[0002] Industrial coils are generally wound using a winding machine and a winding die. First, the coil inner die is put on the winding die, and then the winding die is fixed on the winding machine. The winding machine drives the coil inner die to rotate, so that the coil is wound on the inner die, thereby realizing the winding of the coil.

[0003] When winding the coil, the current adjustable wire winding mold needs to be covered with a cardboard tube and held tightly by the winding mold. Then the support bar is glued to the cardboard tube and the coil is wound. Before winding, a process paper tube must be placed to complete the winding of the coil. When winding the high-voltage coil, since there are corner rings at both ends of the coil, pressure must be applied to both ends of the coil so that the coil can meet the requirements. The coil is easily damaged when turning over, which is troublesome to operate. In addition, the demand for process equipment is large and the production efficiency is low. The use of cardboard tubes not only increases costs, but also prolongs the production cycle.

[0004] Based on this, an adjustable winding die is now provided to eliminate the drawbacks of the existing device. Utility Model Content
