摘要： PROBLEM TO BE SOLVED: To provide a cylindrical impact energy absorbing member having annular reinforcing parts and annular non-reinforcing parts alternately and capable of consistently obtaining the excellent impact energy absorbing performance and finely adjusting the absorption characteristic of the impact energy. SOLUTION: A body part (an impact energy absorbing member) 20 is constituted by using square pipes 30, and annular reinforcing parts 26 are provided on the square pipes 30 by executing the quenching at the predetermined interval. Thus, sufficient strength difference can be given between the annular reinforcing parts 26 and annular non-reinforcing parts 28, and the high impact energy absorbing performance can be obtained, and the annular non-reinforcing parts 28 are preferentially deformed to realize consistent behavior during the buckling in the bellows shape. The annular reinforcing parts 26 can be provided with the high positional accuracy. Thus, the impact energy absorbing performance is further consistent, and the degree of versatility for setting the forming pattern or the like of the annular reinforcing parts 26 becomes high, and the absorption characteristic of the impact energy can be finely adjusted.

摘要： PROBLEM TO BE SOLVED: To eliminate the requirement for a positioning pin to protrude/retract, to inexpensively construct a forming device in a simple manner, and to restrict any positional deviation of the plate-shaped workpiece for achieving the high forming accuracy.
SOLUTION: A plate-shaped workpiece 16 is highly accurately positioned by a pilot opening 20b formed in a center part in the longitudinal direction, and since the hot pressing is performed while pilot openings 20a-20c including the pilot opening 20b are engaged with positioning pins 22a-22c, the forming accuracy is enhanced. Since the hot pressing is performed while pilot openings 20a-20c are engaged with positioning pins 22a-22c, the cycle time is shortened and forming efficiency is improved, and the maintenance burden is reduced according to the reduction of the number of movable parts, and the forming cost is also reduced. Meanwhile, since the positioning pins 22a-22c can be integrally fixed to a lower press die 12, the forming device can be inexpensively constructed in a simple manner.

摘要： PROBLEM TO BE SOLVED: To provide a heat treatment method of a plated steel sheet for hot pressing, a method in which a hot-press formed article having sufficient coating adhesion and corrosion resistance can be stably obtained. SOLUTION: According to this heat treatment method of a plated steel sheet for hot pressing, the plated steel sheet is heat treated before hot pressing in which rapid cooling for quenching is performed in a press mold. For this purpose, a slab specimen 10 is heated in the atmosphere in which oxygen concentration is >0 volume % or in which oxygen concentration is ≥0 volume % with dew point ≥0°C. Accordingly, on the surface of the slab specimen 10, there is formed a metallic oxide layer of the plating material, namely, a barrier layer such as zinc oxide or zinc hydroxide, for example. Thus, rapid oxidation is suitably suppressed when the article is taken out from a heating furnace, enabling the hot-pressed article to be stably obtained that has sufficient coating adhesion and corrosion resistance.
