Qhib forging qhov chaw

Cov txheej txheem yooj yim ntawm kev forging muaj xws li chim siab, elongation, xuas nrig ntaus, khoov, twisting, tshem tawm, txiav, thiab forging.

Dawb forging elongation

Elongation, tseem hu ua kev txuas ntxiv, yog txheej txheem forging uas txo qhov ntu ntu ntawm qhov billet thiab nce nws qhov ntev.Elongation feem ntau yog siv rau forging pas nrig thiab ncej qhov chaw.Muaj ob txoj hauv kev ntawm elongation: 1. elongation ntawm lub tiaj tiaj tiaj.2. Nthuav rau ntawm tus pas nrig.Thaum lub sij hawm forging, cov tub ntxhais pas nrig yog muab tso rau hauv lub punched dawb paug thiab ces elongated raws li ib tug khoom dawb paug.Thaum kos duab, nws feem ntau tsis ua tiav hauv ib qho mus.Qhov dawb paug yog thawj zaug kos rau hauv cov duab hexagonal, forged mus rau qhov xav tau ntev, tom qab ntawd chamfered thiab sib npaug, thiab tus pas nrig tseem raug tshem tawm.Txhawm rau kom yooj yim tshem tawm cov tub ntxhais pas nrig, qhov chaw ua haujlwm ntawm cov tub ntxhais pas nrig yuav tsum muaj txoj kab nqes ntawm ib ncig ntawm 1: 100.Txoj kev elongation no tuaj yeem ua kom qhov ntev ntawm lub hollow billet, txo cov phab ntsa thickness, thiab tuav lub puab txoj kab uas hla.Nws yog feem ntau siv rau forging lub tes tsho hom ntev hollow forgings.

Free forging thiab chim siab

Upsetting yog ib qho txheej txheem forging uas txo qhov siab ntawm qhov khoob thiab ua rau qhov chaw hla ntu.Cov txheej txheem chim siab yog tsuas yog siv rau forging iav blanks thiab ncig ncuav mog qab zib forgings.Cov txheej txheem ntxhov siab tuaj yeem txhim kho microstructure ntawm billet thiab txo cov anisotropy ntawm txhua yam khoom.Cov txheej txheem rov ua dua ntawm kev ntxhov siab thiab elongation tuaj yeem txhim kho qhov kev ua kom zoo thiab kev faib tawm ntawm carbides hauv cov cuab yeej siab alloy steel.Muaj peb yam tseem ceeb ntawm kev ntxhov siab: 1. Ua kom ntxhov siab.Kev ntxhov siab ua tiav yog cov txheej txheem ntawm kev tso cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.2. Xaus kev chim siab.Tom qab cua sov qhov khoob, ib qho kawg yog muab tso rau hauv lub phaj xau los yog lub log pwm kom txwv cov yas deformation ntawm qhov no, thiab tom qab ntawd lwm qhov kawg ntawm qhov khoob yog hammered los tsim kev ntxhov siab.Txoj kev chim siab ntawm kev siv daim hlau uas ploj lawm feem ntau yog siv rau cov khoom me me;Txoj kev chim siab ntawm lub log tsheb pwm feem ntau yog siv rau ntau lawm.Nyob rau hauv ib qho kev tsim khoom, cov khoom uas yuav tsum tau chim siab tuaj yeem ua kom sov hauv zos, lossis cov khoom uas tsis tas yuav chim siab tuaj yeem muab quenched hauv dej tom qab cua sov tag nrho, thiab tom qab ntawd chim siab tuaj yeem nqa tawm.3. Kev ntxhov siab nruab nrab.Txoj kev no yog siv rau forging forgings nrog loj mid-section thiab me kawg seem, xws li iav blanks nrog bosses ntawm ob sab.Ua ntej yuav chim siab rau qhov khoob, ob qhov kawg ntawm qhov khoob yuav tsum tau rub tawm ua ntej, thiab tom qab ntawd lub qhov khoob yuav tsum tau hammered vertically ntawm ob daim hlau xau kom chim rau nruab nrab ntawm qhov khoob.Txhawm rau tiv thaiv kev khoov ntawm lub billet thaum ntxhov siab, qhov piv ntawm billet qhov siab h rau txoj kab uas hla dh / d yog ≤ 2.5.

Dawb forging xuas nrig ntaus

Punching yog txheej txheem forging uas cuam tshuam nrog kev xuas nrig ntaus los yog los ntawm qhov ntawm qhov khoob.Muaj ob txoj hauv kev tseem ceeb ntawm kev xuas nrig ntaus: 1. Ob chav sided xuas nrig ntaus txoj kev.Thaum siv cov xuas nrig ntaus rau qhov tob ntawm 2/3-3/4, tshem tawm cov punch, tig qhov khoob, thiab tom qab ntawd kho cov punch nrog txoj hauj lwm los ntawm sab nraud kom xuas nrig tawm ntawm lub qhov.2. Txoj kev xuas nrig ntaus ib leeg.Txoj kev xuas nrig ntaus ib leeg tuaj yeem siv rau billets nrog me me thickness.Thaum xuas nrig ntaus, qhov khoob yog muab tso rau ntawm lub nplhaib nraub qaum, thiab qhov kawg ntawm ib qho me ntsis tapered punch yog ua raws li txoj haujlwm xuas nrig ntaus.Lub qhov khoob yog hammered nyob rau hauv kom txog thaum lub qhov nkag.
