Yintoni le nqanaba lokuvavanya lokuzifaka ?

Ngaphambi kokuba kuthunyelwe, Ukufakelwa kokuzifaka. Kuphela ngabo baphumelela uvavanyo anokukhululwa:

1. Imbonakalo kunye nobungakanani

– Imisonto kufuneka ibe ye-tict, ngaphandle kweziphene okanye burrs; intloko kunye nomsila kufuneka zingabikho deformation; umphezulu kufuneka ube mpuluswa, engenamhlwa nemikrwelo.

– Sebenzisa i-caliper gauges, iigeji zeringi, kunye neegeji zeplagi ukuhlola ngokungenamkhethe imilinganiselo engundoqo (idayamitha yangaphandle, ubude, isandi, i-engile yomsonto). Ukunyamezelana kufuneka kuhambelane nemizobo okanye i-GB/T 196/197 iimfuno.

2. Ukuqina kunye neCarburized Layer

– Ukuqina komphezulu: Intsimbi yeMartensitic ≥300 HV; core ubulukhuni elawulwa ngokwebakala eziphathekayo (20H/25H, njl.).

– Carburized umaleko ubunzulu: Ngokutsho kwe-GB/T 3098.7, iisampulu ezintathu kufuneka zithathwe kwibhetshi enye, kwaye ixabiso elilinganisiweyo kufuneka libe phakathi kwemida ephezulu nangaphantsi yamaxwebhu enkqubo.

3. Ukuqhawula iTorque

– Faka itorque ngokucothayo kwindawo ezinikeleyo de waphuke, kwaye urekhode ixabiso letorque yokwaphula; kufuneka ibe ≥ elona xabiso liphantsi linikwe kwiTheyibhile 5 yomgangatho we-GB/T 3098.21 (umz., ST4.2-30H hayi ngaphantsi kwe 3.9 N·m).

4. Ukusebenza kweScrew-in

– Screw ufake kwipleyiti yovavanyo yealluminiyam (80-120 HV) okanye intsimbi yekhabhoni ephantsi (130-170 HV) ubukhulu obuchaziweyo kunye nedayamitha yomngxuma kude kuvele umsonto omnye opheleleyo; umsonto mawungaqhawuki okanye uqhawulwe, kunye ne-screwing torque kufuneka ihambe kakuhle kwaye ingabi ne-jamming.

5. I-Tensile/Torsion Retention Force (ukufakwa kwentsimbi yokuzibetha)

– Emva kofakelo kwibhloko yovavanyo lwe-aluminiyam eqhelekileyo, sebenzisa ukulayisha kwangaphambili okukhankanyiweyo kunye ne-torque wrench; isifakelo akufuneki sijikelezise ngokujikelezayo; qhubeka usebenzisa amandla okutsala, kwaye ithathwa njengepasisiwe (ufanelekile) ukuba ayikhupheli xa ixabiso loyilo lifikelelwe.

6. Ukugquma kunye nokuKhuselwa kokuMhlwa (ukuba kuyangena)

– Ubukhulu bokugquma buya kuvavanywa ngokwe-GB/T 5267.1; uvavanyo lokutshiza ityuwa engathathi hlangothi ≥ 48 h ngaphandle komhlwa obomvu; ukunamathela kuya kuhlangana “IBanga loku-1 elinqamlezileyo” imfuneko.

7. UkuPakisha kunye nokuFakwa kweelebhile

– Ngokutsho kwe-GB/T 90.2: Isingxobo sangaphakathi siya kubandakanya isatifikethi sokuthotyelwa (kuquka inombolo yebhetshi, impahla, iinkcukacha, kunye nobungakanani); ibhokisi yangaphandle iya kuncanyathiselwa ngeeleyibhile ezikhusela ukufuma kunye nezothusayo, kunye nokukhatshwa yingxelo yokuhlolwa kwenqanawa.

Ezi zinto zingasentla ziziqulatho zokuhlolwa okunyanzelekileyo; ukuba umthengi uneemfuno ezizodwa (njengobomi bokungcangcazela, ukuthotywa kwetorque, RoHS, DFAR), iimvavanyo ezihambelanayo zingongezwa kwaye zifakwe kwisivumelwano somgangatho.
