(1) FFX txoj kev tshuab tuaj yeem tsim cov kav dej nrog cov qib steel siab dua, cov phab ntsa nyias thiab tuab dua.Txij li thaum lub deformation ntawm FFX txoj kev siv tshuab yog tsuas yog raws li kab rov tav yob, thiab ntsug yob nyob rau hauv lub post-rough forming theem tsis tas yuav siv puab yob los tswj deformation, cov khoom qauv muaj cov yam ntxwv ntawm ob softness thiab rigidity, thiab nws. Nws yog ib qho yooj yim kom ua tiav lub zog siab thiab siab rigidity thiab tuaj yeem ruaj khov Ua cov kav dej zoo tshaj 219 hli, D / t = 10 ~ 100, thiab qib steel mus txog P110.
(2) Kab rov tav yob thiab ntsug yob ntawm FFX txoj kev tshuab yog tag nrho sib koom.Nyob rau hauv FFX txoj kev siv tshuab, involute yob puab thiab yob-rau-yob dabtsi yog khoov txoj kev yog organically ua ke, thiaj li hais tias kab rov tav yob thiab ntsug yob tuaj yeem sib koom ua ke.Piv txwv li, peb tiamZTF yob txoj kev tshuabtsim los ntawm ZTZG tsuas yog xav tau los qhia cov txheej txheem rau kev sib sau ntxhib.Nws txo cov nqi ntawm cov menyuam thiab ua kom yooj yim rau kev siv thiab tswj cov yob.
(3) Kev faib tawm ntawm deformation yog tsim nyog thiab cov txheej txheem molding yog ruaj khov.Nyob rau hauv cov txheej txheem ntxhib, txoj kev loj deformation feem ntau yog siv cov kab rov tav, kom qhov curvature ntawm sab ntawm lub raj qhib yog ze rau ntawm cov yeeb nkab tiav lawm, thiab qhov deformation ntawm qhov zoo sib sau yog me me.Qhov no tsim nyog faib ntawm deformation ua rau txoj kev ruaj khov thiab kov yeej qhov tsis zoo ntawm kab yob txoj kev.Qhov kev phom sij zais ntawm welded yeeb nkab tsis zoo yog tshwm sim los ntawm kev faib tsis tsim nyog ntawm deformation.
(4) Txoj kev nruam dabtsi yog khoov txoj kev yog saws los tsim qhov zoo tshaj plaws tej yam kev mob rau high-frequency vuam.FFX txoj kev siv thev naus laus zis tau siv txoj hauv kev nruam dabtsi yog khoov txoj hauv kev thiab ua kom tag nrho kev siv cov yam ntxwv ntawm kab rov tav yob thiab ntsug yob kom tsis muaj qhov tuag ntawm qhov deformation hauv ntu ntu, thiab qhov tseem ceeb tshaj, nws muaj txiaj ntsig zoo ntawm kev deformation los ntawm cov hloov ntawm strip thickness thiab lub zog.Qhov tsis txaus generated elastic rov qab tshwm sim txhim kho molding raug thiab stability.Tom qab kev sib sau ntxhib, ntug ntawm cov hlua hlau yog tag nrho cov yas deformed, thiab qhov curvature ntawm ntug ntawm lub raj qhib yog ze heev rau ntawm lub raj tiav;qhov deformation ntawm qhov zoo sib sau yog me me, thiab cov duab ntawm lub raj qhib tom qab kev sib sau ntxhib yuav tsis hloov, uas ua rau muaj txiaj ntsig zoo rau kev siv vuam ntau zaus.zoo tej yam kev mob.
(5) Txhim kho qhov zoo ntawm cov yeeb nkab welded.Piv nrog rau yob txoj kev siv tshuab, FFX txoj kev siv tshuab kuj txhim kho qhov zoo ntawm cov yeeb nkab welded nyob rau hauv ob yam nram qab no: Ua ntej, tom qab sib sau ntxhib, vim qhov curvature ntawm ntug ntawm lub raj qhib yog ze heev rau lub cev yeeb nkab tiav. , nws yuav tsis nyob rau hauv lub finishing theem thiab txawm rau high-lub zog thiab tuab-walled welded kav, lub extrusion rollers tsim misalignment thaum lub sij hawm extrusion theem.Tom qab daim ntawv zoo, ob sab ntawm ntug ntawm lub sawb yog qhov sib luag (tsis zoo V-shaped lossis rov qab V-shaped) pob qij txha.Uniform burrs yog tsim rau sab hauv thiab sab nrauv ntawm cov yeeb nkab welded, uas yog qhov zoo rau kev khawb ntawm burrs.Nyob rau tib lub sijhawm, qhov loj dua V-zoo li lub vuam lub kaum ntse ntse tuaj yeem siv rau pem hauv ntej ntawm lub tshuab vuam tshuab kom muaj txiaj ntsig zoo los tiv thaiv vuam tsis xws li cov pob grey.Thib ob, vim yog txoj kev sib txuas txuas ntxiv ntawm flange thiab qhov tshwj xeeb yob dhau kev tsim, ib feem ntawm cov sawb hlau tsuas tuaj yeem dais ib qho deformation ntawm feem ntau thaum lub sij hawm sib sau, thiab qhov kev hloov pauv tau zoo sib txuas, thiab nws tsis yooj yim rau qee yam. ib feem yuav deformed rau ntau zaus.Local thinning tshwm sim vim lub siab ntawm cov yob.Yog li ntawd, lub deformation yog ib yam, lub internal kev nyuaj siab yog me me, thiab lub internal zoo ntawm cov yeeb nkab welded yog zoo dua.
Txhawm rau ua kom tiav, FFX txoj kev siv tshuab ua ke nrog ntau qhov zoo ntawm cov txheej txheem yob txoj kev thiab yob txoj kev, thiab nws txoj kev nce qib yog qhov pom tseeb heev.ZTZG tau tsim ntau ZTF welded yeeb nkab ntau lawm kab rau ntau lub lag luam, ntawm cov uas Tangshan Wenfeng Qiyuan Steel tsim thiab tsim cov plaub-tiam FFX tsis siv neeg tsim cov kab ntau lawm, uas paub txog lub computer tswj, cim tias lub tswv yim tshiab ntawm ZTZG tau nkag mus rau theem tshiab. .PebZTF (FFX) Siv tau yooj yim tsim tshuabyuav txuas ntxiv txhim kho thiab txhim kho thaum siv.
