Abstract: The invention refers to the field of bending presses for plate sheets and more precisely it refers to a process and a device for detecting the bending angle in real time when the press punch operates on the sheet placed above the matrix die. The process provides for the generation of at least two flows of compressed air in at least two matrix die points that are totally or partially covered by the plate sheet. The pressure variation during the bending step is measured and such variation is compared with sample pressure values. The device provides for a compressed air system with a pressure reducer that supplies four orifices and a servo-controlled device that performs a compensation.

Abstract: A support medium is capable of being read by a numerical control system of a bending machine. The support medium stores program instructions for searching, in a memory region storing at least one group of data, each containing bending conditions, a bend angle and at least one penetration depth, whether input data including a desired bend angle and bending conditions are stored in the memory region, in a same group of data. The support medium sends a signal to the bending machine so that the bending machine executes a bending according to the penetration depth included in the same group of data.

Abstract: A computer-based control for a press brake of the type having a ram for bending a sheet metal workpiece to a desired bend angle. The control incorporates a teach mode which collects ram force and position data during the bending of one or more test workpieces and calculates from the force and position data parameters representative of the ram reversal position necessary to produce the desired bend angle. The control also incorporates a bend mode for bending a production workpiece to the desired bend angle wherein force and position data is collected during the bending of the production workpiece and is used in conjunction with the parameters calculated during the bending of the test workpieces during the teach mode to calculate the exact position of ram reversal necessary to produce the desired bend angle in the production workpiece. The control also incorporates correction of the position of ram reversal to account for ram overshoot during the bend mode.

Abstract: The device employs a number of detectors (1) mounted at the level of the upper surface of the die (2) and a numerical control system (5). The purpose of the detectors is to signal to the numerical control the moment that the part b of the sheet begins to rise. The device allows the automatic determination of the thickness of the sheet in the area where the bend is to be located, during the course of the forming operation. The thickness of the sheet is then used by a numerical control system to correct the travel of the tool, without interrupting the forming cycle, in such a way as to obtain with high precision the required bend angle.

Abstract: This invention relates to a numerical control method for a press brake or the like. The back stopper is positioned by driving the motor. In the case where it is impossible to bend a working piece because the back stopper interferes with the working piece, the back stopper is retracted with the lid of a retraction instruction and a back stopper position data. Before the back stopper is retracted, the working piece is held by the punch. The program data of each process can be confirmed by using suitable display units.

Abstract: A control system for a press brake having a frame, a bed, a ram, and a hydraulic system for reciprocating the ram toward and away from the bed. Top and bottom limit switches, actuated by the ram, are provided for establishing the maximum ascent and descent of the ram, and a speed control limit switch, disposed between the top and bottom limit switches, defined a work stroke wherein the ram in descending is slowed as it comes into contact with a work piece for greater accuracy and operator safety. To prevent set-up adjustments to the bottom limit switch from affecting the length of the work stroke, a novel mechanical coupling arrangement is provided whereby the position of the speed control switch is automatically shifted to compensate for changes in the position of the switch. Means are also provided for coupling the top limit switch to the speed control limit switch to achieve a constant overall ram operating cycle.

Abstract: A structure to apply flexing to an object to test resilience to being bent has a first portion and a second portion. The structure includes a base, a rotating member, a pressing plate, and an adjusting assembly. The base defines first and second receiving grooves, and the second receiving groove receives the first portion. The rotating member on the base is partially received in the first receiving groove. An abutting surface of the rotating member is recessed to form a third receiving groove which receives the second portion. The pressing plate on the base presses against the first portion. The adjusting assembly controls the rotating member to rotate towards the base about a desired angle, thereby causing the second portion to be bent with respect to the first portion.
