초록

A method of manufacturing an elliptic deep-drawn product including a first step of providing an intermediate product and a second step of providing an end product. In the first step, a rotary forming die is used to form in a blank a substantially round formed portion of a U-shaped cross-section. In the second step, the formed portion is deformed at its semicircular portion by press working to form an elliptic portion, being formed into a final shape.

What is claimed is: 1. A method of manufacturing an elliptic deep-drawn product, comprising: a first series of steps of providing an intermediate product, the steps including placing a blank on a spinning forming die, pressing the blank onto the forming die with a spinning bar, and forming a substantially round formed portion of a U-shaped cross-section; and a second series of steps of providing an end product, the steps including placing the intermediate product in a press working die, and causing deformation with the press working die in a semicircle...
