Description

Device and method for separating enameled wire and iron core of motor stator winding

technical field

The invention relates to a device and a separation method for separating enameled wires and iron cores of motor stator windings.

Background technique

Considering environmental protection and recycling of precious metals, it is very important to dismantle and recycle waste motors. However, there is still a lack of equipment for separating the enameled wire in the motor stator winding from the iron core. Most of them use manual separation, which is labor-intensive and inefficient, and the operator is prone to injury accidents. At present, the separation methods commonly used at home and abroad are mainly:

In countries such as Europe and the United States, the entire stator winding is cooled with liquid nitrogen first, and then crushed at low temperature. This method has high equipment costs, high energy consumption, high noise, and serious wear during the crushing process. The silicon steel sheets on the iron core cannot be reused after being crushed, and multi-stage separation is required when different metals are mixed together.

The commonly used method in China is to cut off the clusters of enameled wires with a chisel on the two end faces of the stator winding, or use scissors to cut off the clusters of enameled wires, and then heat the stator windings on the stove. , so that the plastic that wraps the enameled wire in the core slot softens, and then use pliers to pull out the clusters of enameled wires. This method is only suitable for individual maintenance or recycling. Although the equipment is simple, it is labor-intensive and low-efficiency, and is not suitable for mass production. Moreover, when the plastic is heated, it will produce toxic gas, which is harmful to health and is not conducive to environmental protection.

Chinese patent CN2610553Y discloses a device for separating the iron core of the motor winding from the enameled wire. The device has poor adaptability to stator windings of different shapes and sizes, and the operation is cumbersome and unsafe. It should be pointed out that: according to its public literature, for the use of this device, one end of the winding iron core needs to be cut off with a lathe first, but practice has proved that the fluffy enameled wire at one end of the winding iron core cannot be cut off with a lathe.

Chinese patent CN86206971U discloses a kind of dismantling device of electric motor winding, is to cut electric motor winding with rotary cutter earlier, then removes electric motor winding with automatic locking wire-drawing hook and automatic pressing wire-drawing clip. The disadvantages are: the motor winding is required to rotate 360° with the fixture during the cutting process, which increases the complexity of the mechanism; the winding iron core needs to be heated, which will generate toxic fumes; the enameled wire is pulled out by clusters, and the efficiency is low ; Cutting and wire drawing are not the same equipment, the whole device is huge and complicated, uses many motors, consumes a lot of energy, and is not easy to operate.
