Ipayipi Elingenasici
Ukuqina :
Amashubhu ensimbi engagqwali avame ukusetshenziswa ukukala ubulukhuni beBrinell, Rockwell kanye neVickers.Ubulukhuni be-Brinell Phakathi kwezindinganiso zamapayipi ensimbi engagqwali, ubulukhuni be-Brinell yibo obusetshenziswa kakhulu, futhi ukuqina kwempahla kuvame ukuvezwa ngobubanzi bokungena, okubili okunembile futhi okulula.Kodwa-ke, ayifaneleki amapayipi ensimbi ensimbi eqinile noma encane.
Ukuqina kwe-Rockwell:
Ishubhu lensimbi engagqwali Ukuhlola ubulukhuni be-Rockwell kuyefana nokuhlola ubulukhuni be-Brinell.Umehluko wukuthi ikala ukujula kwe-indent.Ukuhlolwa kokuqina kwe-Rockwell kuyindlela esetshenziswa kabanzi lapho i-HRC isetshenziswa khona okwesibili ngemuva kokuqina kwe-Brinell HB ezindinganisweni zamapayipi ensimbi.Ubulukhuni be-Rockwell bungasetshenziswa ekunqumeni izinto zensimbi ukusuka ekuthambile kakhulu kuye kokuqina kakhulu.Inxephezela indlela ye-Brinell.Ilula kunendlela ye-Brinell futhi ingafunda ngokuqondile inani lokuqina kusuka kumshini wokuqina.Kodwa-ke, ngenxa yokuhlehlisa okuncane, inani lokuqina alinembile njengendlela ye-Brinell.
Vickers ubulukhuni
Ishubhu yensimbi engagqwali yokuhlola ubulukhuni be-Vickers nayo iyindlela yokuhlola yokuhlehlisa yokulinganisa izinto zensimbi ezacile kakhulu kanye nokuqina kongqimba lwangaphezulu.Inezinzuzo eziyinhloko zezindlela ze-Brinell ne-Rockwell, futhi inqoba ukushiyeka kwayo okuyisisekelo, kodwa ayilula njengendlela ye-Rockwell.Indlela ye-Vickers ayivamisile ukusetshenziswa ezindinganisweni zamapayipi ensimbi.
Ukuhlolwa kokuqina
Ishubhu lensimbi engagqwali linobubanzi obungaphakathi obungu-6.0mm noma ngaphezulu kanye neshubhu lensimbi engenasici elinogqinsi oluyi-13mm noma ngaphansi.Kungaba i-W-B75 yokuhlola ubulukhuni be-Vickers.Kuyashesha kakhulu futhi kulula ukuhlola futhi kulungele ukuhlolwa okusheshayo nokungonakali kwamapayipi ensimbi engagqwali.Amashubhu ensimbi engagqwali anobubanzi bangaphakathi obungaphezu kuka-30 mm nogqinsi lodonga olukhulu kuno-1.2 mm ahlolwa ngesihloli sokuqina se-Rockwell ukuze kuhlolwe ubulukhuni be-HRB ne-HRC.Amashubhu ensimbi engagqwali anobubanzi bangaphakathi obungaphezu kuka-30 mm nogqinsi olungaphansi kuka-1.2 mm ahlolwa ngomshini wokuhlola ubulukhuni be-Rockwell ukuze kuhlolwe ubulukhuni be-HRT noma i-HRN.Emapayipini ensimbi engagqwali anobubanzi bangaphakathi obungaphansi kuka-0 mm nangaphezulu kuka-4.8 mm, ubulukhuni be-HR15T kuhlolwa umhloli wokuqina we-Rockwell okhethekile wamapayipi.Lapho ububanzi bangaphakathi beshubhu yensimbi engagqwali bukhulu kuno-26 mm, ukuqina kodonga lwangaphakathi lweshubhu nakho kungahlolwa yi-Ro.
