関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is suitable for automobile parts and building parts such as frames and bumpers which require bending.
The present invention relates to an aluminum or aluminum alloy extruded material for bending.

いる。2. Description of the Related Art Aluminum or aluminum alloys are:
It has the advantages of being lighter than iron and less likely to rust. Further, the extruded material has an advantage that it can be extruded in an arbitrary cross-sectional shape, and thus has been widely used for housing sashes and automobile parts. Among the automobile parts, for example, the frame material needs to be bent into a desired shape from an aluminum or aluminum alloy extruded material,
In particular, it is important to improve the appearance quality such as wrinkles and deformation and to improve the minimum bending radius (improve the bending limit). In addition, further weight reduction is required in the future to improve fuel efficiency, and extruded materials are becoming thinner and more difficult to bend.

下するなどの欠点があった。As a method of suppressing wrinkles at the time of bending, use of rosary cores and fillings is known. However, a rosary core as disclosed in JP-A-6-174449 has a complicated structure, and requires a core that matches the cross-sectional shape of the extruded material. In addition, a low melting point metal or ice is used instead of the core. When processing by packing (for example,
No. 943) takes a long time to insert and elute, resulting in poor productivity and increased cost. Alternatively, the extruded material may be formed into a cross-sectional shape having a middle rib. However, this has a disadvantage that the weight of the extruded material is increased by the middle rib and the extrusion speed is reduced.

In Japanese Patent Application Laid-Open No. 4-55022), the minimum bending radius is also determined by the buckling of the extruded end surface on the side where the extruded material is sent from the fixed jig to the movable jig side during the bending process. There was a limit to thinning.

わたり貼り付けられていることが望ましい。The aluminum or aluminum alloy extruded material for bending according to the present invention has a resin reinforcing material attached to at least one surface constituting a cross section of the extruded material along a longitudinal direction. It is characterized by being.
Preferred resin reinforcing materials include thermosetting resin reinforcing materials. This resin reinforcing material, when affixed to a bent portion, has an effect of restraining deformation occurring at the time of bending, and reducing deformation such as wrinkles and warpage caused by bending. Further, the wrinkles and warpage are reduced, so that the minimum bending radius (bending processing limit) is improved. In this sense, it is desirable that the adhesive be applied over the entire length of the bent portion (from the start position to the end position of the bending process).

You can also. In this case, the side where the resin reinforcing material is attached is the side where the extruded material is sent out from the fixed jig to the movable jig side.
This has the effect of increasing the rigidity of the end of the extruded material, preventing buckling of the extruded end face, and improving the minimum bending radius (bending limit) of the extruded material.

半径が向上するからである。The bent member obtained by bending the extruded material according to the present invention is most suitable for a frame material of an automobile. In other words, an automobile frame is required to have a cross section with less deformation (wrinkles and warpages) in terms of body rigidity, parts attachment and appearance, and a structural member that requires a small bending radius as designed. By using the applied extruded material, deformation such as wrinkles and warpage is reduced, and the minimum bending radius is improved.
