Abstract

<P>PROBLEM TO BE SOLVED: To easily and simply join both first and second hollow panels from one side of the hollow panels. <P>SOLUTION: The lower board (the second board) of the first and the second panel projects longer to the opposite panel side than the upper board (the first board) respectively. Initially, the abutted part between the second boards is joined by welding or friction stir welding. Welding implements or the rotary tool 50 for the friction stir welding is inserted from a gap between the boards on the upper side. Then, a connecting material 30 is overlapped on the second board and welded or friction stir welded. The connecting material 30 is wound on a reel 300 and delivered while being rotated. As the joining material 30 is joined to the first and the second panel, it is unwound from the reel 300 concurrently. Thus, both sides of the hollow panels can be joined from the one upper side. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  According to the present invention, a hollow panel (for example, a hollow member, a member in which a hollow member is formed of a plurality of members (for example, a stainless steel double skin panel)) and a hollow panel are combined into two surfaces from one side. It is related with the method of joining.

  The hollow panel has two surfaces, an upper surface and a lower surface. For this reason, when connecting these hollow panels, it is necessary to connect two upper and lower surfaces.

  For this reason, the panel on the hollow is installed on the pedestal, the lower surface is joined from above, the joined panel is turned upside down, the plate material that was the upper surface is made the lower surface, and the plate material that was the lower surface is made the upper surface.

  Next, the plate material on the upper surface is joined from above.

  As described above, the upside down operation is necessary, and the double-sided joining of the hollow panels cannot be performed easily and easily.

  In order to solve this, Patent Document 1, Patent Document 2, and Patent Document 3 are presented.

  Patent document 1 is a panel of the shape material which carried out the extrusion molding as a hollow panel. Hereinafter, it is called an extruded profile.

  The end in the width direction of the first plate on the lower surface side of the extruded shape member protrudes from the second plate on the upper surface side. This hollow shape is abutted. The first plates on the lower surface side are butted against each other, but a gap is generated between the second plates on the upper surface side.

  For this reason, the first plates can be welded to each other from the gap, that is, from above.

  Next, a connecting material is disposed between the second plates on the upper surface side, and the plate and the second plate are welded from above.

  In Patent Document 2, instead of welding, joining is performed by friction stir welding.

  Patent document 3 uses spot welding as welding.

  In addition, a stainless steel plate is used as the material, and an overlapping portion is provided for joining the lower surface, and this is spot-welded.

  In these, the connecting material for connecting the hollow panels is a thin plate like the upper and lower plates of the hollow panel, the connecting material is easily bent to the plate thickness side, and considering the conveyance of the connecting material, the connecting material cannot be long. . When a hollow panel is used for a railway vehicle, its length is about 20 m, and it is practical that the length of the connecting material is about 1 m.

  An object of the present invention is to easily join both sides of a hollow panel from one side.

The above purpose is
In the method of joining the first panel and the second panel via a connecting material,
The first panel connects a first plate, a second plate substantially parallel to the first plate, a widthwise end of the first plate, and the second plate. And a third plate that
The second panel includes a first plate, a second plate substantially parallel to the first plate, and a third plate connecting the first plate and the second plate. Consists of
Joining the end in the width direction of the first plate of the first panel and the end in the width direction of the first plate of the second panel from the second plate side;
Next, the connecting member is disposed at an end portion in the width direction of the second plate of the first panel and an end portion in the width direction of the second plate of the second panel,
The connecting material is wound in a reel shape,
While extending from the reel, the connecting member is disposed at the widthwise end of the second panel of the first panel and the widthwise end of the second plate of the second panel. ,
Next, the arranged connecting material, the widthwise end of the second plate of the first panel, and the widthwise end of the second plate of the second panel are the first The panel, joining from the outside of the second panel;
Can be achieved.

  An embodiment of the present invention will be described below with reference to FIG.

  The panels 10 and 20 of FIG. 1 are made of an extruded aluminum material.

  The panel 10 includes a first plate 11, a second plate 13 that is substantially parallel to the first plate 11, and a third plate 15 that connects the end of the first plate 11 in the width direction and the second plate 13. And consist of The third plate 15 is substantially perpendicular to the first plate 11 and the second plate 13. Reference numeral 17 denotes a fourth plate that connects the first plate 11 and the second plate 13. The fourth plate 17 is arranged in a truss shape.

  The panel 20 includes a first plate 21, a second plate 23 that is substantially parallel to the first plate 21, and a third plate 25 that connects the end of the first plate 21 in the width direction and the second plate 22. And a fourth plate 27 that connects the first plate 21 and the second plate in a truss shape. That is, the second panel is substantially the same as the first panel.

  In order to join the panels 10 and 20, first, the first plates 11 and 21 are abutted, and the abutting portions are welded or friction stir joined from above. Since there is no first plate 11 or 21 above the butted portion, it can be joined from above. A welding tool and a stir welding rotary tool can be inserted from the gap between the first plates 11 and 21.

  Next, the connecting member 30 is disposed above the butted portion. The connecting member 30 is placed on the projecting pieces 19 and 29 at the ends of the first plates 11 and 21. By placing, the end of the connection member 30 is abutted against the second plates 11 and 21.

  This butted portion is welded or friction stir welded from above.

  The downward arrow in FIG.

  As described above, the connecting member 30 is thin, difficult to convey, and cannot be long, so that connection is difficult.

  Therefore, the connecting material 30 is wound in a reel shape. A reel 300 is called a reel 300.

The reel 300 is installed on a member 500 on which a welding tool or a friction stir welding rotary tool 50 is installed.

  From the reel 300, the connecting material 30 is fed out and placed on the projecting pieces 19 and 29, and welding or friction stir welding is performed.

  The welding instrument and the friction stir welding tool 50 move with respect to the panels 10 and 20 at a joining speed. Welding or friction stir welding is collectively referred to as joining.

  Between the reel 300 and the joint, there is a cylinder device 310 that presses the drawn connection material 30 downward with a predetermined pressure. A roller 320 is provided at the tip of the cylinder device 310 (the contact surface with the connecting member 30). The cylinder device 310 releases it when a reaction force higher than a predetermined air pressure is applied from the connecting material 30 side.

  The cylinder device 310 is installed on the member 500. The member 500 includes a reel 300, a cylinder device 310, and a friction stir welding tool 50. The member 500 travels to the right if the first panel 10 and the second panel do not move.

  The reel 300 has no power device to be rotated. Since the connecting member 30 is pulled by being connected to the hollow panel, the reel 300 rotates and the connecting member 30 is fed out.

  Since the friction stir welding tool 50 side is heavier, a rail 610 provided horizontally above the member is sandwiched between rollers 620 and 630 to prevent the member 500 from overturning. A post 640 supports the rollers 620 and 630.

  In FIG. 1, the third plates 15, 25 are orthogonal to the first plates 11, 21 and the second plates 13, 23 to support the bonding load when the connecting material 30 is friction stir welded. Because. The abutting portion between the connecting member 30 and the first plates 11 and 21 is in the range of the third plate thicknesses 15 and 25.

  In the above embodiment, the panels 10 and 20 are extruded shapes, but are not limited to extruded shapes, and may be stainless steel hollow materials as in Patent Document 3. In addition to the joining of the butted portions, lap joining may be used.

Further, the side to be joined to the butted portion of the second plates 13 and 23, that is, the first plate 11,
There may be a convex portion protruding to the 21 side. Similarly, there may be a protruding portion that protrudes upward in the abutting portion between the connecting member 30 and the first plates 11 and 21.

  When joining stainless steel, spot welding is preferable.

  After joining the connection material 30, the connection material 30 wound around the reel 300 is cut.
