Yiliphi indinganiso yokuhlola yokuzishaya ngokuthepha ?

Ngaphambi kokuthumela, Ukufakwa kokuzishaya kufanele kuhlolwe okulandelayo ngokuya ngamazinga kazwelonke nezimboni zezimboni. Yilabo kuphela abadlulisela ukuhlolwa kuphela:

1. Ukubukeka nobukhulu

– Imicu kumele ibe yinhle, Ngaphandle kwezici noma ama-burrs; ikhanda nomsila kufanele kube mahhala deformation; Ingaphezulu kumele libushelelezi, mahhala ukugqwala nokuklwebheka.

– Sebenzisa ama-caliper gauges, ring gauges, futhi ixhume ama-gauges ukuze uhlole ngezikhathi ezithile ubukhulu obukhulu (ububanzi obungaphandle, ubude, iphimbo, intambo angle). Ukubekezelela kufanele kuhambisane nemidwebo noma i-GB / T 196/197 Izidingo.

2. Ubulukhuni kanye nongqimba

– Ubulukhuni obungaphezulu: I-Martensitic Steel ≥300 HV; Ubulukhuni obuyisisekelo obulawulwa ngokuya ngebanga le-Material (20H / 25h, njll.).

– Ukujula kwesendlalelo: Ngokusho kwe-GB / T 3098.7, Amasampula amathathu kufanele athathwe kwi-batch efanayo, Futhi inani elilinganisiwe kufanele libe phakathi kwemikhawulo ephezulu nangaphansi yemibhalo yenqubo.

3. Ukwephula i-torque

– Faka isicelo se-torque kancane ku-adfren ezinikezele kuze kube ukuqhekeka, futhi urekhode inani le-torque ephula umthetho; Kufanele kube yinani eliphansi elinikezwe etafuleni 5 ye-GB / T ejwayelekile 3098.21 (e.g., ST4.2-30H hhayi ngaphansi 3.9 Ni).

4. Ukusebenza Kokusebenza

– Skena ukufaka ipuleti lokuhlola le-aluminium alloy (80-120 Hv) noma insimbi ephansi yekhabhoni (130-170 Hv) wobubanzi obucacisiwe kanye nobubanzi bomgodi kuze kube yilapho intambo eyodwa ephelele iyavela; Intambo akumele ihluthwe noma icindezelwe, Futhi i-torque yesikulufa kufanele ibusheleleke futhi ngaphandle kokubhalisa.

5. Amandla okugcina aseTensile / Torsion (ngokufakwa kwensimbi kokuzishaya)

– Ngemuva kokufaka kwi-Aluminium Test Block ejwayelekile, Faka isicelo samalayidi esichaziwe nge-torque wrench; Ukufakwa akufanele kujikeleze ngokujwayelekile; Qhubeka nokusebenzisa amandla okudonsa, futhi kubhekwa njengedlule (-nokwazi) Uma kungakhiphi lapho inani lokuklama lifinyelelwa.

6. Ukuvikelwa Nokuvulwa Kokugqwala (Uma kusebenza)

– Ukuqina okuhlanganayo kuzohlolwa ngokuya nge-GB / T 5267.1; I-Neutral Salt Spray Test ≥ 48 h ngaphandle kokugqwala okubomvu; ukunamathela kuzohlangana “Ibanga lokusika-ukusika 1” okudingekayo.

7. Ukupakishwa nokulebula

– Ngokusho kwe-GB / T 90.2: Isikhwama sangaphakathi sizofaka isitifiketi sokuvumelana (kufaka inombolo ye-batch, into uqobo lwayo, ukucacisa, nobungako); Ibhokisi langaphandle lizohambisana namalebula woMswakama-Ubufakazi Bomsindo, futhi kuhambisana nombiko wokuhlola wokuthumela.

Izinto ezingenhla ziyinto ejwayelekile yokuhlola ukuqinisekiswa; Uma ikhasimende linezidingo ezikhethekile (njengempilo yokudlidliza, I-Torque Attenuation, Rohs, Idlelo), Ukuhlolwa okuhambisanayo kungangezwa futhi kufakwe esivumelwaneni sekhwalithi.
