Bending tool, in particular an upper tool or a punch, and a change operation method

摘要

The invention relates to a bending tool (1) comprising a tool body (2) with an upper (3) and an opposite lower end region (4), wherein in the upper end region (3) a fastening extension (5) and in the lower end region (4) Working tip (6) is formed. In the tool body (2) a tool identification mark (11) is arranged, and in the attachment extension (5), at least one side surface (8) and this not outstanding, a communication interface (9) is arranged, which via a connecting line (10 ) is connected to the tool identification mark (11). In the tool body (2) an electronic unit (12) is arranged. On the attachment extension (5) is arranged opposite the tool body (2) electrically isolated voltage supply contact (14) which is connected to a power supply module (15) of the electronic unit (12). In the connecting line (10), a switch (16) is further arranged, wherein in a first switching position, the tool identification (11) with the communication interface (9), and in a second switching position of the switch (16), the electronic unit (12) is connected to the communication interface (9).
