Mitundu ya Welded Splice Joint ndi Njira Zolumikizira

Ma rivets nthawi zambiri amagawidwa motere:

• Ma rivets oyendetsedwa ndi moto: Ma rivets omwe amayendetsedwa m'malo otentha
• Gulani ma rivets: Ma rivets omwe amayikidwa mu msonkhano
• Masewera a Field rivets: Ma rivets omwe amayikidwa pa tsamba/munda.

Ma rivets otenthedwa ndi ozizira: Popeza kuthamanga kwakukulu kumafunika kupanga mutu pa kutentha kwapakati pamtundu uwu wa rivet ndi wochepa.

ubwino: Kutumiza kwamphamvu kodalirika, kulimba kwabwino komanso pulasitiki, kuyang'ana kosavuta kwamtundu, kukana bwino kuzinthu zosunthika

kuipa: dongosolo zovuta, zitsulo mtengo ndi ntchito

Ngakhale pali njira zitatu zolumikizirana ndi uinjiniya wamapangidwe azitsulo, kuwotcherera ndiye njira yayikulu pakupangira magawo omangika. Ubwino wa zinthu zowotcherera zimagwirizana ndi mtundu wazinthu zomwe zimagwiritsidwa ntchito pomanga nyumba yonse. Choncho, kuwotcherera ayenera mokwanira welded, sayenera kuphonya kuwotcherera.

Njira Zazikulu Zolumikizirana

Zomangamanga zachitsulo zitha kugawidwa m'mapangidwe owotcherera, zomangika ndi zomangika molingana ndi njira zolumikizirana. Njira zazikulu zolumikizirana ndi kamangidwe kachitsulo kamakono ndi kuwotcherera, bolting ndi kugwirizana kwa rivet.

Kutulutsa

Kulumikiza kuwotcherera ndi njira yofunika kwambiri yolumikizira zida zachitsulo pakadali pano, yomwe imadziwikanso kuti kuwotcherera, yomwe imagwiritsa ntchito kutentha kwambiri, kutentha kapena kuthamanga kwambiri kuphatikiza ukadaulo wazitsulo. Pali njira zambiri zowotcherera, monga kuwotcherera kwa arc m'manja, kuwotcherera kwa arc pansi pamadzi, kuwotcherera kwa tungsten TIG, kuwotcherera kwachitsulo cha gasi, etc. Zomwe zimagwiritsidwa ntchito zimatengera zosowa zenizeni.

ubwino: dongosolo losavuta, kupulumutsa zinthu, kukonza kosavuta, ndi ntchito zokha zitha kutengedwa,

kuipa: High zofunika zipangizo, kuwotcherera adzachititsa mapindikidwe structural ndi kupsyinjika yotsalira mu zone kutentha bwanji, kotero mu ndondomeko kuwotcherera, ayenera kulimbikitsidwa kupewa kuwotcherera kupunduka chilema ndi kukonza pa nthawi.

Kuwerenga Kwambiri: Structural Steel Welding

bawutied Connection

Kulumikizana kwa bolted ndi njira yowonjezereka yolumikizirana, yomwe ndikugwiritsa ntchito mabawuti kudutsa mabowo a magawo awiri omwe alumikizidwa, kenaka amayika ma washers, ndikumangitsa mtedza. Njirayi ili ndi ubwino wa msonkhano wosavuta komanso wofulumira ndipo ingagwiritsidwe ntchito pogwirizanitsa zomangamanga ndi zowonongeka.

Choyipa ndichakuti gawo la gawoli ndi lofooka komanso losavuta kumasula. Pali mitundu iwiri yamalumikizidwe a bawuti: zolumikizira wamba za bawuti ndi zolumikizira zolimba kwambiri. Kuphatikizika kophatikizana kwa ma bolts amphamvu kwambiri ndi apamwamba kuposa ma bolts wamba, ndipo kulumikizana kwamphamvu kwamphamvu kumatha kuchepetsa kufowoka kwa mabowo a misomali pazigawo, kotero amagwiritsidwa ntchito kwambiri.

Pakati pawo, pali mabawuti wamba ndi mabawuti amphamvu kwambiri. Maboti wamba nthawi zambiri amapangidwa ndi chitsulo wamba cha carbon structural popanda kutentha. Maboti amphamvu kwambiri nthawi zambiri amapangidwa ndi chitsulo chapamwamba kwambiri cha carbon structural steel kapena alloy structural steel, chomwe chimafunika kuzimitsidwa ndikupsya mtima kuti chiwongolero champhamvu chamakina chitheke.

Mphamvu yayikulu imagawidwa m'makalasi a 8.8, giredi 10.9, ndi magiredi 12.9. Kuchokera ku kalasi ya mphamvu: Maboti amphamvu kwambiri amagwiritsidwa ntchito m'magulu awiri amphamvu a 8.8S ndi 10.9S. Maboti wamba nthawi zambiri amakhala ndi giredi 4.4, 4.8, 5.6 ndi 8.8. Mabawuti amphamvu kwambiri amagwiritsa ntchito mphamvu yolimbikira isanakhazikike ndipo amatumiza mphamvu yakunja ndi kukangana, ndipo mabawuti wamba amatumiza mphamvu yometa ubweya ndi kukana kukameta ubweya wa bawuti ndi kukakamiza kwa khoma.

Bawuti wamba cmgwirizano

ubwino: kutsitsa kosavuta ndi kutsitsa, zida zosavuta

kuipa: Bolt ikakhala yolondola, siyenera kuyang'aniridwa. Pamene kulondola kwa bawuti kuli kwakukulu, kukonza ndi kukhazikitsa kumakhala kovuta ndipo mtengo wake ndi wapamwamba.

Kulumikizana kolimba kwambiri kwa bawuti

ubwino: Mtundu wa mkangano umakhala ndi kumeta ubweya waung'ono komanso magwiridwe antchito abwino, makamaka oyenera kumapangidwe okhala ndi katundu wotsatira. Kuthekera kwamtundu wonyamula kupanikizika ndikwapamwamba kuposa mtundu wa mikangano, ndipo kugwirizanako ndi kophatikizana.

kuipa: Kukangana kwapamwamba kumathandizidwa, kuyikapo kumakhala kovuta pang'ono, ndipo mtengo wake ndi wokwera pang'ono; kumeta ubweya wa kulumikiza kupanikizika ndi kwakukulu, ndipo sikuyenera kugwiritsidwa ntchito muzinthu zomwe zimanyamula katundu wosinthasintha.

Dziwani zambiri za Mitundu Yamalumikizidwe Pamapangidwe Azitsulo

Kugwirizana kwa Rivet

Kulumikizana kosasunthika kosasunthika komwe kumagwiritsa ntchito ma rivets kulumikiza zigawo ziwiri kapena zingapo (nthawi zambiri mbale kapena mbiri) palimodzi, zomwe zimatchedwa riveting. Kulumikizana kwa Rivet kuli ndi mawonekedwe aukadaulo wosavuta, kulumikizana kodalirika komanso mtundu wosachotsedwa.
