1, Idizayini ye-pre-deformation iyisihluthulelo

Mayelana nesikhunta sepulasitiki somoya we-auto & ithangi lamanzi, ukulawulwa kwekhwalithi yomklamo nokukhiqiza kunzima kakhulu kunohlobo olujwayelekile, njengoba lolu hlobo lwezingxenye luvame ukubunjwa yi-PA6 (PA66) + GF (30-35%) kwakwakhe, futhi lokhu uhlobo impahla kulula ukuthola deformation ngesikhathi inqubo ukubumba, futhi usayizi ohambelana umkhiqizo kulula kube out of ukubekezelelana. Ngakho-ke, ukujwayelana nokuguquguquka kwayo okujwayelekile, bese ukwenza umklamo wangaphambi kokuguqulwa ngokusekelwe kokuhlangenwe nakho kanye nomphumela wokuhlaziywa kwe-CAE enqubweni yokuqala yokuklama kube yisihluthulelo sempumelelo yokukhiqiza isikhunta.

Ithimba le-Enuo mold linesipiliyoni seminyaka engaphezu kweyi-10 ekwenzeni isikhunta sangaphambi kokuguqulwa, futhi likhonze i-Valeo, i-Mahle-behr, i-Delphi namanye amakhasimende adumile emhlabeni wezingxenye zezimoto. Lapha sethula kafushane okuhlangenwe nakho kwethu ekwenzeni isikhunta somoya ozenzakalelayo nethangi lamanzi. Ngokuqinisekile, izinkampani ezahlukene zinemikhuba ehlukene, uma umfundi othandekayo enemibono ehlukene, futhi wamukelekile ngokufudumele ukuxhumana nathi.

2, Ukuhlaziya imidwebo yezingxenye, cacisa izindawo ezibalulekile zomkhiqizo nosayizi

Ukuze uqonde izindawo ezibalulekile zomkhiqizo kanye nosayizi abakhulu abahlotshaniswayo kuhlale kuyisinyathelo sokuqala lapho imidwebo yomkhiqizo wamakhasimende ifika, bese unaka kakhulu lokho kubaluleka, njengomkhiqizo othi “End surface” (“Indawo yokuphela” yayidingeka ubuqotho obuqinile, ukucaba. nokubekezelela usayizi wefomu, nezinye izingxenye zobukhulu bomkhiqizo zizolandela ukushintsha kwazo),"indawo ye-Tube orifice" (ubukhulu be-"tube orifice" bubaluleke kakhulu, ngokuvamile ukuma, ukubekezelelana kwe-cylindrical kanye ne-dimensional kuyadingeka) kanye nomkhiqizo " Izimbambo ze-Boss kanye “ne-U-shape” njll., ziboniswa ngezansi:

Ukuze uthole isikhunta esisha, yenza i-pre-deformation emkhiqizweni (ukwenza "isinxephezelo sezinto ezibonakalayo" ngakolunye uhlangothi lwe-deformation elinganisiwe kusengaphambili ngokusho kokuhlangenwe nakho nokuhlaziywa kwe-CAE, phakamisa ukubenza balungise ngemva kokwenziwa kokuguqulwa kwangempela). Ngemuva kokuhlolwa kwesikhunta, ukwenza ukuguqulwa okuncane okusekelwe ekuguqulweni kwangempela kokubunjwa komkhiqizo, ukulungisa i-geometry yepulasitiki, ukuma nokuma nokunye.

3, Ukudweba imikhiqizo.

Ukuze kube lula ukuthuthukiswa kwesikhunta esizayo, ukudweba idatha yomkhiqizo omusha we-3D ngokwethu kuyadingeka ngokomkhiqizo wekhasimende kuyadingeka (imingcele ebalulekile kufanele igcinwe). Ukunquma inani lokuguqulwa kwemikhiqizo, kuhlanganiswe nokuhlaziywa kokugeleza kwesikhunta kanye nolwazi ukuze ulungise idatha yomkhiqizo, ngezansi ungabona amathrendi anolwazi lokuwohloka:

Lapha, amanye amathiphu ajabulela ukwabiwa ngesikhathi senqubo yokudweba kabusha, njengokuthi: njalo qala ekudwebeni indawo “yesisekelo sokuphela”, ngokwenani lokuguquguquka ukuze udwebe ubuqotho, ijika eliyisicaba emaphethelweni omkhiqizo, bhekisela kulawo majika. ukuze "Yelula"(umyalo we-UG) endaweni eqondile. Izindawo eziphansi zenziwa “ngomngcele” (umyalo we-UG). Lesi sinyathelo sibalulekile, ukuze kube lula izinguquko zesikhathi esizayo, dweba ijika kuqala, "ungayeluli" (umyalo we-UG) ngokuqondile, bese usebenzisa indawo eguquguqukayo yokuqondisa thola umumo womkhiqizo ngokuthi "Offset" (umyalo we-UG). Ukuze ugweme ukushintsha izingxenye eziningi zesikhunta ngesikhathi sokuthuthukisa isikhunta esilandelayo, ukwenza izinto zepulasitiki zokusika endaweni yomkhiqizo "I-Base end surface", bese uzibuyisela ngokuguqulwa kwe-T1-T3 okusekelwe ekuguqulweni kwangempela komkhiqizo (kanye nepulasitiki).

Amathiphu paybe awusizo:

1. Ungakopishi indawo yephrofayela yemikhiqizo yekhasimende ngangokunokwenzeka, zama ukuyidweba ngokwakho. Ukuze, ukuguqulwa kwesikhunta okulandelayo kulula ukushintshwa, kufaka phakathi ukushuba kodonga. uma umumo kuyikhophi evela kumkhiqizo wekhasimende ngemva kokuguqulwa okuningi, idatha ye-3D izothola ukuhlanekezela.
2. Enqubweni yokudweba, ngangokunokwenzeka ukuhlola idatha yomkhiqizo we-2/3D yekhasimende ukuvimbela ukuthi ihlukile.

4, Ukuthambekela kokuguqulwa okungenzeka mayelana nengxenye ebalulekile yomkhiqizo

1, Ukuguqulwa komkhiqizo "Indawo yokuphela kwesisekelo"

Kangangokunokwenzeka ukwenza isenzo sokunciphisa ezintweni zepulasitiki ekuqaleni, kungagwema ukwenza kabusha izingxenye zesikhunta ngangokunokwenzeka. Umugqa obomvu ngezansi ubonisa ithrendi yokuguga elinganiselwe yomkhiqizo. sicela uqaphele ukuthi izimbambo “Zomphathi” noma “ezimise oku-U” noma izinto ezihlobene nazo kufanele zihanjiswe “ngendawo yokuphela kwesisekelo” ndawonye (Okunye okungaphansi komphathi kwehlela phansi ngo-0.5mm, bese “Umphathi” naye ehle ngo-0.5 ), bese udweba abanye. Kunconywa ukusebenzisa "ubuso" (umyalo we-UG) ukuze uwadwebe.

2, Ukuguqulwa komkhiqizo we "Tube orifice"

Umumo werediyasi ethi “R” empandeni yeshubhu kufanele ifane ncamashi nedatha yomkhiqizo wekhasimende, njengoba le radiyasi ethi “R” ithinta amandla endawo ebalulekile yomkhiqizo. Ezimweni ezijwayelekile, ishubhu eliyindilinga kufanele lincishiswe ipulasitiki eceleni kuqala, bese ishintsha inani ngokuya ngokuguquguquka kwangempela, kumashubhu amakhulu, umumo weshubhu mhlawumbe uklanywe njengomumo oval kusengaphambili.

3, umkhiqizo “U” umumo we-plastic bit deformation

Ipulasitiki "ye-U-shape" nayo idinga ukwenza cishe ama-degree angu-2-3, indawo emaphakathi yezimbambo "ze-U -shape" kufanele yenze izinto ezisikiwe eceleni futhi (isithombe 1). Ngemuva kokuthi yonke imikhiqizo idwetshwe kahle bese uklama irediyasi "R" (futhi ukuze kube lula ukushintsha, kwesinye isikhathi ukwakhiwa kabusha kwerediyasi ethi "R" kuzohluleka noma kusetshenziswe isikhathi eside), uma amanye amajiyomethri kudatha yekhasimende ye-3D engazange aphazamiseke, singakwazi. chamfer uma zingaphazamisi ukuhlanganiswa kwezingxenye (amakhasimende amaningi akhetha ukuthi umumo ocijile ufakwe irediyasi ethi “R”). Ngaphezu kwalokho, ezinye i-geometry evelele emzimbeni oyinhloko womkhiqizo zinkulu, lolu hlobo lokuguqulwa komkhiqizo kufanele lunake kakhulu ukuhambisana kanye ne-perpendicularity (isithombe 2).

5, Isiphetho

Ngenhla kukhona okwethu okuhlangenwe nakho ekuklameni umoya ozenzakalelayo kanye nethangi lamanzi- "ukuguqulwa kalula" kwesikhunta somkhiqizo. Ukuqeda lesi sinyathelo kuhle, ngicabanga ukuthi impumelelo eyingxenye yokwakhiwa kwesikhunta esinjalo izotholakala, khona-ke iphi enye ingxenye? sicela ubheke ingxenye elandelayo yalesi sihloko "Ingabe uyazi ukuthi ungayenza kanjani isikhunta sangaphambi kokuguqulwa? -isigaba sokukhiqiza" ngesonto elizayo.
Kulungile, bafundi abathandekayo. ngiyabonga kakhulu ngesikhathi sakho sokufunda lapha.ngibheke phambili ukukubona esigabeni esilandelayo!
