The invention discloses a shearing device for electromagnetic wires, relates to the technical field of assembly of electric reactors, and is designed to solve problems that shearing of the electromagnetic wires is time-consuming, labor-consuming and low in working efficiency. The shearing device for the electromagnetic wires comprises an upper base and a lower base, wherein both the upper base and the lower base adopt U-shaped frame structures; an upper blade is arranged between two side walls of the upper base, and the side edge, opposite to the cutting edge, of the upper blade is connected with an upper driving device for driving the upper blade to move up and down; a lower blade is arranged between two side walls of the lower base, and the side edge, opposite to the cutting edge, of the lower blade is connected with a lower driving device for driving the lower blade to move up and down; the upper blade and the lower blade move towards each other and can be engaged with each other. According to the shearing device, the upper driving device and the lower driving device drives the upper blade and the lower blade to move up and down respectively, so that the electromagnetic wires are sheared automatically, time and labor are saved, and the working efficiency is improved.
