
Izinto zokwakha zebhampa ngokuvamile zinezidingo ezilandelayo: ukumelana nomthelela omuhle, ukumelana nesimo sezulu esihle.Ikhono elihle lokunamathisela ngopende, uketshezi oluhle, ukusebenza kahle kokucubungula, intengo ephansi.Ngakho-ke, izinto zekilasi le-PP ngokungangabazeki ziyinketho engcono eyongayo.Impahla ye-PP iwuhlobo lwepulasitiki oluvamile olusebenza kahle, kodwa i-PP ngokwayo inokushisa okuphansi okuphansi nokusebenza okuphansi nomthelela wokumelana, hhayi ukumelana nokugqoka, ukuguga okulula nokuqina kosayizi ompofu, ngakho-ke i-PP eguquliwe ivame ukusetshenziswa njengento yokukhiqiza ibhampa yemoto.Njengamanje, izinto ezikhethekile ze-polypropylene automotive bumper ngokuvamile ziyi-PP njengento eyinhloko, futhi yengeza ingxenye ethile yerabha noma i-elastomer, isigcwalisi esingaphili, izinhlayiya zikamama ezinombala, izithasiselo nezinye izinto ngemva kokuxutshwa nokucutshungulwa.
Kulula ukubangela i-warping deformation, okuwumphumela wokukhululwa kokucindezeleka kwangaphakathi.Obhampa abanezindonga ezincane babangela ingcindezi yangaphakathi ezigabeni ezihlukene zokubumba umjovo.
Ngokuvamile, kuhlanganisa ikakhulukazi ukucindezeleka kokuma, ukucindezeleka okushisayo kanye nokucindezeleka kokukhululwa kwesikhunta.Ingcindezi yokuma iwukukhanga kwangaphakathi okubangelwa imicu, amaketanga e-macromolecular noma izingxenye zamaketango ekuncibilikeni okuqondiswe endaweni ethile futhi okubangelwa ukuphumula okunganele.Umumo uhlobene nogqinsi lomkhiqizo, izinga lokushisa elincibilikayo, izinga lokushisa lesikhunta, ingcindezi yomjovo, nesikhathi sokugcina ingcindezi.Ukuphakama kobukhulu, kuyancipha ukuma;ukuphakama kwezinga lokushisa elincibilikayo, i-orientation ephansi, i-orientation ephansi;lapho umfutho womjovo uphezulu, kulapho i-orientation iphezulu khona;uma isikhathi sokugcina ingcindezi siba side, i-orientation inkulu.
Ukucindezeleka okushisayo kubangelwa izinga lokushisa eliphezulu lokushisa kwesikhunta kanye nezinga lokushisa eliphansi lesikhunta, kanye nezinga lokupholisa elisheshayo lokuncibilika endaweni eseduze nomgodi wokubumba.Ukucindezeleka kokukhululwa kubangelwa ikakhulukazi amandla anganele nokuqina kwesikhunta, ukuguqulwa kwe-elastic ngaphansi kwesenzo sokucindezela komjovo nokuphuma okuphezulu, kanye nokuhlelwa kokusabalalisa okungenangqondo komkhiqizo womkhiqizo akulingani.Udonga oluncane oluncane lungaba nzima.Ngenxa yokuthi i-gauge yokuqina kodonga incane futhi ine-shrinkage encane, umkhiqizo unamathele ngokuqinile ekubunjeni;ukulawulwa kwesikhathi sokubamba ingcindezi kunzima, futhi ukuqina kodonga oluncane nokuqinisa konakaliswa kalula.Ukuvulwa okujwayelekile kwesikhunta kudinga isirinji ukuze inikeze amandla okwanele okuvula isikhunta, okufanele sikwazi ukunqoba ukumelana nokuvula isikhunta.
Kunezithiyo eziningana okufanele zinqotshwe ohlelweni lokuvula isikhunta
Okokuqala, kuyadingeka ukunqoba amandla okuvulwa okuqondile.Lapho isikhunta sivulwa, ipulasitiki izoba namandla athile okunamathela ahambisana nesiqondiso sokuvula, okubangelwa ukupholisa izingxenye zepulasitiki lapho ukupholisa isikhunta kunganele, futhi ukunwetshwa okunwebekayo kohlobo lwe-cavity akutholakali ngokugcwele.Ubukhulu baleli gunya lokunamathela buhlobene nemvelo yepulasitiki, izinga eliphezulu lesikhunta, ukuthambekela kwesikhunta, njll. Ngaphezu kwalokho, kuyadingeka ukunqoba ukumelana nokuvula isikhunta esingaqondile, okungukuthi, uhlangothi lwemoto. core isizinda inqubo.Kuyadingeka futhi ukunqoba ukumelana nokungqubuzana okubangelwa ukunyakaza kwesifanekiso esinyakazayo sesikhunta kanye nesifanekiso somsebenzi.Khona-ke kuyadingeka ukunqoba ukucindezela kokubamba iqhaza kwe-cavity, lapho ukucindezela komgodi kungase kungalingani nokucindezela komkhathi, futhi ukucindezela emgodini akufani nokucindezela kwangaphandle.
Ukuze kuxazululwe izinkinga ezimbili ezinkulu ezingenhla, umklamo wesikhunta udinga ukuthuthukiswa ngendlela efanele.Khetha izinto ezifanele zokubumba ukuze uthuthukise amandla okushisa esikhunta nokumelana nokugqoka.Idizayini yesakhiwo sesikhunta esinengqondo kanye nokukhiqizwa, kwandise ngokufanele ukushuba kwepuleti eliphushayo kanye nepuleti lephedi eliphakathi, lithuthukise ukuqina kwesikhunta, linciphise ukuwohloka kokunwebeka kwesikhunta.Thuthukisa ukunemba kokukhiqiza nokudidiyela kwendlela yokukhipha ewumongo kanye nesistimu enyakazayo, wehlise ubulukhuni bohlobo lwesikhala, izakhi zemojuli ewumongo kanye ne-convex, futhi wehlise amandla okukhululwa kwesikhunta.Ngokudizayina okuphezulu nokunemba okufanayo, idivayisi yokuxhuma ivamise ukunikezwa ukuze kuvinjwe ukugudluzwa okuhlobene kwe-die core kanye ne-die cavity.Uhlelo lokuthela kufanele luklanywe ngendlela efanele, futhi umklamo wesiteshi sokugeleza kufanele usebenzise ngokweqile izingxenye zepulasitiki ukusuka ezindaweni eziwugqinsi ukuya ezindaweni ezincanyana ngesikhathi sokujova.Kuzodingeka futhi kube nezimbobo zokukhipha umoya ezanele.Mayelana nenqubo yomjovo, ukucindezeleka kwangaphakathi kwezingxenye zepulasitiki kufanele kuncishiswe, futhi isivinini somjovo kanye nesivinini sokupholisa kufanele sincishiswe.Ukwenyusa izinga lokushisa lokuncibilika kanye nezinga lokushisa lokukhunta kuyadingeka ukuze kukhululeke.Ukucindezelwa komjovo okunengqondo, isikhathi sokugcina ingcindezi, nesikhathi sokupholisa nakho kuyadingeka.I-Huangyan Leiao Molding Co., Ltd. itholakala edolobheni lase-Huangyan District mold, e-Taizhou, esifundazweni sase-Taizhou, “okuyindawo yokuzalwa yase-Chinese mold”.Le nkampani igxile kakhulu ekukhiqizeni isikhunta somjovo, inesipiliyoni seminyaka eminingi yesikhunta, ikakhulukazi ukukhiqiza kanye nokucutshungulwa kwesikhunta sombungu webhodlela, isikhunta sempahla ye-PET, isikhunta sesivalo sebhodlela, isikhunta semoto sangaphakathi kanye nesikhunta sokuhlobisa ngaphandle… … Isikhunta sinomklamo walo oyingqayizivele nobuchwepheshe bokucubungula, okusekelwe kumqondo othi "Ubuqotho bokuphathwa", namakhasimende asekhaya nakwamanye amazwe ukusungula ubudlelwano obuhle besikhathi eside sokubambisana, ngikholelwa ukuthi uLeiao uzobe ekufanele ukuthembela ekuhlanganyeleni. ibhizinisi.
