(1) Siv cov cuab yeej siv siab thiab ntsuas ntsuas los tshuaj xyuas cov pwm qhov tseeb, qhov nyuaj, thiab qhov roughness ntawm ob qho tib si hauv online thiab offline. Sau thiab sau npe pwm uas dhau kev tshuaj xyuas, muab tso rau hauv pwm cia, thiab thaum siv, tshem tawm cov pwm polished ua hauj lwm inserts. Sib dhos thiab xyuas cov pwm pwm, pwm pwm, thiab pwm pwm, thiab xa mus rau lub tshuab cua sov ib zaug paub tseeb tias yog lawm.
(2) Preheating qhov yuav tsum tau rau txhuas profile extrusion pwm ua ntej mounted: extrusion lub tog raj kheej: 400-450 degree, extrusion ncoo: 350 degree, pwm ncoo: 350-400 degree, tiaj tus tuag: 450-470 degree, tis tuag: 460-480 degree; Lub sij hawm rwb thaiv tsev yuav tsum raug xam raws li pwm tuab (1.5-2 feeb / hli).
(3) Lub sij hawm cua sov rau txhuas profile extrusion pwm nyob rau hauv lub cub tawg yuav tsum tsis pub tshaj 10 teev; Yog tias lub sijhawm ntev dhau lawm, cov pwm ua haujlwm tuaj yeem yooj yim corrode lossis deform.
(4) Thaum pib ntawm aluminium alloy profile extrusion, siab yuav tsum tau maj mam, raws li kev cuam tshuam quab yuam tuaj yeem yooj yim ua rau pwm thaiv. Yog tias muaj teeb meem tshwm sim, nres lub tshuab tam sim ntawd kom tsis txhob crushing cov pwm ua haujlwm ntxig.
(5) Tom qab tshem cov pwm los ntawm lub tshuab, tos kom txog thaum nws txias mus rau 150-180℃ua ntej muab tso rau hauv lub caustic tov rau leaching, vim leaching ntawm kub kub yuav ua rau tawg vim thermal shock. Advanced etching txoj kev yuav tsum tau siv los rov qab thiab txuag cov tshuaj caustic, txo lub sij hawm corrosion, thiab ua kom muaj kuab paug- ntxuav dawb.
(6) Thaum kho aluminium profile extrusion pwm thiab sib dhos tis tuag, siv tus pas nrig tooj liab los kais maj mam; tsis txhob siv ib lub rauj loj los ntaus quab yuam, kom tsis txhob muaj zog ntau dhau uas tuaj yeem ua rau pwm puas.
(7) Ua ntej nitriding, qhov chaw ua hauj lwm ntawm txhuas extrusion tuag yuav tsum tau ua tib zoo polished rau ib tug nto roughness ntawm Ra 0.8-0.4 μm;
(8) Aluminium extrusion tuag yuav tsum tau ntxuav kom huv si ua ntej nitriding, thiab tsis pub roj nkag mus rau hauv lub cub tawg; cov txheej txheem nitriding yuav tsum tsim nyog (nyob ntawm cov khoom siv thiab cov khoom siv tuag). Tom qab nitriding, qhov tawv tawv yuav tsum yog HV900-1200. Ib txheej tuab heev lossis tawv nitriding tuaj yeem ua rau tev. Feem ntau, ib txheej ntawm cov tuag tuaj yeem raug nitrided 3-5 zaug; complex high-ntau lub fin radiator profile tuag tsis dhau nitriding;
(9) Rau cov tuag tshiab, bar tuag, thiab tubing tuag ntawm cov khoom uas twb muaj lawm, nitriding tuaj yeem ua tiav yam tsis muaj kev sim extrusion; cov khoom tshiab thiab complex profile tuag yuav tsum dhau mus sim extrusion ua ntej nitriding;
(10) Tom qab ib tug tshiab txhuas extrusion tuag dhau mus sim extrusion, nws yuav tsum tau muab tshem tawm rau nitriding tom qab extruding tsis ntau tshaj 10 ingots kom tsis txhob rub lub chaw ua hauj lwm nto ntawm lub grooves. Kev tsim tawm ntau dhau ntawm ob txoj kev kho nitriding yuav tsum raug zam -feem ntau 60-100 ingots rau cov tuag tuag thiab 40-80 ingots rau manifold tuag; Kev tsim tawm ntau dhau tuaj yeem ua rau cov txheej txheem nitriding tawg.
(11) Tom qab siv, aluminium extrusion tuag yuav tsum tau polished thiab oiled ua ntej cia.
