(1) Umshini wokwenza i-FFX ungakhiqiza amapayipi ashiselwe anezinga eliphakeme lensimbi, izindonga ezincanyana neziwugqinsi. Njengoba ukuguqulwa kobuchwepheshe bokwenza i-FFX kusekelwe ikakhulukazi emiqulu evundlile, futhi imiqulu eqondile esiteji sokwenza i-post-rough ayidingi ukusebenzisa ama-rolls angaphakathi ukulawula ukuguquguquka, isakhiwo semishini sinezici zakho kokubili ukuthamba nokuqina, futhi kulula ukuzuza amandla aphezulu kanye nokuqina okuphezulu futhi ingazinzisa Khiqiza amapayipi ashiselwe asezingeni eliphezulu ngaphezu kuka-219 mm, D/t=10 ~ 100, kanye nebanga lensimbi elifika ku-P110.
(2) Amaroli avundlile namaroli aqondile omshini wokwenza i-FFX kwabelwana ngawo ngokugcwele. Kubuchwepheshe bokwakha i-FFX, indlela yokugoba ye-involute kanye nendlela yokugoba i-roll-to-roll ihlanganiswa, ukuze amaroli avundlile namaroli aqondile kwabelwane ngawo ngokuphelele. Ngokwesibonelo, isizukulwane sesithathuUmshini wokwenza ama-roll-form we-ZTFethuthukiswe yi-ZTZG idinga kuphela ukwabelana ngeqoqo lamaroli okwakhiwa okungelula. Yehlisa izindleko zerola futhi yenza kube lula ukusetshenziswa nokuphathwa komqulu.
(3) Ukusatshalaliswa kwe-deformation kunengqondo futhi inqubo yokubumba izinzile. Esigabeni sokwenza ama-rough, indlela enkulu yokuguqula ngokuyinhloko ithatha ama-rollers avundlile, ukuze ukugoba kohlangothi lweshubhu evulekile kusondele kulelopayipi elihlanganisiwe eliqediwe, futhi ukuguqulwa kokubunjwa okuhle kuncane. Lokhu kusabalaliswa okunengqondo kokuguquguquka kwenza ukubunjwa kuzinze futhi kunqobe ububi bokwakhiwa kwamarowu. Ingozi efihliwe yokukhubazeka kwamapayipi ashiselwe ibangelwa ukusabalalisa okungenangqondo kwe-deformation.
(4) Indlela yokubumba yokugoba eqhubekayo yamukelwa ukuze kwakhiwe izimo ezingcono kakhulu zokushisela i-high-frequency welding. Ubuchwepheshe bokwakha i-FFX busebenzisa indlela yokugoba eqhubekayo futhi busebenzise ngokugcwele izici ezakhayo zemiqulu evundlile kanye namaroli aqondile ukuze kungabikho indawo efile yokuguquguquka esigabeni se-strip, futhi okubaluleke kakhulu, inqoba ngempumelelo ukuguqulwa okubangelwa ukushintsha kokuqina kwe-strip namandla. Isenzo sokutholwa kwe-elastic esikhiqizwe ngokunganele sithuthukisa ukunemba kokubumba nokuzinza. Ngemuva kokwakhiwa okungekuhle, unqenqema lwensimbi ye-strip lukhubazeke ngokuphelele ngokwepulasitiki, futhi ukugoba konqenqema lweshubhu evulekile kusondelene kakhulu neshubhu eliqediwe; i-deformation ye-fine forming incane, futhi ukuma kwe-tube evulekile ngemva kokwakhiwa okunamandla ngeke kushintshwe, okudala inzuzo enkulu ye-welding high-frequency welding. izimo ezifanele.
(5) Thuthukisa ikhwalithi yepayipi elishiselwe. Uma kuqhathaniswa nobuchwepheshe bokwenza ama-roll, ubuchwepheshe bokwenza i-FFX buphinde buthuthukise ikhwalithi yepayipi elishiselwe kulezi zici ezimbili ezilandelayo: Okokuqala, ngemva kokwakheka okuqinile, njengoba ukugoba konqenqema lweshubhu evulekile kuseduze kakhulu nomzimba wepayipi ophelile. , ngeke kube sesiteji sokuqeda futhi Ngisho nasemapayipi ashiselwe anamandla aphezulu futhi aminyene, ama-extrusion rollers akhiqiza ukungahambi kahle ngesikhathi sesiteji se-extrusion. Ngemuva kwefomu elihle, izinhlangothi ezimbili zonqenqema lomugqa ngokuyisisekelo ziyahambisana (hhayi amajoyini ezinqe ezimise okuka-V noma okuhlanekezelwe okumise okuka-V). Ama-burrs afanayo akhiwa endaweni engaphakathi nangaphandle yepayipi elishiselwe, elivumela ukukhuhla ama-burrs. Ngesikhathi esifanayo, i-angle yokushisela emise okwe-V enkudlwana ingasetshenziswa phambi komshini wokushisela we-high-frequency ukuze kuvinjwe ngempumelelo amaphutha okushisela njengamabala ampunga. Okwesibili, ngenxa yendlela eqhubekayo yokwenza i-flange kanye nomklamo oyingqayizivele we-roll pass, noma iyiphi ingxenye yengxenye yensimbi ye-strip ingathwala ukuguquguquka okukodwa kakhulu ngesikhathi sokwakheka okungahambi kahle, futhi ukuguqulwa kokuguqulwa kuxhumeke kahle, futhi akulula ukwenza okuthile. ingxenye okufanele ikhubazeke izikhathi eziningi. Ukuncipha kwendawo kwenzeka ngenxa yokucindezela kwama-roll. Ngakho-ke, i-deformation ifana, ukucindezeleka kwangaphakathi kuncane, futhi ikhwalithi yangaphakathi yepayipi ehlanganisiwe iyathuthukiswa.
Ukufingqa, ubuchwepheshe bokwenza i-FFX buhlanganisa izinzuzo eziningi zokwenza umqulu wendabuko kanye nokwakhiwa kwama-roll, futhi ukuthuthuka kwawo kusobala kakhulu. I-ZTZG ikhiqize imigqa eminingi yokukhiqiza amapayipi ashiselwe e-ZTF yamabhizinisi amaningi, phakathi kwawo i-Tangshan Wenfeng Qiyuan Steel yaklama futhi yakhiqiza umugqa wokukhiqiza ozenzakalelayo we-FFX wesizukulwane sesine, oqaphela ukulawula kwekhompyutha, okumaka ukuthi umqondo omusha we-ZTZG usungene ezinyathelweni ezintsha zesiteji. . EyethuI-ZTF(FFX) Flexible Forming technologyizoqhubeka nokuthuthuka futhi ithuthuke ngesikhathi sokusetshenziswa.
