Botolo la Hex la Kapangidwe Kapamwamba Kwambiri
Mabotolo a Mutu wa Hex Wamba
Mabotolo amenewa nthawi zambiri amakhala mabotolo a C-grade coarse, ndipo ochepa ndi mabotolo a A ndi B-grade precision. Ali ndi mphamvu zochepa ndipo nthawi zambiri amagwiritsidwa ntchito ngati zomangira kwakanthawi kapena zolumikizira m'malo ena onyamula katundu.
Magawo Ofunika:
Amatsatira miyezo monga GB/T 5780-2000 (ulusi wosakwanira) ndi GB/T 5781-2000 (ulusi wonse). Mafotokozedwe a ulusi amakhudza M5-M64. Magiredi a magwiridwe antchito makamaka ndi 3.6, 4.6, ndi 4.8. Mwachitsanzo, bolt ya kalasi ya 4.8 ili ndi mphamvu yolimba ya 400MPa ndi mphamvu yolimba ya 320MPa. Zipangizozo makamaka ndi chitsulo cha Q235. Magiredi A ndi B ndi ma bolt olondola, omwe amapereka kulondola kwakukulu komanso amawononga ndalama zambiri. Ma bolt a Giredi C ndi ma bolt okhwima, okhala ndi kulondola kochepa kwa makina koma mitengo yotsika; ndi ma bolt wamba omwe amagwiritsidwa ntchito kwambiri m'mapangidwe achitsulo.
Mapulogalamu:
Yoyenera kukhazikika kwakanthawi kwa nyumba zachitsulo, monga kuyika ndi kulumikiza zida zachitsulo panthawi yomanga; komanso yoyenera nyumba zina zonyamula katundu, monga zothandizira zazing'ono zachitsulo, kulumikiza zida zosanyamula katundu, ndi kulumikizana m'nyumba zachitsulo zomwe zitha kusweka pambuyo pake.
Maboti akuluakulu a mutu wa hexagonal amphamvu kwambiri
Izi ndi zomangira zofunika kwambiri m'zigawo zapakati zonyamula katundu za zitsulo, zomwe nthawi zambiri zimagwiritsidwa ntchito m'magawo olumikizirana (omwe ali ndi boluti imodzi, nati imodzi, ndi ma washer awiri). Kagwiridwe kake ndi kulondola kwake kumaposa kwambiri maboluti wamba.
Magawo apakati:
Zimagwirizana ndi muyezo wa GB/T 1228-2006; magiredi a magwiridwe antchito makamaka ndi 8.8 ndi 10.9. Maboluti a Giredi 10.9 ali ndi mphamvu yokoka ya 1040-1240 N/mm², mphamvu yokoka ya osachepera 940 N/mm², ndi kuuma kwa Vickers pakati pa 312 ndi 367. Maboluti a Giredi 8.8 ali ndi mphamvu yokoka ya 830-1030 N/mm² ndi mphamvu yokoka ya 660 N/mm². Amapangidwa kwambiri ndi chitsulo chapakati cha kaboni kapena chitsulo chosakanikirana ndipo amafunika kutentha kuti awonjezere mawonekedwe awo. Maboluti ena amphamvu kwambiri amathandizidwanso ndi ma galvanizing ndi mankhwala ena oletsa dzimbiri.
Zochitika Zogwira Ntchito:
Zoyenera kugwiritsidwa ntchito m'zigawo zapakati za zitsulo zonyamula katundu, monga kulumikiza chitsulo m'milatho, kulumikizana kwa ma node m'zipinda zazitali zachitsulo, kukhazikika kwa nsanja zotumizira mphamvu, ndi kumangirira zida zonyamula katundu m'zipinda zazikulu zachitsulo za fakitale. Zochitika izi zili ndi zofunikira kwambiri kuti kulumikizana kukhale kolimba komanso kotetezeka. Mabotolo akuluakulu a hexagonal amphamvu kwambiri amatha kulimbitsa mphamvu ya torque molondola, kudalira kukangana kuti kusamutse katundu ndikuwonetsetsa kuti nyumbayo ikugwira ntchito bwino.
Zinthu Zodziwika ndi Malangizo Ogwiritsira Ntchito
Ubwino Wodziwika:
Kapangidwe ka mutu wa hexagonal kumathandiza kugwiritsa ntchito ndi kulimbitsa wrench, zomwe zimapangitsa kuti ikhale yoyenera kuyikidwa ndi makina komanso ndi manja. Ambiri amagwiritsidwa ntchito ndi mtedza wa hexagonal ndi ma washers oyenerera kuti awonjezere kutseka ndi kukhazikika kwa kulumikizana. Ena amalandira ma galvanizing otentha kapena mankhwala ena oletsa dzimbiri kuti awonjezere nthawi yawo yolimbana ndi dzimbiri kuti agwiritsidwe ntchito panja.
Malangizo Ogwiritsira Ntchito:
Maboluti osiyanasiyana sayenera kusakanikirana. Mwachitsanzo, boluti yamphamvu kwambiri ya kalasi 10.9 singagwiritsidwe ntchito ndi nati wamba ya kalasi 4.8. Mphamvu ya maboluti amphamvu kwambiri iyenera kuyendetsedwa mosamala panthawi yoyika; cholakwika cha torque wrench chiyenera kukhala mkati mwa ± 5% kuti tipewe kulimbitsa kwambiri, zomwe zingayambitse kusweka kwa boluti, kapena kulimbitsa pang'ono, zomwe zingakhudze mphamvu yolumikizira. Kusungirako kuyenera kutetezedwa ku mvula ndi chinyezi kuti tipewe dzimbiri ndi kuwonongeka kwa ulusi. Ngati boluti ndi nati sizikugwirizana, kugwiritsa ntchito kwawo ndikoletsedwa kwambiri.
