M'mafakitale opangira, themakina kuwotcherera malo(makamaka apakati-ma frequency inverter) amagwiritsidwa ntchito kwambiri chifukwa chochita bwino komanso kukhazikika kwake. Komabe, ogwiritsa ntchito ambiri amadabwabe: ndi magawo ati omwe amatsimikizira momwe kuwotcherera kumagwirira ntchito? Nkhaniyi ikufotokoza zinthu zitatu zofunika zowotcherera pamakina owotcherera mawanga ndikupereka malangizo othandiza pakuwongolera bwino.
Kuwotcherera Panopa: Pakatikati pa Kulowetsa Mphamvu
Welding current ndiye gwero loyamba la kutentha pamakina owotcherera. Masinthidwe apakati-amasintha magetsi anthawi zonse kukhala apamwamba-ma frequency DC current (kupitirira 1000 Hz), akupereka mphamvu zopitira patsogolo mpaka 30% ya kutentha kwambiri. Izi zimawapangitsa kukhala abwino kwa zida zokhala ndi matenthedwe apamwamba, monga ma aluminiyamu aloyi.
Malangizo Ofunikira:
Fananizani zapano ndi mtundu wa zinthu: Wonjezerani mphamvu ya chitsulo chosapanga dzimbiri, chepetsani ma sheet owonda kuti musapse-kudutsa.
Gwiritsani ntchito chiwongolero chaposachedwa: Kupitilira kapena kuchulukitsidwa kwaposachedwa kumachepetsa spatter pamapulogalamu monga kuwotcherera.
Nthawi Yowotcherera: Kulinganiza Kutentha kwa Kutentha
Kuwotcherera nthawi kumakhudza mwachindunji kugawa kwa kutentha. Chifukwa chakuyankha mwachangu (mu ma milliseconds), mafupipafupi-mafupipafupimakina owotcherera maloamatha kufupikitsa ma weld ndi 30-50% poyerekeza ndi zowotcherera wamba za AC. Mwachitsanzo, kusonkhanitsa magalimoto nthawi zambiri kumangofunika masekondi 1-2 pa malo.
Malangizo Ofunikira:
Gwirizanitsani nthawi ndi yamakono: Kutsika kwa madzi kungafunike nthawi yotalikirapo, koma nthawi yochuluka imafalitsa kutentha ndikuyambitsa kusintha.
Kuzungulira kwakanthawi kwa zida zoyendetsera: Kwa aluminiyamu, sungani nthawi yowotcherera pansi pa masekondi awiri kuti muchepetse kutayika kwa kutentha.
Kupanikizika kwa Electrode: Kuwonetsetsa Kulumikizana ndi Kupanga
Kuthamanga kwa Electrode kumatsimikizira kukhudzana kosasinthasintha ndikuthandizira kupanga nugget yowotchera panthawi yozizira. Makina owotcherera omwe amawotchera mawanga amagwira ntchito mkati mwa 0.2-0.6 MPa, osinthika kudzera pamakina a pneumatic kapena servo.
Malangizo Ofunikira:
Sinthani kukakamiza kwa makulidwe a pepala: Gwiritsani ntchito 0.2-0.3 MPa pamapepala owonda kuti mupewe kulowera; 0.4-0.6 MPa pazinthu zokhuthala.
Ikani pre{{0}pressure and post-forge: Pre-finyani imachepetsa kukhudzana, pomwe kuthamanga kumalimbitsa nugget ndikuchotsa zotuluka.
Synergizing the Three Parameters
Kuwotcherera koyenera kumafuna kugwirizanitsa zoikamo zonse zitatu:
Panopa & Nthawi:Kuchuluka kwamakono kumafuna nthawi yayifupi kuti zisawonongeke; kutsika kwamphamvu kumafuna nthawi yayitali koma kumabweretsa kusokonezeka.
Pressure & Current:Kupanikizika kwambiri kumachepetsa kachulukidwe kakali pano, kumayambitsa ma welds ofooka; kuthamanga kosakwanira kungayambitse kusakanizika bwino.
Malangizo Othandiza:
Yesani ndi Kusintha: Yambani ndi zoikamo zoyambira kutengera mtundu wazinthu ndi makulidwe. Yang'anani ma welds oyesera kuti apeze spatter kapena indentation, ndiye yesani.
Gwiritsani Ntchito Digital Controls: Makina amakono owotcherera malo okhala ndi makina a PLC amalola kusunga ndi kubwereza ma seti abwino kwambiri kuti agwirizane.
Mapeto
Zinthu zitatu zazikuluzikulu-zowotcherera magetsi, nthawi, ndi kuthamanga kwa ma elekitirodi{1}}zimatsimikizira momwe ntchito iliyonse ikuyendera. makina kuwotcherera malo. Podziwa kuyanjana kwawo, opanga amatha kupeza ma welds amphamvu, oyera osagwiritsa ntchito mphamvu zochepa komanso mtengo wogwirira ntchito. Masiku ano opanga zinthu mwanzeru, kugwiritsa ntchito bwino-makina owotchera malo oyendetsedwa bwino okhala ndi zoikamo zolondola ndikofunikira kuti mukhalebe opambana.
