Height adjustment plate 1 as adjustment means for adjusting the set height of 0
1 is inserted, and a punch fixing screw member 13 is inserted into the screw hole portion 14 of the mold body 8-1.
The tip of the punch fixing screw member 13 is screwed into the screw hole 10 e of the punch 10. In addition, the mold body 8-1 includes:
Plate 8a that determines the setting direction of the marking die
Are fixed by a screw member 8b.

The other marking processing die assembly 9A, which is one of the lower processing dies 9, is a marking processing die 1 that receives a processing position in a plane with respect to the pressing force of the punch 10.
2 is provided.

Next, the operation of forming a positioning recess (marking) on the work 4 by the marking processing apparatus according to the present invention will be described with reference to FIGS. 3 and 5 to 8. FIG.

One of the marking processing die components 8A configured as described above is set in the upper processing die station 2, and the other marking processing die configuration 9A.
Is set in the lower processing die station 3, and the lower processing die stations 2 and 3 are controlled by the NC control (N
C program) to rotate according to the station number and the processing instruction to call the one and the other marking processing die components 8A and 9A, and the punch 10 and the marking processing die 12 are used to form the work 4 Up,
It is positioned below.

In this state, the punch 10 is pressed down from the top dead center 200 before pressing as shown in FIG.
01 is reached. At this time, the marking die 9 </ b> A receives a processed portion in a plane with respect to the pressing force of the punch 10. In this way, markings are performed by forming the depressions 20a and 20b in the work 4 as shown in FIG.

Then, as shown in FIG. 7, a rubber foot 100 is attached to the work 4 having been subjected to the marking process so as to match the depressions 20a and 20b. Labeling is performed by processing a vertical recess 20b with respect to a horizontal recess 20a, and aligning the labels 101, 1 with the recesses 20a, 20b.
02 is attached. Representative examples of the marking processing shape are shown in (1) to (10) of FIG.

In the above-mentioned one marking processing die structure 8A, the adjustment of the die set length (the adjustment of the set height of the punch 10) is performed by the number of the height adjustment plates 11.

One of the marking processing die structures 8A, which does not need to change the die set length, is shown in FIG.
The results are shown in (2) and (3).

In the marking die assembly 8A, the punch 10 for forming a marking shape is inserted into the mounting shaft insertion portion 15A of the punch mounting portion 15 of the die body 8-1.
And an elastic member 16 which is an automatic adjusting means for automatically adjusting the set height of the punch 10 is inserted. The flange insertion portion 15B of the punch mounting portion 15 has the punch 10 A flange 10c is inserted, and the flange 1

Therefore, when performing the marking process,
The stroke error generated between the strokes when the punch 10 of one of the marking processing mold components 8A is pressed and reaches the bottom dead center 201 from the top dead center 200 is caused by the elastic member 16.
Is relaxing. In this case, when the pressing force is transmitted to the elastic member 16 when the marking processing die structure 8A reaches the bottom dead center 201 and a certain force or more is transmitted, the elastic member 16 contracts. At this time, the flange 10 of the punch 10
c moves by the same amount as the amount of deflection of the elastic member 16 and escapes to the escape space 17, and the punch fixing screw member 13 slides in the opposite direction to the pressing direction. With these configurations, the depression 20
It is possible to avoid such a phenomenon that a and 20b are shallow or the depressions 20a and 20b are deep.

Regarding the direction of the pressing force and the processing method, the same effect can be obtained even if the upward and downward directions are reversed.
The description is omitted because it is obvious.
