Abstract (en)
[origin: EP3000542A1] Provided is a bending press device and a steel pipe manufacturing device where an amount of seam gap of an open seam pipe can be appropriately controlled. In a bending press device provided with an open seam edge measurement device where a punch pressing-down amount is set after measuring an amount of seam gap of an open seam pipe, the open seam edge measurement device includes a light projector and a light receiver mounted on the punch, a detection circuit and a control part. The open seam edge measurement device measures an amount of gap between a punch support portion and an open seam edge of an open seam pipe which is a material to be formed, and the punch pressing-down amount is controlled based on the measured amount of gap.
