Manufacturing method for spiral copper bend

The invention relates to the technical field of material machining and forming, in particular to a manufacturing method for a spiral copper bend. The manufacturing method includes the following steps that firstly, a long-bar-shaped copper material is straightened; secondly, the initial end of the long-bar-shaped copper material is fixed to the outer circumferential surface of one end of a cylindrical winding clamp, and the other end, opposite to the winding clamp, of the long-bar-shaped copper material is inclined; thirdly, the winding clamp is rotated around the axis so that the long-bar-shaped copper material is spirally wound on the clamp to form the spiral copper bend. According to the manufacturing method, the winding clamp rotates so that the spiral copper bend can be made, manufacturing is simple, convenient and flexible, spiral copper bends of various complex structures can be made, the clamp is simple in structure, the production cost is low, and the manufacturing method can be suitable for uninterrupted and small-batched product production.
