Makulidwe a Undercut 82-deg Flat Countersunk Head Screws (ASTM F837 F468)

Pezani zolondola komanso zodalirika ndi Undercut 82-degree Flat Countersunk Head Machine Screws, kukwaniritsa miyezo ya ASME B 18.6.3 - 2013. Kaya mumagalimoto, mlengalenga, kapena makina, zomangira izi zimapereka magwiridwe antchito komanso kumamatira kotetezeka.

Chitsanzo:ASME B 18.6.3

Tumizani Kufunsira

Mafotokozedwe Akatundu

Precision Engineering:Undercut 82-degree Flat Countersunk Head Machine Screws amatsatira zomwe zafotokozedwa mu ASME B 18.6.3 - 2013, kuwonetsetsa kukula kwake ndi magwiridwe antchito osasinthika. Mogwirizana ndi miyezo ya ASTM F837 ndi F468, zomangira izi zimatsimikizira kudalirika pamapulogalamu omwe akufuna.

Undercut Design:Zomangira zamkati mwa zomangira izi zimapereka kukwanira bwino zikayikidwa, kumachepetsa kutulutsa kwa mawonekedwe owoneka bwino komanso owoneka bwino. Kapangidwe kameneka kamapangitsanso luso la screw kuti ligawire mphamvu zonyamula katundu mofanana, zomwe zimathandizira kukhazikika komanso kudalirika.

Flat Countersunk Head:Zopangidwa ndi mutu wathyathyathya wothira, zomangira izi zimapanga malo osungunuka zikaikidwa, kuchepetsa chiwopsezo cha kugwedezeka ndikumaliza koyera. Mapangidwe a mutu wathyathyathya amapereka malo okwanira kuti athe kunyamula katundu, kupititsa patsogolo mphamvu zonse za mgwirizano womangirira.

Ntchito Zosiyanasiyana:Undercut 82-degree Flat Countersunk Head Machine Screws ndi yoyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza magalimoto, mlengalenga, ndi makina. Miyezo yawo yolondola komanso kapangidwe kake kolimba zimawapangitsa kukhala abwino pantchito zomangirira pomwe kudalirika ndikofunikira.

②,Zingwe zazitalizi ndi zazifupizi zimakhala ndi mitu yodukaduka.
④, Kutalikirana kwa thupi pa zomangira zamakina zomwe zili ndi mitu ina kupatula mitu yochepetsera sikuyenera kukhala kocheperako ulusi wa Class 2A ulusi wocheperako kapena kupitilira kukula kwake kwakukulu kwa ulusi.
⑤, Kutalikirana kwa Ulusi Wamakina
1) Makulidwe No.5 ndi ang'onoang'ono.
Zilungo zautali wofanana ndi ma diameter atatu ndi zazifupi ziyenera kukhala ndi ulusi wathunthu wofikira mkati mwa nsonga imodzi (ulusi) wa
kunyamula pamwamba pa mutu, kapena pafupi, ngati n'kotheka. Kutalika kwadzina kopitilira ma diameter atatu, mpaka kuphatikiza 1-1/8 mkati
ulusi wathunthu womwe umafikira mkati mwa mizere iwiri (ulusi) wa pamwamba pamutu, kapena kuyandikira, ngati n'kotheka. Zopangira zazitali
