BENDING TOOL, IN PARTICULAR AN UPPER TOOL OR A BENDING PUNCH, AND A METHOD FOR CHANGING THE OPERATING MODE

摘要

The invention relates to a bending tool (1), comprising a tool body (2) having an upper (3) and an opposite lower end region (4), wherein a fastening extension (5) is formed in the upper end region (3) and a working tip (6) is formed in the lower end region (4). A tool identification tag (11) is arranged in the tool body (2), and a communication interface (9) is arranged in the fastening extension (5) on at least one side surface (8), but does not protrude, said communication interface being connected with the tool identification tag (11) via a connecting line (10). An electronics unit (12) is arranged in the tool body (2). A voltage supply contact (14), which is electrically insulated with respect to the tool body (2), is arranged on the fastening extension (5), said voltage supply contact being connected to a voltage supply module (15) of the electronics unit (12). Furthermore, a change-over switch (16) is arranged in the connecting line (10), wherein, in a first switching position, the tool identification tag (11) is connected with the communication interface (9) and, in a second switching position of the change-over switch (16), the electronics unit (12) is connected with the communication interface (9).
