Skived thiab Roller Burnished Tubes
Skived thiab cov menyuam kub hnyiab cov raj sawv cev rau qhov tseem ceeb hauv kev tsim cov siab -precision, seamless hydraulic thooj voos kheej kheej. Qhov no ob -theem txias- txheej txheem ua hauj lwm hloov ib tug ntxhib, honed, los yog extruded steel raj rau hauv ib feem nrog tshwj xeeb nto cov yam ntxwv thiab qhov ntev qhov tseeb, ua rau nws zoo tagnrho rau kev thov hydraulic thiab pneumatic daim ntaub ntawv.
Hauj lwm lawm
Skived thiab cov menyuam kub hnyiab cov raj sawv cev rau qhov tseem ceeb hauv kev tsim cov siab -precision, seamless hydraulic thooj voos kheej kheej. Qhov no ob -theem txias- txheej txheem ua hauj lwm hloov ib tug ntxhib, honed, los yog extruded steel raj rau hauv ib feem nrog tshwj xeeb nto cov yam ntxwv thiab qhov ntev qhov tseeb, ua rau nws zoo tagnrho rau kev thov hydraulic thiab pneumatic daim ntaub ntawv.
Cov txheej txheem pib nrog skiving. Hauv thawj theem no, ib qho -taw tes txiav cov cuab yeej hla dhau ntawm lub raj ntawm lub raj. Nws lub luag haujlwm tseem ceeb yog tshem tawm cov txheej txheem tswj hwm ntawm cov khoom siv sab hauv. Qhov no ua tiav ob lub hom phiaj tseem ceeb: nws tshem tawm qhov tsis zoo ntawm qhov chaw thiab qhov tsis sib xws los ntawm cov khoom siv hauv paus, thiab nws tsim kom muaj qhov kawg sab hauv txoj kab uas hla nrog qhov ntev nruj heev. Skiving zoo npaj ib lub canvas zoo kawg nkaus rau cov kauj ruam tseem ceeb tom ntej.
Qhov thib ob theem yog roller burnishing. Qhov no yog txheej txheem chipless xov uas hardened, precision chais raug yuam nyob rau hauv siab siab tiv thaiv skived puab nto. Cov rollers txias- ua haujlwm cov hlau, compressing lub ncov ntawm lub microscopic nto profile rau hauv hav. Cov yas deformation no ua rau muaj txiaj ntsig ntau:
Kev sib xyaw ua ke ntawm cov txheej txheem no ua rau lub raj muaj kev ua haujlwm tsis sib xws. Lub skiving kom zoo meej geometry thiab loj, thaum cov menyuam burnishing optimizes nto kev ncaj ncees. Yog li ntawd, cov raj no yog qhov kev xaiv zoo tshaj plaws rau hydraulic thooj voos kheej kheej hauv cov tshuab hnyav, cov khoom siv hauv tsev, thiab kev siv xov tooj ntawm tes uas muaj kev ntseeg siab, kev ua haujlwm, thiab kev ua haujlwm ntev yog qhov tseem ceeb. Lawv qhov tsis zoo seamless thiab zoo kawg nkaus ua tiav ua rau txo qis kev ua haujlwm los ntawm kev sib txhuam, txo qis, thiab txo qis sijhawm.
