Description

Belt drive double set roller enamelled flat wire conductor forming device

technical field

The invention relates to a conductor forming device, in particular to a conductor forming device for enamelled flat wire with double sets of rollers driven by a belt.

Background technique

Motors account for a large proportion of energy consumption. Most high-power motor coils use enamelled flat wires. In order to improve the efficiency of motors, the rounded corners of enameled flat wire conductors are required to be minimized. At present, the forming of enamelled flat wire conductors is realized by cold drawing process. The existing problems are that the deformation of the small rounded corners of the conductors is uneven, the rounded corners are not completely formed, and the surface roughness is large, which leads to the reduction of the mechanical properties of the conductors, and at the same time causes There are a series of quality problems in the subsequent process of paint film coating, paint film forming, and paint layer performance, such as uneven thickness of paint film, poor insulation performance of rounded corners, and paint film is prone to peeling and cracking when bending. The invention aims at forming enamelled flat wire conductors, and solves the problem of forming small round corners of enamelled flat wire conductors.
