Qaybo badan oo makaanik ah ayaa ku hoos shaqeeya is beddelka iyo culaysyada saamaynta leh sida jeexjeexa iyo foorarsiga, lakabkooda dushana waxa uu xambaarsan yahay culays ka sarreeya kan ubucda; Xaaladaha khilaafka, lakabka dusha sare ayaa si joogto ah u da'a. Sidaa darteed, shuruudaha xoojinta lakabka dusha sare ee foornada ayaa la soo hormariyaa, taas oo macnaheedu yahay in dusha sare uu leeyahay xoog sare, qallafsanaan iyo xirashada caabbinta.
Daaweynta kulaylka dusha sare ee qayb ka mid ah been-abuurka waa nidaam ku dabaqaya daaweynta kulaylka dusha sare ee workpiece si loo beddelo qaab dhismeedka iyo sifooyinka. Caadi ahaan, dusha sare wuxuu leeyahay qallafsanaan sare oo xirto iska caabin ah, halka xudunta udubdhexaadku ay weli ilaalinayso caag iyo adkaansho ku filan. Wax soo saarka, birta leh qayb gaar ah ayaa marka hore la doortay si loo hubiyo in sifooyinka farsamada ee asaasiga ah ay buuxiyaan shuruudaha, ka dibna hababka daaweynta kulaylka dusha sare ayaa lagu dabaqaa si loo xoojiyo lakabka dusha sare si loo buuxiyo shuruudaha waxqabadka. Daawaynta kulaylka dushiisa waxa loo qaybiyaa laba qaybood: deminta dusha sare iyo daawaynta kulaylka kiimikada oogada.
Deminta dusha sare ee qaybaha foornooyinka. Deminta dusha sare ee qaybaha forgings waa habka daaweynta kulaylka oo si degdeg ah u kululeeya dusha sare ee workpiece si heerkulka deminta, ka dibna si degdeg ah u qaboojiso, kaliya u oggolaanaya lakabka dusha sare si uu u helo qaab-dhismeedka la demiyo, halka xuddunta ay weli ilaalinayso qaab-dhismeedka hore loo demiyay. . Sida caadiga ah loo isticmaalo waa deminta dusha sare ee kuleyliyaha induction iyo kuleylinta dabka oo daminta. Deminta dusha sare waxaa guud ahaan loo isticmaalaa birta kaarboonka dhexdhexaadka ah iyo alwaaxyada birta kaarboonka dhexdhexaadka ah.
Deminta kuleyliyaha Induction waxay isticmaashaa mabda'a kicinta korantada si ay u keento qulqulo waaweyn oo qulqulaya oogada shaqada iyadoo loo marayo hadda beddelka ah, taasoo keenaysa in dusha sare ee foornada si degdeg ah loo kululeeyo halka xudunta udub dhexaad u tahay mid aan kululayn.
Astaamaha kuleyliyaha induction ee deminta: daminta ka dib, miraha martensite waa la safeeyey, iyo engegnaanta dusha sare waa 2-3 HRC ka sarreeya deminta caadiga ah. Waxaa jira cadaadis cadaadis badan oo haraaga ah oo ku yaala lakabka dusha sare, kaas oo gacan ka geysanaya hagaajinta xoogga daalka; Uma nugul qallafsanaanta iyo decarburization oksaydhiyaha; Si fudud loo gaaro makaanaynta iyo automation, ku habboon wax soo saarka ballaaran. Daminta kuleyliyaha induction ka dib, si loo yareeyo walbahaarka deminta iyo jajabnaanta, heerkulka hoose ee 170-200 ℃ ayaa loo baahan yahay.
Kuleylinta dusha sare ee ololku waa hab loo isticmaalo ololka gubanaya gaaska acetylene oksijiinta (ilaa 3100-3200°C) si uu si dhakhso ah u kululeeyo dusha foornooyinka ka sarreeya heerkulka isbeddelka wajiga, oo ay ku xigto deminta iyo qaboojinta.
Isla markiiba samee kulaylka heerkulka hooseeya ka dib deminta, ama isticmaal kulaylka qashinka gudaha ee foornada si aad isu-xakameyso. Habkani wuxuu heli karaa qoto dheer oo deminta 2-6 mm, oo leh qalab fudud iyo qiimo jaban, oo ku habboon hal gabal ama wax soo saar yar yar.
