Kodi mukudziwa za Dynamic Resistance Curve mu Medium Frequency Inverter Spot Welding Machine?

Mphamvu yopindika yopingasa ndi gawo lofunikira pamakina owotcherera ma frequency inverter spot. Zimayimira mgwirizano pakati pa kuwotcherera pano ndi kutsika kwamagetsi pamagetsi panthawi yowotcherera. Kumvetsetsa kupindika kumeneku ndikofunikira pakukhathamiritsa magawo azowotcherera ndikuwonetsetsa kuti ma welds apamwamba kwambiri. M'nkhaniyi, tikambirana za dynamic resistance curve ndi kufunikira kwake pakugwiritsa ntchito kuwotcherera mawanga.

1. Tanthauzo la Dynamic Resistance Curve: Njira yokhotakhota yamphamvu ikuwonetsa kukana komwe kumakumana ndi nthawi yowotcherera. Imapezedwa popanga chiwembu chowotcherera pano motsutsana ndi kutsika kwamagetsi pama electrode. Mzerewu umapereka zidziwitso zofunikira pamayendedwe amagetsi ndi matenthedwe a weldment, kulola kuwongolera bwino ndikuwunika momwe kuwotcherera.
2. Zinthu Zomwe Zimakhudza Mapiritsi Amphamvu: a. Katundu Wazinthu: Mapiritsi osunthika amasiyanasiyana ndi zida zosiyanasiyana chifukwa cha kusinthika kwamagetsi, kutulutsa kwamafuta, komanso kutentha kosungunuka. Ndikofunikira kuganizira zakuthupi potanthauzira pamapindikira ndikuzindikira magawo oyenera kuwotcherera. b. Kukonzekera kwa Electrode: Maonekedwe, kukula, ndi zinthu za maelekitirodi zimakhudza malo okhudzana ndi kutentha kwa kutentha, zomwe zimakhudzanso mayendedwe otsutsa. Kusankha ndi kukonza ma electrode moyenera ndikofunikira kuti mupeze zotsatira zokhazikika komanso zodalirika zowotcherera. c. Kuwotcherera Parameters: Mzere wokhotakhota wokhazikika umakhudzidwa ndi kusintha kwa magawo owotcherera monga kuwotcherera pakali pano, mphamvu ya electrode, ndi nthawi yowotcherera. Kusintha magawowa kumatha kusintha mawonekedwe ndi mawonekedwe a curve, kulola kukhathamiritsa kwa njira yowotcherera.
3. Kufunika kwa Curve ya Dynamic Resistance Curve: a. Kuyang'anira Njira: Mzere wokhotakhota wokhazikika umapereka ndemanga zenizeni zenizeni pazabwino komanso kukhazikika kwa njira yowotcherera. Kupatuka kwa mawonekedwe opindika omwe amayembekezeredwa kumatha kuwonetsa zovuta monga kusalumikizana bwino kwa ma elekitirodi, kusapanga kutentha kosakwanira, kapena kuphatikiza kolakwika kwa zinthu. b. Kukhathamiritsa kwa Parameter: Posanthula mayendedwe olimbikira, magawo oyenera kuwotcherera amatha kutsimikizika kuti akwaniritse zomwe mukufuna, monga kuya kwa kulowa, kukula kwa nugget, ndi mphamvu zolumikizana. Kuwongolera bwino magawo owotcherera potengera kusanthula kwa ma curve kumathandizira kuwongolera njira ndikuwonetsetsa kuti weld amakhazikika. c. Kuzindikira Zolakwa: Kusintha kwadzidzidzi kapena zosokoneza pamayendedwe osunthika amatha kuwonetsa kuvala kwa ma electrode, kuipitsidwa kwazinthu, kapena zolakwika zina. Kuwunika kokhotakhota kumathandizira kuzindikira koyambirira kwa zovuta izi, ndikupangitsa kukonza nthawi yake kapena kukonza zinthu kuti zipewe kuwonongeka kwa kuwotcherera.
4. Njira Zoyezera: Njira zosiyanasiyana zingagwiritsidwe ntchito kuyeza ndi kusanthula mayendedwe osunthika, kuphatikiza kuyang'anira kutsika kwamagetsi, njira zamakono zowonera, ndi makina opezera deta. Njirazi zimagwira ntchito yamagetsi nthawi yomweyo panjira yowotcherera ndikupangitsa kuti pakhale njira yolimbikitsira yopingasa.

Mphamvu yopingasa yokhotakhota pamakina apakati pafupipafupi inverter spot kuwotcherera ndi chida chofunikira pakumvetsetsa momwe magetsi ndi matenthedwe amagwirira ntchito. Imakhala ngati chiwongolero chowongolera magawo owotcherera, kuyang'anira kukhazikika kwa njira, ndikuzindikira zolakwika zomwe zingachitike. Pogwiritsa ntchito zambiri zomwe zimaperekedwa ndi ma curve of resistance curve, opanga amatha kupeza ma welds okhazikika komanso apamwamba kwambiri, kupititsa patsogolo zokolola zonse komanso kudalirika kwazinthu pazowotcherera.
