Hairpin motor copper wire 2D forming tool and process

Abstract

The invention relates to a hairpin motor copper wire 2D forming tool. The hairpin motor copper wire 2D forming tool comprises a base plate, a plurality of positioning holes formed in the base plate, angle positioning pieces arranged on the base plate through the positioning holes and adjustable in position, a middle column fixedly arranged on the base plate, a rotating disc rotatably connected to the middle column, a handle connected to the outer side face of the rotating disc, a wire groove fixedly formed in the upper portion of the base plate, an adjusting block connected to the wire groove in a sliding mode and a blocking column detachably connected to the rotating disc, the blocking column and the wire groove are arranged in the radial direction of the middle column, the outer wall of the inner end of the blocking column is close to the inner end of a channel, the top ends of the angle positioning pieces are higher than the bottom end of the handle, and the contact faces of the handle and the angle positioning pieces are inclined faces. According to the hairpin motor copper wire 2D forming tool, flexible machining of a flat copper wire can be achieved, and the machining requirement for the shape of each layer of copper wire is met; and the hairpin motor copper wire 2D forming process is flexible in setting and convenient 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 applied on a large scale in the domestic drive motor market. Compared with traditional wound motors, due to the flat characteristics of Hairpin copper wires, under the same power, 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 b...

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
