Болты с полной и неполной резьбой: руководство по применению промышленного крепежа

2026-06-11

Ha u batla liboutu, li-screws le li-fasteners bakeng sa kaho, mechini, kapa merero ea meralo, ntlha e le 'ngoe ea bohlokoa eo hangata e hlokomolohuoang ke tlhophiso ea likhoele. A na u lokela ho khetha boutu e khoele ka botlalo kapa bolt e khoele e sa fellang (half-thread)? Karabo e ama haholo matla a kopantsoeng, katleho ea kopano, le ho tšoarella ha nako e telele. Sengoliloeng sena se hlakisa liphapang tsa bohlokoa mme se fana ka tataiso e sebetsang bakeng sa lienjineri, batsamaisi ba phumants'o ea thepa, le bahlahlobi ba projeke.

Mantsoe a bohlokoa a koahetsoeng: liboutu, li-screws, li-fasteners, liboutu tse felletseng, liboutu tsa khoele tse sa fellang, liboutu tsa hex, liboutu tsa stud, liboutu tse boima tsa hex, lithupa tse entsoeng ka likhoele, li-anti-corrosion fasteners, liboutu tse notlelitsoeng ka masenke a chesang, liboutu tse koahetsoeng ka dacromet.

1. Nako ea ho Sebelisa Liboutu Tse Feletseng

Li-bolts tse felletseng li ipabola lits'ebetsong moo ho hlokahalang ho kenella hoa khoele. Mona ke maemo a mantlha:

Likopano tsa Thin-Wall: Ha u koala lipoleiti tse tšesaane, lishiti, kapa likarolo tseo bolelele ba ho ts'oara bo leng bokhutšoane, likhoele tse felletseng li netefatsa ho kenella ho lekaneng bakeng sa torque e tiileng e tiileng.

Lihokelo tsa Tapped Hole: Ha khoele ea bolt e kena ka har'a lesoba le tlatsitsoeng (le khoele) ho e-na le ho sebelisa nate, likhoele tse felletseng li fana ka matla a phahameng a ho ts'oara ka har'a botebo bo fumanehang.

Tokiso le Clamping: Ho li-fixtures, li-jigs, le likopano tse feto-fetohang moo bolt e sebetsang e le ntho ea ho koala kapa ea ho beha maemo, likhoele tse feletseng li lumella phetoho e tsoelang pele ka bolelele bohle.

Manonyeletso a Shear-Dominant: Lihokelong moo bolt e hanelang matla a ho kuta ho fapana le meroalo e thata, likhoele tse felletseng li sebetsa hantle hobane karolo e tšekaletseng e sebetsana ka botlalo le litho tse kopaneng ka bobeli.

Li-Fasteners tsa Diameter tse Nyenyane (< M16): Bakeng sa liboutu le likurufu tse ka tlase ho bophara ba M16 le bolelele ba limilimithara tse ka tlase ho 100, khoele e felletseng ke ea kamehla ea tlhahiso mme e lumellana le lits'ebetso tse akaretsang.

2. Nako ea ho Sebelisa Li-bolts tsa Partial Thread

Li-bolts tse sa fellang ke khetho e khethiloeng ha botšepehi bo kopanetsoeng bo itšetlehile ka phetisetso e nepahetseng ea mojaro ka shank ea bolt. Maemo a bohlokoa a ts'ebeliso a kenyelletsa:

Lihokelo tsa Steel Structural: Liboutu tse boima tsa hex (ASTM A325, A490, A193 B7) tse sebelisoang meahong, marokho le litora li hloka shank e boreleli ho thibela ho kuta sefofaneng se kopaneng. Karolo ea grip e sa baleheng e fana ka sebaka se nang le bophara ba bophara bo felletseng, se bohlokoa bakeng sa likhokahano tsa slip-critical.

Bolting e Matla a Phahameng (> 100 mm Bolelele): Bakeng sa liboutu tse fetang 100 mm, khoele e sa fellang e fokotsa khatello ea maikutlo motsong oa khoele sefofaneng sa ho kuta. Shank e boreleli e aba matla a ho koala ka ho lekana ho pholletsa le litho tse kopanetsoeng.

Likopano tsa Piping le Flange: Li-flange bolts (DIN 6921, ASME B18.2.1) li sebelisa khoele e sa fellang ho boloka ho nepahala ha lihokelo tsa flange. Shank e sebetsa e le sebaka sa ho fumana sebaka, ho thibela ho sisinyeha ho lekanyelitsoeng pakeng tsa li-flanges tlas'a khatello ea baesekele.

Meroalo e Potolohang le e Matla: Mechineng e nang le vibration kapa cyclic loading, shank e sa baleheng e thibela ho roala ha mokhathala le ho fokotsa kotsi ea ho qala ho khathala ha mokhathala metsong ea khoele.

Lisebelisoa tsa Anti-Corrosion: Bakeng sa liboutu tsa hot-dip galvanized (HDG), dacromet, kapa PTFE-coated, shank e boreleli e amohela ho roala ka mokhoa o ts'oanang ho feta likarolo tse khoele, ho fana ka tšireletso e phahameng ea kutu sebakeng sa bohlokoa sa ho jara mojaro.

Thepa e boima le Morafo: Liboutu tse matla haholo (Kereiti ea 8.8, 10.9, 12.9) ho liepolli, li-crusher le li-conveyor li itšetlehile ka moralo o sa fellang oa khoele ho sebetsana le meroalo e kopantsoeng ea ho kuta le e thata libakeng tse thata.

3. Papiso e Potlakileng: Khoele e Feletseng vs

Litekanyetso	Bolt e Felletseng ea Khoele	Karolo ea Khoele Bolt
Bolelele bo Tloaelehileng	<100 mm (e tlwaelehileng)	≥ 100 mm (e tloaelehileng)
Phatlalatso ea Khoele	100% ea shank	40-60% ea boima ba 'mele
Shear Resistance	Ka tlase (karohano e fokotsehileng)	E phahameng (bophara bo felletseng ba shank)
Alignment Precision	E itekanetseng	E ntle (shank e le dowel)
Tokiso Range	Bolelele bo felletseng	Karolo e nang le khoele feela
Mokhathala Tshebetso	E itekanetseng	Betere (ha ho likhoele sebakeng sa mojaro)
Coating Uniformity	E ntle ka likhoele	E ntle ka shank e boreleli
Molemo ka ho fetisisa Bakeng sa	Clamping, likoti tse tapped, tokiso, li-fasteners tse nyane	Sebopeho, piping, dynamic mejaro, thepa e boima

. Material Grades le Surface Treatment

FUJINRUI e fana ka liboutu tse felletseng le tse sa fellang ho limaraka tse ngata tsa lisebelisoa:

Kereiti ea 4.8 / 8.8 (Q235, Q355B, Q355D carbon steel) - lits'ebetso tse tloaelehileng tsa sebopeho
Kereiti ea 10.9 / 12.9 (40Cr, 35CrMo alloy steel) - bolting e matla haholo
Stainless Steel A2/A4 (304, 316) — libaka tse senyang

Likhetho tsa anti-corrosion li kenyelletsa:

Hot-Dip Galvanized (HDG) - maemo a boima a kantle le a leoatle
Dacromet / Geomet - khanyetso e phahameng ea kutu ntle le kotsi ea hydrogen embrittlement
PTFE / Xylan - lik'hemik'hale le mocheso o phahameng oa ho hanyetsa

5. Ho Etsa Khetho e Nepahetseng

Qeto pakeng tsa khoele e feletseng le liboutu tsa khoele e sa fellang e theohela ho lintlha tse 'maloa tsa bohlokoa: mofuta o kopanetsoeng (sekoti se tapped vs. through-bolt), bolelele ba bolt (ka holimo kapa ka tlase ho 100 mm), tataiso ea mojaro (ho kuta khahlanong le tsitsipano), le maemo a tikoloho. Ha u belaela, sheba maemo a amehang (ISO, DIN, ASTM) bakeng sa ts'ebeliso ea hau e ikhethileng, kapa ikopanye le sehlopha sa rona sa boenjiniere bakeng sa tšehetso ea tekheniki.

Ho FUJINRUI, re etsa le ho romella li-fasteners tse thibelang kutu - ho kenyeletsoa lithupa tse nang le mahlakore a mabeli, liboutu tsa hex, liboutu tsa flange, linate le liwasha - ka likhoele tse felletseng le tse sa fellang. Lihlahisoa tsa rona li sebeletsa bareki ho pholletsa le Asia Boroa-bochabela, Bochabela bo Hare, Europe le Amerika makaleng a kenyeletsang kaho, petrochemical, tlhahiso ea matla le mechini e boima.
