Umxholo wokuhlolwa kweefasteners

Iziqhoboshi, ezikwabizwa ngokuba ziindawo eziqhelekileyo kwimarike, ligama eliqhelekileyo lohlobo lwamalungu oomatshini asetyenziselwa ukudibanisa ngokukhuselekileyo amalungu amabini okanye ngaphezulu (okanye amacandelo) ngokupheleleyo. Zibizwa ngokuba "ziimitha zamashishini" kwaye zinezicelo ezibanzi kwimimandla efana noomatshini, izixhobo, izithuthi, iinqanawa, oololiwe, iibhulorho, izakhiwo, izakhiwo, izixhobo, izixhobo, izixhobo kunye nezibonelelo.

Izinto zokuhlola ukusebenza kweziqhoboshi zibandakanya: ubungakanani, ukwakheka kweekhemikhali, uvavanyo olungonakalisi, iipropathi zoomatshini ezibandakanya uqhagamshelo lwebholiti ye-torsion, ukuqinisa amandla e-axial, ukuqina (amandla esivuno, amandla okuqina), ubulukhuni, kunye novavanyo lweepropathi zoomatshini kwiziqhoboshi zentsimbi.

Amabanga okwenziwa komsebenzi weiibholiti zolwakhiwo lwentsimbidibanisa ngo 4.6, 4.8, 6.8, 8.8,10.9, 12.9, njl njl.iibholiti eziphezulu, kwaye ezinye zidla ngokubizwa ngokuba ziibholiti eziqhelekileyo

Umxholo wokuhlolwa kweefasteners

1. Ubungakanani bembonakalo: i-thread go/no go gauge, uburhabaxa bomphezulu, imilinganiselo eyahlukeneyo efana nedayamitha enkulu, idiameter yepitch, idiameter encinci, i-profile angle, pitch, njl.

2. Uvavanyo lokusebenza koomatshini: uvavanyo lokuqina, uvavanyo lokubamba, uvavanyo lokuqina, uvavanyo lwempembelelo, uvavanyo lomthwalo we-wedge, uvavanyo lokucheba, uvavanyo lokudinwa, ukutshixa ukusebenza, i-torque coefficient, i-axial force, i-coefficient ye-friction, i-anti slip coefficient, uvavanyo lokuqina, ukuqina kwe-gasket, uvavanyo lokuqina, uvavanyo lwe-hydrogen, njl.

3. Uhlalutyo lokubunjwa kweekhemikhali: uhlalutyo lwe-fastener chemical composition, i-fastener metal material grade identification grade, njl.

4. Uhlalutyo lwe-metallographic: i-microstructure, ubunzulu be-decarburization layer, ubunzulu be-carburization layer, ukulinganisa ubungakanani bengqolowa, umxholo wokubandakanywa, i-macrostructure, njl.

5. Uhlalutyo lokungaphumeleli: uhlalutyo lwe-crack, uhlalutyo lwe-fracture, uhlalutyo lwe-fracture, njl.

6. Uvavanyo lokumelana ne-Corrosion: uvavanyo lwe-salt spray olungathathi hlangothi (NSS), uvavanyo lwe-acetate spray (AASS), uvavanyo olukhawulezayo lwe-acetate spray (CASS)
