Chubu chachitsulo chosasunthika ndi chitsulo chozungulira, chozungulira, cha makona anayi chokhala ndi gawo lobowo ndipo palibe zitsulo zozungulira.Machubu achitsulo osasunthika amapangidwa ndi ingots kapena ma billet olimba omwe amabowoleredwa m'machubu a capillary ndiyeno kutentha kukulungidwa, kuzizira kapena kuzizira.

Msokonezo zitsulo chitoliro ndi gawo dzenje, ambiri mipope ntchito kutengera madzimadzi, Mu kupinda ndi torsion mphamvu pa nthawi yomweyo, Poyerekeza zitsulo chitoliro ndi kuzungulira zitsulo ndi olimba steel.steel chitoliro kulemera ndi kuwala, ndi mtundu wa gawo chuma zitsulo, chimagwiritsidwa ntchito popanga mbali structural ndi mbali makina, monga mafuta pobowola zitsulo scaffolding zitsulo.

Msokonezo zitsulo chubu kupanga ali ndi mbiri ya zaka pafupifupi 100. The German Manismann abale poyamba anatulukira awiri mpukutu mtanda anagubuduza nkhonya mu 1885, ndiye anatulukira periodic chitoliro anagubuduza makina mu 1891, ndi Swiss RCStiefel anatulukira basi chitoliro anagubuduza makina (omwe amadziwikanso kuti pamwamba chitoliro anagubuduza nkhonya mu 1885, ndiye anatulukira periodic chitoliro anagubuduza makina mu 1891, ndi Swiss RCStiefel anatulukira basi chitoliro anagubuduza makina (wotchedwanso pamwamba chitoliro anagubuduza nkhonya) mu 190 makina opitirira mpukutuwo, monga makina 190 opitirira makina akukankhira chitoliro, anayamba kupanga makampani amakono opanda zitsulo zachitsulo.

Extrusion atolankhani ndi nthawi ozizira anagubuduza mphero bwino zosiyanasiyana ndi khalidwe la zitsulo machubu.Mu 1960s, chifukwa cha kusintha mosalekeza anagubuduza chitoliro mphero, zikamera wa atatu mphira nkhonya, makamaka kupambana kwa ntchito ya mavuto kuchepetsa makina ndi mosalekeza kuponyera billet, wakhala bwino kupanga dzuwa ndi kumatheka mpikisano wa chitoliro ndi ife msoko.

M'zaka za m'ma 1970, chitoliro chopanda msoko ndi chitoliro chowotcherera chikuyenda ndi mzake, ndipo dziko lapansi zitsulo linanena bungwe likuwonjezeka ndi oposa 5% pachaka. ndi kujambula coil.

Kugwiritsa ntchitondi gulu la machubu achitsulo opanda msoko

Ntchito: Seamless zitsulo chubu ndi mtundu wa chuma gawo zitsulo, ali ndi udindo wofunika kwambiri mu chuma cha dziko, chimagwiritsidwa ntchito mafuta, makampani mankhwala, kukatentha, siteshoni mphamvu, sitima, kupanga makina, galimoto, ndege, ndege, mphamvu, miyala, zomangamanga ndi magulu asilikali.

Gulu:

(1) Malingana ndi mawonekedwe a gawo lomwe lagawidwa kukhala: chubu chozungulira, chopangidwa ndi mawonekedwe apadera

(2) malinga ndi zinthu: mpweya zitsulo chitoliro, aloyi zitsulo chitoliro, zosapanga dzimbiri chitoliro, gulu chitoliro

(3) Malinga ndi kugwirizana akafuna: ya threaded kugwirizana chitoliro, kuwotcherera chitoliro

(4) Malinga ndi kupanga akafuna: otentha anagudubuzika (extrusion, pamwamba, kukulitsa) chitoliro, ozizira kugudubuza (kukoka) chitoliro

(5) Malinga ndi ntchito: chitoliro chowotchera, chitoliro cha mafuta, chitoliro cha payipi, chitoliro chomanga, chitoliro cha feteleza.

Seamless zitsulo chubu kupanga ndondomeko

Njira yayikulu yopanga machubu otentha opindika opanda chitsulo (njira yoyendera kwambiri):

Kukonzekera ndi kuyang'anira chitoliro cha chitoliro → kutentha kwa chitoliro → perforating → kugudubuza chitoliro → kutenthetsanso chitoliro chopanda kanthu → kukonza (kuchepetsa) m'mimba mwake → kutentha kwa kutentha → kuwongola chitoliro chomalizidwa → kutsiriza → kuyang'anira (zosawononga, thupi ndi mankhwala, kuyang'anira malo) → malo osungiramo katundu

(2) Cold anagubuduza (chojambula) chosasokonezeka zitsulo chitoliro kupanga ndondomeko

Kukonzekera billet → pickling ndi mafuta → kugudubuza ozizira (kujambula) → kutentha kutentha → kuwongola → kumaliza → kuyang'anira

The kupanga ndondomeko otaya tchati otentha-anagulung'undisa seamless zitsulo chubu ndi motere:
