It is movable in the X direction by the drive of 29, and the stopper 25 can be positioned at an arbitrary position.

The main body frame 5 includes a shear, a punch,
Alternatively, a turret table 33 provided with a plurality of dies 31 for performing bend processing is mounted rotatably and freely back and forth (Y direction). To move the turret table 33 back and forth, a handle 37 is provided on a part of an operation panel 35 attached to the front of the table 7. Therefore,
By rotating the handle 37 clockwise or counterclockwise, the turret table 33 can be operated in the Y direction.

Further, an upper frame is provided on the upper part of the main body frame 5.
39 is supported by the side frames 3R and 3L. The upper frame 39 has a ram for pressing the mold 31 indexed and positioned at a predetermined position for processing the workpiece W.

Shear, punch, or vent processing is performed at the position. The Y-axis position is appropriately adjusted by the handle 37.

Therefore, the operator first creates a program for machining the workpiece by operating the NC control panel 49, that is, a process program for positioning the sizing device 27, and numerically controls the servomotor 29 to sequentially execute the program. While abutting one end of the workpiece W against the stopper 25 whose position is changed for each process,
A predetermined processing operation is performed.

FIG. 5 is an explanatory view of an operation surface of the NC control panel 49, and FIG. 6 is an explanatory view of an operation procedure written on a nameplate attached close to the NC control panel 49.

In FIG. 5, on the operation surface of the NC control panel 49, buttons or key switches and indicators for editing or executing a program, such as an LED lamp for notifying an alarm or completion of positioning, are appropriately displayed using pictograms. It is arranged in order. "One process""Program""Shah"
"Punch", "Vent", "Dimensions (memory)", "Pitch", "Number", "Manual (←, →)", "Origin return", "Start"
Each of the "ON", "OFF" and "STOP" switches has a lamp incorporated therein so as to be lit or flashed as appropriate. Hereinafter, a switch incorporating these lamps will be referred to as a "button" and a switch other than the "button" will be referred to as a "key".

 The general operating procedure is as shown in FIG.

That is, first, the no-fuse breaker on the back side of the electric box is turned on, the operation circuit key switch of the operation unit is turned on, the oil pressure is turned on, and the home return button is pressed, the home position of the sizing device 27 is returned. A return is made automatically.

Next, press the "one step" or "program" button. In the "one step", you can select the desired machining mode from shear, punch, and bend.
By pressing the start button, one-step processing can be performed.

In this case, the NC device incorporated in the NC control panel 49 performs positioning of the sizing device 27 to position the workpiece W at the input position, and various actuators, sensors,
For example, a process is performed in which a fitting signal of a shot pin for fixing the turret table 33 is input, a predetermined LED lamp is turned on according to a preset sequence, or a transition to the next operation is enabled. become.

On the other hand, when the "program" button is pressed, the lamp inside the switch is turned on, and the input of the program number is prompted. Then, when the operator inputs the program number, the predetermined program processing can be performed in the predetermined processing mode by the already edited program or by the program to be edited.

As for the cutting (single size) work, it is shown that the stopper is positioned by pressing the “shear” button, inputting a numerical value, and pressing the “start” button.

As for the punch (end face input) work, it is shown that the stopper is positioned by pressing the "punch" button, inputting the numerical value of the hole position, and pressing the "start" button.

As for the punching (pitch input) work, pressing the "punch" button, inputting numerical values of the hole position and the pitch, and pressing the "start" button indicates that the stopper is positioned.

As for the cutting (lot processing) work, pressing the "shear" button, inputting the dimensions and the number of cuts, and pressing the "start" button indicates that the stopper is positioned.

It should be noted that, as a precautionary note, it is shown that the lighting of the "start" and "stopper" buttons can be turned off by moving the stopper 25 with the manual command button during notch processing. The Y-axis positioning during drilling is a Y-axis handle.
At 37 it is shown to do.

 FIG. 7 shows a block diagram of the operation mode transition method.

The operation modes of this example are four types: an origin mode, a storage mode, an automatic mode, and a manual mode.

The origin mode is divided into "return to origin", "pause", and "end to return" operations.

The automatic mode is divided into “automatic operation” and “automatic stop”.

The manual mode is divided into "manual button on (axis moving)" and "(axis stop)".

Therefore, in this example, after defining each operation in each mode as described above, the transition from each operation to each operation can be performed in only one direction as indicated by an arrow, and the necessary transition Is to be automatically migrated.

As an example, first, when the origin return button is pressed for the operation of origin return, the “origin” button flashes and the mode becomes the origin return mode. So, "start" or "stop"
"One process""Program""Manual""Number""Pitch"
Press the button to stop temporarily. Also, after a pause,
When the "Origin" button is pressed, the operation returns to the origin. In these cases, the "origin" button is blinking because both are in the origin mode.

Next, after the return to origin is completed, "Dimensions (memory)""Oneprocess"
When the “program” and “number” buttons are pressed, the mode shifts to the storage mode.

In the storage mode, one-step operation and program input operation can be performed, and the operation can be shifted to the automatic mode by turning on the start button, and can be shifted to the manual mode by turning on the manual button.

In the manual mode, the mode can be shifted to the storage mode by turning on the pitch, one process, program, size, and number buttons.

In the automatic mode, it is possible to shift to the storage mode by operating buttons related to the pitch, one process, program, and number of programs.

As described above, in this example, it is possible to shift to a desired mode by operating an operation button related to the mode without providing a special mode selection operation button, and performing a required operation with a small number of operation buttons. Is what you can do.

 Next, a specific example of the operation will be described.

FIG. 8 is a flowchart showing an operation procedure of one process.

First, when "one step" is selected, the "one step" button lights up, and at the same time, to select the desired processing mode,
The buttons for “shear”, “punch”, and “bend” light up together to urge selection.

Therefore, if the operator selects, for example, "shear", only that continues to be turned on, and the buttons for other processes are turned off.

Therefore, next, when the dimension is input with the numeric keypad, the "input" key is pressed, and the "start" button is pressed, "start" is turned on and one-step work is started.

On the other hand, if the user presses the "start" button without pressing the "input" key after inputting the dimensions using the numeric keypad, it will be an alarm.

On the other hand, if you press the numeric keypad after selecting one process, the "shear", "punch", and "bend" for each processing mode go out, and even if you press the start button here, it will be an alarm, but then press the "input" key. When the start button is pressed, "start" lights up and the stopper 25 can be positioned. If the "delete" key is pressed in the middle, it is possible to return to the position of the intended machining mode selection command. These operations are effective when it is desired to simply move the stopper 25 once.

FIG. 9 is a flowchart of the program input operation method.

First, when the "program" button is turned on, the "program" blinks.

For new entry, use the numeric keys to enter the program number,
For example, when "7" is input, this value is displayed on the 7-segment display, the LED lamp provided above "set value" is turned on, and the button indicating each processing mode blinks.

Therefore, when the machining mode is selected, the dimension (memory) button blinks. Therefore, when data is input and the start button is pressed, "start" lights up, and the data of the first process is displayed on the set value display section. .

On the other hand, when recalling a stored program, after inputting a program number, for example, "5", using the numeric keypad, the stored setting data of the first step of the machining mode is displayed. Then, the blinking "program" button is not turned on, but the stopper 25 is positioned at the set value of the first step. If the input key is pressed before the start button is pressed and the process moving key is operated, the process shifts to the next or previous process.

In short, in this example, by turning on, blinking, and turning off the button or the LED lamp, it is possible to guide successive operations and easily perform one-step input and program input.

In addition, the seven-segment display indicating the number in the present example shown in FIG. 5 sets the number, and displays a value with a minus (-) sign when processing is continued after the set number is completed. It has become.

If the number is set in this way and the machining is continued after the end of the set number, the minus (-) sign indicates that the number display not only indicates the remaining number, but also indicates the remaining number. Since the number is also displayed, it cannot be indicated by a pictogram as "remaining". Further, a plus (+) sign cannot be used in the 7-segment display. Therefore, in the present embodiment, a minus (-) sign is added when displaying the number of processed pieces after the end of the set number, so that the rest can be easily grasped intuitively.

The present invention is not limited to the above embodiment, but can be implemented in an appropriate mode by making appropriate design changes.

[Effects of the Invention] As can be understood from the above description of the embodiments, the gist of the present invention is as described in the appended claims. The input is guided, so that the data can be easily input. However, in the present invention, the transition to various operation modes of the origin mode, the storage mode, the automatic mode, and the manual mode is performed in a special mode. It is possible to easily shift to a desired operation mode by operating an operation button related to the mode without requiring a selection operation button. Therefore, the number of operation buttons can be reduced.
