Some bending methods
Technology News1)Suspended bending (also called three-point bending) The punch presses the workpiece into the die without pressing it against the die wall. When the punch core moves down, the edge of the workpiece bends upward and forms an included angle. The deeper the punch presses the workpiece into the die, the smaller the angle. At this…
