Description

A Synchronous Die Loading Mechanism for a Coil Winding Machine

technical field

The present invention relates to a synchronous mold loading mechanism, in particular to a synchronous mold loading mechanism of a winding machine.

Background technique

The armature winding process is a crucial process link in the motor manufacturing process. There are two current motor rotor winding processes. One is the direct winding method, which uses some kind of machinery to directly wind the single-strand enameled wire in the slot of the rotor. Typical winding equipment is such as a flying fork winding machine; the other is the indirect winding method. The machine winds the enameled wire into a coil with the required number of turns, and then uses the wire embedding machine to embed the winding into the wire slot.

These two processes have been widely used in production practice, but the requirements are met at the same time: single-strand enameled wire windings, large slots, such as electric bicycle motors, each magnetic shoe of this motor is wound with a coil, and each turn of the coil It is also wound by multi-strand enameled wire, and the notch size is very small, only about 2mm. Due to the large space occupied by multi-strand wires and the problem of "twisted twist" during winding, the direct winding method cannot be used. The coil is tightly wound on the magnetic shoe, and the wire cannot be embedded, so the indirect winding method cannot be used. Since there is no mechanized equipment that can satisfy the assembly of this type of motor windings, at present, only manual winding is available, which not only has high production costs and low efficiency, but also has high labor intensity, which can easily cause workers’ knuckle joints to wear out and affect their health and well-being. quality of work.
