Khoom siv
Hex txiv ntseej yog tsim los ntawm ntau yam khoom siv, txhua tus xaiv kom ua tau raws li cov kev xav tau tshwj xeeb hauv ntau daim ntawv thov. Cov hlau me me yog qhov kev xaiv dav dav rau dav dav - lub hom phiaj hex txiv ntoo vim nws cov nqi - kev ua tau zoo thiab lub zog txaus rau cov haujlwm tsis tseem ceeb hauv qhov chaw sab hauv tsev. Txhawm rau txhawb nws cov kav ntev thiab tiv thaiv corrosion, me me steel hex txiv ntoo feem ntau raug kho saum npoo xws li zinc plating, dub oxide txheej, lossis kub-dip galvanizing. Zinc plating muaj kev tiv thaiv xeb yooj yim, thaum kub - dip galvanizing muab cov txheej txheej tuab dua, ua kom haum rau kev siv sab nraum zoov.
Rau cov ntawv thov xav tau lub zog siab dua thiab zoo dua corrosion kuj, stainless hlau yog nyiam heev. Stainless hlau qib zoo li 304 thiab 316 tau siv dav. 304 stainless hlau muab zoo heev - lub hom phiaj corrosion kuj, ua rau nws haum rau ib tug dav spectrum ntawm sab hauv tsev thiab sab nraum zoov daim ntaub ntawv nrog rau nruab nrab ib puag ncig raug. 316 stainless hlau, uas muaj cov ntsiab lus molybdenum ntau dua, muaj kev tiv thaiv zoo rau cov tshuaj hnyav, dej ntsev, thiab cov xwm txheej huab cua, ua rau nws zoo tagnrho rau cov dej hiav txwv, tshuaj, thiab zaub mov - kev lag luam.
Hauv cov xwm txheej tshwj xeeb uas tsis yog xim hlau yog qhov tseem ceeb, xws li hauv hluav taws xob rwb thaiv tsev lossis ib puag ncig uas cov hlau sib txuas yuav tsum raug zam, nylon, polyethylene, lossis lwm yam khoom siv hluav taws xob tau ua haujlwm los tsim cov txiv ntoo hex. Cov txiv ntoo uas tsis yog xim hlau no yog lub teeb yuag, hluav taws xob rwb thaiv tsev, thiab tshuaj tiv thaiv, ua rau lawv tsim nyog rau cov khoom siv hluav taws xob, khoom siv kho mob, thiab hluav taws xob. Tsis tas li ntawd, tooj dag thiab txhuas yog qee zaum siv rau cov txiv ntoo hex hauv cov ntawv thov uas xav tau cov khoom zoo li hluav taws xob conductivity, cov yam ntxwv tsis sib nqus, lossis txo qhov hnyav.
Cov Qauv Khoom
Lub hex txiv ntseej khoom kab muaj ntau yam qauv categorized los ntawm qhov loj me, xov hom, qib zog, thiab cov yam ntxwv ntxiv:
Standard Hex ceev: Cov no yog cov yooj yim tshaj plaws thiab feem ntau muaj hex txiv ntseej, muaj nyob rau hauv ntau yam metric thiab imperial ntau thiab tsawg. Metric qhov ntau thiab tsawg feem ntau yog los ntawm M3 mus rau M64, thaum imperial qhov ntau thiab tsawg ntawm 1/8 "mus rau 4". Standard hex txiv ntseej muaj cov duab hexagonal tsis tu ncua nrog lub tiaj tiaj thiab cov qauv xov suab, ua rau lawv tsim nyog rau kev ua haujlwm dav dav hauv ntau qhov kev lag luam, suav nrog kev tsim kho, kev sib dhos tshuab, thiab DIY tej yaam num.
High - Lub zog Hex ceev: Engineered rau hnyav-lub luag hauj lwm daim ntawv thov, siab-lub zog hex ceev yog tsim los ntawm cov ntaub ntawv xws li hlau alloy. Lawv tau tsim los tiv thaiv lub zog tensile thiab shear zog, ua rau lawv qhov tseem ceeb rau kev ruaj ntseg cov tshuab hnyav, cov khoom siv loj loj, thiab cov khoom siv ua haujlwm nyob rau hauv siab loads thiab vibrations. High-lub zog hex txiv ntseej feem ntau muaj pom lub zog qib cov cim, xws li 8.8, 10.9, lossis 12.9 nyob rau hauv cov txheej txheem metric, qhia txog lawv cov khoom siv kho tshuab thiab kev thauj khoom - kev muaj peev xwm.
Fine - Xov Hex Ceev: Nrog rau cov xov me me piv rau tus qauv hex txiv ntseej, nplua - xov hex txiv ntseej muab kev hloov kho kom raug thiab txhim khu kev tiv thaiv kom xoob. Lawv feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau ua kom zoo, xws li hauv cov tshuab precision, cov khoom siv kho qhov muag, thiab cov cav tsheb, qhov twg yuav tsum muaj kev ruaj ntseg thiab raug ceev dua.
Tshwj xeeb - Feature Hex Ceev:
Flanged Hex Ceev: Cov txiv ntoo hex no muaj lub flange tiaj tus ntawm lub hauv paus, uas ua rau muaj kev sib cuag nrog cov mating nto. Qhov kev tsim no zoo faib cov khoom thauj thiab muab kev ruaj ntseg zoo dua, ua rau flanged hex txiv ntseej haum rau cov ntawv thov uas ob qho tib si ruaj ntseg thiab txhim kho kev thauj khoom - cov kabmob muaj peev xwm tseem ceeb, xws li hauv tsheb ncua kev kawm thiab rooj tog sib dhos.
Nylon - Ntxig Hex Ceev: Incorporating ib nylon insert, cov hex txiv ntseej muab anti-looning functionality. Cov nylon ntxig tsim kev sib txhuam thaum cov txiv ntseej yog threaded mus rau ib tug ntsia liaj qhov rooj, tiv thaiv loosening vim vibrations, shock loads, los yog rotational rog. Lawv tau siv dav hauv kev lag luam xws li automotive, aerospace, thiab industrial machinery, qhov chaw tiv thaiv kev ruaj ntseg yog qhov tseem ceeb tshaj plaws.
Countersunk Hex Ceev: Tsim los siv nrog lub tiaj tus - lub taub hau bolts, countersunk hex txiv ntseej tso cai rau lub taub hau ntsia liaj qhov rooj zaum yaug nrog rau saum npoo, tsim kom muaj kev zoo nkauj thiab zoo nkauj. Lawv feem ntau siv hauv kev ua haujlwm ntoo, ua rooj tog, thiab kev siv vaj tsev nyob qhov twg qhov dej ntws tawm yog xav tau.
Kev tsim khoom
Kev tsim cov txiv ntoo hex suav nrog ntau cov kauj ruam meej thiab nruj zoo - tswj kev ntsuas:
Kev npaj khoom siv: Cov ntaub ntawv zoo heev, suav nrog steel tuav, stainless hlau rods, yas pellets, los yog tooj dag / txhuas blanks, yog sourced. Cov ntaub ntawv no tau raug soj ntsuam nruj me ntsis rau cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov zoo ntawm qhov chaw kom ua tau raws li cov qauv tsim khoom. Cov ntaub ntawv hlau yog tom qab ntawd txiav rau hauv qhov ntev raws li qhov xav tau ntawm cov txiv ntoo loj.
Kev tsim: Hlau hex txiv ntseej feem ntau yog tsim los ntawm cov txheej txheem txias - taub hau lossis kub - forging txheej txheem. Txias - nqe lus yog ib txoj hauv kev los tsim cov me me - loj hex txiv ntseej, qhov twg cov hlau yog zoo li tus hexagonal daim ntawv thiab cov xov yog tsim nyob rau hauv ib los yog ntau theem siv tshwj xeeb tuag. Cov txheej txheem no muaj txiaj ntsig zoo rau cov khoom ntim siab thiab tuaj yeem tsim cov ntaub ntawv xov thiab cov txiv ntoo zoo. Kub - forging yog siv rau loj los yog siab dua - lub zog hex ceev, qhov twg cov hlau yog rhuab mus rau ib tug malleable lub xeev thiab ces zoo li tus nyob rau hauv siab siab kom ua tau raws li qhov xav tau lub zog thiab qhov tseeb. Cov txiv ntoo uas tsis yog xim hlau hex feem ntau yog tsim los ntawm kev txhaj tshuaj molding, qhov twg cov yas pellets yog yaj thiab txhaj rau hauv pwm kab noj hniav los tsim cov txiv ntoo zoo li.
Xov: Tom qab sib sau, cov txiv ntoo tau ua haujlwm threading. Rau cov txiv ntseej hlau, threading tuaj yeem ua tiav los ntawm dov lossis txiav. Xov dov feem ntau nyiam vim nws tsim cov xov muaj zog los ntawm txias - ua haujlwm ntawm cov hlau, txhim kho cov txiv ntoo kom qaug zog. Nyob rau hauv cov ntaub ntawv ntawm hex txiv ntseej, meej tswj yuav tsum tau thaum lub sij hawm threading los xyuas kom meej cov xov zoo thiab sib xws. Txiav threads yuav siv tau thaum xav tau siab dua rau cov ntawv thov tshwj xeeb lossis tshwj xeeb xov tsim.
Feature Fabrication (rau tshwj xeeb - hom hex txiv ntseej): Rau cov txiv ntseej hex nrog cov yam ntxwv tshwj xeeb, cov txheej txheem tsim khoom ntxiv tau koom nrog. Piv txwv li, flanged hex txiv ntseej muaj lub flange tsim thaum lub sij hawm forging los yog molding txheej txheem, nylon - ntxig hex txiv ntseej yuav tsum tau muab tso rau ntawm nylon insert, thiab countersunk hex txiv ntseej yuav tsum tau machined rau lub countersink lub kaum sab xis tsim nyog.
Surface Treatment (rau hlau ceev): Txhawm rau txhim kho kev tiv thaiv corrosion thiab txhim kho cov tsos, hlau hex txiv ntseej tuaj yeem dhau los ntawm ntau qhov chaw - txheej txheem kho. Zinc plating cuam tshuam nrog rau cov txiv ntoo hauv zinc - nplua nuj daws kom tso cov txheej txheem tiv thaiv. Kub - dip galvanizing coats cov txiv ntoo nrog ib txheej tuab thiab ntau ruaj ntawm zinc. Dub oxide txheej tsim ib txheej nyias, dub, corrosion-resistant txheej los ntawm cov tshuaj tiv thaiv. Cov kev kho saum npoo no tiv thaiv cov txiv ntoo los ntawm ib puag ncig yam thiab muab lawv cov kev zoo nkauj sib txawv.
Kev soj ntsuam zoo: Txhua pawg ntawm hex txiv ntseej raug tshuaj xyuas nruj heev. Dimensional checks yog ua los xyuas kom meej tias cov txiv ntseej txoj kab uas hla, thickness, xov specifications, thiab tej yam tshwj xeeb raws li cov qauv teev. Kev ntsuam xyuas txhua yam, xws li kev ntsuas lub zog tensile thiab hardness, yog ua los xyuas cov load - bearing peev thiab durability ntawm cov txiv ntseej. Rau cov txiv ntseej nrog cov yam ntxwv los tiv thaiv xoob, kev sim ntxiv yog ua kom ntseeg tau tias lawv cov txiaj ntsig zoo. Kev kuaj pom pom kuj tau ua los kuaj xyuas qhov tsis xws luag, tawg, lossis txheej txheej tsis raug. Tsuas yog cov txiv ntseej hex uas dhau tag nrho cov kev ntsuas zoo tau pom zoo rau ntim thiab xa tawm.
