Curling Double-Deck Type
SPCC : 0.6 - 2.3mm SUS : 0.6 - 1.5mm
The two operations of U-bend and curling are made using one tool. No tool change is required and set-up time is reduced for mass-production. (Height-adjustment is required for each process.)

Tool Spec.
Mat. | SPCC, SUS, AL |
Thickness mm | 0.6 - 2.3(SUS less than 1.5) |
Inner Radius (D) mm | t x 4 - 1.5 |
Required Tonnage
Required bending tonnage /per m(SPCC) unit kN/mThickness mm | 0.6 | 0.8 | 1 | 1.2 | 1.6 | 2 | 2.3 |
---|---|---|---|---|---|---|---|
Required Ton kN/m | 200 | 260 | 330 | 400 | 530 | 660 | 760 |
* Required Tonnage kN/m=330×Thickness * 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
Both processes of 1st and 2nd have marring as shown below.
Check Machine Capacity
Be sure that required tonnage gained by equation above does not exceed the machine capacity.
Product Accuracy
Product inner diameter accuracy φD ±0.2mm.
Open Hight
Distance piece has to be removed when this type tool is used on open-height 300mm.
