Cov ntsiab lus tseem ceeb ntawm kev ua cov thev naus laus zis thiab kev tswj hwm zoo rau kev taug
Dab tsi yog cov cuab yeej ua tseem ceeb ntawm cov nqaj? Dab tsi yog qhov kev tswj hwm zoo ntawm txhua lub thev naus laus zis yog dab tsi?
Cov cuab yeej ua haujlwm tseem ceeb ntawm cov nqaj muaj xws li RAILS suav nrog kub dov, txias, ua kom ncaj, txiav, vuam, thiab kev kho kom nto. Cov txheej txheem kub yob yuav tsum tau tswj lub cua sov kub ntawm 1200 {}}}} cov nplej ua kom ntseeg tau tias yog overheating, uas cuam tshuam rau lub zog. Cov txheej txheem cua txias ua rau muaj cov thev naus laus zis ntawm 5 {}} 10℃/ s los tiv thaiv kev ntxhov siab sab hauv thiab kev tawm tsam kev tawm tsam. Tus txheej txheem ncaj yuav tsum tswj hwm lub zog ncaj kom ntseeg tau tias qhov kev tsheb ciav hlau ncaj qha dua lossis muaj sib npaug rau 0.3mm / m thiab zam kev ntxhov siab theem nrab los ntawm kev ncaj ncees ntau dhau. Kev txiav txoj kev siv ntshav lossis nplaim taws txiav nrog ib tug bevel trompendularity yuam kev tsawg dua los yog sib npaug rau 0.5 hli kom tsis txhob muaj burrs cuam tshuam rau vuam vuam tom qab. Cov txheej txheem vuam yuav tsum sib phim ntawm cov vuam qhov tsis sib xws ntawm cov khoom, tswj lub weld dav thiab qhov siab, thiab ua kom tsis muaj qhov tsis xws luag thiab ua kom tsis txhob muaj qhov tseeb thiab ua kom pom kev zoo nkauj thiab ua kom tawg. Cov kev kho deg yuav tsum tau tshem tawm cov nplai; Ntsia hauv cov ntug hiav txwv tseem xav tau kev tiv thaiv corrosion ntxiv kom muaj xeb tsis muaj xeb ntawm qhov chaw. Yuav tsum tau saib xyuas tiag tiag tiag yog qhov yuav tsum tau rau txhua txoj kev kom tsis txhob muaj kev cuam tshuam rau kev sib txawv ntawm kev ua kom zoo.
Dab tsi yog qhov tseem ceeb ntawm kev ua lag luam siv tshuab thiab tswj kev tswj ntawm elastic clips?
Kev lag luam siv tshuab ntawm cov clips sib xyaw suav nrog bleeping, khoov kev, kev kho cua sov, ua kom kho kom sov, thiab tshuaj xyuas cov khoom tiav. Blanking yuav tsum muaj siab - precision txiav ntau dua lossis sib npaug rau ± 0.5mm, tso lub hauv paus rau kev tsim vaj tse tom ntej. Dab tuag yog ua los ntawm tuag nias nrog kev tuag precision ntawm 0.05 hli kom ntseeg tau tias tus qauv tsim qauv thiab lub zog clamp yog nce mus rau tus qauv. Kev kho cua sov yog cov txheej txheem tseem ceeb: qhov ntsuas kub quenching Kev Kho Mob Hauv Kev Kho Mob Caum, cov roj av lossis galvanizing; Kev txhaj tshuaj peenate siv yuav tsum ncav cuag 0.3-0.5mmA los txhim kho saum npoo hardness thiab qaug zog tsis kam. Cov khoom lag luam tiav tag nrho yuav tsum kuaj cov pob zeb ua kom zoo nkauj thiab sib txawv clormation tsawg dua lossis sib npaug ± 1 lab lub neej loj dua los yog sib npaug. Cov khoom lag luam tsis tsim nyog yog nruj me ntsis txwv tsis pub tawm hauv lub hoobkas.
Cov txheej txheem Forging thiab Kev Tswjhwm Zoo ntawm cov ntses ntses?
Ntses cov phiaj feem ntau yog kev quav ntsej, nrog cov txheej txheem tseem ceeb suav nrog kev pam, cua sov, kev kho mob, machining, thiab tshuaj xyuas. Blanking yuav tsum xaiv homogeneous steel billets kom tsis txhob muaj qhov tsis xws luag, nrog lub fillet phaus yuam kev tsawg dua lossis sib npaug ± 2%. Lub cua sov kub yog tswj tau ntawm 1100 {{{{} 1150℃los xyuas kom meej cov billet thiab zam kev tawg los ntawm tsawg-forging. Forging admts Forging kom ntseeg tau tias cov ntses ua tiav lossis sib npaug rau ± 0.3mm, thiab hu rau cov tiaj tiaj tiaj tsis tsawg dua lossis sib luag rau 0.2 hli. Kev kho kom sov thiab tempering thiab tempering kom tswj hwm lub hardness ntawm HB220-260, txhim kho lub zog thiab tawv. Machining tsis tas ua ntej milling ntawm kev tiv toj nto thiab bolt qhov kom ntseeg tau tias roughnness ra tsawg dua los yog sib npaug rau kev teeb tsa. Cov khoom tiav tau xav tau ultrasonic qhov khuam kom kuaj xyuas cov kab nrib sab hauv, thiab tensile lub zog kuaj kom ntseeg tau tias nws tsis tsawg dua 85% ntawm lub hauv paus kav hlau.
Yuav ua li cas cov xov ua lag luam ua ke thiab tswj kev tswj hwm ntawm bolts ua kom ntseeg tau txoj kev sib txuas?
Xov cov lus ua tshuab ntawm bolts suav nrog xov rolling, tig, kev kho cua sov, thiab kev kho kom sov; Tswjhwm ncaj qha cuam tshuam cuam tshuam kev sib txuas kev ntseeg tau. Xov yob yuav tsum tau siab- precision xov dov rau chav kawm ua tiav thiab tsis muaj burrs kom tsis txhob tshaj xov slipping. Qhov tig txheej txheem tswj hwm lub pob tw shank dhuav thiab ntev yuam kev txawv txav tsawg dua lossis sib npaug ntawm ± 0.5mm, yoog raws kev pab cuam. Kev kho kom sov kub kho raws li cov tw qib: Qhov ntsuas kub yog 830-85050℃rau qib 10.9 bolts kom paub meej tias lub hardness thiab lub zog phim. Cov kev kho kom zoo rau cov txheej txheem hauv cov txheej txheem los yog txheej sib npaug ntawm kev sib txuas ntau dua lossis sib npaug nrog 500 teev los tiv thaiv corrosion cuam tshuam rau kev sib txuas. Cov khoom tiav tau yuav tsum tau sim cov xov torque thiab tensque lub zog yog tswj hwm cov qauv qib ua kom ntseeg tau tias muaj kev cia siab.
Dab tsi yog qhov tseem ceeb ntawm cov kev ua kom muaj pwm thiab kev tswj hwm zoo ntawm hauv - rail pads?
Cov thev naus laus zis ntawm - rail pads suav nrog batching suav nrog batching, sib tov, compression, thiab kev kuaj xyuas cov khoom tiav. Batching yuav tsum tau ua kom tiav cov khoom siv raw raws li cov ntaub ntawv yuam kev raws li cov roj hmab, cov neeg sawv cev, thiab muaj sib npaug ± 1% kom ntseeg tau tias cov khoom siv ruaj khov. Kev sib xyaw ua ke los ntawm kev ua yeeb yam sab hauv nrog 100-120℃thiab lub sijhawm ntawm 5-8 feeb los xyuas kom muaj cov khoom siv sib xyaw uas tsis muaj agglomeration. COMPRESSOR MORNING yog nqa tawm ntawm 150-160℃thiab 15-20mpa, nrog lub siab tuav lub sijhawm ntawm 5-10 feeb los xyuas kom muaj qhov tsis meej xws li npuas thiab tsis muaj kua nplaum. Trimming xav tau tshem tawm Flash thiab Burrs, nrog ntug tiaj tus yuam kev tsawg dua lossis sib npaug rau ± 0.3mm kom tsis txhob cuam tshuam haum. Kev Ntsuam Xyuas Cov Khoom Ua tiav yuav tsum muaj kev sim hardness, stiffym me me, thiab sib npaug ntawm ± 5%, thiab kev txo qis tau ua raws li cov kab yuav tsum muaj. Nyob rau tib lub sijhawm, kev xeem laus yog ua kom cov kev pabcuam lub neej ntsib tus qauv.
