Nyob rau hauv high-precision manufacturing thiab metrology, granite mechanical Cheebtsam - xws li precision beams, gantry thav duab, thiab nto daim hlau - yog indispensable rau lawv inherent stability. Crafted los ntawm ib txwm muaj hnub nyoog pob zeb, cov khoom siv no ua tus qauv kub rau kev tshuaj xyuas qhov flatness thiab qhov tseeb ntawm qhov tseem ceeb ntawm cov khoom siv kho tshuab. Txawm li cas los xij, txawm tias granite, thaum raug mob hnyav lossis siv tsis raug, tuaj yeem pom qhov deformation ntawm nws lub neej ua haujlwm ntev.
Nkag siab txog cov txheej txheem ntawm cov deformations no yog qhov tseem ceeb rau kev txo cov kev pheej hmoo thiab txuas ntxiv lub neej ntawm koj cov peev txheej. Ntawm ZHONGHUI Group (ZHHIMG®), peb ua raws li kev tswj hwm nruj kom tiv thaiv kev tsim khoom tsis xws li cov xuab zeb qhov, khawb, lossis kev suav nrog, tab sis qhov kawg ntawm cov neeg siv ib puag ncig qhia txog lub zog uas yuav tsum tau tswj.
Lub Physics ntawm Granite Deformation
Thaum granite yog tshwj xeeb nruj thiab tiv taus thermal expansion, nws tsis yog impervious rau mechanical stress. Lub hom phiaj tseem ceeb ntawm deformation pom nyob rau hauv tej yam khoom siv, nrog rau granite, sib haum mus rau lub zog tshwj xeeb thov:
- Shear Stress: Hom deformation no tshwm sim raws li qhov sib txawv ntawm qhov sib txawv ntawm cov khoom. Nws tshwm sim thaum ob lub zog sib npaug thiab sib luag ua raws cov kab sib txuas ntawm kev ua, ua rau cov ntu ntawm cov khoom siv granite hloov mus rau ib leeg.
- Tension thiab Compression: Qhov no yog qhov yooj yim tshaj plaws daim ntawv, uas ua rau ob qho tib si elongation (nruj) los yog shortening (compression) ntawm cov khoom ntev. Nws yog feem ntau tshwm sim los ntawm ib tug ncaj khub ntawm sib npaug zos thiab opposite rog ua raws li cov tivthaiv lub axial centerline, xws li tsis zoo torqued mounting bolts.
- Torsion: Torsional deformation yog qhov sib tw ntawm cov khoom nyob ib ncig ntawm nws tus kheej axis. Qhov kev sib tw twisting no yog ntxias los ntawm kev tawm tsam cov khub niam txiv (cov khub ntawm lub zog) uas nws lub dav hlau ntawm qhov kev txiav txim yog perpendicular mus rau lub axis, feem ntau pom yog hais tias ib tug hnyav load yog eccentrically thov los yog yog hais tias tus tivthaiv lub mounting puag yog unevenly.
- Bending: Khoov ua rau cov khoom ncaj nraim rau nkhaus. Qhov no feem ntau yog tsim los ntawm ib qho kev sib hloov ntawm lub zog ua haujlwm perpendicular mus rau lub axis los yog los ntawm ib khub ntawm cov khub niam txiv uas tsis sib haum xeeb thov nyob rau hauv lub dav hlau longitudinal. Nyob rau hauv ib tug granite gantry thav duab, piv txwv li, tsis sib npaug ntawm kev thauj khoom lossis kev txhawb nqa tsis txaus tuaj yeem ua rau muaj kev puas tsuaj rau kev ntxhov siab.
Cov kev coj ua zoo tshaj plaws: Khaws qhov tseeb nrog kev ncaj ncaj
Granite Cheebtsam feem ntau tso siab rau cov cuab yeej siv pabcuam xws li granite straightedges los ntsuas cov kab sib txawv, sib npaug, thiab flatness hla ntu luv. Siv cov cuab yeej precision no kom raug yog tsis sib tham rau kev khaws cia ob qho tib si granite siv thiab cov cuab yeej nws tus kheej.
Ib kauj ruam hauv paus yog ib txwm txheeb xyuas qhov tseeb qhov tseeb ua ntej siv. Qhov thib ob, qhov sib npaug ntawm qhov kub thiab txias yog qhov tseem ceeb: tsis txhob siv qhov ncaj los ntsuas cov khoom ua haujlwm uas kub dhau los yog txias dhau, vim qhov no qhia txog kev ua yuam kev thermal rau hauv kev ntsuas thiab pheej hmoo deformation ib ntus ntawm cov cuab yeej granite.
Qhov tseem ceeb tshaj plaws, lub straightedge yuav tsum tsis txhob rub rov qab thiab tawm mus thoob plaws workpiece nto. Tom qab ua tiav ib qho kev ntsuas, nqa lub straightedge tag nrho ua ntej tsiv mus rau txoj hauj lwm tom ntej. Txoj cai yooj yim no txwv tsis pub hnav tsis tsim nyog thiab khaws cia qhov chaw ua haujlwm tseem ceeb ntawm ob qho tib si ncaj thiab cov khoom raug tshuaj xyuas. Tsis tas li ntawd, xyuas kom lub tshuab muaj kev nyab xeeb tawm - ntsuas qhov txav mus los yog txwv tsis pub vim nws ua rau muaj kev puas tsuaj sai sai thiab muaj kev nyab xeeb. Thaum kawg, ob qho tib si ncaj nraim thiab qhov chaw soj ntsuam yuav tsum tau ua kom huv si thiab tsis muaj burrs lossis chips, vim tias txawm tias cov kab mob microscopic tuaj yeem qhia qhov ntsuas qhov tsis raug.
Lub luag haujlwm ntawm kev huv huv hauv cov qauv kev ntseeg siab
Tshaj li qhov yooj yim tshem tawm, kev ua kom huv hauv kev lag luam yog ib qho tseem ceeb rau kev tiv thaiv cov teeb meem hauv cov khoom siv tshuab hnyav. Ua ntej sib dhos lossis kev pabcuam ntawm ib lub tshuab so ntawm lub hauv paus granite, kev tu kom huv yog yuav tsum tau ua. residual casting xuab zeb, xeb, los yog hlau chips yuav tsum tau muab tshem tawm tag nrho, feem ntau yuav tsum tau siv cov tshuaj ntxuav xws li diesel, kerosene, los yog cov kuab tshuaj tshwj xeeb, tom qab ziab nrog cua compressed. Rau cov kab noj hniav sab hauv ntawm kev txhawb nqa cov qauv hlau (xws li cov uas txuas nrog cov granite), siv cov txheej tiv thaiv xeb yog ib qho kev tiv thaiv tseem ceeb.
Thaum sib sau ua ke cov txheej txheem sib xyaw ua ke rau hauv granite, xws li tsav tsheb ciav hlau lossis cov ntsia hlau ntsia hlau, cov ncauj lus kom ntxaws kev huv thiab kev kuaj xyuas kev sib raug zoo yog qhov tseem ceeb. Cov Cheebtsam yuav tsum tsis muaj cov xim pleev xim ua ntej sib sau ua ke, thiab qhov tseem ceeb ntawm mating nto yuav tsum tau lubricated los tiv thaiv kev sib txhuam thiab hnav. Hauv txhua qhov kev ua haujlwm sib dhos, tshwj xeeb tshaj yog thaum ntsaws ntsaws ruaj ruaj lossis haum cov kabmob, tsis txhob siv lub zog ntau dhau lossis tsis sib xws. Kev sib raug zoo, kev tshem tawm kom raug, thiab kev siv dag zog zoo ib yam yog cov yuam sij kom ntseeg tau tias cov khoom siv tshuab ua haujlwm tau zoo thiab tsis hloov pauv kev puas tsuaj, asymmetrical stresses rov qab rau hauv ultra-stable ZHHIMG® granite foundation.
