押出材の成形用ダイスを要旨とする。Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a forming hole having a forming hole having a predetermined cross-sectional shape and a thin-walled portion forming hole adjacently connected to the hole. An extrusion die provided with the extrusion die, wherein the extrusion thickness in the thin-walled part forming hole is regulated to 1/2 or less of the extrusion thickness in the molding main body forming hole, and the extrusion thickness in the thin-walled part forming hole is The holes for forming the thin-walled part and the holes for forming the main body of the molded material are arranged such that the speed of the extruded material passing through the holes for forming the thin-walled part and the forming hole for the main body of the molded material is within a range of more than one time and less than twice the speed of the extruded material passing through the holes for forming the main body of the molded material. The gist of the present invention is a die for forming an extruded material having a wavy thin-walled part, characterized in that the relationship between the lengths of both bearings of the part is determined.

な波状薄肉部を形成するためであり、これが１倍以下で
あると押出材の薄肉部に波を生じず、また、２倍を超え
ると押出材に亀裂等の欠陥が生じ易くなる。The speed of the extruded material passing through the hole for forming the thin-walled part is within a range of more than one time and less than twice the speed of the extruded material passing through the hole for forming the main body of the molded material. This is to form an appropriate wavy thin part. If this is less than 1 time, no waves will be formed in the thin part of the extruded material, and if it is more than 2 times, defects such as cracks will easily occur in the extruded material.

可能性がある。Furthermore, the extrusion thickness in the thin-walled part forming hole is regulated to 1/2 or less of the extrusion thickness in the molding main body forming hole, so that the waveform is formed only in the thin-walled part of the extruded material. If this is larger than 1/2, there is a possibility that the wave formed in the thin part of the extruded material will affect the main body of the shape material.

出材が得られる。Function: In the extrusion die described above, the extruded material passing through the thin-walled part forming hole passes through the extruded material relatively faster than the extruded material passing through the mold body forming hole. The extruded material passing through both holes is extruded in a mutually connected state, and the above-mentioned difference in extruded thickness causes the thin part of the extruded material to become wavy. An extruded material with wavy thin-walled portions is obtained.

たような更に大きな差が与えられるのが一般的である。Generally, if the bearing lengths a and A of the image forming holes (5a) and (5b) are equal, the shape material body forming hole (5a)
The extruded material passing through is extruded faster than the extruded material passing through the thin-walled part forming hole (5b). In order to equalize the speed of the extruded material passing through each forming hole (5a) (5b), the bearing length a of the thin-walled part forming hole (5b) should be shortened, and the shape body forming hole should be shortened. It is necessary to make the bearing length A of the portion (5a) longer than that. Incidentally, in the confirmation experiment described later, in order to equalize the speed of the extruded material passing through each forming hole (5a) (5b), the bearing length a of the thin-walled part forming hole (5b) was set to 1.5. #, it was necessary to provide a considerable difference in the bearing length A of the shape body forming hole (5a) to 6.0tttut. Therefore, since the die (1) of the present invention forms the thin part of the extruded material in a wave shape, it is possible to create a larger difference between the bearing lengths a and A that could not have been predicted up to now. is common.

。Incidentally, extrusion was carried out by varying the ratio of the speed of the extruded material passing through the thin-walled part forming hole (5b) and the speed of the extruded material passing through the mold body forming hole (5a), and the extruded material was obtained. When the extruded materials were investigated, the results shown in Table 1 were obtained. In addition, the die (1) used had an extrusion thickness T of 3M,
The width B is set to 35#, the extrusion thickness t of the thin-walled part forming hole (5b) is set to 1 rin, the width is set to 10#+, and the billet is A6.
063 alloy was used. In addition, the speed ratio in the table is evaluated by dividing the length of the wave at the tip of the thin wall portion (7b) in the length range by the unit length of the main body portion (7a).

The relationship between them is such that the speed of the extruded material passing through the thin-walled part forming hole (5b) is more than one time and less than twice the speed of the extruded material passing through the mold body forming hole (5a). It was confirmed that by setting the speed to be the same, it was possible to obtain an extruded material (7) having an appropriate wavy thin wall portion (7b) without cracking.
