Abstract

PURPOSE:To improve the shape of the product, at the time of bending at least at two parts or more, by bending the part with small bending angle first, then bending the part with larger bending angle. CONSTITUTION:The first bending is performed on the first bending part having a smaller bending degree of the pipe 1, inserting a core bar 8 by setting clamp dies 7a, 7b. Then, the bending part where a large bending degree larger than the first bending is required, is performed similarly. By this method, the external appearance and dimensional accuracy of the product is improved.
