4. Setšoantšo sa likarolo tsa Bolt
5. Boitsebiso ba Bolt
6. Matshwao, Mephato ya Tshebetso, jj.
1. Matšoao: Bakeng sa liboutu le li-screw tse mahlakore a tšeletseng (bophara ba khoele> 5mm), matšoao a lokela ho etsoa ka holim'a hlooho ho sebelisoa litlhaku tse phahamisitsoeng kapa tse khutliselitsoeng morao, kapa lehlakoreng la hlooho ho sebelisoa litlhaku tse khutlisitsoeng. Sena se kenyelletsa limaraka tsa tšebetso le matšoao a moetsi. Bakeng sa tšepe ea carbon: Khoutu ea ho tšoaea kereiti ea matla e entsoe ka lihlopha tse peli tsa linomoro tse arohaneng ka “·”. Moelelo oa karolo ea nomoro ka pele ho “·” khoutung ea ho tšoaea e bontša matla a matla a lebitso. Mohlala, "4" sehlopheng sa 4.8 e bonts'a matla a ho tiea a 400N/mm2, kapa 1/100 ea seo. Moelelo oa karolo ea nomoro ka mor'a "·" khoutung ea ho tšoaea e bonts'a karo-karolelano ea chai-to-tensile, e leng karo-karolelano ea ntlha ea chai ea lebitso kapa matla a tlhahiso ea lebitso ho matla a ho tsitsa a lebitso. Ka mohlala, ntlha ea lihlahisoa tsa sehlahisoa sa 4.8 ke 320N / mm2. Matšoao a matla a sehlahisoa sa tšepe ea tšepe a entsoe ka likarolo tse peli tse arohaneng ka "-". Letšoao le ka pele ho "-" khoutu ea ho tšoaea le bontša thepa, e kang A2, A4, joalo-joalo Letšoao ka mor'a "-" le bontša matla, joalo ka A2-70.
2). Kereiti: Bakeng sa tšepe ea carbon, metric bolt mechanical performance grades e ka aroloa ka lihlopha tse 10 tsa tshebetso: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, le 12.9. Tšepe e sa hloekang e arotsoe ka lihlopha tse tharo: 60, 70, 80 (austenitic); 50, 70, 80, 110 (martensitic); 45, 60 (ferritic).
7. Kalafo ea Bokaholimo
Kalafo ea holim'a metsi haholo-holo ke ho eketsa ho hanyetsa ho bola, 'me ba bang ba boetse ba nahana ka' mala, kahoo haholo-holo ke bakeng sa lihlahisoa tsa carbon steel, tseo ka kakaretso li hlokang phekolo ea holim'a metsi. Liphekolo tse tloaelehileng tsa holim'a metsi li kenyelletsa ho soeufala, ho galvanizing, ho roala ka koporo, ho roala ha nickel, ho roala ka chrome, ho pata silevera, khauta ea khauta, dacromet, hot-dip galvanizing, joalo-joalo; ho na le mefuta e mengata ea galvanizing, e kang zinki e putsoa le e tšoeu, zinki e putsoa, zinki e tšoeu, zinki e mosehla, zinki e ntšo, zinki e tala, joalo-joalo, 'me li boetse li arotsoe ka mefuta e sa tsotelleng tikoloho le e se nang botsoalle. Sehlopha se seng le se seng se na le botenya bo bongata ba ho roala ho fihlela litlhoko tse fapaneng tsa tlhahlobo ea letsoai.
Kakaretso ea Lihlahisoa tsa Likarolo tsa Boemo ba Likoloi
1). Kakaretso ea likarolo tsa maemo a likoloi
Likarolo tse tloaelehileng tsa likoloi li na le mefuta e fapaneng mme li sebelisoa tlhahisong e ikhethileng ea likarolo le likarolo tse fapaneng tsa likoloi, hammoho le ho hokahanya le ho bokana ha litsamaiso tse fapaneng tse fapaneng ho theha koloi eohle. Boleng ba likarolo tse tloaelehileng bo na le phello ea bohlokoa ho boleng ba kakaretso le ts'ebetso ea lisebelisoa tsa mochini, 'me baetsi ba likoloi hangata ba na le mekhoa e tiileng ea tlhahlobo le litekanyetso tsa setifikeiti bakeng sa litsamaiso tsa phepelo ea li-fasteners. Boholo bo boholo ba mmaraka ba indasteri ea likoloi bo fana ka sebaka se pharaletseng sa nts'etsopele bakeng sa lihlahisoa tse tloaelehileng tsa likarolo tsa likoloi. Ho ea ka lipalo-palo, koloi e bobebe kapa koloi ea baeti e hloka hoo e ka bang 50kg (likotoana tse ka bang 5,000) tsa likarolo tse tloaelehileng, ha koloi ea khoebo e mahareng kapa e boima e hloka hoo e ka bang 90kg (likotoana tse ka bang 5,710).
2). Likarolo tsa Likarolo tsa Boemo ba Likoloi
Moetsi e mong le e mong ea ka sehloohong oa enjene indastering ea likoloi o sebelisa "Melao e Tloaelehileng ea Lipalo tsa Lihlahisoa tsa Likoloi" (QC/T 326-2013) ho theha lintlha tsa lipalo tsa likarolo tse tloaelehileng tsa khoebo, 'me litaba li lula li tšoana leha ho na le phapang.
Likarolo tse tloaelehileng tsa likoloi hangata li na le likarolo tse 7, ka tatellano:
- Karolo ea 1: Khoutu ea likarolo tse tloaelehileng tsa likoloi;
- Karolo ea 2: Khoutu e fapaneng;
- Karolo ea 3: Fetola khoutu (ho ikhethela);
- Karolo ea 4: Khoutu ea litlhaloso tsa boholo;
- Karolo ea 5: Ts'ebetso ea mochini kapa khoutu ea thepa;
- Karolo ea 6: Khoutu ea phekolo ea holim'a metsi;
- Karolo ea 7: Khoutu ea maemo (ka boikhethelo).
Mohlala: Q150B1250TF61 e emela bolt ea hlooho ea hexagonal e nang le lintlha tsa khoele ea M12, bolelele ba bolt ea 50mm, boemo ba ts'ebetso ea 10.9, le seaparo se se nang electrolytic sa zinc (silevera-gray). Mokhoa oa ho etsa setšoantšo ke o latelang:
