摘要： The present invention has its object to provide an efficient, general use shaping technique for forming high strength sheet metal into a three-dimensionally complicated shape. Further, the present invention provides a working apparatus for shaping sheet metal comprising a die (also called a “punch”) which has a shape suitable for a shape of shaped sheet metal, a plurality of rolls which grip sheet metal (H) with the die to shape the sheet metal, roll movement mechanisms which makes the rolls independently move in a horizontal direction and make them independently ascend or descend in a vertical direction, and a roll angle setting mechanism which can change an angle by which the rolls are pressed against the die.

摘要： An inner hole 31 to which a driving shaft 2 is inserted is formed in a campiece 3 of a camshaft 1, and a plurality of grooves 34 extending in the insertion direction of the driving shaft 2 are formed in the inner hole 31. The driving shaft 2 is inserted into the inner hole 31 with the cam piece 3 heated to expand the diameter of the inner hole 31. By reducing again the diameter of the inner hole 31 by cooling it in this state, an outer circumferential surface of the driving shaft 2 is pressed and raised by the inner hole 31 and enters the groove 34, by which the cam piece 3 is firmly fixed onto the driving shaft 2.

摘要： A computer performs press forming analysis based on a shape of a formed product or of a member, a blank holder force, a friction coefficient, a tensile strength of a material, a yield strength, a stress-strain relation, and a sheet thickness, as press forming conditions, to calculate sheet thickness distribution and post-formation strain distribution of the formed product. The computer also performs performance analysis based on the sheet thickness distribution, the post-formation strain distribution, and the shape of the formed product or of the member, as state amounts of the formed product. This calculate performance of the member. The computer repeats the calculations performed in the process from the first step through the second step a predetermined number of times, with at least one of the press forming conditions being changed, to output an optimum press forming condition that gives a maximum value or a target value of the performance
