Ntev Self Tapping Screws Rau Hlau

Ntev nws tus kheej tapping screws rau hlau yog ua los ntawm siab - zoo alloy steel uas tau undergone multi-theem quenching thiab tempering kub kho. Lub hardness saum npoo ncav cuag 450 txog 500 HV raws li Vickers hardness test. Lub zog tensile tsis tsawg tshaj 1,200 MPa. Nws ua tau raws li qhov yuav tsum tau muaj ntawm ISO 898-1 rau siab- lub zog fasteners, kom ntseeg tau tias cov xov yuav tsis nti thiab tus pas nrig yuav tsis ntswj thiab tawg thaum nkag mus rau cov hlau tuab. Ua piv txwv ntawm tag nrho qhov ntev ntawm 80 hli thiab txoj kab uas hla ntawm 6 hli ua piv txwv, ib txhij drilling thiab tapping xeem tau ua ntawm Q235 steel phaj nrog lub thickness ntawm 6 hli. Qhov siab tshaj plaws nkag mus rau lub zog siab tshaj plaws tsuas yog 20 Nm, thiab cov xov sib koom ua ke tom qab tapping mus txog ntau dua 95% los ntawm kev sib tw -section. , thiab tsis muaj qhov pom tseeb nti clogging lossis kub qaug zog thaum lub sijhawm teeb tsa, qhia tias lub kaum sab xis ntawm qhov drilling thiab nti zawj tsim ntawm cov ntsia hlau tuaj yeem ua tau zoo sib xws rau cov hlau txiav, thiab tsim nyog rau kev sib xyaw ua ke ntawm ntau txheej steel daim hlau lossis kev sib dhos ceev ntawm cov hlau coated.

Qhov saum npoo yog kho nrog zinc- aluminium composite txheej thiab ntxiv los ntawm sealant. Raws li qhov nruab nrab ntsev tsuag nrawm nrawm cov qauv ntsuas, tsis muaj qhov xeb liab tshwm sim ntawm lub hauv paus lub cev lossis xov hauv qab tom qab 800 teev ntawm kev txau tas li. Kev tiv thaiv- kev ua haujlwm corrosion yog ntau tshaj li ob npaug ntawm cov txheej txheem galvanized, ua tau raws li qhov ntev - lub sij hawm fastening xav tau ntawm cov khoom siv kev sib txuas lus sab nraum zoov lossis cov qauv ntawm ntug dej hiav txwv. Nyob rau hauv ib tug lateral load simulating cua-induced vibration, tom qab tau loaded rau 80,000 cycles ntawm ib zaus ntawm 25 Hz thiab ib tug amplitude ntawm 2.5 hli, cov seem preload quab yuam tseem nyob ntawm 92% ntawm tus nqi pib, ua pov thawj tias nws cov xov profile muaj kev tiv thaiv zoo heev - thiab kev sib txuas ntawm cov hlau yog qhov tshwj xeeb tshaj plaws. ntev - lub sij hawm dynamic loads, xws li photovoltaic brackets los yog cov suab nrov teeb meem.

Tus Tsov tus tw ntawm cov ntsia hlau yog nruab nrog tus kheej -centering qhia lub khob hliav qab, thiab ua ke nrog ob -edged laum tip qauv, ruaj khov drilling tuaj yeem ua tiav ntawm 4.5 hli tuab stainless hlau phaj yam tsis tas yuav tsum tau siv cov cuab yeej retraction thiab nti tshem tawm. Qhov no shortens lub sij hawm installation ntawm ib tug ntsia hlau los ntawm 60% piv nrog cov tsoos drilling ua ntej thiab ces tapping txheej txheem, ho txhim kho cov efficiency ntawm batch installation.

Tau txais cov duab kos los ntawm cov neeg siv khoom lossis tsim cov duab kos raws li lawv cov kev qhia tshwj xeeb lossis cov qauv.

Cov duab kos, cov khoom siv raw, kev kho deg, thiab lwm yam ntsiab lus tau lees paub los ntawm ob tog.

Muab cov lus tsocai, lees paub qhov kev txiav txim kom muaj nuj nqis, thiab suav nrog tag nrho cov ntaub ntawv ntsig txog.

Zoo li cov nqe lus ntawm kev them nyiaj, cov nqe lus ntawm kev lag luam, hom ntim, thiab lwm yam.

Thaum tsim cov khoom, ua raws li cov qauv kos duab thiab qauv.

Tom qab qhov kev tshuaj ntsuam zaum kawg, nws tau raug ntim thiab xa mus rau cov neeg siv khoom.
