Preheating thiab chim siab yog cov txheej txheem tseem ceeb hauv aluminium pas nrig taub qab vuam tshuab. Kab lus no muab cov ntsiab lus ntawm cov kauj ruam tseem ceeb, lawv qhov tseem ceeb, thiab lawv lub luag haujlwm hauv kev ua tiav kev ua tiav aluminium rod welds.
1. Preheating:
- Qhov tseem ceeb:Preheating npaj cov txhuas rods rau vuam los ntawm kev txo qhov kev pheej hmoo ntawm kev tawg thiab txhawb kev fusion zoo dua.
- Txheej txheem piav qhia:Preheating yuav maj mam ua kom sov tus pas nrig xaus rau qhov kub thiab txias ua ntej vuam. Qhov ntsuas kub no yog txiav txim siab los ntawm cov khoom xws li aluminium alloy, qhov ntev ntawm cov pas nrig, thiab qhov ntsuas vuam. Preheating pab tshem tawm cov dej noo, txo cov thermal poob siab, thiab ua rau cov khoom siv tau zoo dua rau vuam.
2. Kev ntxhov siab:
- Qhov tseem ceeb:Kev ntxhov siab yog tus txheej txheem ntawm deforming tus pas nrig kawg los tsim kom muaj qhov loj dua, tsis sib xws ntawm qhov chaw sib tshooj rau vuam.
- Txheej txheem piav qhia:Thaum chim siab, tus pas nrig kawg yog clamped ruaj ntseg nyob rau hauv lub fixture thiab ces raug rau axial siab. Qhov siab no ua rau tus pas nrig kawg deform, tsim kom muaj thaj chaw loj dua. Tom qab ntawd cov deformed xaus yog coj los ua ke thiab welded. Kev ntxhov siab txhim kho qhov vuam lub zog los ntawm kev ua kom zoo sib xws thiab sib koom ua ke.
3. Preheating thiab Upsetting Sequence:
- Qhov tseem ceeb:Kev ua kom zoo ntawm preheating thiab chim siab yog qhov tseem ceeb rau kev ua tiav welds.
- Txheej txheem piav qhia:Qhov sib lawv liag ntawm preheating thiab upsetting nws txawv nyob ntawm seb lub vuam tshuab thiab daim ntawv thov. Feem ntau, preheating yog ua ntej kom ncav cuag qhov xav tau qhov kub thiab txias, ua raws li kev ntxhov siab los npaj cov pas nrig kawg. Lub tshuab ces pib qhov txheej txheem vuam los tsim kom muaj kev sib koom ua ke zoo.
4. Kev tswj qhov kub thiab txias:
- Qhov tseem ceeb:Kev tswj qhov kub thiab txias yog tsim nyog rau preheating.
- Txheej txheem piav qhia:Aluminium pas nrig taub qab vuam tshuab tau nruab nrog lub tshuab ntsuas kub uas saib xyuas thiab tswj qhov kub ntawm preheating. Qhov no ua kom cov pas nrig ncav cuag qhov ntsuas kub zoo rau qhov tshwj xeeb vuam tsis.
5. Clamping thiab Alignment:
- Qhov tseem ceeb:Kev ruaj ntseg clamping thiab kev sib dhos kom raug thaum ntxhov siab yog qhov tseem ceeb.
- Txheej txheem piav qhia:Lub fixture lub clamping mechanism tuav tus pas nrig xaus kom ruaj khov nyob rau hauv qhov chaw thaum muaj kev ntxhov siab los tiv thaiv kev txav mus los. Precise alignment xyuas kom meej tias cov deformed xaus sib dhos kom raug rau vuam.
6. Vuam txheej txheem:
- Qhov tseem ceeb:Preheated thiab chim siab pas nrig kawg yog npaj rau vuam.
- Txheej txheem piav qhia:Thaum preheating thiab chim siab ua tiav, cov txheej txheem vuam yog pib. Lub tshuab cov kev tswj hwm qib siab, suav nrog tam sim no, qhov hluav taws xob, thiab qhov chaw siab, tau hloov kho kom ntseeg tau tias qhov zoo ntawm vuam zoo. Lub vuam yog tsim nyob rau ntawm qhov deformed kawg, ua rau muaj kev sib koom ua ke muaj zog thiab txhim khu kev qha.
7. Kev soj ntsuam tom qab Weld:
- Qhov tseem ceeb:Kev soj ntsuam xyuas qhov zoo ntawm qhov sib koom ua ke.
- Txheej txheem piav qhia:Tom qab cov txheej txheem vuam, kev soj ntsuam xyuas tom qab vuam yog ua los xyuas qhov tsis xws luag lossis teeb meem. Txhua qhov kev hloov kho uas tsim nyog lossis kev kho yuav raug coj los ua kom muaj kev sib txuas zoo.
Preheating thiab chim siab yog cov kauj ruam tseem ceeb hauv cov txheej txheem aluminium pob tw welding. Cov txheej txheem no npaj cov pas nrig kawg, txhim kho kev sib raug zoo, thiab tsim kom muaj zog, txhim khu kev qha vuam sib koom ua ke. Kev sib txuas kom raug, tswj qhov kub thiab txias, clamping, sib dhos, thiab kev saib xyuas kom muaj kev vam meej welds nyob rau hauv aluminium pas nrig taub qab vuam tshuab, ua rau cov khoom zoo thiab ruaj khov welded.
