摘要： A forming simulation method of an elastic-plastic material, which includes: calculating an element equivalent nodal force vector from stress tensor using a finite element method for one or a plurality of finite elements of a target configuration of the elastic-plastic material; and calculating the total equivalent nodal force vector of areas by integrating the element equivalent nodal force vector for the calculated one or more finite elements over all the areas or specified areas of the elastic-plastic material.

摘要： A condition setting calculation device (104) compares an actual performance value of a material characteristic transmitted from a material characteristic data providing device (101) via a network (105) with a standard value, and corrects forming conditions such as a forming speed and a blank-holder pressure in accordance with the compared result. A control device (103) controls a press-forming device (102) to start a press-process of a material to be processed (300) with the corrected forming condition. Accordingly, it becomes possible to reduce occurrences of cracks and wrinkles as much as possible when the material to be processed (300) is press-processed, and to obtain good products of substantially identical shape.

摘要： A strip tip restriction apparatus capable of gripping the distal end of a strip and moving it at a high speed from the exit of a finish rolling mill to a down coiler while imparting a tension to the strip is disposed on a strip cooling line so disposed as to extend between the finish rolling mill and the down coiler of a hot strip rolling mill, and a pinch roll and a cooling water jet apparatus constituting the strip cooling line are allowed to move in a direction of the upper and lower surfaces of the strip in accordance with the movement of the strip tip restriction apparatus. Furthermore, an auxiliary driving apparatus for imparting initial acceleration to the strip tip restriction apparatus and/or a strip edge retaining apparatus for easily moving the distal end portion of the hot strip from the strip tip restriction apparatus to the down coiler are provided to the hot strip rolling mill.

摘要： A high-strength part that excels in hydrogen embrittlement resistance and strength after high-temperature forming; and a process for producing the same. The atmosphere in a heating furnace before forming is regulated to one of = 10% hydrogen volume fraction and = 30°C dew point. As a result, the amount of hydrogen penetrating in a steel sheet during heating is reduced. After forming, there are sequentially carried out quench hardening in die assembly and post-working. As the method of post-working, there can be mentioned shearing followed by re-shearing or compression forming of sheared edge portion; punching with a cutting blade having a gradient portion at which the width of blade base is continuously reduced; punching with a punching tool having a curved blade with a protrudent configuration at the tip of cutting blade part, the curved blade having a shoulder portion of given curvature radius and/or given angle; fusion cutting; etc. Consequently, the tensile residual stress after punching is reduced and the performance of hydrogen embrittlement resistance is improved.
