Abstract

PURPOSE:To decrease the man-hour, to improve the yield and to manufacture the aluminum strength member by cutting an aluminum extrusion shape while extruding from an extruding machine and working the above with warm pressing, etc. CONSTITUTION:An aluminum extruded member 11 while extruding from the extruding machine 10 is cut by the prescribed length with a flying shear 12. This cut piece 11A is transferred to the direction orthogonally to the extruding direction, heated to the prescribed temperature with an in-line heater 13, worked with warm pressing or hot pressing with a pressing machine 13 and made to the semi-products. Therefore, the material yield is improved, the man-hour is decreased and the aluminum strength member of complex shape can be manufactured.

The aluminum extruded shape being extruded from the extruder is cut into a predetermined length by a flying shear and then pressed, so that scrap is prevented from occurring and the material yield is improved. In addition, since the press working is performed warm or hot, the number of steps is reduced, and a product having a complicated shape can be easily manufactured. Moreover, since the cut pieces are obtained by cutting the aluminum extruded shape being extruded from the extruder, the temperature thereof is high, and heating to the press working temperature is easy or unnecessary. Furthermore, since the aluminum extruded shape member is used, the reinforcing material can be integrally formed.
