PURPOSE:To accurately shape a flatwise coil in an isosceles trapezoidal shape by sequentially automatically operating functions of end clamping the coil, clamping the linear portion, turning, open shaping, shaping the end and correcting, by preparatory planning directly from a coil shaping drawing. CONSTITUTION:A frame 18 is secured onto a trestle 17, and various shaping mechanisms are placed. First, the linear portions a-b, c-d of a coil 1 before shaping are respectively clamped to clamping mechanisms C1, C2, and end portions (l), (f) are clamped by a clamp 27. Then, the linear portion a-b is raised by a cylinder 44b in a direction of an arrow Alla, and the linear portion c-d is lowered in a direction of an arrow A11b by a cylinder 44a, opened and shaped. Subsequently, the linear portions a-b and c-d are turned in directions of arrows A14a, 14b by cylinders 34a, 34b at the fulcra O, P as centers. Thereafter, it is corrected in a direction of an arrow A12 by a cylinder 50, the end portions (l), (f) are then shaped by a heading machine in a direction of arrow A13 by a cylinder 25, thereby completing the shaping. |
