Kodi Mitundu Yonseyi ya Ulusi Ingathe Kukonzedwa Ndi Pipe Thread Lathes?

Makasitomala aku Turkey omwe adagula athuCNC chitoliro ulusi lathesanathe kukwaniritsa zofunikira zawo pakukonza ulusi chifukwa adasankha dongosolo la CNC la Fanuc 5. Choncho, zimaganiziridwa kuti zilowe m'malo mwa dongosolo kachiwiri, zomwe zimabweretsa vuto lalikulu la ntchito kwa kasitomala. Kukonzekera kwa ulusi wosiyanasiyana kumadalira kwathunthuCNC makina zida, ndi kusankha kwa CNC dongosolo n'kofunikanso makamaka.

Kodi pali mitundu ingati ya ulusi?

NPT ndiye chidule cha National (American)Pipe Ulusi, yomwe ndi ya American standard 60 -degree tapered pipe thread ndipo imagwiritsidwa ntchito ku North America. Miyezo ya dziko imapezeka mu standard standard GB/T12716-1991.

PT ndiye chidule cha Pipe Thread. Ndi ulusi wa chitoliro wosindikizidwa wa digirii 55. Ndi a banja la Wyeth ulusi ndipo amagwiritsidwa ntchito kwambiri ku Europe ndi Commonwealth of Nations. Nthawi zambiri amagwiritsidwa ntchito m'madzi ndi gasimafakitale a pipe, wojambulayo amatchulidwa kuti 1:16. Miyezo ya dziko imapezeka mu GB/T7306-2000.

G ndi ulusi wosasindikiza wa digirii 55, womwe ndi wa banja la Wyeth. Chizindikiro G chikuyimira ulusi wozungulira. Miyezo ya dziko imapezeka mu GB/T7307-2001.

Kuonjezera apo, zizindikiro za 1/4, 1/2, 1/8 mu ulusi zimatanthawuza kukula kwa ulusi, ndipo unit ndi inchi. Olowera mkati nthawi zambiri amagwiritsa ntchito mfundo kutengera kukula kwa ulusi, inchi imodzi imafanana ndi mfundo 8, 1/4 inchi ikufanana ndi mfundo ziwiri, ndi zina zotero. G ndi dzina lambiri laulusi wa bomba(Guana). Kugawanika kwa madigiri 55 ndi 60 ndi ntchito, yomwe imadziwika kuti bwalo la chitoliro. Ndiye kuti, ulusi umakonzedwa ndi cylindrical surface.

ZG imadziwika kutipayipi koloko, ndiko kuti, ulusi umakonzedwa ndi conical pamwamba. Madzi ambirimapaipi olowazili ngati izi. Muyezo wapadziko lonse walembedwa kuti Rc metric thread kufotokoza ndi phula, ndipo ulusi waku America ndi waku Britain umawonetsedwa ndi kuchuluka kwa ulusi pa inchi. Ndilo kusiyana kwakukulu pakati pawo. Metric ulusi ndi 60 digiri equilateral mbiri, British ulusi ndi isosceles 55 digiri mbiri, ndi American ulusi ndi 60 madigiri.

Ma metric unit amagwiritsidwa ntchito ngati ulusi wa metric, ndipo mayunitsi achifumu amagwiritsidwa ntchito ngati ulusi waku US ndi Britain.
