Fundo kuwotcherera manja

Fundo kuwotcherera ndi manja ake, nthawi zambiri, ntchito yopanga mndandanda wa magawo ofanana kapena kupanga mbali welded olowa ndi miyeso lalikulu. mfundo zake lagona Kutentha wa zitsulo kudzera mwa m'kupita panopa mu izo, njira panopa ali si yunifolomu. Fundo kuwotcherera manja amafuna wamphamvu kwambiri mphamvu kotunga kuposa zinachitikira Mwachitsanzo, Arc kuwotcherera, chifukwa ngakhale mu makina yaing'ono pini mtundu wa ntchito mphamvu panopa amayezedwa zikwi mikuza mawu, osanenapo makina akuluakulu. Nthawi zambiri ntchito sitepe-pansi thiransifoma ndi sekondale windings koyilo ndi lalikulu kusintha chiŵerengero monga gwero mphamvu.

Malo kuwotcherera - kuwotcherera a mbali mwa yochepa zimachitika. Mphamvu panopa wa yotsirizira akhale lalikulu, ndi voteji - yaing'ono. Ndi kusankha zimachitika nthawi empirically zofunika kuganiza zimene makulidwe a chitsulo china chotulutsa.

Kodi kulankhula kuwotcherera ndi manja ake? Izi amafuna zida wapadera. Iwo akhoza kukhala paokha, koma china chotulutsa mbali yaing'ono ndi wopyapyala. Amakhala ndi zigawo ziwiri - ndi magetsi ndi makina. Ngati mwaganiza kudzimvera kusonkhana makina kuwotcherera, izo zikuchitika, kusamalira kwambiri kudalilika polumikizana, kwa iwo kudzadalira mmene khalidwe liti funsani kuwotcherera. Zipangizo zothandiza kupanga chipangizo chotere, unit kulamulira, msonkhano kukhudzana ndi kuwotcherera thiransifoma.

Nthawi zambiri, kukana kuwotcherera ikuchitika ndi manja awo kuti kulumikiza kulowererana mbali pepala zitsulo, pawiri yokha amachitidwa pa mfundo ali pafupi. Billets kukonzekera ntchito, ndi unkagunda maelekitirodi, kuti ndiye akuchititsa panopa mkulu panopa therethrough. M'dera kukhudzana adzakhala zochepa padziko roughness. Malo imene mipita panopa, kulumikiza iwo, ngalande. Iwo anali usavutike, kotero kuti pakati mfundo ya aliyense wa iwo ayamba kusungunuka. Zikuoneka pakati pa kali kugwirizana awiri. Amphamvu Kutentha facilitates mapindikidwe pulasitiki kuti roughness ndi kusintha mphamvu ya mawu amene akusowekapo zakuthupi.

Zimenezi angathe kuchitidwa monga ndi chitsulo Sungunulani (kukana) ndi wopanda (reflow). Pamwamba pa workpiece n'kofunika mosamala kukonzekera. Izi ndi zofunika makamaka pofuna pachilichonse za magetsi m'mphepete. Nthawi zambiri, ankakonda maphatikizidwe kuwotcherera kuposa kukana kuwotcherera, chifukwa sikutanthauza maphunziro. komanso zimathandiza kuti kuphatikiza mbali zosiyanasiyana zitsulo ndi lalikulu.

Mbali malo kuwotcherera kuti zoipazi kunachitika ndondomeko, kumaonjezera kachulukidwe ndi mphamvu ya china chotulutsa lapansi. Adakhumba mode opaleshoni amusankha malinga unit mphamvu. The yaitali Kutentha nthawi, nthawi yozizira, ndipo chotero, chindichepere akulimbana. mode zofewa ntchito kuwotcherera steels mkulu mpweya, monga iwo sachedwa oipa, zikubweretsa mapangidwe kupsyinjika. Imakhala kwa kuwonjezeka mu zitsulo Kutentha nthawi. Austenitic zitsulo ndi welded mu mode imene anaigwira mwakhama amapewa kutenthedwa padziko.
