Description: TECHNICAL FIELD The present invention relates to a molding method for forming a roof by mounting a reinforcement on a roof panel of a vehicle having a sunroof opening.

[Prior Art] This type of roof includes a roof panel 1 having a sunroof opening 1a and a frame-shaped reinforcement 2 as shown in Figs.

In this roof panel 1, a roof vertical flange portion 1b is formed over the entire circumference at the peripheral portion of the quadrangular sunroof opening 1a. On the other hand, the reinforcement 2 has a sunroof opening 1a.
It has a frame-like shape having a size corresponding to the peripheral edge portion, a reinforcement vertical flange portion 2a is formed on the inner peripheral edge portion, and a plurality of touch embossed portions 2b are formed at predetermined locations as shown in FIG. , Multiple stud bolts as shown in FIG.
2c is provided.

Next, the assembling of the roof panel 1 and the reinforcement 2 will be described. First, the press-molded roof panel 1 is placed on the camber receiver 3. In this state, as shown in FIG. 9, the roof panel 1 is
The roof panel 1 does not have a predetermined curved shape, and is in a state of floating with respect to the camber receiver 3.

Place the reinforcement 2 on the roof panel 1
As shown in FIG. 10, the reinforcement 2 is pressed downward by the clamp head 4 so that the touch embossed portions 2b projecting downward at a plurality of points of the reinforcement 2 are brought into contact with the roof panel 1. Then, the roof panel 1 is formed into a predetermined curved shape along the receiving surface 3a of the camber receiver 3.

Next, the vertical flange portions 1b and 2a are spot-welded with the back bar 5 applied to the vertical flanges 1b and 2a.

Then, as shown in Fig. 11, the roof vertical flange
A paint seal 6 is applied between the upper end of 1b and the reinforcement vertical flange 2a.

As a result, the roof having a predetermined curved surface shape is formed.

[Problems to be Solved by the Invention] However, in such a conventional one, since the roof panel 1 is pressed via the touch embossed portion 2b of the reinforcement 2, the touch embossed portion 2b is pressed. As a result, a protruding portion is generated on the roof panel 1. Further, the touch embossed portions 2b are provided at several places with intervals. In other words, since it is difficult to form the touch embossed portion 2b continuously in terms of manufacturing, the force that pushes the roof panel 1 is weak in the portion without the touch embossed portion 2b. There is a possibility that the receiving surface 3a cannot be reliably brought into contact with the receiving surface 3a.

[Means for Solving the Problem] The present invention has been made in view of the above-mentioned conventional problems, and a roof panel having a sunroof opening is mounted on a camber receiver, and a frame is provided around the sunroof opening on the roof panel. -Like reinforcement is placed and pressed from above to make the roof panel a predetermined curved shape along the receiving surface of the camber receiver, and then a roof vertical flange formed at the peripheral edge of the sunroof opening of the roof panel. Section and a reinforcement vertical flange portion formed on the inner peripheral edge portion of the reinforcement by surface contact with each other, in a roof molding method for an automobile, wherein the roof vertical flange is mounted with the reinforcement on the roof panel. Make sure that the height of the upper end of the section is equal to or higher than the height of the upper end of the reinforcement vertical flange of the above-mentioned reinforcement. Set to
A method for forming a roof for an automobile, comprising forming a predetermined curved shape along the receiving surface of the roof panel by bringing a clamp head into contact with an upper end of a roof vertical flange portion of the roof panel and pressing the clamp head downward. Is characterized by.

[Operation] According to such means, the upper end of the roof vertical flange portion is directly pressed by the clamp head to form the roof panel into a predetermined curved shape, so that the touch embossed portion presses the roof panel as in the conventional case. Therefore, the roof panel is not deformed by the touch embossed portion.

Further, the roof vertical flange portion can be formed continuously with the roof opening. In other words, unlike the touch embossed portion, the roof vertical flange portion can be formed over the entire circumference. By pressing the flange portion, the peripheral edge of the roof opening can be pressed uniformly over the entire circumference, and unlike the conventional case, the entire roof panel can be formed into a predetermined shape along the receiving surface of the camber receiver. .

[Examples] Hereinafter, the present invention will be described based on Examples.

1 and 2 are views showing an embodiment of the present invention.

In this automobile roof, a reinforcement 2 is joined to a roof panel 1 having a sunroof opening 1a, and the roof panel 1 is formed in a predetermined curved shape.

When the reinforcement 2 is mounted on the roof panel 1, the position of the upper end 1c of the roof vertical flange portion 1b and the position of the upper end 2d of the reinforcement vertical flange portion are substantially the same height. Other configurations of the roof panel 1 and the reinforcement 2 are the same as those of the conventional example.

Next, the assembling of the roof panel 1 and the reinforcement 2 will be described. First, the roof panel 1 in which the sunroof opening 1a, the roof vertical flange portion 1b, and the like are previously formed by pressing is set on the camber receiver 3. In this state, the roof panel 1 does not have a predetermined curved surface shape, and the roof panel 1 is in a state of floating with respect to the receiving surface 3a of the camber receiver 3.

Then, the reinforcement 2 is set on the roof panel 1. In this state, the roof panel 1 and the reinforcement 2 have both vertical flange portions 1a, 1b formed on the peripheral edge portions.
The heights of both upper ends 1c and 2d are substantially the same. Then, the clamp head 11 is brought into contact with the upper ends 1c, 2d of the vertical flange portions 1b, 2a and pressed downward to directly press the roof vertical flange portion 1b of the roof panel 1 to camber the roof panel 1. It is formed in a predetermined curved shape along the receiving surface 3a of the receiver 3. In this case, the touch embossed portion 2b formed on the reinforcement 2 comes into contact with the roof panel 1, but the touch embossed portion of the reinforcement 2 is different from the conventional one.
Since the roof panel 1 is not pressed to form a predetermined curved surface via 2b, the contact force is small, and the touch embossed portion 2b does not deform the roof panel 1. The touch embossed portion 2b has a function of positioning the reinforcement vertical flange portion 2a in the height direction with respect to the roof vertical flange portion 1b. If the roof panel 1 is fitted with the reinforcement 2 for positioning, the touch embossed portion 2b can be eliminated.

The movement of the clamp head 11 will now be described. When the cylinder rod 13 is lowered by the cylinder 12, for example, the L-shaped second link is passed through the first link 14.
15 rotates counterclockwise about the first shaft 16. Then, the extension portion 17a extending upward of the arm 17 is connected to the second link 15 by the second shaft 18, so that the arm 17 rotates upward about the third shaft 19. As a result, the clamp head 11 provided at the tip of the arm 17 moves upward and retracts from the flanges 1b and 2a.
When pressing the roof vertical flange portion 1b downward with the clamp head 11, the operation opposite to the above is performed.

After forming the roof panel 1 into a predetermined curved surface shape, the back bar 20 is spot-welded with the roof vertical flange portion 1b of the roof panel 1 and the reinforcement vertical flange portion 2a of the reinforcement 2 in contact with each other.

Then, as shown in FIG. 2, both vertical flange portions 1b, 2
A tape seal 21 is attached to both upper ends 1c and 2d of the same height of a to seal them.

As a result, a roof having a predetermined curved surface shape is formed.

Roof vertical flange 1b formed continuously in this way
Since the upper end 1c of the roof is directly pressed, the roof panel 1 is pressed over the whole unlike the conventional touch embossed parts 2b formed at a plurality of positions press the roof panel 1. Thus, it is formed into a predetermined curved shape.

Also, by making the heights of the upper ends 1c, 2d of both vertical flange portions 1b, 2a substantially the same as described above, the upper ends 1c, 2d of both vertical flange portions 1b, 2a are sealed with the tape seal 21. Therefore, unlike the conventional one in which the upper end 2d (end) of the reinforcement vertical flange 2a is exposed,
Rust prevention of both vertical flange portions 1b and 2a is ensured.

As in the above embodiment, the upper end 1c of both vertical flange portions 1b, 2a,
If the heights of 2d are set to be almost the same, it becomes easier to secure the sealing performance. However, the upper end of the vertical flange 1b of the roof panel 1 is the vertical flange portion of the reinforcement 2.
It may be formed higher than the upper end of 2a.

That is, according to the present invention, the upper end 1c of the vertical bulge portion 1b of the roof panel 1 is pressed by the clamp head 11 to make the roof panel 1 along the receiving surface 3a of the camber receiver 3 into a predetermined curved shape. In this state, the intended purpose is to form the roof panel 1 into a predetermined shape by spot welding both the roof vertical flange portion 1b of the roof panel 1 and the reinforcement vertical flange portion 2a of the reinforcement 2. Because it is something to achieve.

As long as the upper end 1c of the vertical flange portion 1b of the roof panel 1a is formed higher than the upper end of the reinforcement vertical flange portion 2a, at the initial stage of assembly, the upper end 2d of the reinforcement vertical flange portion 2a is the roof vertical flange portion. 1b
Even if the upper end 2d of the vertical flange 2a is projected by the pressing operation of the clamp head 11,
Is pressed to a height equal to or lower than the upper end 1c of the roof vertical flange portion 1b, and the upper end 1c of the roof vertical flange portion 1b is always pressed by the clamp head 11, so that the roof panel 1 is formed into a shape along the camber receiving surface 3a. Because it is formed.

[Effects of the Invention] As described above, according to the present invention, the height of the upper end of the roof vertical flange portion is the upper end of the reinforcement vertical flange portion of the above-mentioned reinforcement when the roof panel is provided with the reinforcement. By setting the height of the roof panel above the height of the roof panel and pressing the clamp by abutting the upper end of the roof vertical flange portion of the roof panel, the roof panel is formed into a predetermined curved surface shape along the receiving surface. , It is not necessary to press the roof panel through the touch embossed portion of the reinforcement unlike the conventional case, so that the deformation of the roof panel can be prevented and the roof vertical flange formed over the entire circumference of the roof opening. By directly pressing the part, the peripheral edge of the roof opening of the roof panel can be pressed over the entire surface, and the receiving surface of the camber receiver Can be formed into a predetermined shape along
It has a practically useful effect.
