Has been.
[0024]
Next, the jig assisting device 30 used when the thin plate material 22 is attached to or removed from the thin plate material plating jig 10 will be described.
[0025]
As shown in FIGS. 1 and 3, the jig assisting device 30 includes a surface plate portion 32 on which the jig base 12 with the presser spring 14 attached is placed, and the surface plate portion 32. The presser release device 34 arranged in the same number as the presser spring 14 along both sides of the plate-like side 16 in the thin plate material plating jig 10 placed thereon, and the presser release device 34 are connected to the surface plate portion 32. Linear guides 36 that are supported at both sides in the width direction so as to be able to advance and retract in the width direction are provided. The same number of linear guides 36 as the presser release devices 34 are provided.
[0026]
The presser release device 34 is attached downward to the push-down lever 38 and the lift lever 40 pivotably supported in a vertical plane with a fulcrum shaft 37 as a common center, and to the tip of the push-down lever 38 downward in FIG. The outer region pressing tool 39, the lifting tool 41 attached upward to the tip of the lifting lever 40, and the pressing lever 38 and the lifting lever 40 are attached between the tip and the lifting lever 40. And an actuator 42 that swings about the fulcrum shaft 37 as a center.
[0027]
The actuator 42 causes the operating rod 42B of the air cylinder 42A attached to the upper side of the push-down lever 38 to protrude downward through the push-down lever 38, and swings on the lifting lever 40 side member via the pin 42C. It is configured to be freely connected.
[0028]
The fulcrum shaft 37 is horizontally supported by a base 44, and the base 44 is supported by the linear guide 36 so as to be movable forward and backward.
[0029]
The outer region pressing tool 39 enters the pair of screwing tool through holes 14E of the long side portion 14B downward so that the screw 24 can be pressed from above in FIGS.
[0030]
Further, the lifting tool 41 enters the tool through hole 14F upward from below the plate-like side 16, and the long side portion 14B can be lifted by the protruding tip.
[0031]
Further, the positions of the outer region pressing tool 39 and the lifting tool 41 in the left and right and the thickness direction in FIG. 3 and the distances between the tips of the outer region pressing tool 39 and the lifting tool 41 are as follows. The lifting tool 41 lifts the long side portion 14B, and the tip 15 is set to be separated from the surface of the inner region 18 by a certain distance or more.
[0032]
The surface plate portion 32 includes a downwardly convex concave arc surface 32A having a central axis parallel to the pair of plate-like sides 16 when the jig base 12 is placed. When the base 12 is pressed from above or pulled from below, it can be elastically deformed into a circular arc shape along the concave arc surface 32A.
[0033]
Next, a process of attaching and detaching the thin plate material 22 using the jig assisting device 30 to the thin plate material plating jig 10 according to the example of this embodiment will be described.
[0034]
First, the actuator 42 drives the push-down lever 38 and the lifting lever 40 so that the gap between the two is greatly opened, and the jig base 12 is placed on the concave arc surface 32 </ b> A of the surface plate portion 32.
[0035]
At this time, the rod side 17 connecting the pair of plate-like sides 16 and 16 in the jig base 12 is pushed down or pulled downward to elastically deform the jig base 12 along the concave arc surface 32A. .
[0036]
Next, as shown in FIG. 4, the push-down lever 38 and the lifting lever 40 are pulled by the actuator 42 so that the outer region presser tool 39 at the tip of the push-down lever 38 protrudes downward from the screwing tool through hole 14 </ b> E. At the same time, the lifting tool 41 at the tip of the lifting lever 40 protrudes upward from the tool through hole 14F to lift the long side portion 14B (see FIG. 5).
[0037]
As a result, the tip 15 of the presser spring 14 is separated from the surface of the inner region 18. In this state, the thin plate material 22 to be plated is placed on the jig base 12. At this time, both edge portions 22 </ b> A in the width direction of the thin plate material 22 cover the inner region 18.
[0038]
When the actuator 42 drives the push-down lever 38 and the lifting lever 40 in the closing direction, the outer region pressing tool 39 is separated from the screw 24 and the lifting tool 41 is also moved downward from the long side portion 14B of the pressing spring 14. The tip 15 of the presser spring 14 returns toward the inner region 18 by the spring force. At this time, the distal end 15 sandwiches the thin plate material 22 between the inner region 18 so as to push the width direction both end edges 22A of the thin plate material 22 into the linear groove 25.
[0039]
Next, when the external force pressing or pulling the jig base 12 against the concave arc surface 32A of the surface plate portion 32 is released, the jig base 12 returns to a flat plate shape.
[0040]
At this time, as schematically shown in FIG. 6, when the jig base 12 is assumed to be a bow, the thin plate member 22 has a bow string structure. Since both edge portions 22A in the width direction of the plate material 22 are pressed by the presser spring 14 and receive a tensile force in the direction of the central portion, they are pulled between a pair of plate-like sides 16 facing each other. Even if this occurs, it will be stretched.
[0041]
As a result, the thin plate material 22 is supported by being pulled in the shape of a straight plane without any wrinkles between the tips 15 of the presser springs 14.
[0042]
At this time, since both end edges 22A in the width direction of the thin plate material 22 are pressed into the linear grooves 25 formed in the inner region 18 by the tip 15 of the presser spring 14, a tensile force is applied to the thin plate material 22. Even if it is applied, the edge portions 22 </ b> A in the width direction will not come out of the tip 15 of the presser spring 14.
[0043]
In this way, the thin plate material 22 is strongly pulled in a flat plate shape between the pair of plate-like sides 16 and 16 facing each other, that is, the thin plate material 22 is fixed on the square frame-shaped jig base 12 in a straight plane state. It will be.
[0044]
Therefore, even if the thin plate material plating jig 10 with the thin plate material 22 attached is immersed in a plating tank (not shown) and the plating solution is stirred, the thin plate material 22 may be waved or deformed. Absent.
[0045]
After the completion of plating, the thin plate material plating jig 10 with the plated thin plate material 22 attached is placed on the surface plate portion 32 of the jig assisting device 30, and the presser release device 34 presses the presser spring. 14 is opened, the thin plate material 22 on which plating is completed is removed from the thin plate material plating jig 10, and the whole process is completed.
[0046]
In the example of the above-described embodiment, the presser release device that presses or releases the presser spring 14 includes the push-down lever 38, the lift lever 40, and the actuator 42 that drives them. The mechanism is not limited to the above, and other mechanisms or actuators may be used as long as the presser spring 14 can be released electrically or hydraulically.
[0047]
Furthermore, in the example of the above embodiment, the presser release device 34 and the linear guide 36 are provided for each plate-like side 16, but the present invention is not limited to this and is plated. The presser release device may be appropriately increased or decreased according to the size of the thin plate material, and the presser release device may press or release a plurality of presser springs simultaneously.
[0048]
Further, the outer region pressing tool 39 may be any tool that can form the reaction force of the lifting tool 41 by pressing the short side 14A or the outer region 20 without pressing the screw 24.
[0049]
