1, Uyilo lwangaphambi kokuguqulwa lubalulekile

Malunga ne-auto air & water tank product mold, ulawulo lomgangatho woyilo kunye nokuveliswa kunzima kunohlobo oluqhelekileyo, njengoko olu hlobo lwezixhobo ludla ngokubunjwa yi-PA6 (PA66) + GF (30-35%) compound, kwaye olu hlobo lwezixhobo kulula ukulufumana deformation ngexesha lenkqubo yokubumba, kwaye ubungakanani bemveliso obuhambelanayo kulula ukuba bunganyamezeleki. Ke ngoko, xa uqhelene ne-deformation yayo rhoqo, emva koko ukwenza uyilo lwangaphambi kokuguqulwa ngokusekelwe kumava kunye nohlalutyo lwe-CAE kukhokelela kwinkqubo yoyilo lwasekuqaleni ibe sisitshixo sempumelelo yokwenziwa kwe-mold.

Iqela le-mold lase-Enuo linamava angaphezu kweminyaka eli-10 ekwenzeni i-mold ngaphambi kokuguqulwa, kwaye liye lakhonza abathengi be-Valeo, Mahle-behr, Delphi kunye nabanye abathengi bezixhobo zeemoto abadumileyo kwihlabathi liphela. Apha sazisa ngokufutshane amava ethu okwenza i-mold yomoya kunye ne-tank yamanzi. Ngokuqinisekileyo, iinkampani ezahlukeneyo zineendlela ezahlukeneyo, ukuba mfundi othandekayo unembono ezahlukeneyo, wamkelekile ukuba unxibelelane nathi.

2, Ukuhlalutya imizobo yeendawo, ukucacisa iindawo ezibalulekileyo zemveliso kunye nobukhulu bayo

Ukuqonda iindawo ezibalulekileyo zemveliso kunye nobukhulu obuhambelanayo buhlala buyinto yokuqala xa imizobo yemveliso yabathengi ifika, ke nikela ingqalelo engakumbi kwezo zinto zibalulekileyo, ezifana nemveliso ethi "Umphezulu wokugqibela" ("Umphezulu wokugqibela" wawufuneka ngokuthe ngqo, ukuthamba kunye nokunyamezelana kobungakanani befom, kwaye ezinye iindawo zobukhulu bemveliso ziya kulandela ukutshintsha kwazo) "Indawo ye-Tube orifice" (ubukhulu be-"tube orifice" nayo ibaluleke kakhulu, ngokuqhelekileyo kufuneka indawo, ukunyamezelana kwesilinda kunye nobukhulu) kunye neembambo zemveliso ethi "Boss" kunye "no-U-shape" njl.njl., ziboniswe ngezantsi:

Kwisikhunta esitsha, yenza i-pre-deformation kwimveliso (ukwenza "imbuyekezo yezinto ezibonakalayo" kwicala elichaseneyo lokuguqulwa okuqikelelweyo kwangaphambili ngokwemava kunye nohlalutyo lwe-CAE, cebisa ukuba zilungiswe emva kokuba kwenziwe i-deformation yokwenyani). Emva kovavanyo lwesikhunta, wenze utshintsho oluncinci olusekelwe kwi-deformation yokwenyani yokubunjwa kwemveliso, ukulungisa i-geometry yeplastiki, imo kunye nendawo njalo njalo.

3, Ukuzoba iimveliso.

Ukuze kube lula ukwenza ngcono isikhunta kwixesha elizayo, kufuneka sizitsalele idatha entsha yemveliso ye-3D ngokwemveliso yomthengi (iiparameter ezibalulekileyo kufuneka zigcinwe). Ukuchonga ixabiso lokuguqulwa kwemveliso, kunye nohlalutyo lokuhamba kwesikhunta kunye namava okuguqula idatha yemveliso, ngezantsi ungabona iindlela zokuguqulwa ezinamava:

Apha, amanye amacebiso ayavuya ukwabelana ngawo ngexesha lenkqubo yokuzoba kwakhona, anje ngala: soloko uqala ekuzobeni indawo "yomphezulu wesiphelo sesiseko", ngokwexabiso lokuguqulwa ukuze uzobe ukuthe tye, ijika elithe tyaba kumphetho wemveliso, bhekisa kwezo jika ukuya kumphezulu "wokolula" (umyalelo we-UG). Imiphezulu ethe tyaba yenziwa ngomyalelo we-"Border" (umyalelo we-UG). Eli nyathelo libalulekile, ukuze kube lula ukutshintsha kwixesha elizayo, zoba ijika kuqala, ungasoluli umphezulu "wokolula" (umyalelo we-UG) ngokuthe ngqo, uze usebenzise umphezulu wokuguqulwa kokuqina ufumane imo yemveliso ngomyalelo we-"Offset" (umyalelo we-UG). Ukuze uphephe ukutshintsha iindawo ezininzi zesikhunta ngexesha lokulungisa isikhunta esilandelayo, yenza ukusika izinto zeplastiki kwindawo "yomphezulu wesiphelo sesiseko" semveliso, uze uzibuyisele kwakhona kutshintsho lwe-T1-T3 ngokusekelwe kukuguqulwa kwemveliso yokwenyani (kunye neplastiki).

Iingcebiso ze-paybe eziluncedo:

1. Musa ukukopa umphezulu weprofayili yeemveliso zabathengi kangangoko kunokwenzeka, zama ukuzizoba ngokwenu. Ukuze, ngenxa yotshintsho lwe-mold olulandelayo kube lula ukutshintsha, kuquka nobukhulu bodonga. Ukuba iimilo zikopishwe kwimveliso yabathengi emva kotshintsho oluninzi, idatha ye-3D iya kufumana ukuphazamiseka.
2. Kwinkqubo yokuzoba, jonga idatha yemveliso ye-2/3D yomthengi kangangoko kunokwenzeka ukuze uthintele ukuba yahlukile.

4, Umkhwa onokwenzeka wokuguquguquka malunga nenxalenye ebalulekileyo yemveliso

1, Ukuguqulwa kwemveliso "Umphezulu wesiphelo sesiseko"

Kangangoko kunokwenzeka ukunciphisa isenzo kwizinto zeplastiki ekuqaleni, kunokuthintela ukuphinda kwenziwe iindawo zokubumba kangangoko kunokwenzeka. Umgca obomvu ongezantsi ubonisa indlela eqikelelweyo yokuguqulwa kwemveliso. Nceda uqaphele ukuba iimbambo "zeBoss" okanye "ezimile njengo-U" okanye izinto ezinxulumene nazo kufuneka zihanjiswe kunye "nomphezulu wesiphelo sesiseko" (Ezinye zezinto eziphantsi kweboss ziyehla nge-0.5mm, emva koko "iBoss" nayo iyehla nge-0.5), uze uzobe ezinye. Kucetyiswa ukuba usebenzise "umphezulu" (umyalelo we-UG) ukuzizoba.

2, Ukuguqulwa kwemveliso "ye-Tube orifice"

Imilo yeradiyo "R" engcanjini yetyhubhu kufuneka ifane ncakasana nedatha yemveliso yabathengi, njengoko le radiyo "R" ichaphazela amandla endawo ebalulekileyo yemveliso. Kwiimeko eziqhelekileyo, ityhubhu engqukuva kufuneka incitshiswe iplastiki ecaleni kuqala, emva koko itshintshe ixabiso ngokwenguquko yokwenyani, kwityhubhu enkulu, imilo yetyhubhu mhlawumbi yenzelwe ukuba ibe yimo ye-oval kwangaphambili.

3, imveliso "U" iplastiki deformation bit

Iplastiki “enemilo ye-U” nayo kufuneka yenze malunga nokuguquguquka kweedigri ezingama-2-3, indawo ephakathi yeembambo “enemilo ye-U” kufuneka yenze ukusika izinto ecaleni (umfanekiso 1). Emva kokuba zonke iimveliso zidwetshwe kakuhle kwaye emva koko uyile i-radius “R” (kwakhona ukuze kube lula ukutshintsha, ngamanye amaxesha ukwakhiwa kwakhona kwe-radius “R” kuya kusilela okanye kuchithe ixesha elide), ukuba ezinye iijometri kwidatha yabathengi ye-3D azizange zitshintshe, singazitshintsha ukuba azichaphazeli ukuhlanganiswa kweendawo (uninzi lwabathengi lukhetha ukuba imilo ebukhali ixutywe ne-radius “R”. Ukongeza, ezinye iijometri ezibonakalayo emzimbeni oyintloko wemveliso zikhulu, olu hlobo lokuguquguquka kwemveliso kufuneka lunike ingqalelo ngakumbi kwi-parallelism kunye ne-perpendicularity (umfanekiso 2).

5, Isiphelo

Ngasentla ngamava ethu ekuyileni i-auto air & water tank - "elula deformation". Ukugqiba eli nyathelo kulungile, ndicinga ukuba isiqingatha sempumelelo yokwenziwa kwe-molds ezinjalo besingayi kuyifumana, ngoko ke siphi esinye isiqingatha? nceda ujonge icandelo elilandelayo leli nqaku elithi "Ngaba uyazi indlela yokwenza i-pre-deformation mold?" kwiveki ezayo.
Kulungile, bafundi abathandekayo. Enkosi kakhulu ngexesha lenu lokufunda apha. Ndilangazelela ukunibona kwicandelo elilandelayo!
