Dzidzisai kuziva mhando yebhaudhi nekukurumidza

Bolt inhengo dzakajairika dzemakanika, dzinowanzoshandiswa munzvimbo dzakawanda, dzinoshandiswa nemusoro uye nescrew zvikamu zviviri zveboka rezvisungo, dzinofanira kushandiswa pamwe chete nenati, inonyanya kushandiswa kusungira kubatana kwezvikamu zviviri nemaburi. Pamwe hauna kunzwisisa kwemhando yezvinhu zvebholt, chinyorwa chino chichakuzivisa nezvemhando yezvinhu zvebholt, ruzivo rwakabatana negiredhi, kuitira kuti vanhu vakawanda vadzidze kuziva hunhu hudiki hwebholt.

Magiredhi nezvinhu zvemabhaudhi zvinorevei?

Giredhi rebhoti rinoreva kuti bhoti iri 4.8 giredhi, 8.8 giredhi, 10.9 giredhi uye mamwe mabhoti.

Zvinhu zvinoreva kuti bhaudhi rakagadzirwa nezvinhu zvakaita seQ235, 35K, 40Cr, 45 # simbi, 35CrMo simbi, 304 simbi isingatsvedzeri uye 316 simbi isingatsvedzeri nezvimwewo.

Bolt grade nezvinhu zvine hukama hwakati, simbi diki inogona kungoburitsa mabhoti ane simba shoma, simbi ine kabhoni yepakati inogona kugadzira mabhoti ane simba repakati, simbi ine kabhoni yakawanda, alloy steel inogona kugadzira mabhoti ane simba repamusoro. Mamwe mabhoti anotsanangura kuumbwa kwemakemikari anoenderana uye hunhu hwemakanika, asiwo kuti aone kuti chinhu chacho ndechei.

Heino runyorwa rwemhando dzakajairika dzemabhaudhi dzinogona kuva zvinhu zvakaita sei. 4.8 level inogona kuva Q235, Q195 nezvimwe zvinhu zvesimbi zvakapfava. 5.8 level Q235 pamusoro pezvose zvinhu zvinogona kuva, hazvidi kurapwa nekupisa. 8.8 level thread dhayamita ye16MM kana pasi, 35 # tempering heat treatment, 16mm kana kupfuura, 45 # uye low carbon alloy steel tempering. 10.9 level ye medium-carbon alloy steel tempering Heat treatment 35Crmo 40Cr nezvimwewo.

Mabhaudhi ane simba guru anogona kusiyaniswa nemabhaudhi akafanana nezvinhu zvawo here?

Kazhinji kacho zvinokamurwa zvichienderana nehukuru hwesimba.

Bolt performance level 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 zvichingodaro pane magiredhi anopfuura gumi, ayo 8.8 zvichikwira mabhoti akagadzirwa nesimbi ine kabhoni shoma kana simbi ine kabhoni yepakati uye yakapiswa nekupisa (yakadzimwa, yakanyoroveswa), inozivikanwa semabhoti ane simba rakawanda, mamwe mabhoti anowanzozivikanwa. Kunyora mabhoti ane zvikamu zviviri zve digital composition, zvichiteerana, ndiko kuti, simba rekusimba rebhoti uye kukosha kwesimba reflexural.

Semuenzaniso, mabhoti egiredhi rekushanda ane 8.8, zvinoreva kuti:

1, bhaudhi rine simba rekudhonza re800MPa;

2, chiyero chesimba remuboti wezvinhu zvinoshandisa bhaudhi che0.8;

3, simba rekushandisa remabhoti rinosvika 800 × 0.8 = 640MPa nhanho yemabhoti anonyanya kushandiswa ane simba guru e8.8 ne10.9 level, mabhati akajairika anonyanya kushandiswa e4.8 level.
