Abstract: A press has an upper table carrying a punch and a lower table bearing a tool-carrier. A jack for compensating the deflection inherent in the bending process is fitted in the lower table. The bending device enables the bending angle obtained in the workpiece to be monitored continuously. The bending device includes a series of paired measuring rods, circular in section and longitudinally machined to provide a flat surface for the lower surface of the workpiece to rest on, associated with devices for measuring the rotational angle of the measuring rods, and a control device connected to the rotational angle measuring device, to a device for controlling the jacks that actuate the punch and to the actuating device of the jack for compensating the deflection. A very accurate and constant bending angle is obtained throughout the length of the workpiece. The bending process is automatic and continuous once the operator has fed in the required bending angle.

Abstract: An electronic adaptive control system for use with hydraulic press brakes to provide compensation for material spring back to accurately produce a desired bend angle in the work piece with a single ram stroke. Fixed input parameters associated with the press brake and material properties, together with ram position and force data are continuously input to a digital computer which calculates the precise point of punch penetration necessary to reverse ram movement in order to produce the desired bend angle in the work piece. By using in-process measurements, a significant savings in machine set-up-time can be achieved in order to produce an accurate bend angle in the work piece the first time and every time.

Abstract: A robot system for carrying out a bending process with respect to a workpiece held by a robot, in which an arc interpolation motion of the robot can be easily and precisely taught. A user coordinate system is set so as to specify a rotation axis of the bending motion in the bending process by inputting the position and/or angle of each axis of the robot to a teaching pendant by the operator. Next, in a teaching program of the robot, a process start position and an operation form are defined so as to add a bending process command, and a rotation angle of the bending process and an angular velocity of a command line about the rotation axis are designated. By virtue of this, an internal program for carrying out an arc interpolation motion by the robot is generated in a robot controlling part.

Abstract: Described is a procedure for bending a sheet of sheet metal on a panel bender machine wherein upon bending the sheet of metal sheet a first software (BE) for machine control transmits to a second software (VS) for management of a TV camera (17), positioned in alignment with the bending line, the data relating to the nominal bending angle, the bending length, the distance of the bent edge from the centre line of the panel bender and the thickness of the metal sheet. The second software (VS) acquires an image of the bent metal sheet, identifies the spatial position of the straight line corresponding to the bent edge of the sheet of sheet metal and then calculates its geometric coordinates in accordance with a preset referencing system, and supplies to the first software (BE) the value of the angle of the bend performed. The machine control is returned to the first software (BE), which calculates the difference between the angle of the bend actually performed and the angle of the nominal bend and then orders the start of a new bend corresponding to the angular difference, thereby obtaining a bend corresponding to the nominal bend.
