DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a die changing system in a plate processing machine such as a turret punch press having an automatic die changing function.

[0002]

2. Description of the Related Art Conventionally, a plate material processing machine such as a turret punch press having an automatic die changing function has a tool stocker, a die changing arm, etc., and can automatically change dies. Achieving skill.

[0003]

However, in the above-described conventional example, when the mold in use is worn out, a mold that needs to be replaced may be found and re-grinding may be required. There is a problem that must be stopped temporarily.

The present invention has been made in view of the above points, and provides a mold exchanging system in which an auxiliary stand is arranged so that the mold can be exchanged without stopping the operation of the machine. With the goal.

[0005]

The present invention can solve the above-mentioned problems by providing the following constitution.

(1) In a plate processing machine such as a turret punch press having an automatic die changing function, an auxiliary stand is provided at a position where it can operate in cooperation with a die changing arm, and is stored in the auxiliary stand. A mold changing system, wherein a sensor for detecting operation of a ram is provided to replace a regenerated or new mold, and the information can be replaced without stopping the machine on an appropriate basis.

(2) The auxiliary stand has a space for receiving a remanufactured or new die and a space for receiving a worn die after use. .

(3) The sensor detects the number of ram hits, and outputs a program, mold data, memory RAM, CP
The mold exchanging system according to the above item (1), wherein information is exchanged with a control unit having a U and a display unit CRT, and a notification of an appropriate exchange time can be made in accordance with a type of the mold.

[0009]

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

FIG. 1A is a plan view showing an example of an arrangement according to the present invention, FIG. 1B is an explanatory view showing an example of the configuration of an auxiliary stand, and FIG. 2 is a block diagram showing a control system for a mold changing operation. FIG. 3 is a schematic side view of a main part of a turret punch press having an automatic die changing function.

Referring to the drawings, 1 is an upper turret, 2 is a lower turret, 3 is a mold magazine (tool stocker), 4 is a mold changing arm, 5 is an auxiliary stand, 7 is a work table, and P is an example. Turret punch press.

FIG. 1 shows that the exchange of dies is easy.
The case of a turret structure in which the diameter of the lower turret 2 is larger than the diameter of the upper turret 1 is shown. In addition to the mold magazine 3 and the mold changing arm 4, the auxiliary stand 5 according to the present invention is operated by the mold changing arm 4. Arranged in the area, for example, FIG.
As shown in (b), the position of the reference sign of the auxiliary stand 5 is used as a space for a recycled or new mold, and the opposed position is used as a space for a worn mold.

Referring to FIG. 2, the control device is equipped with a central processing unit CPU, a RAM as a memory, mold data, programs, etc., a CRT as a display means, a keyboard as a manual operation input means, and a RAM. A sensor that detects and counts the number of hits is provided, collated with the mold data in the control device, and the operator is notified of the mold replacement time by displaying the information on a CRT as display means,
By pressing the replacement timing command SW, the die changing arm adjusts the rotation amount of the drive motor in accordance with a command from the control device, so that the die changing operation can be performed within a predetermined range of the auxiliary stand. .

The control device is configured to transmit commands to each actuator, for example, ram drive, turret rotation, X and Y movement of the work, normal die changing arm operation, and die magazine. ing.

FIG. 3 is a schematic side view showing an example of a turret punch press with an automatic mold changing function that has already been developed. The turret body P shows a case where the turret structure is as described above. 8 is a clamping device. The other reference numerals are the same as those described above, and will not be described.

The operation will be described based on the above configuration.

First, by using the mold use time management, the mold indicating the replacement time by the mold data displayed on the CRT as the information transmitted from the control device is reproduced by the auxiliary stand 5 as shown in FIG. By setting the used or new mold in the space for inserting the new mold and pressing the exchange time command SW, the mold exchange arm 4 is operated to remove the worn mold from the press body P and to use the auxiliary stand 5. The worn mold is placed in the space where the worn mold is to be placed, and then the recycled or new mold is clamped from the space of the auxiliary stand 5 by the mold exchanging arm 4 and carried to a predetermined position of the main body turret and set. The worn mold placed in the space position is sent to the regrinding process and stocked as the next preparation, and the mold to be replaced next is set in the empty space. The above operation is repeatedly performed.

Alternatively, during the machining with the turret punch press P, the mold whose replacement time is determined by the sensor count is
The mold changing arm 4 is pulled out from the upper and lower turrets 1 and 2,
You may make it return to the auxiliary stand 5.

[0019]

According to the present invention, by disposing the auxiliary stand, it is possible to replace the mold without stopping the operation of the machine, thereby improving the production efficiency and further reducing the cost.
