Ngokweendlela ezahlukeneyo zokuvelisa, inokwahlulwa ibe yityhubhu eshushu eqengqelekayo, iityhubhu eziqengqelekayo ezibandayo, iityhubhu ezitsalwa ngokubanda, iityhubhu ezikhutshiweyo, njl.

1.1.Ishushu-isolweimibhobho yentsimbi engenamthungoziveliswa ngokubanzi kumatshini wokusila wemibhobho ozenzekelayo.I-tube eqinile ihlolwe kwaye ihlanjululwe kwiziphene zomhlaba, inqunyulwe ubude obufunekayo, igxininise ekupheleni kombhobho, ize ithunyelwe kwisithando somlilo sokufudumeza kunye nokubhoboza kumatshini wokubhoboza.Xa i-perforation iqhubeka ijikeleza kwaye iqhubela phambili ngexesha elifanayo, phantsi kwesenzo se-roller kunye neplagi, i-cavity yenziwa ngokuthe ngcembe ngaphakathi kwi-tube blank, ebizwa ngokuba yi-capillary tube.Kwaye emva koko ithunyelwe kwi-automated rolling mill ukuqhubeka nokuqengqeleka.Okokugqibela, ubungakanani bodonga lonke bufaniswe kumatshini wonke, kwaye ububanzi bulinganiswa ngomatshini wokulinganisa ukuhlangabezana neenkcukacha.Ukusetyenziswa kwe-tube rolling mill eqhubekayo ukuvelisa iityhubhu zentsimbi ezingenamthungo ezishushu ziqengqeleka yindlela ephucukileyo.

1.2.Ukuba ufuna ukufumana imibhobho engenamthungo enobukhulu obuncinci kunye nomgangatho ongcono, ukuqengqeleka okubandayo, umzobo obandayo okanye indibaniselwano yeendlela ezimbini kufuneka isetyenziswe.I-Cold rolling idla ngokuqhutyelwa kwi-rolling mill emibini ephezulu.Umbhobho wensimbi ugqitywe kwi-annular pass eyenziwe yi-variable cross-section circular hole groove kunye neplagi ye-tapered stationary.Umzobo obandayo udla ngokuqhutyelwa kwi-single-chain okanye i-double-chain ebandayo umatshini wokudweba we-0.5-100T.

1.3.Indlela ye-extrusion kukubeka i-tube efudumeleyo engenanto kwi-cylinder ye-extrusion evaliweyo, kwaye intonga ene-perforated kunye nentonga ye-extrusion ihamba kunye ukuze ikhuphe inxalenye ekhutshiweyo yomngxuma omncinci wokufa.Le ndlela inokuvelisa iibhobho zetsimbi ezinamadamitha amancinci.

Olu hlobo lombhobho wentsimbi lunokwahlulwa lube ziindidi ezimbini: intsimbi engenamthungo umbhobho wentsimbi kunye nentsimbi engenasici edityaniswe nombhobho wentsimbi (umbhobho womthungo).Ngokwenkqubo yokuvelisa eyahlukileyo, ingaba: i-hot-rolled, extruded, i-cold draw and cold-rolled.Ubume bunokwahlula kwiipayipi ezijikelezayo kunye nemibhobho ekhethekileyo.Imibhobho yentsimbi engqukuva isetyenziswa kakhulu, kodwa kukwakho neminye imibhobho yentsimbi emile okwezodwa enjengesikwere, uxande, isemicircular, hexagonal, equilateral triangle, kunye neoctagonal.

Kwimibhobho yentsimbi ephantsi koxinzelelo lolwelo, uvavanyo lwe-hydraulic kufuneka lwenziwe ukuze kuqinisekiswe ukuxhathisa koxinzelelo kunye nomgangatho, kwaye akukho kuvuza, ukumanzisa, okanye ukwanda phantsi koxinzelelo oluchaziweyo kufanelekile, kwaye eminye imibhobho yentsimbi nayo iphantsi kovavanyo lwe-crimping ngokwemigangatho. okanye iimfuno zomthengi.uvavanyo ukuvutha, uvavanyo flattening.

Imibhobho yentsimbi engenamthungo, ekwabizwa ngokuba yimibhobho yentsimbi engenamthungo, yenziwe ngentsimbi yentsimbi okanye imibhobho eqinileyo egqobhozelwa kwimibhobho yecapillary, ize yenziwe ngokuqengqeleka okushushu, ukuqengqeleka okubandayo, okanye ukuzoba okubandayo.Iinkcukacha zemibhobho yentsimbi engenamthungo zicaciswe ngeemilimitha zedayamitha yangaphandle * Ubukhulu bodonga
