R-Bend Urethane Type

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

This urethane die is suitable for larger R bending. No marring appears on the component surface and helps prevent multiple-breakage. Also this tool has versatility and cost-performance because only punch is replaced for required radius.

* Bending angle 90°
* 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

No marring appears.

Check Machine Capacity

Be sure that required tonnage gained by equation above does not exceed the machine capacity.

Selection judgment

When urethane is selected product Inner Radius >30.

Product Accuracy

Product R size accuracy R±5
