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.

Tool Spec.

Mat. SPCC, SUS, AL
Thickness  mm 0.6 - 1.6(SUS less than 1.2)
Hight (H)  mm (t x 5) - 15
Width (A)     mm (t x 4) - 30

Required Tonnage

Required bending tonnage /per m(SPCC) unit kN/m
Radius mm 5 10 15 20 30
Thickness mm 0.6 360 350 350 340 340
0.8 490 470 470 470 460
1 610 590 580 580 580
1.2 - 700 690 680 680
1.6 - 950 930 930 920

* 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.
