In this state, the punch and the die can be mounted on the punch holder and the die holder by the mold changer. Thus, the mold changer allows one-touch automatic exchange from the mold magazine to the punch holder and the die holder.

According to the fourth aspect of the present invention, the work can be laser-processed by providing the punch holder with the laser processing head. In addition, since each mold magazine is provided on the carriage frame on the opposite side, not on the work clamp side provided in the carriage, it is stored in each mold magazine when performing laser processing on the work. Since dust and the like generated during laser processing do not adhere to the punch and the die, it is not necessary to remove the dust from the punch and the die at the time of replacement, and dust can be prevented. Further, there is no dead zone due to the conventional mold storage shelves, and the space in one direction is minimized.

According to the fifth aspect of the present invention, the carriage is moved in the other direction while the workpiece to be machined is clamped by the work clamp, and the machining head holder on which the machining head is mounted is moved in one direction. ,
By positioning the desired position of the work at the position of the processing head and operating the processing head, plate work can be performed on the work.

A first processing head magazine for accommodating a plurality of processing heads at appropriate intervals in the other direction is provided on a work table provided on the other end side of the lower frame so as to be movable in the other direction, and the first processing head magazine is provided. Since the machining head is preset and stored in the magazine, when exchanging the machining head, the machining head holder is moved between the exchange position at which the machining head holder has moved to the first machining head magazine and the first machining head magazine. Since one processing head changer is provided, the processing head can be replaced by the first processing head changer. Thus, the time for replacing the processing head can be shortened as compared with the related art.

Since the first processing head magazine is provided on the work table provided on the other end of the lower frame without being provided on the moving carriage, the preset of the processing head can be changed even during the processing of the plate material. Since the first machining head magazine is not provided in the carriage,
It is not affected by the inertia of the machining head on the moving axis of the carriage.

According to the sixth aspect of the present invention, when it is desired to replace the processing head provided on the first processing head magazine with another processing head, the second processing head changer is used to automatically change the processing head. The replacement can be performed in a short time.

According to the present invention, since a suitable number of the second processing head magazines are provided so as to be movable in the other direction, many processing heads are stored in the second processing head magazine. Therefore, even if it is desired to exchange any processing head, it is possible to cope with it.
