Field of the Invention The present invention relates to a forming punching device for forming a recess on a plate or other work material, and particularly for a work having the same shape size of the recess. The present invention relates to a forming punching device configured such that the forming process can be performed by the same forming punch even if the thickness dimensions of the forming punches are different.

For this reason, there is a drawback that two steps are required for processing and the processing time including the attachment / detachment of the workpiece 70 becomes long, and both are cutting processing,
There is a problem that chips are generated and this cutting process is complicated. On the other hand, there is a press working means as a means for punching a plate material, and this press working means has the advantage that the working time can be shortened and that the processing of punching scraps is easier than that by the cutting work. .

成形パンチによって凹部７１を成形加工するのである。The dish-shaped recess 7 is formed by the above-mentioned press working means.
When machining 1 and holes 72, it is advantageous to use a progressive die or a turret press. That is, in the first step, first, the hole 72 is punched by the hole punch,
Next, in the second step, the concave portion 71 is formed by a forming punch whose lower end portion has a truncated cone shape.

It is often used as a bolt hole for so-called countersunk bolts, and for each diameter dimension of countersunk bolts to be applied, the inner diameter d i of the hole 72,
The maximum inner diameter d o and the depth h of the recess 71 are inevitably determined.

ため，同一寸法の穴７２および凹部７１を成形する場合
においても，被加工材７０の厚さ寸法ｔが異なる毎に，
夫々異なった成形パンチを準備する必要がある。However, in the above-mentioned conventional progressive die or turret press, the concave portion 7 is used.
Since the stroke or bottom stop of the press ram for operating the forming punch for forming 1 is substantially constant, the thickness of the workpiece 70 can be reduced even when forming the hole 72 and the recess 71 of the same size. Each time the dimension t is different,
It is necessary to prepare different forming punches.

ものである。FIG. 5 shows a forming punch 74 having the same shape and dimension, and a work material 7 having different thicknesses depending on the same stroke.
It is an important section sectional explanatory view showing the mode at the time of molding 0.
In each of (a) to (c), the thickness dimension of the workpiece 70 is t.
The case of 1 to t 3 is shown. In this case, in FIG. 5B, the inner diameter d 2 and the depth h 2 of the concave portion 71 have proper dimensions.

することとなり，不都合である。In FIG. 5A, since the thickness t 1 of the workpiece 70 is smaller than the thickness t 2 of the workpiece 70 shown in FIG. 5B, the workpiece 70 is formed by the forming punch 74. The maximum inner diameter d 1 and the depth h 1 of the recess 71 are both d 1 <d
2 , h 1 <h 2 . Therefore, when a predetermined countersunk bolt is mounted, the head of the bolt comes out of the upper surface of the workpiece 70, which is inconvenient.

材７０の残余の肉厚が小さくなるという不都合がある。On the other hand, in FIG. 5 (c), the maximum inner diameter of the recess 71 is d 2 , but the depth h 3 is large, and h 3 > h
As a result of 2 , not only the head of the mounted countersunk bolt goes into the recess 71, but also the residual thickness of the workpiece 70 to be tightened becomes small.

Even when the recesses 71 having the same size are formed, when the thickness of the workpiece 70 is different, it is necessary to perform setup change including exchange of the forming punch, which lowers workability and productivity. There is a problem.

The workpiece 70 is placed on the die 2 shown in FIG. Then, when the pressure head 10 is lowered via the press ram or the operating ram of the hydraulic cylinder (neither is shown),
The respective constituent members including the stripper 4 are integrally lowered. That is, since the elastic force of the compression coil spring 18 is made larger than the elastic force of the compression coil spring 7, the compression coil spring 7 is first deformed, and the lower end surface of the stripper 4 is placed on the die 2 to be processed. The workpiece 70 is brought into contact with the surface of the workpiece 70, and the workpiece 70 is pressed and sandwiched by the stripper 4 and the die 2.

The dish-shaped recess 71 is formed. In this case, the bottom point of the forming punch 8 is the position where the punch head 11 contacts the stopper 19. Therefore, the forming stroke of the forming punch 8 can be determined by, for example, selecting the axial dimension of the stopper 19.
It is set by adjusting the distance L between the punch head 11 and the stopper 19. The axial pressure applied by the pressing member 17 can be set by adjusting the distance between the pressing head 10 and the punch head 11.

しておけばよい。After the forming process is completed, the stripper 4 moves the work piece 70 until the forming punch 8 and the work piece 70 are separated from each other.
By pressing the surface of the work piece 70, undesired jumping up of the workpiece 70 is prevented. Although the inner diameter d i of the hole 72 shown in FIG. 4 is slightly reduced due to the plastic flow associated with the forming process of the forming punch 8, the material to be processed 70 and the shape and size of the recess 71 are taken into consideration in advance. The inner diameter of the hole 72 to be provided may be large.

In the structure shown in FIG. 2A, the lower end of the forming punch 8 is formed into a truncated cone shape, and a short cylindrical body having an outer diameter d i is integrally provided therebelow. By forming in this way,
The diameter reduction of the hole 72 due to plastic flow at the time of molding can be relaxed. FIG. 2B is an example in which the lower end of the forming punch 8 is formed in a conical shape.

However, this order is reversed and the forming process is performed in the first step. Then, in the second step, the hole 72 can be drilled. In this case, FIG.
As shown in (b), in order to facilitate the plastic deformation of the workpiece 70, the die 2 may be provided with the recess 3. However, the inner diameter d of the recess 3 is the same as the hole 72 shown in FIGS.
It is preferable that the inner diameter is smaller than the inner diameter d i .
