Kuongororwa kweroriU-mabhaudhiinofanirwa kuvhara zviyero, zvivakwa zvezvinhu, mashandiro emuchina, uye zvimwe zvinhu. Iwo chaiwo mastandard ndeaya anotevera:
1. Dimensional Accuracy Inspection,
Zviyero Zvinhu: Hurefu, hupamhi, ukobvu, kurongeka kweshinda, nezvimwewo, kushandisa calipers, micrometers, kana mamwe maturusi echokwadi kuti ave nechokwadi chekutevedzera zvinodiwa nedhizaini.
Zvinodiwa Zvekushivirira: Kana uchitarisa shinda inokwana nego/no-go geji, geji rekuti “enda” rinofanirwa kupinda mukati zvakanaka, nepo geji rekuti “hapana-kuenda” harifanire kudarika kutendeuka kwe2.
2. Surface Quality Inspection,
Visual Inspection: Nzvimbo yacho inofanira kunge yakatsetseka, isina ngura, yakatsemuka, makwara, kana kumwe kuremara (yakatariswa nekuona kana tactile bvunzo).
Kuongorora Kwekuputira: Iyo yekuvharisa inofanira kunge yakafanana, ine ukobvu hwekusangana mwero (semuenzaniso, munyu wekupfapfaidza bvunzo yekuongorora kusaita ngura).
3. Material & Chemical Maumbirwo
Material Verification: Kuongororwa kwemakemikari kunofanirwa kuenderana nekabhoni simbi (semuenzaniso, Q235) kana simbi isina tsvina (semuenzaniso, 304) zviyero.
Giredhi Kumaka : Carbon simbi mabhaudhi anofanirwa kunge aine simba giredhi mamaki (eg, 8.8), nepo Stainless simbi ichifanirwa kuratidza zvinhu macode.
4. Mechanical Performance Testing,
Tensile Strength: Yakasimbiswa kuburikidza nekuyedzwa kwekumanikidza, kuve nechokwadi chekuti mafracture anoitika mune yakarukwa kana isina-shinda shank.
Kuomarara Kuyedzwa: Kuyerwa uchishandisa kuomarara tester kuti ive nechokwadi chekutevedzera zvinodikanwa zvekurapa kupisa.
Torque & Preload Testing: Simbisa torque coefficient kuti uve nechokwadi chekumisikidzwa.
5. Maitiro & Defect Detection,
Cold Heading & Thread Rolling: Tarisa uone chamfering chaiyo, burr-isina mipendero, uye hapana zviratidzo zvekukuvadza mold.
Magnetic Particle Inspection (MPI): Inoshandiswa kuona kutsemuka kwemukati, inclusions, kana humwe hurema hwakavanzwa.
6. Maitiro & Certification,
Mitemo Inoshanda: Tarisa kuQC/T 517-1999 (U-mabhaudhiyemotokari mashizha zvitubu) kana JB/ZQ 4321-97.
Packaging & Marking: Packaging inofanira kuratidza mazinga enyika; misoro yebhaudhi inofanira kutwasuka, uye shinda dzinofanira kunge dzakachena uye dzisina zvinosvibisa.
Mamwe Manotsi:
Kuti uongorore batch, mimwe miedzo yakadai sehupenyu hwekuneta uye hydrogen embrittlement senitivity inogona kudiwa.
Kuongorora kunowanzotora 3-5 mazuva ekushanda, nenyaya dzakaomarara dzichienda kumazuva 7-10.
