Abstract: A press brake assembly including a crane system and press brake machine for processing a workpiece. The crane system having a workpiece handling mechanism configured to pick and store the workpiece. The crane system allows the crane to move along a plane via longitudinal and lateral rails. The crane also includes multiple swivel points to allow mobility to handle workpieces efficiently. The control system of the press brake machine may control the crane, allowing a single control system to control the press brake assembly.

Abstract: A press brake for bending a workpiece that includes a movable ram and a support beam. The press brake includes a backgauge that has an arm with a plurality of fingers for grasping the workpiece. The arm is mounted to an arm support that is mounted on a carriage that is mounted on a backgauge support frame. The arm is configured to swing relative to the arm support in a plane perpendicular to the carriage from a position projecting away from one side of the carriage to a position projecting away from the other side of the carriage. The carriage is configured to rotate 180 degrees so that opposite sides of the workpiece may be positioned under the ram to thereby allow for bending operations to be performed on opposite sides of the workpiece without removing the workpiece from the backgauge.

Abstract: A press brake for bending a workpiece. The press brake a movable ram and a support beam. A punch is connected to the ram, and a die is connected to the support beam. The punch and the die are separated by a gap and the workpiece is placed in the gap in order to be bent. The ram is configured to be driven towards the support beam to thereby close the gap between the punch and the die. The die includes a pair of die members extending in a longitudinal direction separated by a recess having a width in a lateral direction perpendicular to the longitudinal direction. The width of the recess is adjustable by moving the die members. The die members are configured to move vertically to disengage from the support beam to thereby allow for lateral movement of the die members to adjust the width of the recess.

Abstract: A press brake machine for bending metal having an angle measurement system. The angle measurement system having at least one angle measurement device configured to measure the bend characteristics of the workpiece. The angle measurement device including an actuator, a position sensor, and a contact segment. The actuator of the measurement device is configured to abut the contact segment to the workpiece. The position sensor is configured to send data to a press brake controller to adjust the bending of the workpiece depending on the reading of the angle measurement device.

Abstract: A method of bending a sheet of metal using a press brake includes pivoting die holders during the bending operation so bends can be made in opposite directions without having to turn over or flip over the sheet of metal. In the method a first die holder is driven downward toward a second die to thereby create a bend in the metal sheet when the first and second dies come together. The first die holder and the first die are then retracted away from a second die holder and the second die. The die holders are moved, preferably rotated, to a second position in which the first die holder is located over the second die holder. Then the second die holder is driven downward toward the first die to thereby create a second bend in the metal sheet when the first and second dies come together.
