Electric Resistance Spot Spot Welding panthawi ya Power Heating Phase

Electric resistance spot kuwotcherera ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga pomwe zidutswa ziwiri kapena zingapo zazitsulo zimalumikizidwa palimodzi pogwiritsa ntchito kutentha ndi kukakamiza. M'nkhaniyi, tiwona gawo lofunika kwambiri la ndondomekoyi - gawo la kutentha kwa mphamvu.

Kumvetsetsa Electric Resistance Spot Welding

Kuwotcherera kwa malo amagetsi, komwe nthawi zambiri kumadziwika kuti kuwotcherera, kumaphatikizapo kugwiritsa ntchito magetsi kuti apange kutentha polumikizana pakati pa zitsulo ziwiri. Njirayi imagwiritsidwa ntchito nthawi zambiri m'mafakitale oyendetsa magalimoto, ndege, ndi zomangamanga kuti apange ma welds amphamvu komanso odalirika.

Gawo la Kutentha kwa Mphamvu

Gawo lotenthetsera mphamvu ndi gawo lofunikira kwambiri pakuwotcherera malo. Panthawi imeneyi, mphamvu yapamwamba imadutsa mu electrode, yomwe imakhudzana mwachindunji ndi mapepala achitsulo kuti agwirizane. Kukaniza kwamagetsi pamalo olumikizana kumapangitsa kutentha kwambiri, zomwe zimapangitsa kuti chitsulocho chisungunuke ndikuphatikizana.

Mfundo zazikuluzikulu panthawi ya Kutentha kwa Mphamvu

1. Kuwongolera kwapano ndi Voltage: Kuwongolera molondola kwapano ndi magetsi ndikofunikira panthawi yotentha mphamvu. Izi zimatsimikizira kuti kutentha koyenera kumapangidwa, kuteteza kutentha kapena kutentha kosakwanira.
2. Electrode Design: Mapangidwe a ma elekitirodi ndi ofunikira kuti akwaniritse bwino weld. Zida zama elekitirodi oyenerera ndi mawonekedwe amasankhidwa kuti athandizire kutumiza kutentha koyenera komanso kuchepetsa kuvala kwa ma elekitirodi.
3. Nthawi Yowotcherera: Kutalika kwa gawo la kutentha kwa mphamvu, komwe kumatchedwa weld time, kumayendetsedwa mosamala. Nthawi zambiri imakhala kachigawo kakang'ono ka sekondi koma imatha kusiyanasiyana kutengera zinthu ndi makulidwe omwe amawotcherera.
4. Kuziziritsa: Pambuyo pa gawo lotenthetsera mphamvu, gawo lozizirira limatsatira kulimbitsa weld. Kuziziritsa kungaphatikizepo kugwiritsa ntchito madzi kapena njira zina zoziziritsira kuteteza kutentha kwambiri.

Ubwino wa Electric Resistance Spot Welding

• Liwiro: Spot kuwotcherera ndi njira yofulumira, yomwe imapangitsa kuti ikhale yoyenera kupanga kwambiri.
• Kusasinthasintha: Mukakhazikitsidwa bwino, kuwotcherera pamalo kumapereka zowotcherera mosasinthasintha komanso zodalirika.
• Mphamvu: Zotsatira zake zimakhala zolimba, nthawi zambiri zimakhala ndi zinthu zofanana ndi zitsulo zoyambira.
• Ukhondo: Spot kuwotcherera kumatulutsa utsi wochepa, utsi, kapena zinthu zina zomwe zimachokera kunja, zomwe zimapangitsa kuti zisawonongeke.

Mavuto ndi Kulingalira

Ngakhale kuwotcherera kwa malo amagetsi kumapereka zabwino zambiri, sikuli kopanda zovuta zake. Kusamalira bwino zida, chisamaliro cha ma elekitirodi, komanso kuphunzitsidwa kwa ogwiritsa ntchito ndikofunikira kuti mukwaniritse ma welds apamwamba nthawi zonse. Kuphatikiza apo, kuwotcherera mawanga sikungakhale koyenera pazinthu zonse kapena makulidwe.

M'dziko lazopanga, kuwotcherera kwa magetsi pa nthawi yotenthetsera mphamvu ndi njira yofunikira kwambiri yolumikizira zitsulo moyenera komanso moyenera. Kumvetsetsa zovuta za gawoli, kuphatikiza kuwongolera kwamakono ndi magetsi, kapangidwe ka electrode, nthawi yowotcherera, ndi kuziziritsa, ndikofunikira kuti mupange ma welds amphamvu komanso odalirika. Akagwiritsidwa ntchito moyenera, kuwotcherera kwa malo amagetsi kumathandizira kupanga zinthu zolimba komanso zotetezeka m'mafakitale osiyanasiyana.
