Description

Description: TECHNICAL FIELD The present invention automatically punches a punched hole in a sheet metal material like a box body of an electric board having a hole for mounting an internal unit, further cuts and bends the sheet metal automatically. The present invention relates to a method for creating data for an NC processing machine that mechanically processes a sheet metal box.

[Background Art] For products such as conventional electric boards, the product shape of the sheet metal box is almost determined by the product type and size, so it is sufficient to prepare NC processing data for each product type and size.

At present, for example, in a development view of a sheet metal box body as shown in FIG. 2, a user who wants to process punched holes such as parts a, b, and c which are shaded with shades at any position and at any size. The demand from the side is increasing. However, conventionally, as a means for responding to the above needs, NC processing data prepared for each product size is specially processed by the user, and the product is manually modified to make a product.
It took a lot of work.

In addition, because of manual calculation, there were often mistakes in the processing position, shape, etc., and reliability was low.

[Object of the Invention] The present invention has been made in view of the above problems, and an object of the present invention is to automatically obtain data for an NC processing machine of a single sheet metal box body corresponding to a user's request. In order to reduce the number of man-hours for creating NC data and improve the reliability of processing of a sheet metal box body, it is possible to provide a method of creating data for a sheet metal box body NC processing machine.

DISCLOSURE OF THE INVENTION The present invention pre-registers standard punching NC data for standard punching of a box determined by a catalog-based product size of the sheet metal box, and inputs the first specification of the sheet box. Based on the above, the cutting processing NC data and bending processing NC data of the sheet metal material are created, and the cutting processing NC data of the sheet metal box is created based on the second specification input which is the special specification of the sheet metal box. , The standard punching NC data, the special punching NC data, and the punching NC data of the sheet metal box from the first specification input of the sheet metal box, It is characterized in that NC data composed of machining NC data, cutting NC data and bending NC data is created, and the present invention will be described below with reference to the processing flowchart of FIG.

In Fig. 1, the step of is a step for automatically designing a sheet metal box, and in this step, a special specification code (here, called a drawing number is referred to as the user's box order based on the input of the special specification corresponding to the second specification). A unique code is assigned to each case), and the machining position information and shape information of the special specifications are output to the file A. At the same time, based on the above-mentioned first specification input, the drawing number, product size information,
Nesting information (information about which part of the material to make which box part) is output to the file B.

In the step, the NC data of the special specification for punching is created based on the special processing position and shape information registered in the file A, and the drawing number data in the file A is added and output to the data file C. Here, the special specification NC data is the processing data determined by the user's special specifications when processing the parts A, B and C indicated by the diagonal lines in FIG. The master file D is a file in which the product size of the box based on the catalog is registered. In step, the product size data of the master file D is read and the standard NC data (processing according to the product size of the box is performed. (The position and shape of which are determined) and the product size data of the master file D are added and output to the data file E. The data of this data file E is data created or re-registered when the product design is changed, and normally the data as registered is used.
Here, the turret punch standard NC processing will be described with reference to FIG. 2, which corresponds to the notch portions a to d and the holes 1 to 5 in FIG.

In the step, the cutting special NC data is searched from the data file C using the drawing number data of the file B as a key, and the cutting standard NC data is searched from the data file E using the product size information of the file B as a key. These data are subjected to coordinate conversion based on the nesting information of the file B, and then combined to create a file F of the punched data of the box body, which is sent to the punching machine in a step to produce the product G.

Referring to FIG. 2, the holes 1 to 5 and the cutout portions a to d are registered as turret punch standard NC data, and the parts a, b, and c are registered as special specification NC data. , These are combined to make a box part.

Next, in a step, a file H of cutting NC data is created from the product size of the file B and nesting information, and this cutting NC data is sent to a cutting machine in a step to cut and create a product I from the punched product G. .

Further, in a next step, a file J of box bending NC data is created from the product size information of the file B, and this box bending NC data is sent to a bending machine in a step to bend the cut product I. Then, the product K is created.

[Effects of the Invention] The present invention pre-registers standard punching NC data for standard punching of a box determined by the catalog-based product size of the sheet metal box, and inputs the first specification of the sheet box. Based on the above, the cutting processing NC data and bending processing NC data of the sheet metal material are created, and the cutting processing NC data of the sheet metal box is created based on the second specification input which is the special specification of the sheet metal box. , The standard punching NC data, the special punching NC data, and the punching NC data of the sheet metal box from the first specification input of the sheet metal box, Since NC data consisting of machining NC data, cutting NC data and bending NC data is created,
The punching NC data created based on the special specification of the second specification input is added to the standard punching NC data and the first specification input, and the NC data according to the special specification is added. Can be used without adding NC data in other processing, since it is only NC data for some processing (punching processing), so it is possible to easily create NC data. There is an effect that the number of preparation steps can be reduced, errors during data preparation can be eliminated, and the reliability of sheet metal box processing can be improved.
