The Choice of Die Clamp

MODEL
CA: The template with the U cuts
CB: The template with no the U cuts
Choice Standard
  • Total clamping force which the machine needs (ΣF)=machine capacity (tons)x15~20%
  • The ratio of total clamping force is as follows:
  • Upper die (Σ F1)=ΣFx60%
    Lower die (Σ F2)=ΣFx40%
  • Each die clamping force (F)
    (according to the die clamp quantity (n) for each upper and lower die)
  • Upper clamp F=ΣF1 / n (tons)
    Lower clamp F=ΣF2 / n (tons)
    BOLT SIZE M16 M18 M20 M24 M30 M38
    Clamping force (ton) 1-3 2-4 4-6 6-10 8-15 15-20
