Xa abantu abaninzi besiva 'ityhubhu yentsimbi engenamthungo', bacinga ukuba ngumbhobho nje ongenamthungo we weld. Yinyaniso leyo, kodwa kufana nokuthi imoto yomdyarho sisithuthi nje esinamavili amane. Ibali lokwenyani lisekwenziweni kwalo nalapho lisilela khona ukuba awuyazi into oyenzayo. Ndibone iiprojekthi ezininzi kakhulu 'ezingenamthungo' njengento yokubambisa zonke 'zomgangatho ophakamileyo', kuphela ukubaleka kwimiba yobunzima bodonga okanye ubuqhophololo obungalindelekanga kwiindawo ezithile. Asiyombumbulu yomlingo.

INyaniso eHotyo eRodiweyo kunye neeNgxaki zayo

Indlela yakudala yinkqubo eshushu yokugqobhoza-ukuthatha i-billet eqinileyo, ukuyifudumeza kwimeko yeplastiki, kwaye uyihlabe nge-mandrel. Ivakala ngokuthe ngqo, akunjalo? Umtyholi ukwiinkcukacha. Ijiko lokufudumeza libalulekile. Ukukhawuleza, kwaye ufumana ukwakheka okuziinkozo okungahambelaniyo; ucotha kakhulu, kwaye utshisa imali ngexesha lomlilo. Ndikhumbula ibhetshi yemigca yoxinzelelo oluphezulu lwehydraulic ethe yasilela kuvavanyo loxinzelelo. Umoni? Ukwehla kobushushu obungabonwanga 'kwindawo efileyo' yeziko phambi kokugqobhoza, okukhokelela kukuqina okuncinci okwenza ityhubhu ithande ukuqhekeka kancinci ngexesha lokuzoba okubandayo kamva. Siyibambile, kodwa yayisisifundo esinexabiso elikhulu ekuthembeni, kodwa ekuqinisekiseni, nkqu neeprofayile zakho ezithembekileyo zesithando somlilo.

Emva koko kukho umba wesikali. Umaleko weoksidi owenzekayo ngexesha lokufudumeza awuyongxaki nje kumphezulu. Ukuba ayisuswanga ngokufanelekileyo phambi kokuba icuthwe ngakumbi, iqengqeleka phezulu, idale iindawo ezinokubakho zokuqalisa umhlwa okanye ukudinwa. Uphela unetyhubhu edibana nokwakheka kweekhemikhali kunye namandla okuqina ephepheni kodwa unokusilela kwangaphambi kwexesha kwisicelo sokulayisha umjikelo. Zizo ezi zinto zingabonakaliyo ezahlula ityhubhu yempahla kwizinto ezithembekileyo.

Apha kulapho i-ecosystem ye-hub yemveliso ibalulekile. Ukuba kufutshane nekhonkco lokubonelela, njengesiseko semveliso ekhawulezayo e-Yongnian, e-Handan, ayithethi nje malunga nolungiselelo. Kumalunga nokufikelela kwiinkonzo ezincedisayo ezikhethekileyo-ukubona ngokuchanekileyo, iilebhu zovavanyo ezingonakalisi, iivenkile ezithile zonyango lobushushu-ezinokuphatha amanyathelo asemva kokugqobhoza ngokufanelekileyo. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., ngelixa eyaziwa ngokuba yi-fasteners, isebenza kwindawo apho olu lwazi lwe-metallurgical tubular lusemanzini, ngoko kuthetha. Indawo yabo ekufuphi neendlela ezinkulu zezothutho luncedo olusebenzayo ekuthathweni kwempahla ekrwada kunye nokuhanjiswa kwempahla egqityiweyo, ukuguqula oko kubonakala ngathi linqaku elilula lejografi libe yindleko yokwenyani kunye nokuthembeka.

Umzobo obandayo: Apho imilinganiselo iba nzulu

Ukuba ukuqengqeleka okushushu kukunika uhlobo olusisiseko olungenanto, umzobo obandayo kulapho ufumana khona imivimbo yakho echanekileyo. Oku kungenxa yezicelo apho ukunyamezela kwi-OD kunye nobukhulu bendonga buqinile-cinga iisilinda zoomatshini okanye iintlanga ezithwele. Utsala ityhubhu eshushu-eqengqelekayo ngokusebenzisa die naphezu mandrel. Yinkqubo ekhohlakeleyo kwimathiriyeli, eyenza ukuqina koxinzelelo olubalulekileyo.

Ukukhethwa kwe-lubricant apha liqabane elithuleyo kumgangatho. Ifilim ye-lubricant engalunganga ikhokelela kwi-galling, ikora umphezulu we-ID. Ndibone iityhubhu ezijongeka zigqibelele ngaphandle kodwa zinemikrwelo yangaphakathi eye yanyuka ngoxinzelelo. Kwisilinda ye-pneumatic, leyo yindlela eqinisekisiweyo yokuvuza ezantsi ngomgca. Ubuqhetseba buhlala kunyango lwangaphambili-ingubo ye-phosphate ngaphambi kokudweba kufuneka ifane ukuze ithwale i-lubricant.

Kwaye awukwazi ukungazihoyi i-annealing interpass. Zoba kakhulu ngaphandle kwe-anneal yokunciphisa uxinzelelo, kwaye imathiriyeli iba nzima ngokungasebenziyo kwaye inkenteke. Ukucwangciswa kwezi zihlomelo kusekelwe kumava kangangoko ekubaleni. Yimvakalelo yokuba uphuhla-ujonge indlela ityhubhu ephuma ngayo emva kancinane emva kokudlula, okanye utshintsho olufihlakeleyo kwisandi esisenzayo xa ubethwe. Le asiyonto yeencwadi; yi-workshop savvy.

Umbuzo we-alloy: Akunjalo nje malunga namandla

Wonke umntu utsibela kwi-ASTM A106 okanye i-A53 ye-carbon steel, okanye i-304/316 ye-stainless. Kodwa ibakala sisiqalo nje. Thatha i-A106 iBanga B. Ilungile kwiinkonzo ezininzi zobushushu obuphezulu. Kodwa ukuqina kwayo kwenotshi kumaqondo obushushu asezantsi kunokuba yinkxalabo. Sakha saba nengxaki ngomgca wokulandela umphunga kwindawo yokucoca ngexesha lengqele eqhaqhazelisa amazinyo. Umgca ngokwawo wawulungile, kodwa ityhubhu engenamthungo esetyenziselwa ukudibaniswa kwesebe elincinci, ukuhlangabezana ne-A106B spec, ibonise iimpawu zokuxhamla. Isisombululo ibingeyotyhubhu 'engcono' engenamthungo, kodwa echanekileyo-ukutshintshela kwintsimbi ecolekileyo ebuleweyo enempembelelo engcono yeCharpy yaloo macandelo athile.

Kwi-stainless, i-304 vs. 316 ingxoxo ziindaba ezindala. Ezona ndawo zinomdla ngakumbi zengxaki ziku-'phakathi-phakathi' kwezicelo. Njengomgca wokulungisa ukutya ohlamba rhoqo nge-chlorinated caustic. I-316 ingcono, kodwa ukuba umsebenzi obandayo ovela kumzobo awulandelwa sisisombululo esifanelekileyo kunye nokucima, ushiya izinto eziphathekayo, umeme i-chloride yoxinzelelo lwe-corrosion cracking. Ityhubhu idibana ne-ASTM spec, kodwa imbali yokucubungula iyayitshabalalisa. Kufuneka uthenge kwi-mill okanye iprosesa eqonda ukusetyenziswa kokuphela, kungekhona nje umgangatho.

Oku kuqhagamshela umva ekufumaneni indawo evela kwimizi-mveliso esele ikhulile. Umvelisi ofakwe apho, onje ngeZitai Fastener, uyayiqonda into yokuba ukuqinisekiswa kwezinto kungaphezulu kwephetshana. Luthotho logcino kunye nesiqinisekiso senkqubo. Ingqondo yabo yokusebenza, ebunjwe ngumthamo ophezulu, umzi-mveliso wokukhawuleza oqhutywa ngokuchanekileyo, ngokwendalo udlulela kwindlela engqongqo ekufumaneni izinto ezikrwada kunye nolawulo lwenkqubo kumacandelo afana nala. iityhubhu zentsimbi ezingenamthungo, nokuba bangabasebenzisi abasezantsi. Ukujonga iwebhusayithi yabo ku I-Zitafasteners.com, ubona ugxininiso kwiziseko zokuvelisa kunye nokulawula umgangatho-izinto eziphambili ezibaluleke kakhulu kwiimveliso ze-tubular.

Uvavanyo: Thembela, kodwa Sika kunye ne-Etch

Izatifikethi zinyanzelekile, kodwa zingumfanekiso omfutshane. Uvavanyo lwe-Hydrostatic lusemgangathweni, kodwa luvavanyo lobungqina, ayisosiqinisekiso sokusebenza kwexesha elizayo. Iimvavanyo ezityhila umlingiswa zibandakanyeka ngakumbi. Uvavanyo lwe-Ultrasonic lweziphene ze-longitudinal zixhaphakile ngoku, kodwa i-eddy current kwiziphene zomhlaba, ngakumbi kwi-ID, ingaphantsi kwaye ihlala ixabisa iindleko ezongezelelweyo kwizicelo ezibalulekileyo.

Eyona nto ityhilayo, neyonakalisayo, luvavanyo lwemacroetch. Uthatha iringi yesampulu, usike, upholise ubuso, kwaye uyiqabe ngeasidi. Oku kutyhila ukuhamba okuziinkozo, naluphi na ulwahlulo oluphakathi ukusuka kwi-billet yasekuqaleni, kwaye, ngokugqithiseleyo, ukunyaniseka kwezinto eziphathekayo apho umthungo uya kuba kwi-tube edibeneyo. Kwityhubhu yokwenyani engenamthungo, kufuneka ubone imigca yeenkozo eqhubekayo. Nakuphi na ukuphazamiseka, umgca otyhafileyo wokufakwa okanye ukuphazamiseka, ubonisa umba wokucubungula ngexesha lokubhoboza okanye ukudweba. Luvavanyo lwesidumbu olubalisa ibali lobomi bombhobho.

Siye samisela umgaqo-nkqubo wophicotho-zincwadi olungenamkhethe kumaqashiso angenayo, nkqu nakwizingqusho eziqinisekisiweyo. Ibambe ingxaki kanye apho umatshini wokusila utshintshe umboneleli wabo webhilethi kodwa awaziphuculanga ngokupheleleyo iiparamitha zabo zokugqobhoza ukuqina kwemathiriyeli entsha. Iicerts zazifana, kodwa isampulu efakiweyo ibonise ipateni yebhanti exhalabileyo. Eli qela lakhatywa kwisicelo sethu sokudinwa okuphezulu kwaye lisetyenziswe kwenye indawo. Isisindise ukusilela okukhulu kwibala.

I-Fit eSebenzisayo: IiNuances zokuSebenza kunye noKwakha

Apha kulapho ithiyori idibana khona nelathe. ityhubhu engenamthungo, ngenxa yenkqubo yokwenziwa kwayo, ihlala inobuxhakaxhaka obungaguquguqukiyo kumjikelo xa kuthelekiswa netyhubhu ye-ERW (Electric Resistance Welded), apho umthungo we-weld unokuba nobunzima obahluke kancinane. Kodwa oko akuyonyaniso yehlabathi. Ityhubhu engenamthungo etsalwa ngokubanda inoxinzelelo oluphezulu lwentsalela. Ukuba awuwusebenzisi ngokulinganayo okanye uthathe isisikeko esinzima kakhulu kwipasi enye, inokugqwesa-i-ovalize okanye igobe-njengoko uhlengahlengiso loxinzelelo. Ubuqhetseba kukuyenza irhabaxa, yiyeke ihlale, ikhulule uxinzelelo, emva koko ugqibezele umatshini. Yongeza amanyathelo, kodwa kuphela kwendlela yamalungu achanekileyo.

Ukuwelda into efanelekileyo kwityhubhu engenamthungo nako kunokuba luqilima. Ummandla ochaphazeleke bubushushu unxibelelana ne-microstructure esebenza ngokubanda. Kuqhagamshelo olubalulekileyo, kudla ngokucetyiswa ukuba uvale isiphelo setyhubhu phambi kwe-welding, nto leyo elumsebenzi uninzi lwabenzi bobuchule abawutsibayo kuba ushicilelo aluwubizi ngaphandle. Ngumsantsa ochazayo okhokelela ekungaphumeleni kwangaphambi kwexesha kwi-weld neck. Ndihlala ndisongeza inqaku kumzobo ngoku: Umatshini weld prep kwisiphelo setyhubhu edibeneyo yoqhagamshelo olunoxinzelelo.

Ifikelela koku: ukucacisa ityhubhu yentsimbi engenamthungo sisiqalo sencoko, hayi isiphelo. Yinto echazwa kakhulu ngokungabikho kwayo-ukungabikho kwe-weld seam-njengohambo oluthile lobushushu, amandla, kunye nolawulo oluyidalileyo. Ukuthembeka kwayo kuxhomekeke kwiinkcukacha ezingabonakaliyo: umoya wesithando somlilo ngexesha lokufudumala, i-lubricant chemistry ngexesha lokudweba, ixesha le-anneal. Uhlakulela intlonipho ngayo, kungekuphela nje njengento ekwiphepha lezinto eziphathekayo, kodwa njengemveliso yezobugcisa ezintsonkothileyo. Yiloo nto egqiba ukuba ingaba ngumbhobho okanye icandelo elithembekileyo.
