FUNCTIONS

This machine is a press brake whose lower beam is hydraulically raised by the linear
servo valves at the right and left sides. The UP and DOWN foot pedals are pressed to
move up and down the lower 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 raising the lower
beam onto the punches. The bend angle of the worksheet depends on the clearance
between the dies and punches. The lower 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 bend angle is finely adjusted by the right and left linear
servo valves, which can also be controlled independently to tilt the lower 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

Basically, the machine is controlled by the D1, D2, L1, L2, Y1, Y2 and Z axes and CC
value.

D1 axis: Axis along which the left main cylinder of the lower beam moves up and down

D2 axis: Axis along which the right main cylinder of the lower 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

CC value: Pressure of the auxiliary cylinders in the lower beam
