Mitundu ya rivets, zizindikiro unsembe ntchito

Nthawi zambiri, banja la fasteners rivet ndi chimodzi cha zosankha yodalirika chifukwa chikukonzekera. Kumasiyana kupanga chatsekedwa yolusa mitsempha, chifukwa mu mphamvu ndi durability ya kapangidwe anagwirizana. Chinthu china ndi chakuti pogwiritsa ntchito mfundo za ubwenzi si nthawi zonse mwaukadaulo chovomerezeka. Komabe, pali mitundu yosiyanasiyana ya rivets, amene amasiyana kapangidwe ndi makhalidwe ena zimene zimapangitsa ntchito bwino zosiyanasiyana.

Main makhalidwe a fasteners

Pankhani kusankha kwa fastener khalidwe ndicho kusamvana. N'komwe magawo angapo, Pakati - m'mimba mwake wa ndodo. Izo zikhoza kukhala kwa mamilimita 1 36 pa kutalika mamilimita 2 mpaka 180. Sitiyenela kuganiza kuti makulidwe wamkulu mwachindunji ndi mphamvu ya rivet lapansi. Zitsulo ndodo mapanelo 10 mm mu makulidwe akhoza kukhala amphamvu kwambiri tubular mkuwa zinthu, ndi m'mimba mwake wamkulu kuposa 20 mm. Komabe, zimadalira chikhalidwe cha katundu amene anawamasulira - zina zaphindu ntchito woonda-mipanda mbali tubular.

rivets chitsanzo ndi mutu otsika wozungulira basi osiyanasiyana ka akalozera makulidwe - kuchokera 1 mpaka 10 mm, kutalika Pankhaniyi zimasiyanasiyana 4 80 mm. Zamgululi ndi chipewa mosabisa ndi makulidwe mu zosiyanasiyana 2-36 mamilimita ndi kutalika 4-180 mm. Ambiri yaitali mbali mitundu countersunk wa rivets, amene angagwiritsidwe ntchito niches akuya mamilimita 200.

Gawo mwa dongosolo

Pali Mabaibulo ambiri komanso miyambo ina yofanana fastener lapansi. muyezo A n'chofunika spacer ponena molumikizana bulky, zofewa ndi zipangizo Chimaona. Lumikizanani ndi mutu wa rivet pa unsembe zikuoneka kuti amalola kugawira katundu dera lalikulu pa mbali kumbuyo. Ntchito ndi matabwa ntchito khumudwitsidwa chitsanzo. Pamene khazikitsa ndodo ndi kukodzedwa ndi ndipamene khumudwitsidwa makutu, zimene pamapeto, kupereka amasiya n'zosiyana ndi kukonza zinthu. Childs, zotayidwa izi rivets kuti akhoza kuthana ndi mapanelo kuwala. Chidwi ndi mnogozazhimnye nkhani anafuna kujowina zipangizo za makulidwe osiyana. Anapanga wagawo mu nkhani iyi ndi chilengedwe, kotero amagwiritsidwa ntchito kawirikawiri pamene palibe Kumvetsa kukula kwa workpieces. Komabe, mungachite kwambiri zamakono kupereka kutukula zitsanzo limodzi. Ndi dongosolo lino, potseka kamera zinthu zikhoza kupezeka mu milingo makumi. Pankhaniyi, chotengera maziko, ndodo imodzi yokha adzachichita.

Gulu la nkhani

Ambiri rivets amapangidwa ndi zitsulo. Makamaka ntchito zotayidwa, zitsulo, mkuwa ndi mkuwa. Pafupifupi onse zitsanzo za mtundu wa zofuna mkulu mu mawu a chitetezo dzimbiri. Zotayidwa ndi mkuwa rivets amagwiritsidwa yodziwika ndi ductility ndi otsika kulemera. fasteners zitsulo ndi zambiri ntchito zojambula komwe muyenera kuonetsetsa mphamvu zokwanira.

Common ndi ntchito rivets pulasitiki. Ambiri, iwo anapanga polyamide, amenenso angathe kupereka kugwirizana kwambiri. Kumene, mu index mphamvu ya njirayi ikaseweredwa zitsulo. Komabe, ngati rivet galvanic dzimbiri kwa nthawi yaitali angathe sitingakumane ndi zonse mkulu chitetezo chinyezi, pulasitiki si poyamba m'gulu anachita pa oipa ngati amenewo kukhudzana. Komanso, polyamide Kodi makhalidwe magetsi ndi optimally interacts ndi zipangizo lopangidwa ndi nsanganizo ndi fiberglass. Lero, luso otentha adhesions kukhala njira ndi mulibe rivets pulasitiki zipangizo gulu, zomwe analenga dongosolo monolithic.

M'zigawo ndi yamazinga rivets

Kukhalapo kwa ulusi ofanana rivets mankhwala ena zitsulo, koma mu nkhani iyi akuyendera iwiri amaganiza fixation njira. Kuti, chinthu thupi anadzetsa dzenje okonzeka, kenako mbali zina za wachiwiri malaya gawo linayikidwa ndi screwing. Njira zimenezi zili ndi ubwino wake mu mawonekedwe a kudalirika ndi chomasuka kukhazikitsa, koma osati nthawi zonse n'zotheka kuzitsatira. Choncho, m'pamenenso ntchito utsi chitsanzo. Ngati rivets yamazinga wofunikila okhwima fixation kupotoza membala wothandiza, utsi kapangidwe mfundo zikutanthauza mapindikidwe kumapeto kulenga amasiya. Tinganene mfundo expansible, ndi thickening ya kapangidwe tubular, komanso ena njira nsonga rivet mapindikidwe ncholinga chikukonzekera.

zida unsembe

opaleshoni imagwiridwa mu magawo angapo. Woyamba kubowola dzenje analengedwa, imene mayikidwe gawo idzachitike. Pafupifupi mitundu yonse ya rivets kuti kuikidwa recess ndi awiri amene ali 10-15% kuposa kakakulu ndodo ntchito. limapezekapezeka kachulukidwe Pankhaniyi ogwirizana. Mu fasteners okonzeka dzenje Integrated kuti kapu ili pa mbali n'zosiyana padziko ntchito.

Pa nthawi imeneyi, njira atakhala zingasiyane. Yamazinga chitsanzo n'zotheka kukonza lake, popanda kugwiritsa ntchito zipangizo zapadera. Komabe mtundu zachiwawa rivets zitsulo spacers hardware kapena olumala okha pogwiritsa ntchito zipangizo zapadera. Rasklepka omenya kapena opangidwa magetsi nyundo pistons, izo zimatengera mtundu wa fastener.

Kodi applicable rivet?

Makamaka fasteners ntchito yomanga makampani ndi anakonza mpandawo. Yomanga yaikulu njira imeneyi si kugwirizana, koma kutsirizitsa kukongoletsa zipangizo mu mawonekedwe a mapanelo, mapepala ndi mbale zambiri ali wokwera mu njira iyi. Technology ndi kukonza molondola kulola ntchito hardware amenewa ndi kupanga. Mwachitsanzo, zotayidwa rivet adzatsekeredwa kugwirizana chipboard gululi. zinthu zitsulo ntchito mofanana mizere makina zomanga msonkhano pa unsembe wa pepala zitsulo ndi mbali.

Pomaliza

awiri achepetsa njira zambiri ubwino pa fasteners ena. Koma iye ali, ndi zolakwika zake. chakuti ambiri kudzadzipeza wa mtundu uwu lakonzedwa disassembly. Mwachitsanzo, mitundu zachiwawa wa rivets angatchedwe imodzi kuchoka - mu zimadziwa kuti zitha kuikidwa pamalo amodzi popanda kuthekera kwa kukonzanso unsembe. Zimenezi Nkofunika kwambiri zachuma monga luso - monga nuance zida metiz chandamale mfundo okhazikika. Chotsani rivet akhoza chokhudzana yekha ndi mapindikidwe wa mankhwala, koma ngakhale mu nkhani iyi, chipangizo ndi zina rivet kugwirizana kudzipatula METIZ zosatheka.
