Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a turret punch press device.

(Prior Art) Conventionally, a turret punch press device 1 is generally configured as shown in FIG. That is, a large number of punching punch dies 5 are attached to the upper turret 3, and dies 9 corresponding to the punch dies 5 are attached to the lower turret 7, so that the upper and lower turrets 3 and 7 rotate integrally. Then, a desired set of a large number of punch dies 5 and dies 9 is rotated immediately below the striker 11 to be positioned.

On the other hand, the work W is clamped on the material clamper 13,
By combining the movement of the carriage 15 to which the clamper 13 is attached in the front-rear direction and the movement of the carriage base 17 to which the carriage 15 is attached in the left-right direction, a predetermined processing site of the work W is provided immediately below the impactor 11. It is brought in and positioned between the punch die 5 and the die 9.

After the punch die 5 and the die 9 are positioned and the work W is positioned, the work W is punched into a desired shape by hitting the head portion of the punch die 5 with the hitting element 11.

(Problems to be solved by the invention) However, in such a conventional turret punch press device, by presetting a die selection procedure, desired punching can be performed on a work while automatically selecting a die. On the other hand, when punching of one shape is repeated several times between punching of different shapes, the same shape required for punching repeatedly. This means that many molds must be incorporated between molds of other shapes, and even though they are commonly used molds, there is a waste of having to prepare multiple molds. It was

The present invention has been made in view of such a conventional problem, and a die used for punching commonly performed during punching of some other dies is made into a subunit to form upper and lower turrets. It is installed in a different location, and whenever sub punching is needed, the sub die attached as this sub unit can be used to repeatedly punch the same shape, avoiding duplicate dies and simplifying die management. It is an object of the present invention to provide a turret punch press device that can be realized.

[Structure of the Invention] (Means for Solving the Problem) In the turret punch press device of the present invention, a sub mold holder is rotatably attached to a spindle at a position where the rotation range of the upper and lower turrets is offset, A sub-punch type and a corresponding sub-die are attached to the die so that they can be exchanged up and down, and the punch type of the upper and lower turrets, the punching position that is offset from the punching position of the die and the punch type of the upper and lower turrets and the die. A rotary drive device is provided for rotationally moving the sub die holder between the positions where the sub punch die and the sub die can be exchanged even during the punching operation.

(Operation) In the turret punch press device of the present invention, in the normal punching operation, the upper and lower turrets are rotated, and the work is punched between the punch die and the die that are sequentially mounted.

Then, if punching of a certain shape is required between punching of the upper and lower turret dies, the work is punched by the sub die of the sub punch die and the sub die.

Then, when the predetermined punching is completed, the punching by the molds of the upper and lower turrets is resumed, and the punching of a fixed shape is repeated by the sub-molding together with the required punching in the intervals of the normal punching work.

Further, when it becomes necessary to replace the sub mold, the sub mold holder is rotated to the replacement work position by the rotation driving device to replace the sub mold. At this time, even if the sub-die holder is being punched normally by the rotary drive device between the punch dies of the upper and lower turret and the die, the sub-die replacement work can be performed at a position that does not interfere with the punching work. I can do it.

(Embodiment) An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a front view of an embodiment of the present invention, and FIG. 2 is a plan view thereof. In the turret punch press apparatus 1 of this embodiment, a support shaft 21 is attached to a frame 19 on the front side of the turret punch press apparatus shown in FIG.
Is provided, and one end of the sub mold holder 23 is rotatably attached to the support shaft 21. And this sub mold holder
At the other end of 23, a sub punch die 25 is detachably attached on the upper side, and a sub die 27 is detachably attached on the lower side.

The sub die holder 23 is attached at a position where it does not interfere with the punching work by the punch die 5 and the die 9 of the upper and lower turrets 3 and 7 during its rotation. Further, the punching position C1 by the sub metal molds 25, 27 is offset by 1 from the punching position C2 by the metal molds 5, 9 on the turret 3, 7 side.

A rotary arm 29 is provided on the shaft side of the sub mold holder 23, and one end of a hydraulic cylinder device 31 as a rotary drive mechanism is coupled to the rotary arm 29. The other end of the hydraulic cylinder 31 is connected to the frame 19.

Reference numeral 33 denotes a sub-punch striker unit, and the sub-punch striker unit 35 is installed at a position in the sub-punch striker unit 33 where the sub-punch die 25 can be hit exactly. 37 is a shot pin cylinder, and the time when the shot pin 39 of this shot pin cylinder 37 falls into the receiving recess 41 of the sub die holder 23 is the punching position.

Next, the operation of the turret punch press device having the above configuration will be described.

Multiple punch dies 5, mounted on the upper and lower turrets 3, 7,
Punching work with 5, ... And dies corresponding to these, 7, 7 ... Is the same as the conventional one.

When punching with the sub dies 25 and 27, the clamper 13 shown in FIG. 3 clamps the work W,
By moving the carriage 15 and the carriage base 17 in the front-rear and left-right directions, a predetermined part of the work W is moved between the upper and lower sub-punch dies 25 and 27 and fixed, and the sub-punch striker 35 is used to fix the sub-punch dies 25. Punching is done by hitting the head.

When it is necessary to replace the sub-punch mold 25 and the sub-die 27, the hydraulic cylinder 31 as the rotation driving device is driven to rotate the rotating arm 29 to the outside. The punching position P1 is moved to the outside by about 90 degrees to the mold replacement position P2, where the sub molds 25 and 27 are replaced using, for example, an automatic mold replacement device.

At this time, the sub mold holder 23 and the sub molds 25 and 27 are attached so as not to interfere with the punching work using the upper and lower turrets 3 and 7, and are designed to be rotated and moved. Even if the exchanging work of 27 and 27 is being performed, the punching work using the original punch die 5 and die 9 using the upper and lower turrets 3 and 7 can be continued.

When the replacement work of the sub molds 25 and 27 is completed, the hydraulic cylinder 31 is driven again to draw the rotating arm 29, and accordingly, the sub mold holder 23 is rotated from the replacement position P2 to the punching position P1, and the next Prepare for punching by sub molds 25 and 27. The positioning at this time is determined as the position where the shot pin 39 falls into the receiving recess 41.

In the above embodiment, the hydraulic cylinder was used as the rotary drive device, but this may be a double crank mechanism or an OCTO system, and if the sub mold holder can be rotationally moved and positioned, that mechanism is particularly preferable. Is not limited.

[Effect of the Invention] As described above, according to the present invention, the punch dies attached to the upper and lower turrets and the die are rotated separately from the punch dies of the upper and lower turrets and the die at a position not disturbing the punching work. When the sub punch die and the sub die are detachably attached to the driven sub die holder, and when punching with a die having a different shape from the normal punching work is repeatedly performed, this sub punch die and the sub die are used. Since punching is performed repeatedly each time, even if it is necessary to repeat punching the same shape several times between punching other shapes as in the past, the order of punching on the upper and lower turrets It is not necessary to prepare duplicate molds of the same shape corresponding to the above, it is possible to reduce waste and manage molds. It can be simplified. In addition, it is necessary to interrupt the original punching work to replace the sub mold because it is possible to rotate the sub mold by rotating it in a position that does not interfere even during the punching work using the normal mold. It is possible to improve work efficiency.
