Abstract

PURPOSE:To check easily the hole forms as well as the interference by drawing only the cross section of a specified plate among those cross sections specified by the cross section numbers. CONSTITUTION:The position of each parts hole is specified by the mold structure processing and stored in a RAM 11c. While the corresponding relation among the cross section number which specifies a prescribed cross section, a plate forming the cross section and the parts hole drawn on the cross section is stored in a large-capacity storage device 13 in the form of a data file. Then the cross section number is designated together with a plate or more. Thus the cross section of a specified plate is produced by means of the processing conditions and the position information on the parts hole formed on a specified plate among those holes corresponding to the cross section numbers. Therefore the cross section can be drawn by changing the plate constitution of the registered cross section as necessary. This facilitates the easy check of the hole forms as well as the interference.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method for drawing a cross-sectional view, and in particular, it is possible to draw a cross-sectional view of an arbitrary (one plate above) a plate on a CRT as necessary. This invention relates to a method for drawing a cross-sectional view.

<Prior Art> In a progressive die, punches are arranged at every predetermined stroke, and each time the plate material is fed progressively, punching is performed by the punches of each stage, and a desired part is obtained from the final stage.

Such a progressive die is composed of several punches and a plurality of plates. FIG. 5 is an explanatory diagram of the progressive die, including an upper die set 1, an upper backing plate 2, a punch plate 3, a stripper plate 4, a die plate 5,
It has a lower backing plate 6 and a lower die set 7, and the punch plate 3 has several punches P1 having a predetermined cross section.
, P2, P3... are fixed, and the stripper plate 4, die plate 5, lower backing plate 6, and lower die set 7 facing the punch are provided with hollow holes H1 of the same shape.
~H3 is provided. Note that the hollow hole formed in the stripper plate 4 is for passing a punch through, and the other hollow holes are for receiving the punch during punching and for dropping the punched plate material downward.

Each plate has bolt insertion holes B11 and B12.

PI, LP2, etc. are provided as appropriate. In addition, the bolts are used to fix adjacent plates, and the dowel pins are used to prevent misalignment between the plates even when the bolts are tightened. The suspension bolt is attached to a urethane spring and suspends the stripper plate 4 with elasticity, and it contracts during punching and expands as the punch plate 3 rises after punching is completed, pushing down the plate 8 and causing the plate to rise together with the punch plate 3. The lifter bin is used to hold the plate material 8 at a predetermined height above the surface of the gouging plate 5.

As understood from the above configuration, in order to produce a progressive die, (al each punch (tool) PI, P2.P3・-・+7)
In addition to determining the shape and creating NC data for punching, you also have to create the NC data for hole punching (designing a plate with various holes and creating a mold concept).

By the way, in order to create the NC data for hole machining in (b), it is necessary to input the hole position in each plate and the machining conditions for the hole. Note that the machining conditions indicate what kind of tool (type and diameter of the tool) and what depth of machining is to be performed. For this reason, (1) the first correspondence between various plate holes formed in each plate and the processing conditions of the plate holes is registered in advance, and (2) holes spanning two or more plates or one plate When each hole formed only on the plate is called a machined hole (a machined hole is a collection of plate holes), a second correspondence relationship between the machined hole and the plate hole is registered, and (3) machined hole name. The holes to be formed in each plate of the mold plate are specified by inputting the position of the machined hole.

FIG. 6 is an explanatory diagram of the first and second correspondence relationships.

Now, the name of the machined hole is Hl, and each plate PLa %
Play 1 of P L c - Hole names are α, β, γ, plate hole 〇 is drilled to depth DI with a tool of diameter A1, then deepened with a tool of diameter B1, and drilled in step 2. countersunk to a depth of D13 using a tool of diameter C, and finally countersunk to a depth of D13 using a tool of diameter E1.
The plate hole β is tapped to a depth of D2. with a tool having a diameter of A2. The plate hole γ is obtained by performing center milling to a depth of D2□ with a tool of diameter B2, and then center milling to a depth of D31 with a tool of diameter A3. If it is obtained by drilling to a depth of D3□ with a tool, and finally drilling to a depth of D3 with a tool of diameter E3, and tapping 3, the first correspondence is α, center mini tool, diameter A1, depth Dl.

Drilling tool, diameter B1, depth D12 Countersink countersunk machining diameter C1 depth D Tapping tool, diameter E1, depth D14 β, center mini tool, diameter A2, depth D2゜Drilling tool, diameter B2, depth D2□ γ, center mini tool, diameter A3, depth D31 drilling tool, 8 diameters, depth D32 tapping tool, diameter E3, depth D33, and the second correspondence is Hl, α, β, γ; Become.

Now, once the hole position and hole machining conditions are specified, the plan view of the plate specified by the request or the plan view of each plate are superimposed and drawn on the display screen, or drafted, or output by other methods. It is now possible to do so. By drawing this plan view, it is possible to check whether the hole positions and hole machining conditions have been correctly inputted to a considerable extent.

However, only by drawing a plan view, it is not possible to check for interference between parts (hole shapes) that do not appear in the plan view.

For this reason, the applicant of the present application has proposed a method for drawing a cross-sectional view of the plate in addition to the plan view so that parts that do not appear in the plan view can be seen to check for hole interference. Further, according to this cross-sectional diagram drawing method, the created cross-sectional diagrams are registered with numbers, and if necessary, it is possible to input the number of a predetermined cross-sectional diagram and draw that cross-sectional diagram. .

<Problems to be Solved by the Invention> By the way, when drawing a registered cross-sectional view by inputting a cross-sectional view number, if you want to draw a cross-sectional view by changing the plate configuration of the registered cross-sectional view. There is. For example, you may want to draw a cross-sectional view of some of the upper or lower plates by changing the plate designation of a cross-sectional view created with all plates to upper plate or lower plate. Furthermore, there are cases where it is desired to draw only the cross-sectional view of the specified plate by specifying the plate number. This is because when checking the hole shape or interference, there are cases where it is desired to see only the cross-sectional view of a predetermined plate, and in such a case, it becomes difficult to see if cross-sectional views of other plates are displayed at the same time. In addition, there are cases where it is desired to consider a cross-sectional view of a certain plate number and then view another cross-sectional view or the entire cross-sectional view.

That is, although it would be convenient if a cross-sectional view could be drawn by changing the plate configuration as needed, it has not been possible to satisfy this requirement in the past.

From the foregoing, it is an object of the present invention to provide a cross-sectional view drawing method that can draw a registered cross-sectional view by changing the plate configuration of the registered cross-sectional view as necessary.
