ABSTRACT:
The present invention provides a punch press which enables cartridges to be easily replaced so that the replacement of the cartridges allows the use of a large number of tools, which enables tools in the cartridges to be quickly indexed, and which allows the accuracy of punching to be easily improved. Cartridges3, 4are used which hold tools1, 2, respectively. Cartridge holders6, 7are provided which hold the cartridges3, 4, respectively, that are supported by a punch frame5and located at a press position P. A ram10is provided above the cartridge means holders6, 7. The cartridge holders6, 7have cartridge clamps14, 15, respectively, removably holding the corresponding cartridges3, 4. The cartridge holders6, 7have cartridge rotating mechanisms16, 17, respectively, that rotate the held cartridges3, 4in order to index any of the tools1, 2. The cartridge holders6, 7fix the cartridges3, 4during punching so that the cartridges cannot be moved in a vertical direction.
