Ma ultrasonic welding molds amakonzedwa mu uvuni wapadera woyeretsera kutentha wa vacuum.

Zinyalala za ultrasonic ndi zinyalala zachitsulo za ultrasonic ndi zigawo zazikulu za zida zowotcherera za ultrasonic, ndipo kulondola kwa pamwamba pake, kuuma kwake, ndi kukana kusweka kwake zimatsimikiza mwachindunji mtundu wa kuwotcherera. Mu njira yopangira zinyalala zachitsulo, chithandizo cha kutentha kwa vacuum mu uvuni wapadera ndi gawo lofunika kwambiri pakukonza magwiridwe antchito a nkhungu yachitsulo. Shenzhen Chengguan Intelligent Ultrasonic Co., Ltd. (yomwe tsopano ikutchedwa "Chengguan Intelligent"), monga kampani yogulitsa zida zowotcherera ndi nkhungu za ultrasonic ku China, yapeza chitukuko chambiri pa kulondola ndi moyo wa nkhungu zachitsulo kudzera mu njira zosinthira kutentha kwa vacuum zomwe zakonzedwa mwamakonda.

I. Zofunikira Zazikulu za Ma Ultrasonic Steel Molds pa Kutentha

Zitsulo zopangidwa ndi chitsulo cha ultrasonic nthawi zambiri zimapangidwa ndi chitsulo cha nkhungu (monga SKD11, DC53) ndipo amafunika kupirira kugwedezeka kwamphamvu, kukangana, ndi kugwedezeka, motero ali ndi zofunikira kwambiri pakuchiza kutentha.

1. Kuuma kwambiri : Kulimba kwa pamwamba kuyenera kufika pa HRC58 ~ 62 kuti zitsimikizire kuti palibe kuwonongeka;
2. Kusintha kochepa : Kulondola kwa nkhungu yachitsulo kuyenera kulamulidwa mkati mwa 0.01mm, ndipo kusintha kwa kutentha kuyenera kukhala
3. Yopanda okosijeni : Pamwamba pa nkhungu yachitsulocho payenera kukhala posalala kuti pasakhudze kulondola kwake panthawi yopera.

Chithandizo cha kutentha chachikhalidwe chingayambitse kukhuthala kwa okosijeni ndi kusintha kwambiri kwa nkhungu zachitsulo, pomwe Chengguan Intelligent imagwiritsa ntchito ng'anjo yotenthetsera ya vacuum yokonzedwa mwamakonda , zomwe zikugwirizana bwino ndi zosowa izi.

II. Kusintha Kopangidwa Mwamakonda kwa Ng'anjo Yotenthetsera Kutentha ya Chengguan Intelligent Vacuum

Kuti zigwirizane ndi kukula kochepa komanso mawonekedwe olondola kwambiri a nkhungu zachitsulo za ultrasonic, Chengguan Intelligent, mogwirizana ndi opanga zida, adasintha mawonekedwe awo. ng'anjo yaying'ono yoyeretsera kutentha kwa vacuum ndi makonzedwe otsatirawa apakati:

• Magawo a ng'anjo : kukula kogwira ntchito φ200×300mm, koyenera kukonzedwa ndi gulu la nkhungu zachitsulo 10~15 pa gulu lililonse;
• Dongosolo losambitsa mpweya : Chipangizo chopopera cha molekyulu chimagwiritsidwa ntchito kusunga vacuum yokhazikika ya 5×10⁻³Pa, motero kupewa okosijeni pamwamba pa nkhungu yachitsulo;
• Dongosolo lowongolera kutentha : Madera 4 odziyimira pawokha owongolera kutentha, kufanana kwa kutentha ± 1℃, kuonetsetsa kuti kuuma kokhazikika m'malo onse a nkhungu yachitsulo;
• Dongosolo loziziritsira : kuzimitsa mpweya pang'onopang'ono (choyamba kuziziritsa mofulumira ndi nayitrogeni ya 1MPa, kenako kuziziritsa pang'onopang'ono ndi 0.3MPa) kuti muchepetse kusintha kwa kutentha.

III. Kuyenda kwa Njira ya Ultrasonic Steel Mold Vacuum Heat Treatment Furnace (Chengguan Intelligent Practice)

Chengguan Intelligent imaphatikiza chithandizo cha kutentha kwa vacuum mu njira yonse yopangira nkhungu yachitsulo. Masitepe enieni ndi awa:

1.Poyatsa uvuni, nkhungu yachitsulo imakonzedwa ndi makina a CNC, ndipo mafuta ndi ma burrs pamwamba pake amatsukidwa. Kenako imayikidwa ndi graphite clamping fixture

Zokonzedwa ndi Chengguan Intelligent (kuti nkhungu yachitsulo isamamatire ku chogwirira ntchito chomangirira) ndipo zokonzedwa mofanana pa thireyi yolipirira uvuni.

2.kutsuka ndi kutentha , ndikutseka chitseko cha ng'anjo, choyamba tulukani ku vacuum yochepa (10⁻¹Pa) kuti muchotse mpweya, kenako kwezani vacuum kufika pamlingo womwe mukufuna (5×10⁻³Pa); kutentha kufika pa 850℃

pa liwiro la 5℃/mphindi ndipo dikirani kwa mphindi 20 (kuti mukwaniritse zofunikira za SKD11 austenitization).

3.Kuzimitsa vacuum Zimachitidwa poziziritsa nkhungu yachitsulo mwachangu ndi mpweya wa nayitrogeni wa 1MPa woyeretsedwa kwambiri, kuchepetsa kutentha kuchokera pa 850℃ mpaka 200℃ (kuzizira kwa 15℃/s). Kenako,

kutentha kumasinthidwa kukhala mpweya wa nayitrogeni wa 0.3MPa kuti kuziziritsa pang'onopang'ono kufika kutentha kwa chipinda kuti tipewe kupsinjika kwambiri.

4.kutentha kwa vacuum ndi Pozimitsa, nkhungu yachitsulo imabwezeretsedwa mu uvuni wapadera, kutenthedwa kufika pa 200℃, ndikusungidwa kwa mphindi 60 kuti ichotse kupsinjika kwamkati ndikukhazikika.

kukula kwa nkhungu yachitsulo (Chengguan Intelligent imalamulira kusintha kwa nkhungu yachitsulo kufika mkati mwa 0.003mm kudzera mu njirayi).

5.ng'anjo , pamwamba pa nkhungu yachitsulo ndi yowala komanso yopanda okosijeni. Pambuyo popambana mayeso okhwima (HRC60±1) ndi mayeso olondola (3D scanner), imalowa mu ndondomeko yotsatira yopukuta.

6.IV. Kufunika kwa Ukadaulo wa Kutentha kwa Vacuum mu Uvuni Wodzipereka (Kafukufuku wa Chengguan Intelligent)

Kudzera mu njira yopangira ng'anjo yotenthetsera vacuum, nkhungu yachitsulo ya Chengguan Intelligent yakwaniritsa izi:

• Kutalika kwa nthawi yopuma : Nthawi yapakati yogwiritsira ntchito zinyalala zachitsulo yawonjezeka kuchoka pa nthawi 50,000 zowotcherera mu njira yachikhalidwe kufika pa nthawi 120,000;
• Kulondola kokhazikika : Kubwerezabwereza kwa nkhungu yachitsulo kumasungidwa mkati mwa 0.01mm, ndipo zokolola za zinthu zolumikizidwa zimawonjezeka kufika pa 99.5%;
• Kuchepetsa mtengo : Kuchepa kwa njira zopukutira ndi kukonzanso zinthu pambuyo pake kwachepetsa mtengo wopanga nkhungu imodzi yachitsulo ndi 15%.

Monga kampani yoyendetsedwa ndi ukadaulo pankhani yowotcherera ma ultrasonic, Chengguan Intelligent yaphatikiza kwambiri ukadaulo wothira kutentha kwa uvuni wa vacuum.

kupanga nkhungu zachitsulo kudzera mu kapangidwe kogwirizana ka "zipangizo + nkhungu + njira", kupereka njira zodalirika zowotcherera za ultrasonic m'mafakitale monga zamagetsi, nsalu, ndi magalimoto.
