Lub nplhaib forgings yog ib yam khoom ntawm kev lag luam forging thiab ib hom forging. Lawv yog cov khoom zoo li lub nplhaib uas tau tsim los ntawm kev siv lub zog sab nraud rau cov hlau hlau (tsis suav cov phaj) thiab ua rau lawv tsim nyog compression rog los ntawm cov yas deformation. Lub zog no feem ntau ua tiav los ntawm kev siv rauj lossis lub siab. Cov txheej txheem forging tsim cov qauv ua kom zoo dua qub thiab txhim kho lub cev ntawm cov hlau. Lub nplhaib forgings tuaj yeem pom txhua qhov chaw hauv lub neej niaj hnub thiab yog cov khoom lag luam.
Cov txheej txheem ntau lawm
1. zawv zawg hlau blanking: Txiav cov hlau ingot rau hauv qhov loj thiab qhov hnyav raws li cov khoom xav tau.
2.Heating (xws li tempering): Cov khoom siv cua sov feem ntau muaj xws li ib chav chamber rauv, thawb qws rauv thiab rooj annealing rauv. Txhua qhov cub cua sov siv cov pa roj carbon monoxide ua roj.
Cov cua kub ntawm cov hlau ingot feem ntau yog 1150 ℃ ~ 1240 ℃. Lub sij hawm cua sov ntawm txias steel ingot yog li 1 mus rau 5 teev, thiab lub sij hawm cua sov ntawm kub steel ingot yog ib nrab ntawm lub sij hawm cua sov ntawm txias steel ingot. Lub rhuab steel ingot nkag mus rau txheej txheem forging.
3. Forging: Lub steel ingot rhuab mus txog 1150 ~ 1240 ℃ yog tshem tawm ntawm lub cua sov rauv, thiab ces muab tso rau hauv cov cua rauj los yog electro-hydraulic rauj los ntawm tus neeg teb xov tooj. Raws li qhov loj ntawm cov hlau ingot thiab forging piv yuav tsum tau, qhov sib thooj roughening, kos duab thiab lwm yam txheej txheem yog nqa tawm, qhov loj ntawm forging yog soj ntsuam nyob rau hauv lub sij hawm, thiab forging kub yog tswj los ntawm ib tug infrared tus pas ntsuas kub.
4. Kev tshuaj xyuas: Kev tshuaj xyuas ua ntej ntawm forging dawb paug yog nqa tawm, feem ntau yog qhov kev kuaj pom thiab qhov loj me. Hais txog qhov tsos, qhov kev tshuaj xyuas tseem ceeb yog seb puas muaj qhov tsis xws li cov kab nrib pleb. Nyob rau hauv cov nqe lus ntawm qhov loj me, cov npoo dawb paug yuav tsum tau lees tias nyob rau hauv cov cai ntawm daim duab kos, thiab cov ntaub ntawv yuav tsum tau khaws cia.
5. Thaum tshav kub kub kev kho mob: Thaum tshav kub kub lub forging mus rau ib tug predetermined kub, cia nws sov rau ib lub sij hawm ntawm lub sij hawm, thiab ces txias nws nyob rau hauv ib tug predetermined ceev los txhim kho lub internal qauv thiab kev ua tau zoo ntawm forging. Lub hom phiaj yog tshem tawm cov kev ntxhov siab sab hauv, tiv thaiv deformation thaum lub sij hawm machining, thiab kho hardness kom lub forging yooj yim txiav. Tom qab kev kho cua sov, cov hlau ingot yog cua txias los yog dej txias thiab quenched raws li cov khoom xav tau.
6. Rough processing: Tom qab lub forging yog tsim, nws yog ua tiav rau hauv forgings ntawm ntau yam specifications raws li cov khoom yuav tsum tau.
7. Ultrasonic flaw detection: Tom qab lub forging txias, qhov kub poob mus txog 20 ℃ rau ultrasonic flaw nrhiav kom tau raws li lub teb chaws tus qauv Ⅰ, Ⅱ, Ⅲ thiab lwm yam qauv thiab nto defect tshuaj xyuas.
8. Kev ntsuas khoom siv tshuab: txhawm rau ua kom tau raws li cov neeg siv khoom xav tau, cov khoom siv kho tshuab ntawm cov forgings yuav tsum tau sim, feem ntau yog tawm los, tensile, cuam tshuam thiab lwm yam kev sim. Lub tuam txhab cov cuab yeej ntsuas tseem ceeb suav nrog 1 universal mechanical properties tester, 1 impact tester, 1 nruam steel bar dotting machine, 1 ultrasonic flaw detector, 1 magnetic particle flaw detector, 2 thermometers, 1 power two-blade broaching machine, 1 impact cryostat, 1 metallographic microscope, 1 metallographic pre-grinder, 1 metallographic txiav tshuab, 2 Brinell hardness testers, thiab lwm yam., uas tuaj yeem ua tau raws li cov kev xav tau ntawm niaj hnub kuaj ntawm ntau yam forgings.
9. Kev soj ntsuam zaum kawg: Cov forgings tiav thaum kawg raug tshuaj xyuas kom ntseeg tau tias qhov zoo ntawm forgings yog du thiab tsis muaj qhov tsis xws luag xws li tawg, thiab qhov ntev yog nyob rau hauv qhov yuav tsum tau ntawm cov duab kos thiab raug kaw.
10. Warehousing: Tom qab kev soj ntsuam zoo, cov forgings tiav tsuas yog ntim thiab muab tso rau hauv cov khoom tiav warehouse rau cov khoom xa tuaj.
Daim ntawv thov teb ntawm lub nplhaib forgings yog: Diesel nplhaib forgings: ib hom diesel cav forgings. Diesel cav yog ib hom tshuab fais fab, thiab lawv feem ntau siv los ua cav. Siv cov cav loj diesel ua piv txwv, cov forgings siv xws li lub tog raj kheej taub hau, cov ntawv xov xwm tseem ceeb, crankshaft kawg flange tso zis kawg shafts, txuas rods, piston rods, piston hau, crosshead pins, crankshaft kis gears, iav rings, intermediate gears, thiab roj twj tso kua mis. cev, etc.
Lub nplhaib forgings muaj keeb kwm ntau txhiab xyoo hauv kuv lub tebchaws. Tshuab forging yog nqa tawm siv cov cuab yeej forging ntawm ntau yam khoom siv forging. Tshuab forging tuaj yeem muab faib ua plaub pawg raws li cov khoom siv thiab cov cuab yeej siv: dawb forging, qauv forging, tuag forging thiab tshwj xeeb forging.
Txhua yam txaus siab rau peb cov khoom, thov hu rau peb rau ib daim ntawv teev npe ntawmdella@welonchina.com. Thankkoj!
