Ƙarfe kayan aikin bugawa Design: Key Principles
Kyakkyawan ƙirar mutuƙar yana hana 80% na gazawar ƙasa. Mahimman ka'idodin:
1. Yankewa
Kula da 5-8% na kauri na hannun jari a kowane gefe don ɓarna da huda cikin ƙaramin ƙarfe. Tsaftacewa mai tsauri (3-5%) yana inganta ingancin gefe amma yana gajarta rayuwar mutu kuma yana ƙara ton. Tsare-tsare (8-12%) yana tsawaita rayuwar mutu amma yana haifar da bursu masu girma.
2. Die Saka Geometry
- Ƙaƙwalwar kusurwa akan naushi: 1-3° a kowane gefe yana rage ƙwanƙwasa ƙarfi da tonnage spikes da 30-50%.
- Mutuwar tsayin ƙasa: 3-5mm don kayan da ke ƙarƙashin 2mm lokacin farin ciki; 5-8mm don 2-6mm stock. A ƙasa waɗannan dabi'un, mutuƙar fatattaka yana haɓaka.
- Zana mutu radius: Mafi ƙarancin kauri 4× don radius hanci. A ƙasan wannan, an kusan tabbatar da tsagewar kayan cikin ayyukan zane mai zurfi.
3. Layout Strip (Progressive Dies)
- Mafi qarancin gada nisa tsakanin sassa: 1.2× stock kauri.
- Mai ɗaukar hoto nisa: ƙaramin 10mm don amincin injina.
- Diamita na Pilot: mafi ƙarancin 3mm, an sanya shi cikin farar 0.5 na tashar kafa mai mahimmanci.
4. Jagoranci da Daidaitawa
- Yi amfani da ginshiƙan jagora masu ɗaukar ƙwallo (ba bushings a fili) don mutu tare da sharewa ƙasa da 5% kowane gefe.
- Diamita fil ɗin jagora yakamata ya zama aƙalla 10% na tsayin mutuwa don tsayayya da jujjuyawar gefe ƙarƙashin lodin tsakiya.
