Honed Cylinder Tube
Honed lub tog raj kheej raj yog siab -precision seamless los yog welded steel hlab uas tau txais kev tshwj xeeb hauv kev ua tiav kom ua tiav qhov zoo tshaj plaws, qhov tseeb, thiab cov khoom siv kho tshuab. Lawv ua lub luag haujlwm tseem ceeb hauv hydraulic thiab pneumatic thooj voos kheej kheej, qhov chaw hauv qhov chaw du thiab nruj tolerances yog qhov tseem ceeb rau kev ua haujlwm zoo thiab txhim khu kev qha.

Honed lub tog raj kheej raj yog siab -precision seamless los yog welded steel hlab uas tau txais kev tshwj xeeb hauv kev ua tiav kom ua tiav qhov zoo tshaj plaws, qhov tseeb, thiab cov khoom siv kho tshuab. Lawv ua lub luag haujlwm tseem ceeb hauv hydraulic thiab pneumatic thooj voos kheej kheej, qhov chaw hauv qhov chaw du thiab nruj tolerances yog qhov tseem ceeb rau kev ua haujlwm zoo thiab txhim khu kev qha.
Cov raj no yog tsim los ntawm ntau qib ntawm cov hlau xws li E355 / ST52, C20, CK45, Q355B / D, SAE1026, thiab cov hlau alloy xws li 4130 thiab 4140, ua raws li cov qauv thoob ntiaj teb suav nrog DIN 2391, EN 10305, ASTM GB / 9. ua tib zoo tswj kom ntseeg tau tias qhov kev ua haujlwm zoo tshaj plaws thiab kev ua haujlwm ntawm weldability.
Cov txheej txheem tsim khoom feem ntau suav nrog kev kos duab txias ua raws li kev ntxhov siab (BK + S mob) txhawm rau txhim kho cov khoom siv kho tshuab thiab ua kom muaj qhov ruaj khov. Qhov kev kho no ua rau muaj zog tensile xws li 520 MPa mus rau ntau dua 600 MPa, nrog cov txiaj ntsig zoo ntawm 375-520 MPa nyob ntawm cov khoom siv qib, muab kev tiv thaiv zoo heev rau deformation nyob rau hauv kev kub siab.
Cov txheej txheem honing nws tus kheej tshem tawm me me imperfections los ntawm lub raj lub puab nto thiab tsim ib tug ntoo khaub lig-hatch qauv uas pab kom zoo lubrication thiab sealing kev ua tau zoo. Rau cov kev xav tau ntau dua, Skived thiab Roller Burnished (SRB) thev naus laus zis yog ua haujlwm, ua tiav qhov roughness qhov tseem ceeb tsawg li Ra 0.1-0.4 μm piv rau cov qauv honed tiav ntawm Ra 0.4-0.8 μm.
Cov kev qhia tshwj xeeb muaj xws li sab hauv txoj kab uas hla ntawm H8 lossis H9, sab nraud ntawm 40-480 hli, phab ntsa thickness kam rau ua ntawm ± 5% mus rau ± 10% nyob ntawm qhov ntev, thiab ncaj nraim nyob rau hauv 0.5-1 hli ib 'meter'. Muaj qhov ntev ntev mus txog 12 meters, nrog rau ob qho tib si ruaj thiab random ntev muab kom tau raws li cov kev thov tshwj xeeb.
Cov raj precision no pom cov ntawv thov tseem ceeb hauv hydraulic thooj voos kheej kheej rau kev siv tshuab, kev lag luam xovxwm, cov cuab yeej txhaj tshuaj molding, mobile cranes, tshuab ua liaj ua teb, thiab ntau yam kev lag luam automation. Kev sib xyaw ua ke ntawm qhov chaw zoo kawg nkaus, kev tswj xyuas qhov tseeb, thiab cov khoom siv kho tshuab txhim khu kev qha ua kom muaj kev sib txhuam tsawg, txo hnav, ncua lub neej foob, thiab txhim kho tag nrho kev ua haujlwm ntawm hydraulic systems.
Cov txheej txheem kev lees paub zoo suav nrog kev sim nruj ntawm cov khoom siv kho tshuab, kev kuaj xyuas qhov ntev, thiab ntsuas qhov roughness ntawm qhov chaw, kom ntseeg tau tias txhua lub raj honed ua tau raws li qhov xav tau ntawm cov khoom siv niaj hnub hydraulic thoob plaws ntau yam kev lag luam thoob ntiaj teb.
