ASF - Audi Space Frame

ASF imakhala ndimagawo otsekedwa omwe amalumikizidwa kudzera mumisonkhano yopangira jekeseni. Malinga ndi Audi, kusinthidwanso kwake ndi kasanu kuposa kwachitsulo.

Mphamvu zonse zofunika pakupanga ndi 152-163 GJ poyerekeza ndi 127 GJ ya ngolo yofanana yazitsulo.

Kutulutsidwa

Kwenikweni, amapangidwa ndi mbiri yooneka ngati bokosi. Mitundu yama alloys omwe amagwiritsidwa ntchito ndi ma alloys osindikizidwa a Al-Si okhala ndi Si wamkulu kuposa 0,2% kuwonetsetsa kutuluka kwanyengo komanso kutsika kwa mvula mukakalamba.

mapepala

Amagwiritsa ntchito mapanelo onyamula katundu, slabs, madenga ndi zotetezera moto, amawerengera 45% ya kulemera kwake. Makulidwe awo ndi 1.7-1.8 kukula kuposa chitsulo. Alloy 5182 yomwe imagwiritsidwa ntchito mu boma la T4 (yowonongeka kwambiri) yokhala ndi malire a 140-395 MPa. Itha kulimbikitsidwa ngakhale ili ndi magnesium yochepera 7% chifukwa chakupezeka kwa ma alligants ena.

Mayunitsi Osewera

Amagwiritsidwa ntchito m'malo opanikizika kwambiri.

Zimachitika pogwiritsa ntchito njira yotchedwa VACURAL, yomwe imakhudza kuyika zotayidwa zamadzimadzi muzitsulo zopangira kuti mupeze:

Makhalidwe apamwamba komanso ofanana, otsika kwambiri, kuti athe kutsimikizira kuti ali ndi makina osakanikirana ndi kulimba komwe kumafunikira kukana kutopa;

Weldability wabwino wofunikila kujowina ndi mbiri.

Njira zolumikizira

Njira zingapo zimagwiritsidwa ntchito:

Kuwotcherera kwa MIG: amagwiritsidwa ntchito pamapepala ochepera komanso polumikizira mfundo ku mbiri;

Kuwotcherera kwa malo: kwa chitsulo chosafikika ndimapula msomali;

Kukhazikika: kofunika kwambiri kuchokera pakapangidwe kake chifukwa chakuchepa kwamphamvu; amagwiritsidwa ntchito polumikizira mapepala kuti alimbitse malo owonjezera;

Kubowoleza: imagwiritsidwa ntchito ponyamula zinthu zokhala ndi malo owonjezera; ndi makulidwe omwewo, imakhala yolimbana ndi 30% poyerekeza ndi kuwotcherera; lilinso ndi mwayi wofuna mphamvu zochepa ndipo silisintha kapangidwe kazinthuzo.

Zomatira zomangamanga: amagwiritsira ntchito galasi lokhazikika, pakhomo ndi ma bonnet olumikizirana (pamodzi ndi zomangira), mukugwedezeka kwamphamvu (pamodzi ndi riveting ndi kuwotcherera).

Msonkhano

Pambuyo akamaumba, msonkhano umachitika ndi kuwotcherera maloboti a zigawo zikuluzikulu.

Kumaliza kumachitika ndi kupukusa ndi kusungunula ndi ma cations atatu (Zn, Ni, Mn), omwe amalimbikitsa kulumikizana kwa katapositi wa cataphoresis pomiza.

Kujambula kumachitika mofanana ndi matupi azitsulo. Pakadali pano, ukalamba woyamba kupanga umachitika, womwe umamalizidwa ndikuwonjezera kutentha kwa 210 ° C kwa mphindi 30.
