Uzifumana njani iimpumelelo zokuSebenza ngeCapacitive Discharge Spot Welder: Ukusuka kwiHemispherical ukuya kwiSpecial Projections{0}}

Intshayelelo

Kwi-welding yeethebhu zebhetri kwizithuthi zamandla amatsha, ukusetyenziswa kweengqikelelo ze-hemispherical kwicapacitive discharge spot welderiinkqubo zonyuse amandla adibeneyo ngama-40%. Ngeli xesha, umenzi wokhuselo ufumene iqanda{2}}lokuwelda kwe-spatter yezinto ezibhityileyo{3}}zetitanium eludongeni kusetyenziswa uqikelelo olumilise ngokukodwa. Ezi mpumelelo zibonisa ukuba ijiyometri yentelekelelo ingaphezulu lee kunento yoyilo olulula{5}}idibanisa ulawulo lwangoku lwendawo, ibhalansi ye-thermodynamic, kunye nerheology yezinto. Njengowona mba uphambili wokumisela umgangatho we-weld, ubume bentelekelelo buchaphazela ngokuthe ngqo ukusebenza kogxininiso lwamandla (ngaphezulu kwe-92%) kunye nokuzinza kwe-nugget. Eli nqaku libonelela ngohlalutyo olucwangcisiweyo lweentlobo ezine zentelekelelo ezinkulu kunye nezicelo zabo zoshishino kwicapacitive discharge spot welderiteknoloji.

1. IMithetho-siseko eSisiseko: Indlela iMilo yeProjekthi ichaphazela ngayo uMgangatho weWeld

Uqikelelo ngaphakathicapacitive discharge spot welderIinkqubo zenza ukuba kukhululwe amandla abhekiselele. Uyilo lwabo kufuneka lufezekise iinjongo ezintathu:

• Ulawulo lwangoku lokuxinana: Lungiselela usasazo kwaye unqande iziphumo zomda (impazamo<±5%).
• Ummiselo woNgeniso lobushushu: Ibhalansi yokwenziwa kwe-nugget kunye nobushushu-indawo echaphazelekayo (HAZ).
• UkuSebenza ngoxinzelelo lokuSebenza: Qinisekisa ukuhanjiswa kwamandla afanayo (ukuguquguquka<±3%).

Iiparamitha zoyilo olungundoqo:

I-aerospace titanium sheet welding (0.3mm ubukhulu)

Ukufakelwa kwezonyango okudityanisiweyo kwezinto ezifanayo

2.3 Uqikelelo oluthe tyaba

• Amagqabantshintshi oyilo:

Umphezulu othe tyaba<0.01mm

Ukusangqa koMphetho R=0.05–0.2mm

• Ixabiso elinguNdoqo:

Unikezelo loxinzelelo olugqwesileyo (<±1.5% fluctuation)

Ilungele izinto zobunzima obuphezulu-(HRC Inkulu kuno okanye ilingana no 40)

50% ukuphucuka kwisithuba -sokugqiba umphezulu weweld
