A device and method for manufacturing a shunt reactor core pull rod

Abstract

The present invention relates to a device and method for manufacturing a shunt reactor core tie rod, belonging to the technical field of power transformer processing. The technical solution is: an assembly tool (13) comprises a steel pipe (8), a lead screw (9), a tightening bolt (10), a torque wrench (11) and a sleeve (12); the number of the steel pipes (8) is two, the two steel pipes are sleeved on a small tie rod (1), a gap (15) is provided between the two steel pipes, and one end of the two steel pipes is connected by a lead screw, and the other end is respectively provided with a bolt hole, and the steel pipe and the small tie rod (1) are fixedly connected through the bolt hole and the tightening bolt (10); an observation hole (14) is provided on the steel pipe, through which the state of the small tie rod in the steel pipe can be observed; a torque wrench is provided at one end of the small tie rod, the torque wrench is connected to the sleeve, and the sleeve matches the recessed nut (3). The beneficial effects of the present invention are: the tie rod can be manufactured efficiently, the quality of the tie rod is guaranteed, the manufacturing cost is reduced, and the work efficiency is improved.
