Uma ufuna noma yimuphi umshini ozosebenza ngekhoyili, akungabazeki ukuthi udinga i-uncoiler noma i-uncoiler.
Ukutshala imali emishinini emikhulu kuwumsebenzi odinga ukuthi ucabangele izinto eziningi nemisebenzi. Ingabe udinga umshini ongahlangabezana nezidingo zamanje zokukhiqiza, noma ufuna ukutshala ezicini zesizukulwane esilandelayo? Lena imibuzo abanikazi bezitolo abahlale bezibuza yona uma bethenga umshini wokwenza ama-roll. Kodwa-ke, ucwaningo lwama-uncoiler alutholanga ukunakwa okuncane.
Uma ufuna noma yimuphi umshini ozosebenza ngekhoyili, ngakho-ke akungabazeki ukuthi udinga i-uncoiler (noma ngezinye izikhathi ebizwa ngokuthi i-uncoiler). Kungakhathaliseki ukuthi une-roll forming, yokugxiviza noma umugqa wokukhiqiza wokusika, udinga i-uncoiler ukuze ukhulule ikhoyili isinyathelo esilandelayo; ayikho ngempela enye indlela yokwenza. Ukuqinisekisa ukuthi i-decoiler ihlangabezana ne-workshop yakho kanye nezidingo zephrojekthi kubalulekile ekugcineni ukwakheka komshini wokwenza umqulu, ngoba ngaphandle kwezinto ezibonakalayo, umshini ngeke usebenze.
Eminyakeni engu-30 edlule, imboni ishintshe kakhulu, kodwa i-uncoiler ihlale iklanywe ngokuhambisana nemininingwane yemboni yekhoyili yensimbi. Eminyakeni engamashumi amathathu edlule, i-diameter yangaphandle evamile (OD) yamakhoyili ensimbi yayingama-intshi angu-48. Njengoba izinga lokwenziwa ngokwezifiso komshini liya ngokuya likhuphuka, futhi iphrojekthi idinga izinketho ezahlukene, ukuguquguquka kwekhoyili yensimbi ngamasentimitha angu-60, bese kuba ngamasentimitha angu-72. Namuhla, abakhiqizi basebenzisa amakhoyili amakhulu kunamayintshi angu-84. in. Ikhoyili. Ngakho-ke, i-decoiler kufanele ilungiswe ukuze ivumelane ne-diameter yangaphandle eguqukayo njalo yekhoyili.
Ama-uncoiler asetshenziswa kakhulu embonini yokugoqa. Imishini yanamuhla yokwenza umqulu inezici nemisebenzi eminingi kuneyandulelayo. Isibonelo, eminyakeni engu-30 edlule, isivinini sokusebenza somshini wokugaywa sasingamafidi angama-50 ngomzuzu (FPM). Manje sebengakwazi ukugijima kufikela ku-500 FPM. Lolu shintsho ekukhiqizweni kokwenza umqulu luphinde lwathuthukisa amandla kanye nohlu oluyisisekelo lwezinketho ze-decoiler. Akwanele ukukhetha noma iyiphi i-decoiler evamile. Izinto eziningi nemisebenzi edinga ukucatshangelwa ukuze kuqinisekiswe ukuthi izidingo zomhlangano wokusebenzela ziyahlangatshezwa.
Umkhiqizi we-decoiler unikeza izinketho ezahlukahlukene zokuqinisekisa ukuthi inqubo yokwenza umqulu ingenziwa kahle. I-decoiler yanamuhla inesisindo esingamaphawundi ayi-1,000. Ngaphezu kwamaphawundi angu-60,000. Lapho ukhetha i-decoiler, sicela ukhumbule imininingwane elandelayo:
Kufanele futhi ucabangele uhlobo lwephrojekthi ozobe usebenza kuyo kanye nezinto ozozisebenzisa.
Konke kuncike ekutheni yini ofuna ukuyiqhuba emshinini wokugaywa, okuhlanganisa ukuthi ikhoyili iyisimboli, i-galvanized noma i-stainless steel. Lezi zici zizonquma ukuthi yiziphi izici ze-decoiler ozidingayo.
Isibonelo, i-decoiler evamile iyi-decoiler ene-end-end, kodwa ukuba ne-decoiler eneziphetho ezimbili kunganciphisa isikhathi sokulinda sokuphatha impahla. Ngezinsimbi zokuphotha ezimbili, opharetha angalayisha ikhoyili yesibili emshinini futhi ayicubungule noma nini lapho kudingeka. Lokhu kuyasiza kakhulu lapho osebenza ngaso sonke isikhathi efuna ukushintsha ikhoyili.
Abakhiqizi ngokuvamile abakuboni ukusebenza kwe-decoiler baze babone ukuthi i-decoiler ingenza imisebenzi yokushintsha eyisithupha kuya kweyisishiyagalombili noma ngaphezulu ngosuku. Ngemva kokulungisa ikhoyili yesibili emshinini nokulinda umshini, asikho isidingo sokulayisha ikhoyili yokuqala nge-forklift noma i-crane ngokushesha. I-decoiler idlala indima ebalulekile endaweni eyenza umqulu, ikakhulukazi ekukhiqizeni ngobuningi, lapho umshini ungase udinge amahora ayisishiyagalombili amashifu ukuze wakhe izingxenye.
Lapho utshala imali ku-decoiler, kubalulekile ukuqonda ukucaciswa kwamanje nezici. Kodwa-ke, kubalulekile futhi ukucabangela ukusetshenziswa kwesikhathi esizayo komshini nokuthi yiziphi izinhlelo zesikhathi esizayo ezingase zibe sezigayweni. Lezi zonke izici ezidinga ukucatshangelwa ngokufanele, futhi zisiza ngempela ukucacisa i-decoiler efanele.
Imoto yekhoyili isiza ukulayisha ikhoyili ku-mandrel ngaphandle kokulinda i-crane noma i-forklift ukuthi iqede.
Ukukhetha i-mandrel enkulu kusho ukuthi ungagijima ikhoyili encane emshinini. Ngakho-ke, uma ukhetha 24 amayintshi. Spindle, ungenza noma yimiphi eminye imisebenzi. Uma ufuna ukugxumela kumayintshi angu-36. Inketho, lapho-ke udinga ukutshala imali ku-decoiler enkulu. Kubalulekile ukubheka amathuba esikhathini esizayo.
Njengoba amakhoyili ekhula futhi esinda, ukuphepha kuyinkinga enkulu endaweni yokusebenzela. I-decoiler inezingxenye ezinkulu, ezihamba ngokushesha, ngakho-ke opharetha kufanele baqeqeshwe ekusebenzeni komshini kanye nezilungiselelo ezifanele.
Namuhla, amakhoyili angasukela ku-33 kuya ku-250 kilograms per square inch, futhi ama-uncoiler ashintshiwe ukuze ahlangabezane nezidingo zamandla okukhiqiza amakhoyili. Amakhoyili asindayo adala izinselele zokuphepha ezinkulu, ikakhulukazi lapho usika amabhande. Umshini uhlanganisa ingalo yokucindezela kanye ne-buffer roller ukuze kuqinisekiswe ukuthi umqulu ukhululiwe kuphela njengoba kudingeka. Umshini ungaphinda ufake idrayivu yokuphakelwa kwephepha kanye nesisekelo sokushintsha ohlangothini ukuze usize phakathi nendawo iwebhu ngenqubo elandelayo.
Njengoba isisindo ikhoyili ukwanda, kuba nzima ngokwengeziwe ukuze ngesandla ukwandisa mandrel. Lapho indawo yokusebenzela isusa opharetha emshinini wokusula imyisa kwezinye izindawo zeshabhu ngenxa yezizathu zokuphepha, ngokuvamile kudingeka ama-spindle anwetshwe ngamanzi kanye namandla okuzungezisa. I-shock absorber ingangezwa ukuze kuncishiswe ukuhlukumeza kokujikeleza kwe-decoiler.
Kuye ngenqubo nesivinini, ezinye izici zokuphepha zingadingeka. Lezi zimpawu zihlanganisa isibambi sekhoyili sangaphandle esivimbela ukuba ikhoyili ingawi, isistimu yokuqapha i-coil outer diameter kanye ne-RPM, kanye nama-braking systems ahlukile njengamabhuleki apholile amanzi ukuze amapayipi ahamba ngesivinini esikhulu. Lezi zibaluleke kakhulu futhi zisiza ukuqinisekisa ukuthi lapho inqubo yokugoqa ima, i-decoiler nayo iyama.
Uma usebenza ngezinto ezinemibala eminingi, ungasebenzisa i-decoiler ekhethekile enikeza ama-mandrels amahlanu, okusho ukuthi ungabeka amakhoyili amahlanu ahlukene emshinini ngesikhathi esisodwa. Umsebenzisi angenza amakhulu ombala owodwa bese eshintshela kowesibili ngaphandle kokuchitha isikhathi ethula ikhoyili futhi eshintsha.
Esinye isici semoto yekhoyili ukuthi iyasiza ukulayisha ikhoyili ku-mandrel. Lokhu kuqinisekisa ukuthi u-opharetha akudingeki alinde i-crane noma i-forklift ukuze ilayishe.
Kubalulekile ukuchitha isikhathi ucwaninga izinketho ezahlukene ezitholakalayo ze-decoiler. Nge-mandrel eguquguqukayo yokufaka amakhoyili amadayamitha ahlukene angaphakathi, kanye nezinhlobonhlobo zosayizi ongakhetha kuzo ikhoyili engemuva, udinga ukucabangela izici eziningi ukuze uthole ukulingana okufanele. Ukufaka kuhlu izicaciso zamanje nezingenzeka kuzokusiza ukuthi unqume izici ezidingekayo.
Imishini yokwenza ama-roll, njenganoma yimuphi omunye umshini, yenza imali kuphela uma isebenza. Ukukhetha i-decoiler efanele yezidingo zesitolo sakho zamanje nezesikhathi esizayo kuzosiza umshini wakho wokwenza ama-roll usebenze ngokuphumelelayo nangokuphepha.

Njengoba manje sesine-CASL, sidinga ukuqinisekisa ukuthi uyavuma yini ukuthola izibuyekezo nge-imeyili. Ingabe lokho kulungile?
