The shape of the support 65 for supporting the advance / retreat means 66 is arbitrary as long as it supports the advance / retreat means 66 and preferably a flat surface 67B below the advance / retreat member 70. In addition, the spacer 7 is attached to the upper surface of the lower receiving body 6 and, for example, a support 65 is attached to the mounting member 47A so that the advance / retreat member 70 can move forward and backward between the spacer 7 and the upper receiving body 5. You may.

The caulking receiver 4 with the spacer 7 interposed between the upper and lower receiving main bodies 5 and 6 is, as shown in FIG.
Are inserted between the upper and lower mating flanges FU, FD of the two shaped steel materials A, A set in the above. At this time, the upper end of the swaging receiver 4, in this example, between the upper surface of the upper die 39A and the inner surface of the upper mating flange FU, and the lower end of the swaging receiver 4, in this example, the lower surface of the lower die 39B. A gap G is provided between the lower mating flange FD and the inner surface.

Further, as shown in FIG. 6, the advancing / retreating member 70 is advanced, and the upper end and the lower end of the caulking receiver 4 are brought into contact with the inner surfaces of the upper and lower mating flanges FU, FD. At this time, the gap G can be reduced to, for example, about 5 mm by the spacer 7, so that the moving dimension of the caulking receiver 4 can be suppressed to a necessary minimum, and simplification and caulking of the adjusting means 9 can be achieved. Can be simplified, production speed can be increased, and productivity can be improved.

In this embodiment, the upper and lower flat surfaces 67A and 67B receive the flat surfaces 61 and 51B of the caulking receiver 4 when the advancing and retreating member 70 advances. , And the strength of the swaging receiver 4 can be increased. In addition, the height h between the upper and lower flat surfaces 67A and 67B is set so that the gap G is absorbed and the swaging receiver 4 is in contact with the inner surfaces of the upper and lower mating flanges FU and FD. Also, the caulking support 4 and the upper and lower mating flanges F
The height h may be set so that a minute gap is formed between U and FD.
The height h may be set so that one or both of the U and the FD are slightly elastically deformed and the caulking receiver 4 comes into contact with the inner surface thereof.

Further, by preparing a plurality of spacers 7 having different heights, the upper and lower receiving bodies 5 and 6 can be used as they are, and the distance between the upper and lower mating flanges FU and FD can be varied. Since the spacers 7 can cope with the caulking of the shaped steel materials A, A and the spacers 7 do not have any dies or the like and do not require precision, the spacers 7 can be automatically attached and detached and replaced.
It is not necessary to replace 9A and 39B.

As shown in FIG. 7, the upper caulking tool 2 is lowered to contact the outer surface of the upper mating flange FU.
The apparatus main body 19 is lifted by the reaction force from the worktable E, and the lower caulking tool 3 is brought into contact with the outer surface of the lower mating flange FD.
U and FD are caulked at the same time.

The spacer 7 of the caulking receiver 4
As shown in FIG. 8, the spacer is divided into a plurality of, for example, two spacer pieces 11A and 11B, and the adjusting means 9 is provided with one receiving body, for example, the lower end of the lower receiving body 6, and The height H sandwiching the upper end of the spacer piece 11B adjacent to the receiving body 6 may be adjusted.

In this example, a flat surface 71 similar to the flat surface 61 and the inclined surface 62 is provided on the lower surface of the spacer piece 11B.
An inclined surface 72 is provided to guide the advance and retreat of the advance and retreat member 70.

The attachment and replacement of the spacer 7 can be performed as described above. In this example, the spacer pieces 11A having different heights are prepared, and the spacer pieces 11A adjust the height of the caulking receiver 4. Since only the function is required, the processing (formation of the inclined surface) for the reciprocating member 70 only needs to be performed on one spacer piece 11B, and there is an advantage that the structure is rational.

Further, even if the spacer piece 11A is replaced, the portion where the adjusting means 9 advances and retreats can be limited to the spacer piece 11B and the lower receiving body 6 which can be continuously used. This can reduce the risk that the reciprocation operation will be out of order.

As shown in FIG. 9, by forming the upper and lower surfaces of the advancing / retreating member 70 only from the upper and lower tapered surfaces 73A and 73B, the range for absorbing the gap G can be increased. Further, as shown in FIG. 10, only one surface may be a tapered surface 74 and the other surface may be a flat surface 75.

The pressing device 1 for caulking includes a spacer 7
Without intervening, the two receiver main bodies 5 and 6 can be combined and used.

[0040]

As described above, the caulking press device according to the present invention is characterized in that the caulking receiver inserted between the inner surfaces of the mating flanges includes two main body members which contact the upper and lower inner surfaces of the mating flange during caulking; Since it is composed of a spacer interposed between them, the height of the spacer is appropriately selected and mounted between the two receiving bodies, so that it can be used for caulking of shaped steel materials of various dimensions, and at the time of caulking, the fitting flange is formed. The operating dimension for moving the caulking support so as to contact the upper and lower inner surfaces can be minimized, and the productivity can be improved by simplifying the apparatus and increasing the production speed.

Also, since the height of the caulking holder can be adjusted by a spacer that does not require high precision, the spacer can be easily attached and replaced, and the replacement of a die or the like is not required.

[0042] In the invention according to claim 2, the caulking receiver has an adjusting means for adjusting the height in the direction between the mating flanges, and the spacer is divided into a plurality of spacer pieces. The means for adjusting the height between the one receiving body and the spacer piece adjacent to the receiving body may be adjusted even if a spacer piece other than the spacer piece adjacent to the receiving body is replaced. The structure for continuously using the portion for adjusting the height of the caulking holder can be used, so that the risk of the operation mechanism of the adjusting means being out of order can be reduced.

Further, the spacer pieces other than the spacer pieces adjacent to the receiving body need only have the function of adjusting the height of the caulking receiving means, so that there is no need to perform processing according to the adjusting means. The structure can be rationalized.
