Kwi-ballet entsonkothileyo yokwenziwa kweemoto, apho ukhuseleko luhlangabezana nesimbo kunye nokusebenza, zimbalwa izinto ezithwala uxanduva olubalulekileyo njenge-A-pillar. Le ntsika yolwakhiwo, efake i-windshield kunye neengcango zangaphambili, ibalulekile ekuqiniseni uphahla, ukhuseleko lokuwa, kunye nokuqina kwesithuthi ngokubanzi. Kodwa ngaphambi kokuba ibe yinxalenye entle neqinileyo yomzimba wemoto yakho emhlophe, iqala uhambo lwayo olubunjwe yingcali yokulawula isinyithi:I-Die yokunyathela yeMoto.

Ezi dayi zingaphezulu kakhulu kunezibumba ezilula. Zizixhobo ezinobuchule obuphezulu, ezichanekileyo ezenzelwe ukuguqula amaphepha asicaba esinyithi esiphambili esinamandla aphezulu (AHSS) okanye i-aluminium abe yi-geometry entsonkothileyo, enemilinganiselo emithathu ye-A-pillar. Le nkqubo idla ngokubandakanya iidayi eziqhubekayo zokunyathela, apho umcu wesinyithi uhamba kwizitishi ezininzi ngaphakathi komatshini omnye wokucinezela, uqhubeka nemisebenzi elandelayo:

Ukuqhawula: Ukusika umphezulu wokuqala wenxalenye kwikhoyili.

Ukugqobhoza: Ukudala imingxunya yokufakelwa kweengcingo, yokukhupha amanzi, okanye yokuhlanganisa kwixesha elizayo.

Ukwenziwa/Umzobo: Elona nqanaba libalulekileyo. Apha, umngxuma wedayi kunye nokubhoboza kuyasolula kwaye kugobe isinyithi kwiindlela ezinzulu, ezihlala zinciphile, zepilara ngaphandle kokukrazuka okanye ukushwabana.

Ukusika: Ukususa izinto ezingafunekiyo ukuze kufunyanwe imo yokugqibela yenethi.

Ukujija: Ukwenza imiphetho yokujija okanye yokutywina imiphezulu.

Kutheni i-A-Pillar Dies ifuna ubunjineli obuphezulu:

Ukuyila nokwakha idayisi yokunyathela eneentsika ezi-A kuzisa imingeni eyahlukileyo:

Ijiyometri Entsonkothileyo: Ii-A-pillars zihlala zine-tight radii, utshintsho olukhulu lobunzulu, ii-compound curves, kunye nee-precise flanges - zonke ezi zinto zifuna indawo entsonkothileyo yokudaya.

Imingeni yezinto eziphathekayo: I-AHSS yanamhlanje inika umlinganiselo omangalisayo wamandla nobunzima kodwa iyaziwa ngokuba nzima ukuyila. Iidayi kufuneka zisebenzise amandla amakhulu, alawulwayo ngelixa zinciphisa uxinzelelo olunokubangela ukuqhekeka.

Ukuchaneka Okubalulekileyo: Nokuba ukuphambuka okuncinci kunokuchaphazela ukufakwa kwefestile, ukulungelelaniswa kocango, kwaye ekugqibeleni, ukusebenza kokuwa. Iidayi kufuneka zenziwe ngomatshini ukuze zilungelelaniswe nezinga le-micron.

Ulawulo lweSpringback: Izinto ezinamandla aphezulu "zibuyela umva" emva kokuba zenziwe. Imiphezulu ye-die kufuneka ihlawulwe ngokuchanekileyo (igobe kakhulu) ukuqinisekisa ukuba inxalenye yokugqibela iphumla kwimo efunekayo.

Ukugqitywa Komphezulu Nokuqina: Idayi kufuneka ivelise ukugqitywa komphezulu okufana neClass-A okanye okufana neClass-A kwicala langaphandle lolusu. Kwangaxeshanye, idayisi ngokwayo kufuneka imelane nezigidi zemijikelo phantsi koxinzelelo olukhulu, ifuna izixhobo eziqinileyo kunye nonyango oluntsonkothileyo lomphezulu.

Ngaphaya kokuBumba: Indima kuKhuseleko nakuMgangatho

Ukuchaneka okufezekiswe yi-stamping die kuchaphazela ngokuthe ngqo:

Ukunyaniseka kwesakhiwo: Ukwakheka ngokuchanekileyo kuqinisekisa ukusasazwa kwezinto kunye nobukhulu obufanayo, okubalulekileyo ekufunxeni amandla okuqhekeka ngokufanelekileyo.

Ukulingana Nokugqitywa: Ubungakanani obuchanekileyo buqinisekisa ukuhlanganiswa okungenamthungo nefestile yemoto, uphahla, iingcango, kunye nedeshibhodi, okuthintela ingxolo yomoya, ukuvuza kwamanzi, kunye neziphene zobuhle.

Ukuphucula Ubunzima: Ukwenziwa kakuhle kunciphisa inkunkuma yezinto kwaye kuvumela ukusetyenziswa kwentsimbi ebhityileyo neqinileyo, nto leyo enegalelo ekunciphiseni ubunzima besithuthi ngokubanzi.

Umda Ophambili: Ukulinganisa kunye noBuchule

Uphuhliso lwe-die lwanamhlanje luxhomekeke kakhulu kwisoftware ye-Finite Element Analysis (FEA). Iinjineli zilinganisa yonke inkqubo yokwenza ngekhompyutha, ziqikelela iingxaki ezinokubakho ezifana nokuqhekeka, imibimbi, okanye ukuncitshiswa okugqithisileyo ngaphambi kokuba intsimbi isikwe. Oku kuvumela ukulungiswa kwe-die geometry, ukuqikelela/ukuhlawula i-springback, kunye nohlalutyo lokuhamba kwezinto, okunciphisa kakhulu ukuzama okubizayo kunye namaxesha okukhokela.

Ngaphezu koko, izinto ezintsha ezifana nee-presses eziqhutywa yi-servo zibonelela ngolawulo olungenakuthelekiswa nanto kwiiprofayili zentshukumo yesilayidi kunye ne-force motion, nto leyo evumela ukuba iijometri ze-A-pillar ezintsonkothileyo kunye nokwenziwa ngcono kwezinto ezinzima.

Isiphelo

I-Automotive A-Pillar Metal Stamping Die ngummangaliso wobunjineli obuchanekileyo, obusebenza ngasemva kweziganeko ukudala icandelo elisisiseko kukhuseleko lwezithuthi, ubuhle, kunye nokusebenza. Uyilo lwayo oluntsonkothileyo, ukunyamezelana kwemveliso okufunekayo, kunye nokukwazi ukuphatha izixhobo eziphambili kuyenza ibe yinto ebalulekileyo, enexabiso eliphezulu kwikhonkco lokubonelela ngezithuthi. Ukutyala imali kuyilo lwedayi oluphambili, ukulinganisa, kunye nolwakhiwo oluqinileyo akupheleli nje ekubumbeni isinyithi; kumalunga nokwakha ukhuseleko kunye nomgangatho wezithuthi esiziqhubayo. Ngexesha elizayo xa ungena emotweni, jonga i-A-pillar - amandla ayo kunye nokulingana kwayo ngokugqibeleleyo bubungqina beqhawe elingadunyiswanga kwi-stamping press.
