Abstract

PROBLEM TO BE SOLVED: To shorten the stroke and to firmly and uniformly execute caulking by attaching a caulking receive body on the top end of a piston rod and having a caulking punch to oppose to the caulking receive body on the opposite face of the top end of an arm moving as one body with a cylinder body. SOLUTION: A caulking receive body 13 of the top end of a piston rod 12 and a caulking punch 20 of the top end of an arm 18 made by one body with a cylinder body 11 are approached or separated mutually at the same time by supplying or discharging an oil to a hydraulic cylinder 10. Therefore, the caulking punch 20 with a short stroke can be used for caulking, together with the caulking receive body 13 of mutually approaching, firm and uniform caulking can be executed. Especially, because the width dimension of adding a vertical part 19 on the top end of the arm 18 and the caulking punch 20 can be made possibly small, this is used profitably even for caulking a work having a narrow caulking part and caulking can be executed also in a small space.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for joining two members by caulking, and has a particularly simple structure.
The present invention relates to a swaging apparatus capable of performing strong and uniform swaging.

[0002]

2. Description of the Related Art Conventionally, a set of punches and a receiving material facing the punches have been used for crimping.
For example, as shown in FIG. 7A, a punch P and a receiving material U are opposed to each other, and a work W composed of a profile 200 and a plate 210 is inserted therebetween. The profile 200 has a concave groove 202 which opens downward at the center of the end face 201 along the longitudinal direction.
A crimping piece 204 is provided on one side of the concave groove 202 and a caulking receiving piece 206 is provided on the other side, and a caulking receiving groove 208 is provided on the entire length of the caulking receiving piece 206 on the side of the concave groove 202.
Then, with respect to the workpiece W in which the plate member 210 is inserted into the concave groove 202, the receiving material U is brought into contact with the outer surface of the caulking receiving piece 206 of the shaped material 200, and the punch P is moved from the outer surface of the caulking piece 202 in the F direction. When driven in, as shown in FIG.
In FIG. 4, a crimping convex portion 205 is formed in the thickness direction following the outer shape of the punch P, and a thin crimping bent portion 212 is formed on the adjacent plate member 210. This bend 21
No. 2 is inserted into the crimp receiving groove 208 at its leading end.
To perform such caulking, a pair of punches P and a receiving material U are prepared, and the punches P are driven while supporting the receiving material U. The driving of the punch P requires a hammer driving stroke behind it. In addition, when the driving is not uniform, the shape and strength of the swaged portion also vary. Further, continuous caulking requires labor. Further, the rear end of the punch P can be fixed to the ram of the hydraulic press, but its use may be restricted depending on the cross-sectional shape of the profile 200.

On the other hand, as an apparatus for continuously and uniformly caulking, as shown in FIG. 7B, a set of caulking rolls 222 is used.
The apparatus 220 using the receiving roll 230 is also used. The caulking roll 222 has a large number of punches 226 having a pointed conical shape projecting radially on a circumferential surface 224 thereof, and is rotatably supported by a rotating shaft (not shown). The same work W as described above is placed on a receiving roll 230, and the caulking roll 222 is lowered from above, and the lowermost punch 226 is pressed against the caulking piece 204 of the profile 200. Then, the same crimping convex portion 205 and crimping bent portion 212 are formed as described above. Furthermore, caulking roll 22
2 and the receiving roll 230 are rotated to form the caulking continuously at equal intervals along the longitudinal direction of the work W. However, since the caulking device 220 has the pair of rolls 222 and 230 facing each other, it always requires a necessary space, and is difficult to use in a narrow place. Further, since a rotating means and a lifting mechanism of the caulking roll 222 and a parallel moving mechanism of the caulking roll 222 and the receiving roll 230 are required, there is a problem that a complicated mechanism and high cost are required.

A caulking receiver 13 is attached to the distal end side of the piston rod 12 of the hydraulic cylinder 10 by screw connection so as to be adjustable. At the distal end of the cylinder body 11, an arm 18 having a base end 17 screwed to the peripheral surface thereof and fixed thereto extends parallel to the rod 12. A caulking punch 20 is attached to the vertical portion 19 at the tip of the arm 18 so as to be spaced apart from the caulking receiver 13.
Further, a guide 22 fixed to a lower portion of the arm 18 is provided.
Is slidably supported on a guide rail 3 provided on the upper surface of the gantry 2 and also supports a hydraulic cylinder 10. The guide 22 is fixed to the bottom surface of the cylinder body 11, and the arm 18 is connected via the cylinder body 11.
May be supported.

In the main body 11 of the hydraulic cylinder 10,
A piston 14 fixed to the piston rod 12 is slidably housed therein, and into each of the cylinder chambers 15 on both sides defined by the piston 14, oil compressed through a pair of ports 16 attached to the cylinder body 11. Is supplied by a hydraulic pump (not shown) or the like. Therefore, FIG.
In (B), when oil is supplied to the right cylinder chamber 15 and oil is discharged from the left cylinder chamber 15, the piston 14
Moves to the left, and the swaged receptacle 13 at the tip also moves to the left along with the piston rod 12. At the same time by the ingress and egress of oil,
The cylinder body 11 moves to the right while compressing the coil spring 8, and together with the arm 18 integrated with the coil spring 8, the crimping punch 20 at the tip also moves to the right and approaches the caulking receiver 13 (FIG. C)). Incidentally, 16a in the figure is
A stopper that regulates the sliding amount of the piston 14 and is provided near each of the entrances 16.

On the other hand, as shown in FIG. 2A, the work W is composed of a shape member 30 and a plate member 37. The shape member 30 has a concave groove 32 facing upward at a corner of an end portion 31 having an L-shaped cross section along the longitudinal direction, and a crimp piece 33 and a crimp receiving piece 34 on both sides thereof. A caulking receiving groove 35 is provided in the middle of the caulking receiving piece 34 on the concave groove 32 side. The profile 30 is made of an extruded profile made of an aluminum alloy, and has each of the above-described elements over its entire length in the longitudinal direction.
