METHOD FOR MANUFACTURING L-SHAPED PRODUCT

摘要

Disclosed is a method for manufacturing an L-shaped product (10), the L-shaped product (10) including an L-shaped flat upper wall (12), an inner sidewall (14) extended along and coupled to an inner edge portion (12c) of the upper wall, and an outer sidewall (16) extended along and coupled to an outer edge portion (12d) of the upper wall, wherein the inner sidewall and the outer sidewall are terminated at flange portions (18, 20), respectively, which are generally parallel to the upper wall. The method includes the steps of preparing a metal sheet material, preparing a drawing die assembly, and pressing the metal sheet material with the drawing die assembly in order to manufacture an intermediate product. The method further includes the steps of preparing a bending die assembly and further pressing the intermediate product with the bending die assembly, thereby providing a completed L-shaped product.
