(1) Muchina wekugadzira weFFX unogona kugadzira mapaipi akasungwa ane giredhi resimbi repamusoro, madziro akatetepa uye akakora. Sezvo deformation yeFFX yekugadzira tekinoroji inonyanya kuve yakavakirwa payakachinjika rolls, uye iyo yakatwasuka rolls mumashure-yakaomarara yekugadzira nhanho haidi kushandisa emukati rolls kudzora deformation, chimiro chemidziyo chine hunhu hwekupfava uye kusimba, uye iyo. iri nyore kuwana simba repamusoro uye kusimba kwepamusoro uye inokwanisa kudzikamisa Gadzira mapaipi akaiswa emhando yepamusoro pamusoro pe219 mm, D/t=10 ~ 100, uye giredhi resimbi kusvika P110.
(2) Mipumburu yakatwasuka uye yakatwasuka mitsetse yeFFX yekugadzira muchina inogovaniswa zvizere. MuFFX yekugadzira tekinoroji, iyo involute roll chimiro uye roll-to-roll yekupeta nzira inosanganiswa, kuitira kuti yakachinjika mitsetse uye yakatwasuka rolls inogona kugovaniswa zvizere. Somuenzaniso, chizvarwa chechitatuZTF roll-forming muchinayakagadziridzwa neZTZG inongoda kugovera seti yemapumburu ekuumbwa kwakashata. Iyo inoderedza mutengo weiyo roller uye inorerutsa kushandiswa uye manejimendi yemupumburu.
(3) Kugoverwa kwe deformation kunonzwisisika uye nzira yekuumba yakagadzikana. Muchikamu chakaoma chekugadzira, nzira huru yekushandura inonyanya kutora mabheji akakomberedzwa, kuitira kuti kupeta kweparutivi rwechubhu yakazaruka kuswedera pedyo neyoyo yakapedzwa welded pombi, uye deformation yekugadzira yakanaka idiki. Uku kugoverwa kunonzwisisika kwe deformation kunoita kuti kuumbwa kugadzikane uye kukurira zvipingamupinyi zvekugadzira mutsara roll. Ngozi yakavanzwa ye welded pombi kuremara kunokonzerwa nekusanzwisisika kugovera kwe deformation.
(4) Iyo inoenderera mberi yekukotama yekugadzira nzira inogamuchirwa kugadzira iyo yakanakisa mamiriro epamusoro-frequency welding. FFX yekugadzira tekinoroji inotora iyo inoenderera mberi yekupeta kuumba nzira uye inoshandisa zvizere iyo inoteedzana yekugadzira hunhu hweakachinjika ma rolls uye akatwasuka rolls kuitira kuti pasave nenzvimbo yakafa yedeformation muchikamu chemutsetse, uye zvakanyanya kukosha, inokunda zvinobudirira deformation yakakonzerwa ne kuchinja kwekukora uye simba. Iyo isina kukwana yakagadzirwa elastic recovery phenomenon inovandudza kuumba kurongeka uye kugadzikana. Mushure mekugadzira hutsinye, mupendero wesimbi inoputika yakakanganiswa zvachose mupurasitiki, uye curvature yemupendero wechubhu yakashama iri pedyo zvakanyanya neiyo yehubhu yakapedzwa; iyo deformation yekugadzira yakanaka idiki, uye chimiro chechubhu yakavhurika mushure mekuita rough haizoshandurwe, izvo zvinogadzira mukana wakakura wepamusoro-frequency welding. optimal conditions.
(5) Kuvandudza kunaka kwepombi yakasungwa. Kuenzaniswa neiyo roll yekugadzira tekinoroji, iyo FFX yekugadzira tekinoroji inonatsiridzawo kunaka kwepombi yakasungwa muzvikamu zviviri zvinotevera: Chekutanga, mushure mekuumbwa kwakashata, sezvo kukombama kwemupendero wechubhu yakashama kuri padyo nemuviri wepombi wakapera. , hazvizove padanho rekupedzisa uye Kunyange kune yakakwirira-simba uye gobvu-walled welded pombi, extrusion rollers inobudisa misalignment panguva extrusion danho. Mushure mechimiro chakanaka, mativi maviri emupendero wemutsara anonyanya kufanana (kwete akanaka V-yakaita V kana inverted V-shaped) majoini. Uniform burrs inoumbwa mukati uye kunze kwekunze kwepombi yakashongedzwa, iyo inobatsira kukweshwa kweburrs. Panguva imwecheteyo, hombe yeV-yakaita welding angle inogona kushandiswa pamberi pe-high-frequency welding muchina kudzivirira zvinobudirira kukanganisa kwewelding senge grey mavara. Chechipiri, nekuda kweinoenderera mberi yekugadzira flange nzira uye yakasarudzika roll pass dhizaini, chero chikamu cheiyo strip simbi chikamu chinogona kutakura chete deformation panguva yekuumbwa kwakashata, uye shanduko yekuchinja yakanyatsobatanidzwa, uye hazvisi nyore kune imwe. chikamu chekuremara kwenguva dzakawanda. Kutetepa kwenzvimbo kunoitika nekuda kwekumanikidzwa kwemapumburu. Nokudaro, deformation iyunifomu, kushushikana kwemukati kuduku, uye kunaka kwemukati we welded pombi inovandudzwa.
Kupfupisa, FFX yekugadzira tekinoroji inosanganisa akawanda mabhenefiti echinyakare roll kuumba uye roll kuumba, uye kufambira mberi kwayo kuri pachena. ZTZG yakagadzira akawanda ZTF akaiswa pombi yekugadzira mitsara yemabhizinesi mazhinji, pakati peiyo Tangshan Wenfeng Qiyuan Steel yakagadzira uye yakagadzira yechina-chizvarwa FFX otomatiki yekugadzira mutsara wekugadzira, uyo unoona kutonga kwekombuta, zvichimaka kuti iyo itsva pfungwa yeZTZG yapinda nhanho nyowani. . YeduZTF(FFX) Flexible Kugadzira tekinorojiicharamba ichivandudza nekuvandudza panguva yekushandiswa.
