摘要： There is provided a press brake that can improve forming accuracy in partial bending. A press brake includes: a conveying mechanism that intermittently conveys a workpiece; a die including a pair of shoulder portions and a groove portion located between the pair of shoulder portions, the pair of shoulder portions being arranged away from each other in a conveying direction of the workpiece and supporting a rear surface of the workpiece; a backup plate that extends on the pair of shoulder portions, covers the groove portion, and is interposed between the die and the workpiece; and a punch that moves relative to the die so as to approach the die each time the conveying mechanism stops conveying the workpiece and presses the workpiece so as to bend the workpiece within an elastic deformation region of the backup plate.

摘要： The invention relates to a bending machine, in particular a press brake, having an upper beam and a lower beam. The upper beam is movable in a working direction of the bending machine in order to form a workpiece by bending along a bending line, which extends in a width direction of the bending machine. The bending machine includes a safety system having a first functional element and a further functional element for monitoring a safety area between both functional elements and between the upper beam and the lower beam. The safety system is arranged to follow the movement of the upper beam in the working direction. The first functional element and the further functional element are mechanically connected to one another via a flexible tractive force transmission means and an adjustment device for changing the position of the functional elements. The adjustment device includes a coupling section.

摘要： A method for processing a sheet metal part using a sheet metal working tool of a sheet metal working device, wherein the sheet metal working tool is a cutting blade or a press-brake jaw, wherein a sheet metal part to be processed is fixed on a cutting attachment or on a press-brake attachment by a blank holder, and the sheet metal working tool for processing the sheet metal part, proceeding from an initial position (A), carries out a lowering movement in the direction of the fixed sheet metal part. The sheet metal working tool in the process is lowered in such a way that a sheet metal contact region of the sheet metal working tool impacts the sheet metal part, and the sheet metal part is cut to size or bent by means of the sheet metal working tool.

摘要： A manipulator for components, in particular sheet metal parts, includes a base body mountable stationarily or movable along a guide arrangement, a first pivot arm pivotally coupled to the base body via a horizontal first pivot axis, a second pivot arm pivotally coupled to the first pivot arm via a horizontal second pivot axis and a third pivot arm pivotally coupled to the second pivot arm via a horizontal third pivot axis. A first axis of rotation extending radially to the third pivot axis is formed on the third pivot arm. A gripper support arm is rotatably coupled to the third pivot arm via the first axis of rotation and extends radially to the first axis of rotation. A gripping arrangement is rotatably coupled to the gripper support arm via a second axis of rotation spaced from the first axis of rotation. A bending installation includes the manipulator.

摘要： A system for shaping a workpiece, which may be in the form of a structural framing component, includes a tool with first and second indenting blades for indenting the workpiece as driven by a blade control apparatus. The workpiece is supported at the tool by one or more workpiece support modules that are each selectively and removably securable to the tool. A base plate is provided at the tool for removably securing the workpiece support modules to the tool without having to detach the tool from a platform of substructure. The workpiece support modules may therefore be quickly replaced to coordinate with workpieces of various size and shape.

摘要： A press brake assembly with a sheet follower with an actuation assembly that allows the sheet follower to follow a downwards bending workpiece. The sheet follow is adjacent to the press brake and is capable of following the workpiece throughout different bends without changing the position of the workpiece. The sheet follower includes a table and rotatable arms attached to the table. The actuation assembly of the sheet follower includes two blocks that is configured to move the rotatable arms that allow the table to follow the bending of the workpiece.

摘要： A method for forming large titanium parts includes forming bends into a titanium plate for form a bent part. The bent part is then roll-formed to form contours into the bent part. The surfaces of the contoured part are rough-machined, and the part is then secured to a bladed form fixture. The bladed form fixture comprises a plurality of header boards that secure the part to the fixture. The fixture part is placed in a thermal vacuum furnace and a stress-relieving operation is performed. The part is removed from the fixture and final machining takes place.

摘要： Systems and methods for bending a material to a target resultant bending parameter using a bend forming tool are disclosed. The systems and methods receive values for parameters of properties of the material and of a bending process to be performed by the bend forming tool, creating or retrieving a calibration curve relating input bending parameter and resultant bending parameter based on the values from a database of calibration curves, determining a first springback compensated input bending parameter based on the target resultant bending parameter using the calibration curve, inputting the first springback compensated input bending parameter to the bend forming tool, and in a first step of bending the material, bending the material to the first springback compensated input bending parameter by applying the bending process using the bend forming tool.
