Kev kos duab txias ua li cas txhim kho Tube kom raug thiab nto tiav?

Kev kos duab txias yog cov txheej txheem hlau ua tiav uas ua rau muaj txiaj ntsig zoo rau ob qho tib si qhov tseeb thiab qhov chaw tiav ntawm cov hlau lossis hlau hlau. Tsis zoo li kub-khoov cov hlab, uas yog tsim los ntawm qhov kub thiab txias thiab nthuav qhia qhov ntsuas, ovality, thiab dav dua, qhov txias - cov raj tau txais cov yas deformation ntawm chav tsev kub los ntawm kev tuag thiab mandrel system - ua rau cov khoom zoo tshaj plaws thiab zoo nkauj.

1. Txhim kho Dimensional raug

Thaum lub sij hawm txias txias, lub raj yog rub los ntawm ib tug hardened steel tuag (rau txheej txoj kab uas hla tswj) thiab tshaj ib tug precision mandrel (rau sab hauv txoj kab uas hla tswj). Qhov no dual - ua:

- Txo cov phab ntsa thickness thiab txoj kab uas hla nrog nruj tolerances (feem ntau ± 0.05 hli los yog zoo dua);

- Txhim kho roundness thiab ncaj los ntawm kev tshem tawm ovality thiab hneev nti;

- Ua kom cov phab ntsa tuab tuab raws tag nrho qhov ntev, qhov tseem ceeb rau kev siv hydraulic lossis siab.

Qhov tsis muaj thermal expansion/contraction (tsis zoo li kub dov) tshem tawm cov ncej -txias distortion, yielding zoo ib yam geometry zoo tagnrho rau precision sib dhos.

2. Superior nto tiav

Cov txheej txheem kos duab txias smooths lub raj nto los ntawm:

- Ua hauj lwm hardening thiab burnishing: Raws li cov hlau ntws los ntawm polished tuag, nto asperities yog compressed thiab sheared tawm, ua ib tug kaj, reflective tag;

- Tshem tawm ntawm cov nplai zeb: Txij li thaum cov duab txias pib nrog descaled (piv txwv li, pickled) tubing, cov khoom kawg yog dawb ntawm oxides thiab pits;

- Tsawg qhov roughness: Hom Ra qhov tseem ceeb ntawm 0.2 txog 1.6 μm, haum rau plating ncaj, txheej, lossis siv hauv cov khoom pom.

3. Txhim kho cov cuab yeej cuab tam

Kev ua haujlwm txias ua rau muaj zog tensile thiab hardness los ntawm kev sib zog hardening, thaum tuav cov ductility zoo - ua lub raj zoo tagnrho rau kev siv cov qauv, tsheb, thiab hydraulic qhov twg lub zog - rau - qhov hnyav piv tseem ceeb.

4. Tsis muaj cua sov-Teb chaws cuam tshuam

Vim hais tias cov txheej txheem tshwm sim hauv qab qhov kub ntawm recrystallization, tsis muaj grain coarsening los yog decarburization, khaws cia cov khoom ncaj ncees thiab ua kom muaj kev tswj xyuas zoo dua.

Kev kos duab txias hloov pauv qhov ntxhib, loj loj kub- cov raj ua tiav rau hauv siab -precision, du- cov khoom siv saum npoo av npaj rau kev thov cov ntawv thov- yam tsis tas yuav tsum tau siv lub tshuab thib ob. Qhov no ua rau txias txias -cov tub raj yog qhov kev xaiv zoo tshaj plaws rau hydraulic thooj voos kheej kheej, kev poob siab absorbers, precision shafts, thiab automotive qhov chaw uas muaj kev ntseeg siab, haum, thiab ua tiav tsis yog- sib tham.
