5, the input of the mold parameters and the like can be performed easily and quickly at the time of cartridge replacement, and the setup time is shortened. That is, by inputting the cartridge information K in advance at a position distant from the press body 1, the setup time in the press body 1 can be saved. For example, when the press machine body 1 is in operation, even if the control means 4 which is the NC device is not touched, it is possible to input the mold parameters simultaneously with the setup station such as the cartridge magazine 2 or the mold exchange outside the machine. Can be performed. In the illustrated embodiment, mold parameters and the like can be written in the cartridge information storage means 15 of the cartridge 6 by the cartridge information rewriting means 17 provided in the setup station 2aa of the cartridge magazine 2. Further, since the mold parameters and the history are managed by the cartridge information storage means 15 composed of a memory chip or the like, re-input is facilitated and no mistake is made. Further, since not the individual molds 7 and 8 but a plurality of molds 7 and 8 are collectively managed, the use efficiency of the cartridge information storage means 15 including a memory chip or the like is increased, and the cost can be reduced.

In the above embodiment, the cartridge information storage means 15 is fixedly attached to the cartridge 6, but the cartridge information storage means 15 may be detachably attached to the cartridge 6 as shown in FIG.

Floppy disks, punch cards, etc. can be used.
As described above, when the cartridge information storage means 15 is detachable, measures such as storing the cartridge information storage means 15 in a place different from the press machine body 1 when carrying the cartridge 6 into the press machine body 1 can be performed. Further, the cartridge information storage means 15 can be easily detached from the cartridge 6 and managed when necessary, so that maintenance of the cartridge information storage means 15 and reading and writing of data become easy. Further, since the cartridge information storage means 15 does not need to be exposed to the impact of the punch, oil, slag, etc., an inexpensive storage medium such as a magnetic card can be used as the cartridge information storage means 15. If the management of the mold history is unnecessary, a cheaper punch card or the like can be used as the cartridge information storage means 15. When the cartridge information storage means 15 is a card or the like, for example, as shown in FIG.

In the above embodiment, the cartridge 6
Is applied to a cartridge-type punch press of a type in which the cartridge 6A is directly moved in the press body 1, but as shown in FIG. The present invention can be applied.

It may be provided in storage means of a management computer (not shown). In the integrated storage means 30, each cartridge specifying information K such as a cartridge number is stored.
The cartridge information K which is mold information for one cartridge 6 is stored in association with 1, K2,.
Further, mold information about a mold not mounted on the cartridge 6 is also stored.

In this configuration, the cartridge 6 is provided with a storage means 15A for storing cartridge identification information such as a cartridge number, and the cartridge information input means 16A reads the cartridge identification information, and reads the cartridge identification information. It is assumed that the cartridge information K for one corresponding cartridge in the integrated storage means 30 is input to the cartridge information storage unit 18 from the specific information. Other configurations are the same as those of the above embodiment. In the case of this configuration, the cartridge 6 only needs to be provided with the cartridge identification information. Therefore, the storage means 15A provided in the cartridge 6 has a small amount of information and requires only a simple storage medium.

Further, by changing the example of FIG. 10, the cartridge information input means 16A inputs the read cartridge specifying information to the control means 4, and the control means 4 uses the input cartridge specifying information, The mold information of the mold station of the corresponding cartridge in the integrated storage means 30 may be directly read into the currently used mold information storage means 19 by a tool command of the machining program.
