摘要： PROBLEM TO BE SOLVED: To provide an Al-Mg-Si type aluminum alloy extruded material to which a prescribed proof stress value is given by aging treatment by regulating the plastic strain of an extruded material to a predetermined value. SOLUTION: An Al-Mg-Si type aluminum alloy is extruded. Then, >=0.2% plastic strain is applied to the resultant extruded material by plastic deformation such as straightening, followed by aging treatment. As the Al-Mg-Si type aluminum alloy, an aluminum alloy containing 0.25-0.9% Si, 0.4-1.2% Mg, 0.1-0.3% Fe, 0.005-0.2% Ti and 0.001-0.01% B and further containing, if necessary, one or more kinds among 0.01-0.4% Cu, 0.05-0.2% Cr, 0.05-0.2% Zr and 0.05-0.3% Mn is used.

摘要： PROBLEM TO BE SOLVED: To efficiently improve bending accuracy by specifying a measurable factor with little dispersion, controlling a spring back quantity, and adjusting a bending moment according to a measured value, in the bend-working of an extruded shape using a movable bending die whose bending radius or bending angle can be adjusted according to a moving amount. SOLUTION: A working condition compensating a spring back quantity is determined by measuring the hardness of an object to be worked at the time of bend-working and converting obtained hardness into a yield strength value. For instance, the ratio of the theoretical moving amount and the actual moving amount of a movable bending die is set to a correction factor. This correction factor is expressed by the functional formula of the Young's modulus, the section modulus, the yield strength value and the bending radius of the object to be worked. A constant in the functional formula is previously determined by an experiment, etc. At the time of bend-working, the hardness of the object to be worked is measured, and obtained hardness is converted into the yield strength value. A correction factor is found by substituting the yield strength value for the functional formula with a necessary bending radius. Bend- working is performed by determining the actual moving amount of the movable bending die. This method is suitably applied to an A6063 material as well.

摘要： PURPOSE: To provide an integrated hollow product of high strength at a low cost by forming a recessed part or a deformed part in an extruded Al alloy hollow stock to make the preliminary shape close to the designed one, and realizing the designed shape by bulging the preliminarily shaped member. CONSTITUTION: An Aluminum alloy hollow product 1 is provided with a flange 10 on the side along the longitudinal direction, and recessed parts 11, 12 and a flat part 13 are locally formed on the corner of the upper part. The prescribed parts of a hollow stock corresponding to the recessed parts 11, 12 and the flat part 13 of the hollow product 1 are pressed by a press jig to be worked as a preliminary shape close to the designed shape of the hollow product 1. Then the hollow stock is placed in a bulging die consisting of an upper die and a lower die, both ends of the hollow stock are covered by a piston rod, the liquid is fed from a high pressure liquid feeding passage, and the liquid is pressurized to manufacture the hollow product 1 of the designed shape. Because the product is of integrated shape, and free from any joined parts, the strength is high, and the joining process is dispensed with, and the hollow product 1 can be manufactured at a low cost.

摘要： PURPOSE:To enable the cryogenic press forming of an aluminum sheet by press forming aluminum or aluminum alloy sheet at =50wt.% natural fats and oils or natural fat and oil polymers is applied on the surfaces of the aluminum sheet 11. This aluminum sheet 11 is immersed into liquid nitrogen kept at -196 deg.C, by which the aluminum sheet and the lubricating oil are sufficiently cooled. The aluminum sheet is then pulled up and is set to a punch 3 of a press device 1. A die 5 is, thereupon, lowered to press form the aluminum sheet when the aluminum sheet, etc., cool down to the prescribed temp. below -50 deg.C. The natural fat and oil polymers are formed by blowing oxygen to the natural fats and oils or triglyceride while applying heat thereto to cause an intramolecular polymn. and have high flexibility at
