Kwimveliso yanamhlanje, nokuba ikwizixhobo zeemoto, iipakethi zebhetri zamandla amatsha, okanye iindibano zentsimbi, ukuwelda yinkqubo engundoqo yokujoyina. Njengoko izantya zemveliso zisanda kunye nemigangatho yomgangatho iba ngqongqo, iiwelder ze-AC zemveli ngokuthe ngcembe zitshintshwa ngoomatshini bokuwelda bamabala aphakathi ngenxa yokusebenza kwabo okuphezulu kunye nolawulo olungcono.
Ukuba uceba ukuphucula izixhobo zakho, umbuzo ophambili awungowokuba ukhethe iteknoloji yeMFDC, kodwa ungakhetha njani umatshini wokuwelda amabala aphakathi ohambelana ngokwenene neemfuno zakho zemveliso. Esi sikhokelo silandelayo sichaza iingenelo eziphambili kunye neendlela zokhetho olusebenzayo ngokwemiqathango ecacileyo.
Kutheni oomatshini bokuwelda beNdawo abaPhakathi beFrequency beTshintsha iiWelder zeAC
1. UkuSebenza okuPhakamileyo koMbane kunye neeNdleko zokuSebenza eziphantsi
Iintsimbi ze-AC zemveli zisebenza kwi-50Hz okanye i-60Hz. Umatshini wokuwelda amabala aphakathi usebenzisa itekhnoloji yokuguqula itekhnoloji ukonyusa amaza ukuya malunga ne-1000Hz okanye ngaphezulu, ukuvelisa imveliso yeDC ezinzileyo. Ikhoyo ngoku igudileyo, ubushushu bugxininise ngakumbi, kwaye ukulahleka kwamandla kuyancipha.
Abavelisi abaninzi bafunamedium frequency inverter indawo welding machine ukonga amandlazigxile ekucutheni-indleko zombane zexesha elide. Kwimveliso ephezulu - yevolumu, iinkqubo ze-MFDC zinciphisa ukusetyenziswa kwamandla nge-30% ukuya kwi-50% xa kuthelekiswa noomatshini be-AC besiqhelo. Kwiifektri eziqhuba unyaka{6}umjikelezo, oku kunokukhokelela kulondolozo olubalulekileyo.
Ukongeza, iisistim ze-MFDC zisebenzisa igalelo lesigaba sesithathu-esilungelelanisiweyo, esicutha uxinzelelo kunikezelo lwamandla lwasefektri.
2. Igalelo lobushushu elizinzile ngakumbi kunye nokuNxibelelana kweWeld eNgcono
I-AC welding yangoku yehla ukuya kwi-zero ngexesha lomjikelo ngamnye. Ngokwahlukileyo, imveliso yeMFDC iphantse yaqhubeleka kwaye izinzile. Oku kuvumela i-weld nugget ukuba yenze ngokukhawuleza kwaye ngokulinganayo.
Kwizinto ezifana ne-aluminium alloys kunye neebhasi zebhasi, eziqhuba ubushushu ngokukhawuleza, ukuhanjiswa kwamandla okuzinzile kunye nokugxininiswa kubalulekile. Xa abavelisi bekhangela aUmatshini wokuwelda we-aluminiyam ngokuchaneka okuphezulu, bahlala bezama ukucombulula iingxaki ezinxulumene nomgangatho we-weld ongahambelaniyo obangelwa kukulawulwa kobushushu obungazinzanga. Itekhnoloji yeMFDC ibonelela ngenzuzo ecacileyo kwezi zicelo.
Imiba emihlanu ePhambili ekufuneka iqwalaselwe xa uthenga iSpot Welding Machine
Xa ukhetha umatshini wokuwelda amabala aphakathi, ungagxininisi kumandla alinganisiweyo okanye ixabiso. Umatshini kufuneka uhambelane neemfuno zakho zokuvelisa.
1. Uhlobo lwezinto eziphathekayo kunye nokutyeba kwe-Welding
Izinto ezahlukeneyo zifuna iiparitha ze-welding ezahlukeneyo. Ngaphambi kokuba uqhagamshelane nomthengisi, chaza ngokucacileyo:
- Yeyiphi imathiriyeli oyiweldayo?
- Buthini ubukhulu bomaleko ngamnye?
- Buthini ubunzima obudityanisiweyo bubonke?
Umzekelo, -intsimbi ephezulu kunye nentsimbi ekhandisiweyo ifuna ulawulo oluzinzileyo lwangoku kunye namandla awoneleyo okuthintela ukonakaliswa kwengubo okanye i-weld nuggets ebuthathaka. I-aluminiyam kunye nobhedu zibuchitha ubushushu ngokukhawuleza, ngoko zifuna i-peak ephezulu yangoku kunye nolawulo lokuphendula ngokukhawuleza.
Ukukhetha umthamo ofanelekileyo kuthetha ukuthelekisa umatshini nesicelo sakho, hayi ukukhetha eyona modeli yamandla iphezulu.
2. Ukunyanzeliswa kweNkqubo yokuLawula: I-Pneumatic okanye i-Servo Electric?
Umgangatho we-weld awuxhomekanga kuphela ngoku kodwa nakwi-welding force engaguqukiyo.
- Iisistim zomoya zineendleko-zisebenzayo kwaye zifanele uninzi lwemisebenzi yokwenziwa kwesinyithi ngokubanzi.
- Iinkqubo zombane ze-Servo zivumela ulawulo lwamandla olucwangcisekileyo kunye nokuphendula ngokukhawuleza. Zilungele iindawo ezichanekileyo apho ubunzulu be-indentation kunye ne-deformation kufuneka ilawulwe ngokuqinileyo.
Ukuba imveliso yakho ifuna ukuchaneka okungqongqo komgangatho okanye ukuphawulwa okuncinci komphezulu, inkqubo ye-servo lolona khetho lungcono.
3. Ukulawulwa kokuSebenza kweNkqubo kunye neMbuyekezo ezenzekelayo
Isilawuli ngundoqo wawo nawuphi na umatshini wokuwelda amabala aphakathi. Inkqubo{1}ekumgangatho ophezulu kufuneka iquke ulawulo lwangoku. Oku kuvumela umatshini ukuba ulungelelanise ngokuzenzekelayo imveliso xa i-electrode inxiba okanye iimeko zomphezulu zitshintsha, ukunceda ukugcina amandla e-weld angaguqukiyo.
Xa uphandaindlela yokukhetha umatshini wokuwelda amaza aphakathi, iinjineli zihlala zivavanya ukuba umlawuli uxhasa ukugcinwa kweparameter, ukurekhoda kwedatha yokuvelisa, kunye nemisebenzi ye-alamu. Ezi mpawu zinceda ukugcina umgangatho ozinzile kunye nokwenza lula ulawulo lwenkqubo.
4. Ukuthembeka kweNkqubo yokupholisa
I-Spot welding ivelisa ubushushu obuqinileyo ngexesha elifutshane. Ngaphandle kokupholisa okufanelekileyo, iimodyuli kunye neemodyuli zamandla zinokugqithisa kwaye ziguge ngokukhawuleza.
Xa uvavanya umatshini, qinisekisa:
- Inkqubo yokupholisa ihlanganisa amacandelo abalulekileyo afana ne-transformer kunye neemodyuli zamandla.
- Isekethe yamanzi kulula ukuyigcina.
- Inkqubo ibandakanya ukuhamba kwamanzi okanye ukujonga ubushushu.
Kwiindawo eziqhubekayo zokuvelisa, ukupholisa okuthembekileyo kuchaphazela ngokuthe ngqo ubomi bomatshini kunye nexesha lokuphumla.
5. Inkxaso yobuGcisa kunye-neNkonzo yoThengiso
Izixhobo zoshishino azikho nje i-hardware. -inkxaso yexesha elide ibalulekile ngokulinganayo.
Umthengisi othembekileyo kufuneka akwazi uku:
- Yenza uvavanyo lwe-weld yesampula ngaphambi kokuthenga.
- Nika iisetingi ezicetyiswayo zeparameter ngokusekelwe kwizinto zakho.
- Nikeza ngoqeqesho lwabaqhubi kunye nenkxaso yeendawo ezisecaleni.
Kumashishini afana neemoto kunye nokuveliswa kwamandla amatsha, inkxaso yenkqubo eqhubekayo ihlala ixabiseke ngakumbi kuneenkcazo zezixhobo zokuqala.
Indlela yokuphucula i-Welding Parameters kwiZiphumo eziZinzile
Ukukhetha umatshini ochanekileyo linyathelo lokuqala kuphela. Ukuseta iparameter efanelekileyo kubalulekile kumgangatho we-weld ongaguqukiyo.
1. Ibhalansi yangoku, ixesha kunye namandla
Umgangatho we-weld uxhomekeke kwizinto ezintathu eziphambili: i-welding current, ixesha le-weld, kunye ne-electrode force. Ezi parameters kufuneka zisebenze kunye.
Ukuba ubona isitshizi esigqithisileyo, umsinga unokuba phezulu kakhulu okanye amandla aphantsi kakhulu. Ukuba amandla e-weld akonelanga, ukwandisa ixesha langoku okanye elongezelelweyo le-weld kunokunceda. Yenza uhlengahlengiso ngokuthe ngcembe kunotshintsho olukhulu ukuze ufumane ibhalansi engcono.
2. Lawula iNdawo eChaphazeleke bubushushu
Ukufumana iindawo ezichanekileyo, ukusebenzisa i-current ephezulu kunye nexesha elifutshane le-weld kunokunceda ukwenza i-weld nugget ngokukhawuleza ngelixa unciphisa ukusasazeka kobushushu. Oku kunciphisa umngcipheko wokugqwetheka okanye ukuguga komphezulu.
3. Gcina i-Electrodes rhoqo
Imeko ye-Electrode inempembelelo ngqo kumgangatho we-weld. Nditsho neyona nto iphakathi umatshini wokuwelda indawo ayinakuvelisa iiwelds ezingaguqukiyo ukuba iingcebiso ze-electrode zinxitywe okanye zixutywe nge-oxidized.
Ukunxiba ingcebiso rhoqo yenye yezona ndlela zilula kwaye zinexabiso-ezona ndlela zisebenzayo zokugcina umgangatho wemveliso ozinzile.
Kutheni ukhetha oomatshini bokuwelda be-HAIFEI?
I-HAIFEI igxile ekudingeni izicelo zokuwelda, ukuquka uqhagamshelo lwebhasi yobhedu, ukudityaniswa kwesinyithi esingafaniyo, kunye-nolwakhiwo lwamandla aphezulu.
Yethuoomatshini bokuwelda amabala aphakathizakhiwe ngetekhnoloji yoguqulo oluzinzileyo kunye{0}}neziguquli zokusebenza eziphezulu. Sikwabonelela ngovavanyo lwesampulu kunye nenkxaso yenkqubo yokuqinisekisa ukuba izixhobo zihambelana nesicelo sakho ngaphambi kokuphunyezwa ngokupheleleyo.
Ukuba uceba ukuphuculwa kwezixhobo, ukuthelekisa iziphumo ezichanekileyo ze-welding kunye nedatha yokusetyenziswa kwamandla kuya kukunceda wenze isigqibo esisebenzayo. Ukukhetha umatshini wokuwelda ophakathi nendawo yeyona nto iphambili ekuphuculeni umgangatho we weld kunye{1}}nexesha elide lemveliso esebenzayo.
