Kupanga ndi chiyani
Forging ndi njira yopangira zinthu potenthetsa zitsulo ku pulasitiki ndikugwiritsa ntchito mphamvu kuti apange zinthuzo. Izi zimalola kuti zinthuzo zisundidwe, wopanikizidwa, kapena kutambasulidwa mu mawonekedwe omwe mukufuna. Kupanga kumatha kuthetsa zolakwika monga kuponyera porosity yomwe imapangidwa panthawi yazitsulo, onjezerani microstructure, ndi chifukwa chakuti zitsulo zonse zachitsulo zimasungidwa, makina a forgings nthawi zambiri amakhala apamwamba kuposa ma castings azinthu zomwezo.
Chiyambi cha kutentha recrystallization zitsulo ndi za 727 ℃, koma 800 ℃ amagwiritsidwa ntchito ngati mzere wogawa. Pamwamba pa 800 ℃ ndi kupanga kotentha; pakati pa 300-800 ℃ imatchedwa kufota kotentha kapena kufota kotentha, ndipo kupeta ndi kutentha kwa chipinda kumatchedwa kuzizira kozizira.
Kupanga magawo okhudzana ndi kukweza nthawi zambiri kumagwiritsa ntchito zida zotentha.
Kupanga ndondomeko
Njira zopangira ma bolts otentha ndi: kudula → kutentha (kukaniza waya kutentha) → kuumba → kukhomerera → kudula → kuphulitsa → kuphulitsa → kupukuta → kusonkhezera → kuyeretsa waya
Kudula: Dulani kapamwamba kozungulira mu utali woyenerera
Kutentha: Tenthetsani kapamwamba kozungulira kukhala pulasitiki ndi kutentha kwa waya
Kupanga: Sinthani mawonekedwe azinthu ndi mphamvu mothandizidwa ndi nkhungu
Kukhomerera: Pangani dzenje pakati pa workpiece
Kuchepetsa: Chotsani zinthu zowonjezera
Kuwombera mfuti: Chotsani ma burrs, kuwonjezera pamwamba kumaliza, kuwonjezera roughness, ndi kuthandizira galvanizing
Ulusi: Pangani ulusi
Kukongoletsa: Wonjezerani kukana dzimbiri
Kuyeretsa waya: Pambuyo galvanizing, pakhoza kukhala zinc slag yotsalira mu ulusi. Njirayi imatsuka ulusi ndikuonetsetsa kuti imakhala yolimba.
Mawonekedwe a zida zopukutira
Poyerekeza ndi ma castings, zitsulo kukonzedwa ndi kupanga akhoza kusintha microstructure ndi mawotchi katundu. Pambuyo pomanga njira otentha ntchito mapindikidwe a kuponya dongosolo, chifukwa mapindikidwe ndi recrystallization wa zitsulo, mbewu zoyambirira za coarse dendrite ndi columnar zimakhala njere zomwe zimakhala zabwino kwambiri komanso zogawidwa mofanana ndi mawonekedwe opangidwanso.. Tsankho lapachiyambi, kutayirira, pores, ndi inclusions mu ingot zitsulo ndi opangidwa ndi welded ndi kuthamanga, ndipo mapangidwe awo amakhala ophatikizika, zomwe zimawonjezera pulasitiki yachitsulo ndi zinthu zamakina.
The makina zimatha castings ndi otsika kuposa forgings wa zinthu zomwezo. Kuphatikiza apo, kukonza kukonza kungatsimikizire kupitiliza kwa kapangidwe kachitsulo kachitsulo, kotero kuti mawonekedwe a ulusi wa forging amagwirizana ndi mawonekedwe opangira, ndipo mzere wachitsulo wachitsulo suli bwino, zomwe zingatsimikizire kuti mbalizo zimakhala ndi makina abwino komanso moyo wautali wautumiki. Zopangira zopangidwa mwaluso kwambiri, ozizira extrusion, ndi njira zotentha za extrusion sizingafanane ndi castings.
Forgings ndi zinthu zomwe zimawumbidwa ndi kukakamiza kuchitsulo kudzera pakusintha kwapulasitiki kuti zikwaniritse mawonekedwe ofunikira kapena mphamvu yoyenera yopondereza.. Mphamvu yamtunduwu nthawi zambiri imatheka pogwiritsa ntchito nyundo yachitsulo kapena kukakamiza. Njira yopangira chitsulo imapangitsa kuti chitsulocho chikhale cholimba komanso chimapangitsa kuti zitsulo zisamayende bwino. Pakugwiritsa ntchito kwenikweni zigawo, kupanga koyenera kungapangitse kuti njere ziziyenda molunjika kukakamiza kwakukulu. Castings ndi zinthu zooneka ngati zitsulo zopezedwa ndi njira zosiyanasiyana zoponyera, mwanjira ina, zitsulo zamadzimadzi zosungunuka zimalowetsedwa mu nkhungu yokonzeka pothira, kuthamanga jekeseni, kuyamwa, kapena njira zina zoponya, ndipo pambuyo pozizira, chinthu chopezedwa chili ndi mawonekedwe ake, kukula, ndi ntchito pambuyo kuyeretsa ndi pambuyo processing, ndi zina.
Kugwiritsa ntchito zida zachinyengo
Kupanga kupanga ndi imodzi mwazinthu zazikulu zogwirira ntchito zomwe zimapereka makina okhwima azinthu zamakina mumakampani opanga makina. Mwa chinyengo, osati mawonekedwe a ziwalo zamakina angapezeke, koma mkati mwachitsulo chachitsulo chingathenso kusintha, ndi makina katundu ndi thupi katundu zitsulo akhoza bwino. Njira zopangira zopangira zimagwiritsidwa ntchito kwambiri popanga zida zofunika zamakina zomwe zimakhala ndi mphamvu zazikulu komanso zofunika kwambiri. Mwachitsanzo, zitsulo za jenereta za steam, rotors, zopangitsa, masamba, nsalu, zipilala zazikulu za hydraulic press, ma silinda apamwamba kwambiri, kugudubuza mphero, injini kuyaka mkati cranks, zolumikizira, zida, mayendedwe, ndipo magawo ofunikira mumakampani achitetezo cha dziko monga zida zankhondo zonse zimapangidwa mwa kupanga.
Choncho, kupanga kupanga chimagwiritsidwa ntchito kwambiri mu metallurgical, migodi, zamagalimoto, thirakitala, makina okolola, mafuta, mankhwala, ndege, zamlengalenga, zida, ndi magawo ena a mafakitale. M'moyo watsiku ndi tsiku, kupanga kupanga kumakhalanso ndi udindo wofunikira.
Ngati muli ndi mafunso ena okhudza kupanga mabawuti, pls mukumva kulumikizana nafe.
