Cold extrusion ndi njira yofunikira kwambiri popanga zomangira, zomwe zimapereka zabwino zambiri monga kulimbikitsa mphamvu zakuthupi komanso kutsika mtengo. Mu blog iyi, tikambirana mwatsatanetsatane za makhalidwe ozizira extrusion ndondomeko ndi kupereka malangizo ofunikira processing fastener.

Pankhani yamakampani ndi kupanga, ma bolts ndi zolumikizira zofunika kwambiri. Makamaka m'malo olumikizirana bwino komanso ophatikizika, ma bolts owonda a hexagon amakondedwa chifukwa chaubwino wawo wapadera. Pakati pawo, DIN6912 ndi DIN7984 ndi ma bawuti awiri owonda a hexagon socket. Ngakhale ali ndi ntchito zofanana, ali ndi kusiyana kwakukulu pakupanga ndi kugwiritsa ntchito.

Ochapira amatha kuwoneka ngati zing'onozing'ono, zosafunika kwenikweni pamakina akuluakulu, koma ntchito yawo yonyamula katundu ndiyofunikira kuti zitsimikizire kukhazikika ndi kukhulupirika kwazinthu zosiyanasiyana ndi zida. Mu blog iyi, tifufuza mozama za ntchito yonyamula katundu ya ma washer ndi kufunikira kwawo pamagwiritsidwe osiyanasiyana.

Zikafika pakumangirira, kukhathamiritsa kuchuluka kwa katundu ndikofunikira pakuwonetsetsa kukhulupirika kwadongosolo komanso chitetezo chazinthu zosiyanasiyana. Kaya ndikumanga, kupanga, kapena uinjiniya, kumvetsetsa momwe mungakulitsire kuchuluka kwa katundu pogwiritsa ntchito njira zomangira zogwira ntchito ndikofunikira. Mu bukhuli, tiwona njira zazikuluzikulu ndi njira zabwino zokwaniritsira kuchuluka kwa zomangira, kupereka zidziwitso zofunikira kwa akatswiri pamakampani.

Nthawi zambiri, mphamvu ya kugwirizana kwa bawuti kumatsimikiziridwa ndi mphamvu ya bawuti. Kulimba kwa kulumikizidwa kwamphamvu kumakhudzidwa ndi zinthu zingapo, kuphatikiza zinthu zakuthupi za ma bolts ndi zida zolumikizidwa, zomwe zimayikidwa pamaboliti, kutalika kwa ulusi, komanso kukhalapo kwa mphamvu zilizonse zakunja kapena chilengedwe. Ndiye njira zotani zowonjezerera kulimba kwa mabawuti?

Ulusi wakunja mu zomangira ndi mabawuti umagwira ntchito yofunika kwambiri pakuwonetsetsa kukhulupirika ndi magwiridwe antchito a makina amakina. Kuyang'ana koyenera kwa ulusiwu ndikofunikira kuti zitsimikizire chitetezo ndi kudalirika kwa chinthu chomaliza. Mu bukhuli latsatanetsatane, tiwona njira ndi njira zosiyanasiyana zowonera ulusi wakunja mu zomangira ndi ma bolt, kupereka zidziwitso zofunikira kwa akatswiri pantchito zopanga ndi uinjiniya.

Kodi mukuyang'ana kugula mapini a kasupe? Zikhomo za Spring ndi zomangira zomwe zimapereka mgwirizano wotetezeka komanso wodalirika, zosavuta kuziyika, ndizoyenera kugwiritsa ntchito zosiyanasiyana, zimakhala zotsika mtengo, ndipo zimatha kugwirizanitsa mosavuta ndikuyika mkati mwa misonkhano yamakina. Zinthu izi zimaphatikizana kupanga mapini a kasupe kukhala chisankho chodziwika bwino komanso chothandiza poteteza zida zamafakitale ndi makina. Pali zinthu zingapo zomwe muyenera kuziganizira posankha zikhomo za kasupe.

Anthu ambiri amasankha misomali ya koyilo yopangira ntchito zosiyanasiyana zomanga ndi zaukalipentala chifukwa chakuchita bwino kwake komanso kusavuta. Misomali ya coil idapangidwa kuti igwiritsidwe ntchito ndi mfuti za pneumatic misomali, zomwe zimalola kukhomerera mwachangu komanso mosalekeza popanda kufunikira kokwezanso pafupipafupi. Izi zimawapangitsa kukhala otchuka kwambiri m'ntchito zazikulu zomanga, monga kupanga mafelemu, kuwotcha, ndi kuwotcha, komwe kuli kofunikira kwambiri komanso kuchita bwino. Kuonjezera apo, mawonekedwe a misomali a misomali amalola kuti misomali yambiri ikhale yochuluka mu khola limodzi, kuchepetsa nthawi yobwezeretsanso ndikuchepetsa nthawi yopuma. Mphamvu zazikulu zogwirira ntchito komanso kudalirika kwa misomali ya koyilo kumathandizanso kuti azigwiritsa ntchito kwambiri ntchito yomanga.

Zomangira zonse za dowel ndi ma hanger bolt ndi zomangira zosunthika zomwe zimagwiritsidwa ntchito popanga matabwa ndi zomangamanga. Amagawana kufanana kwa kukhala ndi ulusi wa matabwa kumbali imodzi, kuwalola kugwiritsidwa ntchito ndi matabwa kapena zipangizo zamatabwa. Komabe, kusiyana kwakukulu kuli mu ulusi womwe uli kumbali ina. Zomangira za dowel zimakhala ndi ulusi wa matabwa kumbali zonse ziwiri, zomwe zimawathandiza kulumikiza matabwa awiri molunjika. Mosiyana ndi izi, mabawuti a hanger amakhala ndi ulusi wamakina kumapeto kwina, kuwapangitsa kukhala oyenera kulumikiza matabwa ndi chitsulo kapena zinthu zina pogwiritsa ntchito nati kapena bowo. Ma fasteners onsewa amapereka maulumikizidwe amphamvu komanso otetezeka, koma kusiyana kwawo kumawapangitsa kukhala oyenera kugwiritsa ntchito zina.

Maonekedwe a hexagonal amakondedwa kuposa mawonekedwe a square kwa mtedza chifukwa cha zabwino zingapo zothandiza. Choyamba, mawonekedwe a mbali zisanu ndi chimodzi a mtedza wa hexagonal amalola kuti azitha kupeza mosavuta ndi wrench kapena socket kuchokera kumakona angapo, zomwe zimapangitsa kuti zikhale zosavuta kumangitsa kapena kumasula poyerekeza ndi mtedza wa square. Kuphatikiza apo, mbali zisanu ndi imodzi zosalala za nati wa hexagonal zimapereka kugawa kwa makokedwe kwabwinoko, kuchepetsa chiopsezo chozungulira ngodya ndikulola kugwiritsa ntchito mphamvu moyenera pakulimbitsa. Kuphatikiza apo, mtedza wa hexagonal umakhala wowongoka bwino kuposa wa square nut, chifukwa ukhoza kulongedzedwa pamodzi m'magulu ang'onoang'ono, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pomwe malo ali ochepa.
