Thaum ua tiav kev tsim kho, ntau tus lej sib txawv tau siv. Ceev yog siv dav. Hauv khw muag khoom, cov neeg siv khoom yuav tuaj yeem pom ntau yam ntawm cov khoom siv zoo li no. Hnub no peb yuav tham txog cov txiv ntseej nruab nrog lub ntsej muag tshwj xeeb uas tiv thaiv kom tsis txhob xoob.

Kev piav qhia thiab lub hom phiaj

Cov fasteners no yog cov me me hexagonal lossis cov square. Muaj qhov nyob hauv lawv qhov chaw nruab nrab. Dhau li, sab hauv ntawm lub qhov no muaj qhov tshwj xeeb uas tsim los rau kis lub zog siv lub cuab yeej.

Kev tsim ntawm cov txiv ntoo uas tau tso cai tso cai rau ntu kom nruj nreem rau saum npoo.

Cov cuab yeej zoo li no feem ntau hu ua flange . Thiab tseem muaj cov qauv nrog cov ntsiab lus tiaj tus. Cov qauv no feem ntau muag hauv cov khoom 100, 200 lossis 1000 daim hauv ib pob.

Ceev nrog qhov tshwj xeeb thais kom tiv thaiv xoob tau suav tias yog cov khoom siv txhim khu kev qha ntau dua.

Lawv cov qauv tsim yuav tsis tshem tawm cov ntsia hlau thaum lub sijhawm ua haujlwm ntev, muab kev sib txuas zoo thiab muaj zog ntawm cov khoom ib leeg rau ib leeg. Cov cuab yeej no tau siv los txuas cov khoom sib txuas (ntsia hlau, ntsia liaj qhov rooj, txuas), cov tais kab hlau.

Lawv yog dab tsi?

Ceev nrog cov ntawv tshwj xeeb kom tiv thaiv xoob tuaj yeem sib txawv nyob ntawm cov khoom siv thiab kev tsim khoom siv tshuab

Stainless hlau ntsiab . Cov khoom siv no muaj qib siab ntawm lub zog, kev ntseeg tau thiab ua tau ntev. Notched steel fasteners kuj tseem tshwj xeeb tiv tshav kub, cov khoom tuaj yeem tiv taus kub hloov pauv sai. Cov qauv hlau tsis huv feem ntau siv thaum txhim kho cov qauv uas yuav nyob hauv huab cua qhib, vim tias lawv tiv taus ib puag ncig zoo.

Stainless hlau yog suav tias yog cov khoom siv zoo ib puag ncig. Nws tsis raug rau kev tsim cov xeb thiab cov quav hniav txawm tias tom qab siv ntev.

Xws li lub hauv paus hlau tuaj yeem yog ntau yam . Yog li, cov hlau austenitic yog qhov sib txawv, lawv tau ua nrog qhov sib ntxiv me me ntawm chromium thiab npib tsib xee, cov hlau duplex, lawv tau ua nrog tib qho ntxiv, suav nrog nitrogen. Ferritic, martensitic hom stainless hlau kuj tseem tuaj yeem sib txawv.

Galvanized galvanized kho qauv . Electroplating yog ua los ntawm kev thov ntau yam tshuaj lom neeg thiab hlau txheej rau cov khoom siv. Hauv galvanic galvanizing, txheej txheej zinc yog ua los ntawm cov hlau hauv qhov hnyav ntawm cov electrolyte. Hauv cov txheej txheem ntawm electrolysis, zinc pib yaj, tom qab uas nws cov ions tso rau ntawm qhov khoom.

Galvanized hlau yog tshwj xeeb tiv taus rau tsim ntawm txheej corrosive.

Fasteners ua los ntawm cov hlau nrog cov txheej txheej, txawm tias nyob hauv cov huab cua siab thiab hloov pauv kub sai sai, tuaj yeem nyob ntev, muab kev sib txuas muaj zog thiab ntseeg tau ntawm cov khoom.

Cov pa roj carbon tsawg . Cov khoom siv no yog cov tawv tawv uas tsis muaj cov khoom sib xyaw ua ke. Cov hlau no tau ua nrog tshwj xeeb tsis huv thiab ntxiv cov pa roj carbon. Cov pa roj carbon tsawg muaj cov manganese thiab silicon.

Cov hlau no yog mos, nws tsis nquag siv los tsim cov fasteners.

Nws tsis muaj qib siab ntawm lub zog. Cov hlau yog tus yam ntxwv uas tsis muaj zog, nws yog qhov rhiab heev rau cov neeg ua haujlwm laus, vim tias nrog kev rov ua dua nws yuav hnov qhov kev nyuaj siab . Feem ntau, thaum ua cov txiv ntseej los ntawm cov pa roj carbon tsawg, tshwj xeeb tawv siv los ua kom lawv muaj zog thiab ntseeg tau ntau li ntau tau.

Qee zaum, hauv kev tsim cov fasteners zoo li no, tooj liab lossis tooj dag tau ntxiv rau hauv lub hauv paus hlau. Qee hom txiv ntseej nrog lub ntsej muag tshwj xeeb yog tsim los ntawm lub hauv paus magnesium thiab duralumin.

Cov txiv ntoo kuj tuaj yeem sib txawv los ntawm ib leeg nyob ntawm cov chav kawm raug. Cov pab pawg hauv qab no yog qhov txawv:

• chav kawm A (pawg no hais txog cov khoom lag luam ntawm qhov tseeb ntau ntxiv);
• chav kawm B (txiv ntoo ntawm qhov tseeb);
• chav kawm C (cov qauv ua kom ntxaws ntxaws).

Cov qauv uas nyob hauv chav A tau ua tiav . Yuav tsum tsis muaj qhov tsis xws luag lossis lwm yam tsis xws luag ntawm lawv qhov chaw. Qhov ntau yam thib ob kuj tseem ua tiav, tab sis qee qhov tsis xwm yeem tuaj yeem tso cai. Fasteners teej tug mus rau ntau yam tom kawg tuaj yeem tsim nrog qhov tsis raug, lawv tsis ua tib zoo ua tib zoo ua thawj ob hom.

Ceev kuj txawv nyob ntawm lawv lub zog.

Muaj xya chav kawm muaj zog tag nrho: 4, 5, 6, 8, 9, 10, 12.

Cov npe no qhia 1/100 ntawm lub zog tensile ntawm cov ntsia hlau lossis ntsia liaj qhov rooj uas cov txiv ntoo txuas nrog.

Qhov ntev thiab qhov hnyav

Txhua qhov ntev tau qhia rau ntawm pob khoom khawm. Kev tsim qauv yooj yim yog hais txog txoj kab taub. Cov qauv feem ntau yog M6, M8, M10 . Tab sis kuj hauv khw muag khoom kho vajtse koj tuaj yeem pom cov khoom M16 thiab M48.

Qhov hnyav ntawm cov fasteners no kuj tseem tuaj yeem hais qhia ntawm pob khoom . Lawv txhua tus kuj hnyav dua. Cov qauv nrog txoj kab uas hla me tshaj tuaj yeem muaj qhov hnyav ntawm 0, 32; 0.81; 1,23g ib. Cov nrawm nrawm tuaj yeem hnyav hauv thaj tsam ntawm 11-64 grams.

Cov Lus Qhia Xaiv

Ua ntej yuav khoom xws li cov ntsia hlau, koj yuav tsum xyuam xim rau qee qhov nuances.

Nco ntsoov saib qhov loj ntawm cov txiv ntoo. Hauv qhov no, qhov kev xaiv yuav nyob ntawm seb qhov loj me ntawm cov khoom sib txuas.

Thiab tseem xav txog cov khoom siv los ntawm cov txiv ntoo ua. Qhov muaj zog tshaj plaws thiab ruaj khov tshaj plaws yog cov qauv ua los ntawm cov hlau kho . Qhov saum npoo ntawm cov txiv ntoo thiab cov ntawv yuav tsum tau ua tib zoo hauv av, yuav tsum tsis muaj qhov tsis xws ntawm nws, txwv tsis pub qhov no yuav cuam tshuam rau kev ntseeg tau ntawm kev txuas.

Cov qauv zoo yuav tsum muaj cov cim tshwj xeeb.

Nws yuav suav nrog 4 tus lej thiab ntawv Latin . Kev txiav txim siab tso cai rau koj txiav txim siab hom xov (sab nraud lossis sab hauv) thiab tus lej ntawm qhov khoob hauv nws. Thaum xaiv, nws yog ib qho tseem ceeb uas yuav tau saib lub zog thiab chav kawm raug.

Cov khoom lag luam zoo yuav tsum tau tsim khoom raws li lub xeev tus qauv (GOST 50592). Cov khoom siv txawv teb chaws raug tsim raws li DIN (6923), ASA thiab lwm yam.
