Yuav Ua Li Cas Pwm Cement Block
Tsib -Tsev Phau Ntawv Qhia rau Kev Tsim Kho Ib Yam
Cement block molding yog txheej txheem ntawm kev tsim cov cement- xuab zeb- sib xyaw ua ke rau hauv cov blocks tiav siv cov pwm precision hauv kev tswj kev vibration thiab siab. UNIK tau tsim cov tshuab cib thiab pwm txij li xyoo 2008, nrog ntau tshaj 15 xyoo ntawm kev xa tawm mus rau 28 lub teb chaws. Phau ntawv qhia no qhia txog tsib kauj ruam tseem ceeb rau kev tsim cov qib siab - cement blocks zoo.
1. Npaj cov pwm thiab tshuab
Ua ntej cov cement nkag mus rau hauv pwm, cov cuab yeej yuav tsum tau npaj.
Tshawb xyuas cov pwm- Tshawb xyuas cov kab noj hniav kom pom cov kab nrib pleb, hnav, lossis cov pob zeb seem ntawm kev khiav dhau los. Ua tib zoo saib xyuas rau cov ces kaum thiab cov tub ntxhais qhov chaw, vim tias cov no feem ntau ua rau kev puas tsuaj.
Ntxuav kom huv si- Siv cov cua compressed thiab txhuam txhuam kom tshem tag nrho cov khib nyiab. Tsis txhob siv cov cuab yeej hlau hauv cov kab noj hniav; khawb yuav ua rau cov blocks lo thiab txo qhov zoo ntawm qhov chaw.
Thov tso tus neeg sawv cev- Txheej tag nrho cov kab noj hniav nrog ib txheej nyias nyias ntawm pwm tso roj. Cov kauj ruam no yog qhov tseem ceeb rau kev tshem tawm kom huv thiab txuas ntxiv lub neej pwm.
Mount lub pwm- Khaws cov pwm rau lub tshuab thaiv lub rooj vibration. Tighten bolts nyob rau hauv ib tug ntoo khaub lig qauv kom paub meej tias compression. Xyuas kom meej tias cov pwm yog qib siv lub ntsuas qhov tseeb.
Tshawb xyuas lub tshuab teeb tsa- Paub meej tias qhov kev vibration zaus, compression siab, thiab lub voj voog lub sij hawm sib tw nrog cov lus qhia tshwj xeeb rau koj hom thaiv.
UNIK pwm yog tsim los ntawm Cr12MoV lossis 9CrSi alloy cov cuab yeej hlau nrog kev kho cua sov carburizing, ua tiav qhov tawv tawv ntawm HRC59-62 thiab qhov ntev ntev ntawm ± 0.3 hli.
2. Sib tov cov cement kom raug
Qhov zoo ntawm cov block tiav yog nyob ntawm qhov sib xyaw tsim.
Standard cement block mix ratio- Ib qho piv txwv yog ib feem ntawm cov cement, ob seem xuab zeb, thiab plaub qhov sib sau ua ke los ntawm ntim. Kho raws li koj qhov kev xav tau lub zog tshwj xeeb.
Cov ntsiab lus dej- Ntxiv dej maj mam kom txog thaum cov khoom sib tov tuav nws cov duab thaum nyem tab sis tsis muaj cov seem ntub dej ntawm koj txhais tes. Lub hom phiaj poob ntawm 60-80mm rau tshuab moulding.
Sib tov sib xws- Cov sib tov yuav tsum damp txaus kom ntws hauv qab vibration tab sis qhuav txaus los tuav cov duab tom qab ejection. Tshaj - ntub dej ua rau cov blocks poob; tshaj -qhuav mix tsim voids thiab tsis muaj npoo.
Lub sijhawm sib tov– Sib tov rau 3-5 feeb tom qab tag nrho cov khoom xyaw ntxiv. Kev sib xyaw tsis txaus ua rau lub zog tsis sib xws; over-mixing tuaj yeem rhuav tshem cov khoom sib xyaw.
Kev sim- Ua ntej tag nrho cov khoom, khiav ib pawg me me thiab sim thaiv lub zog tom qab 7 thiab 28 hnub ntawm kev kho. Kho qhov sib piv raws li xav tau.
Rau kev sib cuam tshuam lossis cov khoom siv zoo nkauj, UNIK pom zoo kom siv cov khoom sib xyaw me me (tsawg dua lossis sib npaug li 10mm) thiab ntxiv 5-8% xuab zeb ntxiv txhawm rau txhim kho ntws mus rau hauv cov kab noj hniav kom ntxaws.
3. Khiav lub voj voog Moulding
Lub voj voog molding muaj plaub theem: filling, vibration, compression, thiab ejection.
Sau- Muab cov cement sib tov sib npaug rau txhua qhov kab noj hniav. Uneven filling tsim cov blocks nrog qhov hnyav thiab qhov hnyav. Rau ntau-kab kab noj hniav pwm, siv lub tshuab feeder rau kev faib khoom sib xws.
Kev vibration- Ua kom lub zog vibration. Feem ntau zaus rau cov cement blocks yog 3,500-4,500 RPM. Kev vibration ua rau cov khoom sib tov ntws mus rau hauv txhua qhov chaw hauv kab noj hniav, tshem tawm cov cua nkag, thiab ua kom cov khoom sib txuas. Tsis txaus vibration tawm voids; Kev vibration ntau dhau tuaj yeem cais cov aggregates.
Compression- Lub taub hau xovxwm siv lub siab downward. Siv 15-20% siab dua rau cov txheej txheem ntom ntom dua li cov khoom sib sib zog nqus. Tuav lub siab rau 1-2 vib nas this kom tso cai rau kev sib tov.
Tshem tawm- Lub taub hau xovxwm retracts, thiab lub stripper thawb cov tsim blocks tawm ntawm kab noj hniav. Ejection yuav tsum du thiab txawm. Jerky ejection qhia txog cov kab noj hniav ntxhib los yog lub kaum sab xis tsis txaus.
Lub sijhawm voj voog- Lub sijhawm lub voj voog zoo rau cov cement blocks yog 12-18 vib nas this, nyob ntawm qhov loj thiab lub peev xwm ntawm lub tshuab. Cov voj voog nrawm dua nce cov zis tab sis tuaj yeem txo qhov thaiv zoo.
UNIK's UNT series machines feature Siemens PLC tswj thiab Rexroth proportional hydraulics, kom ntseeg tau tias cov voj voog tsis sib xws thoob plaws ntau txhiab qhov rov ua dua.
4. Kho cov blocks kom raug
Freshly molded cement blocks tsis muaj zog thiab yuav tsum tau kho kom muaj zog.
Thawj stacking- Hloov cov blocks rau pallets lossis kho racks tam sim tom qab ejection. Ua tib zoo tuav; ntsuab blocks tuaj yeem tawg lossis deform nyob rau hauv siab.
Npog- Npog cov blocks nrog cov ntaub ntawv yas lossis cov ntaub ntub dej rau thawj 24-48 teev kom tiv thaiv kom tsis txhob ya raws. Cement xav tau dej rau cov tshuaj tiv thaiv hydration uas tsim kom muaj zog.
Lub sijhawm kho- Khaws cov thaiv kom ntub dej tsawg kawg 7 hnub rau cov qauv muaj zog, 14-28 hnub rau kev siv zog siab. Txau dej tsis tu ncua yog tias cov blocks tsis nyob rau hauv qhov chaw kaw kaw.
Kub- Qhov zoo tshaj plaws curing kub yog 20-30 degree. Hauv qab 10 degree, hydration slows ho. Hauv qab 5 degree, tiv thaiv cov blocks los ntawm khov, vim tias cov dej khov ua kom puas lub zog.
Txoj kev kho- UNIK muab chav kho cua sov thiab lub tsheb ntiv tes uas ua tiav lub zog tag nrho hauv 10 teev rau siab - ntim ntau lawm.
Cov blocks kho kom zoo ua tiav 65-75% ntawm lub zog kawg ntawm 7 hnub thiab 95-100% ntawm 28 hnub.
5. Tshawb xyuas thiab daws teeb meem
Kev tshuaj xyuas tsis tu ncua ua kom zoo ib yam thiab txheeb xyuas cov teeb meem ntxov.
Kev tshuaj xyuas qhov muag- Txheeb xyuas txhua qhov thaiv kom muaj kab nrib pleb, voids, ntug tsis sib luag, lossis cov blemishes saum npoo. Tsis lees txais ib qho thaiv uas tsis ua raws li koj tus qauv zoo.
Dimensional check- Ntsuas qhov ntev, qhov dav, qhov siab, thiab cov haujlwm tseem ceeb. Siv ib lub template los yog calipers. Kev kam rau siab yog feem ntau ± 1.5mm rau cov qauv thaiv, ± 1.0mm rau kev sib tshuam blocks.
Kev sim siab- Ib ntus tsoo cov qauv thaiv kom paub tseeb tias lub zog compressive ua tau raws li cov lus qhia tshwj xeeb. Standard hollow blocks feem ntau xav tau 5-10 MPa; khoom load-bearing blocks yuav xav tau 15-30 MPa.
Tej teeb meem thiab kev daws teeb meem:
| Teeb meem | Tej yam ua rau | Kev daws |
|---|---|---|
| Blocks lo rau hauv pwm | Rough kab noj hniav nto los yog tsawg cua ntsawj ntshab kaum | Pwm huv; polish kab noj hniav rau Ra 1.6; nce lub kaum sab xis mus rau 1.5-2.0 degree |
| Voids hauv blocks | Tsis txaus vibration lossis qhuav mix | Nce vibration zaus; ntxiv 2-5% dej |
| Kev tawg ntawm qhov chaw thaiv | Nthuav cov ces kaum nyob rau hauv pwm los yog thaum ntxov demolding | Ntxiv 3-5 hli vojvoog rau cov ces kaum; ncua sij hawm curing ua ntej tuav |
| Qhov siab tsis sib npaug | Pwm tsis qib los yog tsis sib xws bolt zawm | Re- theem pwm; nruj bolts nyob rau hauv cov qauv sib txawv |
| Tsis muaj zog blocks tom qab kho | Kev sib xyaw tsis raug lossis kev kho tsis txaus | Txheeb xyuas cov ntsiab lus ntawm cov cement; ncua lub sijhawm kho; tswj cov dej noo |
UNIK pwm feature radiused fab (3-5mm) thiab Ra 1.6 nto tiav raws li tus qauv, tshem tawm ob qho ntawm feem ntau cov ntsiab lus tsis ua haujlwm.
Vim li cas UNIK rau Cement Block Moulding
UNIK tau tsim cov tshuab cib thiab pwm txij li xyoo 2008, nrog ntau tshaj 15 xyoo ntawm kev xa tawm mus rau 28 lub teb chaws. Lub tuam txhab cov pwm yog sib xws nrog ntau tshaj 20 thoob ntiaj teb thaiv tshuab hom, suav nrog HESS, MASA, ZENITH, BESSER, TIGER, thiab Quadra.
Txhua UNIK pwm yog tsim los ntawm Cr12MoV lossis 9CrSi alloy cov cuab yeej hlau nrog kev kho cua sov, ua tiav qhov tawv tawv ntawm HRC59-62 thiab qhov ntev ntev ntawm ± 0.3mm. Kev cia siab lifespan yog 80,000-100,000 cycles nyob rau hauv tej yam kev mob.
UNIK tseem muaj cov tshuab ua kom tiav, suav nrog UNT series siab tsis siv neeg servo thaiv cov cav tov uas muaj Siemens PLC tswj, Rexroth proportional hydraulics, thiab ceev - hloov pwm tshuab.
