Kufunika kwa Nthawi Yoyikiratu Pamakina a Resistance Spot Welding

M'dziko la kuwotcherera, kulondola ndikofunikira. Resistance spot kuwotcherera ndi chimodzimodzi. Chinthu chimodzi chofunikira chomwe nthawi zambiri sichidziwika koma chimakhala ndi gawo lofunikira kwambiri pakukwaniritsa ma welds apamwamba kwambiri ndi nthawi yodzaza. M'nkhaniyi, tiona kufunika kwa preloading nthawi mu kukana malo kuwotcherera makina.

 Kumvetsetsa

Resistance spot welding, njira yolumikizira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto, zakuthambo, ndi kupanga, imaphatikizapo kuphatikiza mapepala awiri azitsulo pogwiritsa ntchito kukana kwamagetsi ndi kukakamiza. Kupeza weld yolimba, yolimba kumadalira kuwongolera magawo osiyanasiyana, ndi nthawi yodzaza ndi nthawi yomwe imakhala yofunika kwambiri.

Kodi Nthawi Yotsitsa Ndi Chiyani?

Nthawi yotsegulira isanakwane, pankhani ya kuwotcherera malo okana, imatanthawuza nthawi yomwe ma elekitirodi amapanikizidwa ndi mphamvu musanayambe kuwotcherera. Ndi nthawi yomwe mapepala awiri azitsulo amakumana, ndipo ndondomeko yeniyeni yowotcherera imayamba.

N'chifukwa Chiyani Nthawi Yotsegula Ndi Yofunika?

1. Kulumikizana Kwazinthu: Kuika patsogolo koyenera kumatsimikizira kuti mapepala azitsulo akukhudzana kwambiri. Kulumikizana koyamba kumeneku ndikofunikira chifukwa mipata iliyonse kapena kusalumikizana bwino kungayambitse zowotcherera zofooka kapena kuwonongeka kwa weld. Mphamvu yomwe imagwiritsidwa ntchito ponyamula katundu imathandiza kuthetsa zolakwa zotere.
2. Kutentha Kutentha: Nthawi yotsegulira imathandizanso kuwongolera kutentha koyambirira komwe kumapangidwa pakagwiritsidwa ntchito. Ngati magetsi ayambika musanalowetse bwino, kutentha kwambiri kumatha kusokoneza zogwirira ntchito kapena kupanga matenthedwe osayenera, kusokoneza mtundu wa weld.
3. Kusasinthasintha: Kusasinthasintha ndikofunikira pakuwotcherera malo okana. Pokhala ndi nthawi yodziwikiratu, ogwiritsira ntchito amatha kutengera zomwezo pa weld iliyonse, kuwonetsetsa kuti ndizofanana komanso zodalirika popanga.
4. Electrode Wear: Kulowetsa kosakwanira kumatha kufulumizitsa kuvala kwa electrode. Mphamvu yomwe imagwiritsidwa ntchito potsitsa imathandizira kuti magetsi azikhala bwino pakati pa maelekitirodi ndi zida zogwirira ntchito, kuchepetsa kutha komanso kukulitsa moyo wamagetsi.
5. Chitetezo: Nthawi yokwanira yojambulitsa ndiyofunikira pachitetezo cha opareshoni. Zimachepetsa chiopsezo cha ma elekitirodi kumamatira ku zida zogwirira ntchito, zomwe zingayambitse ngozi poyesa kuzilekanitsa.

Kukonzanitsa Nthawi Yoyikiratu

Kuti mukwaniritse zowotcherera bwino, ndikofunikira kudziwa nthawi yoyenera kuyikanso zida zenizeni ndi momwe kuwotcherera. Zinthu monga mtundu wazinthu, makulidwe, ndi zinthu zomwe zimafunikira weld zonse zimakhudza nthawi yoyenera kutsitsa. Opanga nthawi zambiri amayesa ndi kuyesa kwakukulu kuti akhazikitse njira zabwino kwambiri zogwiritsira ntchito.

Pomaliza, ngakhale kuti nthawi yotsegulira ikhonza kuwoneka ngati nkhani yaying'ono pakuwotcherera malo, ndiye kuti ndi chinthu chofunikira kwambiri chomwe chimatha kupanga kapena kuphwanya mtundu wa weld. Kuwonetsetsa kuti nthawi yoyenera kulongedza sikungobweretsa ma welds amphamvu, odalirika komanso kumapangitsa chitetezo ndi magwiridwe antchito pakuwotcherera. Ndi chikumbutso kuti m'dziko la kuwotcherera mwatsatanetsatane, mphindi iliyonse ndiyofunikira.
