Bayanin Labari:
I. The thermodynamic tushe ka'idar da hannu a cikin zafi shrin inji: Aikace-aikace na ka'idar fadada thermal da ƙanƙancewa a cikin kayan aiki clamping
1. Key Data a Kimiyyar Materials:
Alloy thermal expansion coefficient na mariƙin:
Karfe zafi shrinkable kayan aiki rike: α ≈ 11 × 10⁻⁶ / ℃ (yana faɗaɗa da 0.33mm lokacin da zafin jiki ya tashi da 300℃)
Hard alloy kayan aiki: α ≈ 5 × 10⁻⁶ / ℃
Tsarin dacewa da tsangwama:
ΔD=D0 . α. ΔT
Misali: Hannun kayan aiki na φ10mm yana mai zafi zuwa 300 ℃ → Diamita na ramin yana faɗaɗa da 0.033mm → Bayan sanyaya
Cimma madaidaicin yarda na 0.01 - 0.03mm
2.Comparison of Abvantages of Heat Thrinking Machine Technology:
| Hanyar matsawa | Diamita Runout | Watsawar Karfi | Mitar aikace-aikace |
| Mai Riƙe Fit | ≤3 | ≥ 100 | 50,000+ |
| Mai Rike Kayan Aikin Ruwa | ≤5 | 400-600 | 35,000 |
| ER Spring tattara | ≤10 | 100-200 | 25,000 |
