Yuav ua li cas xaiv qhov zoo wrench

Txoj cai xaiv ntawm wrenches:

HOOMR muab qhov tseem ceeb rau lub thawv wrenches thiab lub qhov (socket wrenches), ua raws li lub qhov ncauj wrenches thiab adjustable wrenches.

Cov khoom siv dab tsi yog qhov zoo: cov khoom siv tes yog feem ntau carbon steel thiab alloy steel, alloy steel feem ntau chromium vanadium steel; Ming vanadium steel daim ntawv lo ntau heev, feem ntau hais lus, siab dua daim ntawv lo, qhov zoo dua. Cov khoom siv carbon steel feem ntau yog siv rau cov khoom siv qis, chromium vanadium steel - feem ntau yog siv rau cov khoom qib siab.

Zoo li style:

Muaj ntau hom kev siv ob lub ntsej muag, cov pa sib sib zog nqus shin, concave ci ntsa iab, tiaj tus ci ntsa iab peb. Txhua yam txheej txheem ntau lawm tsis zoo ib yam, kev kho saum npoo kuj sib txawv heev. Convex tibia feem ntau yog carbon steel, concave tibia yog feem ntau alloy steel.

Punching zoo:

plum zoo tag nrho, zoo nkauj nkhaus, phab ntsa thickness yog txawm, ntau tus qauv. Nyob rau hauv kev rau txim, lub glucoside yog puag ncig, thiab sab nraud yog heev maj mam thiab du. Sab hauv phab ntsa ntawm lub qhov yog du thiab zoo ib yam, tsis muaj burr thiab hniav cim. Handshake, puag ncig, tsis ya ntug.

Kev kho saum npoo:

Muaj ntau hom kev kho deg, polishing, daim iav, frosted pos huab, blackening, electrophoresis thiab lwm yam. Muaj ntau qhov sib txawv me ntsis hauv cov huab cua frosted.Ntawm lawv, watermark pos huab yog qib siab tshaj plaws. Lwm qhov tseem ceeb heev yog qhov zoo ntawm cov lus qhia saum toj no thiab cov cim lag luam. Lub logo thiab cov lus qhia tshwj xeeb yuav tsum tau meej thiab meej, thiab cov font yuav tsum sib npaug thiab ua kom zoo.

Thickness:

Qhov me me lub thickness ntawm tus ciaj ntswj ntawm tib lub specification, qhov siab dua qhov yuav tsum tau ntawm torsion thiab lwm yam qauv, lub sib dua qhov hnyav, qhov ntau xis siv ntawm cov neeg, yog li qhov zoo yog hais txog qhov zoo.

Tolerance ntau:

Piv txwv li, 14MM txiv ntseej, sib txuas 14MM qhib; Kev rau txim xav tau kev nthuav dav kom tsim nyog, yog qhov tsim nyog rau kev sib koom tes sai; Txawm li cas los xij, nws tsis tsim nyog los ua kom loj dhau, uas yuav ua rau cov txiv ntoo puas thiab ua rau nws "nkim". Yog li koj yuav tsum muaj tseeb hauv qhov qhib lossis quinceum.

Torsion thiab hardness: zoo heev yog qhov yuav tsum tau muaj kev sib xyaw ua ke zoo tshaj plaws ntawm hardness thiab toughness, nyuaj toughness tsis yooj yim tawg; Mos dhau thiab yooj yim rau cov duab.
