    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: Controlling the bending of an overlapping edge portion of a metal shield of a cable core by supporting one side of an edge portion at a position along its feed path and applying pressure against the edge portion immediately downstream of and in a direction opposite to the support. Bending of the edge portion occurs immediately it has passed the support while the support dampers resiliency in the edge portion to prevent or lessen springback. Apparatus for bending is placed immediately upstream of the overlapping die and preferably includes means to vary the applied pressure. Hence, the desired orientation of the bent edge portion is obtainable by varying the pressure dependent upon the actual orientation as the overlapped shield leaves the die.

    Abstract: A method of straightening an elongated workpiece, in which the workpiece is supported at two spaced points and straightening forces are applied between these points by an automatically controlled hydraulic ram, governed by a programming system which causes the first stroke of the ram to defect the work beyond the desired final shape by a distance approximately equal to the calculated maximum elastic deformation, the load is then removed and the residual error sensed, and a further series of strokes applied at constant increments, the residual error being sensed between strokes and used to initiate a second series of stroke increments of smaller value until the residual error falls below a final preselected value at which acceptable straightness has been achieved.
