1. Dab tsi yog cov kauj ruam tseem ceeb hauv kev ua kom txias txias - kos lub raj ntau lawm?
Teb:Cov txheej txheem tsim khoom suav nrog:
Kev xaiv khoom siv:Siab - zoo seamless raj (carbon / alloy steel, stainless hlau)
Annealing:Softens cov khoom kom zoo dua ductility ua ntej txias txias
Pickling & Lubrication:Tshem cov nplai thiab siv cov roj nplaum kos duab
Kev kos duab txias:Rub los ntawm cov tuag kom txo txoj kab uas hla thiab txhim kho precision
Kev ua tiav kawg:Straightening, txiav, kho cua sov, thiab nto tiav
2. Hom kev kos duab txias yog siv li cas?
Teb:Cov txheej txheem ntau:
Sinking:Txoj kev yooj yim tshaj plaws siv tsuas yog tuag (tsis muaj mandrel)
Plug Drawing:Siv mandrel nyob ruaj ruaj rau kev tswj ID zoo dua
Mandrel Drawing:Ua haujlwm txav mandrel rau siab precision
Tube Txo:Ntau yam tuag nyob rau hauv series rau gradual loj txo
3. Kev kos duab txias ua kom cov khoom zoo li cas?
Teb:Cov txiaj ntsig muaj xws li:
Ua kom muaj zog:Ua hauj lwm hardening txhim kho tensile zog los ntawm 20-40%
Enhanced Precision:Ua kom nruj kam rau ua (± 0.05mm)
Superior Surface Finish:Hom Ra 0.8-3.2 μm
Zoo dua Grain Structure:Aligns grain flow rau txhim kho mechanical zog
4. Dab tsi tom qab- kev kho kos duab raug siv?
Teb:Common finishing txheej txheem:
Stress Relieving:Tsawg-kub annealing los txo cov kev ntxhov siab seem
Precision sib tsoo:Rau ultra- nruj kam rau ua (± 0.01mm)
Polishing:Rau daim iav-zoo li qhov chaw (Ra<0.4 μm)
Tsis yog -Kev kuaj kev puas tsuaj:Ultrasonic / eddy soj ntsuam tam sim no
5. Cov qauv zoo dab tsi siv rau cov raj txias -txuas?
Teb:Cov ntsiab lus tseem ceeb:
Dimensional Standards:ASTM A519, DIN 2391, EN 10305
Nto Zoo:Tsis muaj kab nrib pleb, pits, thiab kos cim
Mechanical Properties:Tshawb xyuas los ntawm kev sim tensile/hardness
Ncaj nraim:Feem ntau Tsawg dua los yog sib npaug li 1 hli ib 'meter' ntev
