Triangle Beading
SPCC : 0.6 - 2.3mm SUS : 0.6 - 2.0mm
This tool creates triangle-shape beading by one operation. Tool structure becomes quite simple at a lower cost. There is no material turn-over required.

*Required Tonnage (kN/m) = {(272xt2) / V} 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 accuracy ±0.2mm
R1 becomes 1/2 of thickness in the right side.
And R2 becomes 2 x thickness
