DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

FIG. 1A is a plan view showing one embodiment of the present invention, FIG. 1B is a detailed plan view showing one embodiment of the present invention, and FIG. FIG. 2 is a schematic side view of the entire structure of a turret punch press, FIG. 3A is a plan view showing an example of a product cutting portion, and FIG. 3B is an enlarged view of the cutting portion. FIG. 4 and FIG. 4 are explanatory diagrams showing examples of centering of a punch and a die.

First, an outline of a turret punch press as an example of the plate processing machine P will be described.

A plurality of punches and dies are mounted on the upper and lower turrets in a circumferential shape, and the desired punch and die are rotated by rotating the upper and lower turrets.
Index the die below the ram in the upper frame.

The carriage with clamp C for gripping the work can be moved and positioned in the X and Y directions by a servomotor and a ball screw, and the desired processing position on the work is moved and positioned between the punch and the die below the ram. Work is performed on the work by the operation of the ram through the punch and die (Fig. 2
reference).

The centering operation of the punch and the die before the working operation is the same as in the prior art in the present embodiment. As shown in FIG. 4, the centering jig (lower side) is inserted into the punch hole of the upper turret. To the lower turret, set the alignment tool (concave upward) on the lower turret die holder, and attach the die holder to the lower turret for centering adjustment so that both alignment tools are engaged. Adjust the alignment with bolts, then
The centering jig is removed, and a punch and a die for processing are set on the upper and lower turrets.

Next, this embodiment will be described with reference to the drawings.

The die 4 having the centering adjustment mechanism K according to the present invention has an adjustment die 1 including a die hole 1a in the center of a concave portion on the upper surface of the die 4, and adjustment pieces 2 on both sides thereof. .

The outer surface of the adjusting die 1 is inclined downward and divergent to form an inclined smooth surface, and the inner surface of the adjusting piece 2 is engaged with the inclined smooth surface of the outer surface of the adjusting die 1. It has a slidable inclined smooth surface. The outer surface of the adjusting piece 2 is slidable by engaging with the inner peripheral wall surface of the upper surface concave portion of the die 4. Note that at least two or more (four in this embodiment) adjustment pieces 2 are provided symmetrically about the adjustment die 1.

The adjusting screw 3 presses and penetrates the adjusting piece 2 and engages with the bottom of the concave portion of the die 4. By tightening or loosening the adjusting screw 3, the adjusting piece 2 is moved up and down to adjust. The position of the die 1 can be adjusted right and left.

When the adjusting screw 3 is rotated left and right, the adjusting screw 3 is provided with a scale on its head (see the enlarged view of FIG. 1 (b)). It can be finely adjusted by engaging with a zero point (see an enlarged view of FIG. 1B) serving as a base point of rotation engraved on the upper surface of the adjusting piece 2 that is screwed with and driven by the adjusting screw 3, The adjusting screw 3 is engraved on its scale so that the amount of lateral movement of the adjusting die 1 corresponding to the rotation angle of the adjusting screw 3 can be recognized.

The operation will be described based on the above configuration.

As described above, after the centering of the punch and the die is completed, punching is performed,
When sawing (microscopic unevenness), burrs, etc. occur during the overtaking process, the die 4 is taken out of the die holder 5, and after confirming the hole correcting direction, the adjusting screw 3 is moved to the right and left of the adjusting die 1. The adjustment screw 3 is rotated and adjusted in four places according to a scale (see an enlarged view of FIG. 1B) indicating a minute movement amount in which the movement amount can be recognized, and the adjustment piece 2 is moved up and down, thereby forming a die. A die centering adjustment mechanism K is constituted by an adjustment piece 2 having an inclined smooth surface and an adjusting screw 3 engaged with an adjustment die 1 having an inclined smooth surface that is symmetrical with respect to the hole 1a and has a divergently inclined inclined surface. Therefore, the adjusting die 1 and the adjusting piece 2 engage with each other to incline and slide on the contact surface. As a result, the adjusting die 1 is slightly moved in a desired direction to complete the centering adjustment of the die. .

As described above, in the centering operation of the die at the time of punching and aligning the die at the time of overtaking, the mounting bolt of the die holder is loosened as in the related art, and the worker goes under the striker to obtain the state of the core. The troublesome work of checking and aligning the center is unnecessary, and the centering adjustment mechanism K according to the present invention easily re-centers the core for correction at the time of overtaking without loosening the mounting bolts of the die holder. Is what you can do.

[0024]

According to the present invention, by newly providing the die centering adjustment mechanism in the die, it is possible to easily perform a difficult work for correction at the time of overtaking and to improve the working efficiency. It has the effect of being able to.
