Tikamakamba zakufa, pali njira ziwiri zotsatiridwa - HPDC (High-Pressure Die Casting) kapena Gravity die casting (Low-Pressure Die Casting). Onsewa amagwira ntchito zosiyanasiyana koma amagwiritsa ntchito njira yofanana kuti akwaniritse zomaliza.

Gravity die casting ndi imodzi mwazinthu zakale kwambiri zoponya kufa zomwe zidapangidwa ndi anthu. M'kupita kwa nthawi, adalandira kusintha kwakukulu pazida ndi ntchito yonse yabwino.

M'nkhaniyi, tikambirana za mphamvu yokoka, ubwino wake, ndi ndondomeko yake.

Tanthauzo la mphamvu yokoka kufa kuponyera

Gravity die casting ndi mtundu wa njira yoponyera kufa yomwe imathandizira kupanga mndandanda waukulu. Imagwiritsidwa ntchito m'mafakitale angapo chifukwa chotsika mtengo komanso kutulutsa kwapamwamba komwe imapindula popanda kusokonezedwa ndi anthu. Njirayi imagwiritsidwa ntchito pazinthu zopanda chitsulo, monga aluminiyamu, mkuwa, ndi zinc.

Njira yamakono yokokera kufa imatha kupangidwa mokhazikika kwambiri. Ndiwoyenera kwambiri pazigawo zazikulu, zokhuthala zomwe zimafuna tsatanetsatane wambiri. Zogulitsa kuchokera ku njirayi zimapereka mapeto apamwamba komanso makina apamwamba poyerekeza ndi kuponya mchenga. Ilinso ndi kuponyedwa kwakukulu poyerekeza ndi kuponyedwa kwa mchenga wa aluminiyamu.

Kodi zimasiyana bwanji ndi kuponyera kwamphamvu kwambiri?

High-pressure die casting imagwiritsa ntchito kuthamanga pambuyo pobaya madziwo mukufa. Zimafunikira makina ovuta ndipo zimatsata njira yodzipangira yokha kuti ikwaniritse zotsatira zake. Gravity die casting si njira yodzichitira yokha, yomwe imatsogolera ku kusinthasintha kochepa. Gravity die casting ndiyenso yotsika mtengo paziwirizi.

Kugwiritsa ntchito mphamvu yokoka kufa kuponyera

Gravity die casting ikugwiritsidwa ntchito m'mafakitale ambiri, monga zida zakukhitchini, magalimoto, zida zowunikira, ndi zina, zomwe zimagwiritsidwa ntchito zingapo. Ndizoyenera kupanga zigawo, monga ma knuckles, mitu ya silinda ya injini, midadada ya injini, pistoni, ndi zina zotero. Njira yopangira zinthu imakhala yosasunthika komanso yoyenerera kupanga zinthu zambiri.

Gravity die casting process

Gravity die casting ndi yotchuka kwambiri chifukwa cha njira yake yopanda zinthu zambiri komanso yowongoka. Zimafunikira makina ocheperako, ndipo mutha kusintha zomwe zatulutsidwa mpaka pamlingo wina. Ngati mukuyang'ana ma voliyumu apamwamba, mutha kusintha gawo lalikulu la ntchitoyi.

Nazi zinthu zomwe zikuphatikizidwa mu njira yachikhalidwe yokoka kufa -

1. Kukonzekera imfa

Njirayi imayamba ndikuwotcha ufa pogwiritsa ntchito zoyatsira gasi ndikupopera ndi zokutira zokana. Itha kugwiritsidwa ntchito kangapo ndipo imathandizira kuchotsa kuponya. Imayang'aniranso milingo ya kutentha. Kenako ziwalozo zimasonkhanitsidwa ndikumangidwa.

2. Jekeseni wamadzimadzi

Wogwira ntchitoyo amathira chitsulo chosungunukacho mukufayo. Chitsulo chamadzimadzi chimasiyidwa kuti chikhazikike ndi kuganiza mawonekedwe a kuponyedwa kwa maola angapo. Poponyera mphamvu yokoka, wogwiritsa ntchito makina amagwiritsa ntchito kutsanulira pansi, ndipo amadzaza madziwo pogwiritsa ntchito sprue pansi.

3. Kutulutsa

Chitsulocho chikakhazikitsidwa, kufa kumatsegulidwa, ndipo amachotsa zoponyera. Gawo lotsatira likukhudza kuchotsedwa kwa zida zotayira ndi zikhomo zotulutsa pamanja. Zotsalira, kuphatikizapo zipata, sprues, othamanga, ndi flash, amachotsedwa pazitsulo.

4. Kugwedeza ndi kupukuta

Pambuyo pake, madontho amachotsedwa ndikutsukidwa ndi madzi otentha (pomwe kuli kofunikira). Kukonzekera kumathandizira kuchotsa mbali zonse zakuthwa ndi zinthu zabwino kwambiri. Njira yomaliza imaphatikizapo kuyeretsa kuphulika kuti apereke polishi yofunikira kuzinthu zomaliza.

Ubwino wake

Nazi zifukwa zomwe kuponyera kufa kwamphamvu yokoka kukukulirakulira -

• Ndi imodzi mwa njira zotsika mtengo kwambiri zopangira kufa
• Ndiwothandiza pa ma castings osavuta, makamaka ang'onoang'ono, okhala ndi makulidwe a khoma lofanana komanso opanda zovuta
• Kulondola kowoneka bwino ndi nthawi yopanga mwachangu
• Ndizoyenera kwambiri pamawu okwera kwambiri
• Chophimbacho chikhoza kugwiritsidwa ntchito kangapo ndipo chimafuna ndalama zochepa pokhapokha ndalama zoyamba zakhala zikugwiritsidwa ntchito
• Itha kupanga zida zokhala ndi makina apamwamba kwambiri (monga kutsika kwa gasi ndi njere zabwino) zoyenera kwambiri pochiza kutentha.
• Chogulitsa chomaliza chimafuna kumalizidwa pang'ono komanso kumangidwa chifukwa cha zabwino zake

Womba mkota

Pali zinthu zingapo zomwe ziyenera kuganiziridwa musanasankheprecision kufa kuponyerandondomeko yomwe mwasankha. Zimaphatikizapo zofunikira zamtundu monga zovuta, kukhulupirika, kutha kwa pamwamba, ndi makina. Tiyeneranso kuganizira nthawi yotsogolera, kuchuluka kwa kupanga, ndi zina zamalonda. Zitsulo zokhala ndi malo osungunuka kwambiri sizomwe zili zabwino kwambiri pakuponya mphamvu yokoka.
