Uniform-pressure electromagnetic forming device, uniform-pressure coil and obtaining method thereof

The invention provides a uniform-pressure electromagnetic forming device, a uniform-pressure coil and an obtaining method thereof. The uniform-pressure electromagnetic forming device comprises a conductive channel, a coil and a workpiece. The U-shaped conductive channel is formed in an upper-portion surrounding coil of the coil, the workpiece is arranged below the coil, and the workpiece and the conductive channel form a current loop. The coil comprises a lead, an epoxy plate and a reinforcing material. A framework composed of the epoxy plate provides supporting for the lead. The reinforcing material is arranged on the outer side of the lead to serve as an outer reinforcing layer and used for providing enough strength. During work, eddy current is sensed in the workpiece and the conductive channel due to the influence of changing current in the coils, and the current loop is formed. Due to the fact the coil is formed by winding multiple layers and turns of thinner red copper leads, an electromagnetic force ex
