BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a standard assembly drawing creation system for creating standard assembly drawings used in mold design using CAD.

0002

[Prior Art] Conventionally, in mold design using CAD, multiple patterns of standard assembly drawings consisting of a standard assembly plan view and an assembly cross-sectional view are registered in advance in a common library, and when creating the assembly drawings, as needed. The design was carried out using the registered standard assembly drawings. FIG. 6 shows the procedure for designing a mold using such a standard assembly drawing.

As shown in the figure, first, if a standard assembly drawing of the same size as the mold to be designed is registered in the common library, call the standard assembly drawing of the same size from the common library, and then , if a standard assembly drawing of the same size is not registered, a standard assembly drawing of the size most similar to it is called from the common library (step a1). In the latter case, after calling the standard assembly drawing,
Modifications are made to this so that the desired size and parts display position are achieved (step a2). This modification requires CAD
Manual work from the terminal is required. Once the usable standard assembly drawings have been prepared in this way, design such as creating assembly drawings is started based on them (step a3).

[Problem to be Solved by the Invention] In conventional mold design using standard assembly drawings, if a standard assembly drawing of a desired size is not registered in the common library, it is necessary to create a standard assembly drawing of an approximate size as described above. I called up the assembly drawing and made some modifications to get it to the desired size. However, since such corrections must be made manually, it takes a lot of time, and since it cannot be applied to all sizes, there is a problem that the scope of use is extremely limited.

SUMMARY OF THE INVENTION An object of the present invention is to enable standard assembly drawings of a desired size to be easily created without performing troublesome manual correction work.

[0006]

[Means for Solving the Problems] FIG. 1 shows a diagram of the basic configuration of the present invention. As shown in the figure, the standard assembly drawing creation system of the present invention includes at least parameter storage means 1;
The apparatus includes an input means 2 and a standard assembly drawing creation means 3.

[0007] The parameter storage means 1 is a part that converts data regarding standard assembly figures into size parameters and stores them, and is made up of, for example, a normal storage device. Size parameters include, for example, the length, width, thickness, etc. of each plate that constitutes a standard assembly figure.

The input means 2 is a part for specifying a size parameter according to a desired standard assembly drawing and inputting a numerical value indicating a specific size into the specified parameter, and is composed of, for example, a keyboard, a touch pen, etc. .

The standard assembly drawing creation means 3 is a part that creates a specific standard assembly drawing from the parameters stored in the parameter storage means 1 according to the numerical values input by the input means 2, and includes, for example, a CPU. It consists of a calculation section, etc.

0010

[Operation] By specifying each size parameter and inputting a numerical value using the input means 2, a standard assembly drawing of a desired size corresponding to the numerical value is created by the standard assembly drawing creating means 3. Therefore, a standard assembly drawing of any size can be obtained without the conventional modification work of the standard assembly drawing, making it possible to save labor in design. Furthermore, since it can be applied to any size, the range of use is expanded compared to conventional methods.

[0011]

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 2 shows a system configuration of an embodiment of the present invention.

In the figure, a CPU 11 is a central processing unit that operates according to a microprogram stored in a built-in ROM (read-only memory), although not specifically shown, and controls the entire system. In addition, data stored in the storage device 14 and the keyboard 1, which will be described later, are also included.
A standard assembly drawing is created based on the data input from 2.

The keyboard 12 includes a plurality of keys for inputting various data and operation commands. Through key operations on the keyboard 12, each size parameter is designated, and specific dimensions (numerical values) corresponding to the desired size are input for the designated parameters.

The display 13 is a display unit that displays input data from the keyboard 12 and standard assembly drawings (lower model plan view, upper model plan view, and sectional view) created by the CPU 11.

The storage device 14 is composed of a RAM disk, a register, a bitmap memory, etc., and stores standard assembly figures converted into size parameters in advance. Also, various data are written and read by the CPU 11. It will be done. As a size parameter, for example, Fig. 5
There are a to k as shown in . a is the plan view plate width, b
is the plan view plate length, c is the upper die set thickness, d is the upper backing plate thickness, e is the punch plate thickness, f is the body plate thickness, g is the stripper plate thickness, h is the product plate thickness, i is the die plate The thickness, j is the lower backing plate thickness, and k is the lower die set thickness. The storage device 14 does not directly store standard assembly drawings of multiple patterns as in the past, but stores size parameters a to k as shown in FIG.
It stores only.

A design procedure using the system of this embodiment having the above configuration will be explained based on FIG. 3. First, each size parameter as shown in FIG. 5 is specified using the keyboard 12, and specific dimensions (numeric values) corresponding to each size of the desired standard assembly drawing are input corresponding to each size parameter (step b1).

Thereafter, by starting the standard assembly drawing creation program, the standard assembly drawing (lower die plane , upper mold plan view, and cross-sectional view) are automatically created (step b2). The processing operation at that time will be explained based on FIG. 4.

First, input each parameter (step c1
), then a pattern unit determination process is performed (step c2). This process is performed for various parts (e.g. bolts, knocks, springs, guide pins, guide bushes, etc.) according to the plate width and plate length obtained based on the parameter input (see parameters a and b shown in Figure 5). This is a process of determining the arrangement pattern of , and one pattern is selected from a plurality of preset patterns.

Thereafter, a process for creating a bottom mold plan view, which is one of the standard assembly drawings, is performed (step c3). In this process, an outer frame is first created based on the plate length and plate width, and then components are arranged within the plate based on the plate size and the arrangement pattern of the components. continue,
The upper mold plan view is created in the same way as the lower mold plan view (step c4).

Next, structure determination processing is performed (step c
5). Mold forming includes punching and bending, so
It is determined whether the desired mold has a structure for punching (punching structure) or a structure for bending (bending structure). This determination can be made by inputting a structural parameter for specifying whether the desired mold has a punched structure or a bent structure when inputting the size parameters.

Here, if a punched structure is specified, a cutout structure sectional view is created (step c6).
), on the other hand, if a bending structure is specified, a bending structure sectional view is created (step c7). In these processes, the plate outer frame is created using the plate width and thickness of each part obtained based on parameter input, the placement coordinates of the parts are determined, and then the plate frame is created based on the placement coordinates and length specifications of this part. A cross-sectional view is created by arranging the parts.

Through the above processing, a standard assembly drawing consisting of a lower mold plan view, an upper mold plan view, and a cross-sectional view (cutting structure cross-sectional view or bent structure cross-sectional view) is automatically created, and the display 1
3.

Once the ready-to-use standard assembly drawing is prepared on the display 13 in this way, the design of the mold is started using this standard assembly drawing (step b3 in FIG. 3).
). Therefore, according to this embodiment, by simply inputting parameters, a standard assembly drawing of a desired size that can be used immediately can be created in a short time without having to perform the troublesome modification work of standard assembly drawings as in the past. Therefore, significant labor savings in mold design can be achieved. Moreover, since it can be applied to any size that is impossible with conventional correction work, the scope of use can be significantly expanded compared to conventional methods.

In the above embodiment, the CPU 11, the keyboard 12, the display 13, and the storage device 14 constitute one system. It is also possible to configure a terminal device connected to the host computer system.

Further, instead of the keyboard 12, other input devices such as a mouse or a touch pen may be used. In this case, a data menu, command menu, etc. for input are displayed on the display screen, and input is performed by selecting data or commands from the displayed menu with a mouse or a touch pen.

Further, the parameters shown in FIG. 5 are just examples, and the present invention is not limited thereto, and various parameters can be used depending on the structure of the mold and the like. In addition, the standard assembly drawing creation process shown in FIG. 4 is just one example, and various processes can be adopted as long as they are capable of creating standard assembly drawings based on parameters.

[0027]

[Effects of the Invention] According to the present invention, a standard assembly drawing of any size can be easily obtained by simply inputting parameters, thereby eliminating the need for troublesome correction work as in the past, and thus significantly reducing the design. Labor saving can be achieved. Furthermore, since it can be applied to any size, the range of use can be significantly expanded compared to conventional methods.
