Namhlanje ndingathanda ukwazisa kuwe umvavanyi wobulukhuni beRockwell ongaphaya kwamandla amancinci ovavanyo kunomvavanyi wobulukhuni beRockwell:

Umvavanyi wobulukhuni be-Rockwell luhlobo lovavanyo lobulukhuni lwe-Rockwell.Isebenzisa amandla amancinci ovavanyo.Xa uvavanya izixhobo zokusebenza ezincinci nezincinci, ukusebenzisa umvavanyi wobulukhuni beRockwell kuya kukhokelela kumaxabiso angachanekanga.Singasebenzisa iSuperficial Rockwell hardness tester.Umvavanyi wobulukhuni unokusetyenziselwa ukulinganisa izixhobo zokusebenza kunye neeleya eziqinileyo eziPhezulu.
Umgaqo wayo wokuvavanya uyafana ncam nalowo we-Rockwell hardness tester.Umahluko kukuba amandla ovavanyo lokuqala yi-3KG, ngelixa uvavanyo lokuqala lwamandla ovavanyo oluqhelekileyo lwe-Rockwell luyi-10KG.

Inqanaba lamandla okuvavanya ubulukhuni beRockwell: 15KG, 30KG, 45KG

I-indenter esetyenziswe kwi-Superficial Rockwell tester yokuqina iyahambelana ne-Rockwell yokuvavanya ubulukhuni.:

1. 120degree diamond cone indenter

2. 1.5875 i-indenter yebhola yentsimbi

Rockwell Superficialisikali somvavanyi wobulukhuni:

HR15N, HR30N, HR45N, HR15T, HR30T, HR45T

(Isikali se-N silinganiswa nge-indenter yedayimane, kwaye isikali sika-T silinganiswa nge-indenter yebhola yentsimbi)

Ubunzima bubonakaliswanjengoko: ixabiso lobulukhuni kunye nesikali Rockwell, umzekelo: 70HR150T

I-15T ithetha i-indenter yebhola yentsimbi kunye novavanyo olupheleleyo lwe-147.1N (15 kgf) kunye ne-indenter ye-1.5875

Ngokusekelwe kule cha ngasentlaRacteristics, Superficial Rockwell ineenzuzo zilandelayo:

1. Ekubeni inezimbiniiintloko zoxinzelelo, zifanelekile zombini izinto ezithambileyo kunye nezilukhuni zetsimbi.

2. Amandla ovavanyo yi-smaller kunaleyo Rockwell ubulukhuni tester, kwaye umonakalo Superficial of workpiece incinci kakhulu.

3. I-forc yovavanyo encincie ingathatha indawo yeVickers hardness tester, enoqoqosho kwaye efikelelekayo.

4. Inkqubo yokuvavanya ikhawuleza kwaye i-workpiece egqityiweyo inokubonwa ngokufanelekileyo.
