kuponya molondola

Njira ya Precision Casting imatanthawuza dzina lambiri la Njira Zoponyera zomwe zimagwiritsa ntchito zisankho zopanda zitsulo komanso zomwe mawonekedwe ake olondola ndi apamwamba kuposa momwe amapangira mchenga wamba, kuphatikiza Lost Wax Casting kapena Investment Casting, Plaster Mold Casting ndi Ceramics Mold Casting.

 

Kuponya kolondola pothira waxing

 

2-1 Mbali ndi ubwino

 

(1) Kutalika kwa malire a kuponyedwa ndi 700mm, ndipo kutalika kosavuta kumakhala kochepa kuposa 200mm. Kulemera kwakukulu kwa kuponyera kumakhala pafupifupi 100 kg, kawirikawiri osachepera 10 kg.

(2) The dimensional kulolerana kwa kuponyera ndi 20mm ± 0.13mm, 100mm ± 0.30mm, 200mm ± 0.43mm, ndi kulondola dimensional mbali yaing'ono n'kosavuta kufika mkati ± 0.10mm.Angle kulolerana ± 0.5~±2. madigiri, kuponyera osachepera makulidwe a 0.5 ~ 1.5mm.Pamwamba roughness wa kuponyera ndi za Rmax 4S~12S.

(3) kuponya zinthu pafupifupi popanda zoletsa, monga zotayidwa aloyi, magnesium aloyi, titaniyamu aloyi, aloyi mkuwa, mitundu yonse ya zitsulo, cobalt ndi faifi tambala zochokera kutentha kugonjetsedwa aloyi, zolimba zipangizo.

(4) kupanga mawonekedwe ovuta a workpiece, zabwino dimensional kulondola, zochepa kudula.

(5) sungani zinyalala zakuthupi, ndipo zitha kupangidwa mochulukira.

 

Dewax mwatsatanetsatane castings chimagwiritsidwa ntchito injini ndege, turbines gasi, turbines nthunzi, mbali ndege, injini kuyaka mkati, magalimoto, chakudya makina, makina osindikizira, mapepala kupanga makina, compressor, mavavu, mapampu, mamita, makina osokera, zida, makina malonda. , ndi mbali zina zamakina.

 

2-2 ndondomeko

 

Pali mitundu iwiri ikuluikulu ya njira zoponyera dewaxing: Solid Mold ndi Ceramic Shell Mould, yomalizayo kukhala kusinthidwa kwa zakale.

 

Njira yolimba ya nkhungu imaganizira za kuchepa kwa phula la nkhungu ya sera, kuwonjezereka kwa kutentha kwa nkhungu ndi kuchepa kwa chitsulo chosungunuka, ndikupanga nkhungu yomwe imakhala yofanana ndi kukula kwake komaliza. Sera yosungunuka imayikidwa muzitsulo nkhungu yopangidwa ndi chitsulo kapena gel osakaniza silika, nkhungu ya sera imachotsedwa, ndikuviikidwa mu slurry yopangidwa ndi kusakaniza zinthu zopangira ufa ndi zomangira. tinthu tating'onoting'ono tosakanikirana ndi zomangira, ndikuziwumitsa. Sera imatenthedwa kuti isungunuke ndikupanga nkhungu.Nkhunguyo idatenthedwa ndi kutentha kwambiri kuti itenthe phula yotsalira ndikuwonjezera mphamvu zake, kenako chitsulo. kusungunula anabayidwa.

 

Kupanga kwa ceramic chipolopolo nkhungu mpaka nkhungu sera ndi chimodzimodzi ndi nkhungu olimba, kupatula kuti pambuyo kuviika ndi mchenga drenching (kapena mchenga kuyandama), ❖ kuyanika ntchito si ikuchitika, koma mobwerezabwereza kangapo mpaka anakonzeratu. makulidwe a chipolopolo akupezeka.Njirayi imagwiritsidwa ntchito kwambiri pochotsa phula mwatsatanetsatane ogwiritsa ntchito pakali pano chifukwa ili ndi zabwino izi: kuyanika, kutentha, kusungunula sera, kutentha kwapamwamba kenako kuthira.

 

(1) Kukhazikika bwino kwa mawonekedwe

(2) Kuchepetsa kugwiritsa ntchito zida zomangira

(3) kulemera kopepuka, kosavuta kunyamula, kupanga ma castings akulu

(4) Njira yopangira zinthu imatha kukhala yodziwikiratu kuti ipulumutse anthu ogwira ntchito ndikuwongolera kuchuluka kwa kupanga

(5) Mtengo wotsika mtengo

(6) Chikombole cha ceramic chipolopolo ndi chochepa thupi, ndipo kuzizira kwa kuponyera pambuyo poponyedwa ndipamwamba komanso yunifolomu, kotero kuti makina ake ndi abwino.

 

(A) Chitsanzo Chachikulu

 

Maonekedwe a chitsanzo chachikulu ndi ofanana ndi mankhwala omaliza.Lingaliro liyenera kuperekedwa pakuchepera kwa sera, kukulitsa kutentha kwa nkhungu ndi kufota kwa chitsulo choponyera chitsulo.Mwachitsanzo, pamene kuzizira kwa nkhungu ya sera ndi 1.2%, kuchuluka kwa kutentha kwa nkhungu ndi 0.7%. , ndi kuzizira kwa shrinkage yachitsulo choponyera chitsulo ndi 1.7%, kukula kwa kukula kwa chitsanzo chachikulu ndi 2.2%.Zomwe zimagwiritsidwa ntchito kwambiri ndi aluminium alloy, copper alloy ndi chitsulo chosapanga dzimbiri.
