摘要： A structure and method is realized for stably and at low cost carrying out an operation for forming a through hole 5c at one portion of a side wall 14 of an expanded portion 7a made by plastically deforming one part of a metal tube 3 radially outward, in a portion where the plate thickness gradually changes.
A slide tool 13b is withdrawn from inside a punch hole 12 while applying hydraulic pressure to the inside of the side wall 14. Regarding a tip end face 20a of the slide tool 13b, a portion facing the portion of the side wall 14 where the plate thickness is relatively thick is recessed. Due to this construction, at the instant of commencing withdrawal of the slide tool 13b, the degree of progress in the shearing for the portions of the side wall 14 matching with the two side edges of the punch hole 12a is made different. Then the timing for moving from shearing to rupture is made to coincide, so that of the side wall 14, the portions matching with the punch hole 12a, are made reliably into a blank 10c, and are extracted from the side wall 14.

摘要： A reducing mill according to the invention includes a plurality of stands disposed along a rolling direction line, in which a tube is rolled through the plurality of stands along the rolling direction line. The stands each include n rolls (n≥3) disposed around the rolling direction line, and the n rolls are disposed shifted by 180°/n around the rolling direction line from n rolls included in a preceding stand. The n rolls included in each of the plurality of stands excluding the last stand each have a groove having an arch shape in cross section. The bottom of the groove has a circular arc shape around the rolling direction line having a first radius in cross section, and the distance between the surface of a roll flange portion positioned between the bottom and the edge of the groove and the rolling direction line is longer than the first radius, and the distance between the edge of the groove and the rolling direction line is longer than the first radius in the groove of a roll included in the preceding stand. Therefore, the reducing mill according to the invention allows both polygon formation and roll edge marks to be suppressed.

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.
