Ukuhlaziywa kokusebenza kwesikhunta sokufa okufa-sokuxhuma kwepuleti ezintathu

Ukuhlaziywa kwenqubo yokuphonsa kanye nokuklanywa kokubumba kwe-ZL103 Alloy Bracket

Umdwebo 1 ukhombisa umdwebo wesakhiwo sengxenye yeBracket, eyenziwe nge-ZL103 Alloy. Ubulukhuni besimo sengxenye, ukuba khona kwezimbobo eziningi, nobukhulu bayo obuncane kwenza kube nzima ukukhipha ngesikhathi senqubo yokuphonsa futhi kungaholela ezindabeni zokubekezelelana kwezimo kanye nezici. Njengoba kunikezwe ukunemba okunempilo okuphezulu kanye nezidingo ezisezingeni eliphezulu, kubalulekile ukubheka ngokucophelela indlela yokudla, ukondla isikhundla, kanye nokuma kwengxenye ekwakhiweni kokubumba.

Isakhiwo Sobumbi Esikhuthazayo Esibulawe, njengoba kukhonjisiwe kuMfanekiso 2, kulandela ukwakheka kohlobo lwepuleti amathathu nomugqa ohlukanisayo onamanani amabili. Isikhungo siphakela eSangweni Lephuzu, sinikeza umphumela obanelisayo kanye nokubukeka okuhle kakhulu.

Ifomu lokuqala lesango elikhethelwe isikhunta sokufa se-Dies kwakuyisango eliqondile. Kodwa-ke, kwaqashelwa ukuthi indawo yokuxhumana phakathi kwezinto eziseleyo kanye nokusakaza kwakuyinto enkulu ngemuva kwengxenye yokwakhiwa kwengxenye, okwenza kube yinselele ukususa impahla eyabekelayo. Ukuba khona kokudla okusele okunomthelela omubi kwekhwalithi yendawo engenhla yokuphonsa, okubangela ama-hinsage emithanjeni engazange ihlangabezane nezidingo zokuphonsa. Ukubhekana nalokhu, kwamukelwa isango lokuthola amaphuzu futhi kwabonakala ukuthi kusebenza kahle ekukhiqizeni imali enezindawo ezibushelelezi kanye nezakhiwo zangaphakathi ezifanayo. Isango elingaphakathi linqunywe njengo-2mm, futhi kwasetshenziswa inguquko H7 / m6 phakathi kwesango elihlaselayo 21 kanye neplate elungisiwe yokubumba ipuleti 22. Ingaphakathi lesango elibusheni lalihlehliswa ukwenza lula ukuhlukaniswa kwe-condensate esiteshini esikhulu, ukufeza ubulukhuni be-ra = 0.8μm.

Uma kucatshangelwa ukulinganiselwa okubangelwa ukwakheka kohlelo lwe-ging, kwaqashwa khona indlela yokudlela emibili ebusweni ukubhekana nokuhlukaniswa okuyingxenye kusuka endaweni evuthayo kanye nendawo yokuphonsa. Indawo ehlukanisayo engangisetshenziselwa ukuhlukanisa impahla esele ivela esikhwameni se-sprue, kuyilapho ehlukanisa ingaphezulu kwe-II yephule impahla esele kusukela endaweni yokuphonsa. Iplate exakile 24, etholakala ekugcineni kwenduku engama-23, ihambise ukuhlukaniswa okulandelanayo kwezindawo ezimbili zokuhlukanisa. Ngaphezu kwalokho, induku ye-tie 23 isebenza njenge-fixer yebanga. Ubude bomsindo womlomo benzelwe ukunciphisa ukususwa kwezinto ezisele.

Ngemuva kokuhlukana, okuthunyelwe komhlahlandlela kuvela emgodini wemihlahlandlela yethempulethi eshukumisekayo 29. Ngenxa yalokho, ngesikhathi sokuvalwa isikhunta, i-mold cavity Insert 26 ibeka kahle i-nylon plunger 27 kwithempulethi eshukumekayo 29.

Idizayini yokuqala yokubumba ifake i-push-yesikhathi esisodwa isebenzisa induku yokucindezela. Kodwa-ke, lokhu kwaholela ezinkingeni ezinjengokonakaliso nosayizi ngaphandle kokubekezelelana ngokukhokhiswa. Ucwaningo olunzulu nokuhlola kwembulwa ukuthi ubukhulu obuncane nobude bama-caring baphumela emandleni akhulayo akhuphuke enkabeni yokufaka isikhunta esishukumisayo, okuholela ekuguqukeni kwamandla ashukumisayo kuwo womabili ama-Exs. Ukuxazulula le nkinga, kwaqaliswa inqubo yesibili yokucindezela. Le ndlela isebenzise isakhiwo sokuxhumeka kwe-hinge, lapho ipuleti lokucindezela olungenhla lwe-8 ne-push Plate engu-12 lixhunywe ngamapuleti amabili ama-hinge 9 no-10 no-pin shaft 14. Amandla okucindezela avela endodeni ye-die-casting machin's Push Favod yaqedwa ekuqaleni kwepuleti engu-8, inika amandla ukunyakaza okukodwa kokuqala kwe-push yokuqala. Lapho umkhawulo womkhawulo we-Limit Block block 15 wedlulile, i-hinge egobekile, namandla aqhamuka e-Die-Casting Machine's Push Rod enza kuphela epuletini eliphansi le-12. Ngalesi sikhathi, ipuleti elingenhla le-8 lamisa ukuhamba, ukuvumela ukucindezela kwesibili.

Inqubo yokusebenza yoMuld ifaka umjovo osheshayo we-alloy ewuketshezi ngaphansi kwengcindezi evela emshinini wokudla, olandelwa ukuvulwa kobumba ngemuva kokuqala ukwakha. Ngesikhathi sokuvula isikhunta, i-I-I Fort ebusweni ekuqaleni yahlukaniswa, ivumela ukwahlukaniswa kwezinto ezisele esangweni elivela esikhwameni se-Sprue 21. Kamuva, njengoba isikhunta siyaqhubeka nokuvula, izinduku zengxabano 23 zithinta ukuhlukaniswa kwendawo yokuhlukanisa ii, ukudonsa okuseleyo okusele kusuka ku-IMATE. Ucezu lonke lwezinto ezisetshenzisiwe lungasuswa ekufakweni kwesikhungo kwesikhunta esinqunyelwe. Indlela ye-Ejection yasungulwa, iqala ukucindezela kokuqala. Ipuleti eliphansi le-hinge 10, i-pin shaft 14, neplate ephezulu ye-hinge 9 vumela induku ye-push ye-push yomshini wokudla ukuze ucindezele ipuleti eliphansi le-12 ne-upping it itrate of the 3 ngenkathi usebenze ukudonsa okungu-5 kokufakwa komnyombo wokufaka okungu-5. Njengoba i-PIN shaft 14 ihamba kude ne-Limit Block 15, igoba ibheke enkabeni yesikhunta, okuholela ekulahlekelweni kwamandla ngepuleti ephezulu 8. Ngenxa yalokho, i-bolt push induku engu-18 futhi icindezele ipuleti 2 yeka ukuhamba, ngenkathi ipuleti eliphansi le-12 liqhubeka nokuqhubekela phambili, licindezele i-turner tube 6 ukuhambisa umkhiqizo ngaphandle komkhiqizo wepuleti 2. Indlela ye-Ejection isethwe kabusha esimweni sayo sokuqala ngesikhathi sokuvalwa isikhunta, uqedela umjikelezo osebenzayo owodwa.

Ngesikhathi sokusetshenziswa kokubumba, ingaphezulu lokukhonkotha kuboniswe i-mesh burr eyandisiwe njengoba inani lemijikelezo yokulahla efe. Ucwaningo lwembulwe izimbangela ezimbili zalolu daba: Umehluko omkhulu wokushisa wokulwa nokungezwani okukhulu kwe-cavity ubulukhuni. Ukunciphisa lezi zinkinga, ukucisha kuqala isikhunta ngaphambi kokusetshenziswa kanye nokusebenzisa ukupholisa ngesikhathi sokukhiqiza kubalulekile. Isikhunta sishaywa kusethwa ngaphambi kokushisa kuka-180 ° C, futhi ubulukhuni be-mold cavity cavity lulawulwa, buyigcina eRa≤0.4μm. Lezi zinyathelo zithuthukisa kakhulu ikhwalithi ye-castings.

Ubuso besilisa buthola ukwelashwa kwe-nitriding ukwenza ngcono ukumelana kokugqoka, futhi ukusatshalaliswa komnotho okufanele nokupholisa kuyaqinisekiswa ngesikhathi sokusebenzisa. Ngaphezu kwalokho, ukufutheka kwengcindezi kwenziwa ngemuva kwayo yonke imijikelezo eyi-10,000 yokufa okufayo, futhi ingaphezulu le-cavity libunjiwe futhi lingenani. Lezi zinyathelo zinwebeka kakhulu isikhathi sokuphila kwesikhutha. Njengamanje, isikhunta sedlule imijikelezo engu-50 000 yokufa, okubonisa ukuthembeka kwayo nokuqina kwayo.

Ekuphetheni, ukuhlaziywa kwenqubo yokuphonsa kanye ne-Mold Design ye-ZL103 Alloy Bracket iqokomisa ukubaluleka kokucabanga ngezinto ezifana nendlela yokudla kanye nekhwalithi ephezulu. Isango elikhethiwe, isango le-Point, libonakalise lisebenza kahle ekukhiqizeni izinkulungwane ezinezindawo ezibushelelezi nezinhlaka zomfaniswano. Umshini wokuhlukanisa izingxenye ezimbili, eceleni komklamo we-hinge-based push-out design, izingqinamba ezixazululiwe ezihlobene nokuguquguquka nosayizi ngaphandle kokubekezelelana ngokukhokhiswa. Ngemuva kokuzibusisa okulungile kobumbano, okulawulwa yi-cavity cavity ubulukhuni, kanye nezindlela zokuvimbela ezinjengeNitriding, ukufutheka, nokuphoqelela, isikhunta esinesikhathi sokuphila esinempilo kanye nekhwalithi ethuthukisiwe yokuphonsa. Impumelelo yale projekthi ibonisa ukuzibophezela kukaTarsen kwikhwalithi nokwakhiwa okusha.
