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.

Tool Spec.

Mat.	SPCC, SUS, AL
Thickness        mm	0.6 - 2.3
Angle	60 - 90
Bead Hight (H)  mm	t x 2 - 15
Bead Width (V)   mm	t x 4 - 30

Required Tonnage

Required bending tonnage /per m(SPCC) unit kN/m

Bead Width (V) mm		5	10	15	20	30
Thickness mm	0.6	200	100	70	50	30
	0.8	350	170	120	90	60
	1	540	270	180	140	90
	1.2	-	390	230	200	130
	1.6	-	700	460	350	230
	2	-	-	730	540	360
	2.3	-	-	960	720	480

*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
