Resistance spot welding inzira yakakosha inoshandiswa mumaindasitiri akasiyana ekubatanidza simbi pamwechete. Kuti uwane emhando yepamusoro welds, kunyatso kudzora pamusoro peiyo welding paramita kwakakosha. Imwe yakakosha parameter ndeye pre-kudzvanywa nguva, iyo inoita basa rakakosha mukuona kutendeseka kweiyo weld. Muchinyorwa chino, isu tichakurukura nzira yekuenzanisa iyo pre-kudzvanywa nguva muresitorendi nzvimbo welding michina.
Resistance spot welding inosanganisira kushandiswa kwemagetsi emagetsi kugadzira kupisa kwenzvimbo panzvimbo yewelding, inoteverwa nekushandiswa kwe mechanical pressure yekubatanidza masimbi maviri pamwechete. Iyo pre-pressure nguva ndiyo nguva iyo ma electrode anoshandisa kumanikidza kune workpieces pamberi peiyo welding ikozvino yaiswa. Iyi nguva yakakosha sezvo ichigadzira zvinhu zvewelding nekunyorovesa kana kuchenesa nzvimbo dzadzo.
Kukosha kwePre-Pressure Time
Nguva yepre-pressure ine simba guru pahutano uye simba re weld. Kana nguva yepre-pressure ipfupi, zvinhu zvacho zvingasave zvakanyoroveswa kana kucheneswa, zvichiita kuti weld isina simba ipinde. Kune rumwe rutivi, kana nguva yepre-pressure yakarebesa, inogona kutungamira mukupisa kwakanyanya uye deformation yezvishandiso, zvichikonzera kukanganisa uye kukanganisa kutendeseka kwemubatanidzwa.
Calibration Method
Calibrating pre-pre-pressure time inosanganisira yakarongeka nzira yekuona optimal welding mamiriro. Heano matanho ekutevera:
- Machine Setup: Tanga nekumisikidza inodzivirira nzvimbo welding muchina neinodiwa electrode simba, welding ikozvino, uye welding nguva marongero.
- Yekutanga Pre-Pressure Time: Sarudza yekutanga pre-kudzvanywa nguva iri mukati meyakajairwa renji yechishandiso chako. Izvi zvichashanda senzvimbo yekutanga kugadzirisa.
- Welding Test: Ita nhevedzano yebvunzo welds uchishandisa yakasarudzwa pre-pressure nguva. Ongorora kunaka kwewelds maererano nesimba uye chitarisiko.
- Gadzirisa Pre-Pressure Time: Kana nguva yekutanga-pre-pressure nguva inokonzera welds iyo isingasviki, ita zvigadziridzo zvekuwedzera kune pre-pressure nguva. Wedzera kana kuderedza nguva mune zvidiki zviwedzere (semuenzaniso, milliseconds) uye ramba uchiita bvunzo welds kusvika yaunoda weld mhando yawanikwa.
- Monitoring uye Zvinyorwa: Munguva yese yekugadzirisa, nyatso tarisisa mhando ye weld uye rekodha pre-kudzvanywa nguva zvigadziriso zvebvunzo yega yega. Mapepa aya achakubatsira kuti utarise magadzirirwo akaitwa uye mhedzisiro yawo inoenderana.
- Optimization: Kana uchinge waona pre-kudzvanywa nguva iyo inogara ichigadzira emhando yepamusoro welds, iwe wakabudirira kuyera inopikisa nzvimbo welding muchina wekushandisa kwako chaiko.
Kugadzirisa iyo pre-kudzvanywa nguva muresitorendi nzvimbo welding michina idanho rakakosha mukuona kugadzirwa kwemhando yepamusoro welds. Nekugadzirisa zvakarongeka uye kuyedza iyo pre-kudzvanywa nguva, unogona kukwidziridza iyo welding maitiro kune yako chaiyo zvinhu uye mashandisiro, zvichitungamira kune akasimba, akavimbika welds. Kugadzirisa kwakaringana hakungokwidziri weld mhando asi zvakare kunoderedza mukana wekuremara uye kugadzirisa zvakare, pakupedzisira uchivandudza mashandiro uye mutengo-unoshanda wekuita kwako welding.
