Counterhead self-drilling screws

Cia peb hla lub suab nrov. Yog tias koj xav tias lub taub hau ntawm tus kheej-drilling ntsia hlau tsuas yog lub taub hau zoo nkauj nrog lub laum me ntsis, koj twb nyob tom qab ko taw. Qhov kev ua si tiag tiag yog nyob rau hauv kev sib cuam tshuam ntawm lub taub hau geometry, lub tshuab raj tsim, thiab cov khoom uas nws tau hais kom nkag mus. Kuv tau pom ntau yam haujlwm uas lub fastener raug liam tias ua tsis tiav, thaum qhov teeb meem yog qhov tsis sib haum xeeb txij thaum pib.

Lub Anatomy ntawm Ib Tug Zoo Counterhead

Nws tsis yog hais txog qhov qis profile xwb. Lub sij hawm 'counterhead' tau muab pov tseg ib ncig, tab sis cov ntsiab lus tseem ceeb yog lub hauv paus bearing nto thiab kev hloov ntawm lub taub hau mus rau lub shank. Ib qho kev tsim tsis zoo yuav tsis zaum tag nrho, tawm hauv qhov sib txawv rau corrosion, los yog yuav 'dhau ntawm dab dej' thiab deform cov khoom uas koj tab tom fastening. Kuv nco qab ib pawg los ntawm tus neeg muag khoom - yuav tsis sau npe - qhov twg lub taub hau lub kaum sab xis tau tawm los ntawm ob peb degrees. Ntawm daim ntawv, nws tau ntsib cov spec. Hauv kev xyaum, ntawm daim ntawv thov steel-rau-ntoo, nws tsim kev ntxhov siab tawg hauv cov ntoo txhua txhua lub sijhawm. Lub taub hau cia li tsav tsheb yam tsis tau koom nrog lub txee kom zoo.

Qhov ntawd yog qhov chaw tsim khoom tseem ceeb. Hauv cov chaw xws li Yongnian District hauv Handan, koj muaj pawg kws tshaj lij. Ib lub tuam txhab zoo li HANDAN ZITAI FREWER RAUG UA MOV., Ltd. nyob tsis muaj coincidence. Cov kev tsim kho vaj tse thiab cov khoom siv hauv thaj av ntawd, nyob ib sab ntawm txoj kev thauj loj xws li Beijing-Guangzhou Railway, txhais tau hais tias lawv feem ntau ua haujlwm nrog cov khoom siv raw thiab cov lus tawm tswv yim ntau dua uas cov chaw tsim khoom me me, cais tsis tuaj yeem nkag. Nws txhais mus rau qhov sib xws hauv cov txheej txheem stamping thiab kev kho cua sov uas txhais tau tias tus ntsia hlau lub nraub qaum.

Lub laum taw tes nws tus kheej yog lwm lub qhov luav. Rau tus kheej-drilling ntsia hlau ua haujlwm, qhov taw tes yuav tsum tau txiav, tshem tawm cov chips, thiab tom qab ntawd cov xov yuav tsum tsim yam tsis muaj galling. Kuv tau sim cov ntsia hlau qhov twg cov ntsiab lus yog nruj heev rau nyias gauge hlau - nws yuav xuas nrig ntaus tab sis tawm hauv ib lub qhov ragged uas cov xov tsis tuaj yeem ua kom huv si, ua rau cov xov stripped hauv qab vibration. Lub counterhead tsim compounds no; yog hais tias lub taub hau zaum ua ntej cov threads yog tag nrho cov koom nrog, koj tau txais ib tug cuav kev xav ntawm nruj. Ib lub lis piam tom qab, nws yog xoob.

Cov khoom sib txuam thiab qhov tseeb ntawm kev ua haujlwm

Koj tsis tuaj yeem muaj ib tus ntsia hlau rau txhua yam. Qhov kev xav tsis zoo tshaj plaws yog tias 10 counterhead self-drilling ntsia hlau yog qhov kho thoob ntiaj teb. Nyob rau hauv steel framing, siv ib tug hardened steel ntsia hlau rau hauv pre-galvanized channel yog tus qauv. Tab sis peb muaj ib qhov project retrofit nrog cov laus, weathered Corten steel panels. Cov ntsia hlau uas tau teev tseg, tus qauv zinc-plated hom, drilled zoo tab sis ntes ib nrab. Qhov teeb meem? Cov ntsiab lus tooj liab siab hauv Corten, ua ke nrog cov zinc txheej, tsim kom muaj kev sib khi hnyav heev. Qhov kev daws teeb meem yog hloov mus rau lub hau ntswj nrog cov txheej txheem txheej txheej sib txawv - qhov nthuav dav feem ntau saib tsis pom hauv thawj spec.

Qhov no yog qhov chaw logistical sab los ntawm ib lub chaw tsim khoom, zoo li Zitai txoj hauj lwm nyob ze ntawm Beijing-Shenzhen Expressway thiab National Highway 107, qhia nws tus nqi. Thaum koj xav tau ib qho tshwj xeeb, tsis yog txheej txheem txheej khiav-hais tias, geopolymer-raws li tiav rau kev cog tshuaj tshuaj-ua nyob rau hauv ib lub chaw tsim khoom ntom ntom txhais tau tias me me batch yooj. Lawv tuaj yeem muab cov txheej txheem, khiav txoj kab, thiab tau txais nws ntawm lub tsheb thauj khoom yam tsis muaj lub sijhawm ua cov hlau lead tib yam li lub Hoobkas nyob nruab nrab ntawm qhov tsis pom qhov twg. Lawv lub website, https://www.zitaifasteners.com, feem ntau teev cov peev txheej no, tab sis koj yuav tsum khawb dhau cov ntawv teev npe kom nkag siab txog qhov cuam tshuam: nws yog hais txog kev hloov pauv, tsis yog cov khoom muag ntau.

Cov ntaub ntawv tsis raug tsim nyog hais txog: siv lub taub hau ntsia hlau tsim rau cov hlau ntawm cov ntoo tawv tawv tawv. Lub logic yog nws tus kheej-drilling, yog li tsis muaj pilot qhov. Lub taub hau qis-profile yog ntshaw rau kev zoo nkauj. Cov screws snapped ntawm caj dab thaum lub caij ntoo txav. Zaj lus qhia? Lub ntsiab lus xyaum tsis tsim nyog rau ntoo, thiab lub shank, optimized rau qhov sib txawv shear rog nyob rau hauv hlau, yog nkig heev rau lub lateral load nyob rau hauv ntoo. Peb hloov mus rau qhov zoo sib xws counterhead style tab sis nyob rau hauv ib tug txawv qib thiab xov daim ntawv. Nws ua haujlwm.

Lub Teeb thiab Squeak

Torque teeb tsa ntawm cov tsav tsheb tau tshaj tawm, tab sis tsis tshua ua raws li qhov raug nrog cov ntsia hlau no. Lub counterhead yog txhais los kos cov khoom ua ke thiab nres. Tab sis yog hais tias lub laum taw tes tsis ua hauj lwm los yog lub flute yog clogged (feem ntau nrog txhuas los yog tej yam composites), tus neeg tsav tsheb yuav spinning, thiab lub torque hloov mus rau lub taub hau. Qhov no tuaj yeem yog cam-tawm thiab strip lub drive recess lossis, phem dua, tig cov ntsia hlau zaum, rhuav tshem cov xov hauv cov khoom niam txiv. Koj tau txais lub suab squealing - qhov ntawd yog qhov ua tsis tiav. Kuv tam sim no hais rau lub vaj huam sib luag xeem nrog cov khoom siv pes tsawg-up ua ntej kev teeb tsa loj pib. Nws yog tib txoj kev los ntsuas tus tsav tsheb thiab paub meej tias qhov kev xaiv ntsia hlau.

Qee zaum, kev kho yog counterintuitive. Ntawm qhov ntev fascia installation nrog cov xim sib xws, peb tau txais cov rooj zaum tsis sib xws. Lub taub hau txawm khav theeb los yog tog tob heev. Tom qab txiav txim tawm cov teeb meem tsav tsheb, peb saib cov ntsia hlau lawv tus kheej. Cov xim xim anodized, thaum zoo rau kev tiv thaiv corrosion, tau tsim kev sib txhuam tsis sib xws hauv qab lub taub hau. Ib qho roj nplua nyeem me ntsis ntawm lub ntsej muag ntxhua khaub ncaws - kov ntawm beeswax, ntawm txhua yam - ua qauv rau lub rooj zaum. Ib qho me me, yuav luag tsis tseem ceeb nthuav dav uas tsis nyob hauv ib phau ntawv.

Tshaj li Daim Ntawv Qhia Tshwj Xeeb: Sourcing thiab Consistency

Cov ntawv teev npe los ntawm cov chaw tsim khoom loj lossis ib qhov chaw zoo li Zitai's yuav muab koj cov khoom siv thiab qhov ntev. Dab tsi nws feem ntau yuav tsis qhia koj yog qhov ntau-rau-ntau sib xws hauv rooj plaub qhov tob hardening lossis qhov tseeb ntawm cov xov dov. Rau kev siv cov txheej txheem tseem ceeb, zoo li hauv kev tsim kho modular, qhov no yog txhua yam. Kuv tau pib thov kom muaj ntawv pov thawj ntawm cov khoom siv raw coil qhov chaw thiab lawv cov kev kuaj xyuas zoo ntawm lub taub hau tsim. Ib lub tuam txhab embedded nyob rau hauv ib tug loj ntau lawm puag xws li Yongnian District feem ntau yog teem rau hom traceability vim hais tias lawv pab cov neeg muas zaub uas xav tau nws rau export lag luam.

Nws kuj yog hais txog cov khoom seem. Lub taub hau ntsia hlau feem ntau tuaj nrog EPDM ntxhua khaub ncaws. Qhov zoo ntawm lub tshuab ntxhua khaub ncaws no tseem ceeb npaum li cov ntsia hlau. Ib tug pheej yig yuav degrade nyob rau hauv UV raug, poob elasticity, thiab cuam tshuam lub foob ntev ua ntej lub fastener tsis. Thaum ntsuas tus neeg xa khoom, tam sim no kuv thov kom pom cov khoom siv ntxhua khaub ncaws ib yam nkaus. Nws yog ib qho kev ua kom zoo.

Kev xav zaum kawg: evolution tsis nres. Peb tab tom pom ntau qhov kev thov rau kev sib xyaw ua ke - zoo li lub taub hau nrog lub tshuab sib xyaw ua ke uas tuaj yeem tuav cov ntawv hlau uas txhawb nqa los ntawm cov txheej txheem thermal rwb thaiv tsev. Nws thawb tus tsim. Cov chaw tsim khoom uas tuaj yeem rov ua dua sai sai, feem ntau cov khoom siv hauv zos muaj zog thiab cov koom haum engineering, yog cov daws cov teeb meem no. Nws yog qhov tsawg dua ntawm kev tsim cov ntsia hlau tshiab thiab ntau ntxiv txog kev tweaking cov ces kaum, txheej txheem tempering, thiab txheej txheej hauv txoj hauv kev meej. Qhov ntawd yog qhov kev txawj ntse tiag tiag, thiab nws yog dab tsi cais cov khoom lag luam fastener los ntawm kev daws teeb meem.
