ランジ部を加工する方法の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing a flange portion of an automobile body, and more particularly to an improvement in a method for processing a flange portion by simultaneously bending each side edge of intersecting wall portions inward.

When processing a side edge of an automobile body member (work W) with a flange, as shown in FIG.
By lowering the workpiece W, the workpiece W is pressed and held by the planosaur 4' suspended from the punch bed 2' via a spring 3', and the workpiece W is held by the punch 5' fixed to the punch bed 2'. Each intersecting wall portion a of W.

、その結果コストアップを招くという問題があった。However, in the conventional processing method described above, the intersecting wall portions a,
Since each flange part c and +1 of b are bent at the same time, both flange parts c and d do not fold over each other at the change-over part e between both flange parts c and 4, and the corner part of the vehicle body after flange processing is folded. The part adjacent to f is shrunk and 7 lunge formed. As a result, combined with the fact that the flange width of the fork θ has been trimmed to improve workability, the bending radius of the vehicle body corner f becomes uneven after processing.
As shown in Fig. 6, it is formed in a protrusion shape, impairing the appearance quality of car body parts (work W) such as corner panels, and if the protrusion is still significant, extra work is required to repair it. This resulted in a problem of increased costs.

ものである。The present invention has been made in view of this point, and in a pre-process of processing the flange portion of the vehicle body member as described above, the bending radius of the portion corresponding to the vehicle body corner portion is stepped until the end of the radius. By preforming by processing, the purpose is to prevent the corner portions of the vehicle body from being formed into protrusions, thereby improving the appearance quality of the vehicle body member and reducing costs.

起が発生しないようにしたものである。'In order to achieve this object, the processing method of the present invention is a method of processing a flange portion by bending inward the side edge of an automobile body member having a wall portion where one side intersects with the other. First, a step process is performed to form a part of the flange portion of the vehicle body corner by recessing the part of the vehicle body member that is adjacent to the vehicle body corner after flange processing, and then the side edges of the vehicle body member are recessed. The flange part is processed by bending the part inward, and by stepping the bending R of the part corresponding to the corner of the vehicle body until the end of the R, the subsequent processing of the flange part is shortened and the flange ratio is reduced. This can be done so that the excess thickness of the flange portion does not affect the bending R of the corner portion of the vehicle body, thereby preventing the generation of protrusions on the corner portion of the vehicle body.

る。As shown in Fig. 2, a workpiece is formed into a shape in which the first wall part a intersects with the second wall part a, as shown by solid lines and dotted lines in Fig. 2, by the drawing process of squeezing the flat plate material. First, the W is trimmed into the shape shown by the dashed-dotted line in FIG. 2 by trimming to correct the irregular outline that has flowed during the drawing process. Note that g and h are notches that are trimmed at the same time in the trimming process described above in order to improve workability in the flange fabrication process that will be described later.

するものである。In the above trimming step, step processing, which is a feature of the processing method of the present invention, is simultaneously performed. As shown in Fig. 2, this step machining is performed by forming a stepped part i by recessing the part of the work W at the different fork part e and adjacent to the car body corner f after flange machining. It forms part of the flange portion of section f.

ことができる。That is, FIG. 3 shows the above-mentioned trimming process, in which the workpiece W formed in the first step is set on the die 1 having the cutting edge 1a on the upper side edge, and then the punch bed 2 is lowered to remove the punch. A punch 5 fixed to the punch bed 2 presses and holds the workpiece W with a plenosaur 4 suspended from the bed 2 via a spring 3.
The scrap j is removed by the cutting action of the cutting blade 5a provided on the lower side edge and the cutting blade 1a. At that time, the above die 1
A concave portion 1b and a convex portion 4a for stepped machining are respectively formed in portions of the planosaur 4 corresponding to the stepped portion i, and the stepped portion l is processed at the same time as the trimming described above. By this step processing, it is possible to preform the bending R of the vehicle body corner f up to the end of the radius in the pre-step of the seven-lunging process, and the shape of the vehicle body corner f can be determined in advance.

3, the side edges of the first and second wall portions a, b are simultaneously bent inward to form the first and second flange portions c, d, respectively (the state shown in FIG. 5).

。In this flange processing process, part of the flange part c, which should be formed at the same time as the flange part e, has already been formed as the stepped part i, so the flange part of the remaining part cannot be processed. This can be done by shrinking the flange ratio and reducing the flange ratio, and the excess thickness of the flange parts c and d can be done without affecting the bending R of the car body corner part f. The vehicle body corner f is not formed into a protrusion while maintaining its original shape.

果を奏し得るものである。As explained above, according to the processing method of the present invention, it is possible to dent the part of the car body member which has a wall part where one side intersects with the other and which is adjacent to the corner part of the car body after flange processing. bend a part of the flange part of the corner of the car body
The step process is performed by preforming to the end, and then the flange part is processed by reducing the shrinkage flange ratio and bending the side line part of the car body member inward, so the car body corner part is formed into a protruding shape. This has excellent practical effects in that it is possible to improve the appearance quality and reduce costs by preventing the occurrence of damage.
