Kodi kuwotcherera matako ndi chiyani?

Kuwotcherera matakoamagwiritsidwa ntchito mochulukira pokonza zitsulo zamakono, kudzera muukadaulo wowotcherera matako, zitsulo zomwezo kapena chitsulo chosiyana monga mkuwa ndi aluminiyamu zitha kukhala zolimba. Ndi chitukuko cha mafakitale, ukadaulo wowotcherera butt umagwiritsidwa ntchito kwambiri pamagetsi ndi magetsi, magalimoto amagetsi atsopano ndi mafakitale ena. Nkhani yotsatirayi iyankha chidziwitso cha kuwotcherera matako mwatsatanetsatane.

Kukaniza kuwotcherera butt

Kukaniza kuwotcherera matako ndi mtundu wa kuwotcherera gawo olimba mu kutentha kwambiri pulasitiki boma, ndi kugwirizana olowa akhoza recrystallization ndi kufalikira onse kwenikweni, koma onse ndi olimba gawo kugwirizana.

Ubwino waButtWelding

a) Kukaniza matako kuwotcherera zida ndi zosavuta, zochepa kuwotcherera magawo, zosavuta mbuye, zosavuta kukwaniritsa kudzilamulira;

b) Kuchepetsa pang'ono kwa mbali zowotcherera za kukana, kupulumutsa zida, ma burrs ochepa, zomwe zimathandiza kuti njira yomaliza ikhale yosavuta;

c) kuwotcherera kwa matako kung'anima kumatenthetsa kwambiri, kumatha kuwotcherera mbali zazikulu, ndipo kwagwiritsidwa ntchito powotcherera mapaipi agasi okhala ndi gawo la 100000mm2;

d) kung'anima butt kuwotcherera chifukwa lintel alipo kwa nthawi yochepa, milliseconds ochepa chabe, malo ake kusintha chisawawa, ndi nthawi okwana Kutentha lonse mapeto a nkhope kuwotcherera ndi yunifolomu, kotero mosalekeza kuwotcherera kung'anima sikungathe kuwotcherera a gawo yaying'ono, komanso welds welds ndi zigawo zokulitsidwa (monga mapepala woonda, etc.);

e) Kumapeto kwa kung'anima, chitsulo chochepa kwambiri cha zitsulo zamadzimadzi chidzapangidwa pamwamba pa weldment, kotero kuti zonyansa za oxide pamtunda zimakhala zosavuta kutulutsa ndi zitsulo zamadzimadzi pamtunda wapamwamba wa mawonekedwe, kotero kuti cholumikizira chowotcherera cha flash butt ndi chapamwamba kwambiri, ndipo mitundu yowotcherera imatha kukhala yochulukirapo, ndipo zida zosiyanasiyana zimatha kuwotcherera.

f) Palibe zodzaza zomwe zimafunikira pakuwotcherera, ndipo kugwiritsa ntchito zinthu ndizokwera;

Pamene magawo oyenerera a mawotchi a matako amasankhidwa, zolumikizira zapamwamba zomwe zili ndi zinthu zofanana ndi zida zoyambira zimatha kupezeka.

a) Zigawo zazikuluzikulu zowotcherera ku resistance butt ndi:

Tambasula kutalika, kuwotcherera panopa kachulukidwe (kapenakuwotcherera panopa), nthawi yowotcherera, kuthamanga kuwotcherera ndi kuthamanga kwapamwamba kwapamwamba.

b) Zigawo zazikulu za kuwotcherera kwa flash butt ndi:

Kung'anima siteji: kusintha kutalika kwa kutambasula, kusunga kung'anima, kuthamanga kwa flash, kachulukidwe kakali pano;

Gawo lapamwamba lopangira: ndalama zopangira zida zapamwamba, kuthamanga kwambiri, kuthamanga kwapamwamba, kukakamiza;

Preheating siteji: preheating kutentha, preheating nthawi.

Ntchito ya kutambasula kutalika ndi kuonetsetsa choloŵa chofunika (kuwotcherera mbali kufupikitsa) ndi kusintha kumunda kutentha pamene Kutentha tanthauzo ndi ntchito akhoza kusankhidwa molingana ndi kuwotcherera gawo gawo ndi katundu katundu, mchitidwe amasonyeza kuti kutambasula kutalika sikuyenera kukhala zochepa. kuposa theka la m'mimba mwake wa gawo lowotcherera, ndiye kuti, l = 0.6 ~ 1.0d (d ndi m'mimba mwake wa matabwa kapena kutalika kwa mbali ya bwalo) ndiloyenera. Pa nthawi yomweyi, pamene kuwotcherera zipangizo zosiyana, kuti apeze kutentha kwapakati (nthawi zina poganizira za kuuma kwazitsulo zopanda chitsulo), ma welds awiriwa ayenera kugwiritsa ntchito utali wotambasula wosiyana.

Kuwotcherera pakali pano nthawi zambiri kumasonyezedwa ndi kachulukidwe kameneka, ndipo kachulukidwe kameneka ndi nthawi yowotcherera ndi magawo awiri akuluakulu omwe amatsimikizira kutentha kwa kutentha, ndipo akhoza kusinthidwa moyenera kwa wina ndi mzake. Pochita, tikulimbikitsidwa kusunga ubale wina pakati pa kachulukidwe kakang'ono kameneka ndi nthawi yochepa yowotcherera, ndikugwiritsa ntchito ndondomeko yovuta pamene gawo la mtanda likuchepa. Kachulukidwe kakachulukidwe kakachulukidwe ka kung'anima kopitilira muyeso, zida zachitsulo zokhala ndi magetsi abwino komanso matenthedwe, ndi zida zowotcherera zokhala ndi gawo lokulitsidwa ziyenera kukhala zapamwamba. Pakuwotcherera kung'anima kwa matako ndi ma welds agawo akulu, kachulukidwe kameneka kuyenera kukhala kochepa.

Onse kuthamanga kuwotcherera ndi pamwamba forging kuthamanga ali ndi mphamvu pa kutentha kutentha kwa kukhudzana pamwamba ndi mapindikidwe pulasitiki wa madera osiyana ndi moyandikana. Kuthamanga kwapamwamba kwambiri komanso kuthamanga kwamphamvu kwamphamvu kumatha kufananizidwa, ndipo kuthamanga kwapamwamba kungathe kuchepetsedwa moyenera pamene liwiro lapamwamba lopanga lili lalikulu mokwanira.

TheDchitukukoPmwayi waButtWelding

Ndi kafukufuku wakuya wa ubale pakati pa kukana kuwotcherera khalidwe ndi kuwotcherera ndondomeko magawo ndi ukadaulo wodziwira pa intaneti, kukhazikika kowotcherera kumatha kupezeka. Komanso, zipangizo kuwotcherera akhala zina kukodzedwa, ndi ntchito osiyanasiyana kuwotcherera kukana ndi zambiri lonse. Ndi kupita patsogolo kosalekeza kwakukana kuwotcherera luso, kukana kuwotcherera kudzakhala ndi malo ofunikira kwambiri pakupanga mafakitale amtsogolo. Makamaka m'munda wowotcherera wa magawo akulu akulu ndi zitsulo zofananira, kuwotcherera kwa matako kung'anima kuli ndi chiyembekezo chabwino cha chitukuko.

Chidule

Ndi chitukuko cha makampani mphamvu zatsopano, ntchito kuwotcherera mkuwa ndi zotayidwa kugwirizana, kukana kuwotcherera luso basi zikugwirizana ndi zosowa za msika, pamodzi ndi kukana kwatsopano kuwotcherera ndondomeko ndi adaptive kulamulira luso, kukana kuwotcherera m`tsogolo chitukuko adzakhala kubweretsa chisangalalo chachikulu.
