Kodi Njira Zazikulu Zotani Pakugwirira Ntchito Kwa Makina Owotcherera Anthawi Yapakatikati Pakali pano?

Makina owotcherera apakati pafupipafupi omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana polumikiza zitsulo palimodzi.Makinawa amatenga gawo lofunikira pakuwonetsetsa kuti zinthu zambiri zimakhala zolimba komanso zolimba, kuyambira zida zamagalimoto mpaka zida zapakhomo.Kuti timvetsetse bwino momwe makinawa amagwirira ntchito, tiyeni tifufuze masitepe ofunika kwambiri pantchito yawo.

1. Magetsi: Gawo loyamba pakugwira ntchito kwa makina owotcherera apakati-pafupipafupi omwe ali pano ndikuwapatsa mphamvu yokhazikika.Nthawi zambiri, makinawa amafunikira gwero lamphamvu lachindunji (DC), lomwe litha kuperekedwa kudzera m'njira zosiyanasiyana, kuphatikiza zosinthira ndi zosintha.Mphamvu yamagetsi iyenera kuyesedwa mosamala kuti iwonetsetse voteji yoyenera ndi milingo yapano panjira yowotcherera.
2. Clamping: Mphamvu yamagetsi ikakhazikitsidwa, zigawo zachitsulo zomwe zilumikizidwe zimakhazikika bwino.Ichi ndi sitepe yovuta, monga kulinganiza koyenera ndi kukakamizidwa ndikofunikira kuti mukwaniritse chowotcherera cholimba komanso chodalirika.Makina ena amagwiritsa ntchito zingwe zamakina, pomwe ena amagwiritsa ntchito makina a pneumatic kapena hydraulic kuti agwirizanitse mbalizo.
3. Electrode Contact: Chotsatira chimaphatikizapo kubweretsa ma elekitirodi owotcherera kuti agwirizane ndi zitsulo zomwe ziyenera kuwotcherera.Ma elekitirodi awa nthawi zambiri amakhala ndi mkuwa kapena zinthu zina zowongolera ndipo amapangidwa kuti azitumiza magetsi kuzinthu zogwirira ntchito.Mapangidwe oyenera a ma elekitirodi ndi kuyanika ndikofunikira kuti mukwaniritse zowotcherera bwino.
4. Welding Current Application: Ndi ma electrode omwe ali m'malo mwake, makina opangira kuwotcherera amagwiritsa ntchito mphamvu yapamwamba, nthawi zambiri imakhala ngati yachindunji (DC), kumalo olumikizana pakati pa zitsulo.Izi zimatulutsa kutentha kwakukulu, zomwe zimapangitsa kuti zitsulo zisungunuke ndikuphatikizana pamodzi.Kutalika ndi mphamvu ya kayendedwe kameneka kumayendetsedwa mosamala kuti apange mgwirizano wolimba komanso wokhazikika popanda kutenthedwa kapena kuwononga zipangizo.
5. Kuziziritsa ndi Kulimbitsa: Pambuyo pakuwotcherera pakali pano, makinawo nthawi zambiri amakhala ndi njira yozizirira kuti aziziritsa mwachangu malo otsekemera.Izi zimathandiza kulimbitsa chitsulo chosungunuka ndikuchepetsa mapangidwe a zolakwika kapena mawanga ofooka mu weld.Kuziziritsa koyenera ndi kofunikira kuti mukhale ndi weld wapamwamba kwambiri, womveka bwino.
6. Kuwongolera Kwabwino: Pomaliza, msonkhano wowotcherera umayang'aniridwa ndi oyang'anira kuti awonetsetse kuti weld akukwaniritsa zomwe zanenedwa.Izi zitha kuphatikiza kuwunika kowonera, kuyesa kosawononga, kapena njira zina zodziwira zolakwika, ming'alu, kapena kusalongosoka mu weld.Nkhani zilizonse zimayankhidwa kuti zitsimikizire kuti chinthu chomaliza chikukwaniritsa zofunikira komanso magwiridwe antchito.

Pomaliza, makina owotcherera apakati-pafupipafupi pano amatsata njira zingapo zofunika kuti agwirizane ndi zitsulo bwino.Kuchokera pakupanga magetsi okhazikika mpaka kugwiritsa ntchito kuwotcherera pakali pano ndikuwunika zowongolera bwino, sitepe iliyonse imakhala ndi gawo lofunikira popanga ma welds amphamvu komanso odalirika.Kumvetsetsa momwe ntchitoyi ikugwirira ntchito ndizofunikira kwambiri kwa iwo omwe ali ndi mafakitale opanga zitsulo ndi kupanga.
