Ubunzima bodonga olungalinganiyo lwetyhubhu engenamthungo (SMLS) bubonakaliswa ikakhulu kwisenzeko sobunzima bodonga olungalinganiyo lwemilo ejikelezayo, ubukhulu bodonga olungalinganiyo lomgca othe ngqo, kunye neendonga ezityebileyo nezincinci entloko nasemsila. Impembelelo yokulungelelaniswa kwenkqubo eqhubekayo yeetyhubhu ezingenamthungo yinto ebalulekileyo ekhokelela kubunzima bodonga olungalinganiyo lwemibhobho egqityiweyo. Ngokukodwa:
1. Ubukhulu bodonga olujikelezayo lwetyhubhu engenamthungo abulingani

Izizathu zezi: 1) Ubunzima bodonga lombhobho wensimbi ongenamthungo abulingani ngenxa yezizathu zohlengahlengiso ezifana nomgca ochanekileyo weziko lokubhoboza umatshini wokubhoboza, i-angle inclination ye-rolls ezimbini, okanye inani elincinci lokunciphisa phambi kweplagi, kwaye isasazwe ngokubanzi kwimilo ejikelezayo kunye nobude bonke bombhobho wentsimbi. .
2) Ngexesha lenkqubo yokuqengqeleka, i-roller centering ivulwa kwangethuba kakhulu, i-centering rollers ayilungiswanga kakuhle, kwaye ubukhulu bodonga bungalingani ngenxa yokushukuma kwentonga ye-ejector, esasazwa ngokubanzi kwimilo ejikelezayo kulo lonke ubude. wombhobho wentsimbi.

Umlinganiselo:
I-1) Lungisa umgca weziko lokubhoboza umatshini wokubhoboza ukwenzela ukuba i-angles inclination of the rolls two rolls ilingane, kwaye ulungelelanise i-rolling mill ngokweeparitha ezinikwe kwitafile ejikelezayo.

2) Kwimeko yesibini, lungisa ixesha lokuvula i-roller centering ngokwesantya sokuphuma kwi-tube ye-capillary, kwaye ungavuli i-roller centering ngokukhawuleza ngexesha lenkqubo yokukhusela intonga ye-ejector ukuba ingagungqi, okubangela udonga olungalinganiyo. ubukhulu bombhobho wentsimbi ongenamthungo. Iqondo lokuvula i-centering roller kufuneka lilungiswe ngokufanelekileyo ngokuhambelana nokutshintshwa kobubanzi be-capillary, kwaye ukubetha kwe-capillary kufuneka kuthathelwe ingqalelo.
2. Ubukhulu bodonga olunomgca wombhobho ongenamthungo abulingani

Unobangela:
1) Uhlengahlengiso ukuphakama mandrel pre-ukugqobhoza isali ayifanelekanga. Xa i-mandrel igqobhoza ngaphambili, iqhagamshelana ne-capillary kwelinye icala, ibangela ukuba iqondo lokushisa le-capillary lihle ngokukhawuleza kumphezulu woqhagamshelwano, okubangela ukungalingani kodonga lombhobho wentsimbi engenamthungo okanye i-concave defect.
I-2) I-gap phakathi kwee-rolling rolls eziqhubekayo zincinci okanye zikhulu kakhulu.
3) Ukuphambuka komgca ophakathi we-rolling mill.
I-4) Ukunciphisa ukungalingani kwe-rack eyodwa kunye nephindwe kabini kuya kubangela ukuphambuka komgca we-symmetrical wepayipi yensimbi ibe yi-ultra-thin (i-ultra-thick) kwicala le-rack enye kunye ne-ultra-thick (ultra-thin) kwicala. yeerack ezimbini.
I-5) I-abutment yokhuseleko iphukile, kwaye umehluko phakathi kwezithuba zangaphakathi kunye nangaphandle ze-roll zinkulu, eziza kubangela ukuphambuka kwe-asymmetric yomgca ochanekileyo wombhobho wensimbi.
I-6) Ukulungelelaniswa okungafanelekanga kokuhamba ngokuqhubekayo, ukupakisha insimbi kunye nokudweba ukudweba kuya kubangela ubuninzi bodonga olungalinganiyo kumgca ochanekileyo.

Umlinganiselo:
1) Lungisa ukuphakama mandrel pre-ukugqobhoza isali ukuze kuqinisekiswe ukugxilwa kwe mandrel kunye capillary.
I-2) Xa utshintsha uhlobo lokupasa kunye nokuchazwa kwe-rolling, i-gap ye-roll kufuneka ilinganiswe ukuze kugcinwe i-gap yangempela ye-roll ehambelana netafile.
3) Ukulungelelanisa umgca we-rolling centre kunye nesixhobo sokujonga i-optical centering, kwaye umgca ophakathi we-rolling mill kufuneka ulungiswe ngexesha lokuguqulwa konyaka.
4) Ngexesha elifanelekileyo buyisela isakhelo ngodaka lokhuseleko oluphukileyo, ukulinganisa izithuba zangaphakathi kunye nezangaphandle ze-roll eziqhubekayo, kwaye uzitshintshe ngexesha ukuba kukho ingxaki.
I-5) Ngexesha lokuqhubela phambili, umzobo wensimbi kunye nokupakisha kufuneka kugwenywe.

3. Ubukhulu bodonga lwentloko yetyhubhu engenamthungo kunye nomsila azilingani
Unobangela:
I-1) I-slope yokusika kunye ne-curvature ye-front end ye-tube engenanto inkulu kakhulu, kwaye i-centing hole ye-tube blank ayichanekanga, eya kubangela lula ukuba ubukhulu bodonga lwentloko yombhobho yensimbi ingalingani.
2) Xa ubhobhoza, i-coefficient ye-elongation inkulu kakhulu, isantya somqulu siphezulu kakhulu, kwaye ukuqengqeleka akuzinzile.
I-3) Ukuphoswa kwentsimbi engazinzanga ngumbhobho kunokubangela lula ubuninzi bodonga olungalinganiyo ekupheleni kombhobho we-capillary.

Umlinganiselo:
I-1) Khangela umgangatho wetyhubhu engenanto ukukhusela isiphelo sangaphambili setyhubhu engenanto ekunqumleni ukuthambekela kunye nokunciphisa okukhulu, kwaye umgodi ophakathi kufuneka ulungiswe xa utshintsha uhlobo lokupasa okanye ukugqithisa.
2) Sebenzisa isantya esisezantsi sokubhoboza ukuze uqinisekise ukuzinza kokuqengqeleka kunye nokulingana kodonga lwe-capillary. Xa isantya somqulu silungiswa, ipleyiti yesikhokelo ehambelanayo nayo ihlengahlengiswa ngokufanelekileyo.
I-3) Nika ingqalelo kwisimo sokusetyenziswa kweplati yesikhokelo kunye nokwandisa ukuhlolwa kweebholiti zesikhokelo, ukunciphisa uluhlu lokuhamba kweplate yesikhokelo ngexesha lentsimbi, kwaye uqinisekise ukuzinza kwentsimbi.
