Koj pom ntau cov lus hais txog cov shafts ncaj nraim hauv cov xaim thiab kev ua haujlwm bar, tab sis cov dab neeg tiag tiag tsis nyob hauv cov catalog specs. Nws yog nyob rau hauv grime, lub tshav kub mus, thiab hloov maj mam deflection koj tsuas pom tom qab khiav 50 tons ntawm high-carbon steel. Txhua tus neeg tsom mus rau qhov nyuaj, tab sis yog tias cov tub ntxhais tsis raug, nws tsuas yog ib qho zoo nkauj, kim stick tos kom ua rau txoj kab kaw.
Lub hauv paus misconception: Hardness tsis yog txhua yam
Thaum lub khw feem ntau lossis txawm tias qee qhov OEMs spec a straightener ncej, thawj cov ntaub ntawv taw tes yog ib txwm nto hardness. HRC 58, 60, tej zaum siab dua. Tseeb, koj xav tau qhov hnav tsis kam qhov twg cov yob sib cuag. Tab sis kuv tau rub sib nrug shafts uas tau ntsib cov hardness spec tseem ua tsis tau ntxov ntxov. Qhov tsis ua haujlwm tsis nyob ntawm qhov chaw; nws yog ib qho qaug zog tawg pib txog 5mm hauv qab no. Cov khoom tseem ceeb muaj qhov tsis zoo toughness. Nyob rau hauv lub cyclic bending loads ntawm straightening, tshwj xeeb tshaj yog nrog inconsistent feedstock, uas yog qhov uas nws muab.
Qhov no yog qhov kev xaiv cov khoom siv tiag tiag. Nws tsis yog tsuas yog stainless hlau lossis hlau alloy. Rau ib tug ncej uas pom muaj siab dynamic kev nyuaj siab, koj xav tau ib tug los ntawm-hardening qib nrog ib tug zoo tshuav nyiaj li cas. Ib yam dab tsi zoo li 4140 lossis 4340, raug kho kom sov kom tau txais cov qauv martensitic zoo ib yam los ntawm ntu ntu. Kuv twb pom outfits sim txuag nqi nrog ib tug nruab nrab carbon steel thiab cia li induction harden nto. Nws ua haujlwm, kom txog rau thaum nws tsis ua - thiab kev so yog kev puas tsuaj, tsis maj mam.
Peb muaj rooj plaub nrog cov neeg siv khoom siv cov kab hluav taws xob siab ceev rau lub caij nplooj ntoos hlav steel. Lawv tau noj los ntawm shafts txhua 8 lub hlis. Cov specs saib zoo ntawm daim ntawv. Peb tau txais ib qho ntawm lawv cov chav ua tsis tau zoo, tau ua qhov kev tshuaj ntsuam metallurgical, thiab pom qhov sib txawv tseem ceeb hauv cov txheej txheem microstructure - cov cim qhia ntawm qhov tsis raug quenching. Qhov saum npoo yog tawv, tab sis lub hauv paus tseem ceeb yog qhov sib txawv, cov khoom tsis muaj zog. Kev kho tsis yog ib qho khoom siv nyuaj, tab sis cov txheej txheem tswj tau ntau dua. Qhov no yog hom nuance tuam txhab uas muag nyiam Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) nkag siab los ntawm lawv lub xyoo caum hauv casting thiab machining. Lawv tsis yog txiav hlau xwb; lawv tab tom tswj hwm tag nrho cov khoom hloov pauv, uas yog qhov tseem ceeb rau kev ntxhov siab zoo li no.
Geometry & Tolerances: Qhov Kev Xav Tau Raws Li Lub Tshuab
Daim duab hu rau ib tug ncaj kam rau ua ntawm, hais, 0.05mm ib 'meter'. Achievable ntawm ib tug zoo kws dhos los yog grinder. Tab sis qhov ntawd yog nyob rau hauv chav kuaj xyuas huab cua. Qhov kev sim tiag tiag yog thaum lub ncej yog bolted rau hauv lub thav duab straightener, pre-loaded, thiab rhuab mus rau 60 ° C los ntawm kev sib txhuam thiab ambient cog cua sov. Nws puas nyob ncaj? Los yog nws yuav siv sij hawm me ntsis?
Txoj kab uas hla tolerances rau cov kabmob cov phau ntawv journal yog lwm yam classic pitfall. nruj heev ib tug haum, thiab koj muaj feem yuav galling thaum lub sij hawm installation los yog qaug dab peg los ntawm thermal expansion. Tsis dhau xoob, thiab koj tau fretting hnav, kev co, thiab thaum kawg, wobble uas rhuav tshem qhov tseeb ntawm qhov ncaj. Kuv nyiam qhov kev hloov pauv, qee zaum txawm hais tias me ntsis lead-hauv chamfer uas tsis yog ib txwm nyob ntawm tus qauv luam tawm, ua kom thaj chaw kho tau yam tsis muaj hydraulic xovxwm thiab thov Vajtswv.
Tom qab ntawd muaj qhov tiav. Cov ntawv xov xwm xav tau kev sib tsoo zoo, feem ntau mus rau 0.4 Ra lossis zoo dua. Tab sis cov seem ntawm cov rooj zaum yob? Tej zaum koj yuav pom machined grooves los yog ib tug ntxhib-tig tiav. Muaj ib qho laj thawj. Qhov kev ntxhib los mos no tuaj yeem pab khaws cov roj nplua nyeem thiab ua kom cov cua sov zoo dua li lub ntsej muag zoo kawg nkaus. Nws yog ib qho me me, cov ntsiab lus uas koj kawm tau los ntawm kev pom cov khoom no hauv kev pabcuam, tsis yog los ntawm kev tsim lawv.
Kev Tsim Nyog Dance: Casting vs. Machining los ntawm Bar
Rau cov qauv loj, a straightener ncej feem ntau machined los ntawm forged los yog dov bar Tshuag. Nws yog kwv yees. Tab sis rau cov kab uas loj dua, cov yam ntxwv tsis sib xws (xws li flanges lossis cov duab sib txawv txawv), lossis thaum cov khoom siv tawm los yog tus nqi loj, casting ua nthuav. Qhov no yog qhov uas tus foundry qhov kev txawj ntse yog qhov tseem ceeb.
Lub cam khwb cia hlau xav tau cov txheej txheem flawless kom tsis txhob muaj cov kab noj hniav hauv cov kab noj hniav los yog cov kev sib txuas uas ua rau muaj kev ntxhov siab. Qhov zoo dua yog koj tuaj yeem tau los ze zog rau cov duab zoo, txuag ntau lub sijhawm ua haujlwm ntawm cov khoom pov tseg. Qhov downside yog koj kiag li yuav tsum muaj kev sim tsis muaj kev puas tsuaj (NDT). Peb tau ua qhov kev sim khiav ntau xyoo dhau los ntawm txoj kab uas hla loj rau txoj kab tooj liab. Peb mus nrog ib tug casting los integrate cov kabmob vaj tse. Thawj tsab xov xwm dhau tag nrho cov kev ntsuam xyuas qhov ntev tab sis ua tsis tiav qhov kev sim ultrasonic - ib qho me me, pawg porosity cheeb tsam txoj cai nyob rau hauv ib cheeb tsam siab. Yuav tsum khawb nws. Qhov kev sim thib ob, nrog kev hloov kho rooj vag thiab riser tsim los ntawm qhov chaw tsim khoom, tau ruaj khov.
Qhov no yog hom kev muaj peev xwm uas koj tab tom nrhiav hauv tus neeg muag khoom. Ib lub tuam txhab zoo li QSY, nrog nws cov keeb kwm ntev hauv plhaub molding thiab peev casting, tuaj yeem xaiv cov kev xaiv no. Plhaub pwm yog qhov zoo rau cov hlau thiab hlau qhov chaw nrog qhov zoo ntawm qhov tiav thiab qhov tseeb qhov tseeb, thaum peev casting yog rau ntau qhov nyuaj, alloy-hnyav tsim. Lawv tuaj yeem txheeb xyuas seb lub ncej puas zoo dua los ntawm cov khoom siv ntawm lawv CNC machining cov chaw lossis yog tias txoj kev casting yog qhov ua tau zoo dua, thiab lawv muaj kev paub txog metallurgical los qhia txog txoj cai Nickel-raws li alloys los yog cobalt-based alloys rau qhov hnyav hnyav lossis corrosion ib puag ncig.
Hom Kev Ua Tsis Taus: Cov Dab Neeg Shafts Qhia
Koj kawm ntau dua los ntawm qhov tawg dua li qhov zoo meej. Lub pob txha tawg yog ib phau ntawv keeb kwm. Ib qho kev huv, ib lub dav hlau tawg nrog cov cim puam tawg ntawm ib qho taw tes? Classic qaug zog tsis ua hauj lwm. Pib ntawm qhov kev ntxhov siab-tej zaum lub kaum ntse ntse ntawm qhov kawg ntawm txoj hauv kev tseem ceeb uas tsis yog hluav taws xob zoo, lossis cov cuab yeej cim uas ua zoo li micro-crack.
Kuv nco qab ib tug ncej uas khaws cia tus yuam sij Woodruff. Txhua tus tau txhim kho cov khoom tseem ceeb. Thaum kawg, peb saib ntawm qhov tseem ceeb ntawm nws tus kheej. Nws tau machined nrog tus qauv kawg zeb, tawm hauv ib qho ntse, square hauv qab. Qhov tawg tau pib muaj. Txoj kev daws teeb meem yog ib qho kev qhia yooj yooj yim rau tus kws kho tshuab: Muab lub vojvoog rau hauv qhov tseem ceeb hauv qab, loj npaum li tus qauv tso cai. Tsis muaj lwm yam ua tsis tiav. Nws yog tsib feeb machining nthuav dav uas feem ntau CAD qauv tsis txawm qhia.
Lwm qhov kev ua tsis zoo, tsis meej pem yog torsional cua-up. Nyob rau hauv straighteners nrog tsav rolls, lub ncej xa torque. Yog hais tias txoj kab uas hla yog under-tsim rau lub torsional load, koj tau angular deflection. Qhov no tsis tawg lub ncej tam sim ntawd; nws tsuas yog ua rau cov qauv straightening inconsistent thiab ruins cov khoom zoo. Tej zaum koj yuav caum qhov teeb meem rau lub lis piam, kho cov yob siab, ua ntej koj xav xyuas seb tus ncej nws tus kheej yog qhov sib tw hauv qab load.
Kev sib koom ua ke & Kev xav ntawm tus ncej zoo
Thaum kawg, a straightener ncej tsis yog kob. Nws yog ib feem ntawm lub kaw lus nrog bearings, vaj tse, yob, thiab lub tshuab ncej. Qhov zoo tshaj plaws ncej tuaj yeem cia los ntawm kev ua haujlwm tsis zoo thaum lub sijhawm teeb tsa. Peb ib txwm hais txog cov txheej txheem kev teeb tsa: siv cov lasers sib dhos, tsis yog qib siab. Txheeb xyuas qhov kev sib tw ntawm ntau lub ntsiab lus raws li tus ncej ntev thaum nws zaum hauv nws cov bearings, tsis yog ntawm lub rooj ntev zaum.
Kuj tseem muaj qhov yuav luag tsis muaj kev xav rau lub ntsej muag zoo. Qhov nyiaj tshuav. Thaum koj tig nws ntawm qhov chaw ruaj khov ua ntej kev teeb tsa, nws yuav tsum tig ncaj nraim tsis muaj qhov hnyav. Qhov saum npoo yuav tsum huv si, tsis muaj cuab yeej ua pov thawj kab uas koj tuaj yeem ntes tus ntiv tes rau. Qhov hnyav yuav tsum xav tias tsim nyog rau nws qhov loj thiab cov khoom siv - ib qho cim ntawm qhov sib xws, tshwj xeeb tshaj yog nyob rau hauv cov qauv cam khwb cia.
Cov neeg muab khoom uas tau txais qhov no yog cov uas tau nyob hauv lub Hoobkas hauv pem teb lawv tus kheej. Lawv paub tias lawv feem yuav tsum ua haujlwm hauv qhov chaw qias neeg, vibrating, kub. Nws tsis yog ib daim duab rau lawv xwb. Thaum koj ua haujlwm nrog tus khub uas muaj ob qho kev tshaj lij casting rau cov khoom siv ncaj ncees thiab qhov tseeb CNC machining rau qhov kawg haum thiab kev ua haujlwm - zoo li cov kev pabcuam sib koom ua ke koj yuav pom ntawm lub tuam txhab nrog QSY's profile - koj tsis yog yuav ib qho khoom siv xwb. Koj tab tom yuav ib chunk ntawm kev ntseeg. Qhov ntawd yog qhov ua kom txoj kab ua haujlwm khiav, ua haujlwm tom qab ua haujlwm. Lub hom phiaj yog kom cov ncej yog qhov kawg uas cov neeg saib xyuas puas tau xav txog.
