Intshayelelo ye-rockwell engaphezulu kunye ne-Plastic Rockwell hardness tester

Uvavanyo lobunzima beRockwell lwahlulwe lwaba luvavanyo lobunzima beRockwell kwaye oluphezulu

Uvavanyo lokuqina kweRockwell.

Uthelekiso lwe-superficial rockwell hardness tester kunye ne-rockwell hardness tester:

Uvavanyo lwamandla omvavanyi wobunzima be-rockwell: 60kg, 100kg, 150kg;

Uvavanyo lwamandla oluphezulu lwe-rockwell hardness tester: 15kg, 30kg, 45kg ；

Isikali somvavanyi wobulukhuni be-rockwell: i-HRA, i-HRB, i-HRC kunye nezinye iintlobo ezili-15 zezikali;

Isikali sovavanyo lobunzima be-rockwell engaphezulu: HR15N, HR30, HR45N, HR15T

kunye nezinye iintlobo ezili-15 zezikali;

Ezi ntlobo zimbini zovavanyo lobunzima be-rockwell kwindlela yokusebenza, indlela yokufunda, umgaqo wovavanyo ziyafana, kwaye zombini ngokwezinga lokuzenzekelayo zingahlulwa zibe ngamanqanaba amane enziwe ngesandla, ngombane, ngokubonisa ngedijithali, ngokuzenzekela, ngenxa yokuba ixabiso lamandla ovavanyo lobunzima be-superficial rockwell lincinci kunelo liqhelekileyo, ngoko ke ubunzima be-superficial rockwell bunokulinganiswa njenge-workpiece encinci.

Ukusetyenziswa kwePlastic Rockwell hardness tester:

Ifanelekile kwiplastiki, irabha eqinileyo, izinto zokungqubana, i-resin yokwenziwa, i-aluminium tin alloy, ikhadibhodi kunye nezinye izinto zokumisela ubulukhuni.

Izikali zovavanyo eziphambili: HRE, HRL, HRM, HRR;

Uluhlu lokulinganisa: 70-100HRE, 50-115HRL, 50-115HRM, 50-115HRR;

Kukho iintlobo ezintathu eziphambili ze-indenter yokuqina kwe-Rockwell yeplastiki, ngokulandelanayo: i-indenter yebhola yentsimbi: 1/8 “, 1/4 “, 1/2 ;

Udidi: Umvavanyi wobulukhuni bePlastiki weRockwell ngokwezinga lokuzenzekelayo unokwahlulwahlulwa zibe: umvavanyi wobulukhuni bePlastiki weRockwell, umvavanyi wobulukhuni bePlastiki weRockwell, umvavanyi wedijithali wePlastiki weRockwell, umvavanyi wobulukhuni bePlastiki weRockwell ziintlobo ezi-3. Imo yokufunda: incwadi yesandla kunye neyombane zifundwa ngocingo, umboniso wedijithali kukufunda ngokuzenzekelayo kwesikrini sokuchukumisa;

Imigangatho yovavanyo lokuqina kweRockwell kwiiplastiki, kuquka i-American Rockwell Standard ASTM D785 yeeplastiki, i-Rockwell standard ISO2039 yamazwe ngamazwe kwiiplastiki, kunye ne-Chinese Rockwell standard GB/T3398.2,JB7409 yeeplastiki.

I-HRA – Ifanelekile ukuvavanya ubulukhuni bezinto eziqinileyo okanye ezibhityileyo, ezifana ne-carbide, intsimbi eqinileyo eyenziwe nge-carburized, imicu yentsimbi eqinileyo, iipleyiti zentsimbi ezibhityileyo, njl.njl.

I-HRB- Ifanelekile ukuvavanya izixhobo zobunzima obuphakathi, ezifana nentsimbi ephakathi nephantsi yekhabhoni emva kokutsalwa, isinyithi esinyibilikayo, iibrasses ezahlukeneyo kunye noninzi lweebronze, ii-alloys ezahlukeneyo ze-duralumin emva konyango lwesisombululo kunye nokuguga.

I-HRC -Ifanelekile ukuvavanya intsimbi yekhabhoni, intsimbi ye-alloy kunye nentsimbi yesixhobo emva kokucima kunye nokushisa okuphantsi kobushushu, kunye nokulinganisa intsimbi ye-cast ebandayo, intsimbi ye-cast ethambileyo ye-pearlite, i-titanium alloy njalo njalo.

I-HRD- Ifanelekile ukucinezela ubunzulu phakathi kwesikali se-A kunye ne-C sezinto ezahlukeneyo, ezifana nesampuli yentsimbi eqinisiweyo yonyango lobushushu bomphezulu, isinyithi esithambileyo esithambileyo se-pearlite.

I-HRE- Ifanelekile ukuvavanya isinyithi esijikelezileyo, i-aluminium alloy, i-magnesium alloy, i-bearing alloy kunye nezinye izinyithi ezithambileyo.

I-HRF- Ifanelekile kwi-copper eqinileyo, i-copper ebomvu, i-aluminium alloy ngokubanzi, njl.

HRH- Ifanelekile kwii-alloys zesinyithi ezithambileyo ezifana ne-aluminium, i-zinc kunye ne-lead.

HRK- Ifanelekile kwii-bearing alloys kunye nezinye izinto zesinyithi ezithambileyo.
