China imvi kuponyedwa chitsulozipolopolo nkhungu kuponyera mankhwalandi OEM mwambo ndi CNC Machining misonkhano. Zosiyanasiyana zitsulo kalasi zilipo.
Kupanga zida zachitsulo ndi zitsulo monga momwe makasitomala amawonera ndi gawo lathu lofunikira kwambiri la ntchito zopangira zolondola koma osati ntchito zathu zokha. Kwenikweni, timapereka ntchito zopangira zitsulo zoyimitsidwa kwathunthu ndi mautumiki osiyanasiyana owonjezera kuphatikiza kupanga, makina a CNC mwatsatanetsatane, chithandizo cha kutentha, kumaliza pamwamba, kusonkhanitsa, kulongedza, kutumiza ... etc.
Asanapange nkhungu ndi pachimake, mchenga wokutira waphimbidwa ndi filimu yolimba ya utomoni pamwamba pa mchenga. Thechipolopolo nkhungu kuponyeraapangidwa kukhala mchenga wokutidwa pogwiritsa ntchito thermoplastic phenolic resin plus latent curring agent (monga urotropine) ndi mafuta odzola (monga calcium stearate) kudzera munjira inayake yopaka. Mchenga wokutidwa ukatenthedwa, utomoni womwe umakutidwa pamwamba pa mchengawo umasungunuka. Pansi pa zochita za gulu la methylene lomwe limavunda ndi Maltropine, utomoni wosungunuka umasintha kuchokera ku mzere wozungulira kupita ku thupi losasunthika kotero kuti mchenga wophimbidwa umalimba ndikupangidwa. Kuphatikiza pa mchenga wowuma wouma, palinso mchenga wonyowa komanso wokutidwa ndi viscous.
▶ Kuponya mchenga kuli ndi izi
1) Ili ndi magwiridwe antchito oyenera. Ikhoza kukwaniritsa zofunikira pa mchenga wa chipolopolo champhamvu kwambiri, mchenga wa bokosi lamphamvu lapakati, ndi mchenga wa alloy wopanda mphamvu zochepa.
2) Kusungunuka kwabwino kwambiri, kuumbika bwino kwa pachimake cha mchenga ndi ndondomeko yomveka bwino, yomwe imatha kupanga mchenga wovuta kwambiri, monga mchenga wa jekete lamadzi monga mitu ya silinda ndi matupi a makina.
3) Ubwino wapakatikati pa mchenga ndi wabwino, wophatikizika komanso wosamasuka. Ngakhale zokutira zocheperako kapena zosagwiritsidwa ntchito, zopanga zapamwamba zitha kupezeka. The dimensional kulondola kwa castings akhoza kufika CT7-CT8, ndi pamwamba roughness Ra akhoza kufika 6.3-12.5μm.
4) Kuwonongeka kwabwino, komwe kumathandizira kuyeretsa ndikuwongolera magwiridwe antchito
5) Mchenga wapakati siwosavuta kuyamwa chinyezi, ndipo mphamvu yosungiramo nthawi yayitali sivuta kuchepa, yomwe imathandizira kusungirako, kuyendetsa ndi kugwiritsa ntchito.
▶ Kapangidwe ka nkhungu zamchenga (core) popanga zipolopolo:
1. Njira yayikulu yopangira nkhungu yamchenga (pachimake) ndi: kutembenuza kapena kupukusa mchenga → kutumphuka → kutulutsa mchenga → kuumitsa → pachimake ( nkhungu) ndi zina zotero.
1) Pindulani kapena phulitsa mchenga. Ndiko kuti, mchenga wokutidwa umatsanuliridwa pa nkhungu ya chipolopolo kapena kuwombedwa mu bokosi lapakati kuti apange chipolopolo kapena chipolopolo pakati.
2) Kukhazikika. Kuchuluka kwa chipolopolo cha chipolopolo kumayendetsedwa ndi kusintha kutentha kwa kutentha ndi nthawi yogwira.
3) Kutuluka kwa mchenga. Pendekerani nkhungu ndi bokosi lapakati kuti mchenga wosakanizidwa ugwe kuchokera pachigoba chotenthedwa, ndipo sonkhanitsani kuti muugwiritsenso ntchito. Kuti zikhale zosavuta kuchotsa mchenga wosasungunuka wosasungunuka, ngati kuli kofunikira, njira yamakina yogwedeza mmbuyo ndi mtsogolo ingatengedwe.
4) Kuwumitsa. M'malo otentha, kuti makulidwe a chipolopolocho akhale ofanana, agwirizane ndi pamwamba pa chipolopolo chamoto mkati mwa nthawi yowonjezereka.
5) Tengani pachimake. Chotsani mawonekedwe a chipolopolo cholimba ndi chipolopolo chapakati pa nkhungu ndi bokosi lapakati.
▶ Zopangira Zopangira Zipolopolo:
• Cast Carbon Steel: Low Carbon Steel, Medium Carbon Steel ndi High Carbon Steel kuchokera ku AISI 1020 mpaka AISI 1060.
• Cast Steel Alloys: 20CrMnTi, 20SiMn, 30SiMn, 30CrMo, 35CrMo, 35SiMn, 35CrMnSi, 40Mn, 40Cr, 42Cr, 42CrMo... etc pa pempho.
• Kutaya Zitsulo Zosapanga dzimbiri: AISI 304, AISI 304L, AISI 316, AISI 316L ndi kalasi ina yachitsulo chosapanga dzimbiri.
• Ma Aluminiyamu Otayirapo.
• Mkuwa & Mkuwa.
• Zida Zina ndi Miyezo pakupempha
▶ Mphamvu Zoponya Zipolopolo:
• Kukula Kwambiri: 1,000 mm × 800 mm × 500 mm
• Kulemera kwake: 0,5 kg - 100 kg
• Mphamvu Zapachaka: matani 2,000
