Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a method for editing work data of a press brake.

(Conventional technology) In recent years, automation of press brakes for bending flat plate-shaped workpieces has progressed, and the workpiece can be bent after inputting material property data such as workpiece material, tensile strength, plate thickness, and elongation correction value. Now, when a shape is input, a series of workpiece data is automatically generated, including the bending process, the bending shape of each process, and machine control data such as the back gauge position and depth axis position for each process.

To give an example, the bending process and the bending shape of each process are developed by developing the product shape to a flat plate, and setting the bending order by reversing the development order, and the shape in that process and the control data for creating that shape. is automatically generated. Furthermore, when creating these workpiece data, molds are automatically selected including a mold interference check. Therefore, if the final created workpiece data is used, the mold will not interfere with the machine, and semi-automatic or fully automatic bending can be performed simply by providing a workpiece supply service.

However, even with this automatically generated work data, since the press brake is an extremely delicate machine,
It is normal that some adjustment is required to match the actual machine.

Therefore, conventionally, while employing the automatic generation method of workpiece data as described above, various workpieces have been created over time while making minute adjustments each time.

(Problem to be Solved by the Invention) However, in the conventional method of editing workpiece data of a press brake as described above, workpiece data is created each time a workpiece is changed. There was a problem in that the workpiece data was not reflected in subsequent machining, making the work difficult.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for editing work data of a press brake, which allows work data of an already machined work to be reflected in subsequent processing, and work data can be created easily and quickly.

[Structure 1 of the Invention (Means for Solving the Problems) The present invention for solving the above problems includes workpiece shape data in each bending process of a press brake, control data for controlling each bending process, and workpiece product shape data. In a method of editing a series of workpiece data for workpiece machining, etc., the workpiece data that was actually bent is stored and saved in a storage device arranged in relation to the bending control device, and new workpiece data is created. When you want to edit, search for workpiece product shape data for the workpiece data stored in the storage device, display a list of the shapes, and edit part of the workpiece data for the workpiece selected from the displayed list of shapes. The present invention is characterized in that work data for a new work is edited by modifying the data.

(Function) In the press brake workpiece data editing method of the present invention, workpiece data for already machined workpieces is memorized and saved, a list of workpiece shapes of already machined workpieces is displayed, and a list of shapes is selected from the displayed list of shapes. Easy by selecting a workpiece with the same pattern or similar shape as the new workpiece and modifying part of the workpiece data for the selected workpiece.

To quickly edit work data for a new work.

(Example) Hereinafter, examples of the present invention will be described in detail by giving an example of application to an actual press brake.

The automatic programming device 8 is configured to operate the control device 1 based on the specifications of the man-machine interface 6.
It generates O program data and outputs it to the control device w11.

Work data storage device i! 9 is work data edited by the man-machine interface 6 and executed by the control device 1, excluding those with the same content, such as work number, work name, product shape 1 bending order data, process shape data, and control data. It is stored sequentially as follows.

In FIG. 1, a work data editing device mainly composed of the man-machine interface 6 includes a work data editing section 10 interposed between the control II device 1 and the work data storage device 9, and a display command section. 11, a work shape display section 12, and a similar work selection section 13.

The work data storage bag @9 stores a large number of classified work data regarding already processed workpieces.

The display command unit 11 commands to display a list of workpiece shapes for already machined workpieces in response to key operations on the MDi 6B when editing workpiece data for a new workpiece.

The workpiece shape display section 12 displays a list of workpiece shapes as shown in FIG. 3 on the CRTeA in response to commands from the display command section 11.

In the display of FIG. 3, the shape of each workpiece number 001.002... is displayed on the screen of the CRT 6A. This display displays the product shape data of the workpiece data. The list of workpiece shapes and shapes may be displayed not in order of workpiece numbers but in order of storage order, starting with new data. Further, the information may be displayed according to the classification according to the user. Furthermore, if the information does not fit on the screen, a plurality of images may be displayed by turning the page.
