- the present invention relates to a method for defining a hole position of a punch mounting part in a progressive die design.
- punch and die have a relationship between male and female, it is usually better to define one shape, and to obtain the other shape by performing offset processing. It is.
- punch-shaped machining data is created after creating die-shaped machining data.
- punch-shaped machining data is left in a die-shaped layout. , But not just one material strength. They are collected and punched so that a punch is obtained and the processing is efficient.
- Fig. 7 (a) shows the position of the die shape
- Fig. 7 (b) shows the layout of the punch shapes PC1 to PC3 in the punch material WK.
- the punch PCH is usually attached to the predetermined plate PLT by the bolt BLT. .
- the bolts for tightening the plates, the holes for the pins, etc. are defined and the holes are also defined.
- H Parts (bolts) for attaching PCH to the plate PLT Define the hole HL (Fig. 8) position of the BLT. Then, the hole position in the plate PLT of the bolt BLT for mounting the punch and the hole position of the head of the punch PCH exactly match at the time of mounting the punch.
- the die shape (punch shape) and the Since the parts holes for punch mounting are moved separately, it is necessary to calculate and input the parts hole positions separately after moving the punch shape, which makes the operation troublesome.
- the part hole HL of the plate and the part hole HL of the punch head may not match exactly.
- the purpose of the present invention is to eliminate the need to separately move the die shape (punch shape) and the punch mounting component holes, and to determine the hole positions of the punch mounting components. Is to provide a definition method
- Another object of the present invention is to provide a plate and a hole which allows the punch mounting parts on the punch head to be accurately aligned with each other.
- the purpose of the present invention is to provide a method for defining a hole position of a part for mounting an inch.
- the present invention is a method for defining a hole position of a punch mounting part in a CAD / CAM system for performing a progressive die design, wherein the punch is formed on a plate.
- the part hole position data is associated with the punch shape data and recorded in memory, and the part hole is linked with the movement of the punch shape. The position is also moved, and NC data for punching is created based on the punch shape position and hole position after the movement.

- FIGS. 4 and 5 are explanatory diagrams of part hole processing information.
- the present invention will be described with reference to FIGS. 1 to 4.
- component hole machining information corresponding to components (bolts, pins, etc.) to be attached to the plate has been registered in the large-capacity storage device 15 in advance.
- the part name of bolt BL ⁇ shown in FIG. 4 is changed to ' ⁇ 1 and the mold plates PLa to PLc (see FIG. 5) to which the part is to be attached are shown.

- Drilling tool diameter B 2 depth D 2 hole type C, center fir tool, diameter 3 depth D 3 1
- a blank layout design is performed, and then, in the strip layout design, the die shape ( (Punch shape) Deformed shapes such as DF1 to DF3 are defined at predetermined positions on the plate, and are recorded in RAMI1c as data dl to d3, respectively.
- the defined die shapes (punch shapes) DF1 to DF3 are displayed on the display screen (see FIG. 1).
- the hole machining information m1 to m3 and the hole position data ii1 to h3 of the punch mounting part are obtained by the following steps. It is stored in RAM 11 c in association with 1 to ci 3. That is,
- the processor 11a By repeating the above operation for each punch shape, the processor 11a becomes the specified punch shape d1 to (! 3 and drilling information for punch mounting parts m 1 ⁇ ! n 3 and component hole position data li 1 ⁇ ! ! 3 and are associated with each other and stored in RAM 11c.
- the punch shapes DF1 to DF3 are translated, rotated and rotated so that many punches can be obtained from one material. Copy, reverse, etc. (see Fig. 7).
- the punch-shaped (dye-shaped) movement is performed by picking the punched shape with a graphic card, and moving in parallel, rotating, and so on. 'Enter reverse, copy, or delete using the menu table's shape conversion item T12, and use the graphics cursor or keyboard. This is done by specifying the movement position of the punch shape. For the movement of the punch shape, a coordinate transformation matrix corresponding to the type of movement and the movement amount is obtained, and the coordinate transformation matrix is applied to the punch shape data di. This is done by letting
- the hole position of the pan mounting component is also moved in conjunction with the movement of the punch shape.
- the hole position of the pan mounting component is also moved in conjunction with the movement of the punch shape.
- the hole position of the component is stored in association with the punch shape data, and the punch shape is determined. Since the corresponding component hole position is also moved in conjunction with the movement, it is not necessary to move the punch shape and the hole for mounting the punch separately. In addition to the ease of operation, even if the punch shape is moved and added, the position of the part hole processed on the plate and the position of the part hole processed on the punch head are accurately determined. Can be matched.
