Iinkuni zokuwelda ze-ultrasonic zicutshungulwa kwisithando sonyango lobushushu esikhethekileyo se-vacuum.

Ii-mold ze-ultrasonic kunye nee-mold zentsimbi ye-ultrasonic zizinto eziphambili kwizixhobo ze-ultrasonic welding, kwaye ukuchaneka komphezulu wazo, ubulukhuni, kunye nokumelana nokuguguleka kugqiba ngokuthe ngqo umgangatho we-welding. Kwinkqubo yokwenziwa kwe-mold yentsimbi, unyango lobushushu be-vacuum kwisithando esikhethekileyo linyathelo elibalulekileyo ekuphuculeni ukusebenza kwesikhunta sentsimbi. I-Shenzhen Chengguan Intelligent Ultrasonic Co., Ltd. (ebizwa ngokuba yi "Chengguan Intelligent"), njengomthengisi oqeqeshiweyo wezixhobo zokuwelda ze-ultrasonic kunye neesikhunta eTshayina, iphumelele impumelelo ephindwe kabini ekuchanekeni nasekusebenzeni kweesikhunta zentsimbi ngokusebenzisa iinkqubo zesithando somlilo esenziwe ngokwezifiso.

I. Iimfuno eziphambili ze-Ultrasonic Steel Molds zoNyango lobushushu

Iimold zentsimbi ze-ultrasonic zihlala zenziwe intsimbi yokubumba (efana ne-SKD11, DC53) kwaye kufuneka zinyamezele ukungcangcazela, ukungqubana, kunye nempembelelo ephezulu, ngoko ke zinemfuneko engqongqo yonyango lobushushu.

1. Ubulukhuni obuphezulu : Ubunzima bomphezulu kufuneka bufikelele kwi-HRC58~62 ukuqinisekisa ukumelana nokuguguleka;
2. Ukuguquguquka okuphantsi : Ukuchaneka kwesikhunta sentsimbi kufuneka kulawulwe ngaphakathi kwe-0.01mm, kwaye ukuguquguquka emva konyango lobushushu kufuneka kube
3. Ayina-oxidation : Umphezulu wesikhunta sentsimbi kufuneka ugcinwe uthambile ukuze kuthintelwe ukuchaphazela ukuchaneka ngexesha lokusila okulandelayo.

Unyango lobushushu lwendabuko lunokukhokelela kwi-oxidation kunye nokuguquguquka okugqithisileyo kweenkuni zentsimbi, ngelixa iChengguan Intelligent isebenzisa isithando somlilo sonyango lobushushu se-vacuum esenzelwe wena , ehambelana ngokugqibeleleyo nezi mfuno.

II. Uqwalaselo olwenziwe ngokwezifiso lweChengguan Intelligent Vacuum Heat Treatment Furnace

Ukuze kuhlangatyezwane nobukhulu obuncinci kunye neempawu ezichanekileyo ze-ultrasonic steel molds, iChengguan Intelligent, ngokubambisana nabavelisi bezixhobo, yenzelwe wena isithando sobushushu esincinci esicokisekileyo se-vacuum ngolu qwalaselo lulandelayo oluphambili:

• Iiparamitha zesithando somlilo : ubungakanani obusebenzayo φ200×300mm, ifanelekile ekucutshungulweni kwebhetshi yeenkuni zentsimbi ezili-10~15 ngebhetshi nganye;
• Inkqubo yokufunxa umoya : Iyunithi yepompo yemolekyuli isetyenziselwa ukugcina i-vacuum ezinzileyo ye-5×10⁻³Pa, ngaloo ndlela ithintela i-oxidation kumphezulu we-mold yentsimbi;
• Inkqubo yokulawula ubushushu : Iindawo ezi-4 ezizimeleyo zokulawula ubushushu, ukufana kobushushu ±1℃, ukuqinisekisa ubulukhuni obuhlala buhleli kuzo zonke iindawo zesikhunta sentsimbi;
• Inkqubo yokupholisa : ukucima igesi ngokwezigaba (okokuqala ukupholisa ngokukhawuleza nge-1MPa nitrogen, uze ukupholisa kancinci nge-0.3MPa) ukunciphisa ukuguquguquka koxinzelelo lobushushu.

III. Ukuhamba kweNkqubo yeSithando soTyando loBushushu seNsimbi yeUltrasonic (iChengguan Intelligent Practice)

I-Chengguan Intelligent idibanisa unyango lobushushu be-vacuum kuyo yonke inkqubo yokwenziwa kwe-mold yentsimbi. Amanyathelo athile ngala alandelayo:

1.Xa itshaja isithando somlilo, i-mold yentsimbi ilungiswa ngomatshini we-CNC, kwaye ioyile yomphezulu kunye nee-burrs ziyacocwa. Emva koko iyabotshelelwa kusetyenziswa isixhobo sokubotshelelwa se-graphite

yenziwe ngokwezifiso yiChengguan Intelligent (ukuthintela ukuba isikhunta sentsimbi singanamatheli kwisixhobo sokubopha) kwaye ibekwe ngokulinganayo kwitreyi yokutshaja yesithando somlilo.

2.ukucoca nge-vacuum kunye nokufudumeza , uze uvale ucango lwesithando somlilo, qala ngokususa umoya uye kwi-vacuum ephantsi (10⁻¹Pa) ukuze ususe umoya, uze uphakamise i-vacuum ukuya kwinqanaba ekujoliswe kulo (5×10⁻³Pa); fudumeza ukuya kwi-850℃

ngesantya se-5℃/min uze ubambe imizuzu engama-20 (ukuze uhlangabezane neemfuno ze-austenitization zezinto ze-SKD11).

3.Ukucima i-vacuum Kwenziwa ngokupholisa ngokukhawuleza isikhunta sentsimbi ngegesi ye-nitrogen ecocekileyo kakhulu eyi-1MPa, kunciphisa ubushushu ukusuka kwi-850℃ ukuya kwi-200℃ (izinga lokupholisa liyi-15℃/s). Emva koko,

ubushushu butshintshelwa kwi-0.3MPa yegesi yenitrogen ukuze kuphole kancinci ukuya kubushushu begumbi ukuze kuthintelwe uxinzelelo.

4.ukufudumala kwe-vacuum kunye xa icima, isikhunta sentsimbi sibuyiselwa kwisithando esikhethekileyo, sifudunyezwe sibe ngama-200℃, size sigcinwe imizuzu engama-60 ukuze kupheliswe uxinzelelo lwangaphakathi kunye nokuzinzisa.

ubukhulu be-mold yentsimbi (i-Chengguan Intelligent ilawula ukuguquguquka kwe-mold yentsimbi ukuya kwi-0.003mm ngale nkqubo).

5.isithando somlilo , umphezulu wesinyithi ogqunyiweyo ukhanya kwaye awuna-oxidation. Emva kokuphumelela uvavanyo lobunzima (HRC60±1) kunye novavanyo lokuchaneka (i-3D scanner), ingena kwinkqubo elandelayo yokupholisha.

6.IV. Ixabiso lobuchwephesha loNyango lobushushu beVacuum kwiiFurnaces ezizinikeleyo (uPhando lweTyala leChengguan Intelligent)

Ngokusebenzisa inkqubo yesithando somlilo esenziwe ngokwezifiso, isikhunta sesinyithi se-ultrasonic sikaChengguan Intelligent sifezekise oku kulandelayo:

• Ubomi obude : Ubomi obuqhelekileyo benkonzo yeenkuni zentsimbi bunyusiwe ukusuka kwimijikelo yokuwelda engama-50,000 kwinkqubo yendabuko ukuya kwimijikelo engama-120,000;
• Ukuchaneka okuzinzileyo : Ukuphindaphinda kwesikhunta sentsimbi kugcinwa ngaphakathi kwe-0.01mm, kwaye isivuno seemveliso ezidityanisiweyo siphucukile ukuya kwi-99.5%;
• Ukunciphisa iindleko : Ukuncipha kweenkqubo zokugaya nokuhlaziya ezilandelayo kuye kwehlisa iindleko zokuvelisa isikhunta sentsimbi esinye nge-15%.

Njengeshishini eliqhutywa bubuchwepheshe kwicandelo lokuwelda nge-ultrasonic, iChengguan Intelligent idibanise nzulu ubuchwepheshe besithando sonyango lobushushu be-vacuum

ukuphuhlisa i-mold yentsimbi ngokusebenzisa uyilo oludibeneyo lwe-"izixhobo + i-mold + inkqubo", ebonelela ngezisombululo ze-welding ze-ultrasonic ezithembekileyo ngakumbi kumashishini afana ne-elektroniki, amalaphu, kunye neemoto.
