Automatic winding device for reactor coil

Abstract

The invention discloses an automatic winding device of a reactor coil, which comprises a pay-off mechanism and a winding mechanism, wherein the pay-off mechanism comprises a pay-off rack and a wire coil, the wire coil is arranged on the pay-off rack, the winding mechanism comprises a winding machine and a winding tool, and the winding tool is arranged between two tips of the winding machine; a guide rail is arranged on the ground at the bottom of the pay-off rack and is parallel to the axis of the tip; the winding tool comprises an elastic die, an inner supporting plate and a cross, the elastic die is cylindrical, and an adjusting seam is axially formed on the elastic die; the two inner supporting plates are respectively arranged at two ends of the elastic die and are clamped on the innersurface of the elastic die; the number of the cross is two, and the elastic die is clamped between the two crosses. The wire coil can translate in the direction parallel to the axial direction of thecoil along with the winding of the wire during paying off, so that the wire pressing is effectively prevented; and after the coil is wound and shaped, the wire coil can be quickly demolded, so that the production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of reactor production, in particular to an automatic winding device for reactor coils. Background technique [0002] Reactors are mainly used in power systems to limit short-circuit current, reactive power compensation and phase shifting, and are inductive high-voltage electrical appliances. The reactor is generally in the form of a wire wound into a solenoid, which is called an air-core reactor. Sometimes in order to make the solenoid have greater inductance, an iron core is inserted into the solenoid, which is called an iron core reactor. With the acceleration of my country's power grid construction, the expansion of scale, and the increasing load of electricity, the role of reactors in the power system is becoming more and more important, and the demand is also increasing. It is imperative to improve the production efficiency of reactors. [0003] Reactor production includes processes such as winding, so...

Problems solved by technology

[0004] The coil molds used in traditional coil winding are generally made of wood and hard aluminum to form the required size and shape, such as a cylindrical or square cylindrical structure with a fixed shape. Because of its fixed shape and the wires are close to the coil mold Winding, it is very inconvenient to demould after the coil winding is completed; in addition, in the prior art, the wire reel is generally placed on a pay-off rack at a fixed position to pay off the wire. When winding, if the pay-off rack is fixed at a position Moving or moving in any direction at will will easily cause the wire to be pressed on the coil mold, which will affect the coil winding quality
