ス装置は上記したように構成されている。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to the accompanying drawings for the understanding of the present invention. The following embodiments are examples of embodying the present invention and are not of the nature to limit the technical scope of the present invention. Here, FIG. 1 is a schematic configuration diagram of a main part of a punching press device according to an embodiment of the present invention. In the punching press apparatus according to this embodiment, as shown in FIG. 1, the punching blade 7 is provided below the punch 6 which is driven up and down by an actuator (not shown).
Are arranged. The punching blade 7 has a skirt portion 7a that expands downward and a straight portion 7b that is perpendicular to the vertical direction.
And the upper blade edge portion of the straight portion 7b is formed in a predetermined punched shape. The straight portion 7b is formed by the punching blade 7 during punching work.
The hem portion 7a is a portion that guarantees the strength of the ridge, and the skirt portion 7a is designed in consideration of the ease of dropping the scraps by punching. A heater 8 for heating the punching blade 7 is provided around the straight portion 7b so as to surround the straight portion 7b. The heater 8 is arranged around the straight portion 7b of the punching blade 7 in consideration of more effectively preventing clogging of the scrap 9 in the straight portion 7b. Then, the film-like sheet 2 is placed on the upper part of the punching blade 7 as in the case of the conventional punching press device, and the backing plate 3 is further placed on the upper surface of the film-like sheet 2. In the punching press apparatus configured as described above, when the film-shaped sheet 2 is punched using a base material made of, for example, a polyester film as a base, the melting point of polyester is 2
Since the temperature is 63 ° C., when the temperature is raised to the vicinity thereof, the polyester melts and the residue adheres to the punching blade 7, and the removability of the punch residue 9 after punching deteriorates. Therefore, it is appropriate to adjust the heating temperature of the punching blade 7 at around 100 ° C., considering that the heat deformation temperature of polyester is 95 ° C. as standard. However, depending on the thickness and shape of the film sheet 2,
Needless to say, the optimum temperature changes depending on the material change. The punching press device according to the present embodiment is configured as described above.

ることもでる。Therefore, when the film-shaped sheet 2 made of, for example, polyester is punched into a predetermined shape by using the punching press device, the punching blade 7 is preheated to about 100 ° C. by the heater 8. In this state, the film-like sheet 2 is placed on the punching blade 7, and the film-like sheet 2 is punched by the punch 6 through the contact plate 3.
Is pressed by. As a result, the film-like sheet 2
Are punched into a predetermined shape. After being punched out as described above, the portion of the scrap 9 that comes into contact with the inner periphery of the punching blade 7 is heated to be thermally deformed and softened. As a result, the punch residue 9 is curved and the contact with the inner surface of the punching blade 7 is avoided, so that it easily slips out. As a result, the labor of removing the above-mentioned punch residue 9 from the punching blade 7 is saved and the workability is improved.
Incidentally, as shown in the figure, by vacuuming from below the punching blade 7, it becomes possible to more reliably collect the scraps 9. Further, in the punching press device according to the present embodiment, the punching work is performed while the punching blade 7 is heated as described above, so that the shape of the cut portion can be neatly aligned and the quality of the product can be improved.
