Mkulu mphamvu wakuda mtedza durability? 

Wina akafunsa za 'kulimba kwa mtedza wakuda,' lingaliro laposachedwa limakhala la zokutira - kuti black oxide kapena black phosphate kumaliza. Koma muzochita, ndiye gawo lowoneka chabe. Kukambirana kwenikweni kumayambira ndi zinthu zoyambira, njira yochizira kutentha, ndipo kunena zoona, malo enieni omwe amayenera kukhalapo. Ndawona zolemba zambiri zomwe zimangoyitanitsa 'Giredi 8 yakuda' osaganizira ngati ndi malo owuma, amkati kapena nyumba yakunja yomwe ikuyang'anizana ndi kupopera mchere wamchere. Gawo la 'wakuda' sichiri chishango chamatsenga; ndizothandizira kukana dzimbiri ndi kukongola, koma 'mphamvu yapamwamba' ndi 'kukhazikika' ndi nkhani yozama kwambiri yaumisiri.

Kulemba 'Mphamvu Yapamwamba' - Sichilemba Chake

Pamzere wathu, 'mphamvu zazikulu' nthawi zambiri zimaloza ku makalasi a katundu monga 8, 10, kapena 12. Kwa mtedza, kufananitsa mphamvu ya bawuti ndikofunikira kuti tipewe kuvula ulusi-malo olephera akale. Tikukamba za zitsulo zozimitsidwa ndi zotentha zapakati pa carbon, kapena zitsulo za alloy zamagulu apamwamba. Kukhazikika pansi pa katundu kumadalira izi. Ndikukumbukira pulojekiti ya makina olemera omwe kasitomala anaumirira kugwiritsa ntchito mtedza wa Giredi 5 womalizidwa wakuda ndi mabawuti a Sitandade 8, poganiza kuti mtunduwo umagwirizana ndi kukongola. M'miyezi yochepa chabe, tinali ndi malipoti oti sitinagwirizane. Mtedzawo unabala. 'Wakuda' anali wabwino; mphamvu zakuthupi zinali zosagwirizana. Ndiko kulephera kolimba kokhazikika pamatchulidwe, osati kumatira.

Malo opangira zinthu ku Yongnian, Hebei, ndipamene mumawona izi zikugwira ntchito. Wopereka ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., ikugwira ntchito kuchokera ku maziko akuluakulu opangirawo, ili ndi zipangizo zoyendetsera zitsulo ndi kutentha kwamphamvu. Malo awo pafupi ndi njira zazikulu zoyendera simalo ogulitsa okha; zimatanthawuza kuperekedwa kosasinthika kwazinthu zopangira ndi zopangira matani olemetsa omwe kupanga kwamphamvu kwamphamvu kumaphatikizapo. Pamene mukuchita ndi madongosolo apamwamba kwambiri, okwera pamafakitale, kukhazikika kwazinthuzo kumakhudza kusasinthika kwamtundu - chofunikira, chomwe nthawi zambiri chimanyalanyazidwa, chinthu chokhazikika.

Ndiye mukuweruza bwanji? Zitsimikizo ndi malipoti oyesa. Wopanga wodalirika ayenera kupereka ma cert azinthu ndi umboni wamakina. Kulimba, kulimba kwamphamvu, katundu wotsimikizika - manambalawa amafotokoza nkhani yokhazikika kale mtedza usanawone chikwanje. Kutsirizitsa kwakuda kuli pafupifupi kuganiza mozama mu labotale yoyesera, koma ndi chinthu choyamba chomwe munthu wogula amawona.

The Black Finish - Ntchito Yoposa Mtundu

Tiyeni tikambirane za 'wakuda' wokha. Nthawi zambiri zimakhala zokutira zotembenuza, osati zokutira. Sichimawonjezera makulidwe ngati plating ya zinc, yomwe ndi yofunika kwambiri kuti musunge kulekerera kwa ulusi pa mtedza wamphamvu kwambiri. Ntchito yake yayikulu ndikukana dzimbiri, koma ndi yofatsa. Amapereka chotchinga choyenera kukana okosijeni mumlengalenga wabwinobwino ndipo amapereka maziko abwino osungira mafuta kapena sera. Nthawi zambiri timaviika mtedza wakuda mumafuta opepuka, omwe amalimbitsa chitetezo chawo kwakanthawi kochepa ndikupangitsa mawonekedwewo kuwala pang'ono.

Komabe, ndakhala ndi kusagwirizana kwanga ndi makasitomala omwe akuyembekezera kuti mapetowa azichita ngati galvanizing yotentha. Sizingatero. Pamalo okhala ndi chinyezi chambiri kapena mankhwala, black oxide yokha imawonetsa dzimbiri lofiira mwachangu. Kukhalitsa kwake m'malo owononga ndizochepa. Tinaphunzira izi movutikira pa gulu lotumizidwa ku nyumba yosungiramo katundu pafupi ndi gombe. Mtedzawo unkawoneka wabwino pobereka koma unkawoneka wamakamaka pakatha milungu ingapo. Kukonzekera sikunali 'kwabwino' kumaliza kwakuda; zinali kusunthira kuzinthu zina zonse za chilengedwe chimenecho.

Ubwino wa mapeto akuda kuti ukhale wolimba ndi wosadziwika. Ili ndi kukana bwino kwa abrasion poyerekeza ndi zokutira zina zomatira. Chophimbacho chimaphatikizidwa pamwamba, kotero sichimatuluka mosavuta panthawi ya kuika kapena kugwedezeka. Izi zimathandiza kusunga zotchinga dzimbiri zomwe zimapereka. Kwa mapulogalamu omwe msonkhano ukhoza kuwona kugwiridwa kwakukulu kapena kukwapula kakang'ono, ndilo phindu lowoneka.

Kukhalitsa Padziko Lonse - Kugwedezeka, Kutentha, ndi Kutopa

Kukhalitsa sikungokhudza dzimbiri. Kwa mtedza wamphamvu kwambiri, kuthekera kwake kukhalabe pansi pa katundu wosunthika ndikofunikira. Apa ndipamene mawonekedwe amapangidwe ngati torque yomwe ilipo (monga ma locknuts a nayiloni) kapena ulusi wopunduka umabwera, womwe nthawi zambiri umagwiritsidwa ntchito pambuyo pa njira yakuda ya oxidizing. Kugwirizana pakati pa chinthu chotseka ndi mapeto akuda kuyenera kuganiziridwa. Nthawi zina, makulidwe okutira, ngakhale ochepa, amatha kukhudza kukhazikika kwa torque. Ndi ndondomeko yaying'ono yoyendetsera ndondomeko yomwe imalekanitsa gulu labwino kuchokera ku lalikulu.

Kutentha ndi wina wakupha mwakachetechete. Mtedza wozimitsidwa komanso wotenthedwa mwamphamvu amakhala ndi malire a kutentha kwapamwamba. Kupitilira apo, ndipo mkwiyo umakokedwa, mphamvu imatsika, ndipo kulimba kumatsika. Ndikukumbukira kufunsa kwa gawo la injini komwe kutentha kwa ntchito kunali pafupi ndi malire a kalasi yazinthu. Tinayenera kukankhira kumbuyo ndikupangira giredi ina, ngakhale kuti kasitomala amayang'ana kwambiri mtengo wake. Muyezo wa ‘nati wakuda wamphamvu kwambiri’ sunali yankho lolondola. Kumaliza kwakuda komweko kumathanso kutayika pakatentha kwambiri, komwe kumakhala kodzikongoletsera koma nthawi zina ndikofunikira.

Kutopa ndikosavuta kwambiri. Zimachitika pamagulu opsinjika bwino pansi pa mphamvu zolimba. Ubwino wa ulusi wogubuduza, kusakhalapo kwa zolakwika zapamtunda kapena ming'alu yaying'ono kuchokera kukupanga, komanso kusalala kwa kumaliza kumakhudza moyo wa kutopa. Njira yapamwamba yakuda yakuda, yomwe imakhala dzimbiri loyendetsedwa bwino, siyenera kuyambitsa hydrogen embrittlement-chiwopsezo ndi njira zina za electroplating. Izi zimapangitsa mtedza wakuda wa okusayidi wokonzedwa bwino kukhala chisankho chotetezeka pakugwiritsa ntchito mwamphamvu kwambiri, kutopa kwambiri kuyambira poyambira.

Kufotokozera za Moyo Weniweni Wautumiki

Ndiye, mumafotokozera bwanji kulimba? Umayamba ndi chilengedwe. M'nyumba, molamulidwa? Oxidi wakuda wakuda pa mtedza wa Class 10 ndiwokwanira. Panja, mafakitale, kapena chinyezi chambiri? Mungafunike okusayidi wakuda ngati maziko koma tchulani chikhomo chowonjezera cha sera kapena kuviika kwamafuta olemera. Kwa madera ovuta, kutsirizira kwakuda kungakhale kokongoletsera pansi pa makina okhwima kwambiri, ngakhale kuti ndizochepa kwambiri kwa mtedza chifukwa cha kulekerera kwa ulusi.

Zimakhudzanso mgwirizano ndi wopanga. Mufunika wogulitsa yemwe amamvetsetsa izi, osati yemwe amagulitsa mankhwala amtundu uliwonse. Mukawunika kuthekera kwa kampani, monga zomwe mungawone patsamba monga https://www.zitaifasteners.com, Ndimayang'ana umboni wa kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake-momwe amasamalira maere a kutentha kwa kutentha, khalidwe lawo loyang'ana pazitsulo zomatira ndi zowonongeka (maola oyesera mchere), komanso kufunitsitsa kwawo kupereka deta yaukadaulo. Wopanga wophatikizidwa m'malo opangira zinthu ngati Yongnian nthawi zambiri amakhala ndi mwayi wapadera, wamagulu operekera zida zomaliza ndi zofunikira zosiyanasiyana.

Pomaliza, musachepetse unsembe. Durability idapangidwa mkati koma imatha kukhazikitsidwa. Kuthamangitsa mtedza wakuda wamphamvu kwambiri ukhoza kuutambasula, kusokoneza mphamvu yake yotchinga ndi zotchinga za dzimbiri. Kugwiritsa ntchito mafuta olakwika pa ulusi kumatha kulumikizana ndi zokutira zakuda za oxide. Wopangayo ayenera kudziwa zomwe akuchita. Tayambanso kuphatikiza zolemba zoyambira ndi zotumiza zambiri chifukwa zimapulumutsa mutu kumunsi.

Pansi Pansi - Dongosolo Loyenera

Pamapeto pake, kukhazikika kwa mtedza wakuda wamphamvu kwambiri ndi katundu wadongosolo. Ndilo ukwati wa zinthu zolondola zapakatikati ndi zida zamakina ('mphamvu yayikulu'), chithandizo choyenera komanso chogwiritsidwa ntchito bwino chapamwamba ('chakuda'), ndi kusankha koyenera kwa malo ogwirira ntchito. Simungathe kusudzulana wina ndi mzake. Kumaliza kwakuda kwakuda pa mtedza wosalimba kumalephera. Mtedza wa Grade 12 wotenthedwa bwino wokhala ndi zokutira zakuda zowoneka bwino, zowoneka bwino zimayamba kuwononga, ndipo dzenje la dzimbiri limakhala lovutikira, zomwe zimapangitsa kuti pakhale kutopa.

Langizo langa ndikuyesa kuyesa kwenikweni ngati kuli kotheka. Onjezani gulu lachitsanzo, ikani mumayendedwe oyeserera, kapena kungoyesa kuyesa kwa dzimbiri komwe kumayendetsedwa. Onani momwe mapeto akuyendera, yang'anani ngati pali vuto pakuyika, ndikutsimikiziranso mgwirizano wa torque-tension. Mayeso othandizawa amakuuzani zambiri kuposa pepala lililonse.

Pamapeto pake, ndi chigawo chomwe chikuwoneka chophweka koma chimakhala ndi mphamvu zovuta. Kupeza kulimba kwake ndikokhudza kulemekeza zovutazo, kuyang'ana kupitirira mtundu wa pamwamba, ndikuyang'ana pa mndandanda wonse wazinthu, kupanga, mawonekedwe, ndi ntchito. Ndiko kumene ntchito zenizeni, zodalirika zimamangidwa.
