摘要： The invention provides: a method for bending a workpiece in which, in a bending process, while successively or continuously feeding the workpiece held by a supporting unit from an upstream side of the supporting unit, bending is performed at a downstream side of the supporting unit; a bending machine; and a bending-equipment line. The bending method includes: supporting the metal material with a movable roller die; controlling the position of the movable roller die and/or the moving speed of the metal material; heating the metal material in a temperature range in which the heated portion can be plastically deformed and in a temperature range in which quenching can be performed, by using a heating unit that is provided around the outer circumference of the metal material, to apply a bending moment to the heated portion; and rapidly cooling the heated portion, by using a cooling unit that is provided around the outer circumference of the metal material. According to the present invention, even in a two-dimensional or three-dimensional continuous bending operation in which the metal material is two-dimensionally or three-dimensionally bent in different directions, and even when a high-strength metal material is bent, it is possible to effectively obtain a metal material having excellent shape fixability and uniform hardness distribution at low costs. Therefore, the bending method of the invention can be widely applied as an art for bending sophisticated automobile parts.

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.

摘要： An impact absorption member for a vehicle, in which both ends in the axial direction of a tubular body section (52) are constructed from thick plates (62, 64) having a thickness of 1.4 mm or greater, and this enables the body section (52) to be excellently welded and secured in a butted state to installation plates (54, 56) by arc welding. By this construction, a lightweight and inexpensive crush box (50) exhibiting predetermined impact energy absorbing performance is constructed without using a bracket etc. Further, an intermediate section of the body section (52) is constructed from a thin plate (60) having a thickness less than 1.4 mm, so that the weight of the impact absorption member is reduced with predetermined impact energy absorbing performance maintained. In addition, because the plate is thinned, the impact absorption member collapses at a lower load to provide an impact energy absorption effect.

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.
