Basa uye Kurongwa kweMakukutu eKuoma muKuedza Kuoma

Mukuita kwekuyedza kuomarara, mabhuroko akajairwa ekuomarara akakosha. Saka, basa remabhuroko ekuomarara nderei, uye anorongwa sei?

I.Zvidhinha zvekuomarara zvinonyanya kuita mabasa matatu mukuyedza kuomarara: kuyera vanoedza kuomarara, kuenzanisa data, uye kudzidzisa vanoshanda.

1.Panguva yekushandiswa kwenguva refu kwemuchina wekuyedza kuomarara, shanduko dzinogona kuitika mumasensa emuchina kana magadzirirwo emakanika. Saka, tinoshandisa mabhuroko akajairwa ane mavalue anozivikanwa ekuomarara kuti tione kana kugadzirisa kururama kwemuchina wekuyedza kuomarara. Bhuroko rega rega rekuomarara rakanyorwa kuti rine value yekuomarara; kuyedza nebhuroko rekuomarara usati waonekwa zviri pamutemo kunogona kugadzirisa kukosha kwemuchina wekuyedza kuomarara, kubvisa zvikanganiso zvemidziyo, kuve nechokwadi chekuti data rekuyera rinosangana nezvinodiwa zvakajairwa, kusimbisa kugadzikana kwemuchina wekuyedza kuomarara, uye nekukurumidza kuona kana muchina wekuyedza kuomarara uri mumamiriro akajairika ekushanda.

2. Kuburikidza nekuongororwa kwemabhuroko ekuomarara ane zvirevo zvakabatana, kuenzanisa kwemhedzisiro yebvunzo kunogona kuwanikwa pakati pevanoedza kuomarara vakasiyana nevaongorori vakasiyana. Nekupa mareferensi akajairwa ane hunhu hwekuomarara hunozivikanwa, zviyero zvebvunzo pasi pevanoedza kuomarara vakasiyana uye mamiriro akasiyana ekuyera zvakabatana.

3. Zvidhinha zvekuomarara zvakajairwa zvinowanzo shandiswawo mukudzidziswa kwevashandi mumarabhoritari kana mafekitori kuvandudza hunyanzvi hwekushanda.

Kukosha kwavo kwekuomarara kunoongororwa nemasangano ane mvumo, zvichiratidza kurongeka, kururama, uye kugadzikana. Zvinhu zvemabhuroko ekuomarara zvakafanana nezviri muchikamu chebasa chinofanira kuyedzwa (senge simbi, purasitiki, nezvimwewo), izvo zvinogona kuenderana nenzira dzakasiyana dzekuyera kuomarara (Brinell, Rockwell, Vickers, nezvimwewo).

II.Kurongwa kwezvidhinha zvekuomarara kunonyanya kuenderana nezviyero zvakasiyana zvekuomarara, mhando dzezvinhu, uye huwandu hwehukoshi hwekuomarara. Mhando dzakajairika ndeidzi dzinotevera:

1. Kupatsanura neKuyera Kuoma Nzira

Iyi ndiyo nzira inonyanya kushandiswa yekupatsanura, inoenderana nemhando dzevaongorori vehukukutu:

Matombo eKuomarara eRockwell (HRC, HRB, nezvimwewo): Anoshanda nevayedzi veKuomarara veRockwell, anoshandiswa pakuongorora kuomarara kwezvinhu zvesimbi nguva dzose.

Brinell Hardness Blocks (HBW): Inoshanda nevayedzi veBrinell hardness, yakakodzera kuyera simbi dzine kuoma kwakaderera kana zvinhu zvine tsanga dzakakora.

Vickers Hardness Blocks (HV): Inoshanda nevayedzi veVickers hardness, ine kunyatsojeka, uye inogona kuyera workpieces dzakatetepa, zvikamu zvidiki, uye zvidimbu zvakaomeswa pamusoro.

Zvivharo zveKuoma kweMatombo (HS): Zvinoenderana nevayedzi veKuoma kweMatombo, zvinonyanya kushandiswa pakuyedza kuoma kwezvishandiso zvikuru kana michina isingafambi.

Leeb Hardness Blocks (HL): Inoenderana nevaongorori veLeeb hardness, yakakodzera kuyedzwa panzvimbo uye kwete kuparadza.

2. Kupatsanurwa neZvinhu

Zvivharo zveSimbi: Zvinosanganisira simbi yekabhoni, simbi yesimbi, simbi isingatsvi, simbi yemhangura, nezvimwewo, zvichizadzisa zvinodiwa pakuedza simbi dzakawanda dzemaindasitiri.

Zvidhinha Zvekuoma Zvisiri zvesimbi: Zvakadai sepurasitiki, rabha, uye ceramic hardness blocks, izvo zvinoenderana nekuyera kuoma kwezvinhu zvisiri zvesimbi.

3. Kurongwa neGiredhi Rakarurama

Giredhi Rakajairika (Giredhi 1): Rinoshandiswa pakuenzanisa vanoedza kuomarara, nerunyoro rwakanyanya uye kutevedza mitemo yenyika.

Giredhi Rekushanda (Giredhi 2): Rinoshandiswa pakuenzanisa kuyedza kwezuva nezuva uye kusimbisa kugadzikana kwechishandiso, richizadzisa zvinodiwa nekuyedza kugadzirwa kwenguva dzose.

Pakutenga ma hardness blocks, zvinodikanwa kufananidza rudzi rwe hardness tester, huwandu hwe hardness ye workpiece inofanira kuyedzwa, uye zvinodiwa zve accuracy. Calibration inofanira kutevedzera misimboti ye "miyero yakafanana, mamiriro akafanana, uye standardized operation" kuti ive nechokwadi chekuti qualitative uye trackability ye qualitatives dzakayerwa yakarurama.
