Trapezoidal Hat Bending (Counter-Type)

SPCC : 0.6 - 2.0mm SUS : 0.6 - 1.2mm

This tool creates trapezoid-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.

* Multiply x 1.5 to above figure for stainless steel, and x 0.6 to Al A5052

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
