R Beading

SPCC : 0.6 - 2.3mm SUS : 0.6 - 2.0mm

This tool creates half-shaped radius beading by one operation. Tool structure becomes quite simple at a lower cost. There is no material turn-over required.

*Required Tonnage (kN/m) = {(90 x t2) / R} x 10
* 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 H dimension accuracy ± 0.2mm R1 on right side drawing becomes 2x thickness t.
