Intloko ecaba yoqhelisa umsila self-drilling screw 410 steel stainless countersunk self tapping self-drilling screw

Ukuba unokuqala ukuqonda iimpawu zomatshini we-screws xa uzisebenzisa, ngoko unokuzisebenzisa kakuhle. Iindidi ezahlukeneyo ze-screws zineempawu ezahlukeneyo zoomatshini, kwaye iipropathi ezahlukeneyo zomatshini zikhokelela kwizihlandlo ezahlukeneyo apho kusetyenziswa izikrufu.
1, Izikrufu zokuzicofa: iimfuno zokusebenza koomatshini
1. Ubulukhuni bentliziyo: ixabiso eliqhelekileyo HRC28-38. Xa uvavanya, thabatha icandelo le-1-2 ngamaxesha omlinganiselo oqhelekileyo ukusuka kumsila. Ukuba ubude begama bufutshane kakhulu, bunokuthi bufakwe kuqala kwaye emva koko ubunzima bunokulinganiswa.
2. Ukuqina komphezulu: MIN HV450 eqhelekileyo.
3. Umaleko weCarbonized: Standard 4 # -6 #: 0.05-0.18mm, 8 # -12 #: 0.10-0.23mm, 14 #: 0.13-0.28mm. Eyona njongo iphambili ye-carburization kukuphucula ukuqina komphezulu kunye nokuqinisekisa ukomelela kwamazinyo. Ukuba i-decarburization inzulu kakhulu kwaye i-carburization ayanelanga, amandla amazinyo akayi kuhlangabezana neemfuno, oku kuthetha ukuba amazinyo aya konakala ngexesha lokuvavanya.
4. Torque: Iimpawu eziqhelekileyo 4 # 5 # 6 # 7 # 8 # 10 # 12 # 14 # Amazinyo 14212835455696145AB amazinyo 142128354565102165.
5. Screw kuvavanyo: Screw the self tapping screw kwipleyiti yentsimbi enemingxuma yovavanyo ebekelwe bucala. I-self taper screw kufuneka yenze intambo ehambelanayo kwipleyiti yovavanyo, kwaye umsonto wesikrufu ngokwawo akufuneki ukhubazeke okanye wonakaliswe de umsonto wetaper ugqithe ngokupheleleyo kwipleyiti yovavanyo. Isikrufu kuvavanyo sisebenza kuphela kwi-self tapping screws zodidi lwe-AB, B, BP, njl. Ngokwemigaqo ye-IFI, ipleyiti yovavanyo kufuneka ilungiswe ukusuka kwintsimbi epholileyo ephantsi kwekhabhoni epholileyo enobulukhuni be-Rockwell ye-70-85HRB. Imilinganiselo esemgangathweni yeepleyiti zetsimbi, kubandakanywa ubukhulu, iboniswe kwitheyibhile engezantsi. Imingxunya yovavanyo kufuneka ibethelwe ngenqindi okanye yombiwe, ngonyamezelo lwe-± 0.025mm kububanzi obuchaziweyo obuchaziweyo (jonga kwitheyibhile engezantsi). Inkcazo 6 # 7 # 8 # 10 # 12 # 1/4 ubukhulu bepleyiti yovavanyo (mm) 1.85-1.953.12-3.234.68-4.84 ukuvuleka (mm) ± 0.0252.953.263.454.044.765.50.
2. Izikhonkwane zephaneli yodonga
1. Ubulukhuni bentliziyo: umgangatho: HRC24-45.
2. Ukuqina komphezulu: Umgangatho: HV600-800.
3. Umaleko weCarbonized: 4 # -6 # 0.05-0.18mm, 8 # -12 # 0.10-0.23, 14 # 0.13-0.28.
4. Idigri yokugoba: efunekayo ukuba ibe yi-150-450
5. Uvavanyo lwesitshizi setyuwa: ngokuqhelekileyo MIN 48 iiyure.
6. Torque: Inkcazo 6 # 7 # 8 # 10 # Torque 21283558.
3. Gcoba isikrufu somsila
1. Ukuqina kwentliziyo: Umgangatho: HRC32-40. Iimveliso zenkampani yethu ziye zavavanywa ukuba zine-HRC31.7-39.0.
2. Ukuqina komphezulu: Umgangatho: HV600-700. Imveliso yenkampani yethu ivavanyiwe ukuba ijikeleze i-HV620.
3. Umaleko wePermeation: 4 # -6 #: 0.05-0.18mm 8 # -12 #: 0.10-0.23mm
