Mchenga woponyera umagwiritsidwa ntchito kupanga zigawo zingapo zachitsulo zomwe zimakhala ndi ma geometies. Magawo awa amatha kukhala osiyanasiyana kukula komanso kulemera kwake, kuyambira angapo matani angapo. Magawo ena opondapondapondapo pang'ono amaphatikiza zigawo zina monga magiya, ma pulleys, ma crankshafts, zolumikizira, ndi osewera. Ntchito zazikuluzikulu zimaphatikizapo mdeti wa zida zazikulu ndi zigawo zolemera zamakina. Kuponyera mchenga kumakhalansonso kofala pakupanga magalimoto, monga injini zamalodi, injini kutanthauzira, mitu ya silinda, ndi milandu yotumiza.
Mchenga woponyera, womwe umagwiritsidwa ntchito kwambiri, umagwiritsa ntchito nkhungu zogwiritsidwa ntchito ngati zomwe zimagwiritsidwa ntchito kuti zipangidwe zitsulo zomwe zitha kupangidwa pafupifupi chimodzi. Chifukwa nkhundambe za mchenga ziyenera kuwonongedwa kuti zichotse gawo, lotchedwa kuponyera, mchenga womwe ukutuluka womwe umakhala ndi zochepa. Njira yobwereka mchenga imaphatikizapo kugwiritsa ntchito ng'anjo, chitsulo, mawonekedwe, ndi mchenga. Zitsulo zimasungunuka mu ng'anjo kenako nkuwerama ndikuthira m'mbale ya mchenga, womwe umapangidwa ndi mawonekedwe. Mchenga nkhunda umasiyanitsa mzere wopindika ndipo kuponyera kokhazikika kumatha kuchotsedwa. Njira zomwe zimafotokozedwazo zikufotokozedwa mwatsatanetsatane mu gawo lotsatira. Mchenga woponya, zida zoyambirira ndi nkhungu, zomwe zimakhala ndi zinthu zingapo. Mvula imagawidwa m'magawo awiri - COP (Hard Har) ndi kokoka (pansi (theka), yomwe imakumana pamzere wopindika. Ma halves onse awiriwa amapezeka mkati mwa bokosi, lotchedwa Flask, yomwe imagawidwa pamzerewu. Patseke la nkhungu limapangidwa ndi mchenga kuzungulira mawonekedwe mu theka la flaski. Mchenga ukhoza kunyamula ndi dzanja, koma makina omwe amagwiritsa ntchito kupanikizika kapena kukhudzidwa kutsimikizika ngakhale kulongedza kwa mchenga ndipo kumafuna nthawi yochepa, ndikuti kuwononga ndalama. Mchenga utadzaza ndi ndondomekoyi imachotsedwa, khola limakhalapo lomwe limapanga mawonekedwe akunja akuponyedwa. Malo ena amkati akuponyedwa akhoza kupangidwa ndi ma cores.
Mchenga woponyera umatha kugwiritsa ntchito pafupifupi gawo lililonse. Ubwino wa mchenga ndikutha kutaya zinthu zotulutsa zokhala ndi kutentha kwambiri, kuphatikizapo chitsulo, nickel, ndi titanium. Zipangizo zinayi zambiri zomwe zimagwiritsidwa ntchito mu mchenga zikuwonetsedwa pansipa, limodzi ndi kutentha kwawo
Zida kutentha kutentha
Aluminiyamu aludos 1220 ° F (660 ° C)

Mtengo wa mchenga umaphatikizapo mtengo wa chitsulocho, kusungunuka chitsulo, mchenga wombewu, komanso mchenga wokhazikika. Mtengo wachitsulo umatsimikizika ndi kulemera kwa gawo, kuwerengeredwa kuchokera mbali ndi kachulukidwe kazinthu, komanso mtengo wa zinthuzo. Mtengo wosungunuka udzakhalanso wokulirapo gawo lalikulupo ndipo limayendetsedwa ndi zinthuzo, monga momwe zinthu zina zimakhala zokwera mtengo kuti zisungunuke. Komabe, mtengo wosungunuka umakhala wosafunikira poyerekeza ndi zinyalala. Kuchuluka kwa mchenga wowuma womwe umagwiritsidwa ntchito, ndipo chifukwa chake mtengo wake, umakhalanso wofanana ndi kulemera kwa gawo. Pomaliza, mtengo wa mchenga wapakati umatsimikiziridwa kuchuluka ndi kukula kwa ma cores omwe amagwiritsidwa ntchito pochita.
Ubwino Wotulutsa Mchenga
Imatha kupanga ziwalo zazikulu kwambiri
Imatha kupanga mawonekedwe ovuta
Zosankha zambiri zakuthupi
Zowonjezera zotsika ndi zida
Scrap ikhoza kubwezeretsedwanso
Nthawi Yofupikira
Mapulogalamu:
Makina omangamanga, magawo osindikizira, injini zamagetsi, zigawo zamakina, ma grars, magawo azamadzi, zida zamagalimoto, ectiles.
