Flange ntau lawm txheej txheem
Cov txheej txheem ntau lawm yog muab faib ua plaub hom: forging, casting, txiav thiab dov.
(1) Cam khwb cia flange thiab forged flange
Cov flange cam khwb cia muaj qhov zoo thiab qhov loj ntawm qhov khoob, qhov ntim me me thiab tus nqi qis, tab sis muaj qhov tsis xws luag (porosity, tawg, suav nrog); lub koom haum sab hauv ntawm lub casting yog tsawg streamlined (yog hais tias nws yog ib feem, lub streamlined zoo yog txawm phem dua);
Forged flanges feem ntau muaj cov ntsiab lus qis dua li cov flanges cam khwb cia thiab tsis yooj yim rau xeb, cov forgings yog streamlined, cov qauv yog qhov ntom ntom, thiab cov khoom siv kho tshuab zoo dua li cam khwb cia flanges;
Cov txheej txheem forging tsis raug kuj tseem yuav ua rau cov nplej loj lossis tsis sib xws, cov kab nrib pleb hnyav, thiab cov nqi forging yog siab dua li cov flanges.
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 forgings yog tias cov qauv sab hauv yog sib xws, thiab tsis muaj teeb meem tsis xws luag xws li pores thiab inclusions hauv casting;
Qhov txawv ntawm casting flanges thiab forging flanges yog txawv los ntawm cov txheej txheem ntau lawm. Piv txwv li, centrifugal flanges yog ib hom casting flanges.
Centrifugal flanges muaj nyob rau hauv txoj kev casting los tsim flanges. Piv nrog rau cov xuab zeb zoo tib yam castings, hom casting no muaj ntau cov qauv zoo dua thiab txhim kho zoo, thiab tsis muaj teeb meem xws li lub koom haum xoob, pores, thiab trachoma.
Ua ntej ntawm tag nrho cov, peb yuav tsum to taub yuav ua li cas lub centrifugal flange yog tsim, txheej txheem txheej txheem thiab cov khoom ntawm centrifugal casting los ua ca vuam flange, uas yog yus muaj los ntawm cov txheej txheem nram qab no cov kauj ruam:
① Muab cov khoom siv raw khoom xaiv rau hauv qhov nruab nrab zaus hluav taws xob qhov cub rau smelting, kom lub molten steel kub mus txog 1600-1700 degree ;
②Preheat cov pwm hlau rau 800-900 degree kom tswj tau qhov kub thiab txias;
③ Pib lub centrifuge thiab txhaj cov hlau molten hauv kauj ruam ① rau hauv cov pwm preheated hlau hauv kauj ruam ②;
④Cov castings yog txias txias rau 800-900 degree rau 1-10 feeb;
⑤ Txias nrog dej kom ze rau qhov kub thiab txias, demould thiab tshem tawm cov casting.
Cia peb saib ntawm cov txheej txheem tsim khoom ntawm forged flanges:
Cov txheej txheem forging feem ntau yog tsim los ntawm cov txheej txheem hauv qab no, uas yog, xaiv cov pob zeb zoo rau kev blanking, cua sov, sib sau, thiab txias tom qab forging. Forging txheej txheem muaj xws li dawb forging, tuag forging thiab fetal membrane forging. Thaum lub sij hawm tsim khoom, ntau txoj kev forging raug xaiv raws li qhov zoo ntawm forgings thiab cov khoom siv ntau lawm.
Dawb forging muaj tsawg tsim tau thiab loj machining pub, tab sis cov cuab yeej yog yooj yim thiab ntau yam, 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 xws li cua rauj, chav cua-cua rauj thiab hydraulic xovxwm, thiab lwm yam, uas haum rau kev tsim cov me me, nruab nrab thiab loj forgings. Tuag forging muaj cov khoom lag luam siab, kev ua haujlwm yooj yim, thiab kev siv tshuab yooj yim thiab automation. Tuag forgings muaj qhov siab qhov tseeb, me me machining nyiaj pub dawb, thiab ntau qhov tsim nyog faib cov qauv fiber ntau, uas tuaj yeem txhim kho lub neej kev pab cuam ntawm qhov chaw.
Cov txheej txheem yooj yim ntawm kev forging dawb: Thaum lub sij hawm pub dawb forging, cov duab ntawm forging yog maj mam forged los ntawm 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. Upsetting Upsetting yog ib qho txheej txheem kev lag luam uas cov khoom siv raw yog forged nyob rau hauv axial kev taw qhia kom txo nws qhov siab thiab nce nws qhov cross-section. Cov txheej txheem no feem ntau yog siv rau forging iav blanks thiab lwm yam disc-shaped forgings. Upsetting muab faib ua ob hom: tag nrho upsetting thiab ib nrab forging.
2. Elongation Elongation yog txheej txheem forging uas ua rau kom qhov ntev ntawm qhov khoob thiab txo qhov ntu ntu. Nws feem ntau yog siv los tsim cov ncej blanks, xws li tshuab dhos spindles, txuas rods, thiab lwm yam.
3. Punching yog txheej txheem forging uas siv cov xuas nrig ntaus los ntawm qhov los yog tsis dhau qhov ntawm qhov khoob.
4. Bending Ib txheej txheem forging uas lub billet yog khoov rau hauv ib lub kaum ntse ntse lossis cov duab.
5. Torsion yog txheej txheem forging nyob rau hauv uas ib feem ntawm lub billet rotates ntawm ib lub kaum sab xis txheeb ze rau lwm qhov.
6. Cov txheej txheem forging ntawm kev txiav thiab faib cov blanks lossis txiav taub hau.
(2) Tuag forging
Lub npe tag nrho ntawm kev tuag forging yog qauv forging, uas yog tsim los ntawm kev tso cov rhuab billet nyob rau hauv ib tug forging tuag tsau 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 thiab skinning, trimming, quenching thiab tempering, tua peening. Cov txheej txheem feem ntau suav nrog kev ntxhov siab, kos duab, khoov, xuas nrig ntaus, thiab sib sau.
2. Cov cuab yeej siv feem ntau siv tuag forging Cov cuab yeej siv feem ntau suav nrog tuag forging rauj, kub tuag forging xovxwm, lub tshuab forging tiaj tus thiab kev sib txhuam xovxwm.
Nyob rau hauv layman cov ntsiab lus, qhov zoo ntawm forged flanges yog zoo dua, feem ntau tsim los ntawm tuag forging, nrog zoo siv lead ua qauv thiab siab zog. Tau kawg, tus nqi kuj tseem kim dua.
Seb nws yog cam khwb cia flange los yog forged flange, nws yog ib qho kev tsim khoom rau flanges. Nws nyob ntawm qhov yuav tsum tau muaj zog ntawm cov khoom siv. Yog tias qhov xav tau tsis siab, tig flanges kuj siv tau.
(3) Txiav flange
Lub puab thiab sab nraud diameters thiab thicknesses ntawm lub flange yog ncaj qha txiav rau hauv nruab nrab phaj, thiab ces cov ntsia liaj qhov rooj qhov thiab cov kab dej yog tiav. Cov flanges tsim nyob rau hauv txoj kev no hu ua txiav flanges, thiab txoj kab uas hla loj ntawm cov flanges yog txwv los ntawm qhov dav ntawm nruab nrab phaj.
(4) Rolled flange
Cov txheej txheem ntawm kev txiav cov nplais nrog lub phaj nruab nrab thiab tom qab ntawd dov mus rau hauv lub voj voog yog hu ua dov, uas feem ntau yog siv los tsim cov flanges loj. Tom qab lub yob ua tiav, nws yog welded, ces flattened, thiab ces ua tiav nyob rau hauv tus txheej txheem ntawm dej kab thiab ntsia liaj qhov rooj qhov.
