Kwimizi-mveliso yale mihla, iProjection Welding (PW), eyahluka-hlukeneyo esebenzayo ye-Resistance Welding, isetyenziswa ngokubanzi ukudibanisa izinto zemoto, izixhobo zombane zasekhaya, kunye neemveliso zombane, ngakumbi ukuwelda amandongomane, izitudi, okanye{0}}uqikelelo olwakhiwe ngaphambili kwishiti lentsimbi. Impumelelo yeprojekithi yewelding imiselwa ngokunzulu bubungakanani kunye nokumila kweProjekthi.
Eli nqaku libonelela ngohlalutyo olunzulu-lweemfuno ezingundoqo ezine zengqikelelo yemilinganiselo kwi-spotwelding applications, inikezela ngesikhokelo esisebenzayo sokuphumeza{1}}umgangatho wengqikelelo welds ophakamileyo ngokusekelwe kwidatha egunyazisiweyo yoshishino kunye nemigangatho.
1. "I-Golden Ratio" yoBonelelo lweProjekthi ukuya kuButyebi beMathiriyeli
Ubude boqikelelo yiparameter ebalulekileyo yokuqinisekisa ukuxinana kobushushu kunye nokwakheka kwe-weld nugget. Ayiloxabiso elimiselweyo kodwa lihambelana ngokusondeleyo nobukhulu bezinto ezidityanisiweyo.
Imfuneko engundoqo: Ibhalansi eDynamic yoMphakamo
Amava kunye nemigangatho yoshishino ibonisa ukuba ubude bentelekelelo kufuneka bugcine ibhalansi eguqukayo kunye nobukhulu bezinto ezipheleleyo:
- Umgaqo kabhontsi: Ubude bentelekelelo ngokuqhelekileyo bunconywa ukuba bube phakathi kwe-1.2 kunye ne-1.5 ngokuphindaphinda ubukhulu bephepha elincinci.
- Injongo: Ukuqinisekisa ukuba iprojekti iwa ngokufanelekileyo phantsi kwe-electrode force, igxininise i-current and heat kwi-interface yoqhagamshelwano phakathi kweprojekthi kunye neshidi, ngaloo ndlela yenza i-weld nugget ezinzileyo.
| Isiphumo soBubude obungafanelekanga boQekelelo | Inkqubo yeMpembelelo | Isiphumo seWelding |
| Ubude obunganelanga | Indawo yoqhagamshelwano inkulu kakhulu, ukuxinana kwangoku kuyahlakazwa | Ubushushu obungonelanga, ubungakanani obuncinci be-nugget, ukungonelanga kwamandla adibeneyo (i-weld ebandayo / i-fusion eyaneleyo) |
| Ubude obugqithisileyo | Uqikelelo luwa ngokukhawuleza kakhulu, ukugxothwa kwesinyithi esiqatha (i-spatter) | Ithanda ukutshisa{0}iphepha elicekethekileyo, ukuncamathela kwe-electrode, inkangeleko ye weld embi |
Ireferensi yoMgangatho ogunyazisiweyo
Kwezona zicelo zixhaphakileyo zokuwelding{0}i-weld nuts kunye ne-studs{1}}imigangatho yamazwe ngamazwe efana ne-ISO 5821 ichaza iimfuno ezineenkcukacha zokumila kunye nobukhulu boqikelelo ukuqinisekisa ukuthembeka kunye nokungaguquguquki ngexesha lenkqubo yokuwelda. Abavelisi badla ngokuyila kwaye bavelise uqikelelo olwakhiwe kwangaphambili{4} ngokwale migangatho.
2. I-"Art of Matching" I-Projection Diameter kunye ne-Electrode Force
Ububanzi bentekelelo bumisela ngokuthe ngqo indawo yokuqala yoqhagamshelwano, nto leyo echaphazela ukuxinana kwangoku kunye namandla afunekayo e-electrode.
Imfuno enguNdoqo: Ulawulo oluchanekileyo loXinano lwangoku
Umgaqo wentelekelelo ye-welding kukuvelisa ubushushu ngokusebenzisa ukuchasana okuphezulu koqhagamshelwano kwindawo yokubonisa. I-diameter enkulu ithetha indawo enkulu yoqhagamshelwano kunye noxinano oluphantsi lwangoku. Ukufikelela kwiqondo lokushisa elinyibilikayo, amandla aphezulu akhoyo okanye amakhulu afunekayo ukukhawulezisa ukuwa kweprojekthi.
- Ukunyanzeliswa kokuhambelana: Idayamitha enkulu yokubonisa ifuna amandla amakhulu e-electrode (uxinzelelo). Ngokomzekelo, xa udibanisa ubukhulu obuthile be-carbon steel, i-5 mm ye-diameter projection inokufuna amandla e-electrode ukuya kwi-73,500 Newtons (malunga . 7.5 neetoni ze-metric) ukuqinisekisa ukuwa okufanayo phantsi kweempembelelo zangoku.
- Amandla angonelanga: Inokubangela ukuba uqikelelo lunyibilike kodwa lungawi ngokupheleleyo phantsi kwangoku, olukhokelela ekubunjweni kwe-nugget okungaphelelanga kunye namandla angonelanga.
- Amandla Amandla: Iyakwazi ukuthambisa ingqikelelo phambi kosetyenziso lwangoku, ukunciphisa ukuxhathisa koqhagamshelwano, okukhokelela ekwenziweni kobushushu okwaneleyo, okanye konakalise umphezulu womsebenzi.
Umahluko okhoyo phakathi kweProjekthi kunye ne-Spot Welding
Kubalulekile ukuqaphela ukuba okukhoyo okufunekayo kwindawo nganye yeweld kwiprojection welding ngokuqhelekileyo ingaphantsi kunoko kufuneka kwindawo enye. Oku kungenxa yokuba ingqikelelo yewelding iqwalasela ekhoyo kwintelekelelo{1}}eyakhiwe ngaphambili, inyusa ingxinano yangoku kwaye ivumela ubushushu obunyibilikayo bufikelelwe ngomsinga osezantsi.
3. Ijiyometri kunye ne "Balance of Multi{1}}Spot Welding"
Ijometri yoqikelelo (umzekelo, i-hemispherical, conical, okanye i-annular) ibalulekile kugxininiso lwangoku kunye nebhalansi ye-multi{2}}yelding ye-spot.
IMfuneko enguNdoqo: uQhoqo kunye nokuTshaniswa koBume
- Ijometri eqhelekileyo: Ukusebenzisa ijometri eqhelekileyo (efana ne-hemispherical okanye i-conical) yandisa ugxininiso lwangoku, iqinisekisa ubushushu obuveliswa ngokufanayo kumbindi wentelekelelo.
- Umngeni we-Multi-Spot Welding: Kwizicelo apho uqikelelo oluninzi ludityaniswe ngaxeshanye (umzekelo, ezininzi{3}}iprojection weld nuts), owona mceli mngeni mkhulu kukuqinisekisa ukuba zonke iingqikelelo zifikelela kwiqondo lobushushu lokunyibilika kwaye ziwohloke ngokufanayo ngaxeshanye. Ukuba nayiphi na ingqikelelo enye iwa kwangaphambi kwexesha, inokubangela ukushukuma kwangoku, okukhokelela ekudibaneni okunganeleyo kwezinye iindawo.
Izisombululo zangoku:{0}}IziXhobo eziQonkqileyo kunye nezivaliweyo{1}}Ulawulo lweLoop
- Ukujongana nemiceli mngeni ye{0}}yokuwelda iindawo ezininzi, iiwelder zale mihla kufuneka zibonise:
Ukuqina okuPhezulu kunye nokuLandela- phezulu: Umshiseli kufuneka abe nobungqongqo okwaneleyo ukuze amelane noxinzelelo oluphezulu kwaye abe nesakhono sokuLandela{1}} esisemagqabini, ukuqinisekisa ukuba i-electrode inokulandelela ngokukhawuleza intelekelelo ngexesha lokuwa kwayo, ngokuqhubekayo ifaka uxinzelelo ukunqanda ukugxothwa.
- Ezivaliweyo-Iinkqubo zokuLawula iLuphu: Izixhobo zala maxesha zifakelwe{1}}iisistim ezivaliweyo zolawulo oluluphu ezibeka esweni iisignali ezifana nombane, okwangoku, kunye nokususwa kwe-electrode ngexesha lokwenyani{2}}. Ezi nkqubo zilungelelanisa iiparamitha ze-welding ukuqinisekisa iqondo eliphezulu lokuhambelana phakathi kwamandla, okwangoku, kunye nexesha, ukufezekisa ukudibanisa okuhambelanayo kwiiprojekthi ezininzi.
4. Ugcino lwe-Electrode kunye -neTerm Dimensional Consistency
Nokuba uyilo loqikelelo olugqibeleleyo, ukunxitywa kwe-electrode kunokubeka esichengeni ngokuthe ngqo ukuguquguquka kwe-dimensional ye-weld yentelekelelo, echaphazela umgangatho we-weld.
Imfuno enguNdoqo: Ukugcina uMphezulu woQhagamshelwano lwe-Electrode eZinzile
Ukunxiba i-Impact: Ii-electrodes ezigugileyo zitshintsha indawo yokudibanisa kunye ne-workpiece, ekhokelela ekunciphiseni koxinano lwangoku, olufuna umsinga ophezulu ukufezekisa ukushisa okufanayo.
- Ukugqoka rhoqo: Ukuhlolwa kwe-electrode rhoqo kunye neenkqubo zokugqoka kufuneka ziphunyezwe ukuze kugcinwe ukugqitywa komphezulu kunye nejometri ye-electrode tip. Oku kuqinisekisa ukuba ingxinano yangoku ihlala ingatshintshi kuyo yonke i-weld.
- Inkqubo yokupholisa: Inkqubo yokupholisa ibalulekile kubomi be-electrode. Ukuhamba kwamanzi okupholisa okwaneleyo (umzekelo, isantya sokuhamba kwe- $\\ge 60 $ iilitha/ngomzuzu) kususa ngokufanelekileyo ubushushu be-welding, ukunciphisa ukuthambisa kunye nokuguga kwezinto ze-electrode, ngaloo ndlela ukwandisa ubomi be-electrode kunye nokuqinisekisa ukuhambelana kwemilinganiselo ye-projection.
IziKhokelo zokuPhunyezwa kunye noQinisekiso loMgangatho
Ukufikelela kwiziphumo ezizezona zilungileyo zokuwelda, abavelisi kufuneka babambelele kwezi zikhokelo zilandelayo kunye nemilinganiselo yokuqinisekisa umgangatho:
| Ukuphunyezwa kweSikhokelo | Umgangatho woQinisekiso loMgangatho |
| Ukuseka iDatabase yeParameter | Yenza i-database eqinisekisiweyo yemilinganiselo kunye neeparitha zezixhobo ezithile kunye neentlobo zentelekelelo. |
| Ugcino olucwangcisiweyo | Ukuphumeza uhlolo oluqhubekayo lwe-electrode yokunxiba rhoqo kunye nokusebenza kwenkqubo yokupholisa. |
| Uqeqesho lwabaSebenzisi | Qinisekisa ukuba abaqhubi bayayiqonda imigaqo yoyilo loqikelelo, ingqiqo yohlengahlengiso lweparamitha, kunye neemfuno zolawulo lomgangatho. |
Ukuqukumbela
Imfuno yobukhulu boqikelelo kwiukuwelda indawousetyenziso yinkqubo entsonkothileyo ebandakanya ijometri, isayensi yezinto eziphathekayo, kunye nemigaqo yombane. Ifuna ukuba abavelisi bangathembeli kuphela kuyilo lwentelekelelo oluchanekileyo kodwa nakwizixhobo eziphakamileyo-ezingqongqo, iinkqubo ezikrelekrele ezivaliweyo-zezixokelelwano zolawulo lwelophu, kunye neenkqubo zogcino olucwangcisiweyo.
Ngokulawula ngokuchanekileyo ubude bentelekelelo, ububanzi, ijometri, kunye nokugcinwa kwe-electrode, iinkampani zinokuwuphucula kakhulu umgangatho, uzinzo, kunye nokusebenza kakuhle kwemveliso ye-welding ye-welding, ukuqinisekisa uqhagamshelo oluthembekileyo noluzinzileyo kwizicelo ezahlukeneyo zokwenziwa.
