Winding device and method of window type irregular saddle-shaped coil

The invention relates to the technical field of manufacturing processes of window type irregular saddle-shaped coils for compound function electromagnets, in particular to a winding device and method of a window type irregular saddle-shaped coil. The window type irregular saddle-shaped coil comprises step components which are unfolded with two 90-degree flanges on two edges and used for controlling gaps among copper wires of each layer at the 90-degree flanges, the upper edges of wire cakes on each layer are guaranteed to be flush on the same plane after flanging, the step component at one end is horizontally divided into three parts, and gaps are reserved in the middles and used for accommodating copper wire heads, the three parts are fixed on a base plate through locating pins and bolts respectively. A 90-degree back plate is located above the step component with coils unfolded at two ends and used for unfolding two ends of each wire cake to vertical positions layer by layer through a special tool after lay
