押出材製の部品及びその製法

Parts made by extruded material and its manufacturing method for this material

Abstract

【課題】中空部を有する閉断面を、中空部が延びる方向において所望の形状に簡単に構成できる押出材製部品及びその製法を提供する。 【解決手段】ブレイス10は、第1の工程として、中空部22を有する断面が押出方向に一定形状で連続する押出材21を、断面を保って分割することにより基本材15を形成し、第2の工程として、押出材21と同一材を、断面が押出方向で異形になるように中空部22で分割することにより、その分割によって形成される面25が基本材15の右壁26に閉断面になるように固定される副材20を形成し、第3の工程として、副材20の面25を、基本材15の右壁26に接合することによって構成される構造とした。これにより、複数種類の押出材を必要とせず、副材20の形状を調節することにより、ブレイス10の中空部22を有する断面の形状が調節される。 【選択図】 図2
PROBLEM TO BE SOLVED: To provide parts made by extruded material and its manufacturing method capable of easily constituting a closed cross section surface having a hollow portion in a desired shape in a direction in which the hollow portion extends. SOLUTION: A brace 10 is constituted by three processes: in a first process, the extruded material 21 of which the cross section surface having the hollow portion 22 continues in the extruded direction in a constant form is divided with the cross section surface kept to form basic material 15, in the second process, the identical material with the extruded material 21 is divided at the hollow portion 22 so that the cross section surface may become different form in the extruded direction, and auxiliary material 20 fixed so that a surface 25 formed by this division may become a closed cross section surface to a right wall 26 of the basic material 15 is formed, and in the third process, the surface 25 of the auxiliary material 20 is jointed with the right wall 26 of the basic material 15. Therefore, the plural kinds of extruded material are not necessary, and the form of the cross section surface having the hollow portion 22 of the brace 10 can be adjusted by adjusting the form of the auxiliary material 20.
