CONSTITUTION:The NC program editing means provides the numerically changable attitude about the depth axis when the controller of the depth axis and the projecting gauge of the bending machine is controlled numerically. Therefore, when the new data is generated, or when the condition change is generated, the correction can be made with the try bending. The material information, the die changing information, the bending producer information, etc., required for executing the above bending program are edited as the working information. And the information managing means stores and reserves the above bending program and the working information for each the products unit with the centralization together. On the time when the proper products is worked, the bending program is transmitted to the NC device of the bending machine and also the other working information is provided to the operator in the form being able to refer.

Description

[Detailed description of the invention] (Purpose of invention) (Industrial application field) The present invention relates to a folding data editing device.

(Prior art) A bending machine such as a press brake places a plate-shaped workpiece between a punch and a die, and moves the two molds relatively close to each other, thereby shaping the workpiece into a V-shaped cross section. Bend it so that it looks like this.

The control method for this type of bending machine is that one of the punch or die is a movable die, the other die is a fixed die, and the movable die is moved to a preset target position relative to the fixed die. A common mold positioning method involves positioning and bending the workpiece at a predetermined angle.

Therefore, when bending a workpiece using this mold positioning method, the positioning position of the movable mold must be designated in conjunction with the designation of the positioning position of a butting device such as a backgauge device that determines the bending position of the workpiece. The drive shaft of the abutting device is called the L axis, and the drive shaft of the moving mold (I) is called the Debsnoyu.

Therefore, in the past, it was difficult to determine in what order each bending position should be performed for a workpiece that had to be bent at multiple locations such as a beam spot, and how to perform the bending process using a movable die and N that specifies which position of the abutting device is to be controlled.
The C program was edited on-site, and the edited NC program was given to the NC device that controlled the bending machine.

Here, editing the NC program on-site is as follows:
This is because the above-described bending process requires trial bending work when setting the D-axis target position.

That is, D-axis positioning is 1. <The frame that supports the punch and die vertically may bend due to the pressure applied, the positioning position may shift due to rare differences in the thickness of the workpiece or the shape of the mold, and changes in the tensile strength of the workpiece may affect the pressure applied. positioning accuracy varies depending on the temperature of the oil supplied to the cylinder device for driving the D-axis, etc.
This is because at least the final axis target position is determined at the site, since this affects the D-axis positioning accuracy and, by extension, the bending accuracy.

With such bending machines that edit NC programs on-site, the NC programs are edited on-site, so information indicating the bending procedure, such as the bending shape shown in the order of the process, is not created. First, the steps are sequentially reproduced solely from the memory of the operator who edited the NC program.

Therefore, with conventional bending data editing methods, bending process and other processing information is only fully understood by the operator who created the NC program, and in bending processes that involve complex bending processes, the operator forgets the bending process and other processing information. Or, due to a misunderstanding, there was a problem that it could not be reproduced without referring to the NC program.

Incidentally, when the bending process is carried out by manually supplying the workpiece, the end of the workpiece must be brought into contact with the stopper of the abutting device, and therefore large and small registration marks must be applied repeatedly. If the process is not clear, it will no longer be possible to do the work efficiently.

Conventionally, in order to improve these problems, a process diagram was written on a piece of paper separately from the creation of the NC program, and it was pasted on a part of the operating device or placed horizontally for the operator to refer to. However, there were problems in that hand-drawn process charts were difficult to read and easy to use, and it was difficult to accurately write down material information and mold information, resulting in a lack of information.

We also have an automatic programming method that fully automatically creates an NC program including a process diagram by inputting the product shape, sends it to the NC device that controls the bending machine, and displays the processing information on the CRT attached to the NC device. However, as mentioned above, there are cases where the bending process must be done manually, and this automatic programming method
The problem was that it was not possible to respond adequately in all cases.

(Problem to be solved by the invention) As mentioned above, in the conventional folding data editing method, the method of handwriting the process diagram requires a lot of time to create the process diagram, lacks information, and is not easy to use. There was a problem that the automatic block ramming method could not handle all cases.

SUMMARY OF THE INVENTION Therefore, the present invention provides a bending data editing device that allows an operator to easily create processing information such as process drawings when manually editing an NC program, and allows an operator to edit easy-to-use bending data. The purpose is to

[Structure of the Invention] (Means for Solving the Problems) The present invention for solving the above problems numerically defines the depth axis of the bending machine and the control position of the abutment gauge along an arbitrarily determined process. NC program editing means for editing a bending program for a depth axis in a manner in which numerical values can be changed; and material information necessary for executing the bending program.

Mold replacement information 1 A processing information editing means for editing processing information such as bending procedure information, and a bending unit that centrally stores and stores the bending program and processing information for each product and bends the product when processing the product. The present invention is characterized by comprising a bending information management means that transmits the bending program to the NC device of the processing machine and displays or prints other processing information in a form that can be referenced by the operator.

(Function) In the bending data editing device of the present invention, with the above configuration, N
The C program editing means edits a bending program for numerically specifying the depth axis and abutment gauge control device of the bending machine along an arbitrarily determined process in such a manner that the depth axis can be changed numerically. The reason why numerical values can be changed regarding the depth axis is to enable correction by trial bending when new data is generated or when conditions change.

Further, the processing information editing means edits processing information such as material information, mold exchange information 1 and bending procedure information necessary for executing the bending program.

Then, the bending information management means centrally stores and stores the bending program and processing information for each product, and when processing the product, the NC of the bending machine that bends the product is used.
The bending program is transferred to the device, and other machining information is displayed or printed in a form that can be referenced by the operator.

Processing information that can be automatically edited may be automatically edited. For example, mold shape information can be automatically generated by inputting a mold name. Furthermore, the process diagram can be automatically edited by adapting the process edited by the NC program editing means to the workpiece shape.

(Embodiment) In FIG. 1 showing an embodiment of the present invention, a bending data editing device 1 of this embodiment includes a bending information management section 3 and a bending information editing/displaying section under the operating system of a main control section 2. A section 4, a processing information output section 5, and a bending program person output section 6 are arranged.

A data storage section 7 is arranged below the bending information management section 3. Below the bending information editing/display section 4 is the material information editing/display section.
A display section 8, a mold exchange information editing/display section 9, a bending procedure information editing/display section 1o, and a bending program editing/display section 11 are arranged. A processing information display section 12 and a processing information printing section 13 are arranged below the processing information output section 5.

A communication control section 14 is arranged below the bending program person output section 6.

The folding data editing device 1 consisting of each member 2 to 14 arranged under the operating system is an intelligent data terminal (hereinafter referred to as IDT) shown in FIG.
) 15.

The IDT 15 shown in FIG. 2 is connected to a control device such as an NC device 17 that controls each machine on the processing line, and is also connected to a local area network line (not shown).
It is also connected to other IDTs and the Intelligent Main Controller (IMC), which controls the entire processing line, and performs efficient processing while communicating data between each controller and synchronizing the connected machines with other machines. It is something.

The IDT 15 in this example includes an NC device 17 that controls a bending machine 16 and a serial communication line 1.
8.

The IDT 15 also includes a data storage section 19 for storing bending information, a floppy disk driver 20 for backing up this bending information on a floppy disk, a printer 21 for printing out machining information, and a CR
A T-display 22 is included.

FIG. 3 shows a side view of the bending machine 16.

The bending machine 16 of this example has a bunch 23 and a die 24, and the bending machine 16 has a depth axis, e.g. By moving (lowering) the punch 23 in the direction of arrow A, the workpiece W is bent into a figure 7 shape by a method called air bending.

Here, the bunch 23 is fixed to the upper part of the frame 27 via the ram 26, and the die 24 is fixed to the lower part of the frame 27 via an appropriate die holder (not shown) and an apron member 28, so that there is no space between the dies. The frame 27 bends due to the pressurizing force due to the so-called yawning phenomenon, and this is the main reason that even if the D-axis position is set once, the distance between the molds changes according to changing conditions, making it difficult to achieve high accuracy. It's difficult. This is the main reason why the D-axis position must be determined on-site.

Now, in this example, the bending data editing device 1 shown in FIG.
Accordingly, the processing information is edited in accordance with the bending program, and the edited processing information data is printed out on the printer 21 or displayed on the CRT 22 in a form that is easy for the operator to refer to.

The bending program editing/displaying unit 11 disposed below the bending information editing/displaying unit 4 is configured to, for example, process a material W1 shown in FIG. 4 to produce a product w2 shown in FIG. In the order shown by ■ to ■ in Figure 4, each flange length is 100, and each long side is followed by each short side, each with a length of 90 mm.
When bent to 0°, edit the process data as shown in FIG.

The process data in this example specifies a bending angle (90°), and the D-axis position is automatically calculated. However, in the edited NC program, the D-axis position is memorized, but it is sufficient for only the NC device 17 to be aware of this D-axis position, so it is displayed in the bending angle as shown in Figure 6, and the correction is made. An angular display is sufficient for displaying the time. In other words, if a calculation means for automatically converting an angle into a D-axis position is provided, it is arbitrary whether to display the D-axis position or the angle.

Referring again to FIG. 1, the bending procedure information editing/displaying unit 10 creates the process diagram shown in FIG. 7 based on the data on the shape of the workpiece as shown in FIG. 4 or 5 and the information shown in FIG. is automatically generated.

It is also possible to manually draw the drawings one by one using the CRT 22, but this is time consuming and difficult.

Note that in the process diagram shown in FIG. 7, the workpiece in this example has opposing surfaces, and it may be difficult to decide from which side the workpiece should be bent. As a method for removing such deviations, when cutting the material w1 shown in Fig. 4 with a laser processing machine installed in the previous process, 1.2, 3.4
It is a good idea to mark the letters with a laser. This results in
The operator can perform the folding process without hesitation by sequentially positioning the marking characters 1, 2, 3.4 between the molds.

Next, the mold exchange information editing/display section 9 displays the type of punch 23 to be used, the punch tip R, the pressure resistance value of the punch, the die 24
The model number, V width, die R, die angle, and die pressure resistance value are edited using the appropriate mold diagram. Even though it is edited, it is not necessarily necessary to input numerical values, and information may be obtained by specifying the number of a mold registered in advance and searching for the required data.

The material information editing/display section 8 displays the workpiece thickness, 5PCC,
The material and expansion force such as 5uSSAn can be edited by inputting the list.

The pigs edited by the above editing/display sections 8 to 11 are stored in the data storage section 7 formed by the bending information pig base 19 via the bending information management section 3.

Data is saved in a workpiece (one IDT15 per product).
will be centrally managed and stored by any IDT.
15, the processing information display section (CRT) 12 or processing information printing section (printer) is displayed via the processing information output section 5 or the bending program output section 6.
13 or the communication control section 14 connected to the NC device 17.

Therefore, bending information consisting of a bending program and processing information is centrally managed for each work by the bending information management section 3, and the bending program is output to the NC device 17 shown in FIG. 2, and the processing information is output to the printer. 21 or CRT 22.

The bending program input to the NC device 17 is appropriately axially corrected and the bending machine 16 is operated.

Furthermore, since the processing information can be printed out as appropriate and displayed on a CRT as shown in FIG. 7, an operator working near the NC device 17 can refer to it and perform the bending work efficiently and reliably.

In the above embodiment, an example was shown in which process data is created by the IDT 15, but it is of course possible to transfer data created by another IDT 15.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in any appropriate manner by making appropriate design changes.

[Effects of the Invention] As described above, the present invention is a folding data editing device as described in the claims, so that it is possible to easily edit processing information such as process drawings when manually editing an NC program. The folding data can be easily created and edited by the operator.
