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 control data preparation method for a pressing through bending machine capable of realizing bending in conformance with design as much as possible in addition to conventional bending. SOLUTION: Respective local coordinate systems xy specified based on a fixed die of a pressing through bending machine are set in respective cross sections 65a-65g of a long size product 51. Based on adjoining local coordinate systems xy, a specific twisting angle around axis per unit feed quantity specified in the axial direction of the long size product 51 is calculated. Based on the calculated specific twisting angle around axis. The relative rotation angle around axis between a fixed die and a moving die of the pressing through bending machine relatively rotating around axis is calculated. Based on the relative rotation angle around axis derived in this way, the rotation of the fixed die and the moving die of the pressing through bending machine around axis is controlled, thus twisting deformation is applied to the long size stock in a relatively high precision.

摘要： PROBLEM TO BE SOLVED: To provide a control data preparation method for twisting which enables application of precise twisting to a long size stock in accordance with design by using a pair of dies rotating each other around the axis of the long size stock without depending on the perception and empiricism of a worker. SOLUTION: Based on a twisting angle Δθ around the axis of a long size product 51 specified with the shape data representing a shape of the long size product 51, the twisting moment applied to the long size stock is calculated. Based on the calculated twisting moment, an elasto-plastic twisting deformation quantity caused to the long size stock between a first die and a second die rotating each other around the axis is calculated. The elasto-plastic twisting deformation quantity calculated is added to a relative rotation angle around axis calculated based on the shape data. Thus, an actual rotation angle around axis is specified between the first die and the second die corresponding to the elasto-plastic twisting deformation quantity, the shape error of the long size product due to elastic restoring force, that is, spring back is sufficiently eliminated.
