Metal sheet kuwotcherera ndi gawo lofunikira kwambiri popanga zinthu zosiyanasiyana zazitsulo. Spot kuwotcherera kumagwiritsidwa ntchito kwambiri m'makampani opanga magalimoto, makampani opanga zida zapanyumba, komanso makampani opanga ma sheet metal box. Ukadaulo wamakono umafuna kuchulukirachulukira kwaukadaulo wowotcherera. M'nkhaniyi, tifotokoza ndondomeko kuwotcherera malo mwatsatanetsatane ndi kukambirana ubwino wakuwotcherera malom'makampani opanga magalimoto.

Kodi Spot Welding ndi chiyani

Spot kuwotcherera ndi mtundu wakukana kuwotcherera. Zimaphatikizapo kuyika zida ziwiri zogwirira ntchito pakati pa maelekitirodi apamwamba ndi apansi, kuziwotcha ndi magetsi, ndikugwiritsa ntchito mphamvu kuti apange pulasitiki pamalo okhudzana ndi zogwirira ntchito, kuwalola kuti azigwirizana. Mfundo yake ndi yophweka: poyendetsa magetsi kupyolera mu maelekitirodi awiri amkuwa, kukana kumawonjezera kutentha kwa ntchito zogwirira ntchito, zomwe zimapangitsa kuti zisungunuke ndi kugwirizana pamodzi. Ndicho chifukwa chake amatchedwanso resistance kuwotcherera. Poyerekeza ndi zinakuwotcherera njira, kuwotcherera malo sikufuna kuwonjezera zinthu zowotcherera, ndipo ntchito yake ndi yosavuta.

Momwe Mungapezere Weld?

1: Kuyeretsa Pamwamba Pantchito

Spot Welding Zambiri Zida

Aluminiyamu: Aluminiyamu ndi wamba kwambiri kuwotcherera malo, makamaka makampani magalimoto, kumene makhalidwe ake opepuka akhoza m'malo nyumba okhwima. Komabe, kuwotcherera aluminiyamu kumakhala kovuta kwambiri chifukwa cha kukhathamiritsa kwake kwakukulu, komwe kumafuna kuwirikiza kawiri kuchuluka kwa zida wamba. Choncho, pamene kuwotcherera aluminiyamu, muyenera kusankha zida ndi mphamvu apamwamba.

Chitsulo: Chitsulo ndiye chinthu chodziwika kwambiri pakuwotcherera malo. Ndizinthu zolimba, ndipo zida zambiri zamagalimoto zimagwiritsa ntchito chitsulo. Spot kuwotcherera nthawi zambiri amagwiritsidwa ntchito kuwotcherera matupi agalimoto ndi zida zolimba za mtedza.

Mkuwa: Spot kuwotcherera mkuwa kumafuna njira zapadera. Copper imakhala ndi matenthedwe apamwamba komanso magetsi, zomwe zimapangitsa kuti zisamangomamatira ku maelekitirodi. Choncho, timasankha tungsten kapena molybdenum electrodes. Pakuwotcherera, zida zowotcherera zimafunika kuwonjezeredwa pakati pazigawo ziwirizi, kotero kuti brazing yamkuwa imagwiritsidwa ntchito kwambiri.

Chitsulo chagalasi: Kuwotcherera chitsulo kanasonkhezereka ndi kovuta kuposa kuwotcherera zitsulo, amafuna apamwamba panopa. Malo osungunuka a zokutira zamalata ndi otsika kuposa zitsulo, choncho zimakhala zosavuta kusefukira ndikupanga splashes panthawi yowotcherera.

Workpiece Surface Cleaning

Musanayambe kuwotcherera, ndikofunikira kuyang'ana ngati zogwirira ntchito zili ndi dzimbiri kapena oxidation. Ngati atero, zogwirira ntchito ziyenera kuthandizidwa. Mukhoza kugwiritsa ntchito sandpaper kapena chopukusira kuti pamwamba pakhale bwino. Apo ayi, padzakhala splatter yambiri, yomwe ingakhudze khalidwe la kuwotcherera.

2: Ganizirani Zosintha Zina 4 Musanawotchere Ndi Kukhazikitsa Magawo

Kupanikizika

Kusankha kukakamiza koyenera ndikofunikira. Ngati ma elekitirodi akuthamanga kwambiri kapena otsika kwambiri, amatha kufooketsa mphamvu ya weld ndikuwonjezera kubalalitsidwa kwake. Pamene kuwotcherera, ndikofunika kuganizira makhalidwe a workpiece poika kukakamiza.

Nthawi Yowotcherera

Kukhazikitsa nthawi yoyenera kuwotcherera ndikofunikira. Ngati nthawi yowotcherera ndi yochepa kwambiri, chogwirira ntchito sichingasungunuke mokwanira kuti chikwaniritse zofunikira zowotcherera. Komano, ngati nthawi kuwotcherera ndi yaitali kwambiri, workpiece sachedwa mapindikidwe, kumabweretsa zizindikiro zazikulu weld.

Welding Current

Kuwotcherera pakali pano ndi nthawi zimathandizirana, koma zilinso ndi malire. Kupeza bwino pakati pa ziwirizi ndikofunika kwambiri kuti mupange ma welds abwino.

3: Spot Welding Machine

Zipangizo zofunika kuwotcherera malo ndimakina kuwotcherera malo, yomwe imabwera mumitundu yosiyanasiyana. Kusankha malo oyenera kuwotcherera makina zimatengera mawonekedwe a workpiece ndi zofunika kuwotcherera. Mwachitsanzo, ngati mukufuna kuwotcherera pamodzi mbale ziwiri zosapanga dzimbiri 2mm kuti mukwaniritse mphamvu zakuthupi za makolo, muyenera kusankha makina owotcherera omwe ali ndi mphamvu zapamwamba. Makina owotcherera omwe ali ndi 130KVA amatha kuchita izi. Komabe, ngati mukufuna kuwotcherera mbale 2mm wandiweyani zotayidwa, muyenera muyezo malo kuwotcherera makina ndi 260KVA.

4: Ikani Chogwirira Ntchito Pakati Pa Ma Electrodes Ndikuyamba Kuwotcherera

Mukasankha makina owotcherera a malo oyenera, ndi nthawi yoti muyambe kuwotcherera. Mutatha kulumikiza magetsi ndikusintha magawo, ikani chopangira chokonzekera pakati pa ziwirizikapu ya electrode. Dinani batani lopondaponda la phazi, ndipo maelekitirodi adzakankhira pansi, kutenthetsa ndi kukanikiza zogwirira ntchito, potero kulumikiza mfundo zamagulu awiriwo pamodzi.

5: Mayeso a Peel Pambuyo Kuwotcherera

Pambuyo kuwotcherera workpiece, ndizovuta kuwunika mphamvu ya weld ndi maso amaliseche okha. Ndipamene muyenera kugwiritsa ntchito zida kuyesa mphamvu weld. Kuyeza peel ndi njira yabwino kwambiri. Poyesa ma peel, onani mphamvu yayikulu yofikira pakusenda chogwirira ntchito. Zina zogwirira ntchito zili ndi zofunikira zenizeni za mtengowu kuti ziwone kuti weld ndiyovomerezeka.

Ubwino Wa Spot Welding For Automotive Industry

Zolumikizana Zolimba Komanso Zokhalitsa

Mbali zowotcherera pogwiritsa ntchito kuwotcherera kukana kumapanga mfundo zolimba komanso zolimba. Zopangidwa motere ndi zolimba komanso zokhazikika, zomwe ndizofunikira kwambiri pamsika wamagalimoto. Mwachitsanzo, mtedza ukapanda kuwotcherera bwino, ukhoza kuyambitsa ngozi pamsewu. Kulondola ndi kudalirika ndizofunikira kwambiri m'gawo lamagalimoto, pomwe ngakhale cholakwika chaching'ono sichimaloledwa. Chifukwa chake, resistance welding imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti mfundozi zikukwaniritsidwa.

Kufanana M'malo Olumikizirana mafupa

Mu kuwotcherera zigawo magalimoto, sikofunikira kuti welds kukhala amphamvu komanso kuti welded mankhwala kuoneka aesthetically zokondweretsa. Kukaniza kuwotcherera kumatha kukwaniritsa izi. Makamaka pakuwotcherera thupi lagalimoto, nsonga iliyonse yowotcherera iyenera kukhala yosawoneka bwino, chifukwa imakhudza kukonzanso kotsatira komanso mawonekedwe onse agalimoto.

Kulumikizana Kwa Zinthu Zosiyana

Kukaniza kuwotcherera ndikoyeneranso kuwotcherera zinthu zosiyanasiyana. M'makampani opanga magalimoto, pali zigawo zomwe zitsulo zosiyanasiyana zimafunikira kulumikizidwa palimodzi. Apa ndipamene kuwotcherera kukana kumakhala kothandiza, chifukwa kumatha kulumikizana ndi zinthu zosiyanasiyana, monga chitsulo ndi aluminiyamu.

Kuwotcherera Kuthamanga

Resistance kuwotcherera sikufuna filler waya. Imafulumira kuwotcherera tizigawo tating'ono. M'makampani opanga magalimoto, pomwe zigawo zing'onozing'ono zimawotcherera, njirayi ndi yachangu komanso yosavuta kugwiritsa ntchito, kupulumutsa ntchito komanso kukulitsa luso la kuwotcherera.

Kubwerezabwereza

Chifukwa choyenerera kuwotcherera zinthu zobwerezabwereza, kuwotcherera kukana kungafunike kusintha magawo ndi zida posinthira kuzinthu zosiyanasiyana. Chifukwa chake, ndiyoyenera kuwotcherera zinthu zamphamvu kwambiri. Zida zamagalimoto, ndendende chifukwa chamtunduwu, zimapeza kuwotcherera kukana makamaka koyenera makampani amagalimoto.

Resistance welding ikugwiritsidwa ntchito kwambiri m'mafakitale amasiku ano. Ukadaulo wake umasinthidwa mosalekeza kuti ugwirizane ndi chitukuko cha mafakitale, kupita ku automation. Kuti mudziwe zambiri za resistance welding, chonde tsatirani zosintha zathu.
