摘要： Provided are a working method and an apparatus for bending a metallic mat erial three-dimensionally. A bending method for bending a metallic material supported by support means, downstream of the support means, while feeding t he same from the upstream to the downstream is used to manufacture a bent pr oduct having a three-dimensionally bent portion and a hardened portion inter mittently. The metallic material is partially heated downstream of the suppo rt means by metallic material heating means, and the position of a movable r oller die having a plurality of rolls arranged downstream of the heating mea ns for feeding the metallic material heated by the heating means in the axia l direction is three-dimensionally changed to bend that portion of the metal lic material, which is heated by the heating means, by applying a bending mo ment to that portion. The portion heated by the heating means is hardened by blowing a cooling medium by cooling means arranged between the heating mean s and the movable roller die. The metallic material is supported at its port ion having left the movable roller die, thereby to suppress the error of the bent product.

摘要： A method and apparatus for three-dimensionally bending a metal material are provided. A product intermittently having a bent portion which curves three-dimensionally and a quenched portion is manufactured by a bending method which performs bending downstream of a support means while feeding a metal material which is supported by the support means from an upstream side towards a downstream side. A portion of the metal material is heated by a heating means for the metal material downstream of the support means, a bending moment is imparted to the portion of the metal material which was heated by the heating means to carry out bending by three-dimensionally changing the position of a movable roller die which is disposed downstream of the heating means and has a plurality of rolls which feed the metal material which was heated by the heating means in the axial direction, and the metal material is quenched by spraying a cooling medium at the portion of the metal material which was heated by the heating means by a cooling means disposed between the heating means and the movable roller die. Errors in a product due to bending are suppressed by supporting a portion of the metal material which has exited from the movable roller die.

摘要： A metal tube for reinforcing car body, and a car body reinforcement according to the invention have a curved portion extending over the entire longitudinal length or a local longitudinal length, wherein, when the reinforcement is assembled such that the outer periphery of the curved portion is aligned substantially in the direction of impact applied to the car body, the load ramp gradient, the maximum load and the absorbed energy are all enhanced in case of a car body collision. Particularly, an increase in the load ramp gradient as for the load property at the start of deformation provides an excellent crash capacity in reinforcing the car body. Moreover, the metal tube and the reinforcement according to the invention are capable of satisfying the current requirements for much more crash capacity of the car body, along with both a weight reduction of the car body and a reduced manufacturing cost, and therefore they are applicable in a wide field for protecting occupants in an automobile.

摘要： A member for reinforcing a vehicle body capable of absorbing more energy than conventional reinforcement members using straight tubes and 'overall length R-bent tubes' at the time of collision of the vehicle body by applying either of a 'partially R-bent tube', a 'multi-portion R-bent tube' and a 'partially recessed and protruded bent tube' specified in this invention to the member for reinforcing the vehicle body so as to develop excellent impact resistance for reinforcing the vehicle body. The dimensions (outer diameter, wall thickness) of a metal tube used as the member for reinforcing the vehicle body are reduced while maintaining the impact resistance and the shape thereof is reviewed to reduce the weight and cost of the vehicle body. Also, since the member can cope with a requested level for a more and more increasing impact resistance of the vehicle body, it can be widely used as an occupant protective technology.
