Ho Utloisisa Bohlokoa ba Tokiso e Ntle

Kamora ho hlophisoa ha pele le ho tsamaisana ha li-groove, ho lokisa hantle se seng le se seng sa liteishene tsa ho etsa moqolo ho tla netefatsa sebopeho se nepahetseng le se tsitsitseng sa tube. E 'ngoe le e 'ngoe ea litulo tsa bohlokoa e tla sebetsanoa ho fana ka ts'ebetso e nepahetseng le ho nepahala.

Mokhoa oa ho Fetola

I. Horizontal Roll Stand Liphetoho

1. Boemo bo Otlolohileng:Fetola sebaka se rapaletseng sa roll ho phahamisa bohareng ba shaft e ka tlase ho boemo bo hlokahalang.
2. Matla a Emeng:Sebelisa enjene e lokisang ho theola shaft e kaholimo, ho beha lekhalo lipakeng tsa lirolara tse holimo le tse tlase ho latela setšoantšo sa groove.
3. Axial Clearance:Fetola sebaka sa axial ho netefatsa hore litsi tsa li-groove tsa lirolara tse holimo le tse tlase li hokahane ka kotloloho ho netefatsa ho nepahala ha tube.

II. Liphetoho tsa Moqolo o otlolohileng

Fetola sebaka se bohareng pakeng tsa lirolara tse peli tse otlolohileng ka ho phethola screw e etellang pele ho ts'oana le profil ea moqolo oa pasa ea hajoale. Haeba ho na le skew le rolling centerline, e tlameha ho fetoloa hape ho e beha bohareng ba mohala.

III. Tataiso Roll Stand Liphetoho

1. Boemo bo nepahetseng:Fetola sebaka sa moqolo oa tataiso sebakeng se loketseng, 'me u lokise bohareng ba lirolara tse tataisang hore li tsamaisane le li-rolling centerline.
2. Axial Adjustment:Fetola boemo ba axial ba moqolo oa moqolo.
3. Opening Angle Adjustment:Fetola boemo ba moqolo oa tataiso ema holim'a worktable ho fetola angle bula, e leng bebofatsa tjheseletsa.

VI. Liphetoho tse otlolohileng

1. Phetoho ea Phokotso:Fetola palo ea phokotso ho lumellana le bophara ba tube e phethiloeng.
2. Maemo a Fetoleha:Fetola maemo a lirolara tse rapameng le tse otlolohileng e le hore bohareng ba li-grooves tsa bona ha e le hantle li tsamaisane le "rolling centerline".

Ho Lokisetsa Matha a Teko

Liphetoho tse ka holimo li lokela ho etsoa pele tlhahlobo e etsoa. Litokiso tse nepahetseng li tla etsoa in-situ, kahoo mehato e kaholimo e ka nkuoa e le qalo e thata. Ho e lokisa ho qala ka mohala o lekantsoeng hantle le o boreleli. Seo se bolela hore ho ba hlokolosi nakong ea ho lokisa le ho kenya ho tla lefa meputso.
