Abstract

PROBLEM TO BE SOLVED: To prevent preparing NC data being used for a die, the angle of which is impossible for attaching, and to enable NC data to be prepared so that it may meet with an actual angle for attaching the die. SOLUTION: From a station key information file 43, where angle information of a key/a key groove of each turret station in an upper and lower turret part are stored, and a die key information file 45 on the key/key groove of each die, the angle with which the die can be attached to the upper and lower turret is deduced. To the deduced angle of the die attachable to the press, the die being used is discriminated as to whether or not it can be attached with the required angle. When the die is discriminated as being not attachable, the die is discriminated as to whether or not it can be attached with an alternative angle. When the die is discriminated as being not attachable, the turret station, to which the die can be attached, is retrieved from the die key information file 45 and station key information file 43.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for determining a mounting angle of a die in a turret punch press.

[0002]

2. Description of the Related Art Conventionally, in a turret punch press,
The angle at which the mold composed of the combination of the punch and the die was mounted on the upper and lower turrets was such that the key groove 101 provided on the punch and the die was provided at the turret mold station as shown in FIG. Positioning is performed by matching the key 103. For example, the mold is provided with key grooves 101 in a plurality of directions so that the mold can be mounted at various angles.

As shown in FIGS. 10A to 10C, the direction of the key 103 and the number and direction of the key groove 101 differ depending on the mold and the turret, and can be custom-made.

[0004] Conventional automatic programming devices and terminals, N
In the C device, the turret has keys 103 and key grooves 10
Considering only the presence / absence of the key 1, the key 103 and the key groove 10
The turret having no 1 is simply processed so that a shape mold such as a square or a long angle cannot be mounted. That is, the angle at which the mold is mounted on the turret is configured to be freely set by the user.

The mounting angle of the mold (mold angle) is, for example, as shown in the right side of FIG. The counterclockwise direction is defined as positive.

[0006]

Conventionally, the mold angle at which the mold is set on the turret is specified by mold information attached to the NC data. However, there are cases where the mold cannot be actually set at the mounting angle of the mold set by the automatic programming device. For example, referring to FIG. 11, the mold angle is 0 ° and the keyway 10 of the turret is formed.
Since 1 is at 180 ° and 270 °, the mold cannot be mounted.

In the above case, since the mold is symmetrical, the mold is turned at an alternative angle, that is, 180 ° in the plus direction as shown in FIG. It can be changed and mounted for processing.

However, when the mold is not symmetrical as shown in FIG. 13, the mold cannot be mounted at an alternative angle, so that the NC data is adjusted to the angle at which the mold can be mounted. Need to be corrected. However, in the related art, since the mounting angle of the turret of the mold cannot be determined on the automatic programming device side, there is a problem that the above-described problem is noticed for the first time during actual machining.

Further, when registering the possessed molds in the memory of the control device, a plurality of mold mounting angle candidates can be set as shown in FIG. However, as described above, since the direction and the number of the key grooves 101 are different depending on the turret station, there is a problem that the key grooves 101 cannot be mounted as set.

For example, as shown in FIG. 15, when the direction of the key groove 101 of the turret is 0 ° and 90 °, the mold can be mounted at a mounting angle of 0 ° and 90 °. is there. However, as shown in FIG. 16, when the direction of the key groove 101 of the turret is provided at 180 ° and 270 °, the mounting angle of the mold is 0 ° and the mounting is impossible at 90 °. .

Referring to FIG. 8, a turret punch press 1 according to the present embodiment has a frame structure in which both sides of an upper frame 9 are supported by side frames 5 and 7 erected on both sides of a base 3. It is configured. At the lower part of the upper frame 9, a disk-shaped upper turret 11 having various kinds of punches P detachably mounted is rotatably mounted. On the upper surface of the base 3, a lower turret 13 facing the upper turret 11 is rotatably mounted. On the lower turret 13, a number of dies D facing various types of punches P are arranged in an arc shape. And it is detachably mounted. The axis of the upper turret 11 and the lower turret 1

A striker 17 is provided to be vertically movable. The striker 17 is connected to a hydraulic cylinder 19 as a driving device provided in the upper frame 9 via, for example, a ram 21 (a pressing member).

The punch P indexed and positioned below the ram 21 by the rotation of the upper turret 11 and the lower turret 13 is pressed by the ram 21.

The turret punch press 1 is provided with a work W movement positioning device 23 for moving and positioning the work W in the front, rear, left and right directions. Is provided with a carriage base 25 that is movable in the Y-axis direction (the left-right direction in FIG. 8).

This moving positioning device 23 is
And positions the work W at a desired position between the punch P and the die D.

Therefore, after positioning the plate-shaped work W between the punch P mounted on the turret punch press 1 and the die D mounted on the lower turret 13, the ram 21
As a result, the work is punched by the punch P and the die D.

A method and an apparatus for determining a mounting angle of a mold, which is a main part of an embodiment of the present invention, will be described with reference to the drawings.

Referring to FIG. 7, in the control device 15, an input device 33 such as a keyboard and a display device 35 such as a CRT are electrically connected to a CPU 31 as a central processing unit.

The CPU 31 has an input device 3
A machining program file 37 for storing data such as a machining program inputted from the station 3; and a station for storing station key information comprising angle information of the key 39 or key groove 41 for each turret station in the upper and lower turrets 11, 13. A key information file 43 and a die key information file 4 for storing die key information on the key 39 or the key groove 41 for each punch P and each die D.
5 and a processing unit 4 to be described later based on the key information of the key information file 47.
Holding information memory 5 in which a mountable angle information file 51 for storing the mountable angle information calculated by step 9 is stored.
3 are electrically connected. Incidentally, the above-mentioned holding information memory 53 is desirably a nonvolatile memory.

The above-mentioned CPU 31 stores a mold composed of a combination of a punch P and a die D in the upper and lower turrets 11 and 13 based on the key information of the station key information file 43 and the mold key information file 45. An arithmetic processing unit 49 for calculating a mold mountable angle that can be mounted on the turret station, and determining whether or not the used mold can be mounted at a desired angle with respect to the mold mountable angle determined by the arithmetic processing unit 49. In addition, a determination unit 55 that determines whether or not the used mold can be mounted at an alternative angle when the mounting cannot be performed in this determination is electrically connected.

Further, when it is determined by the determination section 55 that mounting is not possible even if the substitute angle is determined by the determination section 55, the CPU 31 uses the key information of the mold key information file 45 and the station key information file 43 to determine the use of the key. A mountable station search determination unit 57 that searches for a turret station to which a mold can be mounted and determines whether or not there is a turret station to which the mold can be mounted is electrically connected.

With the above configuration, the mold key information and the turret station key information are input by the input device 33,
It is stored in the mold key information file 45 and the station key information file 43 in the possession information memory 53, and a so-called possession information registration process is performed.

Next, the mold mounting angle determination processing includes four processing steps of a mounting angle determination processing step, a mounting enable / disable determination processing step, an alternative angle determination processing step, and a mounting station search processing step. You.

Referring to FIG. 1, in the mountable angle determining process, a key information file 4 including a station key information file 43 and a mold key information file 45 is provided.
7, the mold mountable angle at which the mold composed of the combination of the punch P and the die D can be mounted on the upper and lower turrets 11 and 13 is calculated and determined, and is stored in the mountable angle information file 51.

More specifically, referring to FIG. 2, the punch P and the die D are separately provided with the keys 39 of the turret station.
The difference between the angle of the key groove 41 and the angle of the key 39 / key groove 41 of the mold is obtained by the arithmetic processing unit 49 in FIG.
The obtained numerical value is the mounting angle at which the punch P and the die D can be mounted on the turret station.

That is, the method of obtaining the mounting angle of the punch P is as follows.
Since the key position of the turret station on the punch side is 0 ° and the positions of the key grooves 41 of the punch P are 0 ° and 90 °,
Punch P can be installed at 0 °, and Punch P is -90 °
It can be mounted by being turned in the direction (90 ° clockwise). Therefore, the mounting angle of the punch P is calculated by a simple calculation as shown in FIG.
90 = 270 ° is required. Note that 0 ° is 3 in calculation.
Replaced by 60 °.

On the other hand, the method of determining the mounting angle of the die D is as follows.
At 0 °, 180 °, and 270 °, the position of the key 39 of the die D is 0 °, so that the mounting angle of the die D is 0-0 = 0 as shown in FIG. 0 °
90-0 = 90 °, 180-0 = 180 °, and 2
70-0 = 270 ° is required.

Accordingly, the common angle between the mounting angle of the punch P and the mounting angle of the die D is the mountable angle of the mold. Therefore, the obtained wearable angle information is 0 ° or 270 °.

Referring to FIG. 1 again, the mounting unit 55 determines the mounting availability / inability, the alternative angle determining process, and the mounting based on the information in the mounting angle information file 51 and the machining program file 37. A possible station search processing step is performed.

Referring to FIGS. 1 and 3, a machining program including data of a desired mounting angle of a die to be used is inputted by the input device 33 and stored in the machining program file 37 of the possession information memory 53. (Step S
1).

Referring to FIG. 3, in the mounting possible / impossible discriminating process, the die to be used based on the machining program is determined based on the mold mountable angle determined in the mounting angle determining process. It is determined whether the camera can be mounted at a desired angle (step S2).

If it is determined by the determination unit 55 that mounting is possible in the mounting possible / impossible determination processing step, the mold mounting angle and the turret station are determined, and the process ends. However, when it is determined by the determination unit 55 that mounting is impossible, the process proceeds to an alternative angle indexing process (step S3).

In the alternative angle determining process, it is determined whether or not the used mold can be mounted on the turret station at the alternative angle (step S4). The substitute angle refers to a substitute angle at which the same processing can be performed. For example, a substitute angle of 0 ° in the oblong shape shown in FIG. 4A is shown in FIG. 4B. 180 ° as if

The above-mentioned replacement angle differs depending on the shape of the mold, and FIG. 5 shows an example of the replacement angle of each mold. In FIG. 5, "ALL" is a mold having no directivity, so that all the mountable angles are replaceable angles. “Impossible” refers to a shape that cannot be mounted at an alternative angle.

Referring to FIG. 6, there is shown an example of determining an alternative angle. Fig. 5
If the angle obtained by adding or subtracting an integral multiple of the substitute angle for each mold shape as shown in (1) matches the mold mountable angle, this coincident angle becomes the substitute angle.

For example, since the mold mountable angles of the turret and the mold shown in FIG. 6A are 180 ° and 270 °, as shown in FIG. If the mounting angle is 90 °, mounting is not possible. However, since the replacement angle of the long-angle mold is 180 ° as shown in FIG. 5, 90 ° (the angle to be mounted) + 180 ° = 270 ° as shown in FIG. 6C. It matches the mold mountable angle. Therefore, the replacement angle is 2
70 °.

Referring to FIG. 3, when it is determined in the above-described alternative angle indexing process that the mounting is possible by the determining unit 55, the mold mounting angle and the turret station are determined, and the process is terminated. However, when the determination section 55 determines that mounting is not possible, the process proceeds to a mounting-possible station search processing step (step S5).

In the mountable station search processing step,
The moldable key information file 45 and the station key information file 43
Then, another turret station to which a mold to be used can be attached is searched from the key information (step S6).

The turret station that can be mounted is searched by the mountable station search determining section 57 in the above-described mountable station search processing step, and if it is determined that there is a turret station that can be mounted, the mold mounting angle and the turret station are changed. The decision is made and the process ends.
However, when the search is not performed, it is determined that it is impossible to mount the mold at the set angle at which the mold is to be mounted, and the mounting failure (error) is displayed on the display device 35 as shown in FIG. 1 (steps S7 and S8). ). In this case, the mold mounting angle determination process is performed again from the beginning, instead of using a mold that can be used.

As described above, in the automatic programming device, it is possible to prevent an error in creating NC data using an angle at which a mold cannot be mounted. Also,
If the mold cannot be mounted, an alternative angle is calculated and a mountable station is searched, so that it is possible to create NC data at an angle at which the mold can be actually mounted.

Also, in the terminal and the NC device, it is possible to determine whether or not the mold can be mounted on the turret at a specified angle. Turret stations can be searched.

The present invention is not limited to the above-described embodiment of the present invention, but can be embodied in other forms by making appropriate changes.

In the case where the turret punch press having the automatic mold changing (ATC) function can change the mounting angle of the dies, the turret punch press is required to have the dies mounting angle given by the NC data or the information on the used dies. Therefore, it is necessary to determine in advance whether the camera can be mounted. In this case, by using the mold mounting angle determination processing method and apparatus according to the embodiment of the present invention, not only determination of mounting possible / impossible, but also, if it is determined that mounting is not possible, changing to an alternative angle and mounting. It is possible to search for a mountable turret station and mount it on this turret station.

[0052]

As will be understood from the above description of the embodiments of the present invention, according to the first aspect of the present invention, the automatic programming device uses the NC data used at an angle at which the mold cannot be mounted. It is possible to prevent mistakes made. If the mold cannot be mounted, an alternative angle is calculated and a mountable station is searched, so that the NC data can be created at an angle at which the mold can be actually mounted.

In the terminal and the NC device, it is possible to determine whether or not the mold can be mounted on the turret at a designated angle. If the mold cannot be mounted, an alternative angle can be determined, or the turret station can be mounted. Can be searched.

According to the second aspect of the present invention, the effect is the same as that of the second aspect, and the automatic programming device prevents an error in creating NC data using an angle at which a mold cannot be mounted. be able to. If the mold cannot be mounted, an alternative angle is calculated and a mountable station is searched, so that the NC data can be created at an angle at which the mold can be actually mounted.

Further, in the terminal and the NC device, it is possible to determine whether or not the mold can be mounted on the turret at a designated angle. Can be searched.
