FUNCTIONS
This machine is a press brake whose upper beam is hydraulically
lowered. The UP and DOWN foot pedals are pressed to move up and
down the upper beam. The punches are mounted in the punch
holders attached to the upper beam, and the dies and die holders are
mounted on the lower beam. The worksheet is laid over the dies,
supported by hand, and bent by lowering the upper beam onto the dies.
The bend angle of the worksheet depends on the clearance between
the dies and punches. The upper beam is moved up and down by the
main cylinders installed on the right and left sides. The auxiliary
cylinders are installed at the center of the lower beam to prevent a long
worksheet from being bent with a greater angle toward the center (or to
keep the clearance between the upper and lower beams uniform in the
longitudinal direction). The main cylinders can be controlled
independently to tilt the upper beam. This tilting function allows the
difference in the bend angle between the right and left sides of the
worksheet to be compensated for and the worksheet to be offset bent
(or bent off the center of the machine). The worksheet can also be
pushed against the stoppers of the backgauge to determine its bend
position. The machine can be operated from the NC control box.

Coordinate system of axes
The machine is controlled by the D1, D2, L1, L2, Y1, Y2 and Z axes.
D1 axis: Axis along which the left main cylinder of the upper beam
moves up and down
D2 axis: Axis along which the right main cylinder of the upper beam
moves up and down
L1 axis: Axis along which the backgauge moves back and forth on
the left ball screw
L2 axis: Axis along which the backgauge moves back and forth on
the right ball screw
Y1 axis: Axis along which the left backgauge moves left and right
Y2 axis: Axis along which the right backgauge moves left and right
Z axis: Axis along which the backgauge moves up and down

NOTICE
● When the backgauge is to be used close to the punches, take care so that
the stopper fingers do not interfere with the punches that move as the
worksheet is bent.
Worksheet overhang
The backgauge can be used as a sheet support.
Load capacity: 20 kg.
Gently place the worksheet on the backgauge so that no shock is
applied to the backgauge.
NOTICE
● When the weight of the worksheet exceeds its load capacity, the backgauge
may drop down. In such a case, the worksheet may spring upward or slip
downward as shown below. Be sure that the worksheet weight does not
exceed the backgauge load capacity.
