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： 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： The device comprises a base (12), a mobile support (14), a contact member (16), a lever (34) which comprises a blocking arm (38) pivotally mounted around an axis (36). The device comprises retention means (40, 42) capable of opposing the pivoting of the lever. The device also comprises a reaction member (48A) fixed with respect to the base (12) and capable of cooperating with a reaction zone of the blocking arm (38) by defining a reaction surface inclined with respect to the translation direction X of the support on the base. The pivoting of the lever allowed by the release of the retention means allows the displacement of the contact member.

摘要： A work processing apparatus upwardly turns a wrist of a vertical articulated robot to retract a hand that is holding a work to a position where the hand and work do not interfere with a press brake. In this state, an engaging projection arranged at a front end of an upper arm or at the wrist is inserted into an engaging hole of a lower die of the press brake and the vertical articulated robot is operated to move the lower die along a groove of a die holder.

摘要： A metal sheet-receiving system for receiving parts and feeding a metal sheet-folding machine, particularly a folding press comprising at least one manipulator for seizing and moving metal sheet parts with a gripper head fitted with gripping means; an electronic controlling device for controlling the movements of the manipulator; as well as a measuring system for determining the position of the metal sheet parts. The measuring system is formed by an optoelectronic measuring device, particularly an image acquisition means, and a transillumination platform.
