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.
