Definitions
- the present invention relates to a hollow member. Specifically, the present invention relates to a lightweight hollow member having excellent rigidity and impact characteristics.
- Metal strength members, reinforcing members or structural members are used in automobiles and various machines. These members are required to have high strength, light weight, and small size. Conventionally, these members have been manufactured by a processing means such as welding of a pressed product, punching of a thick plate, or forging. However, it is extremely difficult to further reduce the weight or size of the members manufactured by these manufacturing methods. For example, when manufacturing a welded product by overlapping and welding two pressed panels, it is necessary to provide a surplus portion called a flange on the edge of the panel, so the weight of the welded product is It will inevitably increase by the amount that forms the surplus part.
- hydroform In a processing method called hydroform (see, for example, Non-Patent Document 1), the outer surface of the pipe is aligned with the inner surface of the mold by introducing a high-pressure working fluid into the pipe, which is a material arranged in the mold.
- the tube is formed into a complicated shape by inflating and deforming the tube. Complex shaped parts are integrally formed by hydroforming without the need to form a flange.
- hydroforms are actively applied to automobile parts because they can reduce the weight of automobile parts.
- Hydroform is a cold process. For this reason, for example, it is difficult to form a high-strength material such as 780 MPa or more into an automobile part having a complicated shape because the material has insufficient ductility.
- the manufacturing process of hydroform is relatively complicated because three processes of bending, preforming and hydroforming are generally required. Furthermore, hydroforming machines are large and relatively expensive.

- the hollow members 11 to 13 can be easily manufactured by using a machining apparatus obtained by modifying a part of the machining apparatus 0 shown in FIG. That is, the rolls constituting the support means 2 and the movable roller die 4 of the processing apparatus 0 are replaced with hole-type rolls that can support the outer surfaces of the hollow members 11 to 13, and the position of the movable roller die 4 is three-dimensionally changed.

- this processing apparatus 0 uses quenching for forming the twisted portion 17, the tensile strength of the twisted portion 17 can be easily increased to 780 MPa or more. Further, the twisted portion 17 has excellent fatigue characteristics. The reason for this will be explained.
- a hollow member having a high strength such as 780 MPa or 980 MPa can only be twisted into a product having a twisted portion with a very large bending radius because the material has poor ductility. Even if estimated to be low, a residual stress (tensile residual stress) of +200 MPa or more is likely to occur on the surface of this product. As is well known, when tensile residual stress is generated on the surface of a product, the fatigue characteristics when the product is repeatedly deformed are greatly reduced.
- the twisted portion 17 formed by the processing apparatus 0 is formed by hot twisting. A large tensile residual stress generated by cold twisting is not generated in the twisted portion 17.

- the result of having measured the residual stress (unit: MPa) of the surface in the axial direction of the product obtained by twisting with a twist angle of 0.2 ° / mm per unit by the X-ray stress measurement method is shown.
- Table 2 shows the measurement results of the residual stress on the circumferential surface of this product.
- the angles in Tables 1 and 2 are the positions in the circumferential direction, and are the measurement position angles when the angle of the upper surface center position in the lateral direction of 50 mm is 0 degree.
- the X-ray measuring instrument used for the measurement of the residual stress is MXP-3 manufactured by Mac Science Co., Ltd. (current name: Bruker AXS Co., Ltd.).
- At least the twisted portion 17 has a residual stress of +150 MPa or less, preferably a residual stress of +50 MPa or less. More preferably, at least almost all of the twisted portion 17 has residual compressive stress. For this reason, the fatigue characteristics of this product are extremely excellent.
- FIG. 6 is an explanatory view showing a hollow member 19 having a first twisted portion 17-1, a second twisted portion 17-2, and a bent portion 18.
- the first twisted portion 17-1 and the second twisted portion 17-2 are formed in the main body 20 of the hollow member 19.
- the bent portion 18 has a first portion 21 existing on one side in the longitudinal direction of the main body 20 with the first twisted portion 17-1 as a boundary, and a main body 20 with the second twisted portion 17-2 as a boundary. Between the first portion 22 and the first portion 22 on one side in the longitudinal direction.

In addition, it is possible to provide a lightweight hollow member having excellent collision characteristics.
