A 2D forming tooling and forming process for copper wire of a card-sending motor

Abstract

The invention relates to a copper wire 2D forming tool for a card generator, which includes a chassis, a number of positioning holes arranged on the chassis, an angle positioning member arranged on the chassis through the positioning holes and whose position can be adjusted, a central column on the chassis fixedly arranged, Rotate the turntable connected to the center column, the handle connected to the outer surface of the turntable, the wire groove fixedly arranged above the chassis, the adjustment block slidably connected to the wire groove and the stop post detachably connected to the turntable, the Both the retaining column and the wire groove are arranged radially along the center column, and the inner and outer walls of the retaining column are close to the inner end of the channel, the top of the angle positioning member is higher than the bottom end of the handle, and the handle and the inner end of the channel are close together. The contact surface of the angle positioning part is an inclined plane; the 2D forming tooling for the copper wire of the hairpin motor of the present invention can realize the flexible processing of the copper wire and meet the processing requirements of the shapes of the copper wires of each layer; Easy to operate.

Description

technical field [0001] The invention belongs to the technical field of bending flat-wire motor stator copper wires, and in particular relates to a 2D forming tool and a forming process for a card-generating motor copper wire. Background technique [0002] Hairpin permanent magnet synchronous motors (also known as flat wire motors or hairpin motors) are gradually being widely used in the domestic drive motor market. Compared with traditional wound motors, due to the flat characteristics of Hairpin copper wires, under the same power, they can Making the motor smaller is the development direction of the next generation of new energy vehicle drive motors. It is more difficult to make the coil of the motor rotor with flat copper wire than the round copper wire coil, and the shape parameters of each layer of copper wire of the stator copper wire core of the Hairpin motor are different, especially the bending process of the flat copper wire of the large motor rotor has always been ...

AI Technical Summary

Problems solved by technology

It is more difficult to make the coil of the motor rotor with flat copper wire than the round copper wire coil, and the shape parameters of each layer of copper wire of the stator copper wire core of the Hairpin motor are different, especially the bending process of the flat copper wire of the large motor rotor has always been the motor A difficult point in the manufacture and repair of rotors, which is time-consuming and labor-intensive without special tools
