Cov txheej txheem vuam nyob rau hauv nruab nrab zaus qhov chaw vuam tshuab suav nrog ntau theem sib txawv uas sib sau ua ke rau kev tsim cov welds muaj zog thiab txhim khu kev qha.Kab lus no tshawb txog ntau theem ntawm cov txheej txheem vuam, qhia txog qhov tseem ceeb ntawm txhua theem hauv kev ua tiav cov txiaj ntsig zoo weld.
Cov theem ntawm cov txheej txheem vuam:
- Clamping Phaj:Thawj theem ntawm cov txheej txheem vuam yuav tsum clamping lub workpieces ua ke nyob rau hauv kev tswj lub siab.Kev clamping kom raug ua kom muaj kev sib raug zoo thiab kev hloov pauv kom zoo thaum lub sijhawm tom ntej.
- Pre-Pressing Phase:Nyob rau theem no, ib tug predetermined quab yuam yog siv rau lub workpieces ua ntej welding.Qhov kev nias ua ntej no txo qis qhov sib txawv ntawm qhov chaw, ua kom pom kev sib cuag thiab sib faib cov cua sov.
- Theem cua sov:Cov theem cua sov yog pib los ntawm kev siv vuam tam sim no rau cov lus qhia electrode.Qhov tam sim no ntws los ntawm cov khoom ua haujlwm, ua kom muaj cua sov ua haujlwm ntawm lub interface.Lub tshav kub softens cov khoom thiab tsim ib tug plasticized cheeb tsam ntawm lub sib koom interface.
- Forging Phase:Thaum lub sij hawm forging, cov electrodes exert siab rau cov khoom softened.Qhov siab no ua rau cov khoom siv yas ntws mus, ua kom muaj kev sib txuas ntawm metallurgical raws li qhov chaw sib koom ua ke thiab khov kho.
- Tuav Phaj:Tom qab lub forging theem, lub vuam tam sim no raug hloov, tab sis lub siab yog tswj nyob rau lub sij hawm luv luv.Lub sijhawm tuav no tso cai rau cov khoom siv kom ruaj khov ntxiv, txhim kho kev sib koom ua ke.
- Theem cua txias:Thaum lub sij hawm tuav tiav, cov workpieces raug tso cai kom txias lawm.Kev ua kom txias zoo pab kom tsis txhob muaj kev ntxhov siab ntau dhau thiab cuam tshuam thaum txhawb nqa kev txhim kho microstructure zoo ib yam.
- Tshaj tawm theem:Qhov kawg theem yog tso tawm lub siab ntawm lub workpieces thiab cais cov electrodes.Qhov ua tiav weld raug tshuaj xyuas kom zoo thiab kev ncaj ncees.
Qhov tseem ceeb ntawm txhua theem:
- Kev sib txuas thiab kev sib cuag:Txoj kev clamping thiab pre-pressing kom meej meej kev sib raug zoo thiab kev pom kev sib cuag ntawm lub workpieces, tseem ceeb heev rau uniform cua sov faib.
- Ua kom muaj cua sov zoo:Cov cua sov theem tsim cov cua sov uas yuav tsum tau ua rau cov khoom softening, txhawb kev sib raug zoo metallurgical ntawm kev sib koom ua ke.
- Metallurgical Bonding:Lub forging theem ua kom yooj yim ntws ntawm cov khoom muag muag, ua kom muaj txiaj ntsig zoo ntawm metallurgical bonding thiab kev sib koom ua ke.
- Txhim khu kev ncaj ncees:Lub sijhawm tuav tau txhim kho kev sib koom ua ke los ntawm kev tso cai rau cov khoom siv kom ruaj khov nyob rau hauv siab, txo qhov kev pheej hmoo ntawm qhov tsis xws luag.
- Residual Stress Management:Kev tswj qhov txias kom txo qis qhov kev ntxhov siab seem thiab tiv thaiv kev cuam tshuam, ua kom muaj kev ruaj ntseg nyob rau hauv cov khoom siv welded.
Xaus: Cov txheej txheem vuam nyob rau hauv nruab nrab zaus qhov chaw vuam tshuab muaj ob peb theem tseem ceeb, txhua qhov ua rau kev tsim cov welds zoo.Kev nkag siab thiab kev tswj hwm txhua theem yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo sib xws thiab txhim khu kev qha vuam.Kev ua kom zoo ntawm cov theem no ua rau muaj suab nrov thiab ruaj khov welded pob qij txha uas ua tau raws li cov qauv tsim nyog thiab cov lus qhia tshwj xeeb.
