KUPANGA DIE
Taiyuan Simis Investment Casting Co., Ltd.Taiyuan Simis Investment Casting Co ndi kampani yotsogola kwambiri yopangira zinthu zotayidwa ku China, yomwe imayang'ana kwambiri kupatsa makasitomala njira zophatikizira zinthu zotayidwa ndi aluminiyamu komanso zinc kuyambira pakupanga nkhungu mpaka kupanga zinthu zambiri. Ndi satifiketi ya ISO 9001 ndi CE, timatumikira makasitomala opitilira 300 padziko lonse lapansi.
Die Casting, njira yapamwamba yopangira zitsulo, imayendetsa chitsulo chosungunuka kukhala zinyalala zolondola ndi mphamvu komanso liwiro lapadera. Yodziwika ndi kupanikizika kwake kwakukulu kwa 200-400MPa komanso kuthamanga kwa jakisoni kwa 16-80 m/s, njira iyi imakwaniritsa kudzaza kwathunthu kwa nkhungu ndi kulimba mkati mwa zenera lodabwitsa la masekondi 0.01-0.2. Makamaka yosinthira ma aluminiyamu, zinc, ndi magnesium alloys omwe amapanga zinthu zambiri, die casting imapereka kulondola kodabwitsa kwa ±0.02mm ndi kukonzedwa bwino kwa pamwamba pa Ra0.8-6.3μm, pomwe ikuchepetsa zofunikira pambuyo pokonza ndi 60% poyerekeza ndi njira zachikhalidwe zoponyera.

Kuponya chitsulo chotentha (chomwe chimatchedwa gooseneck casting) chimapangidwa makamaka popanga zinthu zazing'ono mpaka zapakati pogwiritsa ntchito makina ophatikizira ng'anjo. Njirayi ili ndi njira yojambulira yomwe imayikidwa pansi pomwe chitsulo chosungunuka chimasungidwabe kutentha mkati mwa chipinda cha ng'anjo. Chopopera cha hydraulic chimayendetsa chitsulo chosungunuka kudzera mu ngalande ya gooseneck kupita ku zinyalala zolondola.
Njirayi imapereka nthawi yofulumira yozungulira chifukwa cha kupezeka kwa chitsulo nthawi zonse m'chosungiramo chotenthetsera. Kugwiritsa ntchito kwake kumangogwiritsidwa ntchito pazitsulo zomwe kutentha kwake kumachepa, kuphatikizapo zinc alloys, magnesium composites, ndi zinthu zina zopangidwa ndi mkuwa, zomwe zimapangitsa kuti kuyenda bwino kuyende bwino panthawi yopangira.

Kuponya miyala ya chipinda chozizira, komwe kali ndi kapangidwe kake kosiyana ka jekeseni, kumapereka ubwino waukulu popanga zida zazikulu zogwirira ntchito ndi zitsulo zolimba kwambiri. Njirayi imayambitsa madzi achitsulo osungunuka molondola m'chipinda cholowetsamo jekeseni kutentha kwa chipinda (15-25℃) pothira ndi manja, kenako yankho lachitsulo limakanikizidwa mu dzenje la nkhungu mwachangu kwambiri pogwiritsa ntchito makina opopera amphamvu kwambiri. Dongosolo lolowetsa lopangidwa ndi chitsulo chapadera limapewa kuuma msanga kwa yankho lachitsulo.
Ndi mitundu yosiyanasiyana ya zinthu zomwe zingagwiritsidwe ntchito, ukadaulowu umagwirizana ndi zinthu monga aluminiyamu, mkuwa ndi chitsulo choponyedwa, kuonetsetsa kuti ziwalo za kapangidwe kake zimakhala bwino komanso zimathandizira kwambiri kukhazikika kwa njira poteteza chitsulo chamadzimadzi ku kutentha kosalekeza. Komabe, ziyenera kudziwika kuti nthawi yopangira yake ndi yayitali ndi 30-40% kuposa njira yopangira chipinda chotentha, kusinthasintha kwa njira yopangira chifukwa cha kulumikizana ndi dzanja komanso kugwiritsa ntchito mphamvu zambiri chifukwa cha njira yopangira nthawi ndi nthawi ndiye zoletsa zazikulu za ukadaulo uwu pakugwiritsa ntchito.

Makina oponyera zitsulo ozungulira amatha kukonza zitsulo zosiyanasiyana (monga zinc, aluminiyamu, mkuwa, ndi zina zotero), zomwe nthawi zambiri zimagwiritsidwa ntchito popanga mawonekedwe apadera kapena zigawo zolondola kwambiri. Dongosolo lake lojambulira lolunjika molunjika limatsimikizira kukhazikika kwabwino kwa kudzaza ndi kuchepa kwa ma porosity, zomwe zimapangitsa kuti likhale labwino kwambiri pazinthu zomwe zimafuna ma geometri ovuta kapena zomangamanga zopyapyala.
Kapangidwe ka nkhungu kothandizidwa ndi mphamvu yokoka kamawonjezera mphamvu yopangira zinthu pamene kamachepetsa zinyalala za zinthu, makamaka zoyenera kupanga zida zamagalimoto, zolumikizira zamagetsi, ndi zida zamafakitale motsatira malamulo okhwima. Kuwongolera kutentha kwapamwamba komanso njira zotulutsira zinthu zokha zimathandizira kuti nthawi yozungulira ikhale yogwira ntchito, kuonetsetsa kuti zinthu zambiri zibwerezabwereza.
Kuponya die casting yopanikizika kwambiri ndi njira yomwe madzi achitsulo amayikidwa pamphamvu kwambiri (mpaka 150MPa) ndi makina oponyera die casting, kotero kuti madzi achitsulo amadzaza dzenje la nkhungu mwachangu kwambiri ndikulimba akapanikizika.
Chimake cha ndondomekoyi ndi "kupanikizika kwakukulu ndi liwiro lalikulu", yoyenera kupanga khoma lopyapyala, zigawo zovuta (monga chipolopolo cha injini ya galimoto, zida zamagetsi).
Zipangizo zogwiritsidwa ntchito: amagwiritsidwa ntchito makamaka pa zitsulo zopanda chitsulo (monga aluminiyamu, zinki, magnesium alloy), makamaka zoyenera pa zitsulo zotsika kwambiri.
Ubwino ndi Kuipa
* Ubwino: kupanga bwino kwambiri, kumaliza bwino pamwamba, kulondola kwakukulu.
* Zoyipa: mtengo wokwera wa nkhungu, zosavuta kupanga ma porosity ndi zolakwika za shrinkage, kuponyera sikungakhale chithandizo cha kutentha.

Kuponya mpweya wochepa kumagwiritsa ntchito mpweya wopanikizika (nthawi zambiri kupanikizika kumakhala 20 ~ 100kPa) kuti akanikizire madzi achitsulo kuchokera pansi kupita pamwamba kulowa mu chikombole, ndikulimba pansi pa kupanikizika. Liwiro lodzaza ndi lochepa, koma madzi achitsulowo amayenda bwino, oyenera zigawo zazikulu zopyapyala za khoma (monga hub, silinda head).
Zipangizo zogwiritsidwa ntchito: Aluminiyamu ndiye chinthu chachikulu, komanso chingagwiritsidwe ntchito popanga magnesium alloy, mkuwa alloy ndi zitsulo zina zopanda chitsulo.
Ubwino ndi Zoyipa
Ubwino: kukhuthala kwakukulu kwa kuponyera, ma pores ochepa, amatha kutenthedwa, kugwiritsa ntchito zinthu zambiri (chokwera chaching'ono).
Zoyipa: ndalama zambiri zogulira zida, ntchito yabwino yopangira zinthu ndi yotsika poyerekeza ndi kuponyera kwamphamvu.

Madzi achitsulo amadalira mphamvu yokoka kuti adzaze mwachilengedwe m'chimake chachitsulo, popanda kukakamizidwa ndi kunja, njirayi ndi yosavuta ndipo nthawi ya nkhungu ndi yayitali.
Pali mitundu iwiri:
Kuponya kwa mphamvu yokoka ya mchenga: Pogwiritsa ntchito nkhungu ya mchenga, yoyenera kupanga chidutswa chimodzi kapena gulu laling'ono, pamwamba pa chopangiracho ndi poyipa.
Kuponyera kwachitsulo: Pogwiritsa ntchito nkhungu yachitsulo chosagwira kutentha, zinthu zoponyedwazo ndi zolimba komanso zokhazikika, zoyenera zigawo za khoma lapakati ndi lalikulu (monga maziko a makina)

Zinc die casting imagwiritsa ntchito kwambiri njira yopangira chipinda chotentha, kumiza njira yopangira jekeseni mwachindunji mkati mwa zinc yosungunuka. Zinc alloys zomwe zimagwiritsidwa ntchito kwambiri monga mndandanda wa Zamak—kuphatikizapo Zamak 3 ndi Zamak 5—zimasakaniza zinc ndi aluminiyamu, magnesium, ndi mkuwa. Zinc alloys izi zimakhala ndi kusinthasintha kwapadera, zomwe zimathandiza kupanga mapangidwe ovuta komanso makoma owonda kwambiri (oonda ngati ~0.5 mm). Zamak 5, yodziwika ndi kuchuluka kwa aluminiyamu, imapereka mphamvu zapamwamba kwambiri zamakaniko pomwe imasunga luso lopanga molondola.
Ubwino: Kukonza bwino kwambiri komanso kusalala kwa pamwamba kumachepetsa makina ena ogwirira ntchito; kumachepetsa mtengo chifukwa chogwiritsa ntchito mphamvu zochepa komanso kupanga mwachangu; kulimba komanso kukhala ndi mphamvu zamphamvu zamakanika komanso kukhazikika kwa mawonekedwe; zinthu zobwezerezedwanso zimathandiza kuti zinthu zizikhala zokhazikika; kusinthasintha ndi ma plating, penti, kapena zokutira zosagwirizana ndi dzimbiri.
Zoyipa: Zolemera kuposa aluminiyamu/magnesium chifukwa cha kuchuluka kwa zinc; zimatha kuwononga popanda zophimba zoteteza; mtengo wokwera wa zida zoyambira zimapangitsa kuti magulu ang'onoang'ono asamayende bwino.

Kuthira mkuwa pogwiritsa ntchito die casting kumalowetsa zitsulo zosungunuka zamkuwa (monga mkuwa, bronze) mu zitsulo zosungunuka pansi pa kupanikizika kwakukulu. Chifukwa cha kutentha kwa mkuwa (~1085°C), njira yozizira ya chipinda imagwiritsidwa ntchito, komwe chitsulo chimayikidwa mu chipinda china, zomwe zimapangitsa kuti chikhale chocheperako komanso chogwiritsa ntchito mphamvu zambiri kuposa zinc die casting. Mkuwa woyera nthawi zambiri supangidwa chifukwa cha reactivity ndi zovuta, pomwe zitsulo monga mkuwa ndi bronze zimapangitsa kuti ziume bwino, zikhale zolimba, komanso kuti zisawonongeke.
Ubwino wake: umaphatikizapo kutentha/magetsi abwino kwambiri, kukana dzimbiri (makamaka m'malo okhala ndi madzi a m'nyanja), mphamvu zophera tizilombo toyambitsa matenda, komanso kukongola kwake kokhala ndi zomaliza ngati golide.
Zoyipa: mtengo wokwera wa mphamvu, kuwonongeka kwa zida mwachangu chifukwa cha kutentha/kupanikizika, kusinthasintha pang'ono kwa madzi (kofunikira makoma okhuthala), komanso mitengo yokwera ya zinthu poyerekeza ndi zovuta za zinc kapena aluminiyamu. Kuponya zinc die kumapereka ndalama zochepa, kukonza kosavuta, komanso kusinthasintha kwakukulu kwa kapangidwe chifukwa cha kusinthasintha kwamadzi.
