Kwinkalo yokwenziwa kwemizi-mveliso yanamhlanje,medium frequency spot weldersziye zaba zizixhobo ezingundoqo kumashishini afana nokuvelisa iimoto, ukuveliswa kwezixhobo zasekhaya, kunye nokulungiswa kwesinyithi ngenxa yokusebenza kwazo ngokufanelekileyo kunye nokuchanekileyo. Nangona kunjalo, uninzi lwabasebenzisi basenemibuzo malunga nokuba zisebenza njani i-medium frequency spot welders, ngakumbi malunga nepateni yotshintsho lwangoku{1}}ngokukodwa, ngeliphi inqanaba lenkqubo yokuwelda iincopho zangoku. Lo mbandela awuhambelani kuphela nomgangatho we-welding kodwa uchaphazela ngokuthe ngqo ukusetyenziswa kwamandla kunye nobomi besixhobo. Eli nqaku liza kubonelela ngo{4}}uhlalutyo olunzulu lwepateni yokwahluka kwangoku kwiiwelder zendawo ezijikelezayo ukusuka kwimigaqo yobugcisa kunye neembono zokusebenza.
I. Umgaqo wokuSebenza kunye neempawu zangoku ze-Medium Frequency Spot Welders
- Medium frequency spot welders zisebenzisa medium frequency inverter technology ukuguqula usetyenziso amandla AC (50/60Hz) ibe medium frequency frequency DC amandla (ngokuqhelekileyo 1kHz-4kHz), nto leyo ke iguqulelwe kwimveliso yangoku ephezulu. Xa kuthelekiswa ne-welders yendabuko ye-AC, imveliso yabo yangoku izinzile, isantya sokuphendula sikhawuleza, kwaye ivumela ulawulo oluchanekileyo lwamandla we-welding.
- Kule nkqubo, utshintsho lwangoku kwi-amedium frequency spot welderayisasazwanga ngokufanayo kodwa ilungiswa ngokuguquguqukayo ngokwenqanaba le-welding. Inkqubo engundoqo inokwahlulwa ibe ngamanqanaba amathathu:
- Inqanaba lokucudisa:Ii-electrodes ziqhagamshelana nee-workpieces, zisebenzisa uxinzelelo lokuphelisa izithuba. Okwangoku kweli nqanaba lincinci kakhulu okanye lizero.
- Inqanaba leWeld:I-electrodes inamandla, kwaye okwangoku iphakama ngokukhawuleza kwixabiso elimiselweyo ukufezekisa ukudibanisa kwesinyithi.
- Bamba inqanaba:I-current inqunyulwa, kodwa uxinzelelo luyagcinwa ukuqinisekisa ukuba i-weld nugget iyaqina.
- Isiphelo esingundoqo:Iincopho zangoku ngexesha leweld stage, kwaye ubude bexesha bufutshane kakhulu (ngokuqhelekileyo iimillisecond ezimbalwa ukuya kumakhulu ambalwa emillisecond). Lo msinga uphezulu ngoko nangoko yimeko engundoqo yokwenza i-weld nugget ephezulu{{1}.
II. Indlela yokuSeka kunye neMiba ePhembelelayo yePeak yangoku
- Ngexesha lokusebenza kwe-amedium frequency spot welder, ukwenzeka kwencopho yangoku kuhambelana ngokusondeleyo nezi zinto zilandelayo:
IiPropati zeMathiriyeli kunye neeMfuno zeWelding
- Ukunyanzeliswa kwesinyithi:Izinto eziphathekayo ezine-resistiveivity ephezulu (umz., insimbi engenasici) zivelisa ubushushu obuninzi phantsi kombane ofanayo, onokuthi ufune ubude obufutshane bexesha langoku ukuphepha ukushisa.
- Ukutyeba kwephepha:Izixhobo zokusebenza ezityebileyo zifuna umsinga ophezulu ukuze zingene kumaleko esinyithi. Ngokomzekelo, i-welding 2mm sheet sheet inokufuna i-peak current edlula i-10kA, ngelixa i-welding sheet encinci inokufuna kuphela i-2kA-5kA.
Izicwangciso zeParameter yeZixhobo
- Cwangcisa Ngoku kunye nexesha:Abaqhubi kufuneka babeke i-peak current kunye nobude bayo ngokweemfuno zenkqubo. Ngokomzekelo, kwi-welding ye-automotive body, i-peak current isetelwe kwi-8kA kunye nobude be-20ms.
- Amandla e-Electrode:Amandla angonelanga anyusa ukuxhathisa koqhagamshelwano, efuna umsinga ophezulu wembuyekezo; amandla agqithisileyo angayityumza i-workpiece, efuna umbane ophantsi.
- Iimpawu zokuPhendula eziNgqobileyo
I-inverter ye-medium frequency spot welder inokusabela kwiinguqu zangoku ngaphakathi kwe-1ms, iqinisekisa ukunyuka ngokukhawuleza kwi-preset peak ngexesha le-weld stage. Lo msinga uphezulu ngephanyazo ugxininisa amandla okunyibilikisa isinyithi ngelixa unciphisa ubushushu{2}}indawo echaphazelekileyo kwaye ikhusela uguquko lweworkpiece.
III. Iingcebiso zokuSebenza zokuphucula iPeak yangoku
Ukuphakamisa ngokupheleleyo ukusebenza kwe-amedium frequency spot welder, abaqhubi kufuneka banikele ingqalelo kula manqaku asebenzayo alandelayo:
UkuTyaniswa okuchanekileyo kweeParamitha zeNkqubo
- Qinisekisa ijika langoku-lexesha lezinto ezahlukeneyo ngovavanyo. Umzekelo, i-aluminium welding ifuna imowudi "yangoku ephezulu, ixesha elifutshane", ngelixa amashiti ensimbi afuna ixesha elongeziweyo lokunciphisa i-oxidation yomhlaba.
- Sebenzisa iisistim zokujonga umgangatho we-welding (umzekelo, ubhaqo wokuxhathisa okuguquguqukayo) ukunika ingxelo yokwenyani{2}}ngexesha lokuba ingaba incopho yangoku iyadibana nemigangatho.
Lawula imeko ye-Electrode
- Uhlambulule rhoqo iingcebiso ze-electrode ukuze ugweme ukuchasana nokunyuka koqhagamshelwano ukusuka kwiingqimba ze-oxide okanye ukungcola, oku kunokukhokelela ekunyukeni okungaqhelekanga kwimfuno yangoku.
- Sebenzisa amanzi{0}}uyilo lwe-electrode olupholileyo ukunqanda imathiriyeli ye-electrode ekuthambeni phantsi kwamaqondo obushushu aphezulu, nto leyo echaphazela ukuzinza koxinzelelo.
ULondolozo lweZixhobo kunye nokuLinganisa
- Ukuhlola inyanga nenyanga ukusebenza kwe-inverter yeemodyuli ze-inverter kunye ne-transformers ukuqinisekisa ukuchaneka kwemveliso yangoku.
- Linganisa abenzi boluvo bangoku ukunqanda ukutenxa kweyona ncopho yokwenyani ukusuka kwixabiso elibekiweyo ngenxa yeempazamo zokulinganisa.
IV. Imingcipheko kunye nokuThintelana neNcopho eNgaqhelekanga yangoku
Ukuba incopho yangoku yemedium frequency spot welder ingalawuleki, inokubangela ezi ngxaki zilandelayo:
- I-Weld Overburn:Ukugqithiswa kwangoku okanye ixesha elide kakhulu kubangela ukunyibilika kwesinyithi, okukhokelela kwi-voids okanye iintanda.
- Isinxibo seZixhobo:Umsebenzi oqhubekayo wokulayisha ngaphezulu unciphisa ubomi be-inverter kunye nokwandisa iindleko zokulondoloza.
- Inkcitho yamandla:Incopho yangoku ngokungeyomfuneko yonyusa iindleko zombane, ibe nefuthe elibonakalayo-kwimveliso emikhulu.
Izisombululo:
- Yazisa i-algorithms yolawulo oluguqukayo ukulungelelanisa ngoku ngokusekwe kwiimeko zokusebenza.
- Cwangcisa imisebenzi ye-alarm yangoku yokuphazamisa ngokukhawuleza iinkqubo ezingaqhelekanga ze-welding.
Ukuqukumbela
Incopho yangoku ye-medium frequency spot welder igxininiswe kwinqanaba le-weld, kwaye ubukhulu bayo kunye nobude bayo bubonisa ngokuthe ngqo umgangatho we-welding. Ngokumisela ngokwenzululwazi iiparamitha kunye nokugcina ngokungqongqo izixhobo, iinkampani azinakuphucula kuphela imveliso yemveliso kodwa zinciphisa ukusetyenziswa kwamandla kunye neendleko. Ngophuhliso lweteknoloji yolawulo olukrelekrele, ulawulo lwangoku kwixesha elizayo kwimedium frequency spot weldersiya kuba ichaneke ngakumbi, iqhubela phambili ngakumbi ukwenziwa kwemveliso ukuya kwimpumelelo enkulu kunye nozinzo.
