Kodi muyezo woyeserera woyeserera ?

Musanatumize, Kuyika nokha kuyenera kuwunikira zotsatirazi malinga ndi miyezo yadziko komanso mafakitale. Okhawo omwe amadutsa amatha kumasulidwa:

1. Mawonekedwe ndi miyeso

– Ulusi uyenera kukhala wosaneneka, wopanda zilema kapena zotchinga; Mutu ndi mchira uyenera kukhala wopanda tanthauzo; pamwamba ziyenera kukhala zosalala, wopanda dzimbiri ndi zipsera.

– Gwiritsani ntchito zikwama za caliper, Mbale za mphete, ndi pign gauges kuti muwonetsetse pang'ono (mainchenti yakunja, utali, phula, ulusi ngodya). Kulekerera kumayenera kutsatira zojambula kapena GB / t 196/197 zofunikira.

2. Kuuma ndi kusamba kwa carburid

– Kuumitsa: Marteenitic Steel ≥100 HV; Kulimbana kokhazikika malinga ndi kalasi (20H / 25h, etc.).

– Kuzama kwa carburid: Malinga ndi GB / T 3098.7, Zitsanzo zitatu ziyenera kutengedwa kuchokera ku batch yomweyo, Ndipo mtengo woyeza uyenera kukhala pakati pa malire am'munsi komanso otsika a zolemba.

3. Kuphwanya Town

– Ikani Torque Pang'onopang'ono pa Cholinga Chodzipereka mpaka Frucrekwe, ndi kujambula mtengo wosweka; ziyenera kukhala ≥ mtengo wocheperako woperekedwa patebulo 5 ya RB / t 3098.21 (mwachitsanzo, St4.2-30h osachepera 3.9 N · m).

4. Screw-mu magwiridwe antchito

– Sakani mu gawo loyeserera la aluminium aloy (80-120 Hv) kapena pachabe chotsika (130-170 Hv) ya makulidwe ndi dzenje laling'ono mpaka ulusi wonse umatuluka; ulusi suyenera kuvula kapena kulanda, ndipo chimbudzi chimayenera kukhala chosalala komanso popanda kupanduka.

5. Tunsiile / Torsion Yosunga Mphamvu (Zowunikira zitsulo zodzikongoletsera)

– Pambuyo pokhazikitsa pa chiyeso choyenera cha aluminium, gwiritsani ntchito zomwe zimapangidwira ndi chiwongola dzanja cha torque; Kuyika sikuyenera kuzungulira; Pitilizani kutsatira mphamvu, ndipo imaganiziridwa kuti idadutsa (wokwanira) Ngati sichikutuluka pomwe mtengo wa mapangidwe umafika.

6. Kutetezedwa ndi Chitetezo cha Kuwonongeka (Ngati zingatheke)

– Kukula kwa makulidwe kumayesedwa malinga ndi GB / t 5267.1; Chiyeso cha saitral spray ≥ 48 h popanda dzimbiri chofiyira; kutsatira zomwe zidzakumane “Gawo lodula 1” zofunikira.

7. Kuyika ndikulemba

– Malinga ndi GB / T 90.2: Chikwama chamkati chimaphatikizapo satifiketi yogwirizana (kuphatikiza nambala ya batch, malaya, kulembana, ndi kuchuluka); Bokosi lakunja lidzakhazikika ndi chinyezi-chinyezi komanso zolembera, ndi limodzi ndi lipoti loyang'anira.

Zinthu zomwe zili pamwambazi ndi zoyeserera zoyeserera; Ngati kasitomala ali ndi zofunikira zapadera (monga moyo wogwedezeka, utoto wa torque, Rohs, Dfa), Mayeso ofananira amatha kuwonjezeredwa ndikuphatikizidwa mu mgwirizano wabwino.
