摘要： A press-working apparatus capable of forming a clear character line. The press-working apparatus forms a product having a character line. The press-working apparatus comprises an upper die and a lower die arranged across a steel sheet, an upper die mechanism for moving the upper die toward and away from the lower die, a first holder and a second holder for clamping the steel sheet and applying an unwrinkling force to the same, and a control unit for controlling the upper die mechanism and the first holder. The upper die is divided on the character line of the product into a first upper die and a second upper die. The control unit makes the unwrinkling force by the first holder stronger than that by the second holder, so that the steel sheet is press-worked by the second upper die and then by the first upper die.

摘要： A forming speed determination method for determining a forming speed of a press-processing device with a plurality of measurement points on a sheet material to conduct press-forming of the sheet material with a press-processing device at a predetermined forming speed. Strain states at respective points on the press-formed sheet material are plotted on a forming limit diagram including the forming limit curve of a sheet material to produce a strain distribution chart. Subsequently, the closest point to the forming limit curve among the points is defined as a specific measurement point. When this specific measurement point is located in the bulge region, the forming speed of a press-processing device is decreased to be slower than the above-mentioned predetermined forming speed. Meanwhile, when this specific measurement point is located in the draw region, the forming speed of a press-processing device is increased to be faster than the above-mentioned predetermined forming speed.

摘要： In a 3-dimensional animation generating apparatus which uses a computer, the user generates a number of static images having parent-child relationships and which serve as key frames in the sequence from the start to the end of the animation, a number of animation frames specified by the user being automatically inserted between the key frames by means of interpolation. In this 3-dimensional animation generating apparatus, the times of each of the key frames as specified by the user are stored, the parent object coordinates and child object coordinates generated by the user are stored in a world coordinate system, along with parent-child relationship in each of the key frames. When the 3-dimensional animation generating apparatus generates interpolated frames, the parent-child relationship in neighboring key frames in the time sequence is interpolated to first generate the parent-child relationship existing in the interpolated frame, after which the parent object coordinates in the interpolated frame are calculated in the world coordinate system by interpolating the parent object coordinates in each of the neighboring key frames. The coordinates of a child object in an interpolated frame are determined from the parent-child relationship within the interpolated frame and the parent object coordinates in the interpolated frame. The animation is thus generated from the interpolated frame parent object coordinates, the interpolated frame child object coordinates, and the parent-child relationship.

摘要： A bulging apparatus has a heating station, a tube expanding station, a preforming station, and a main forming station. A straight tube as a workpiece is gripped by first holding mechanisms or second holding mechanisms, and delivered between the stations as the first holding mechanisms or second holding mechanisms are displaced. During a preforming process and a main holding process, both the first holding mechanisms and second holding mechanisms can be lifted and lowered vertically and can be moved horizontally.
