Zomangira zomata zokhotakhota zapamutu za Metric cross [Table 9]

Fikirani mwatsatanetsatane ndikumangitsa kodalirika ndi zomangira za Metric cross recessed countersunk mutu zomwe zimagwirizana ndi ASME B 18.6.5M - 2000 (R2010). Kaya zopangira matabwa kapena zomanga, zomangira izi zimapereka mayankho osunthika pazosowa zanu zosonkhana.

Chitsanzo:ASME B 18.6.5M

Tumizani Kufunsira

Mafotokozedwe Akatundu

Precision Tapping:ASME B 18.6.5M - 2000 (R2010) zomangira za Metric cross recessed countersunk head tapping kuchokera ku Table 9 zimatsimikizira kugogoda ndi ulusi wolondola. Mapangidwe awo amathandizira kuyika kosalala komanso kumangirira kotetezeka muzinthu zosiyanasiyana.

Countersinking yowonjezera:Zokhala ndi kapangidwe kamutu kowukira, zomangira izi zimapereka kuyika kwamadzi, kumachepetsa kutuluka kwa pamwamba ndikuwonetsetsa kuti ziwoneka bwino komanso zaukadaulo. Izi ndizothandiza makamaka pamapulogalamu omwe amafunikira kukongola.

Kumanga Kodalirika:Potsatira ASME B 18.6.5M - 2000 (R2010), zomangira izi zimapereka magwiridwe antchito odalirika. Kaya amagwiritsidwa ntchito popanga matabwa, zitsulo, kapena kumanga, amapereka zolumikizira zolimba, zotetezeka zomwe sizimatha kunyamula katundu ndi kugwedezeka kosiyanasiyana.

Ntchito Yonse:Zokwanira pama projekiti angapo, zomata za metric izi ndizokhazikika komanso zosinthika. Kuchokera pakupanga mipando mpaka kupanga makina, amapereka mayankho odalirika pamafakitale ndi ntchito zosiyanasiyana.

①, Zomangira zamutu zokhazikika Mitundu D, F, ndi zomata za T ziyenera kukhala ndi mawonekedwe amutu wa Style B. Mitu yokhazikika Mitundu ya AB, B, BF, ndi BT tapping screws iyenera kukhala ndi mawonekedwe a mutu wa Style A. Mapewa apansi pamutu ndi ovomerezeka pamtundu wa mutu wa Style B, ndipo miyeso ina yonse yamutu idzakhala yodziwika pamitundu yonse ya sitayilo A ndi Mtundu B.
②, muyezo wofananira wa ISO ndi ISO 7050.
