Kupanga Cold Roll

Cold Roll Forming (Cold Roll Forming) ndi njira yopangira yomwe imagudubuza zitsulo zazitsulo mosalekeza kudzera m'mipukutu yopangidwa motsatizana kuti ipange ma profailo amitundu ina.

(1) Gawo lopanga movutikira limatenga kuphatikiza kwa mipukutu yogawana ndi ma rolls m'malo. Zogulitsa zikasinthidwa, mipukutu ya maimidwe ena safunika kusinthidwa, zomwe zimatha kusunga nkhokwe zina.
(2) Mapepala ophatikizika a masikono athyathyathya, gawo lopanga movutikira ndi maimidwe asanu ndi limodzi, gulu loyimirira loyimirira limapangidwa mopanda malire, kuchuluka kwa mipukutuyo ndi yaying'ono, ndipo kulemera kwa mipukutu ya makina opangira masikono kumachepetsedwa ndi kuposa 1/3, ndipo kapangidwe ka zida ndi kocheperako.
(3) Mipukutu yopindika yopindika ndiyosavuta, yosavuta kupanga ndi kukonzanso, ndipo kuchuluka kwakugwiritsanso ntchito mpukutu ndikwambiri.
(4) Kupangako kumakhala kokhazikika, mphero yogubuduza imakhala yogwira ntchito kwambiri popanga machubu okhala ndi mipanda yopyapyala ndi machubu otchingidwa kumbuyo, ndipo mawonekedwe ake ndi osiyanasiyana.

Cold roll kupanga ndi njira yopulumutsira zinthu, yopulumutsa mphamvu komanso yothandiza komanso njira yatsopano yopangira zitsulo. Kugwiritsa ntchito ndondomekoyi, osati kutulutsa mankhwala apamwamba gawo zitsulo, komanso akhoza kufupikitsa mkombero mankhwala chitukuko, bwino kupanga, ndipo motero kusintha msika mpikisano wa mabizinesi.
Pazaka makumi asanu zapitazi, kupanga mipukutu yozizira kwasintha kukhala njira yabwino kwambiri yopangira zitsulo. 35% ~ 45% ya chitsulo chachitsulo chogubuduza ku North America chimasinthidwa kukhala zinthu zopindika mozizira, zomwe zimaposa zitsulo zomwe zimagwiritsidwa ntchito pamagalimoto.

M'zaka zaposachedwa, zida zachitsulo zoziziritsa kuzizira zakhala zikugwiritsidwa ntchito kwambiri ngati magawo ofunikira m'magawo ambiri monga zomangamanga, kupanga magalimoto, kupanga zombo, mafakitale amagetsi ndi kupanga makina. Zogulitsa zake zimachokera ku njanji zowongolera wamba, zitseko ndi mazenera ndi zigawo zina zamapangidwe kupita kuzinthu zina zapadera zopangidwira zolinga zapadera, zokhala ndi mitundu yosiyanasiyana. Ntchito ya gawo pa kulemera kwa unit ya chitsulo chozizira bwino ndi yabwino kuposa yazitsulo zotentha zotentha, ndipo imakhala ndi mapeto apamwamba komanso olondola. Choncho, m'malo mwa zitsulo zotentha ndi zitsulo zozizira zimatha kukwaniritsa zotsatira ziwiri zopulumutsa zitsulo ndi mphamvu, choncho anthu amakonda zitsulo zozizira. Kukula kwazitsulo zopindika kwapatsidwa chidwi chachikulu. Ndi chikhumbo chosalekeza cha ogwiritsa ntchito mitundu yosiyanasiyana, kufotokozera ndi khalidwe lazitsulo zozizira zomwe zimalimbikitsa chitukuko chofulumira cha teknoloji yopangidwa ndi kuzizira.
