Honing yeeb nkab rau lub tog raj kheej
Honing kav rau hydraulic thooj voos kheej kheej sawv cev tshwj xeeb tubular cov khoom uas undergo precision internal machining kom ua tau raws li cov kev kam rau siab, superior nto finishes, thiab pom mechanical zog rau cov ntaub ntawv siv fais fab. Cov khoom siv no ua rau lub siab tseem ceeb- muaj cov thoob hauv hydraulic thiab pneumatic thooj voos kheej kheej uas qhov kev ncaj ncees ntawm qhov chaw thiab qhov tseeb qhov tseeb cuam tshuam ncaj qha rau kev ua haujlwm thiab kev pabcuam lub neej.

Honing kav rau hydraulic thooj voos kheej kheej sawv cev tshwj xeeb tubular cov khoom uas undergo precision internal machining kom ua tau raws li cov kev kam rau siab, superior nto finishes, thiab pom mechanical zog rau cov ntaub ntawv siv fais fab. Cov khoom siv no ua rau lub siab tseem ceeb- muaj cov thoob hauv hydraulic thiab pneumatic thooj voos kheej kheej uas qhov kev ncaj ncees ntawm qhov chaw thiab qhov tseeb qhov tseeb cuam tshuam ncaj qha rau kev ua haujlwm thiab kev pabcuam lub neej.
Tsim los ntawm ntau qib steel xws li E355 / ST52, C20, CK45, thiab hlau alloy, honing kav ua raws li cov qauv thoob ntiaj teb xws li DIN 2391, ASTM A519, thiab GB / T 3639. Cov tshuaj muaj pes tsawg leeg yog tswj hwm nruj heev -piv txwv li, E35% 2% 0. silicon, thiab 1.6% manganese nrog txwv phosphorus thiab sulfur (tsawg dua lossis sib npaug li 0.025%)-kom ntseeg tau zoo heev weldability, txhua yam muaj zog, thiab tiv taus qaug zog.
Cov txheej txheem tsim khoom suav nrog kev kos duab txias ua raws li kev ntxhov siab- txo kev kho cua sov (BK + S mob), uas txhim kho qhov ruaj khov thiab cov khoom siv kho tshuab. Qhov no ua rau muaj zog tensile xws li 520-640 MPa thiab tawm los ntawm 375-520 MPa nyob ntawm cov khoom siv qib. Kev ua haujlwm honing nws tus kheej siv cov pob zeb abrasive uas tshem tawm qhov tsis zoo ntawm qhov chaw microscopic thaum tsim cov yam ntxwv ntawm tus ntoo khaub lig-hatch nto qauv nrog tswj roughness ntawm Ra 0.1-0.8 μm. Cov qauv no ua kom yooj yim rau kev khaws cov roj nplua nyeem zoo, txo kev sib txhuam, thiab tiv thaiv cov dej bypass thaum lub tog raj kheej ua haujlwm.
Advanced manufacturing variants muaj xws li Skived thiab Roller Burnished (SRB) ua, uas ua ke precision txiav nrog siab -siab cov menyuam ua tiav kom tiav nto tiav zoo li Ra 0.1-0.4 μm. Cov kav dej no tuav nruj me ntsis kam rau ua nrog H8-H9 sab hauv txoj kab uas hla kev faib tawm, sab nraud ntawm 40-500 hli, phab ntsa thickness kam rau ua ntawm ± 5% mus rau ± 10%, thiab ncaj nraim hauv 0.5-1 hli ib 'meter'. Standard ntev ntev mus txog 12 meters, haum rau ob leeg ib leeg thiab ntau theem lub tog raj kheej tsim.
Cov precision no -engineered honing kav pom cov ntawv thov tseem ceeb hauv hydraulic thooj voos kheej kheej rau kev siv tshuab (excavators, bulldozers), cov cuab yeej siv (presses, txhaj tshuaj molding tshuab), cov khoom tuav cov tshuab (forklifts, cranes), thiab mobile hydraulic applications. Qhov saum npoo zoo tshaj plaws txo qis kev sib khi thiab lub nplhaib piston hnav, txo qis sab hauv, thiab txhim kho kev ua haujlwm tag nrho thaum ua haujlwm siab tshaj 350 bar.
Cov txheej txheem kev lees paub zoo suav nrog cov ntawv pov thawj cov khoom siv dav dav, kev txheeb xyuas qhov ntev, kev ntsuam xyuas qhov roughness ntawm qhov chaw, thiab kev ua haujlwm siab ua haujlwm tau zoo, ua kom ntseeg tau tias kev ua haujlwm ruaj khov hauv kev xav tau ib puag ncig kev lag luam. Kev sib xyaw ua ke ntawm kev tsim khoom, kev tswj cov khoom siv, thiab kev ua tiav saum npoo ua rau cov kav dej honing tseem ceeb rau kev ua haujlwm siab - hydraulic systems thoob ntiaj teb kev lag luam.
