Hat Bending (Counter-Type)
SPCC : 0.6 - 1.6mm SUS : 0.6 - 1.2mm
This tool creates square-shape (like Hat shape ) groove by one operation. Four (4) bends can be made all in one operation material and no turning is required. Product flatness and dimensional accuracy is well satisfied.

Necessary Tonnage Calculation
SPCC | Tonnage /m above x1.0 x product length(mm)÷1000 |
---|---|
SUS | Tonnage /m above x1.5 x product length(mm)÷1000 |
AL | Tonnage /m above x0.6 x product length(mm)÷1000 |
Cautions
Marring
Marring appears on the punch hold-down area and die side surface.
Check Machine Capacity
Be sure that required tonnage gained by equation above does not exceed the machine capacity.
Product Accuracy
Product height accuracy becomes ± 0.2mm. Product width A accuracy -0, +0.2mm. R1 radius becomes t (material thickness) and R2 becomes t x 2.
