Seamless Forged Rings rau Hnyav - Daim Ntawv Thov Ua Haujlwm
Forged nplhaib yog peb lub nplhaib dov tov rau siab - lub zog ncig cov khoom. Nplhaib dov tsim seamless forged rings nrog nruam circumferential lis txaus. Piv nrog rau cov nplhaib tshuab ncaj qha los ntawm cov khoom lag luam, forged rings muab lub zog radial zoo dua, qaug zog ua haujlwm, thiab cuam tshuam tsis kam. Peb lub nplhaib forged pab cua turbine bearing rings, kev tsim kho tshuab slewing rings, roj drilling cuab yeej txuas, hnyav tsheb log hubs, thiab loj flange foob rings. Txhua lub nplhaib forged peb tsim muab kev ntseeg tau tshwj xeeb hauv kev thov thov.
Nplhaib Rolling thiab Kev kho cua sov txheej txheem
Peb lub nplhaib forged blanks yog los ntawm cov koom haum tshwj xeeb ntawm lub nplhaib dov peb tshawb xyuas tsis tu ncua kom ntseeg tau zoo ib yam. Peb ua tiav precision machining hauv peb lub hoobkas. Nplhaib qhov ntau thiab tsawg npog txheej kab Φ200-Φ1500mm, phab ntsa thickness 20-150mm, thiab qhov siab 30-300mm. Cov khoom muaj xws li carbon steel, alloy steel (42CrMo, 34CrNiMo6), stainless hlau, thiab bearing steel (GCr15SiMn). Tom qab dov, rings undergo normalizing lossis quenching + tempering. Rau 42CrMo nyob rau hauv quenched + tempered mob, tensile lub zog mus txog saum 900MPa, yield zog tshaj 750MPa, thiab cuam tshuam lub zog ntawm -40℃nce mus txog saum 27J. Cov khoom no ua tau raws li cov kev cai nruj ntawm cov cua fais fab thiab kev siv tshuab siv.
Deformation Control thiab Precision Machining
Qhov kev sib tw machining rau forged rings yog deformation tswj nyob rau hauv loj nyias -walled lug. Peb machining tov siv ntsug lathes nrog kev cai fixtures. Peb siv cov kev txiav me me thiab ntau qhov dhau los ntawm kev ntxhib, semi-ua tiav, thiab ua tiav theem. Ntuj aging ntawm theem tso tawm kev ntxhov siab. Peb cov rings forged ua tiav IT7 qhov tseeb rau sab nraud thiab sab hauv. Qhov kawg lub ntsej muag flatness yog nyob rau hauv 0.03mm. Phab ntsa thickness sib txawv yog nyob rau hauv 0.05mm. Rau siab- daim ntawv thov precision xws li cua turbine bearing rings, peb muab kev sib tsoo cov kev pab cuam rau IT5 raug thiab Ra tsawg dua los yog sib npaug rau 0.4μm nto tiav. Kev tswj xyuas zoo tsom mus rau kev kuaj ultrasonic rau qhov tsis xws luag sab hauv (kab nrib pleb, suav nrog, cov pob dawb), kev kuaj tawv tawv rau kev tsis sib xws (kev sib txawv hauv ± 20HB), kev tshuaj ntsuam metallographic, thiab CMM qhov ntsuas qhov ntsuas. Ua kom tiav cov ntaub ntawv tshuaj xyuas nrog rau txhua pawg. Standard ntau lawm yog 30-50 hnub. Peb lees txais kev txiav txim los ntawm 1 daim. Standard warranty yog 1 xyoo.
