Hex Bolt yog dab tsi?

 

Lub hex ntsia liaj qhov rooj yog tus qauv fastener nrog lub taub hau hexagonal thiab ib qho threaded sab nraud. Nws feem ntau yog siv nrog cov txiv ntseej thiab lub tshuab ntxhua khaub ncaws kom ua tiav qhov kev sib txuas txhim khu kev qha ntawm ob lossis ntau yam khoom los ntawm kev thov preload. Nws lub taub hau hexagonal pab txhawb torque daim ntawv thov siv cov ciaj ntswj lossis lub qhov (socket) cuab yeej, ua rau kev sib txuas ruaj khov thiab ua haujlwm tau zoo. Yog li ntawd, nws tau dhau los ua ib qho ntawm feem ntau thiab dav siv fasteners hauv kev lag luam.

Precisely vim hais tias hex bolts muaj cov yam ntxwv ntawm zoo load- bearing muaj peev xwm, siab standardization, siab sib dhos efficiency thiab yooj yim txij nkawm, lawv yog dav siv nyob rau hauv ntau yam lag luam xws li kev tsim kho, machinery, tsheb, zog, thiab tshuaj lom neeg kev lag luam. Cov kev lag luam sib txawv muaj qhov sib txawv ntawm lawv lub zog, kev tiv thaiv corrosion, qaug zog tsis kam thiab qhov tseeb qhov tseeb. Yog li ntawd, kev nkag siab txog lawv qhov kev thov tshwj xeeb yog qhov tseem ceeb rau kev xaiv tsim nyog thiab kev txiav txim siab yuav khoom. Tom ntej no, peb yuav nthuav dav nkag siab txog kaum qhov kev siv loj ntawm hex bolts los ntawm kab lus no.

 

 

 

I. Kev Tsim Kho thiab Hlau Structure Engineering

 

 

Kev tsim kho kev lag luam yog ib qho ntawm ntau qhov chaw siv hex bolts. Hauv kev tsim kho cov chaw tsim khoom niaj hnub no, cov tsev ua haujlwm, cov tsev siab - nce siab thiab txuas hniav, kev sib koom ua ke ntawm cov qauv steel cia siab yuav luag tag nrho ntawm bolts. Bolts yuav tsum tau dais tsis tau tsuas yog lub static load los ntawm tus kheej - hnyav ntawm lub tsev, tab sis kuj dynamic loads xws li cua load thiab av qeeg. Lub preload thiab installation ib ntus ntawm kev sib koom ua ke bolts yog ncaj qha cuam tshuam rau tag nrho kev ruaj ntseg thiab kev nyab xeeb ntawm cov qauv.

Bolt loosening, qaug zog tawg los yog kev ntxhov siab hauv zos los ntawm kev teeb tsa tsis raug ntawm qhov chaw tsim kho yog cov teeb meem engineering. Txhawm rau kom ua tiav ntev -lub sijhawm ruaj khov, cov kws ua haujlwm yuav xaiv qib siab- lub zog siab (Qib 8.8 thiab siab dua) bolts, thiab txais yuav kub-dip galvanizing lossis Dacromet los tiv thaiv- kev kho corrosion nyob rau sab nraum zoov. Stainless hlau tuaj yeem siv rau qee qhov xwm txheej hnyav.

 

• Qib siab zog (Qib 8.8 thiab siab dua) ua kom muaj kev nyab xeeb ntawm cov qauv thiab yoog raws li qhov yuav tsum tau ua kom muaj zog.
• Kev tswj nruj ntawm torque thiab preload kom tsis txhob muaj qhov sib txawv ntawm kev teeb tsa
• Kev siv kev sib txhuam-hom lossis preload- hom kev sib txuas tsim los txhim kho kev tiv thaiv - rub thiab tiv thaiv - shearing peev ntawm pob qij txha

Tsis tas li ntawd, thaum lub sij hawm tsim kho, tshwj xeeb torque wrenches thiab torque ntsuas cov cuab yeej feem ntau yog siv los xyuas kom meej tias txhua tus ntsia liaj qhov rooj ua tau raws li cov qauv tsim. Nyob rau tib lub sijhawm, rov- kev tshuaj xyuas ua haujlwm tom qab kev teeb tsa tiav kom tsis txhob muaj kev nruj nruj lossis dhau - zawm.

 

 

 

II. Heavy Machinery Manufacturing

 

 

Hauv cov khoom siv mining, metallurgical machinery, cranes thiab loj - nplai ua tshuab cov cuab yeej, hex bolts dais hnyav ua haujlwm ib puag ncig ntawm kev cuam tshuam, siab vibration thiab ntev - lub sij hawm qaug zog. Bolt loosening lossis tawg tuaj yeem ua rau cov cuab yeej kaw lossis txawm tias muaj kev nyab xeeb, nrog cov nqi tu siab thiab txaus ntshai heev.

Yog li ntawd, feem ntau ntawm cov tshuab no tau txais qib 10.9 lossis 12.9 alloy steel bolts (xws li 35CrMo, 40Cr), ntxiv los ntawm kev tiv thaiv -loosing designs, xws li lub caij nplooj ntoos hlav ntxhua khaub ncaws, nylon xauv txiv ntseej, xov locker lossis xauv pins. Cov kev sib faib hardness thiab toughness tswj tom qab kev kho cua sov yog lub hauv paus los xyuas kom meej ntev -lub sij hawm durability thiab qaug zog kuj. Nyob rau tib lub sijhawm, cov bolts yuav tsum raug rau saum npoo los tiv thaiv- kev kho corrosion kom tsis txhob muaj kev cuam tshuam los ntawm ib puag ncig corrosion.

 

• Ntau yam kev tiv thaiv -loosing ntsuas nyob rau hauv siab - cuam tshuam thiab siab - vibration ib puag ncig kom tshem tawm cov ntsia liaj qhov rooj loosening
