BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turret punch press, and more particularly, to a turret punch press, which includes a plurality of dies on a turret circumference and a mold holder having exchangeable dies in a mold mounting area. The present invention relates to a turret punch press that is mounted and has improved positioning means for each mold.

[0002]

2. Description of the Related Art In a conventional turret punch press, a large number of dies are mounted on the circumference of a lower turret while being rotatably supported by a frame. The upper and lower turrets on which the multiple dies are mounted are provided with processing stations No. for the respective dies in order to index the respective dies to the processing positions. The mold mounting station No. selected from the processing station No. and indexed to the processing position, and the shot pin holes provided in the upper and lower turrets for indexing and positioning the mold mounting station No. to the processing position include, for example, In a relation of a symmetrical position about the turret rotation axis or a position at a predetermined angle, one shot pin provided on the frame is engaged with the shot pin hole to divide the die into a processing position. It is arranged to be put out.

Recently, the upper and lower turrets are provided with at least one mold mounting area for exchanging a mold by a mold exchanging device, and the mold mounting area is provided with a replaceable mold. A mold holder is mounted.

[0004]

However, when a mold holder having a mold which can be exchanged for the upper and lower turrets is used by mounting it in a mold mounting area, the mold holder is large and Since a shot pin hole cannot be provided in the mold holder, a separate mold cannot be mounted in a space symmetrical to the mold holder with respect to the rotation axis, resulting in wasted space.

In other words, when the replaceable mold provided in the mold holder for mold exchange is indexed and positioned at the position of the shot pin, the useless space is indexed to the machining position. Therefore, there is a problem that the mold cannot be mounted on the upper and lower turrets symmetrical to the holder for mold replacement, so that a space is wasted. The purpose of the present invention is to improve the above-mentioned problems, even when a mold holder having a replaceable mold is mounted in a mold-replaceable mold mounting area provided on a turret, Provided is a turret punch press in which a mold is mounted at a symmetrical position to eliminate useless space and that the die mounted at a symmetrical position of the mold holder can be accurately positioned even when indexed to a processing position. Is to do.

[0006]

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention mounts a large number of dies on a turret rotatably supported on a frame, and detaches and replaces the turret by an automatic die changing device. The turret is provided with a mold set mounting area for mounting a mold to be set, and a plurality of shot pin holes corresponding to the respective molds and the mold set mounting area are provided on an outer peripheral surface of the turret. A first shot pin device including a first shot pin capable of engaging with each of the shot pin holes and fixing the turret when the die and the mold set mounting area are indexed to the processing position and positioned. When the mold set mounting area and the first shot pin device are opposed to each other, a predetermined die that is indexed and positioned at the processing position is positioned at the processing position. Engages Yottopin hole is made by providing a second shot pin device provided with a second shot pins can secure the turret.

Is mounted with a mold holder 53 having a mold set 33 composed of a punch P and a die.

On the circumference of the upper and lower turrets 9, 11, the station No. Are attached, for example, from 1 to 24. In addition, for example, in FIG. 6, 17 and 22, a mold mounting area 37 is provided, and a mold holder 53 having a mold set 33 is mounted. 6,17,2
Normal punches P to 21 station numbers other than 2
Die D is mounted.

At the side positions of the upper and lower turrets 9 and 11, a plurality of shot pin holes 55 are provided at appropriate intervals corresponding to the punches P and dies D, for example, holes N in FIG.
o. 1 to 23 are formed. Further, a shot pin device 57 provided on the frame 3 is provided at a position A which is symmetrical to the processing position 15 with respect to the rotation axes of the upper and lower turrets 9 and 11. Since the specific configuration of the shot pin device 57 is already known,
Although the detailed description is omitted, the shot pin 61 is extended by the operation of the cylinder 59, and is engaged with the appropriate shot pin hole 55 of the hole No. to be positioned.
When the upper and lower turrets 9 and 11 are rotated to index the punch P and the die D to the processing position 15, the shot pin 61 is contracted by the operation of the cylinder 59 and the shot pin 61 is detached from the shot pin hole 55. Becomes

A plurality of the shot pin devices 57 are provided, and in the case of this embodiment, they are also provided at a position B which is appropriately shifted in phase from the position A. Further, the shot pin device 57 may be provided at a position C indicated by a two-dot chain line, or a plurality of shot pin devices may be provided at other positions.

FIG. 2 shows an example of indexing and positioning a die comprising a punch P and a die D at a processing position when the shot pin device 57 is provided at the positions A and B.

And rotate Station No. 1 is indexed to the machining position, and the cylinder 59 of the shot pin device 57 at the position A is operated to insert the shot pin 61 into the hole No. of the shot pin hole 55. Positioning will be carried out by engaging with 14. Similarly, the station No. When indexing and positioning the station numbers excluding 4, 9, and 19 to the processing position 15, accurate positioning is performed by engaging the shot pins 61 with the hole numbers of the shot pin holes 55 shown in FIG. be able to.

The mold holder 53 is provided in the mold mounting area 37.
Station No. to which is attached. Station Nos. 17, 22, and 6 at symmetrical positions about the rotation axis. 4,
When indexing and positioning 9, 19 to the machining position,
The upper and lower turrets 9 and 11 are rotated, and the mold holder 5 is rotated.
Station No. 3 to which No. 3 is mounted. 17,22,6
Is located on the position A side of the shot pin device 57,
The shot pin device 57 at the position A cannot be used. Therefore, in this case, the shot pin device 5 at the position B is used.
7 is operated, and the shot pin 61 is inserted into the hole No. Engagement with 15, 21 and 7 enables accurate positioning.

As described above, the upper and lower turrets 9 and 11 are provided with the mold mounting area 37 for performing the mold exchange, and the mold mounting area 37 is provided with the mold set 33 capable of exchanging the mold. In addition to mounting the mold holder 53 and providing a plurality of shot pin devices even when the shot pin holes 55 cannot be formed in the mold holder 53, each mold (punch P and die D) is indexed to the processing position 15. In addition to accurate positioning, the dies can be mounted on the upper and lower turrets 9 and 11 symmetrically with respect to the die holder 53, thereby eliminating unnecessary space.

Further, as shown in FIG. 3, the upper and lower turrets 9 and 11 are rotated, and the station No. In the case where 6, 17, 22 are indexed to the mold changing position 39, the shot pin holes 55
Hall No. 14, 22, and 5, respectively, are indexed to the A position side of the shot pin device 57, so that the cylinder 59 of the shot pin device 57 at the A position is operated, and the shot pin 61 is turned into the hole No. of the shot pin hole 55.
Engagement with 14, 22, 5 allows accurate positioning.

The present invention is not limited to the above-described embodiment, but can be implemented in other forms by making appropriate changes. For example, in this embodiment, the upper and lower turrets 9 and 11 are rotated synchronously to set the processing position 1
In the example described above, the shot pin device 57 is provided at the A position and the B position, which are the symmetrical positions of 5, and the die is indexed and positioned. It is possible to provide the shot pin device 57 to cope with the problem, and the upper and lower turrets 9 and 11 may be individually positioned without being synchronized.
