Embodiment Construction

[0024] The invention discloses a winding die for making a forming winding with a large-gauge round copper wire. In addition to ensuring the cross-sectional size of the straight side of the coil, a specially designed layer-changing shaping groove at the end can greatly increase the shaping operation space and ensure the coil size.

[0025] For ease of understanding, the terms involved in this solution are explained as follows:

[0026] Formed hard winding: It needs to be solidified after winding, and the winding can only be embedded in the core slot after the shape is fixed;

[0027] Transposition: Multi-layer wire winding requires transition between different layers.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention....

Abstract

The invention discloses a winding mold for producing a formed winding by using large-wire-gauge circular copper wires. On the basis of ensuring the cross-sectional dimension of the linear side of a coil, and an end portion layer replacement shaping groove is specially designed on an original closed pressure plate so that a shaping tool (such as shaping bar) can pass through the end portion layer replacement shaping groove, thereby greatly increasing the shaping operation space of the end portion of the coil, reducing the operational difficulty at the coil winding layer replacement position, and ensuring a coil size.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a winding die for making a forming winding with a large-gauge round copper wire. Background technique [0002] When round wire is used for winding production, it is generally wound into a loose winding, which is a loose embedded winding. With the development of AC traction motor technology, due to the compact structure of the motor and the increasing power, higher requirements are placed on the motor slot full rate. Traction motor windings are often made of flat copper wires to form hard windings, and now they are gradually There are motors that need to be manufactured with round wires into formed hard windings. [0003] Due to the limitation of round wire manufacturing and winding manufacturing process, each motor core slot needs round wire to be wound into the required number of turns, there are more turns of round wire in the width and height of the slot, and the follow-up nee...
