Cast Steel Frame Castings

Timathandizira kupanga zinthu ndi mitundu ikuluikulu itatu, iliyonse yogwirizana ndi zochitika zosiyanasiyana zamagwiritsidwe ntchito komanso momwe amagwiritsidwira ntchito, kuonetsetsa kuti makasitomala athu akwera mtengo wokwanira-kagwiritsidwe ntchito kake:

Chitsulo cha Carbon: Chotsika mtengo-chogwira ntchito bwino, champhamvu kwambiri komanso champhamvu chokwanira, choyenerera-zigawo zodziwika bwino za chimango, zomwe zimagwiritsidwa ntchito kwambiri m'magalimoto amalonda.

Chitsulo cha Alloy: Kulimba kwamphamvu kwambiri, kusagwira ntchito, komanso kusatopa, kothandiza-kuchulukirachulukira, kumagwira ntchito movutikira (monga-magalimoto onyamula katundu, magalimoto oinjiniya), kukulitsa moyo wautumiki.

Ductile Iron (Nodular Cast Iron): Imalinganiza mphamvu ndi kulimba, ndikumayamwa bwino komanso kukana kuvala, yoyenera pazigawo zomwe zimafuna kugwira ntchito mokhazikika pansi pamavuto ovuta.

Makasitomala athu amadzaza-zinthu zambiri zolemetsa, zomwe zimathandiza-kugula zinthu kwamakasitomala kumodzi, kuphatikiza koma osati zokhazo:

Ma thrust Rods: Onetsetsani kuti galimoto ikuyenda mokhazikika, mphamvu zakutsogolo komanso zautali pakuyendetsa.

Leaf Spring Assemblies & Mounts: Nyamulirani kulemera kwagalimoto, kutengera zoopsa za pamsewu, ndikuyendetsa bwino.

Kukonza Mabakiteriya: Kuti muteteze injini, ma transmissions, ma axles, ndi zigawo zina zofunika, ndi malo olondola kwambiri.

Mapaipi a Exhaust & Manifolds: High-kutentha kwapamwamba, kusagwira kwa dzimbiri, kuonetsetsa kuti mpweya umakhala wosalala komanso wochepetsera phokoso.

Ma Brackets a Shock Absorber: Lumikizani zotsekera pachithunzichi, onjezerani kugwedezeka kwapadera, ndikuteteza zida za chassis.

Timavomerezanso kupanga makonda malinga ndi zojambula zamakasitomala, zitsanzo, ndi zofunikira zinazake, zomwe zimakhudza mitundu yonse ya mafelemu-ojambula okhudzana ndi magalimoto olemera.

Kuti tikwaniritse zofunikira zosiyanasiyana zamagawo omwe ali m'malo osiyanasiyana ogwira ntchito, timapereka chithandizo chamankhwala chaukadaulo, kuphatikiza:

Annealing: Chepetsani kupsinjika kwamkati, sinthani kulimba kwa zinthu ndi machinability.

Kuzimitsa & Kutentha: Limbikitsani kulimba kwa zinthu, kulimba, ndi kusagwira ntchito, kutengera-zigawo zolemetsa kwambiri.

Normalizing: yeretsani kamangidwe kambewu, sinthani zinthu zofanana ndi makina.

Njira yathu yochizira kutentha imayendetsedwa mosamalitsa, kutsatira miyezo yapadziko lonse lapansi, kuonetsetsa kuti magwiridwe antchito amtundu uliwonse akuponya.

Kutalikitsa moyo wantchito ya mafelemu oponya m'malo ovuta (monga chinyezi, fumbi, ndi dzimbiri), timapereka chithandizo chothana ndi dzimbiri pamwamba pa -, kuphatikizapo:

Kutentha-Dip Galvanizing: Kusawononga kwabwino kwambiri, koyenera kugwiritsidwa ntchito kwa nthawi yayitali-panja.

Kupaka kwa Electrophoretic: Kupaka yunifolomu, kumamatira mwamphamvu, kumateteza bwino dzimbiri ndi dzimbiri.

Kupopera Paint: Mitundu yosinthika mwamakonda, zokongoletsa zabwino komanso zoteteza, zomwe zimagwirizana ndi zosowa zosiyanasiyana zamakasitomala.

1.1 Dzina lazogulitsa ndi Ntchito

Chogulitsachi ndi cing yophatikizika (yomwe tsopano ikutchedwa "casting"), yomwe ndi gawo lalikulu-lonyamula katundu wamitundu yosiyanasiyana ya zida zamakina (magalimoto, zomangira, zida zapadera, ndi zina zotero). makamaka ntchito kuthandiza powertrain, dongosolo kuyimitsidwa, ndi kapangidwe thupi. Kupyolera mu kapangidwe ka chimango chokhala ndi matabwa aatali ndi amtengo wapatali, amakwaniritsa kusamutsidwa kwa katundu, kukhazikika kwapangidwe, ndi kukana todeformation, kukhala chinthu chofunikira kwambiri kuti zitsimikizire chitetezo chogwira ntchito ndi kudalirika kwa zipangizo.

 

1.2 Kapangidwe kazogulitsa

Imatengera "Lu-yowoneka ngati" yotsekeredwa ndi zomangira zautali ndi zopingasa (kapena molingana ndi mafotokozedwe enieni a kapangidwe kazinthu, monga mawonekedwe ophatikizika-oponyera), kukulitsa mphamvu ndi kulimba kwapang'onopang'ono popewa kupsinjika; Mapangidwe ofanana a khoma, okhala ndi madera ofunikira okhala ndi makulidwe a 3-8mm gradient khoma (mawonekedwe azojambula), pogwiritsa ntchito masinthidwe otsetsereka (otsetsereka Kuchepera kapena kofanana ndi 1:kuchulukira kwa zinthu za uce ndikuchepetsa chiwopsezo cha kuchulukira kwa zibowo ndi porosity; Nthiti zokonzedwa motsatira njira yopingasa kapena kusuntha kofanana ndi kusuntha kwamphamvu, 5mm arctransitions amayikidwa pakati pa nthiti zazitali kuti apititse patsogolo kukana kwa ming'alu ndi kusinthasintha kwapangidwe, kusunga malo osungiramo kuyimitsidwa, kugwedezeka, mipando, etc.
