Mid-frequency yakananga ikozvino (MFDC) welding uye alternating current (AC) welding maviri anowanzo shandiswa welding process, imwe neimwe iine maitiro ayo.Muchikamu chino, tichaongorora pamwe chete kuti ndeipi ine ruoko rwepamusoro: MFDC welding kana AC welding?
Working Principles:
MFDC/Inverter Welding Machine:
Chekutanga, matatu-chikamu AC voltage inopfuura nepainogadziridza yekusefa.
Kechipiri, IGBT switches inoshandura iripo kuita yepakati-frequency ikozvino ye1000 Hz uye yoiendesa kune welding transformer.
Chekupedzisira, epamusoro-simba rectifier diode anoburitsa welding ikozvino yakagadzikana yakananga ikozvino (DC).
AC Welding Machine:
Iko kupinza kwesimba ndeye AC, iyo, mushure mekupfuura nepakati pesimba rekuchinja, inopinda mukati medunhu guru uye control circuit.
Transformer inodzika pasi pe-high-voltage AC kune yakaderera-voltage AC inokodzera welding.AC ikozvino inochinjana pakati pezvakanaka nezvakaipa, ichigadzira kupisa sezvo ichipfuura nepakati petsvimbo yewelding uye workpiece, nekudaro ichinyungudutsa welding zvinhu uye kuwana welding.
Zvakanakira zveMFDC Welding pamusoro pe AC Welding:
Kugadzikana Kwepamusoro:
MFDC weldinginozivikanwa pasirese seimwe yemhando yepamusoro-yekupedzisira kuramba welding zvigadzirwa, inosimudzira kugadzikana panguva yewelding.Yayo yehushamwari welding process paramita uye yakafara kuchinjika huwandu hwechipiri ikozvino inochengetedza inogara iripo, ichipa tarisiro yakakura kupfuura AC welding.
Iyo MFDC magetsi sosi inoburitsa mashoma waveform, kudzivirira zvazvino peak kukanganisa uye kuderedza kupuruzira panguva yewelding.
Kugadziriswa kweMFDC welding current kunoitika pamwero we1000 times per sekondi, kuwana millisecond-level precision, iyo inodarika ka20 kwakaringana kupfuura yechinyakare AC welding machines.
MFDC welding haina kukanganiswa nechimiro uye zvinhu zveiyo workpiece, kubvisa inductive kurasikirwa.
Kunyatsogona:
Michina yewelding yeMFDC inowana simba remagetsi rinopfuura makumi mapfumbamwe nesere muzana, nepo michina yeAC yakatenderedza 60%, zvichiratidza kuvandudzwa kwakanyanya muMFDC welding.
Mari Yekushandisa Yakaderera:
Nekuda kwekuwedzera kwekutanga kukosha kwewelding ikozvino, chaiyo welding nguva inopfupikiswa neinopfuura 20%, zvichideredza zvakanyanya kudiwa kwewelding pressure.
Izvo zvinodikanwa zvemagetsi efekitori zvakaderera, ingangoita 2/3 yeAC welding michina, uye kunyangwe nekuchinja kwemagetsi emagetsi emagetsi, MFDC welding michina inogona kuramba ichinyatso kudzora welding ikozvino.
Naizvozvo, kushandiswa kwesimba kweMFDC welding machine kwakadzikira zvakanyanya, kuwana simba rekuchengetedza rinopfuura 40%.Pamusoro pezvo, kushandisa seti nhatu dzemitoro yakaenzana kunovimbisa kuti hapana boka rinoremerwa, richizadzisa zvinodiwa zvekuchengetedza simba rehupfumi.
Huremu:
Kuenzaniswa neAC welding michina, iyo welding transformer yeMFDC michina yakareruka, ichiita kuti midziyo iwedzere kutakurika uye nyore.Inorema chikamu chimwe chete muzvitatu chehuremu hwe AC transformer uye vhoriyamu, inokodzera marobhoti welding masisitimu.
Inoenderana Nezvakatipoteredza:
Kubvisa kusvibiswa kune magetsi, MFDC welding inzira yakasvibira welding iyo isingade yakasarudzika magetsi uye inogona kushandiswa pamwe chete nemarobhoti welding fixture control system.
Muchidimbu, MFDC welding inodarika AC welding maererano nekugadzikana kwewelding, mhando, kushanda zvakanaka, kuchengetedza simba, midziyo isingaremi, uye kuderedzwa kwemagetsi zvinodiwa pamagetsi emagetsi.
Agera inopa huwandu hwakazara hwepakati-frequency spot welding michina, ine MFDC resistance welding tekinoroji inosvika padanho repasi rose.Iyo yakanyanya kupfupi-yedunhu ikozvino inosvika 250,000 amperes, inoshandiswa zvakanyanya muakasiyana simbi alloy, yakakwirira-simba simbi, inopisa-yakaumbwa simbi, uye aluminium alloy spot welding process, inopa yakakwirira-yekupedzisira masevhisi uye yakavimbika masevhisi kumakambani mazhinji ane mukurumbira pasi rose Fortune 500. .
