BREAK PRESS TONNAGE

Tons required per foot to bend mild steel having max. 60.000 PSI tensile strength.

Tonnage table part #1

All of the bending pressures are nominal and represent average conditions. These values are dependent upon the radii if the dies, the yield strength of the material, the temper of the material, the direction of the rolling stains etc.

PUNCHES AND DIES

85° - 90° Forming Punches & Dies

85° punch and die combinations are used for air bending techniques.  To produce sharp, close-tolerance bends in light gauges, 90° punch and die combinations must be specified.

30° Forming Punches & Dies

30° dies are used for forming acute angle bends in 22 gauge through to 3/16".

Gooseneck Punches & Dies

These punches are used for forming right angle bends, channels, or other special bends where a straight 90° punch would interfere.  GN #7, 8 and 9 punches are cut back further beyond the centerline for a greater flange.

4 - Way Dies

Block sizes and openings on 4 - way does can be made to customer specifications, including more than four openings. All openings are 85° unless otherwise specified.

Offset Dies

Offset dies are sold in sets.  General purpose offset dies form two 90° bends in one stroke.
