Cov txheej txheem ntau lawm yog muab faib ua forging, casting, txiav thiab dov. (1) Casting flange thiab forged flange casting flange, cov duab dawb paug thiab qhov loj me yog qhov tseeb, kev ua haujlwm me me, tus nqi qis, tab sis muaj qhov tsis xws luag (porosity. Cracks. Inclusions); Lub koom haum sab hauv ntawm lub casting yog tsis zoo nyob rau hauv streamlining (yog hais tias nws yog ib feem, lub streamlining yog phem dua); Lub forged flange feem ntau qis dua cov pa roj carbon monoxide cam khwb cia flange thiab tsis yooj yim rau xeb, lub forging yog streamlined, lub koom haum yog qhov ntom ntom, thiab cov khoom siv kho tshuab zoo dua li cov cam khwb cia flange; Cov txheej txheem forging tsis tsim nyog kuj tseem yuav tshwm sim loj lossis tsis sib xws, qhov tshwm sim ntawm kev sib tsoo tawg, tus nqi forging yog siab dua casting flange.
Forgings tuaj yeem tiv taus siab dua shear thiab tensile zog dua li castings. Qhov zoo ntawm casting yog tias nws tuaj yeem tsim cov duab ntau dua thiab tus nqi qis dua; Qhov kom zoo dua ntawm forging yog tias lub koom haum sab hauv yog sib xws, thiab tsis muaj teeb meem tsis xws luag xws li pores thiab inclusions hauv castings. Los ntawm cov txheej txheem tsim khoom kom paub qhov txawv ntawm qhov sib txawv ntawm qhov flange thiab forged flange, xws li centrifugal flange yog ib hom casting flange. Centrifugal flange yog ib txoj hauv kev zoo tshaj plaws los tsim cov flange, qhov casting yog qhov zoo dua li cov xuab zeb zoo tib yam, qhov zoo yog txhim kho ntau, thiab nws tsis yooj yim rau muaj teeb meem xws li cov ntaub so ntswg, porosity, trachoma thiab lwm yam. Ua ntej ntawm tag nrho cov, peb yuav tsum to taub yuav ua li cas lub centrifugal flange yog tsim, cov txheej txheem txoj kev thiab cov khoom ntawm lub centrifugal casting tiaj-welded flange, uas yog yus muaj los ntawm cov khoom ua tiav los ntawm cov txheej txheem hauv qab no: ① Cov khoom siv raw khoom xaiv steel rau hauv nruab nrab zaus hluav taws xob rauv melting, kom qhov kub ntawm cov hlau molten mus txog 1600-1700 degree ; ② Cov pwm hlau yog pre-rhuab mus rau 800-900 degree kom tswj tau qhov kub thiab txias; ③ Pib lub centrifuge thiab txhaj cov hlau molten nyob rau hauv kauj ruam 1 rau hauv kauj ruam 2 kom preheat lub hlau pwm; ④ Lub casting yog ib txwm txias rau 800-900 degree rau 1-10 feeb; ⑤ Txias nrog dej kom ze rau chav tsev kub, tshem tawm cov casting.
Cia peb nkag siab cov txheej txheem ntawm forged flange: cov txheej txheem forging feem ntau yog tsim los ntawm cov txheej txheem hauv qab no, uas yog, xaiv cov khoom zoo tshaj plaws, cua sov, tsim, thiab txias tom qab forging. Cov txheej txheem forging suav nrog dawb forging, tuag forging thiab membrane forging. Thaum tsim khoom, xaiv cov txheej txheem sib txawv raws li qhov loj ntawm forging zoo thiab cov khoom siv ntau lawm. Dawb forging muaj cov khoom lag luam tsawg thiab kev ua haujlwm loj, tab sis cov cuab yeej yooj yim thiab ntau yam yog qhov loj, yog li nws yog dav siv rau forging ib leeg thiab me me batch forgings nrog cov duab yooj yim. Cov khoom siv forging pub dawb muaj cua rauj, chav cua-cua rauj thiab hydraulic xovxwm, feem, haum rau me me, nruab nrab thiab loj forging ntau lawm. Tuag forging productivity yog siab, lub lag luam yog yooj yim, yooj yim kom paub mechanization thiab automation. Qhov tseeb qhov tseeb ntawm qhov tuag forging yog qhov siab, qhov nyiaj siv ua haujlwm me me, thiab cov qauv fiber ntau faib ntawm qhov chaw forging yog qhov tsim nyog, uas tuaj yeem txhim kho kev pab cuam lub neej ntawm qhov chaw.
Cov txheej txheem yooj yim ntawm kev forging dawb: Hauv kev forging dawb, cov duab ntawm forging yog maj mam forged rau hauv qhov khoob los ntawm qee cov txheej txheem deformation. Cov txheej txheem yooj yim ntawm kev forging pub dawb suav nrog kev ntxhov siab, kos duab, xuas nrig ntaus, khoov thiab txiav. 1. Kev ntxhov siab ntxhov siab yog cov txheej txheem kev ua haujlwm ntawm forging raw billet raws axis kom txo nws qhov siab thiab nce nws qhov hla. Cov txheej txheem no feem ntau yog siv rau forging iav billets thiab lwm yam disc-shaped forgings. Muaj ob hom kev chim siab: tag nrho kev chim siab thiab ib nrab chim siab. 2. Kev kos duab ntev yog cov txheej txheem forging uas ua rau kom qhov ntev ntawm lub billet thiab txo qhov seem, uas feem ntau yog siv los tsim cov ncej seem dawb paug, xws li tshuab dhos spindle thiab txuas pas nrig. 3. Cov txheej txheem forging ntawm xuas nrig ntaus tawm los ntawm lub qhov lossis los ntawm qhov ntawm qhov khoob nrog punches. 4. Bending Forging txheej txheem uas khoov lub billet rau hauv ib lub kaum sab xis lossis cov duab. 5. Twist cov txheej txheem forging uas tig ib feem ntawm qhov khoob ntawm lub kaum sab xis mus rau lwm qhov. 6. Forging txheej txheem ntawm kev txiav thiab faib billet los yog txiav tawm lub taub hau.
(2) Tuag forging tuag forging yog hu ua qauv forging, thiab cov rhuab blanks muab tso rau hauv forging tuag tsau rau ntawm cov khoom forging tuag. 1. Cov txheej txheem ntawm kev tuag forging Tuag forging txheej txheem: blanking, cua sov, pre-forging, zaum kawg forging, xuas nrig ntaus ntawm daim tawv nqaij, txiav ntug, txias, tua peening. Cov txheej txheem feem ntau suav nrog kev ntxhov siab, kos duab, khoov, xuas nrig ntaus thiab sib sau. 2. Common tuag forging khoom Common tuag forging khoom muaj xws li tuag forging rauj, kub tuag forging xovxwm, ca forging tshuab thiab kev sib txhuam xovxwm. Feem ntau hais lus, qhov zoo ntawm forged flange zoo dua, feem ntau tsim los ntawm kev tuag forging, cov qauv siv lead ua zoo, lub zog siab, thiab tau kawg tus nqi kim dua. Txawm hais tias cam khwb cia flange los yog forged flange yog ib hom kev tsim flange, nyob ntawm seb lub zog yuav tsum tau ua ntawm cov khoom uas yuav tsum tau siv, yog tias cov kev xav tau tsis siab, koj tuaj yeem xaiv tig flange.
(3) Txiav flange ncaj qha txiav tawm lub disc nrog lub puab thiab sab nraud txoj kab uas hla thiab thickness ntawm lub flange nrog cov nqi ua nyob rau hauv nruab nrab phaj, thiab ces ua cov ntsia liaj qhov rooj qhov thiab dej kab. Lub flange tsim nyob rau hauv txoj kev no yog hu ua txiav flange, thiab lub siab tshaj plaws txoj kab uas hla ntawm xws li flange yog txwv los ntawm qhov dav ntawm nruab nrab phaj. (4) Winding flange Cov txheej txheem ntawm kev txiav slivers nrog nruab nrab phaj thiab tom qab ntawd dov mus rau hauv lub voj voog yog hu ua winding, uas feem ntau yog siv los tsim cov flanges loj. Tom qab ua tiav dov, vuam yog ua, thiab tom qab ntawd flattening yog ua, thiab cov txheej txheem ntawm waterline thiab bolt qhov yog tiav.
