Bakin karfe flanges ana amfani da ko'ina a kowane fanni na rayuwa saboda da kyau bayyanar, high zafin jiki da kuma high matsa lamba juriya, lalata juriya da sauran halaye. Duk da haka, mutane da yawa har yanzu suna da matsaloli da yawa wajen sarrafa bakin karfe flanges. A yau za mu yi magana game da yadda za a magance matsalolin da ke faruwa a cikin tsarin rashin sarrafa bakin karfe.
A sarrafa nabakin karfe flangeyana buƙatar sani da kula da wasu matsalolin:
1. Weld hadin gwiwa lahani: da weld lahani na bakin karfe flange ne in mun gwada da tsanani. Idan an yi amfani da goge na inji na hannu don gyara shi, alamomin niƙa za su haifar da rashin daidaituwa kuma suna shafar bayyanar;
2. m polishing da passivation: bayan manual polishing da polishing, yana da wuya a cimma uniform da uniform magani sakamako ga workpieces da babban yanki, kuma ba zai iya samun manufa uniform surface. Haɗin flange mai wuya ko haɗin haɗin flange yana nufin haɗin da za a iya cirewa na flange, gasket da kusoshi azaman rukuni na tsarin rufewa.
Flange na bututu yana nufin flange da aka yi amfani da shi don yin bututun bututun a cikin na'urar bututun, da mashigin ciki da na kayan aiki lokacin amfani da kayan aiki. Akwai ramuka akanflange, da kusoshi suna sa flanges biyu sun haɗa sosai. Butt-welding flange wani nau'i ne na kayan aiki na bututu, wanda ke nufin flange tare da wuyan wuyansa da zagaye na bututu da kuma haɗawa tare da waldawar bututu. Ba shi da sauƙi a gyara, an rufe shi da kyau kuma ana amfani da shi sosai. Ya dace da bututun da ke da manyan sauye-sauye a cikin matsa lamba ko zazzabi ko bututun da ke da zafi mai zafi, matsa lamba da ƙananan zafin jiki. Amfanin shi ne cewa farashin yana da arha mai arha, kuma matsa lamba na ƙima baya wuce 2.5MPa;
Hakanan ana amfani dashi a cikin bututun jigilar kayayyaki masu tsada, masu ƙonewa da fashewar abubuwa, tare da matsa lamba na kusan PN16MPa. Hakanan akwai rashin amfaninsa, kamar tsadar lokutan aiki da kayan taimako;
3. Scratches da wuya a cire: gaba ɗaya pickling da passivation, sinadarai lalata ko electrochemical lalata zai faru da kuma tsatsa zai faru a gaban da lalata kafofin watsa labarai (yanke abubuwa), da carbon karfe, spatter da sauran ƙazanta manne ga saman bakin karfe. saboda scratches da walda spatter ba za a iya cire;
Don haka yadda ake magance matsalarbakin karfe flangesarrafa?
1. Zaɓi blanking, sannan shigar da tsari na gaba. Daban-daban workpieces a cikin bakin karfe flange aiki shigar da daidai tsari bisa ga aiki bukatun;
2. Lokacin lankwasawa, kayan aiki da tsagi da aka yi amfani da su don lankwasawa za a ƙayyade bisa ga girman kan zane da kauri na bakin karfe 304 bututun ƙarfe mara nauyi. Makullin zaɓi na ƙwanƙwasa na sama shine don kauce wa lalacewar lalacewa ta hanyar karo tsakanin flange da kayan aiki (bayani: wani muhimmin sashi na kwatankwacin) (za'a iya amfani da nau'i daban-daban na mold na sama a cikin wannan samfurin). Zaɓin ƙananan ƙira an ƙaddara bisa ga kauri na farantin. Lokacin haɗa famfo da bawul na masana'anta na flange tare da bututun, sassan waɗannan kayan aikin ana kuma sanya su cikin sifofin flange masu dacewa, wanda kuma aka sani da haɗin flange.
3. Domin weld da tabbaci, naushi karo a kan workpiece da za a welded, wanda zai iya sa karo lamba tare da lebur farantin ko'ina kafin ikon-on waldi don tabbatar da daidaito na dumama a kowane batu, da kuma ƙayyade waldi matsayi. , wanda ake buƙatar waldawa. Daidaita lokacin latsawa kafin lokaci, lokacin riƙe matsi, lokacin kulawa, da sauran lokacin hutawa don tabbatar da cewa kayan aikin za'a iya yin waldi da ƙarfi.
