Hardness yog ib qho qhia txog tias nyuaj npaum li cas los yog cov khoom muag zoo li cas. Tam sim no, feem ntau yog siv qhov kev ntsuas hardness nyob rau hauv cov khoom yog txoj hauv kev siv tawv tawv. Nws siv qee qhov ntsuas ntawm sab hauv tsev los mus nias lub nplhaib ntawm cov khoom siv hlau kuaj hauv qab ntawm ib qho kev thauj khoom, thiab tus nqi zog yog txiav txim siab raws li qib siab ntawm cov ntawv xovxwm. . Feem ntau yog siv Brinell hardness (HB), Rockwell hardness (HR
IB, HR
B, HRC) thiab Vickers Hardness (HV)
Raws li cov khoom siv hlau, screws kuj muaj qhov sib thooj qhov sib thooj. Lub hardness ntawm ib lub voos tsuas yog hais txog qhov nyuaj hardness ntawm lub hau. Cov nplaim ntawm ib qho kev sib tshuam yog qhov nyuaj ua rau ntawm lub qhov dej txias los yog ci / tig kev ntxhov siab. Rau sab hauv ntawm lub hau ntswj, tsis muaj qhov yuav tsum ua kom tsis muaj zog, tsuas yog cov kev ua tiav kev ua haujlwm. Xws li lub zog tensile, tawm dag lub zog thiab kev cuam tshuam toughness.
Yog hais tias koj xav kom nce lub hardness ntawm lub ntsia hlau, ib tug zoo txoj kev yog rau harden lub screw (chǔ lǐ). Kev cai screws muaj ib qho tseem ceeb ua haujlwm hauv kev lag luam, tsuav yog muaj kev lag luam hauv lub ntiaj teb, qhov kev ua haujlwm ntawm cov ntsia thawv tseem ceeb heev. Screws yog ib qho tsim muaj hauv tib neeg lub neej thiab kev tsim khoom rau ntau txhiab xyoo. Raws li daim ntawv sau npe, nws yog qhov tsim muaj ntau tshaj plaws ntawm noob neej. Cov txheej txheem ntawm kev ua kom muaj kev nyuab siab tsuas yog ua kom muaj kev kub ntxhov, cua sov, thiab kub hnyav ntawm qhov chaw. Feem ntau siv cov kev kho cua kub (chǔ lǐ).
Yog tias qhov ntau dua qhov nyuaj ntawm lub hau ntswj, qhov zoo dua? Tau kawg tsis. Precision Screws Me screws, tseem hu ua me quav screws, yog me me fasteners uas txuas cov khoom ntawm qhov khoom. Lawv yog cov me me, tab sis lawv tuaj yeem ua si lub luag haujlwm tseem ceeb hauv cov khoom tseem ceeb. Siv dav hauv hluav taws xob, hluav taws xob, khoom siv hluav taws xob, rooj tog vaj tog tsev, khoom siv thiab khoom siv. Cov ntsuas tsis yog tus qauv siv cov khoom fais fab thiab kev ua zauv ntawm qhov khoom siv qhov khoom tig thiab kev sib txhuam, thiab ua raws li cov cuab yeej cuab tam. Screws yog ib lub ntsiab lus rau cov fasteners, hais txhua hnub. Lub zog thiab toughness ntawm screws yog inversely proportional. Yog hais tias qhov kev mob siab dhau lawm, lub tornness ntawm lub hau ntswj yuav qis thiab nws yuav yooj yim tawg. Ntawm qhov tsis sib thooj, yog hais tias lub hau ntswj hardness tsawg, tus qauv hniav yuav yooj yim xaub. Lub viav vias uas txaus siab rau lub rooj sib hais yuav tsum tau ua tiav nrog qhov tswv yim ntawm cov ntaub ntawv siv tshuab, tsim, thiab ua cov txuj ci.
