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/m

Thickness   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.
