Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of forming a pillar flange that holds the peripheral edge of an automobile window glass.

[Prior Art] As shown in FIG. 4, a side edge of a front windshield 1 of an automobile is held by a front pillar 2. As shown in FIG.

By the way, as shown in FIG. 5, in the above-described front pillar 2, the inner panel 3 and the outer panel 4 are joined together with the outer panel 4 positioned with the bed 10 of the jig.
This is done by joining two pairs of joining flanges 5, 6 and 7, 8 provided at opposite ends of the outer panel 4, respectively. However, bed 1
Although it is possible to relatively accurately position the pair of joining flanges 5 and 6 on the 0 side, it is currently difficult to make the positioning accuracy of the pair of joining flanges 7 and 8 sufficiently high. For this reason, for example, if the joining flange 7 moves outward from the vehicle body, the trim 11 will no longer be stably supported by the inner panel 3, which will cause abnormal noise to occur between the trim 11 and the joining flange 8 on the outer panel 4 side during driving. If the fasteners (not shown) that fix the trim 11 to the inner panel 3 come off, problems such as irritation may occur.Conversely, if the joining flange 7 moves inward to the inside of the vehicle, the trim 11 may interfere with the front windshield 1. The problem arises that it becomes difficult to assemble the front window glass 1. Furthermore, if the joining flanges 7 and 8 are not accurately positioned, various problems other than those described above may occur, such as deformation of the trim 11 and poor alignment of the seaming welt 12.

As a countermeasure against this, although the cross-sectional shape is different from that of the front pillar 2, as shown in FIG. 6, the inner panel 13 is provided with a bent part 14 for positioning, and as shown in FIG. A separate positioning plate 16 may be disposed between them, or a bent part 17 for positioning may be formed at one end of the outer panel 15 and the end of the inner panel 13 may be brought into contact with the bent part 17, as shown in FIG. A positioning structure has been proposed (Utility Model Application No. 58-134182
(see publication).

However, in the structure shown in FIG. 6, the rigidity of the inner panel 13 decreases at the bent portion 14, and
In the structure shown in the figure, the number of parts increases due to the provision of the positioning plate 16, and the positioning accuracy of the positioning plate 16 with respect to the inner and outer panels 13, 15 is required, which makes it difficult to provide a fundamental solution. be. Furthermore, the eighth
In the structure shown in the figure, there is a problem in that the inner panel 13 curves toward the front of the vehicle body along the bent portion 17, as shown by the imaginary line in the enlarged partial view, and sufficient positioning accuracy cannot be obtained.

[Object of the Invention] The present invention has been made to solve the above-mentioned problems, and is capable of joining a joining flange while accurately positioning an inner panel and an outer panel, and in addition, a positioning structure is formed. It is an object of the present invention to provide a method for forming an automobile window glass peripheral pillar that does not remain on the pillar that has been formed.

[Structure of the Invention] Therefore, the present invention provides a method for forming a pillar at the periphery of an automobile windshield by joining both joining flanges of an inner panel and an outer panel so that the flange portion that holds the windshield holds the windshield. The joint flange of one panel is provided with at least two extension flanges exposed outwardly from the joint flange of the other panel, and each of the extension flanges is pre-drilled with a reference pin insertion hole. On the other hand, a concave portion recessed inward from the flange reference line of the end surface of the joint flange of the other panel is formed in advance at a portion of the joint flange of the other panel that faces the extension flange;
After positioning the other panel on the bed of the jig, overlap the one panel on the other panel, and use the reference pin inserted into the reference pin insertion hole of the one panel to insert the other panel. After joining the joint flanges of both panels with one panel positioned and both panels positioned, cut each of the above extension flanges at a position approximately flush with the flange reference line or inward from it. The present invention provides a method for forming pillars at the periphery of an automobile window glass, which is characterized by the following.

[Effects of the Invention] According to the present invention, one panel is positioned by the reference pin while the other panel is positioned by the bed of the jig.
It is possible to improve the positioning accuracy of the joining flange portions of both panels, thereby improving the alignment between the pillar and the window glass, trim, etc.

Furthermore, since it is only necessary to simultaneously form an extended flange for positioning when press-molding one of the panels, the number of parts for positioning the inner panel and the outer panel does not increase, and the rigidity of the pillar does not decrease.

Furthermore, after the two panels are joined, the extension flange is cut approximately flush with the flange reference line of the other panel, or at a position inside of it, so that after assembling the window glass to the pillar,
The base of the extension flange is not exposed on the window glass, so providing the extension flange for positioning does not impair the appearance.

[Example] Hereinafter, an example will be described with reference to FIGS. 1 to 3.

FIG. 1 shows a front pillar having substantially the same cross-sectional shape as the conventional example shown in FIG.
Joint flange 22 on the front windshield side of
As shown in FIG. In addition, each extension flange 25 has a reference pin 26 of the jig.
Elongated holes 27 into which are inserted are formed respectively. or,
At a portion of the joint flange 24 on the outer panel 23 side facing the extension flanges 25, 25, there is a concave portion 28 which has a slightly larger vertical width than the extension flange 25 and is recessed inward from the flange reference line 32 on the end surface of the joint flange 24. It is formed.

When joining both panels 21 and 23, as shown in FIG.
The reference pin 2 is inserted into the elongated hole 27 of each extension flange 25 of 1.
6 to position the inner panel 21 with respect to the outer panel 23. The reference pin 26 is moved in and out by a cylinder or the like (not shown), and its position is set in advance with respect to the bed 10 so that both joining flanges 22 and 24 are accurately positioned when inserted into the elongated hole 27. .

In this state, the inner panel 21 and outer panel 2
After joining the joint flanges 22, 24 and 30, 31 of No. 3 by spot welding or the like, the extension flanges 2
5 and 25 are joint flanges 2 on the outer panel 23 side
The extension flanges 25, 25 are removed by cutting along the cutting line A--A, which is substantially flush with the flange reference line 32 or located inward from the flange reference line 32 on the end face of the flange 4. Therefore, the problem of the extension flanges 25, 25 being exposed on the front windshield after the front windshield is assembled to the front pillar 20 can be prevented, and the appearance will not be impaired.

In the above embodiment, the extension flange 25 through which the reference pin 26 is inserted is provided in the joint flange 22 on the inner panel 21 side.
An extension flange 25 may be provided on the side joining flange 24, and the inner panel 21 may be supported by the bed during joining. Also, extension flange 2
By providing three or more joint flanges 5, it is possible to further improve the positioning accuracy of both joining flanges 22, 24. Furthermore, it goes without saying that the present invention can be applied not only to front pillars but also to rear pillars.
