When the corner of the tip is pressed from one side surface of the molding flat member by an extrusion punch formed into a spherical shape 210, most of the material (wall portion) of the molding flat member is extruded to the side by the extrusion punch to form a shaft. There is little volume to work for,

When the flat plate member is pressed from one side with an extrusion punch formed with a flat or gentle spherical concave surface, the acting force pressed in the direction of the forming hole is strong, and the molding extruded in the direction of the forming hole.

φ１は形成する突起軸４の直径φ２に対して 1.5〜 2.5
倍の直径となるようにしてある。As shown in FIG. 3, the relationship between the extrusion punch 4, the flat plate member 2, and the forming hole 5 formed in the die 6 forming the projection shaft 3 and the diameter and length of the projection shaft 3 formed by these are shown in FIG. Has become. That is, the upper end (tip) surface 4a of the extrusion punch 4 is formed flat, and the corner of the peripheral edge is 0.1
The diameter φ1 of the extrusion punch 4 is 1.5 to 2.5 times the diameter φ2 of the projection shaft 4 to be formed.
The diameter is doubled.

することができないためである。The reason why the diameter φ1 of the extrusion punch 4 is set to 1.5 to 2.5 times the diameter φ2 of the projection shaft 3 is that, when the diameter is 1.5 times or less, the extrusion punch 4 is operated when the extrusion punch 4 is operated. Flat plate member 2 escaping around punch 4
This is because the thickness of the plate member 2 is large and the volume of the flat plate member 2 supplied to the molding hole 5 is small, so that the height of the projection shaft 3 cannot be formed to a desired height.

起軸３の強度が充分に保てないためである。On the contrary, the diameter φ1 of the extrusion punch 4 is
If the diameter of the projection shaft 3 is 2.5 times or more of the diameter φ2 of the projection shaft 3, the pressing force of the extrusion punch 4 becomes unnecessarily large, and not only a large driving device is required, but also the projection shaft 3 and the flat plate member 2 This is because the thickness of the connecting portion with and becomes thin, and the strength of the protrusion shaft 3 cannot be sufficiently maintained.

起軸３の体積に対して 4.0倍以上では動力損失が大きく
なるためである。The stroke S of the pushing punch 4 for pressing the flat plate member 2 is such that the pressed volume of the flat plate member 2 is 1.5 to 4.0 times the volume of the projection shaft 3. This is the stroke S of the extrusion punch 4.
However, when the pressed volume of the flat plate member 2 is 1.5 times or less the volume of the projection shaft 3, the volume of the flat plate member 2 supplied to the forming hole 5 is small and the height of the projection shaft 3 is reduced. The extrusion punch 4 cannot be formed to the desired height.
This is because the power loss increases if the stroke S of the flat plate member 2 is 4.0 times or more the volume of the projection shaft 3 when the stroke S is pressed.

ある。The stroke S of the pushing punch 4 and
The relationship with the diameter of the extruding punch 4 is relatively inversely proportional. In this example, first, after the diameter φ1 of the extruding punch 4 is set, the stroke S is determined. May of course be reversed.

題が生じるためである。On the other hand, the forming hole 5 in the die 6 comprises a straight portion 5a formed on the extrusion punch 4 side and a tapered portion 5b formed divergently from the straight portion 5a.
The length L1 of the straight portion 5a is longer than a half of the height L3 of the projection shaft 3 to be implanted and shorter than the height L3 of the projection shaft 3. The length L1 of the straight portion 5a is longer than the half of the height L3 of the projection shaft 3 to be planted as described above.
Is shorter than the height L3 of the protruding shaft 3 when the formed protruding shaft 3 is
If the length L1 of the straight portion 5a is shorter than half of the height L3 of the projection shaft 3, the projection shaft 3 formed will attach the straight portion 5a. This is because there is a problem in that when it comes out, it is easy to swell and it is difficult to pull out.

First, after a die 6 having an extrusion punch 4 and a forming hole 5 is mounted on a pressing device (not shown), a portion where the projection shaft 3 of the flat plate member 2 is formed between the extrusion punch 4 and the forming hole 5 is formed. The flat plate member 2 is supplied so as to be positioned.

At this time, the acting force pressed in the direction of the forming hole is strong, and the flat plate member 2 extruded in the direction of the forming hole is formed axially in the forming hole 5. At this time, the volume of the meat of the flat plate member 2 pressed by the extrusion punch 4 is supplied in an amount sufficient to form the projection shaft 3, so that the projection shaft 3 longer than the plate thickness of the flat plate member 2 can be reliably formed. Can be done.

産することができると言う利点がある。As described above, according to the present invention, a flat plate member is pressed from one side thereof by an extrusion punch formed with a flat or gentle spherical concave surface, and is pressed in the direction of the forming hole. The acting force is strong, and the molding flat member extruded in the direction of the molding hole can be axially molded by the molding hole. Thus, there is an advantage that the production can be easily performed in a short time by the press device.
