L-Bending Horizontal Type
SPCC : 0.5 - 1.2mm SUS : 0.5 - 1.0mm
L-bend on edge tooling keeps work horizontal. When sectionalized punch with Ear or hinged punch is used, 4(four) sides bend-up box bending can be produced.

Required Tonnage
Required bending tonnage /per m(SPCC) unit kN/mThickness mm | 0.5 | 0.6 | 0.8 | 1 | 1.2 |
---|---|---|---|---|---|
Required Ton kN/m | 73 | 100 | 123 | 152 | 179 |
* 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 as shown below. Polycarbonate shoulder piece reduces marring
Check Machine Capacity
Be sure that required tonnage gained by equation above does not exceed the machine capacity.
Thickness adjustment
Shoulder piece position must be adjusted by shims for each thickness.
Product Accuracy
Inner R becomes more than thickness t .
Backgauge Plate Width
Back-side thrust plate has gap of with 60mm for back-gauge plate guidance. Please specify the back-gauge plate width for more than 60mm when ordering.
