Bending tool, in particular upper tool or bending punch, and drive change method

摘要

The present invention relates to a bending tool (1) having a tool body (2) with an upper end region (3) and a lower end region (4) opposite to the upper end region (3). A fixed protrusion (5) is formed in the part region (3), and a working point (6) is formed in the lower end region (4). A tool identification mark (11) is arranged in the tool body (2) and does not stick out to and beyond at least one side (8) in the fixed projection (5). The communication interface (9) is arranged, and the communication interface is connected to the tool identification mark (11) via the connecting wire (10). An electronics unit (12) is arranged in the tool body (2). A voltage supply contact (14) that is electrically insulated from the tool body (2) is arranged on the fixed protrusion (5), and the voltage supply contact is a voltage supply module (15) of the electronics unit (12). ). Further, a changeover switch (16) is arranged in the connecting wire (10). In this case, the tool identification mark (11) is connected to the communication interface (9) at the first changeover position, and the changeover switch (16). In the second switching position, the electronics unit (12) is connected to the communication interface (9). [Selection] Figure 1
