Zigawo za Rivet, Rivet Shank, zigawo za rivet

Chipilala cha rivet chili ngati maziko onyamula katundu wa zigawo zonse za rivet. Chipilala chilichonse, kaya cholimba, chakhungu, cha semi-tubular kapena chomangidwa mozungulira, chimamangidwa mozungulira chipilalacho komanso zigawo zina zowonjezera za rivet zomwe zimakwaniritsa ntchito yomangirira ndi kutseka.

 1.1 Rivet Shank: Thupi Lonyamula Katundu Wapakati

Chigoba cha rivet chimatanthauza shaft yayikulu yozungulira yomwe imadutsa m'mabowo obowoledwa kale a zida zogwirira ntchito zodzaza, kudulidwa kwa bearing, kupsinjika ndi kugwedezeka panthawi yonse ya moyo wa cholumikizira. Mafotokozedwe ake atatu ofunikira amatsimikizira mwachindunji magwiridwe antchito a rivet:

Chimake cha Shank: Kukula kokhazikika kumayambira pa 2.4mm mpaka 12mm kuti zigwiritsidwe ntchito m'mafakitale. Zimake zazing'ono zimapanga mabowo omasuka komanso kulimba kofooka.

Kutalika kwa Chingwe (Kutalika Koyenera kwa Chingwe): Gawo logwiritsidwa ntchito la chingwe lomwe limagwirizana ndi makulidwe onse a zinthu zolumikizidwa. Kusankha chingwe chogwira chosakwanira sikuthandiza kupanga babu lonse lakumbuyo; kugwira kwambiri kumabweretsa kusintha kosafanana ndi kulumikizana kosasunthika pansi pa katundu woyenda.

Zipangizo Zopangira Shank & Coating: Zipangizo zodziwika bwino zimaphatikizapo aluminiyamu, chitsulo cha carbon, chitsulo chosapanga dzimbiri cha 304/316, mkuwa ndi mkuwa. Zinc plating, galvanization kapena passivation coating zimagwiritsidwa ntchito pamwamba pa shank kuti ziletse oxidation ndi galvanic dzimbiri pakati pa mapanelo achitsulo osiyana.

1.2 Zigawo Zoyambira Zothandizira Rivet Zophatikizidwa ndi Shank

1.2.1 Mutu Wozungulira

Mutu umapereka malo okulirapo oti uzitha kufalitsa mphamvu yolumikizirana bwino pamwamba pa gulu lakutsogolo, zomwe zimathandiza kuti mutuwo usakokedwe. Mitundu ya mitu yomwe imagwiritsidwa ntchito m'makampani ndi iyi:

• Mutu wa dome: Msonkhano wonse, malo akuluakulu olumikizirana, omwe amagwiritsidwa ntchito kwambiri pa makabati achitsulo ndi mafelemu a zida
• Mutu waukulu wa flange: Wa magawo owonda komanso ofooka monga mapepala apulasitiki ndi mapanelo a aluminiyamu
• Mutu wa Countersunk: Chofunikira pakumaliza pamwamba pa countersunk, chomwe chimagwiritsidwa ntchito pa mapanelo a thupi la galimoto ndi zida zamlengalenga
• Mutu waung'ono wosalala: Kuyika pang'ono kwa malo opapatiza komanso nyumba zazing'ono zamagetsi

1.2.2 Gawo la Mchira Wosinthika wa Rivet Shank

Ma rivets osawoneka bwino: Mchira wa shank wopanda kanthu umagwa ndipo mabaluni amalowa mu loko ya babu pamene mandrel imadutsa, ndikupanga nangula yakumbuyo yokhazikika popanda kufunikira kulowa kumbuyo kwa msonkhano.1.2.3 Mandrel

Mandrel ndi pini yapadera yachitsulo yomwe imadutsa mu shank ya rivet yopanda kanthu, gawo lofunika kwambiri la rivet lokhalo la pop/blind rivets.

1.2.4 Kola Yotsukira ndi Kutseka Yotsekera (Zida Zapadera za Rivet)

Pa ma rivets osalowa madzi ndi ma rivets omangidwa ndi kugwedezeka kwambiri, zigawo zina za rivets zimagwirizanitsidwa ndi shank:

l Chotsukira chotseka cha rabara/nayiloni: Chimagwirizana pakati pa mutu wa rivet ndi gulu kuti chilepheretse madzi, fumbi ndi mpweya kulowa m'malo otchingira akunja ndi amagetsi.

l Kolala yokhoma yachitsulo: Imagwiritsidwa ntchito pa ma rivets okhala ndi mphete ya Huck, imatsekeredwa pa groove yopindika kuti ichotse kumasuka chifukwa cha kugwedezeka kosalekeza kwa makina (magalimoto, makina olemera, zida za sitima)

2: Kugawa Zigawo za Rivet

Zigawo za rivet zimagawidwa m'magulu motsatira kapangidwe ka rivet, chifukwa gulu lililonse lili ndi mawonekedwe osiyana a shank ndi zigawo zothandizira.

2.1 Zigawo za Rivet za Chidutswa Chimodzi (Thupi Lolimba, Chigawo Chimodzi Chophatikizana cha Shank)

Ma rivets awa ali ndi zigawo ziwiri zokha za rivet: mutu wopangidwa + shank yolimba yokhazikika, palibe mandrel yamkati yosiyana. Kukhazikitsa kumafuna mwayi wopita mbali zonse ziwiri za workpiece kuti usinthe mchira wa shank.

2.2 Zigawo ziwiri za Rivet Blind (Hollow Shank + Separate Mandrel)

Mtundu wa rivet womwe umagwiritsidwa ntchito kwambiri popangira gulu la mbali imodzi, umagawidwa m'magawo awiri odziyimira pawokha: chipolopolo cha rivet (chipolopolo cha rivet chopanda kanthu) ndi pini ya mandrel. Magulu ang'onoang'ono kutengera ntchito ya shank:

1. Ma rivets akhungu otseguka

l Kusweka kwa zigawo za rivet: Mutu wa Flange + shank yosalala yopanda kanthu + mandrel yachitsulo

1. Ma rivets akhungu otsekedwa kumapeto

l Kusweka kwa zigawo za Rivet: Mutu waukulu wa flange + shank yotsekedwa bwino + mandrel yolimbana ndi dzimbiri

1. Ma rivets a babu okhala ndi zingwe zambiri

l Kusweka kwa zigawo za Rivet: Mutu waukulu wa flange + shank yowonjezereka m'mimba mwake yosinthika + mandrel yolimba kwambiri

2.3 Machitidwe a Rivet a Zinthu Zambiri

Ma rivets olimba osagwedezeka omwe amapangidwa ndi zigawo zitatu kapena zingapo za rivets kupitirira tsinde la maziko:

• Ma riveti a Huck okhala ndi mphete: Rivet sleeve (shank) + serrated mandrel + steel lock collar; shank ili ndi mizere yozungulira yomwe imalumikizana ndi kolala pambuyo poti mandrel atuluke.
• Ma riveti okhala ndi ma multi-grip atatu: Chigoba cholimba cha khoma lolimba + mchira wokulirapo wogawika + mandrel wolimba; kukulitsa chigoba cha mbali zitatu kumapereka kukana kwabwino kwambiri kwa chassis yamagalimoto amalonda
