External embedded coil winder

Abstract

The invention discloses an external embedded coil winder, includes a winding die disk having an outer diameter smaller than an inner diameter of a core slot, A meter-shaped win die support is coaxially arranged on that inner wall of the winding die disk, and a rectangular hole connected with a winding rotating device through a rectangular drive rod is arrange at the center of the meter-shaped winding die support for passing through the winding rotating device connected with the rectangular drive rod; Between that wire win die disk and the iron core slot, an adjustable limiting mechanism is arrange for limiting the conductor in the wire winding process. The invention has simple structure, and is mainly applied to the winding operation of the embedded coil outside the iron core of the electric power equipment. The coil can be directly wound in the iron core outer slot, the wire slot need not be divided and assembled, the manual wire arrangement is not required, the winded coil wire has tension, the coil is compact and is not easy to loosen. On the premise of ensuring the level of winding coil, the working efficiency is greatly improved, and it is convenient to use rotating equipmentto assist winding and reduce the labor intensity of operators.

Description

technical field [0001] The invention relates to the technical field of metal wire processing, in particular to a winding device for metal wires applied to embedded coils outside electrical equipment. Background technique [0002] Coils are contained in electrical equipment, such as transformers, reactors, inductors, solenoid valves, etc. The coils in these electrical equipment are mostly in the form of round, square or oval, and the coil winding is generally pre-wound on the winding die. The metal wire is obtained, and then directly inserted into the device (usually the iron core, hereinafter referred to as the core), but when the coil needs to be embedded in the device, the above method cannot be used to pre-wind the coil. Embedded coils are divided into two types: inner embedded and outer embedded; for inner embedded coils, the open coils at the outer ends of the wire slots on the core can be wound directly in the wire slots; for outer embedded coils, the coils on the core...

AI Technical Summary

Problems solved by technology

When this kind of embedded coil is built-in, the pre-wound coil needs to be put into the slot; when the outer diameter of the pre-wound coil will be larger than the protrusion, it cannot be directly placed in the winding slot; if To wind the coil directly in the inner cavity of the iron core, you can only arrange the wires one by one manually, and the wound wire is easy to loose because there is no fixture and tension, so the above-mentioned inner slot winding method is not suitable for external embedded Coil Winding
