Abstract
A method for straightening non-straight bar-shaped material (1) by determining a target plastic deformation (s_soll) at a forming position (12) of the bar-shaped material (1), moving a straightening hammer (8) with integrated measuring probe (7) to the forming position (12), a first forming stroke (h_1) of the straightening hammer (8) is carried out, an actual plastic deformation (s_ist) caused by the first forming stroke (h_1) is determined by means of the integrated measuring probe (7), a second forming stroke (h_2) is determined from the actual plastic deformation (s_ist) caused by the first forming stroke (h_1) and the target plastic deformation (s_soll).

A method for straightening non-straight bar-shaped material (1), comprising:
- providing a straightening machine comprising a traversing device including a straightening hammer (8) with an integrated measuring probe (7), and a control system including a memory configured to store a characteristic diagram (60) which displays a target plastic deformation (s_soll), an actual plastic deformation span for the bar-shaped material (1) for a plurality of forming strokes, an actual plastic deformation (s_ist), and a characteristic curve (61) for the bar-shaped material determined from the actual plastic deformation,
- determining the target plastic deformation, using the control system, at a forming position (12) of the bar-shaped material (1),
- controlling the straightening hammer to move to the forming position (12),
- controlling the straightening hammer, using the control system, to carry out a first forming stroke (h_1),
- controlling the measuring probe (7), using the control system, such that the measuring probe determines an actual plastic deformation (s_ist) caused by the first forming stroke (h_1) and feeds a measured value of the actual plastic deformation to the control system,
- generating the characteristic diagram (60), using the control system, after the first forming stroke (h_1),
- determining a second forming stroke (h_2), using the control system, from the actual plastic deformation (s_ist) caused by the first forming stroke (h_1), the target plastic deformation (s_soll), and the characteristic curve (61).
A straightening machine for non-straight, bar-shaped material (1) for carrying out a target plastic deformation (s_soll) at a forming position (12) of the bar-shaped material (1), comprising:
- a traversing device including a straightening hammer (8) with an integrated measuring probe (7),
- a control system, including a memory configured to store a characteristic diagram (60) which displays a target plastic deformation (s_soll), an actual plastic deformation span for the bar-shaped material for a plurality of forming strokes, an actual plastic deformation (s_ist), and a characteristic curve (61) for the bar-shaped material (1) determined from the actual plastic deformation,
- wherein the control system:
- determines the target plastic deformation at a forming position (12) of the bar-shaped material (1) a first forming stroke (h_1) from the target plastic deformation (s_soll),
- controls the straightening hammer (8) to move to the forming position (12),
- controls the straightening hammer (8) to carry out a first forming stroke (h_1),
- controls the integrated measuring probe (7) to measure the actual plastic deformation (s_ist) caused by the first forming stroke (h_1) and feed a measured value of the actual plastic deformation to the control system,
- generates the characteristic diagram (60) after the first forming stroke (h_1), and
- determines a second forming stroke (h_2) from the actual plastic deformation (s_ist) caused by the first forming stroke (h_1), the target plastic deformation (s_soll), and the characteristic curve (61).
