Ma flange oponyedwa ndi ma flange opangidwa ndi ma flange wamba, koma mitundu iwiri ya flange ndi yosiyana pamtengo.
Flange ya cast ili ndi mawonekedwe olondola ndi kukula kwake, voliyumu yaying'ono yopangira ndi mtengo wotsika, koma ili ndi zolakwika zoponya (monga pores, ming'alu ndi inclusions);Mapangidwe amkati a kuponyera ndi osauka mu streamline;Ubwino wake ndikuti ukhoza kupanga mawonekedwe ovuta kwambiri, ndipo mtengo wake ndi wochepa;
Zabodzaflangesnthawi zambiri amakhala ndi mpweya wocheperako kuposa ma flanges otayira ndipo sizovuta kudzimbirira.Ma forgings ali ndi njira yabwino, yophatikizika komanso makina abwinoko kuposa ma flange;Kupanga kolakwika kumabweretsanso mbewu zazikulu kapena zosagwirizana ndi ming'alu yowumitsa, ndipo mtengo wopangira umakhala wapamwamba kuposa wa flange.Ma forging amatha kupirira kumeta ubweya wambiri komanso mphamvu zolimba kuposa zoponya.Ubwino wake ndikuti mawonekedwe amkati ndi ofanana ndipo palibe zolakwika zovulaza monga pores ndi inclusions pakuponya;
Kusiyana pakati pa cast flange ndi forged flange kumatengera kupanga.Mwachitsanzo, centrifugal flange ndi mtundu wa flange.Centrifugal flange ndi ya njira yolondola yopangira kupanga flange.Poyerekeza ndi kuponyedwa kwa mchenga wamba, kuponyera kotereku kumakhala ndi mawonekedwe abwino kwambiri komanso abwinoko, ndipo sikophweka kukhala ndi zovuta monga mawonekedwe otayirira, dzenje la mpweya ndi trachoma.
Tiyeni timvetsetse momwe kupanga flange yabodza kachiwiri: njira yopangira zinthu nthawi zambiri imakhala ndi njira zotsatirazi, zomwe ndi kusankha ma billet blanking apamwamba kwambiri, kutentha, kupanga, ndi kuziziritsa pambuyo popanga.
Njira yopangira zojambulajambula imaphatikizapo kupangira kwaulere, kupangira kufa komanso kupanga mafilimu.Pakupanga, njira zosiyanasiyana zopangira zimayenera kusankhidwa molingana ndi kukula kwa mtundu wa forging ndi batch yopanga.Kupanga kwaulere kumakhala ndi zokolola zochepa komanso ndalama zazikulu zopangira makina, koma chidacho ndi chosavuta komanso chosunthika, motero chimagwiritsidwa ntchito kwambiri popanga chidutswa chimodzi ndi ma forging ang'onoang'ono okhala ndi mawonekedwe osavuta.Zida zopangira zaulere zimaphatikizapo nyundo ya mpweya, nyundo ya mpweya ndi makina osindikizira a hydraulic, omwe ali oyenera kupanga ma forging ang'onoang'ono, apakatikati ndi akulu.Die forging imakhala ndi zokolola zambiri, ntchito yosavuta, ndipo ndiyosavuta kuzindikira makina ndi makina.Mafa forgings ali ndi mawonekedwe olondola kwambiri, chilolezo chochepa cha makina, komanso kugawa koyenera kwa ma fiber, komwe kumatha kupititsa patsogolo moyo wautumiki wa magawo.
1 、 Basic process of forging free: pakupanga kwaulere, mawonekedwe a forging amapangidwa pang'onopang'ono ndi njira zina zosinthira.Njira zoyambira zopangira kwaulere zimaphatikizapo kukhumudwitsa, kujambula, kukhomerera, kupindika ndi kudula.
1. Kukhumudwitsa ndi njira ya opaleshoni yopangira chopanda kanthu potsatira njira ya axial kuti muchepetse kutalika kwake ndikuwonjezera gawo lake.Izi nthawi zambiri zimagwiritsidwa ntchito popanga ma giya osalembapo ndi zina zopangira ma disc.Kukhumudwa kumagawidwa kukhala kukhumudwitsa kwathunthu ndi kukhumudwitsa pang'ono.
2. Kujambula ndi njira yowonongeka yomwe imawonjezera kutalika kwa chopanda kanthu ndikuchepetsa gawo la mtanda.Nthawi zambiri amagwiritsidwa ntchito kupanga magawo a shaft, monga lathe spindle, ndodo yolumikizira, etc.
3. Kukhomerera Mchitidwe wokhomerera poboola kapena kubowola popanda kanthu ndi nkhonya.
4. Njira yokhotakhota yopinda chopanda kanthu pakona kapena mawonekedwe.
5. Njira yopangira momwe gawo limodzi la chosowacho limazungulira pakona inayake yokhudzana ndi inzake.
6. Kupanga njira yodula ndikugawanitsa opanda kanthu kapena kudula mutu.
2, Kufa popanga;Dzina lonse la kufa kwa forging ndi kupanga chitsanzo, komwe kumapangidwa poyika chotenthetsera chopanda kanthu mu kufa kokhazikika pazida zopangira zida.
1. Njira yayikulu yopangira zida zakufa: kutseka, kutenthetsa, kufota, kufota komaliza, kukhomerera, kudula, kutenthetsa, kuloza.Njira zodziwika bwino zimaphatikizapo kusokoneza, kujambula, kupindika, kukhomerera ndi kupanga.
2. Zida zopangira zida wamba Zida zopangira zida zakufa zimaphatikizanso nyundo, makina osindikizira otentha, makina opukutira, makina osindikizira, ndi zina zambiri.
3, Kudula flange;Dulani mwachindunji mkati ndi kunja ndi makulidwe a flange ndi machining allowance pa mbale yapakati, ndiyeno konza dzenje la bawuti ndi mzere wamadzi.Choncho flange yopangidwa imatchedwa cutting flange.Kutalika kwakukulu kwa flange yotere kumangokhala m'lifupi mwa mbale yapakati.
4, adagulung'undisa flange;Njira yogwiritsira ntchito mbale yapakatikati podula zingwe ndikuzigudubuza mozungulira imatchedwa coiling, yomwe imagwiritsidwa ntchito kwambiri popanga ma flange akuluakulu.Pambuyo pakugubuduza bwino, kuwotcherera kudzachitika, ndiyeno kuwotcherera kudzachitika, ndiyeno kukonzanso kwamadzi ndi dzenje la bawuti kudzachitika.
Miyezo yodziwika bwino ya flange: American standard flangeASME B16.5, ASME B16.47
