Honing raj, raws li siab -cov tubing precision, yog dav siv nyob rau hauv hydraulic systems, automotive manufacturing, aerospace, thiab lwm yam teb. Qhov zoo ntawm lawv cov kev ua haujlwm ncaj qha cuam tshuam rau kev ua haujlwm thiab kev ua neej nyob ntawm cov cuab yeej siv, ua rau nws tseem ceeb heev rau kev paub txog kev tshawb fawb honing thiab cov ntsiab lus tseem ceeb. Kab lus no piav qhia txog kev siv thev naus laus zis, cov kauj ruam tseem ceeb, thiab kev tswj xyuas zoo rau honing raj.
I. Cov Ntsiab Cai ntawm Honing Tubes
Honing yog cov txheej txheem kev ua tiav tiav nyob rau hauv uas lub pob zeb (sib tsoo bar) ntawm lub taub hau honing siv lub siab rau sab hauv phab ntsa ntawm lub raj los ntawm kev sib xyaw ua ke ntawm kev sib hloov thiab rov ua haujlwm, ua tiav kev sib tsoo thiab polishing ntawm phab ntsa ntawm lub raj. Lub hom phiaj ntawm honing raj muaj xws li kev txhim kho qhov tseeb qhov tseeb, txo qhov roughness ntawm qhov chaw, kho qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ncaj, thiab ua ib qho kev sib xws, ntoo khaub lig- qauv roj zaj duab xis los txhim kho qhov hnav tsis kam thiab lubrication ntawm lub raj.
II. Cov txheej txheem tseem ceeb rau Honing Tubes
1. Txheej txheem Honing
Ib txwm honing siv lub tshuab honing ruaj. Lub taub hau honing yog tsav los ntawm lub tshuab spindle, rotating thaum ib txhij reciprocating raws lub raj axis. Thaum lub sij hawm tus txheej txheem, lub honing pob zeb yog hydraulically los yog mechanically nias tiv thaiv lub raj lub puab phab ntsa, maj mam tshem tawm cov khoom ntau dhau thiab ua tiav lub hom phiaj dimension. Txoj kev no tsim nyog rau kev tsim khoom loj thiab muaj kev ua haujlwm siab, tab sis yuav tsum muaj kev paub ntau ntawm cov neeg siv khoom.
2. CNC Honing Technology
Nrog rau kev nce qib ntawm automation technology, CNC honing tshuab tau nrov zuj zus. Cov thev naus laus zis no siv cov kev pab cuam -tswj honing lub taub hau ceev, pub tus nqi, thiab reciprocating stroke, ua kom muaj kev hloov pauv ntawm kev ua haujlwm kom haum rau cov raj ntawm cov khoom sib txawv thiab cov lus qhia tshwj xeeb. CNC honing muaj ntau dua repeatability thiab sib xws, ua rau nws tshwj xeeb tshaj yog haum rau siab - kawg manufacturing daim ntaub ntawv xws li siab -precision hydraulic thooj voos kheej kheej thiab precision steel kav. 3. Ua ke Honing thiab Polishing
Qee cov ntawv thov (xws li ultra-cov khoom siv hydraulic precision) yuav tsum muaj txheej txheem polishing tom qab honing kom txo qhov roughness ntawm qhov chaw (rau Ra hauv qab 0.1μm). Cov txheej txheem ua ke no feem ntau siv cov mos abrasives lossis tshwj xeeb coated oilstones los xyuas kom meej siab thaum tuav cov khoom zawv zawg zoo heev ntawm lub raj nplaim.
III. Cov ntsiab lus tseem ceeb rau Tube Honing
1. Abrasive thiab Oilstone xaiv
Lub grit loj, hardness, thiab daim ntawv cog lus hom ntawm honing oilstone ncaj qha cuam tshuam rau machining tau. Ib coarser grit (piv txwv li, 80-120 mesh) feem ntau yog siv rau ntxhib honing kom sai tshem tawm cov khoom ntau dhau, thaum lub grit zoo dua (xws li, 240-400 mesh) yog siv rau qhov zoo honing kom ua tiav qhov siab. Tsis tas li ntawd, lub oilstone hardness yuav tsum tau kho raws li cov khoom siv raj (xws li, carbon steel, stainless hlau, los yog alloy) kom tsis txhob hnav ntau dhau los yog khawb . 2. Optimizing Processing Parameters
Cov tsis tseem ceeb hauv cov txheej txheem honing muaj xws li:
• Kev sib hloov ceev: cuam tshuam rau kev ua haujlwm ntawm kev txiav thiab kev ntxhib los mos, feem ntau tswj tsis pub dhau 20-100 rpm ntau;
•Reciprocating ceev: txiav txim siab qhov ceev ntawm crosshatch qauv, feem ntau teem ntawm 10-30 m / min;
•Feed siab: yuav tsum muaj qhov sib npaug ntawm machining efficiency thiab nto zoo. Kev siab dhau heev tuaj yeem ua rau lub raj phab ntsa deformation.
3. Cua txias thiab lubrication
Cov txheej txheem honing tsim cov cua kub tseem ceeb, yuav tsum tau siv cov roj tshwj xeeb honing los yog emulsion kom txias thiab lubrication kom txo qis thermal deformation thiab yaug tawm chips. Coolant huv huv kuj ncaj qha cuam tshuam cov txheej txheem stability. Kev pom zoo pom zoo kom tiv thaiv kev kis kab mob thib ob ntawm lub raj phab ntsa los ntawm impurities.
IV. Kev Tswjhwm Zoo ntawm Honed Tubes
Txhawm rau kom ntseeg tau tias cov raj honed ua tau raws li cov qauv kev qhia, kev sim nruj yuav tsum tau ua hauv cov hauv qab no:
1. Dimensional Accuracy: Siv lub micrometer sab hauv lossis kev sib koom tes ntsuas lub tshuab los xyuas lub raj txoj kab uas hla (feem ntau nyob rau hauv ± 0.01mm);
2. Nto Roughness: Ntsuas tus nqi Ra siv lub roughness tester. Rau honed hlab rau hydraulic daim ntaub ntawv, Ra Tsawg dua los yog sib npaug rau 0.4μm feem ntau yuav tsum tau;
3. Geometric Accuracy: Tshawb xyuas roundness, straightness, thiab cylindricity los xyuas kom meej haum haum ntawm lub raj thiab mating Cheebtsam.
V. Xaus
Honding tubes yog cov cuab yeej tsim khoom precision uas sib txuas cov tshuab, cov khoom siv, thiab cov txheej txheem. Los ntawm kev xaiv qhov tsim nyog honing txoj kev, optimizing kev ua tsis tau, thiab ntxiv dag zog rau kev tswj kom zoo, kev ua tau zoo thiab kev cia siab ntawm lub raj tuaj yeem txhim kho tau zoo. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib ntawm kev txawj ntse manufacturing thiab ultra- precision machining technologies, cov txheej txheem honing yuav ntxiv mus rau kev ua tau zoo dua thiab txawj ntse, muab siab dua - raj zoo daws rau siab - khoom siv kawg.
