Mandrel yog ib qho cuab yeej siv hauv kev tsim cov kav dej seamless, uas tau muab tso rau hauv cov yeeb nkab sab hauv lub cev thiab tsim ib lub voj voog nrog cov chais los tsim cov yeeb nkab. Mandrels yog yuav tsum tau rau kev nruam yeeb nkab dov, yeeb nkab oblique dov txuas ntxiv, lub sij hawm cov yeeb nkab dov, cov yeeb nkab sab saum toj, thiab txias dov thiab txias ntawm cov kav dej.
Lub Mandrel yog ib tug ntev puag ncig pas nrig uas koom nyob rau hauv lub deformation ntawm cov yeeb nkab khoom nyob rau hauv lub deformation cheeb tsam, ib yam li rau sab saum toj. Qhov txawv yog tias thaum oblique dov, Mandrel txav axially hauv cov khoom siv yeeb nkab thaum nws tig; Thaum lub sij hawm longitudinal dov (nruam lub raj dov, lub caij nplooj ntoos hlav dov, lub raj sab saum toj), Mandrel tsis tig tab sis kuj txav axially nrog lub raj.
Nyob rau hauv lub floating Mandrel thiab txwv cov lus tsa suab Mandrel nruam yeeb nkab dov tshuab (saib nruam yeeb nkab dov tshuab rau cov yeeb nkab dov), Mandrel yog ib qho cuab yeej tseem ceeb. Ntxiv nrog rau kev ua los ntawm cov khoom siv muaj zog thiab siab hnav tsis kam, lawv kuj xav tau cov khoom zoo, xws li kev sib tsoo thiab kev kho cua sov tom qab tig. Lub floating Mandrel yog ntev heev (txog 30m) thiab hnyav (txog 12t). Qhov ntev ntawm qhov txwv Mandrel yog luv me ntsis, tab sis nws yuav tsum muaj cov khoom zoo dua. Lub Mandrel siv rau sab saum toj yeeb nkab yuav tsum muaj peev xwm tiv taus lub zog thawb loj. Lub Mandrel ntawm lub caij nplooj ntoos hlav dov tshuab muaj lub sijhawm cua sov ntev thaum lub sijhawm ua haujlwm. Lub Mandrels ntawm kab pheeb ces kaum dov thiab stretching tshuab suav nrog nro Mandrels, ntab Mandrels, txwv Mandrels, thiab retraction Mandrels.
Lub nro Mandrel yog Mandrel uas txav axially ntawm qhov ceev tshaj qhov axial ceev ntawm cov yeeb nkab thaum lub sijhawm ua haujlwm (saib cov yeeb nkab kab pheeb ces kaum rolling extension), thiab exerts nro ntawm lub puab nto ntawm cov yeeb nkab. Kev tawm ntawm hom Mandrel yog Mandrel uas txav mus rau qhov sib txawv ntawm qhov kev taw qhia axial ntawm lub raj, thiab raug rau tom qab nro. Cov kev xav tau rau Mandrel ntawm kab pheeb ces kaum dov thiab ncab tshuab yog qis dua li cov longitudinal dov thiab stretching tshuab.
Mandrel txwv tsis pub muaj ntau yam kev siv tseem ceeb hauv cov txheej txheem ntawm cov yeeb nkab dov, feem ntau yog tshwm sim hauv cov hauv qab no:
l Txhim kho phab ntsa thickness raug:
Qhov txwv tsis pub txav Mandrel dov zeb ua kom qhov tseeb ntawm cov yeeb nkab phab ntsa tuab los ntawm kev tswj qhov ceev ntawm Mandrel. Qhov ceev ntawm Mandrel yuav tsum siab tshaj qhov nrawm nrawm ntawm thawj thav duab thiab qis dua qhov nrawm nrawm ntawm thawj thav duab, thiaj li ua kom muaj kev ceev ceev tas mus li thoob plaws hauv cov txheej txheem dov, zam qhov tsis sib xws ntawm cov hlau ntws, thiab txo qhov tshwm sim. ntawm "Bamboo knots".
l Txhim kho qhov zoo ntawm cov kav dej steel:
Vim qhov kev sib txheeb ze ntawm Mandrel thiab sab hauv ntawm cov yeeb nkab steel, qhov txwv tsis pub txav Mandrel dov zeb yog qhov tsim nyog rau kev txuas ntxiv ntawm cov hlau, txo qhov deformation ntawm sab hauv, thiab txhim kho qhov tseeb ntawm sab hauv thiab sab nrauv thiab qhov ntev ntawm cov hlau. cev steel.
l Shorten cov txheej txheem ntws:
Piv nrog rau cov floating Mandrel dov zeb, qhov txwv tsis pub txav Mandrel dov zeb tshem tawm lub tshuab stripping, ua kom cov txheej txheem ntws, ua rau qhov kawg dov kub ntawm cov kav hlau, thiab txuag lub zog.
