Multiple tool

A multiple tool for a punching device (1), comprising

• a) a driving mechanism (10), which can be displaced in a punching direction (9), the driving mechanism (10) having
• i) a driving head (13) for driving the driving mechanism (10) by means of the punching device (1), and
• ii) a driving body (16) connected to the driving head (13),
• b) a punching tool magazine (11), which is connected to the driving mechanism (10), the punching tool magazine (11) having
• i) a guide body (27), and
• ii) a plurality of punching tools (50) guided in the guide body (27),
• wherein the punching tools (50) in each case have an effective punching length for punching a workpiece (8) to be machined, and
• wherein the driving body (16), during punching use, in each case cooperates with one of the punching tools (50) to drive the one of the punching tools, and
• c) a mechanical punching length testing mechanism to test the effective punching length of the punching tools (50),
• wherein the punching length testing mechanism has at least one test spring element (40), which is disposed and configured such that a displacement of the punching tool (50) in the punching direction (9) when the punching tool (50) is tested leads to an actuation of the test spring element (40), and the test spring element (40) in the actuated state exerts a restoring force on the punching tool (50) being tested,
• wherein the test spring element (40) can be manually actuated by finger pressure,
• wherein the test spring element (40) has a spring rate, which is between 0.1 N/mm and 5 N/mm,
• wherein the test spring element (40) can be compressed in the punching direction (9) relative to a base element (32), which is provided on the guide body (27) and has at least one through-opening (36) for the punching tools (50), and
• wherein the finger pressure directed onto the base element (32) is exertable by a machine operator or tester via a test opening (55) on a punching tool head (51) of the punching tool (50) to be tested so that the punching tool (50) to be tested is axially displaced in the punching direction (9).
