Okuqukethwe kokuhlolwa kwezinsimbi

Izixhumi, ezaziwa nangokuthi izingxenye ezijwayelekile emakethe, ziyitemu elivamile lohlobo lwezingxenye ezisetshenziswayo ukuxhuma ngokuvikelekile izingxenye ezimbili noma ngaphezulu (noma izingxenye) zibe zizonke. Abizwa ngokuthi “amamitha ezimboni” futhi anezicelo ezibanzi emikhakheni efana nemishini, okokusebenza, izimoto, imikhumbi, izitimela, amabhuloho, izakhiwo, izakhiwo, amathuluzi, amathuluzi, amathuluzi, kanye nempahla.

Izinto zokuhlola ukusebenza kwezinsimbi zifaka: usayizi, ukwakheka kwamakhemikhali, ukuhlolwa okungabhubhisi, izakhiwo zemishini ezifaka i-bolt coefficient of torsion, ukuqinisa amandla e-axial, ukuqina (amandla okukhiqiza, amandla aqinile), ubulukhuni, nokuhlolwa kwezakhiwo zemishini zezinsimbi zesakhiwo sensimbi.

Amabanga okusebenza weamabhawodi esakhiwo sensimbijoyina 4.6, 4.8, 6.8, 8.8,10.9, 12.9, njll. Amabhawodi ebanga lesi-8.8 nangaphezulu asekelwa insimbi ene-carbon alloy ephansi noma insimbi ye-carbon medium and heat treatment, ngokuvamile ebizwa ngokuthi.amabhawodi aphezulu, kanti ezinye zivame ukubizwa ngokuthi amabhawudi ajwayelekile

Okuqukethwe kokuhlolwa kwezinsimbi

1. Ubukhulu bokubukeka: i-thread go/no go gauge, ukuhwaqeka kwendawo, ubukhulu obuhlukahlukene obufana nobubanzi obukhulu, ububanzi bephimbo, ububanzi obuncane, i-engeli yephrofayela, ukuphakama, njll.

2. Ukuhlolwa kokusebenza kwemishini: ukuhlolwa okuqinile, ukuhlolwa kokubamba, ukuhlolwa kokuqina, ukuhlolwa kokushisa kabusha, ukuhlolwa komthelela, ukuhlolwa komthwalo we-wedge, ukuhlolwa kwe-shear, ukuhlolwa kokukhathala, ukusebenza kokukhiya, i-torque coefficient, ukuqinisa amandla e-axial, i-friction coefficient, i-anti slip coefficient, ukuhlolwa kwe-screwability, ukunwebeka kwe-gasket, ukuhlolwa kokuqina, ukuhlolwa kwe-hydrogen embrittlement, njll.

3. Ukuhlaziywa kokwakheka kwamakhemikhali: ukuhlaziya ukwakheka kwamakhemikhali okuyisiqinisi, ukuhlonza ibanga lensimbi yesibambiso, njll.

4. Ukuhlaziywa kwe-Metallographic: i-microstructure, ukujula kwesendlalelo se-decarburization, ukujula kwesendlalelo se-carburization, isilinganiso sosayizi wokusanhlamvu, okuqukethwe okufakiwe, i-macrostructure, njll.

5. Ukuhlaziywa kokwehluleka: ukuhlaziywa kokuqhekeka, ukuhlaziywa kwe-fracture, ukuhlaziywa kwe-fracture, njll.

6. Ukuhlolwa kokumelana nokugqwala: ukuhlolwa kwesifutho sikasawoti esingathathi hlangothi (NSS), ukuhlolwa kwe-acetate spray (AASS), ukuhlolwa kwe-acetate spray okusheshisiwe (CASS)
