Kubaluleke kakhulu ukuvavanya ubulukhuni bekliphu yokusebenza ye-anchor. Ikliphu kufuneka ibe nobunzima obuthile ngexesha lokusetyenziswa ukuqinisekisa ukuthembeka kunye nokuqina komsebenzi wayo. Inkampani yaseLaihua inokwenza ngokwezifiso izibambiso ezikhethekileyo ezahlukeneyo ngokweemfuno, kwaye inokusebenzisa umvavanyi wobulukhuni beLaihua kuvavanyo lokuqina.
Umgangatho wovavanyo lokuqina kwekliphu yeankile ubhekisa ngokubanzi ku:
1. Rockwell ubulukhuni GB / T 230.1-2018
Lo mgangatho wamkela indlela yokuvavanya ubulukhuni be-Rockwell kunye ne-HRC Rockwell ubulukhuni isikali sokuvavanya, Le ndlela yokuvavanya ilula ukuyisebenzisa kwaye lolona khetho lufanelekileyo kubathengi.
2. Brinell ubulukhuni GB/T231.1-2018.
Lo mgangatho usebenzisa i-Brinell hardness HB isikali kuvavanyo.
Umgangatho wovavanyo ubhekisa koku:
GB/T 14370-2015 okanye JT/T 329-2010.
Ngenxa yobunzulu bemilo yekliphu ye-ankile, ngokwesayizi ye-clip taper yomthengi kunye nobukhulu bangaphakathi be-diameter ubukhulu, xa kuthengwa umvavanyi wobulukhuni, kuyimfuneko ukwenza izixhobo zobuchwephesha njengoko kufuneka ukuqinisekisa ukuchaneka kwexabiso elilinganisiweyo kunye nokwandisa. ubomi benkonzo yomvavanyi wobulukhuni. Ukuba kuyimfuneko, nceda uzive ukhululekile ukuthumela iisampuli zovavanyo.
Indlela yokuvavanya ukuqina kokuqhekeka kwezixhobo ze-carbide ezenziwe ngesamente nguVickers ubulukhuni (sebenzisa iVickers tester hardness):
Ukuqina kwe-carbide enesamente kufuneka kuhlolwe ngokubanzi kusetyenziswa i-Rockwell hardness A isikali. Xa ubukhulu bomsebenzi okanye isampuli bungaphantsi kwe-1.6 mm, indlela yokuqina kweVickers ingasetyenziselwa ukuvavanya. Ke yeyiphi indlela yokuvavanya ukuqina kokuqhekeka kwezixhobo ze-carbide ezenziwe ngesamente?
Umgangatho wovavanyo lokuqina kokwaphuka kunye nomgangatho wovavanyo lokuqina kwendlela yokuphunyezwa umgangatho wesiseko sezixhobo ze-carbide: JB / T 12616-2016;
Indlela yokuvavanya ngolu hlobo lulandelayo:
Okokuqala, yenza i-workpiece ukuba ivavanywe kwisampulu, emva koko upholise umphezulu wesampulu kwindawo yesipili, kwaye uyibeke phantsi komvavanyi we-microhardness ukuvelisa i-indentation kumphezulu ogudisiweyo kunye ne-conical diamond indenter yomvavanyi wobulukhuni. ukuba iintanda ezenziwe kwangaphambili zenziwe kwii-vertices ezine zokuhlenga-hlengisa.
Ixabiso lokuqina kokwaphuka (KIC) libalwa ngokusekwe kumthwalo wokuhlehla P kunye nobude bokwandiswa kokuqhekeka kwe-identation C.
I-Laizhou Laihua Testing Instrument Factory ihlala ikhona ukuphendula nayiphi na imibuzo onayo.
