The invention discloses a high-voltage lightning arrester lead wire making device, comprising a working plate, a rotary table hole is arranged on the working plate, a working table is rotatably arranged in the rotary table hole, a speed reduction motor which is relatively fixed with the working plate is arranged directly below the rotary table hole, and the main shaft of the speed reduction motoris vertically upward and fixedly connected with the working table; a lead grip block is fixedly arranged on the top surface of the working plate and on the outside of the rotary table hole. The side of the lead grip block facing the hole of the turntable is a concave structure in which both ends protrude and a semicircular concave surface is arranged inside. A lead grip block movable relative to the protruding end is arranged on the work plate and directly opposite to one of the protruding ends. A plurality of lead grip bending wheels movable in the semicircular concave surface with the rotation of the work plate are arranged on the work plate. The invention can complete the manufacturing work of the lead wire bending of the high-voltage lightning arrester on the work table, not only meeting the quality and process requirements during installation, but also has high manufacturing efficiency, ensures the consistency of the radians, and improves the safety coefficient of the site and theoverall aesthetics of the project.
