Abstract: An electronic angle measuring device for a bending machine for measuring the bending angle between the legs (4) of a sheet (5) using a sensor element (7) is described, which supplies angle-equivalent signals in a contactless manner to a signal processing unit (9), which has a microprocessor and a memory unit and is connected to a digital display (10). To provide simple measuring conditions, it is proposed that the sensor element (7), the signal processing unit (9), and the display (10) form an angle measuring device (6) which is fastenable on the upper tool (1) of the bending machine and is usable as a handheld encoder, and which has a motion sensor (11), which is connected to the signal processing unit (9) and detects the lowering and/or raising movement of the upper tool (1), for triggering the measuring procedure

Abstract: A press brake includes a first guide rail on one side, a second guide rail on another side, an ATC device and a first measurement portion movable on the first guide rail, and a second measurement portion movable on the second guide rail. The first and second measurement portions measure a bent angle of a workpiece. The second guide rail is different from the first guide rail in their cross-sectional shapes. The first measurement portion includes a main unit having a sensor, and a first coupling portion coupling the main unit with the first guide rail. The second measurement portion includes the main unit, and a second coupling portion different from the first coupling portion coupling the main unit with the second guide rail. The ATC device and the measurement portions can be made coexistent and the main units of the measurement portions can be made identical to each other.

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: During the process of bending a workpiece, actual load exerted on the workpiece and displacement are sampled and the bending stress to displacement relationship is obtained from the sampling data and data on the actual thickness of the workpiece. From the bending stress to displacement relationship, a material characteristic value (e.g., yield stress) which indicates the condition of the material of the workpiece is obtained. Then, a bending angle correction amount is obtained from the material characteristic value, using a data table concerning the material characteristic value to bending angle relationship. From the bending angle correction amount thus obtained, a correction depth amount is obtained. The correction depth amount is added to a preset reference depth amount to obtain a final depth amount according to which bending is performed.
