Kev Tsim Cov Tube Thiab Hlau Hlau Ntawm Tsheb Rooj Ncej
Lub rooj zaum hauv tsheb yog ib qho tseem ceeb ntawm lub tsheb sab hauv, thiab lub rooj zaum ncej yog lub ntsiab ntawm lub rooj zaum. Lub ntsiab raw khoom ntawm lub rooj zaum ncej yog steel kav thiab hlau hlau, nyob rau hauv tsab xov xwm no peb yuav qhia txog ib co tsim xim ntawm ob qhov chaw.
1, Kev faib cov yeeb nkab steel
Raws li cov txheej txheem tsim, steel yeeb nkab tau muab faib ua seamless steel yeeb nkab thiab welded steel yeeb nkab. Cov welded steel yeeb nkab feem ntau yog siv rau ntawm tus ncej ntawm lub rooj zaum tsheb, thiab muaj kev sib txuas ncaj nraim ntawm cov yeeb nkab steel.
2. Cov txheej txheem ua haujlwm rau cov yeeb nkab steel
2.1 Bending txheej txheem:
dabtsi yog khoov yog hais txog cov txheej txheem dabtsi yog khoov ntawm lub raj ntawm ntsug lossis kab rov tav dabtsi yog khoov tshuab los ntawm kev siv cov dabtsi yog khoov tuag, clamping thaiv, nias thaiv, thaiv thaiv qhov thaiv, mandrel, thiab lwm yam khoom siv.
2.2 Compression dabtsi yog khoov
Cov txheej txheem dabtsi yog khoov yog ib txoj kev ua uas tso cov raj hlau rau ntawm lub pendulum thaiv thiab siv cov kev hloov pauv mus rau lub raj los ntawm kev siv cov tuag kom ua tiav lub hom phiaj ntawm kev khoov thiab sib sau.
2.3 Push dabtsi yog khoov
Cov txheej txheem thawb bending yog hais txog lub raj tsim txoj kev thawb thiab khoov los ntawm kev siv cov tuag ntawm lub tshuab xovxwm raws lub raj axial siab.
2.4 Rolling dabtsi yog khoov
Rolling thiab dabtsi yog khoov txheej txheem hais txog cov txheej txheem ntawm kev tsim cov raj los ntawm kev siv peb lub log tsav tsheb ntawm dov thiab dabtsi yog khoov tshuab. Yob dabtsi yog khoov tsuas yog haum rau tuab phab ntsa yeeb nkab uas yuav tsum tau loj vojvoog ntawm curvature.
3. Kev txwv qhov ntev ntawm cov yeeb nkab
3.1 Yam tsawg kawg bending vojvoog
Qhov tsawg kawg nkaus dabtsi yog khoov vojvoog ntawm cov yeeb nkab qhov chaw yog raws li qhia nyob rau hauv daim duab, feem ntau yog ntau tshaj 2 npaug ntawm lub cheeb txoj kab uas hla ntawm steel yeeb nkab.
3.2 Ntev ntawm qhov ncaj
Yog hais tias nyob rau hauv tib lub dav hlau, qhov nyob ib sab bending nrug yog 1.5 npaug ntawm txoj kab uas hla ntawm lub raj; Yog tias tsis nyob hauv tib lub dav hlau, qhov sib nrug yog 2 npaug ntawm txoj kab uas hla. Qhov kawg ntawm cov yeeb nkab yuav tsum yog tsawg kawg yog 1.5 npaug ntawm cov yeeb nkab txoj kab uas hla.
3.3 Qhov tsawg kawg nkaus punching loj ntawm ib puag ncig yeeb nkab nyob ntawm phab ntsa thickness. Qhov tsawg kawg nkaus yog 3 zaug phab ntsa thickness thiab 5 zaug phab ntsa thickness yog pom zoo.
3.4 Qhov tsawg kawg nkaus txoj kab uas hla ntawm cheeb tsam flattening yog peb npaug ntawm lub thickness ntawm lub flattening cheeb tsam (piv txwv li: phab ntsa thickness yog 1.5 hli, lub thickness ntawm lub flattening cheeb tsam yog 3.0mm, ces qhov tsawg kawg nkaus lub cheeb yog 9mm).
3.5 Qhov siab tshaj plaws hauv zos nias qhov tob ntawm cov yeeb nkab backrest yog 0.5 npaug ntawm cov yeeb nkab txoj kab uas hla.
3.6 Tshem tawm ntawm qhov sib tshooj yog 0.5-1.0mm, thiab qhov chaw vuam yam tsawg kawg nkaus yog 3 hli.
4. Hlau hlau qhov chaw tsim cov txheej txheem yuav tsum tau ua
1. Pom zoo ntev steel hlau:
L tsawg dua los yog sib npaug rau 1000mm, khoov kom muaj nuj nqis: Tsawg dua los yog sib npaug rau 10, ntev los yog ntau dhau lawm bending ntawm steel hlau yuav ua rau tus nqi tsim khoom.
2, khoov qhov sib txawv
1) Yog tias nyob rau hauv tib lub dav hlau, qhov tsawg kawg nkaus qhov sib nrug yog 1 npaug ntawm txoj kab uas hla ntawm cov hlau hlau;
2) Yog tias tsis nyob hauv tib lub dav hlau, qhov tsawg kawg nkaus qhov sib txawv yog 1.5 npaug ntawm txoj kab uas hla ntawm cov hlau.
3. Txhua qhov dabtsi yog khoov radii yuav tsum tau sib koom ua ke kom deb li deb tau kom txo tau tus nqi, qhov tsawg kawg nkaus hauv qhov khoov lub vojvoog yuav tsum siab dua lossis sib npaug ntawm txoj kab uas hla ntawm cov hlau hlau.
4. Zam kev sib cuag ntawm qhov kawg-rau-kawg qauv, yog tias tus qauv xav tau, qhov kev ncua deb ntawm qhov qhib qhov loj yuav tsum siab dua lossis sib npaug ntawm 25mm.
Cov saum toj no yog qee qhov kev siv ntau txoj hauv kev ntawm lub rooj zaum ncej. Cov txheej txheem txheej txheem ntawm CBIES Hoobkas npog cov txheej txheem ua.
