Indlela yokuvavanya ubulukhuni be-40Cr, i-40 chromium Rockwell

Emva kokucinywa nokufuthwa, i-chromium ineempawu ezintle kakhulu zoomatshini kunye nokuqina okuhle, nto leyo eyenza ukuba isoloko isetyenziswa ekwenzeni izibophelelo ezinamandla aphezulu, iibheringi, iigiya, kunye nee-camshafts. Iimpawu zoomatshini kunye novavanyo lobunzima ziyimfuneko kakhulu kwi-40Cr ecinyiweyo nefuthwayo.

Uvavanyo lobunzima be-40Cr ludla ngokusebenzisa indlela yovavanyo lobunzima beRockwell kunye nendlela yovavanyo lobunzima beBrinell xa kuvavanywa. Ngenxa yokuba isivavanyeli sobunzima beRockwell sikhawuleza kwaye silula ukusisebenzisa, sidla ngokukhethwa ngabathengi. Kwiindawo ezincinci okanye iindawo ezifuna ukuchaneka okuphezulu, isivavanyeli sobunzima beVickers singasetyenziswa.

Ngokwesiqhelo, ubunzima beRockwell obuyi-40Cr emva kokucinywa kunye nokuthomalaliswa buhlala bufuneka ukuba bube phakathi kwe-HRC32-36, ukuze bube namandla aphezulu kunye nokumelana nokudinwa.

Ezi zilandelayo ziindlela ezininzi ezisetyenziswa kakhulu zokuvavanya ubulukhuni beRockwell:

1. Isibonisi sombane sedijithali esongeziweyo ngobunzima Umvavanyi wobunzima beRockwell: ngokuchanekileyo, ngokuthembekileyo, okuhlala ixesha elide, nokusebenza kakuhle kovavanyo; isibonisi sedijithali sinokufunda ngokuthe ngqo ixabiso lobunzima beRockwell, ulwakhiwo loomatshini lulungisiwe, kwaye ezinye izikali zeRockwell zinokulinganiswa ngokuzikhethela. Isebenzisa itekhnoloji yokulayisha nokukhupha umbane ngokuzenzekelayo ukuze kususwe iimpazamo zabantu. Inkqubo yespindle isebenzisa isakhiwo sespindle esingenasiphazamiso ukuphucula ukuchaneka kwamandla okuqala ovavanyo.

2. Isibonisi sedijithali sesikrini sokuchukumisa iRockwell hardness tester: ukusebenza kwesikrini sokuchukumisa see-intshi ezisibhozo, i-interface elula nelula ukuyisebenzisa; amandla ovavanyo lokulayisha nge-elektroniki, izinga lokusilela eliphantsi, uvavanyo oluchanekileyo ngakumbi, lunokugcina ngokuzimeleyo iiseti ezingama-500 zedatha, lucime ngaphandle kokulahleka kwedatha, ngokuhambelana ne-ISO, i-ASTM E18 kunye neminye imigangatho.

3. Isivavanyeli sokuqina seRockwell esizenzekelayo ngokupheleleyo: amandla ovavanyo lokulayisha nge-elektroniki asetyenziselwa ukuphucula ukuchaneka kwexabiso lamandla, ukucofa kube kanye ukugqiba yonke inkqubo yovavanyo lokuqina, kulula kwaye kusebenza kakuhle; iqonga lovavanyo elikhulu kakhulu, elifanelekileyo ngakumbi ekufumaneni ubunzima bomsebenzi omkhulu; lixhotyiswe nge-joystick yokuqhuba ngokukhawuleza i-servo motor ukulungisa indawo yovavanyo; idatha ingadluliselwa kwikhompyutha nge-RS232, i-Bluetooth okanye i-USB.
