1. Txiv ntseej yog dab tsi?
Lub txiv ntoo yog ib tug poj niam threaded fastener uas ua ke nrog bolts thiab studs rau clamp workpieces ua ke. Nws hloov torque mus rau hauv clamping quab yuam kom xauv cov rooj sib txoos. Tshwj xeeb los tiv thaiv- cov txiv ntseej xoob tuaj yeem tiv taus kev vibration, poob siab thiab kub hloov pauv yam tsis tau xoob.
Core functions:
- Ruaj ntseg mechanical Cheebtsam rau kev sib dhos
- Sib npaug sib npaug kom tsis txhob muaj kev puas tsuaj
- Cia yooj yim disassembly rau kev kho
- Tiv thaiv kom tsis txhob xoob nyob rau hauv dynamic ua hauj lwm loads
2. Hom txiv ntseej ntau yam & kev siv
Hex noob(DIN934 / ISO4032)
Cov txheej txheem dav siv ntau tshaj plaws nrog rau rau sab tiaj tus rau kev teeb tsa wrench. Nyias hex ceev haum rau qhov chaw nqaim; hnyav hex txiv ntoo dais hnyav.
Siv cov ntaub ntawv: General machinery, steel thav duab, rooj tog thiab cia racks.
Nylon Insert Lock Nut (Nylon Nut)
Ua-hauv nylon nplhaib tsim kev sib txhuam ntxiv kom tsis txhob xoob hauv kev co.
Kev txwv: Ua haujlwm kub qis dua 120 degree, tsis tuaj yeem rov siv tau ntau zaus.
Siv cov ntaub ntawv: Auto qhov chaw, motors, hluav taws xob txee, conveyors.
Hex Flange Txiv ntseej
Integrated flange hloov cov tshuab ntxhua khaub ncaws; serrated flanges tiv thaiv slipping. Cov cheeb tsam loj dua tiv thaiv cov ntawv hlau nyias.
Siv cov ntaub ntawv: Auto ncua kev kawm ntawv, pipeline fittings, sheet hlau los ua ke.
Lwm yam Nrov Styles
- Square txiv ntseej: Xauv hauv U-channel steel rau racking thiab elevator
- Wing Nut: Tes-tightened tsis muaj cuab yeej rau disassembly ceev
- Tsev fuabtais Slotted txiv ntoo: Kho nrog cotter pins rau log hubs thiab bearing shafts
- Acorn Cap Nut: Npog cov xov xov rau kev nyab xeeb thiab kho kom zoo nkauj
3. Txiv ntseej khoom sib piv
Carbon Steel (Qib 4.8 / 8.8 / 10.9 / 12.9)
Thaum tshav kub kub-kho alloy steel muab siab tensile zog rau hnyav loads. Nto tiav suav nrog zinc plating, kub-dip galvanized thiab Ruspert txheej rau xeb.
Qhov zoo tshaj plaws rau: Kev tsim kho steel qauv, tshuab hnyav, tsheb thav duab.
Stainless hlau 304 (A2-70) & 316 (A4-80)
- 304: Basic tiv thaiv-corrosion rau sab nraum zoov, zaub mov thiab dej tshiab ib puag ncig
- 316: Molybdenum ntxiv los tiv thaiv ntsev tsuag thiab tshuaj chloride, zoo tagnrho rau cov ntug dej hiav txwv & dej hiav txwv
Lus Cim: Stainless hlau threads yooj yim gall; siv los tiv thaiv- txeeb cov roj nplua nyeem thaum lub sijhawm teeb tsa.
4. Lub zog qib & xov txoj cai
- Carbon steel: qib siab dua txhais tau tias muaj peev xwm thauj khoom muaj zog. Ib txwm phim cov txiv ntseej qib nrog bolt qib (10.9 bolt xav tau Qib 10 txiv ntoo).
- Stainless hlau: A2-70 rau 304, A4-80 rau 316.
- Cov xov ntxhib: Tus qauv rau feem ntau muaj xwm txheej, zoo dua shear kuj.
- Cov xov zoo: Zoo sealing thiab tiv thaiv - xoob kev ua tau zoo rau precision nyias- phab ntsa.
5. Cov qauv tseem ceeb thoob ntiaj teb
- DIN (Tebchaws Europe): DIN934 hex txiv ntoo, DIN985 nyloc xauv txiv ntoo
- ISO: Kev sib koom ua ke thoob ntiaj teb kev ntsuas tus qauv (sib npaug rau DIN series)
- ANSI: Ntiv - loj txiv ntseej rau North American lag luam
- GB: Cov txheej txheem ntau lawm rau export fasteners
6. Daim ntawv txheeb xyuas ceev
1. Load xav tau: Xaiv qhov sib piv lub zog qib
2. Ib puag ncig ua haujlwm: Xaiv cov khoom & tiv thaiv- xeb txheej
3. Kev vibration theem: Standard txiv ntoo rau static loads, xauv txiv ntseej rau vibrating khoom
4. Qhov chaw nruab: Txheem / nyias / flange hex txiv ntseej
5. Kev txwv kub: Tsis txhob nyloc ceev rau siab - cov khoom kub
7. Cov lus nug uas nquag nug
Q1: 304 vs 316 stainless hlau ceev?
316 tiv taus dej hiav txwv thiab ntsev huab cua, zoo meej rau cov chaw ua haujlwm ntawm ntug dej hiav txwv thiab tshuaj lom neeg. 304 yog tus nqi- siv tau rau cov khoom siv sab nraum zoov thiab zaub mov.
Q2: Kuv puas tuaj yeem rov siv cov nylon xauv ceev?
Tsis pom zoo rau hnyav - cov khoom siv dynamic. Lub nplhaib nylon poob kev sib txhuam tom qab rov nruj dua.
Q3: Vim li cas cov txiv ntseej stainless tuav thaum zawm?
Xov galling tshwm sim vim kev sib txhuam. Kev nrawm nrawm nrog tiv thaiv - txeeb muab tshuaj txhuam tuaj yeem daws qhov teeb meem no.
Yog tias koj xav tau cov txiv ntseej tshwj xeeb nrog ntau qhov tshwj xeeb, kho qhov chaw lossis OEM cim, thov hu rau peb kom tau txais cov lus hais dawb. Peb muab ntau yam ntawm fasteners rau manufacturers thoob ntiaj teb.
