Flat musoro chiboorera muswe self drilling screw 410 Stainless simbi countersunk self tapping self drilling screw stainless steel dovetail screw

Kana iwe uchigona kutanga wanzwisisa ma mechanic properties ye screws paunenge uchizvishandisa, saka unogona kuzvishandisa zviri nani. Mhando dzakasiyana dzema screws dzine akasiyana mechanical properties, uye akasiyana mechanical zvivakwa zvinoguma nezviitiko zvakasiyana umo ma screws anoshandiswa.
1, Self tapping screws: mechanic kuita zvinodiwa
1. Kuoma kwemoyo: kukosha kwehuwandu HRC28-38. Paunenge uchiyedza, tora chikamu 1-2 nguva yezita dhayamita kubva kumuswe. Kana urefu hwezita hwakanyanya kupfupika, hunogona kuiswa pekutanga uye ipapo kuoma kunogona kuyerwa.
2. Kuoma kwechiso: Standard MIN HV450.
3. Carbonized layer: Standard 4 # -6 #: 0.05-0.18mm, 8 # -12 #: 0.10-0.23mm, 14 #: 0.13-0.28mm. Chinangwa chikuru che carburization ndechekuwedzera kuoma kwepamusoro uye kuve nechokwadi chekusimba kwemeno. Kana iyo decarburization yakadzika zvakanyanya uye iyo carburization haina kukwana, simba remeno haringasviki zvinodiwa, izvo zvinoreva kuti mazino achakuvadzwa panguva yescrew mukuedzwa.
4. Torque: Standard tsanangudzo 4 # 5 # 6 # 7 # 8 # 10 # 12 # 14 # A mazino 14212835455696145AB mazino 142128354565102165.
5. Kukurura mukuyedza: Kukurura siruu ye self tapping mundiro yesimbi ine maburi ebvunzo akachengetwa. Iyo self taper screw inofanira kuumba shinda inoenderana mutest plate, uye shinda yescrew pachayo haifanire kukanganiswa kana kukuvadzwa kusvika tambo yekugumisira yanyatsopfuura nemutest plate. Iyo screw in test inongoshanda kune self tapping screws emhando AB, B, BP, zvichingodaro. Zvinoenderana nemirairo yeIFI, ndiro yekuyedza inofanira kugadzirwa kubva kusimbi yakaoma yakaderera-kabhoni inotonhora-yakakungurutswa simbi ine Rockwell kuomarara kwe70-85HRB. Izvo zvakajairwa zvemahwendefa esimbi, kusanganisira ukobvu, zvinoratidzwa mutafura iri pazasi. Iwo maburi ebvunzo anofanirwa kubaiwa kana kudhiriwa, nekushivirira kwe ± 0.025mm kune yakatsanangurwa dhayamita yezita (ona tafura pazasi). Tsanangudzo 6 # 7 # 8 # 10 # 12 # 1/4 bvunzo ndiro ukobvu (mm) 1.85-1.953.12-3.234.68-4.84 aperture (mm) ± 0.0252.953.263.454.044.765.50

2、 Wall panel mbambo
1. Kuoma kwemoyo: chiyero: HRC24-45.
2. Kuoma kwechiso: Standard: HV600-800.
3. Carbonized layer: 4 # -6 # 0.05-0.18mm, 8 # -12 # 0.10-0.23, 14 # 0.13-0.28.
4. Kupeta dhigirii: inodiwa kuva 150-450
5. Kuedza kupfapfaidza munyu: kazhinji MIN 48 maawa.
6. Torque: Tsanangudzo 6 # 7 # 8 # 10 # Torque 21283558.
3, Drill muswe sikuruu
1. Kuoma kwemoyo: Standard: HRC32-40. Zvigadzirwa zvekambani yedu zvakaedzwa kuti zvine HRC31.7-39.0.
2. Kuoma kwechiso: Standard: HV600-700. Chigadzirwa chekambani yedu chakaedzwa kuve chakapoteredza HV620.
3. Permeation layer: 4 # -6 #: 0.05-0.18mm 8 # -12 #: 0.10-0.23mm
