Kev tshuaj xyuas thiab kho cov tooj liab ntxhua khaub ncaws yog cov ncauj lus tseem ceeb hauv kev ua haujlwm niaj hnub no. Cov ntsiab lus ntawm cov txheej ntawm cov tshuab ntxhua khaub ncaws 10x14x1 mm thiab lwm qhov loj me yog qhov tseem ceeb. Nws yog qhov muaj txiaj ntsig zoo kom paub yuav ua li cas txhawm rau txhawm rau txhawm rau ntxiv rau, nrog rau yam uas yuav tsum tau ua ua ntej rau GOST uas twb muaj lawm.

Kev piav qhia thiab lub hom phiaj

Kev siv ntau yam kev sib khi tau siv los txhim kho kev ntseeg tau thiab ruaj khov ntawm cov ntsia hlau txuas. Kev xaiv cov khoom siv rau lub tshuab ntxhua khaub ncaws yog txiav txim siab los ntawm qhov cuam tshuam qhov kev txuas yuav ua li cas. Lub tshuab tooj liab yog qhov zoo tshaj plaws nyob qhov twg muaj qhov kub thiab txias nyob hauv qhov xwm txheej tsis tu ncua lossis tsis tu ncua . Yog li ntawd, nws tau siv dav hauv kev lag luam engineering thaum sib dhos cov txheej txheem tsim los rau kev kub siab. Ua ntej tshaj plaws, peb tab tom tham txog roj thiab khoom siv hydraulic.

Qhov ntxim nyiam ntawm tooj liab ntxhua khaub ncaws rau thaub qab ntawm cov saw hlau thiab rau lub tsheb ntsaws ntsaws kuj tseem cuam tshuam nrog:

• tshuaj lom neeg tsis kam ntawm lawv cov khoom hauv ib puag ncig txhoj puab heev;
• zoo heev corrosion kuj;
• kev khaws cia ntawm kev ua haujlwm sib khi raws li qhov ua kom sov nce ntxiv, nrog rau kev hloov pauv tseem ceeb hauv cov txheej txheem cua sov;
• kev co tsis kam;
• lub zog thiab ruaj khov ntawm cov khoom siv hauv qab qhov tseem ceeb.

Cov fasteners no tseem tuaj yeem siv hauv cov tshuab tsheb, txhua ntu uas tau ua kom sov tas li, thaum tseem tab tom ntub. Qhov kev lav phib xaub siab no txhais tau tias cov tshuab ntxhua khaub ncaws ua tau raws li qhov xav tau muaj zog. Ua raws li GOST tau teev tseg rau hom khoom tshwj xeeb yog qhov tseem ceeb . Cov ntaub ntawv ua raws cai tuaj yeem nrhiav pom ntawm cov ntawv ntim thawj ntawm cov khoom siv thiab ntawm daim ntawv pov thawj zoo nrog. Kev ua tiav ntawm cov khoom xav tau feem ntau yog nyob ntawm tus yam ntxwv ntawm cov khoom noj.

Txoj hauv kev ntxhua khaub ncaws zoo li tau piav qhia meej hauv GOST 18123-82. Raws li tus txheej txheem no, yuav tsum tsis muaj qhov sib txawv los ntawm qhov ua kom du ntawm qhov chaw. Tsis pub burrs lossis tawg. Cov tshuab ntxhua khaub ncaws uas muaj cov tsos mob ntawm kev xeb lossis nrog cov hlau drips kuj tsis ua raws li cov qauv. Roughness ntau dua 3, 2 microns tseem tso cai tsis lees txais cov khoom lag luam.

Cov txheej txheem tswj cuam tshuam, ua ntej tshaj plaws, kuaj pom qhov muag . Yog tias tsim nyog, kev kawm raug yog ua los ntawm lub iav tsom iav. Roughness tau ntsuas los ntawm cov qauv ntsuas raws li GOST 9378-75 lossis siv cov cuab yeej ntsuas tshwj xeeb.

Qee zaum cov tshuab ntxhua khaub ncaws tooj liab tau pleev xim nrog txheej txheej hmoov tshwj xeeb kom muab xeb ntxiv tiv thaiv. Cov txheej no tau tswj hwm los ntawm GOST 9.302-79.

Nta ntawm ntau lawm

Cov txheej txheem, cov txheej txheem tooj liab tuaj yeem sawv cev rau kev sib sau ua ke, qee zaum cov duab plaub. Lawv tau qhia meej qhov txawv los ntawm lawv pawg neeg raug. Txuj Kev Ntsuas Qib - B, Ua Kom Tau Raws Li Qib - A . Cov thev naus laus zis siv tam sim no cuam tshuam nrog kev tsim cov tooj liab ntxhua khaub ncaws los ntawm kev txiav lossis txuas ntxiv los ntawm cov hlau. Lub hauv paus pib tuaj yeem yog ob daim ntawv thiab daim hlau.

Cov khoom ntim yuav tsum tau muab txhuam kom huv thiab tom qab ntawd qhia meej. Nws tsis tuaj yeem muaj khawb thiab khawb. Yuav tsum tsis muaj qhov nicks uas cuam tshuam rau kev ua haujlwm ntawm lub tshuab ntxhua khaub ncaws. Lub luag haujlwm ntawm kev pleev xim yog txhawm rau txhawm rau txhim kho cov yas ntawm cov hlau, vim qhov kev hloov pauv ntawm ib feem nrog qhov ntsuas kub poob qis.

Cov qib tooj liab M1, M2, M3 feem ntau yog siv rau kev tsim cov tshuab ntxhua khaub ncaws . Ntawm lawv, M3 yog qhov kev xaiv zoo tshaj plaws. Muaj tseeb, cov hlau tuaj yeem hloov pauv nyob ntawm qhov sib txawv ntawm kev ua haujlwm yav tom ntej.

Hauv qee kis, siv cov qib tooj liab txawv, muaj cov pa thiab phosphorus tsawg.

Kev tshem tawm yog nqa ncaj qha hauv kev tsim khoom, tab sis yog tias cov khoom raug khaws cia ntev, koj yuav tsum rov ua cov txheej txheem.

Cov khoom qib

Kev kos npe rau ntawm lub tshuab ntxhua tooj liab ib txwm qhia tias muaj hmoov txheej. P29 cov khoom hauv chav kawm yog galvanized thiab passivated. P34 cim txhais tau tias cov khoom tsuas yog passivated. Hauv cov xwm txheej uas tus txheej txheem muab rau ntau dua ib chav kawm raug, nws lub npe raug muab tso rau thaum pib ntawm lub hom. Cov muaj pes tsawg leeg ntawm cov npav suav nrog:

• hom kev ua tiav;
• seem ntawm xov;
• ib feem tuab;
• tshuaj lom neeg hom;
• raws txoj cai;
• tuab ntawm txheej txheej siv;
• siv tus qauv.

Muaj cov txheej txheem yooj yim xws li:

GOST 10450-78 (cov khoom lag luam me)

GOST 6958-78 (cov tshuab ntxhua khaub ncaws loj)

GOST 11371 (cov qauv tiaj)

GOST 19752-84 (cov tiaj tiaj ua los ntawm cov hlau rau kev sib khi)

DIN 7603 A (sealing tooj liab rings)

Cov tooj liab -txhuas ntxhua khaub ncaws muaj hom tshwj xeeb - SHAM. Muaj qhov sib txawv ntawm txoj kab uas hla. Lwm hom:

DIN 125 (theem pib)

DIN 433 (nqaim, rau sab hauv)

DIN 7349 (rau lub caij nplooj ntoo hlav)

DIN 988 (kev txhawb nqa, rau kev hloov kho)

WIDE (hom lub cev)

Yuav ua li cas kom raug anneal

Nws yog qhov tsim nyog tua cov tshuab ntxhua khaub ncaws hauv qab lub taub hau yog tias tsuas yog txhawm rau daws kev nyuaj siab sab hauv uas tsis tuaj yeem tshwm sim thaum cov khoom ua tiav hauv kev tsim khoom. Tab sis nws yog ib qho tseem ceeb heev uas yuav tsum ua raws cov txheej txheem no kom meej. Cov txheej txheem yog ua tiav thaum ua kom sov txog 700 degrees . Tom qab ntawd cov ntu tau txias txias hauv qhov ib txwm muaj ntawm qhov kub ib txwm kom txog thaum lawv txias mus txog +25 degrees Celsius.

Kev kho cua sov yog ua los ntawm kev siv lub teeb ci vuam . Cov nplaim taws nyob hauv nws siv cov pa oxygen thiab acetylene muab los ntawm cov thooj voos kheej kheej sib txawv. Lwm qhov tseem ceeb - yuav tsum muaj hnab looj tes thiab tsom iav. Yuav tsum muaj lub tshuab tua hluav taws nyob ze qhov chaw ua haujlwm. Thaum txuas cov hoses mus rau lub tog raj kheej, nws yog qhov tsim nyog los qhib lub acetylene valve ntawm lub qhov hluav taws xob los ntawm 50%. Tom qab tua cov roj, tos kom txog thaum nplaim paj liab-liab tshwm tuaj.

Tom qab ntawd, cov pa oxygen tau qhib kom txog thaum lub nplaim taws xiav tshwm . Lub sijhawm no, cov ntxhua khaub ncaws raug hlawv. Qhov hluav taws kub tau qhia ntawm lub puck thiab qhia raws qhov saum npoo, ua tiav lub paj liab liab. Tom qab ntawd, tam sim kaw ob lub nkev li qub. Tom qab ntawd, raws li tau hais dhau los, koj yuav tsum tso cov khoom kom txias.

Qhov ntev (kho)

Qhov ntev ntawm cov tshuab ntxhua khaub ncaws tooj liab sib txawv heev raws li qhov tsim nyog tsim qauv thiab thaj chaw siv. Hauv kev coj ua hauv tsev, muaj cov hauv paus hauv qab no:

• sib khi tshuab ntxhua khaub ncaws rau KAMAZ 6x12x1 (1, 5), 8x12x1, 0;
• kev sib khi rau cov kav dej ntawm KAMAZ thiab MAZ 8x12x1, 5, 9x15x0, 7;
• rau KAMAZ cov tshuaj 9, 7x17, 5x1, 5;
• rau cov kab roj 10x16x1, 0 (1, 5).

Ib qho piv txwv zoo ntawm cov khoom lag luam nrog tuab 1 hli yog kev hloov kho 10x14x1. Qhov tseeb qhov ntev yuav yog 10, 3x14, 6x1, 0. Ib daim qauv hnyav 0, 67 g.

Tseem ceeb: tsuas yog cov kws tsim khoom lag luam Lavxias sim ua kom qhov ntev raws nraim.

Cov khoom tseem nrov nrog qhov loj me ntawm 5x10x1, ntxiv rau 10x12x1, 38x52x3. Cov khoom ntawm M10 pawg, suav nrog M10x14, txawv:

• nrog txoj kab uas hla ntawm 10 hli (tsis yog tsis muaj laj thawj tawm hauv qhov kev xaiv);
• hnyav 3 grams;
• nrog lub taub sab hauv ntawm 20 hli.

Thaum kawg, tooj liab ntxhua khaub ncaws hauv qhov ntau thiab tsawg hauv qab no yog xav tau hauv khw:

• M8;
• M12;
• M14;
• M16.
