Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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 in which dies at all stations on the turret can be rotated.

[0002]

2. Description of the Related Art Conventionally, a turret punch press as a single machine (e.g., corresponding to FIG. 1) has, as is well known, an upper turret 6 and a lower turret in which a punch P and a die D opposed to each other are arranged. 7.

On the upper turret 6 and the lower turret 7, a mold having a large capacity of a punch P and a die D, for example,
Eight to seventy molds are stored.

[0004] These molds are rotatable,
Processing in different directions can be performed with one mold.

A turret punch press with a mold changing device (corresponding to, for example, FIG. 10) has a storage turret on the side thereof.

[0006] Similarly, this storage turret accommodates a large number of dies including punches P and dies D, for example, 224 dies, and two sets of dies of the same type, for example, 0.
And 90 °.

[0007]

[Problems to be solved by the invention]

However, the conventional turret punch press described above has the following problems.

(1) Problems of turret punch press as a single machine.

As described above, in the conventional turret punch press, on the turrets 6 and 7 (FIG. 1),
For example, 58 to 70 molds are stored in all stations, and these molds are rotatable.

However, among all the stations, only two to four molds are rotatable, and the number is extremely small.

As a result, there is a problem that the operating efficiency is low.

For example, as shown in FIG. 12, a work W has a hole A having a size of 5 mm × 30 mm and a hole A having a size of 9 mm.
A hole B of the same size forming an angle of 0 ° may be drilled.

In this case, at a station other than, for example, two to four rotatable molds, 5 mm ×
A 30 mm mold must be placed at 0 ° and 90 °.

That is, in order to form the holes A and B (FIG. 12), a mold of the same type of 5 mm × 30 mm is set at 0 ° and 9 °.
0 sets have to be arranged, which takes time and costs.

Also, since a mold of the same type of 5 mm × 30 mm is stored on the turrets 6 and 7, other types of dies cannot be stored, and the storage efficiency of the dies decreases.

Further, the arrangement of the dies must be changed every time the processing is performed, so that the number of times the dies are set up before the processing is increased.

(2) Problems of a turret punch press with a mold changing device.

As described above, the storage turret (FIG. 10) contains, for example, 224 molds.

However, of the 224 dies, the same type of dies must be arranged for two sets of 0 ° and 90 °, and other types of dies cannot be accommodated.

Therefore, also in this case, the storage efficiency of the mold is reduced.

Also, as described in (1), in a turret punch press as a single machine, the mold storage efficiency on the turret is low, so that the turret punch press and the storage turret (FIG. 10) are frequently used. The mold exchange is performed between the two.

As a result, the mold changing time becomes longer (for example, 30 seconds to 60 seconds per mold), and the original machining time is reduced accordingly.

That is, in the turret punch press with the die changing device, the operation efficiency is low as in the turret punch press as a single machine.

An object of the present invention is to improve the operating efficiency of a turret punch press by enabling dies at all stations on the turret to rotate.

[0026]

According to the present invention, there is provided a punch rotating apparatus 100, a die rotating apparatus 200, and a die returning apparatus 300, as shown in FIGS. Then, the upper turret 6 and the lower turret 7 are rotated, and the plurality of radial punches P and dies D including the desired punch P and die D are positioned below the punch rotating device 100 and above the die rotating device 200, respectively. Then, a desired punch P on the upper turret 6 is selected by the punch rotating device 100, rotated by a predetermined angle, and then returned to the upper turret 6, and a desired die on the lower turret 7 is rotated by the die rotating device 200. A turret punch press is provided, wherein D is selected, rotated by a predetermined angle, and then returned on the lower turret 7 in cooperation with the die return device 300.

Therefore, according to the structure of the present invention, as shown in FIG. 1, for example, the punch rotating device 100 is mounted on the upper frame 1, the die rotating device 200 is mounted on the lower frame 15, and the die returning device 300 is mounted on the upper frame 1. Respectively, and by rotating the upper turret 6 and the lower turret 7, a plurality of punches P and dies D in the radial direction including the desired punch P and die D are obtained (FIG. 2).
, And above the die rotating device 200, respectively, and by using these devices 100, 200, and 300, desired dies P and D are selected for all the stations of each turret 6 and 7, and are set to predetermined positions. The turrets 6 and 7 can be returned after being rotated by an angle of.

Therefore, for example, a hole A shown in FIG.
5 mm x 30 mm
Only one set of the dies P and D is placed on the turrets 6 and 7 (FIG. 1), and the punch rotating device 100, the die rotating device 200, and the die returning device 3 according to the present invention described above.
If 00 is used, the molds P and D for one set are set to 0 °
And 90 ° rotation, the time and cost are greatly reduced, and many types of dies P and D can be stored on the turrets 6 and 7 to increase the efficiency of storing the dies. Since automatic rotation is enabled for all stations, the mold setup time is shortened, and eventually the operation efficiency is improved.

On the other hand, the punch rotating device 1 according to the present invention
00, the die rotating device 200, and the die returning device 300, the dies in all the stations on the turret can be rotated, so that in the turret punch press with the die changing device (FIG. 10), The 224 molds accommodated in the turret need not be arranged in two sets of 0 ° and 90 ° for molds of the same type, for example, as in the conventional case. Therefore, more types of molds can be stored in the storage turret, and the mold storage efficiency is improved, and the turret punch of the turret punch press as a single machine (FIG. 1) is improved. Since the number of mold exchanges between the press and the storage turret (FIG. 10) is also reduced, the entire mold exchange time is shortened accordingly, and the operating efficiency is likewise improved. .

That is, in the turret punch press, the dies at all the stations on the turret are made rotatable, whereby the operating efficiency can be improved.
