Waa maxay heerka imtixaanka ee gelitaanka gelitaanka ?

Ka hor inta aan la rarin, Xirmooyinka is-taajinta waa in ay maraan kormeerka soo socda si waafaqsan heerarka qaranka iyo hab-dhaqannada warshadaha. Kaliya kuwa ku gudba kormeerka ayaa la sii deyn karaa:

1. Muuqaalka iyo Cabirka

– Xadhigyadu waa in ay noqdaan, aan lahayn cillado ama burooyin; madaxa iyo dabada waa inay ahaadaan kuwo aan qalloocin; dusha sare waa inuu ahaadaa mid siman, miridhku iyo xagxag la'aan.

– Isticmaal qiyaasaha caliper, cabirrada giraanta, oo ku xidh cabbirada si aad si aan kala sooc lahayn u baadho cabbirrada ugu muhiimsan (dhexroorka dibadda, dhererka, garoonka, xagal dunta). Dulqaadyadu waa inay waafaqsan yihiin sawirada ama GB/T 196/197 shuruudaha.

2. Adag iyo Lakab Karbursan

– Adkaanshaha dusha sare: Birta Martensitic ≥300 HV; adkaanta xudunta loo xakameeyo iyadoo loo eegayo heerka shay (20H/25H, iwm.).

– Moolka lakabka kaarburized: Sida laga soo xigtay GB/T 3098.7, saddex shaybaar waa in laga soo qaadaa isla dufcaddii, iyo qiimaha la cabbiray waa in uu u dhexeeyaa xadka sare iyo hoose ee dukumentiyada habka.

3. Jebinta Torque

– Si tartiib ah u mari qulqulka qalabka loo qoondeeyay ilaa uu ka dillaaco, oo diwaangeli qiimaha torque-ga jabay; waa in ay ahaataa ≥ qiimaha ugu yar ee shaxda 5 heerka GB/T 3098.21 (tusaale., ST4.2-30H aan ka yarayn 3.9 N·m).

4. Waxqabadka isku-xidhka

– Ku marooji gelinta saxanka tijaabada ah ee daawaha aluminiumka (80-120 HV) ama birta kaarboon yar (130-170 HV) dhumucdiisuna waxay cayiman tahay iyo dhexroorka daloolka ilaa uu ka soo baxo dun dhammaystiran; dunta waa in aan la jeexin ama la jarjarin, iyo torque-gurgudka waa inuu ahaadaa mid siman oo aan ciriiri lahayn.

5. Xoog-hayntiisa Trsion/Torsion (ee birta is-taabacaadda)

– Ka dib markii la rakibo dul galka tijaabada aluminium ee caadiga ah, ku codso rarka hore ee la cayimay adigoo isticmaalaya wiish xoog leh; gelinta waa in aysan si wareeg ah u wareegin; sii wad adeegsiga xoogga ka bixista, waxaana loo tixgalinayaa in laga gudbay (u qalma) haddii aysan soo bixin marka qiimaha naqshadeynta la gaaro.

6. Dahaarka iyo Ilaalinta Daxalka (haddii ay khuseyso)

– Coating thickness shall be tested according to GB/T 5267.1; neutral salt spray test ≥ 48 h with no red rust; adhesion shall meet the “Cross-cut Grade 1” requirement.

7. Packaging and Labeling

– Sida laga soo xigtay GB/T 90.2: The inner bag shall include a certificate of conformity (including batch number, maaddo, specifications, and quantity); the outer box shall be affixed with moisture-proof and shock-proof labels, and accompanied by a shipping inspection report.

The above items are routine mandatory inspection contents; if the customer has special requirements (such as vibration life, torque attenuation, RoHS, DFAR), corresponding tests can be added and included in the quality agreement.
