Mitanda akhoza kugawidwa mu m'mimba mwake wofanana ndi kuchepetsedwa m'mimba mwake, ndi nozzle malekezero ofanana m'mimba mwakemitandandi zazikulu zofanana;Waukulu chitoliro kukula kwakuchepetsa mtandandi chimodzimodzi, pamene nthambi chitoliro kukula ndi ang'onoang'ono kuposa waukulu chitoliro kukula.Mtanda wachitsulo chosapanga dzimbiri ndi mtundu wa chitoliro choyenera chomwe chimagwiritsidwa ntchito panthambi ya chitoliro.Popanga mtanda wokhala ndi chitoliro chopanda msoko, pali njira ziwiri zomwe zimagwiritsidwa ntchito nthawi zambiri: hydraulic bulging ndi kutentha kwapakati.
A. Hydraulic bulging of hydraulic bulging cross ndi njira yopangira kukulitsa chitoliro chanthambi kudzera mumalipiro a axial azinthu zachitsulo.Njirayi ndikugwiritsa ntchito makina osindikizira apadera a hydraulic kubaya madzi mu chitoliro chopanda kanthu ndi m'mimba mwake womwewo ngati mtanda, ndikutulutsa chitolirocho chilibe kanthu kudzera mumayendedwe ophatikizika apakati pamasilinda awiri opingasa a hydraulic press.Voliyumu ya chitoliro chopanda kanthu imakhala yaying'ono pambuyo pofinyidwa, ndipo kuthamanga kwa madzi mu chitoliro chopanda kanthu kumawonjezeka ndi kuchuluka kwa chitoliro chopanda kanthu kukhala chochepa.Pamene kupanikizika kofunikira pakukulitsa kwa chitoliro cha nthambi kufikiridwa, Pansi pa mphamvu yamadzimadzi pawiri mbali ya silinda ndi chubu chopanda kanthu, zitsulo zachitsulo zimayenda pakatikati pa nkhungu ndikutuluka mu chitoliro cha nthambi.Njira ya hydraulic bulging ya mtanda imatha kupangidwa nthawi imodzi, ndikuchita bwino kwambiri;Makulidwe a khoma la chitoliro chachikulu ndi phewa la mtanda chinawonjezeka.Chifukwa chachikulu matani zida zofunika kuti hayidiroliki bulging ndondomeko ya msokonezo mtanda, pakali pano, zimagwiritsa ntchito kupanga muyezo khoma makulidwe mtanda zosakwana DN400 ku China.Zida zopangira zomwe zimagwiritsidwa ntchito ndi chitsulo chochepa cha carbon, chitsulo chochepa cha alloy ndi chitsulo chosapanga dzimbiri chokhala ndi chizolowezi chokhazikika chozizira kwambiri, kuphatikizapo zitsulo zopanda chitsulo, monga mkuwa, aluminium, titaniyamu, ndi zina zotero.
B. Hot kukanikiza kupanga mtanda ndi flatten chitoliro akusowekapo zazikulu kuposa awiri amtandapafupi ndi m'mimba mwake ya mtanda, ndi kutsegula dzenje pa gawo limene chitoliro cha nthambi chatambasulidwa;Chubu chopanda kanthu chimatenthedwa ndikuyikidwa mukufa, ndipo chojambula chojambula chitoliro cha nthambi chimayikidwa mu chubu chopanda kanthu;Pansi pa kukakamizidwa, chubu chopanda kanthu chimapanikizidwa mozungulira.Panthawi ya kuponderezedwa kwa ma radial, zitsulo zimathamangira ku chitoliro cha nthambi ndikupanga chitoliro cha nthambi pansi pa chojambula cha kufa.Njira yonseyi imapangidwa kupyolera mu kuponderezedwa kwa radial kwa chubu chopanda kanthu ndi njira yotambasula ya chitoliro cha nthambi.Mosiyana ndi hydraulic bulging spool, chitsulo cha spool chotenthetsera chotenthetsera chimalipidwa ndi kayendedwe kake ka chitoliro kopanda kanthu, choncho amatchedwanso ndondomeko yamalipiro a radial.Matani a zida zofunika popanga zinthu amachepetsedwa chifukwa cha kutentha ndi kukanikiza kwa mtanda.Mtanda wopanikizidwa ndi otenthaali ndi kusinthasintha lonse kwa zipangizo, ndi ntchito zipangizo otsika mpweya zitsulo, aloyi zitsulo ndi zitsulo zosapanga dzimbiri;Makamaka mtanda ndi lalikulu m'mimba mwake ndi wandiweyani chitoliro khoma, izi kupanga ndondomeko zambiri anatengera.
