摘要： PROBLEM TO BE SOLVED: To provide an extruded aluminum material excellent in precise bending workability, and having uniform proof stress values where buckling is not oc curred even in extrusion bending, and to provide its production method. SOLUTION: In the method for producing an aluminum extruded shape material produced by subjecting an aluminum alloy billet to homogenizing treatment, subjecting the same to extrusion and cooling and thereafter performing aging treatment, at the time of the above aging treatment, at least one or more samples are taken from the cooled extruded materials, this sample is subjected to preceding aging treatment, simultaneously, its mechanical properties are evaluated, and based on the same, aging treatment conditions are set in such a manner that 0.2% proof stress is controlled to 120 to 140 MPa, and elongation is controlled to >=12%. By this method, an aluminum extruded shape material having 0.2% proof stress optimum for bending, small in the variations of bending precision and proof stress value and free from the generation of buckling even in extrusion bending can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a forming technique, in which the generation of chips and a burr is suppressed in a cutting process and a forming cost is wholly reduced.
SOLUTION: In a press-forming method, grooves 28 having a U-shape cross section are formed in flange parts 27. The product 26 for draw-forming is placed on a base 31 of a bend-forming machine 30. Blade receiving parts 32 are disposed around the base 31, and the flange parts 27 are received by the blade receiving parts 32. By lowering punches 33 in a way that the punches 33 are passed between the base 31 and the blade receiving parts 32, separating scrap parts 34 from the flange parts 27 and bending the flange parts 27 downward are carried out at the same time. Cutting is easily and surely conducted by the presence of the grooves, and completed without generating the burr due to no use of a cutting blade.

摘要： PROBLEM TO BE SOLVED: To reduce the forming hours with lower internal pressure, and lessen the decrease in plate thickness upon forming a metallic hollow member by hot bulging. SOLUTION: Clamping an upper mold 3 and a lower mold 4 of a mold 2 provides a first forming cavity 8 and a second forming cavity 9. A round pipe stock P0 is set in the first forming cavity 8, subsequently openings at both ends are sealed with a sealing member 16 of a shaft pushing cylinder unit 14, simultaneously being heated by passing current via an electrode 11 while being pushed axially. A compressed air is applied inside the pipe to form an intermediate pipe product P1. Simultaneously, the previously formed P1 is set in the second forming cavity 9, subsequently openings at both ends are sealed with a sealing member 17, while being heated by passing a current via an electrode 12 to produce a final pipe product P2 with air pressure applied inside the pipe.

摘要： PROBLEM TO BE SOLVED: To provide a control data preparation method for twisting while enables application of twisting to a long size stock in a twisting angle differing along the axis by using a pair of dies rotating relatively each other around the axis of a long size stock. SOLUTION: A twisting angle ψ around the axis per unit length specified in the axial direction, that is, in the direction of a line of centroid, that is, a specific twisting angle around the axis in the direction of a line of centriod is calculated based on shape data. A distribution curve 71 showing the variation in the specific twisting angle ψ around the axis is depicted in the direction of a line of centriod. In the distribution curve 71 before the maximum value, an approach distance L measured between a pair of dies is multiplied by the specific twisting angle ψ, a relative rotation angle C required between a pair of dies is derived. In the distribution curve 71 after the maximum value, the relative rotation angle C is specified by the integral value of the specific twisting angles ψ around the axis calculated over the approach distance L.

The tube is cut to a prescribed length. The tube is bent with a tube bender to form a shape close to a product shape. The tube is made to a forming material 45 by connecting end parts. The forming material 45 is charged into a blowing forming die 10, which has a cavity regulating an external peripheral face of a product. The forming material 45 is heated to the softening point or higher through under the melting point. A high pressure fluid is blown into the forming material 45 to be subjected to blow forming.
