Ezona zisetyenziswa kakhulu kwimveliso kukulukhuni kwendlela yoshicilelo, ezinje ngobuqili be-brinell, i-robwell ubunzima, iVisceds, ubunzima obuncinci. Ixabiso elifunyenweyo lobunzima limela ukumelana nomgangatho wensimbi ukuya kwingcaciso yeplastiki ebangelwa kukungenelela kwezinto zangaphandle.
Oku kulandelayo yintshayelelo emfutshane kwiiyunithi ezahlukeneyo zobunzima:
1. I-Brinell Hard (HB)
Cinezela ibhola yentsimbi eqingqiweyo yobukhulu obuthile (ihlala i-10mm ububanzi) kumphezulu wezinto ezinomthwalo othile (ngokubanzi i-3000kg) kwaye uyigcine kangangexesha elithile. Emva kokuba umthwalo ususiwe, umyinge womthwalo kwindawo yendawo ye-indult yixabiso le-Brinelly Ixabiso (HB), kwiKilogram Force / MM2 (N / MM2).
2. Ubunzima be-rockwell (hr)
Xa i-HB> 450 okanye isampulu incinci kakhulu, uvavanyo lwe-brinell alunakusetyenziswa kwaye umlinganiso we-rockwell umlinganiso kufuneka usetyenziswe endaweni yoko. Isebenzisa icone yedayimani nge-vertex ye-120 ° okanye ibhola yentsimbi enomgangatho we-1.59mm kunye ne-3.1mm ukucinezela phantsi komthwalo othile, kwaye ubunzima bezinto ezifumaneka kubunzulu bendlela. Ngokukalukhuni lwezixhobo zovavanyo, zinokubonakaliswa kwisikali esithathu esahlukileyo:
I-HRA: Bubunzima obufunyenwe ngokusebenzisa umthwalo we-60kg cone, kwaye usetyenziselwa izixhobo ezinzima kakhulu (ezinjengokukhuni kwe-carbide, njl. Njl.).
I-HRB: Bubunzima obufunyenwe ngokusebenzisa umthwalo we-100kg kunye nebhola yentsimbi enesithayisi ene-butter ye-1.58mm. Isetyenziselwa izixhobo ngobukhali obungaphantsi (ezinje ngentsimbi enesitayile, i-iron yentsimbi, njl. Njl.).
I-HRC: Bubunzima obufunyenwe ngokusebenzisa umthwalo we-150KG kunye ne-Inteni ye-Dinery Cone, kwaye isetyenziselwa izixhobo ezinzima (ezinje ngentsimbi enzima, njl.njl).
I-3 Viskers Hardy (HV)
Sebenzisa i-Inerter yeDimayi yeDiamond ye-Dired ngomthwalo ongaphantsi kwe-120kg kunye ne-vertex ye-vertex ye-136 ° ukucinezela kwindawo yemiba yomhlaba, kwaye yahlula-hlula indawo yexabiso le-HV ngexabiso le-HV (kg / mm2).
Xa kuthelekiswa ne-brinell kunye neemvavanyo ezinzima zeRockwell, uvavanyo lweViskers lunezibonelelo ezininzi. Ayinawo iingxaki zeemeko ezichaziweyo zomthwalo we-p kunye ne-Inderter Diemeter D njenge-Brinell, kunye nengxaki yokulahleka kweNdawo; kananjalo ayinayo ingxaki yokuba ixabiso elinobunzima le-rockwell alinalwazi. Kwaye inokuvavanya naziphi na izinto ezithambileyo nelukhuni njenge-robwell, kwaye inokuvavanya ubunzima bamacandelo anqabileyo kakhulu (okanye iintambo ezinqabileyo) zingcono kune-rockwell, enokwenziwa kuphela ngobuqili be-rockwell. Kodwa phantsi kweemeko ezinjalo, kunokuthelekiswa kuphela kumgangatho we-rockwell, kwaye awunakuhlanganiswa namanye amanqanaba obunzima. Ukongeza, kuba i-robwell isebenzisa ubunzulu be-induction njengesalathiso somlinganiso, kwaye ubunzulu bobunzulu buhlala buncinane kunobubanzi bobubanzi, ke imposiso yayo ikwaninzi. Ke ngoko, idatha ye-rockwell yedatha ayizinzanga njenge brinell kunye nabavukeli, kwaye ngokuqinisekileyo ayizinzanga njengabaphumeleleyo.
Kukho ubudlelwane obuthile bokuguqula phakathi kwebrinell, iRockwell noColkers, kwaye kukho itheyibhile yolwalamano olunokufundwa.
IXESHA LOKUQALA: UMar-16 ukuya ku-2023
