Uchungechunge Lokusebenza Lomshini Wokwenza I-ERW Tube - Ingxenye 2: Ukuqondanisa Okunembile Nokulungiswa Kokusebenza Okufanelekile

Esitolimendeni esedlule, sihlanganise izinyathelo ezibalulekile zokuqaqa, ukuhlola, ukuphakamisa, nokwenza izinguquko ezimbi emshinini wakho omusha wokwenza amashubhu we-ERW. Manje, siqhubekela enqubweni ebalulekile yokuqondanisa okunembile nokulungiswa, isici esibalulekile ekuqinisekiseni ukukhiqizwa kweshubhu eliphezulu kanye nokusebenza kahle.

Ukuqonda Ukulungiswa: Umgomo Wokuqondanisa Okuphelele

Ukulungiswa, kulo mongo, kubhekisela ekucushweni kahle kwenqubo yokwenza umqulu ukuze kuqinisekiswe ukuthi ishubhu elingenalutho lihamba kahle futhi lizinzile emshinini, ekugcineni likhiqize amashubhu ahlangabezana nezimfuneko ezidingekayo. Uma umshini ungakha amashubhu ngale ndlela, khona-ke kungathiwa "ukulungiswa" kube yimpumelelo. Ukulungiswa okwengeziwe ngesikhathi sokwenziwa kokukhiqiza okuvamile kuvame ukubhekwa kangcono njengokuthi “ukuxazulula inkinga” lapho izinto zingasebenzi njengoba bekulindelekile.

Ukulungiswa kweyunithi ye-weld tube kungahlukaniswa ngezinyathelo ezilandelayo:

I. Ukulungiselela Kungukhiye: Ukuhlola Amaroli Nokuhlola Isimo Somshini

Ngaphambi kokungena enqubweni yokulungisa, ukulungiselela ngokucophelela kubalulekile:

• Ukuhlolwa kwekhwalithi ye-Roll:Gxila ekubunjweni kwe-roll eyenza i-groove. Sebenzisa isifanekiso ukuze uqinisekise ukuthi umumo womqulu ngamunye uhambisana nezidingo zedizayini. Lahla noma yimaphi amaroli angahlangabezani namazinga. Futhi, qaphela ububanzi besisekelo somqulu. Lokhu kuqinisekisa ukuthi wonke amaroli azungeza ngokuvumelanisa. Amapheya afanayo emiqulu adinga ukulingana ngosayizi nokuma.
• Ukuhlola Isimo Somshini:Qinisekisa ukuthi umshini usebenza ngendlela efanele. Lokhu kungafinyezwa kanje:
  • Izimbazo ezivundlile kufanele zibe izinga.
  • Izimbazo eziqondile kufanele ziqonde.
  • Ukuma kweroli kufanele kuzinzile.
  • Izingxenye zokushelela kufanele zihambe ngokukhululeka nangokushelela.
  • Ukulungisa kufanele kube lula ukwenza.

  Uma umshini ungahlangabezani nalezi zidingo, yenza ukulungiswa ukuze uwubuyisele emandleni awo okusebenza ayisisekelo. Kubalulekile ukulungisa noma yini ebonisa ukuziphatha okulandelayo: ukungakwazi ukulungisa, ukungazinzi ngemva kokulungiswa, noma ukuma kokukhukhuleka.

II. Ukuqondanisa Okunembile: Isisekelo Sokukhiqizwa Kweshubhu Yekhwalithi

1. Ukuqondanisa kweGroove

Ukuqondanisa i-Groove kuyisinyathelo sokuqala senqubo yokulungisa.

• Khetha intambo yensimbi engu-0.5mm. Yisebenzise namarola okuphakelayo omshini wokwenza amarola aqondisayo omshini wokulinganisa njengobude besisekelo.
• Nquma isikhungo somugqa wokugoqa. Vikela intambo yensimbi futhi uyimise njengomugqa oqonde ngokuphelele futhi omile.
• Qinisekisa ukuthi ubude bocingo lwensimbi buphakeme kancane kunobubanzi obungaphansi berola eliyisicaba (2mm noma ngaphezulu). Ngaleyo ndlela izogwema ukuthintana ne-arc ye-groove engathinta ukulinganisa nokuma okufanele. Le ntambo yensimbi izoba ulayini wereferensi wokuqondanisa kwe-groove.
• 

2. Ukuqondanisa Kwerola Elivundlile

Kunezindlela ezimbili zokuqondanisa amaroli avundlile:

• Indlela yoku-1: Sebenzisa i-motor yokulungisa ukunxephezela umehluko wokujiya phakathi kwama-groove roller ahlukahlukene. Kodwa-ke, uma ukunemba kokucubungula izingxenye kungahlangabezani nezimfuneko, amaphutha anqwabelene angenzeka kalula ngemva kokuhlanganiswa, athinte ngokuqondile umphumela wokuqondanisa womumo wokugoqa.
• Indlela yesi-2: Sebenzisa inati lokukhiya ukuze ulungise indawo yama-roller ku-shaft, ukuze isikhungo se-groove ye-roller ngayinye sihambisane nomugqa ophakathi. Isifanekiso esikhethekile sisetshenziselwa ukuhlola ukuma kwesikhungo se-groove. Lapho uhlola, faka isifanekiso ku-groove eqondaniswe, bese uphakamisa kancane ingxenye engaphezulu. Lapho ucingo lwensimbi lungawela kahle emseleni ophakathi kwesifanekiso, kubonisa ukuthi indawo emaphakathi ye-groove ilungile, ngaphandle kwalokho, ukulungiswa kokunyakaza kwe-axial kuyadingeka. Lena indlela elula yokuqondanisa.

Ukuqondanisa ama-roller aphezulu kusebenzisa ama-roller angezansi njengereferensi. Ngemva kokubala ibanga eliphakathi nendawo phakathi kwama-roller ayisicaba angaphezulu naphansi, lungisa ama-roller angaphezulu abe endaweni evundlile. Ifomula yokubala ibanga lesikhungo se-axial imi kanje:

• Vula Ukubalwa Kwebanga le-Groove Axial Center:H = (Owehlayo + Owehlisayo) ÷ 2 + t – a
• Ukubalwa Kwebanga Lesikhungo Se-Groove Axial:H = Owehlayo + 2R – aWhere:
  • I-Dlower = Ububanzi obuphansi be-roller engezansi (mm)
  • I-Dupper = I-diameter yangaphandle ye-roller ephezulu (mm)
  • t = Ugqinsi lweshubhu elingenalutho (mm)
  • R = I-Radius yegroove yokulinganisa (mm)
  • a = Ukunciphisa i-coefficient (0.1-0.5)

  Inani le-coefficient a lincike ikakhulukazi ebukhulu beshubhu elingenalutho, inani lokunciphisa ububanzi bangaphandle beshubhu, usayizi kanye nokucaciswa, kanye nesimo sangempela esifana nobubanzi be-shaft kanye nokuguqulwa okunwebeka kwe-shaft. Nokho, ukugoqa okubandayo akukwazi ukwenzeka emshinini wokwakha. Ukuthi inani lokunciphisa elikhethiwe linengqondo yini lingalinganiswa futhi lihlolwe ngezimpawu zokuhlehlisa zocingo lwe-fuse. Uma wenza isampula, qala uqale iyunithi bese uyivula ngesivinini esinensa kakhulu, bese ugoba intambo ye-fuse ubukhulu bayo bungaphezudlwana kogqinsi lweshubhu elingenalutho ukuze lifane nomsele, bese uphakela kancane kancane emshinini wokugaya ukuze uthole ukuhlehla kwentambo ye-fuse.

Ngemva kokuba i-roller engenhla isilinganisiwe, indawo emaphakathi ye-axial yerola engaphezulu ye-groove evulekile ingase futhi ibekwe phakathi ne-gauge yepulaki yesitayela sesifanekiso ukuze kuhlolwe ukuthi ingabe igebe phakathi kwezinhlangothi ezimbili ze-roller groove engezansi kanye ne-roller groove iyafana. Uma zifana, indawo ye-axial ye-roller engenhla ingakhiywa. Sebenzisa indlela yokuthinta yemisele evaliwe ukuze uhlole ukuthi imifantu engaphezulu nangaphansi iyahlangana yini.

3. Ukuqondanisa kwe-Roller eqondile

Ukuqondanisa kwerola eqondile kungahlukaniswa ngezinyathelo ezintathu:

• Okokuqala, thola igebe lokuvula leqembu ngalinye lama-roller aqondile, okungukuthi, ibanga lesikhungo se-axial phakathi kwama-roller amabili aqondile;
• Bese, thola indawo emaphakathi yeqembu ngalinye lamarola aqondile;
• Ekugcineni, lungisa ukuphakama kwama-roller aqondile.

Igebe lokuvula le-roller eqondile kufanele lisekelwe ububanzi bokuvula ukuguquguquka ngesikhathi sokuklanywa komumo we-roll, bese incipha cishe ngo-5mm. Uma inani le-shrinkage likhulu kakhulu, lizosheshisa ukuguga konqenqema olungenhla lomumo we-roller omile futhi lwandise umthwalo emishinini.

Isikhungo serola esime mpo kufanele siqondaniswe ngesikhathi esifanayo nerola evundlile ukuze kuqinisekiswe ukuthi izindawo ezimaphakathi zamarola avundlile naqondile zisemgqeni ofanayo omaphakathi. Ngemuva kokuthi kutholwe umugqa omaphakathi wegroove eqondile yerola, intambo yensimbi ingehliswa ifike endaweni yobubanzi obuphansi begroove evundlile, futhi ukuphakama kwerola eqondile kungaqalwa. Ubude berola eqondile kufanele busekelwe ekuphakameni konqenqema oluphansi lwegroove eqondile ehambisana nobude bentambo yensimbi. Ukuphakama kwama-rollers ambalwa okuqala aqondile ngaphambi kokwakhiwa kufanele kunqunywe ngokuvumelana nemingcele yenqubo yenani lokusika indandatho ye-roller ephansi.

4. Okunye Ukuqondanisa Kwe-Groove

Indlela yokuqondanisa yezinye izimo zokugoqa ingabhekisela kumgomo wokuqondanisa wamarola asicaba namarola aqondile. Ukuthi nje indawo yobubanzi obuphansi berola engezansi yerola eqondisayo kufanele ibe phezulu kancane kunomugqa wereferensi ngo-0.5～2 mm (kuye ngokuthi ububanzi nobukhulu bodonga lweshubhu elikhiqiziwe). Irola esekela i-burr kufanele ibe phezulu ngo-0.5mm kunolayini wereferensi ukwenza amandla azinze lapho uhlela amabhara angaphandle futhi uvimbele ukuplana ekugxumeni.
