A bending machine with a work area image capture apparatus has a machine frame, a longitudinally extended, fixed machine table, and a longitudinally extended press beam moved by a drive relative to the frame and guided therein. The longitudinal expanse and the press beam movement direction define a working plane establishing a front working and manipulation space and a rear machine space. An image capture apparatus above the machine table in the machine space has a capture region oriented toward the machine space and is connected with a display configured to represent the captured image of the capture region. The capture apparatus is connected with the display by an image processing processor having a coordinate transformation module configured the captured image perspective. The coordinate transformation module is connected with a wireless position determination system configured to determine the machine operator position in the working and manipulation space.

A bending machine has a work area image capture apparatus. A longitudinal expanse and the movement direction of the press beam define a working plane, which establishes a front working and manipulation space and a rear machine space, which is distinguished from the former and, in particular, closed off. An image capture apparatus is disposed in the working and manipulation space above the machine table, in a center section of the longitudinal expanse of the press beam, which apparatus is connected with a display, which is configured for representation of the captured image of the capture region. The image capture apparatus is disposed in a press beam casing, and has two image capture devices, wherein each image capture device captures a partial section in the direction of the machine table.

A projector emits laser light, and an optical receiver includes a photodetector. When an upper table is lowered, a safety controller controls lowering of the upper table to stop, when it is determined that the optical receiver is in a light obstructing state in a period in which a condition is satisfied that a first distance between a tip of a punch and an upper end of a material is equal to or greater than a second distance between the tip of the punch and the photodetector, and controls the lowering to continue without stopping the lowering of the upper table even when it is determined that the optical receiver is in the light obstructing state in a period in which a condition is satisfied that the first distance is less than the second distance.

A sheet material bending system includes a tool changing apparatus that changes tools between a press brake and a tool stocker. The tool stocker is arranged behind the press brake. To change tools from the front and rear of the tool stocker, the front and rear of the tool stocker are opened. The tool changing apparatus has a pivot that is movable in front-rear, left-right, and up-down directions and is rotatable around an axis extending in the up-down direction. A front end of the pivot is provided with tool holding units to hold tools.

A tool or die component for a press brake apparatus includes a tool body having a coupling end adapted for coupling with a holder, and a working end adapted for operation on a workpiece. One or more magnetic elements can be adapted for selective engagement of the tool or die component within a punch press apparatus by magnetic coupling with the tool body, where the working end is configured for forming the workpiece by operation of the press brake apparatus. The magnetic coupling can be defined between the tool body and holder disposed adjacent the coupling end, or between the tool body and an adjacent tool or die component disposed along a side surface of the tool body, or both.

A die compatibility adaptor including a housing and a die cable extending outward from the housing and terminating at a die cable end engageable with a manufacturing die that includes a first proximity sensor configured to output a first proximity signal and a second proximity sensor configured to output a second proximity signal. The die compatibility adaptor further includes a direct cable receptacle communicatively coupled to the die cable, a duplicate cable receptacle, and one or more isolation relays positioned between and communicatively coupled to the duplicate cable receptacle and the die cable, the one or more isolation relays having a closed position and an open position. In the closed position, the duplicate cable receptacle is communicatively coupled to the die cable.

A pressing tool for plastically deforming a workpiece is described. The pressing tool includes a housing and an electric motor for actuating the pressing tool. The pressing tool also includes an instrument seat which is adapted to receive an interchangeable instrument head at the housing. The pressing tool also includes a mechanical safety element which is arranged in a manner that is movable from an open position, in which an instrument head may be inserted into the instrument seat, into a closed position, in which the instrument head is locked in the instrument seat. The pressing tool additionally includes a mechanical actuating element which may interact with the safety element in order to be able to cause the pressing tool to be enabled for a pressing process.
