Dab tsi cov ntsiab lus muaj nyob rau hauv Jianzhi malleable steel yeeb nkab fittings?
Jun 09, 2023
Nrog rau txoj kev loj hlob sai ntawm kuv lub teb chaws kev lag luam, qhov kev thov rau malleable hlau yeeb nkab fittings (feem ntau hu ua malleable steel yeeb nkab fittings) rau cov dej, roj thiab roj nkag tau nce ib hnub dhau ib hnub, thiab cov kev xav tau rau nws qhov zoo kuj tau nce siab dua. .
Kev siv tau ntawm Jianzhi malleable steel yeeb nkab fittings rau qhov loj ntawm castings, castings tsim los ntawm qhov tsis zoo siab compact casting, tsis zoo li hlau nplaum casting, yog txwv los ntawm qhov loj ntawm qhov sib nqus ncej sib nrug. Ntev npaum li qhov loj ntawm tus ncej hlau nplaum yog tsau, qhov loj ntawm lub thawv xuab zeb tseem raug kho. Nws yog yuav luag tsis yooj yim sua kom nrum ib tug casting uas tshaj qhov luaj li cas ntawm cov xuab zeb lub thawv, uas yog feem ntau tsuas yog haum rau pouring me me pieces ntawm ib puas thiab kaum kilograms. Tsis zoo siab cov khoom indium casting yog ntau ntxiv rau qhov loj ntawm castings. Cov thawv xuab zeb ntawm ntau qhov sib txawv tuaj yeem muab tso rau ntawm tib lub rooj vibration, yog li castings ntawm ntau qhov ntau thiab tsawg tuaj yeem tsim tau yooj yim heev.
Txawm li cas los xij, vim qhov tsis tshua muaj zog ntawm cov qauv yas ua npuas ncauj thiab qhov tseeb tias cov khoom ntim tsis tuaj yeem tsis sib xws thaum lub sijhawm ua haujlwm, cov qauv yooj yim deformed, uas coj qee qhov teeb meem rau casting loj, nqaim thiab nyias. Yog li ntawd, xav txog qhov yooj yim ntawm kev lag luam thiab cov txheej txheem thev naus laus zis uas twb muaj lawm, nws raug nquahu kom cam khwb cia nrog qhov tsis zoo siab compact casting tsawg dua 2t (tshwj xeeb tshaj yog 500kg) thiab phab ntsa thickness ntau dua 4 hli.
Qhov ncaj qha ua rau pwm ua los ntawm Jianzhi malleable steel yog tias lub zog ntawm cov xuab zeb moulding tsawg dhau, uas yog, lub zog adhesion ntawm cov xuab zeb nplej yog tsawg dua li qhov adhesion quab yuam ntawm cov xuab zeb nplej ntawm tus qauv. Cov laj thawj tshwj xeeb yog raws li hauv qab no:
1. Casting thiab qauv tsim
(1) Vim yog tsim tsis tsim nyog, lub kaum sab xis ntawm lub kaum sab xis tsis txaus. Yog hais tias lub kaum sab xis ntawm cov qauv me me dhau lawm, nws yuav tsim cov nyhuv adsorption, uas yuav ua rau kom muaj kev sib txhuam quab yuam thiab ua rau xoob ntawm qhov chaw ntawm cov xuab zeb molding.
(2) Kev tsim qauv casting muaj qhov sib sib zog nqus thiab nqaim. Cov xuab zeb dai nyob rau hauv qhov concave no yog ib qho yooj yim rau tawg thaum lub pwm yog lifted. Hauv qhov no, siv cov xuab zeb hooks thiab xuab zeb-kho ntoo chips kom ntxiv dag zog rau cov xuab zeb hauv qhov no.
2. Kev tshwm sim
(1) Qhov saum npoo ntawm tus qauv tsis du lossis cov txheej yog ntxhib. Qhov no tuaj yeem ua rau cov xuab zeb sib txuas rau saum npoo ntawm cov qauv hauv cov qauv tawg los yog clumped. Thaum xuab zeb, vim tias qhov saum npoo ntawm cov qauv yog ntxhib, cov xuab zeb molding yuav raug pounded rau hauv kev nyuaj siab ntawm cov qauv, thiab qhov no ntawm cov xuab zeb yuav loosen los yog poob tawm thaum pwm tshem tawm.
(2) Cov txheej txheem siv rau cov qauv yog tsis tsim nyog, thiab nws yooj yim rau kev ua raws li cov xuab zeb nplej.
(3) Muaj pits los yog looseness ntawm qhov chaw seem. Nyob rau hauv txoj kev no, thaum cov pwm raug tshem tawm, cov xuab zeb molding sticks rau tus qauv.
3. Lub thawv xuab zeb thiab nws qhov kev npaj
(1) Lub rigidity ntawm lub thawv xuab zeb yog qhov tsis zoo. Thaum lub sij hawm extrusion molding, rigidity ntawm lub thawv xuab zeb yog qhov tsis zoo, uas yuav ua rau lub thawv xuab zeb rov qab los yog deform. Thaum lub siab tso tawm, yog tias lub thawv xuab zeb rebounds, nws yuav nyem qhov concave ntawm cov xuab zeb pwm. Cov xuab zeb molding yuav lo rau cov qauv, yog li tsim succulents.
(2) Qhov siab ntawm lub thawv xuab zeb tsis txaus. Vim tias qhov siab ntawm lub thawv xuab zeb tsis txaus, cov xuab zeb dai yuav nruj heev, yog li qhov kev sib txhuam quab yuam loj heev thaum lub pwm qhib, ua rau cov xuab zeb xoob xoob.
(3) Yog tias muaj ntau cov qauv tso rau hauv ib lub thawv xuab zeb ntawm ib qho loj, nws yooj yim ua rau cov xuab zeb tsis sib xws thiab tsis sib xws, yog li ua rau cov xuab zeb molding nkig.
(4) Kev co ntau dhau ntawm tus qauv ua rau cov xuab zeb dai kom tawg nyob rau hauv qhov kev txiav txim ntawm shear quab yuam.
